Description

TECHNICAL AREA

[0001] The present invention relates to a corrugated web beam composite structure comprising at least one corrugated web beam and at least one crossbeam arranged transversely to the longitudinal extent of the corrugated web beam, wherein the corrugated web beam has a top flange and a bottom flange and a corrugated web extending between the flanges, wherein the corrugated web beam and the crossbeam are / are connected to each other by a material bond, at least in the region of the corrugated web. Furthermore, the present invention also relates to the computer-aided implementation of a method for forming such a corrugated web beam composite structure, particularly for structural applications. Finally, the present invention also relates to a computer program product for generating a digital twin of such a corrugated web beam composite structure.The invention relates to the structural design and the use of a crossbeam or crossbeam connection or cross-strut arrangement, each for providing a connecting piece to be materially bonded to a corrugated web beam, e.g., in the form of a diagonal stiffener, for providing a crossbeam arrangement to form such a corrugated web beam material bond construction. In particular, the invention relates to a corrugated web beam material bond construction and a computer program product according to the preamble of the respective independent claim. BACKGROUND OF THE INVENTION

[0002] In structural engineering, particularly in roof construction, it is crucial for many structures to achieve high structural strength while simultaneously minimizing their own weight and material requirements, especially when large spans need to be bridged without support. For such purposes, corrugated web beams have proven to be an advantageous profile. These beams (such as I-beams) have a top and bottom chord and a profiled corrugated web running between the chords, for example, a more or less wave-like web. The corrugated web is designed to be as material-efficient as possible (thin, small material thickness) and is also curved inwards and outwards in the transverse direction (e.g., with a wave-like profile), particularly to increase strength, stiffness, load-bearing capacity, or other static or dynamic strength properties.

[0003] Corrugated web beams typically extend in more or less only one dimension, referred to here as the longitudinal direction or longitudinal extent. If multidimensional structures are to be formed using corrugated web beams, beam components oriented or arranged transversely to the corrugated web beam are typically used. These components are butt-jointed to the corrugated web beams, in particular by a material bond, usually by welding. The butt joint can be located, for example, in the area of ​​the corrugated web, and in particular exclusively there, i.e., not at the top or bottom flange. However, this presents a difficulty, especially in practical fieldwork, i.e., during construction / assembly: The laterally bulging, corrugated (e.g.,The corrugated cross-sectional profile of the corrugated web results in a transverse offset of the butt surface intended for connection, which depends on the longitudinal position and can vary by several millimeters or even centimeters (depending on the wave height / depth of the profile, e.g., between 0 mm and 15 mm, or even over 20 mm). Therefore, it is not always possible to predict exactly the relative position of the corresponding transversely arranged support component when it meets the corrugated web. The associated or necessary fine-tuning is comparatively complex and may, for example, require subsequently cutting the respective transversely arranged support component to the exact length required for a butt joint.

[0004] The corrugated web girders considered here can have comparatively large dimensions, e.g., heights exceeding one meter (e.g., 1.5 m), and be designed for spans exceeding 35 m. Particularly in such large-scale applications, it can be crucial to further improve the corrugated web girder's load-bearing capacity and / or transverse connection, for example, by adding transverse stiffeners. Profiled I-beams with wave-like, especially sinusoidal, webs (so-called SIN profiles or SIN girders) are used in steel construction, for instance, to bridge medium to large spans in the most cost-effective and economical way possible, thanks in particular to their advantageous compromise between load-bearing capacity, self-weight, and material usage.Transverse stiffeners, i.e., structural load-bearing components (stiffening components) attached or integrated transversely to the longitudinal extent of the corresponding corrugated web beam, serve both to ensure the safe transfer of loads and to increase the local and overall stability of the beam. Transverse stiffeners are typically bonded to the corrugated web beam. The specific geometry of the wave-like (profiled), especially sinusoidal, web, as well as the not clearly defined location of the apex, trough, and inflection points in the geometric, especially wave-like, course of the web profile—a consequence of roll forming processes for such I-beams—make the precise geometric arrangement of such transverse stiffeners relative to the corrugated web beam particularly difficult.In some applications, the transverse stiffeners should, particularly at certain relative longitudinal positions, not only terminate at the web but also, ideally, flush with the outer edge of the flange. However, since the distance between the corrugated web and the outer edge of the flange varies along the wavelength and depending on the longitudinal position (and is not always exactly constant), achieving consistently flush alignment of the transverse stiffeners is either impossible, only possible with insufficient precision, or only achievable with increased effort and correspondingly higher costs.

[0005] Three main solutions are known from the current state of the art: The transverse stiffeners can be measured manually, meaning they can be individually cut to width for each installation position. Alternatively, continuous stiffeners can be routed from one outer flange edge to the other through web penetrations. Or, short stiffeners with a narrow width can be provided by connecting them either to the web or to the outer flange edge. While these solutions are largely easy to implement from a design perspective, they either result in high manufacturing costs (especially for web cutouts or penetrations and the associated additional corrosion protection required in the penetration / cutout areas) or in limited load-bearing capacity (with structural disadvantages) and restricted standardization. This significantly hinders largely automated, series production.There is therefore interest in an improved design of such corrugated web girder constructions, on the one hand with regard to the broadest possible range of applicability, and on the other hand also with regard to improved conditions concerning design, stiffness and similar boundary conditions in the planning, construction and realization of structures, e.g. for roofs.

[0006] An example is publication DE 10 2017 114 558 A1, which describes a method for manufacturing a corrugated web beam profile of the type.

[0007] Based on the current state of the art, there is a need for measures to optimize the use of corrugated web beams in combination with crossbeam components, particularly with regard to the practical implementation of construction / assembly work to form the structure from corrugated web beams that are bonded together in the area of ​​the web, especially welded together, and beam components that are typically oriented or arranged transversely to the corrugated web beam. Last but not least, there is also interest, particularly with regard to practicality and feasibility, in the simplest possible implementation with reduced complexity, low material requirements, and minimal effort with respect to the bonded connections to be created. SUMMARY OF THE INVENTION

[0008] The objective is to provide measures for the simplified use of corrugated web beams, particularly in structural applications, thereby facilitating the implementation of material-bonded connections between a corrugated web of the beam and other beams or beam components, whether for the execution of the structure itself or for its computer-aided planning and design, e.g., using a digital twin. It is also a task to design a structure based on one or more material-bonded connections, consisting of corrugated web beam(s) and at least one other beam or beam component positioned transversely to it, in such a way that the material-bonded connection to the corrugated web can be realized in a particularly elegant and flexible manner with a minimized number of standardized / standardizable components or beam components as connection partners.The invention is based in particular on the objective of providing constructive and manufacturing improvements for corrugated web beam constructions equipped with transverse stiffeners or the like oriented transversely to the corrugated web beam, by means of which a corrugated web beam construction can be realized that overcomes the disadvantages described above, in particular a corrugated web beam construction in which the transverse stiffeners can be guided flush with the outer edge of the flange and the web, and which does not require penetration of the web or web cutouts, and which ensures good welding accessibility for as many essential connections as possible, while at the same time supporting the feasibility of series production suitable for automation.In this context, it is particularly important with regard to standardizability to design the corrugated web beam construction in such a way that a standard-compliant surface treatment (e.g. hot-dip galvanizing or coating) can be easily enabled, and that the corrugated web beam construction can be realized with standardizable dimensions of the stiffening components and that a load-bearing capacity at least at the level of conventional stiffener designs can be achieved or even exceeded without difficulty.

[0009] This problem is solved by a corrugated web carrier material connection construction according to claim 1, by a computer-aided implementation according to a computer program product according to the corresponding dependent claim, and by uses according to the dependent use claim. Advantageous embodiments of the invention are explained in the respective dependent claims. The features of the exemplary embodiments described below can be combined with one another unless explicitly stated otherwise.

[0010] A corrugated web beam material connection structure is provided, comprising at least one corrugated web beam or its digital twin and at least one crossbeam or its digital twin, which is arranged transversely, in particular orthogonally, to the longitudinal extent of the corrugated web beam, wherein the corrugated web beam has a top chord and a bottom chord and a corrugated web extending between the chords, e.g., corrugated or trapezoidal, wherein the corrugated web beam is brought / is ...A cross-stiffening arrangement is connected to a connecting piece that projects obliquely from the crossbeam at a predefined angle of angle other than 0° and 90°, and extends beyond the end of the crossbeam towards the corrugated web beam. This connecting piece provides a material-fit connection to the corrugated web, particularly by including two unequal angles relative to the longitudinal extent of the corrugated web beam. This offers, on the one hand, an advantageously variable yet structurally uniform stiffening concept, and on the other hand, allows for a particularly elegant and load-bearing-adjustable transverse connection to the corrugated web beam.

[0011] The connecting piece can be aligned relative to the corrugated web by means of a predefined offset angle, provided the crossbeam is properly arranged / oriented, such that the crossbeam can be bonded to the corrugated web at a variable longitudinal position along the web using the connecting piece. This is particularly relevant when the relative transverse position of the crossbeam is predefined relative to the corrugated web (e.g., with a structurally or design-predefined transverse distance), for example, with regard to a flush finish at the outer edge of the flange. The offset angle can correspond to the weld angle between the end face of the crossbeam and the connecting piece.

[0012] The invention is therefore also based on the concept of proposing an optimized design method or approach for optimizing the design of stiffened corrugated web beams, particularly with regard to a particularly advantageous embodiment of stiffening elements acting directly on the corrugated web, here generally referred to as crossbeams (arrangement), in particular comprising stiffeners, transverse stiffeners, lateral stiffeners, stiffening elements, in particular multi-leg stiffeners, transverse connections, load introduction stiffeners, and transverse introduction stiffeners. The invention provides for at least one additional stiffening element in an oblique arrangement, which is also described here as a connecting piece. The embodiments described here can be advantageously implemented generally for corrugated web beams, profiled webs, welded I-beams with a sinusoidally profiled web or sinusoidal cross-sectional geometry of the web, in particular for SIN beams.Furthermore, the invention also relates to measures for optimizing the material connections advantageously associated with the proposed construction, in particular the arrangement and design of welds on the connection / joining partners of the involved crossbeam connections or stiffeners described herein, i.e., firstly, a transverse connection in the transverse direction at the joining partners crossbeam / transverse stiffener and connecting piece / diagonal stiffener on the one hand, and connecting piece / diagonal stiffener and corrugated web on the other hand, and secondly, optionally also a material-bonded connection in the vertical direction downwards and / or upwards, particularly within the corrugated web beam flange, i.e., to the bottom and / or top flange. Moreover, requirements regarding corrosion protection are also taken into account within the scope of the present invention, in particular to ensure a design of the corrugated web beam construction such that certain coating systems (e.g.,The requirements associated with hot-dip galvanizing, iron-zinc alloy formation, and liquid coatings can be met without any problems.

[0013] Insofar as the present disclosure refers to a corrugated web beam material connection construction, this means, on the one hand, an assembly comprising at least one corrugated web beam and at least one correspondingly designed crossbeam according to the present disclosure, and on the other hand, synonymously, a correspondingly materially connected construction, whether it is pre-assembled or already fully installed in the field, and synonymously also the construction as such, in particular in the form of construction plans, data, digital twins or the like.

[0014] Insofar as the present disclosure refers to "formation" or a method for forming, this includes, on the one hand, a manufacturing process as such with regard to the device-related design, and on the other hand, a purely data-driven or computer-aided creation of the construction(s) described here in virtual space, in the form of construction drawings, and / or within the framework of modeling or simulation.

[0015] Where the present disclosure refers to a corrugated web (beam), this term is synonymous with a corrugated web (beam) with a repeating geometry that may not be shaped like a more or less sinusoidal wave, i.e., it does not necessarily have to be corrugated; for example, it may also have a more angular, e.g., trapezoidal, cross-section. Furthermore, the corresponding corrugated web beam is not limited to only one type of cross-sectional profile, but may also have different profile sections along its longitudinal extent.

[0016] Where the term "bridge" is generally used in the present disclosure, it is to be understood synonymously as referring to the corrugated web of the corrugated web support.

[0017] Where the present disclosure refers generally to a wave or to terms introduced by "wave..." or "well...", this is to be understood synonymously as a reference to a profile of the web that is not necessarily wavy or sinusoidal, but also, for example, to a trapezoidal profile, which may likewise have a certain height (peak-valley value, wave height) or amplitude and period or wavelength. The wavelength of typical web beams is, for example, 155 mm.

[0018] Insofar as the present disclosure refers to "wave-like", this is to be understood synonymously as a general reference to a profiled geometry, here, with reference to the web of the corrugated web beam, thus a reference to a web with, for example, a wave-like profile. In this respect, the term "wave-like" or "profiled" can also refer, for example, to the web of a trapezoidal sheet metal beam.

[0019] Where the present disclosure refers to a connecting piece, this term is synonymous with a section of the crossbeam projecting from the crossbeam, regardless of how this section or connecting piece is provided or designed on the crossbeam (e.g., integrally, or connected to a main member of the crossbeam). Therefore, the crossbeam with connecting piece can optionally be provided as an integral, one-piece crossbeam, or alternatively as a multi-part assembled or materially bonded component or assembly. The materially bonded connecting piece is, by design, oriented at an oblique angle relative to the longitudinal extent of the corrugated web beam.

[0020] Where the present disclosure refers to crossbeams, this is to be understood synonymously as a general reference to a stiffening element (beam component) such as a transverse stiffener or a crossbeam connection (structural component for connecting a crossbeam component or similar transversely arranged beam component). A general reference to crossbeams, therefore, according to the present disclosure, is also to be understood as a reference to a crossbeam connection or transverse stiffener arrangement acting in the same way, i.e., generally as a reference to a transversely extending stiffener and optionally also to the connection of further crossbeam components, each of which is designed such that a material-bonded connection to the corrugated web can be realized directly or indirectly in the manner described herein.In other words, the so-called crossbeam does not necessarily have to project laterally beyond the corrugated web beam in the transverse direction; however, the crossbeam can, for example, also be part of a more extensive crossbeam connection or crossbeam arrangement in which further structural load-bearing components are also provided that extend significantly laterally beyond the corrugated web beam flange, for example, in comparatively large-dimensioned, self-supporting, bridging roof structures. The crossbeam is advantageously also connected to the upper and lower chords of the corrugated web beam by means of a material bond. The connecting piece that interacts with the corresponding crossbeam component or transverse stiffener according to the invention can also be referred to as a diagonal stiffener in this context (especially since it is not intended to be orthogonal).(not perpendicular to the longitudinal extent of the corrugated web beam, but oriented obliquely to it). The crossbeam or cross stiffener can extend laterally / transversely beyond the flange sides of the corrugated web beam, for example, in a structurally load-bearing manner with other components from the following group: another corrugated web beam, rolled section beam, trapezoidal sheet metal beam, truss beam, Vierendeel beam, another preferably standardized profile beam, e.g., I-beam or the like.

[0021] It should be understood that the approach described here for designing stiffening and transverse connections, particularly using the components described here, can be combined with various other beam types besides the corrugated web beams described here, especially rolled section beams (e.g., with IPE, HEA, HEB profiles), trapezoidal sheet metal beams, truss beams, and Vierendeel trusses. The implementation of the design described here is particularly recommended in areas with high bending moment loads, for example, in the intermediate support area.

[0022] When the present disclosure refers to a material bond, this primarily means a welded joint, but synonymously also, for example, another material bond such as an adhesive bond or any other adhesive connection that can ensure a material bond between the joining partners. When the present invention generally refers to a welded joint, this can be understood to include, in particular, the following types of welded joints: manual arc welding and gas metal arc welding, especially metal active gas welding, as well as the types of welds produced by these processes, e.g., fillet welds, butt welds, butt welds with a so-called HV joint.

[0023] Where the term "flange" is used in this disclosure, it is to be understood synonymously as the cross-sectional profile of the corrugated web beam, including the top and bottom flanges. The outer edges of the flange therefore correspond to the longitudinal edges along the corrugated web beam (corresponding to the outer edges of the top flange / top flange and the bottom flange / bottom flange), with the top and bottom flanges typically having the same width / thickness. The flange width is therefore to be understood as the standard width of the corrugated web beam.

[0024] The present invention also takes into account, in particular, a design concept in which a respective corrugated web beam is interpreted or designed, especially from a static-mechanical perspective, at least essentially as a truss beam, in which bending moments and axial forces are absorbed at least predominantly via the chords (top and bottom chords, or top and bottom flanges), while the shear forces are transmitted at least substantially, preferably exclusively, by the profiled web. This approach can be applied to various, in principle all possible, profiled beam types, including those with top and bottom chords of different thicknesses. In this way, the present invention can also provide a generally understandable concept for those skilled in the art and adaptable to different beam components.provide a viable approach to optimizing the design of structural designs using corrugated web beams.

[0025] Where the present disclosure refers to an oblique angle or oblique orientation of the connecting piece, this designation is also figuratively described in exemplary embodiments as "diagonal" or diagonal orientation, e.g. in the context of the diagonal stiffener explained here by way of example; these terms are to be understood synonymously here, and the term "diagonal" is not to be understood in a strictly geometric sense as a diagonal between two geometrically precisely predefined points, but rather in the sense of a connecting stiffening stiffener arranged obliquely to the longitudinal extent of the corrugated web beam and obliquely to the transverse direction and materially bonded between the transverse beam component and the corrugated web or corrugated web beam.

[0026] Personalized terms, unless explicitly formulated in the neuter gender, may refer to all genders within the context of this disclosure. Any foreign-language expressions or abbreviations used here are standard industry terms and are familiar to those skilled in the art. Any synonymous German terms used / available may be indicated here in parentheses for the sake of completeness, or vice versa.

[0027] It is understood that the implementation of AI models within the scope of the present invention, e.g., also insofar as a computer-aided determination of at least one particularly preferred angle is concerned (e.g., angle of deflection or relative angle at the web web or relative to the longitudinal extent of the web web support), may include a computer infrastructure or data processing architecture, in particular also in the core of at least one computing unit, which facilitates and / or makes more powerful or faster (up to real-time processing) and / or makes more energy-efficient or at least partially makes it possible in the first place.In particular, decision-making processes of neural AI networks can be implemented relatively quickly and (energy) efficiently, especially in end devices (edge), for example also in the context of data processing and data storage, for example for energy-optimized data storage, and / or in connection with the use of spin losses or in combination with so-called spintronic measures, especially also in the case of particularly small and energy-saving semiconductor components.For example, the computer-based and chip-based tools described here include at least one of the following components: photonic AI chips, especially those with silicon photonic structures (a combination of electronic and optical data processing), spintronic semiconductor devices, optical waveguides at least partially replacing or supplementing electronic semiconductors, as well as multiplexing components, photon modulators, photodetectors, ring resonators, at least one dense wavelength division multiplexing (DWDM) component for the simultaneous processing of multiple data channels, at least one optical circuit integrated into at least one neural network (NN) or deep neural network (DNN), and at least one photonic processor. For example, at least one NN and / or DNN is executed directly at the hardware level. As a result, particularly large datasets can be analyzed very quickly.For example, at least one photonic component is present in form printed directly onto a wafer, in particular at least one of the following photonic components: optical amplifiers, photonic integrated circuits (PICs), polarization converters, splitters, optical waveguides, phase modulators. It should be understood that, in addition to such infrastructure specialized for AI applications, an implementation of so-called Neural Architecture Prediction (NAP) methods can also be used alternatively or additionally; AI models based on these can, for example, also be combined with AI architectures such as transformers, LSTM (Long Short-Term Memory), GNN (Graph Neural Network), etc.neural networks (specialized for processing information based on graphics and charts) and / or RNNs (Recurrent Neural Networks) can be combined, especially for the purpose of implementing AI measures even on at least partially comparatively old hardware, which is (still) not necessarily designed at the hardware level for an optimized application of AI measures.

[0028] According to one embodiment, the corrugated web beam construction has at least two crossbeams and at least one connecting piece, wherein a first crossbeam is provided on a first lateral side of the corrugated web and a second crossbeam is provided on one / the opposite second lateral side of the corrugated web, in particular in the same longitudinal position, wherein optionally only one of the crossbeams interacts with a / the connecting piece or both crossbeams each interact with a connecting piece, wherein the corresponding arrangement is preferably repeated at at least one further longitudinal position of the corrugated web beam, in particular in the same relative longitudinal position relative to the phase of the (wave) progression of the profiling of the corrugated web.This also promotes a systematic stiffening of the structure along comparatively large lengths, whereby the respective longitudinal position for the corresponding transverse stiffening and / or transverse connection can be defined in a comparatively flexible or variable way.

[0029] According to one embodiment, crossbeams act laterally on both sides at the same longitudinal position in pairs with the corrugated web, either without an interposed connecting piece or in combination with the corresponding connecting piece. In other words, the crossbeam (or transverse stiffener) and the connecting piece (or diagonal stiffener) are preferably dimensioned and structurally coordinated in such a way that their use can be realized in the most flexible / variable way possible, individually or in combination with each other, for a material connection in conjunction with the corrugated web. This also allows for a further reduction in the components required for the realization of the construction described here, e.g., a reduction to only two or three standard components.

[0030] It is important to understand that the three different types of beam components (two types of crossbeams, one type of connector) and three different stiffener types (transverse stiffeners S1, S2, and diagonal stiffener S3) described here in detail as examples are advantageously designed to enable a straightforward, precise, and reproducible arrangement and connection of the beam components or stiffener elements, even under challenging structural conditions and positional relationships. Inflection points, invert points, and vertices serve as geometric reference points, facilitating positioning and welding. In principle, however, the beam components or stiffener elements can be arranged along any longitudinal position of the corrugated web.The modular design of the corrugated web beam construction described here allows for flexible adjustment of the positions within the wavelength, provided the basic geometric specifications and connection conditions are met.

[0031] According to one embodiment, the corrugated web and the connecting piece, in their intended, materially bonded arrangement, enclose a first and a second angle at the corrugated web in the intended connection area, with the first and second angles being of different magnitudes. This can, on the one hand, improve welding accessibility from the outside laterally, and on the other hand, it allows for a relatively angular arrangement that makes it possible to ensure the materially bonded connection to the corrugated web largely independent of the relative longitudinal position of the transverse connection relative to the profiling (or relative to the phase of the corrugation) in a uniform or predefinable manner, and in particular to predefine the design of the respective weld seam.

[0032] According to one embodiment, the corrugated web and the connecting piece, in their intended, materially bonded arrangement, together form a first enclosed angle (particularly pointing laterally inwards at the corrugated web support flange), which is acute, particularly of a maximum of 70°, and especially in the range of 50 to 60°. This also facilitates high variability with regard to relative positioning and good accessibility. The acute angle is preferably an internal angle pointing towards the central longitudinal axis of the corrugated web support.

[0033] According to one embodiment, the corrugated web and the connecting piece, in their intended, materially bonded arrangement, together form a second enclosed angle (particularly external, pointing laterally outwards at the corrugated web support flange), which is obtuse, in particular at least 110°, and especially in the range of 120° to 130°. This also facilitates high variability with regard to relative positioning and good accessibility. The obtuse angle is preferably an external angle pointing away from the corrugated web.

[0034] According to one embodiment, the offset angle is in the range of 10 to 35°, preferably in the range of 15 to 30°. For example, the offset angle is 20° or 25°. This also allows for high variability with regard to relative positioning and good accessibility. For example, the (inner) weld angle between the end face of the cross member and the connecting piece is then 20°, or the outer weld angle is then, for example, 70°.

[0035] According to one embodiment, at least one first material connection, in particular a butt weld, is provided in the intended connection area between the connector and the corrugated web, and / or at least one second material connection, in particular a fillet weld, is provided in the intended connection area between the crossbeam and the connector. This also provides an advantageous compromise between accessibility and weldability, optimization of the corresponding material connection, particularly with regard to load conditions in the relevant relative position, and integration of the crossbeam arrangement into the corrugated web beam flange, optionally also in combination with further material connections on the top and / or bottom flange. The butt weld can advantageously be designed as a T-joint with a high-strength joint. The fillet weld can advantageously be designed as a T-joint with an end-face joint.The crossbeam arrangement is designed for corrugated web material joining, i.e., for material joining with the corrugated web as an additional joining partner, whereby, on the part of the crossbeam arrangement, either one or the crossbeam can be directly or the connecting piece can be indirectly provided for material joining with the corrugated web as an additional joining partner.

[0036] It has been shown that the welded joints between the diagonal stiffener or the connecting piece and the web are advantageously executed as butt welds (welds executed on the end face) in a T-joint configuration, particularly with a high-strength joint. The construction described here is therefore dimensioned such that the end face of the diagonal stiffener abuts laterally against the web (possibly maintaining a gap), so that these two components can form a kind of T-shaped joint configuration. The end face of the diagonal stiffener can be formed with flanks on one or both sides, depending particularly on the material thickness of the diagonal stiffener. For stiffener thicknesses (d s3 For a thickness of 3 mm to 10 mm, a single-sided flank is preferred, especially for a high-strength joint. From a stiffener thickness (d) s3For cross-sections ≥ 11 mm, a high-strength weld (HV) joint can advantageously be applied to both sides of the end face of the diagonal stiffener, while fillet welds run laterally along the abutting component edges. In this case, flank angles of the HV joint in the range of 35° in combination with a camber of 1 mm to 2 mm have proven particularly advantageous. This design increases the effective contact length of the weld joint at the end face of the diagonal stiffener (S3), while simultaneously minimizing the lateral extent of the flank along the diagonal stiffener. This configuration has proven particularly advantageous in areas near wave crests or troughs, especially with regard to sufficient installation space / access for lateral welding (fillet welds) between the transverse stiffener and the diagonal stiffener. Excessively acute flank angles, especially of the HV joint, would reduce the usable orHowever, this could adversely restrict the available welding space, especially in this area.

[0037] According to one embodiment, the intended connection area for the connector on the side of the corrugated web is defined by an obliquely angled section of the web's abutment surface. In other words, in combination with the connector, the respective beam can be connected to the corrugated web in relative longitudinal positions where a direct, material-bonded connection between the crossbeam and the corrugated web would otherwise not be readily possible. Additionally, a direct connection between the crossbeam and the corrugated web can also be achieved in relative longitudinal positions where the corrugated profile passes through the respective apex or sill point, thus providing at least an approximately orthogonal abutment surface for the crossbeam. With the proposed reduction in the number of standard components, the crossbeam is advantageously connected to the corrugated web at the surface sections at the respective apex.

[0038] According to one embodiment, the intended connection area on the side of the connector is defined by the free end of the connector, in particular by an end face with first and second end faces in specific angular orientations. This also facilitates the type of material-bonded connection between the connector and the corrugated web, especially with regard to standardizability, which is largely independent of the relative longitudinal position on the corrugated web, and also with regard to accessibility.

[0039] According to one embodiment, the end face of the crossbeam, which is intended to face the corrugated web, is oriented at an oblique angle, preferably at a seam angle of 20°, and in particular with the seam angle corresponding to the offset angle. This also promotes good stiffness and high load-bearing capacity, especially since the connecting piece can be brought into the intended relative oblique orientation by contacting the end face of the crossbeam over a flat surface and can advantageously be connected to the crossbeam at several material-bonded connection points (points or lines), particularly with regard to maximizing the structural load-bearing advantages achievable by means of the arrangement described here.

[0040] According to one embodiment, an end face of the connector, which is intended to point towards the corrugated web, has at least one obliquely angled end face, preferably two obliquely angled end faces or one obliquely angled end face and a raised section, more preferably an obliquely angled end face at a seam angle in the range of 30 to 40°, in particular 35°, in combination with a raised section, preferably with a width in the range of 2 mm. This facilitates both the material-bonded connection itself and its creation.

[0041] Especially with a butt weld in a T-joint configuration with a high-strength joint, it has proven advantageous to provide a side flank with a weld angle δ = 35° in combination with a camber c of approximately 2 mm. This also allows for a large contact length of the weld joint between the connector and the web without adversely affecting the weld joint between the connector and the corresponding crossbeams / stiffeners (S1, S2). At the same time, good accessibility for welding equipment can be ensured. When preparing the weld as a butt weld, the welding can preferably be carried out along the entire end face of the diagonal stiffener; an additional weld on the inner side between the diagonal stiffener and the corrugated web can be omitted.

[0042] For example, the corrugated web has, at least in sections, a corrugated profile, particularly a sinusoidal profile, with a web angle in the range of 40°, where the offset angle is in the range of 15° to 25°, e.g., 20°. Alternatively, the corrugated web has, at least in sections, a trapezoidal profile with a web angle in the range of 40°, where the offset angle is in the range of 15° to 25°, e.g., 20°. The offset angle or seam angle described here can remain at least approximately the same at the end face of the crossbeams or cross stiffeners; that is, the design concept described here is transferable to different corrugated web configurations. It has even been shown that an offset angle preferred for a corrugated web can also be considered preferred for a trapezoidal corrugated web.

[0043] It is important to understand that, from a structural and static perspective, corrugated and trapezoidal web profiles behave very similarly, so that there is hardly any need to differentiate between the two in terms of their design. For trapezoidal sheet metal beams, the typical web angle is approximately 40°. For sinusoidal webs, the same angle of approximately 40° is generally assumed from a static point of view (the continuous wave pattern of the SIN profile allows for an effective mean web angle of, for example, just under 40°). The widths in the area of ​​the troughs and apex are also comparable for both profile shapes. However, a structural difference must be mentioned in the way the webs behave under load: trapezoidal webs behave like plates under load, while sinusoidal webs (SIN webs) act more like shells.The present invention takes this into account in that the mechanical advantage with regard to load-bearing capacity and stability of the SIN beams is not additionally taken into account, but rather a dimensioning and design specification for the corrugated web beams is based on the capabilities of trapezoidal sheet metal beams, which leads to the conclusions made here regarding load-bearing capacity being very conservative and already including a good safety factor, at least in the case of corrugated web profiles, meaning that the actual load-bearing capacity is deliberately and systematically underestimated here, at least in the dimensioning process for corrugated web profiles.

[0044] The aforementioned problem is also solved by a structural design with at least one corrugated web beam material connection design according to the present disclosure.

[0045] The aforementioned problem is also solved by a computer-aided implementation or by a computer program product comprising instructions which, when the computer program product is executed on a computer, cause the computer to form a corrugated web beam material connection structure according to the present disclosure or its digital twin, or to execute steps for forming a digital twin of a corrugated web beam material connection structure according to the present disclosure based on a method implemented as a digital twin according to the present disclosure on the computer, namely based on a method for forming a corrugated web beam material connection structure, in particular for structural constructions, from at least one corrugated web beam and at least one crossbeam arranged transversely, in particular orthogonally, to the longitudinal extent of the corrugated web beam.wherein the corrugated web beam is, as intended, brought into material contact with the at least one crossbeam at least in the area of ​​the corrugated web of the corrugated web beam, in particular by a welded connection; wherein the at least one crossbeam is / is connected to a connecting piece projecting obliquely from the crossbeam at a predefined angle of projection other than 0° and other than 90° and extending beyond the end of the crossbeam in the direction of the corrugated web beam, wherein the corrugated web beam material connection is formed by bringing the corrugated web beam into contact with the crossbeam in at least one longitudinal position of the corrugated web beam by indirectly connecting the crossbeam and the corrugated web beam by materially connecting the connecting piece and the corrugated web beam (by at least one materially connected connection) in the area of ​​the corrugated web.This is particularly true when using a corrugated web carrier material connection construction according to the present disclosure. This results in the aforementioned advantages, especially with regard to the most efficient and standardized implementation possible on-site in the field at the respective installation location of a building structure.

[0046] Such a computer-aided implementation can also refer to a design procedure for the design of the structural load-bearing components of the corrugated web girder construction, i.e., to an implementation for a computer-aided design and planning method.

[0047] It is also understandable that the design and manufacturing approaches according to the invention enable a modular and repeatable structure: A systematic repetition of the arrangement (relative positions) of crossbeams and connecting pieces (transverse / stiffening elements) at defined longitudinal positions also promotes a standardized, scalable assembly process with minimal need for individual adjustments. This is accompanied by an advantageous reduction in the variety of component variants: The procedural application of such a modular concept also allows for a limitation of the number of different component types. This ultimately simplifies logistics, quality control, and warehousing.Furthermore, automation compatibility can be ensured in an optimized manner: Standardizing the (relative) position and installation sequence of the involved transverse / stiffening elements facilitates integration into automated systems for welding, positioning, or inspection, thereby increasing the productivity and efficiency of industrial manufacturing and assembly processes. This can be particularly advantageous for hard-to-reach structural elements in the roof area, such as those found in large industrial buildings. Finally, a comparatively high degree of flexibility regarding system expansion, retrofitting, and maintenance can be guaranteed: The concept described here also offers advantages for future expansions, the replication of existing structures, and maintenance and repair measures.

[0048] According to one embodiment, the connecting piece is aligned at a predefined angle relative to the surface of the corrugated web, with the intended oblique orientation relative to its longitudinal extent, such that the crossbeam can be indirectly connected to the corrugated web via the connecting piece in a variable longitudinal position along the corrugated web, particularly in a section of the corrugated web running obliquely to the end of the crossbeam or its end face, and especially with a predefined relative transverse position of the crossbeam relative to the corrugated web. This also facilitates trouble-free manufacturing and assembly, particularly due to good accessibility.

[0049] According to one embodiment, the corrugated web and the connecting piece, in an arrangement intended to be materially bonded to one another, enclose a first and a second angle in the intended connection area on the corrugated web, wherein the first and second angles are of different magnitudes.

[0050] According to one embodiment, the corrugated web and the connecting piece, in their intended relative arrangement to each other, form a first enclosed angle which is acute, in particular a maximum of 70°, and in particular lies in the range of 50 to 60°.

[0051] According to one embodiment, the corrugated web and the connecting piece, in their intended relative arrangement to each other, form a second enclosed angle which is obtuse, in particular at least 110°, and in particular in the range of 120 to 130°.

[0052] According to one embodiment, the computer-aided implementation for at least one longitudinal position and / or for a further longitudinal position along the corrugated web support further comprises: immediate, direct, material-bonded connection of the corrugated web and crossbeam, in particular crossbeam of a / the first type. This can also ensure a comparatively simple design, with a comparatively small number of material-bonded connections and a minimized number of components.

[0053] According to one embodiment, the computer-aided implementation for the at least one longitudinal position and / or for a further longitudinal position along the corrugated web beam comprises: indirect connection of the corrugated web and crossbeam, in particular crossbeam of a first type, by means of the connecting piece by material-bonding connection of the corrugated web and connecting piece on a first lateral side of the corrugated web beam, and indirect connection of the corrugated web and crossbeam, in particular crossbeam of a second type, by means of the connecting piece by material-bonding connection of the corrugated web and connecting piece on one / the second opposite lateral side of the corrugated web beam.

[0054] According to one embodiment, the computer-aided implementation for the at least one longitudinal position and / or for a further longitudinal position along the corrugated web beam comprises: indirect connection of the corrugated web and crossbeam, in particular crossbeam of a first or second type, by means of the connecting piece by material-bonding connection of the corrugated web and connecting piece on a first lateral side of the corrugated web beam, and immediate, direct material-bonding connection of the corrugated web and crossbeam, in particular crossbeam of a / the first type.

[0055] The aforementioned problem is also solved by a computer program product comprising commands which, when the computer program product is executed on a computer (or analogously on a computing unit of a welding robot or similar manufacturing / assembly aid), cause it to form a corrugated web beam material connection structure according to the present disclosure or its digital twin, or to execute steps for forming a digital twin of a corrugated web beam material connection structure according to the present disclosure based on a method implemented as a digital twin according to the present disclosure on the computer, in particular a computer program product configured to execute an algorithm on the computer depending on the geometric course of a corrugated web of a corrugated web beam, in particular depending on geometric data relating to its cross-sectional profile, for defining at least one value,Parameter or amount from the following group for forming / creating a corrugated web support material connection structure or a structural construction, each according to the present disclosure: Amount of a connecting piece's offset angle relative to a crossbeam, and / or Amount for the width of at least one type of crossbeam (or cross stiffener) and / or for the width of the connecting piece, and / or Value, in particular limit value for the (sheet) thickness of at least one type of crossbeam (or cross stiffener) and / or for the (sheet) thickness of the connecting piece, and / or value, in particular limit value for at least one weld length and / or at least one weld angle of at least one weld joint between corrugated web and crossbeam and / or between corrugated web and connecting piece and / or between connecting piece and crossbeam, and / or Parameters, in particular welding parameters, for creating at least one metallurgical bond between at least two of the joining / joining partners (corrugated web, connecting piece, crossbeam), especially welding parameters of a MAG or manual arc welding process. Based on the aforementioned advantages, this also enables a particularly easy and application-specific adaptable method of implementation.

[0056] Advantageously, boundary conditions or requirements related to suitable welds (butt or fillet welds), joint types (butt, T, or corner joints), joint shapes (e.g., V, X, or K joints), required weld angles, as well as width, height, and tolerance dimensions of the weld preparation can be taken into account. In principle, standard types of weld preparation are feasible in the design approach described here and can therefore also be implemented in a computer-aided method for dimensioning the individual beam components, especially cross-strut widths, particularly to achieve the most cost-effective stiffener design possible.

[0057] The aforementioned problem is also solved by a computer program product comprising commands which, when executed on a computer, cause the computer to execute, depending on the geometric shape of a corrugated web of a corrugated web beam, in particular depending on geometric data relating to its cross-sectional profile, an algorithm for defining at least the magnitude of a deflection angle of a connecting piece for intended interaction with a crossbeam, designed to form / create a corrugated web beam material connection structure or a structural construction, in each case according to the present disclosure, on the computer, in particular the computer program product furthermore designed to define at least one of the following values ​​or magnitudes: magnitude for the width of crossbeam and / or connecting piece, lower or upper limit for the (sheet) thickness of crossbeam and / or connecting piece.Lower or upper limit for at least one weld length and / or at least one weld angle, respectively, between the corrugated web and cross member, between the corrugated web and connecting piece, and / or between the connecting piece and cross member. This allows the aforementioned advantages to be realized.

[0058] It is understood that the constructive approach described here, particularly when considering the mathematical relationships explained, allows all or at least most of the possible weld preparation methods to be applied in combination with different welding parameters to determine the achievable lengths of the stiffening elements involved. It is worth noting that, in the combinations of support components and relative positions described in detail here, only the weld configurations with HU and DHU joints are considered less optimal. However, this does not mean that these weld configurations could not be considered per se, for example, at other relative positions and / or additional welding points of the corrugated web beam construction.

[0059] It is also understood that the present disclosure enables a standardization or a degree of standardization which, particularly in geometric and / or mathematical terms, permits implementation such that the steps described here for creating the respective material bonds can be carried out at least partially automatically by robots or machines, e.g., for subsequent welding of the support components, especially stiffeners, to the corrugated web support, whether as part of preparatory measures or as part of final assembly. Depending on the available assembly aids, the invention also makes it possible to implement steps for aligning and positioning the individual support components, especially stiffener elements, in an at least partially automated manner.

[0060] The aforementioned task is also accomplished by a computer-readable storage medium on which a computer program according to the present disclosure and / or data of a digital twin of a corrugated web beam material connection structure according to the present disclosure is / are stored. For example, the computer-readable storage medium is provided in a welding robot or similar manufacturing / assembly aid for at least partial automation of the creation of the structure described herein.

[0061] The aforementioned problem is also solved by a crossbeam for a corrugated web beam fabric connection construction according to the present disclosure, having an end face intended for fabric connection with a connector, in particular with a predefined oblique seam angle, wherein the crossbeam is configured so that the connector projects obliquely from the crossbeam at a predefined / predefinable angle and allows one end of the crossbeam to project towards the corrugated web beam, such that the end of the crossbeam oriented towards the corrugated web beam remains without contact with the corrugated web, in particular does not overlap the corrugated web in the transverse direction. This allows the aforementioned advantages to be realized, in particular with regard to a small number of components, high variability, good scalability, and a comparatively simple design.

[0062] The aforementioned problem is also solved by a crossbeam arrangement for a corrugated web beam material-joint construction according to the present disclosure, created (computer-implemented) or manufactured by shaping (e.g., by material-joining, molding, additive manufacturing, casting / primary forming) a connecting piece on a crossbeam, designed to create a material-jointed connection with the corrugated web beam, including two unequal angles relative to the longitudinal extent of the corrugated web beam, such that the connecting piece structurally supports the load and projects obliquely from the crossbeam at a predefined angle, extending beyond the end of the crossbeam in the direction of the corrugated web beam. This allows the aforementioned advantages to be realized, particularly with regard to a crossbeam arrangement that is advantageously usable in various relative longitudinal positions.The design can define, in particular, the relative position and orientation of the connector and crossbeam. The crossbeam arrangement is configured for a corrugated web connection, i.e., a material connection with the corrugated web as an additional joining partner. The crossbeam arrangement can optionally provide either one of the crossbeams (transverse stiffener) directly or the connector (diagonal stiffener) indirectly for this material connection with the corrugated web as an additional joining partner. In other words, the crossbeam arrangement can be used either for a direct or an indirect material connection with the corrugated web as an additional joining partner.

[0063] The aforementioned problem is also solved by a corrugated web beam material connection structure according to the present disclosure, formed by generating a digital twin of a corrugated web beam and a crossbeam to be materially connected to it by means of an obliquely projecting connecting piece, wherein the corrugated web beam material connection structure further comprises the digital twin of at least one material connection, in particular a weld. This allows the aforementioned advantages to be realized, especially with regard to computer-aided design, e.g., also within the framework of modeling and simulation.

[0064] The aforementioned problem is also solved by a corrugated web beam construction according to the present disclosure, formed from at least one type of corrugated web beam, a single type of connecting piece, in particular in the configuration of a diagonal stiffener, and one or two types of crossbeams, in particular a first type of crossbeam in the configuration of a wide crossbeam and a second type of crossbeam in the configuration of a narrow crossbeam. This allows the aforementioned advantages to be realized, especially with regard to the positive effects already described here of the simple and robust construction with low component variation and good accessibility.

[0065] The width is understood to be the extent of the respective crossbeam connection (stiffness) in the intended arrangement relative to the corrugated web beam, i.e. in the transverse direction.

[0066] The aforementioned problem is also solved by a corrugated web beam material connection construction, created by steps according to a computer implementation as described in the present disclosure, in particular comprising the creation of at least one material connection provided in the intended connection area on the corrugated web, in particular a weld seam to ensure the material connection (indirect material connection) between the corrugated web and the crossbeam by means of the connecting piece. This allows the aforementioned advantages to be realized.

[0067] The aforementioned problem is also solved by a structurally load-bearing structure, created by steps according to a computer implementation as described in the present disclosure, wherein at least one corrugated web beam material-jointed structure is materially joined for the structurally load-bearing structure by means of at least one welding robot or similar manufacturing / assembly aid. This allows the aforementioned advantages to be realized, particularly with regard to the integration of the corrugated web beam material-jointed structure described here into more complex structurally load-bearing structures, especially building structures with comparatively large unsupported spans, such as roof structures of warehouses.

[0068] The aforementioned task is also solved by using a crossbeam, a crossbeam connection, or a cross-stiffening arrangement, each to provide a connecting piece (diagonal stiffener) to be bonded to a corrugated web beam, thus forming a corrugated web beam bonded structure. In this arrangement, the bond is ensured indirectly via the connecting piece to the corrugated web of the beam, and an end of the corresponding crossbeam oriented towards the corrugated web remains without direct contact with the web (i.e., interacts with the web only indirectly via the connecting piece). The connecting piece projects obliquely from the crossbeam at a predefined angle and extends beyond the end of the crossbeam towards the corrugated web. This allows the aforementioned advantages to be realized.

[0069] The aforementioned problem is also solved by using at least one corrugated web beam material connection structure according to the present disclosure based on two or three standardized stiffening elements, namely at least one type of crossbeam or crossbeam connection, in particular transverse stiffeners and one type of diagonal stiffener as a connecting piece, to form a structurally load-bearing structure by means of at least one crossbeam arrangement stiffening the corresponding corrugated web beam with a multi-leg stiffening designed for corrugated web material connection consisting of a crossbeam and connecting piece (longitudinally position-tolerant corrugated web material connection transverse connection), in particular to form a structural structure, e.g.A roof structure in which the corresponding corrugated web beam is structurally and load-bearing stiffened in at least one longitudinal position and on at least one of the two lateral sides of the corresponding corrugated web beam by at least one transverse stiffener in conjunction with a diagonal stiffener, i.e., by the corresponding crossbeam arrangement. This allows the aforementioned advantages to be realized.

[0070] It is understood that, based on the present disclosure, a person skilled in the art can conduct investigations and further developments to optimize, for example, the relative orientation, material thickness, and dimensioning of the components, support elements, and stiffening elements described herein. This includes, in particular, experimental investigations and / or computer-aided simulations or calculations to adapt a structure to predefined specific load conditions and / or to geometric features, such as the geometric profile of the web. In doing so, the person skilled in the art can also utilize common methods for computer-aided generation of options and / or for computer-aided identification of optimization potential. Specifically, within the scope of the present invention, a person skilled in the art is considered to be an engineer with several years of professional experience in the field of designing load-bearing structures, particularly those with large unsupported spans.

[0071] Summary: When joining corrugated web beams to other beams, especially crossbeams, using a material-bonded connection, comparatively high demands must be placed on the material bond. On the other hand, the geometric, especially wave-like, shape of the corrugated web imposes certain limitations, particularly regarding the practicality of assembly or joining in the field (at the installation site of the structurally load-bearing structure) during construction, especially due to the requirement of exact relative positioning (alignment of the connection partners relative to each other).A corrugated web beam construction comprising at least one corrugated web beam and at least one crossbeam arranged transversely, in particular orthogonally, to the longitudinal extent of the corrugated web beam is provided, wherein the corrugated web beam has a top chord and a bottom chord and a corrugated web extending between the chords, wherein the corrugated web beam and the crossbeam are connected to each other by a material bond, in particular welded, at least in the region of the corrugated web. According to the invention, the crossbeam has a connecting piece projecting obliquely from the crossbeam at a predefined angle and extending beyond the end of the crossbeam towards the corrugated web beam, by means of which the material bond can be provided, including two unequal angles relative to the longitudinal extent of the corrugated web beam.This allows for less restrictive boundary conditions in the relative positioning of the crossbeam relative to the corrugated web beam, and also ensures greater variability regarding the relative position of the material bond on the corrugated web. Furthermore, a higher degree of standardization of components can be used, resulting in cost savings. The invention also relates to a crossbeam designed for such a corrugated web beam material bond construction, the computer-aided implementation of a method for forming such a corrugated web beam material bond construction from the corrugated web beam and crossbeam and connecting piece or diagonal stiffener, as well as corresponding uses.

[0073] The invention will first be explained with general reference to all reference numerals and figures. Specific features or individual aspects, or aspects of the present invention that are clearly visible / representable in the respective figure, will be addressed individually in connection with the respective figure.

[0074] A corrugated web beam material connection structure 10 is provided, comprising at least one corrugated web beam 1 or its digital twin and at least one crossbeam 20 (in particular cross stiffeners S1, S2) or its digital twin, arranged or to be arranged transversely as intended, wherein the corrugated web beam 1 has a top chord 2 and a bottom chord 3 and a corrugated web 4 extending between the chords, wherein the corrugated web beam 1 is / will be materially connected to the crossbeam 20 at least in the area of ​​the corrugated web, in particular welded;wherein the crossbeam 20 is / is connected to a connecting piece 23 (in particular diagonal stiffener S3) which projects obliquely from the crossbeam at a predefined angle β and extends beyond the end of the crossbeam in the direction of the corrugated web beam, by means of which the material-bonded connection can be provided, in particular including two unequal angles each relative to the longitudinal extent of the corrugated web beam.

[0075] The crossbeam(s) 20, S1, S2 (hereinafter also generally referred to as crossbeam connection) can optionally be provided within the outer flange edges 1.1 of the corrugated web beam or extend beyond them in the transverse direction (y). The corrugated web beam material connection assembly 10 comprises at least one connecting piece 23, S3, which engages the surface 5 of the corrugated web in a material-bonded manner or forms material-bonded joining partners together with the corrugated web. Optionally, at least one crossbeam, in particular a transverse stiffener S1, can engage directly the surface 5 of the corrugated web in a material-bonded manner, in particular at a vertex of the corrugated web. The section of the corrugated web that is intended for material bonding with the connecting piece can be described / designated as an obliquely extending butt surface section 8.

[0076] Advantageously, the crossbeams comprise both a first type of crossbeam 20a or crossbeam connection (stiffener element or beam component), in particular a wide (large, long) cross stiffener S1, and a second type of crossbeam 20b or crossbeam connection (stiffener element or beam component), in particular a narrow (short) cross stiffener S2. This facilitates even more practical structural integration at more or less arbitrary relative longitudinal positions along the corrugated web, with minimized component variation.

[0077] The end 21 of the crossbeam, which is intended to face the corrugated web, preferably has an inclined end face 22, wherein the angle of the inclined surface relative to the longitudinal direction X1 of the corrugated web advantageously corresponds at least approximately to the angle of projection. Particularly with comparatively thick crossbeams, this can also ensure additional stability or strength.

[0078] In this context, the connecting piece can also be referred to as a third type of stiffening element 23 (beam component), in particular as an obliquely projecting / protruding connecting piece (diagonal stiffener), advantageously with a projection angle corresponding to the angle of the inclined surface on the end face of the corresponding crossbeam.

[0079] The end face 24 at the free end of the connector, which is intended to be connected to the corrugated web, can have at least one end face oriented at a predefined angle, optionally a first, relatively larger end face 24a and a second, relatively smaller end face at a different angle or in the form of a raised section. For the sake of simplicity, one can speak of a first and second end face 24a, 24b on the end face of the connector. An opposite (possibly free) end 25 of the connector can remain as a free end.

[0080] Those also in the characters, especially Fig. 4, Fig. The material-bonded connection 30 (connection point, connection line, and / or connection surface) described in section 5 on the corrugated web (i.e., to the connector or directly to the crossbeam) can comprise a first weld 31 and a second weld 32, and the material-bonded connection 40 between the crossbeam (transverse stiffener) and the connector (diagonal stiffener) can also comprise a first weld 41 and a second weld 42 (as in Fig. 4 indicated). Crossbeam and connecting piece together form a crossbeam arrangement 50.

[0081] The respective crossbeam (or the corresponding cross stiffener) is arranged, for example, with reference to the requirement of a flush finish on the outer edge of the flange, and thanks to the transverse offset that can be compensated for by means of the connecting piece (diagonal stiffener), the relative longitudinal position Pxv (x-coordinate) can remain variable, i.e., a variable longitudinal position for arranging a respective crossbeam along the corrugated web.

[0082] To describe the relative position or orientation of the connector or diagonal stiffener and the corrugated web and the longitudinal axis X1 of the corrugated web beam, the following angular references can generally be distinguished, particularly in the connection area A30 or in the respective welding zone (each in a top view in the z-direction): ε1 first angle enclosed by the connector and the corrugated web in the connection area, in particular an acute angle; ε2 second angle enclosed by the connector and the corrugated web in the connection area, in particular an obtuse angle; γ1 first angle between the connector and the longitudinal extent of the corrugated web beam; γ2 second angle between the connector and the longitudinal extent of the corrugated web beam.

[0083] The present invention is explained in particular with reference to the relative longitudinal positions of the crossbeams (transverse stiffeners) corresponding to a vertex (longitudinal position corresponding to a vertex of the profile), a trough / valley point (longitudinal position corresponding to a valley point of the profile), or an inflection point (longitudinal position corresponding to an inflection point of the profile). However, it should be understood that the crossbeams (transverse stiffeners) can also be arranged in other / further relative longitudinal positions relative to the profile of the web. In this respect, the technical teaching of the present invention is not limited to the beam combinations and relative positions described in detail. The spatial directions x, y, z are designated with reference to the longitudinal extent of the corrugated web beam (longitudinal, transverse, vertical, or perpendicular, respectively) and are thus aligned in a relative coordinate system according to the longitudinal orientation of the corrugated web beam.

[0084] The creation of the corrugated web beam material connection structure can therefore be roughly subdivided into the following steps: Step V0: Providing a corrugated web beam for forming a corrugated web beam material connection structure; Step V1: Providing interconnected crossbeams and connectors, or connecting crossbeams and connectors; Steps V2, V2a: Indirectly connecting the corrugated web and crossbeam by means of the connector; Step V2b: Directly connecting the corrugated web and crossbeam material-bonded; Step V3: Providing at least one further material-bonded connection. It should be understood that the sequence of the steps described here does not necessarily have to follow the chronological order of the numbering chosen. For example,First, a material bond is formed between the corrugated web and the connecting piece / diagonal stiffener, before a material bond is formed between the connecting piece / diagonal stiffener and the crossbeam / cross stiffener.

[0085] The following quantities, key figures, or parameters essentially relate to a mathematically based design of the material connections described here. They may therefore depend on the type of material connection and are thus to be understood as examples. They can be used to define a standardized / standardizable design or construction, for example, in the context of a computer program for controlling a welding robot and / or for specifying steps for the welding process. Therefore, they are not necessarily all found in the drawings, but are at least found in the mathematical formulas discussed here. a seam width, especially fillet weld width a3 Wave height or wave height, e.g. 40mm or 43mm a 3,r Resulting wave height at the mid-surface of the bridge b s1 , b s2 Longitudinal extent / length dimension of the respective crossbeam (when properly aligned in the y-direction), corresponding to the width of the transverse stiffener S1 or S2. b s3 Longitudinal extent / length dimension of the diagonal stiffener S3, also referred to here uniformly as width b Gap width at the web for the (direct) connection with the S3 stiffener b f Flange width c Exaggeration d a seam thickness d s1 , d s2 , d s3 Sheet thickness / material thickness of S1 or S2 as well as of S3 f r resulting wave amplitude h s1 , h s2 , h s3 Height of S1 or S2 and of S3 h w Bridge height l a seam length l x1 Length section along profile for preferred first combination of stiffening elements l x2 Length section along profile for preferred second combination of stiffening elements t", web thickness w Half-wavelength (length between wave crest and wave trough), e.g. approx. 77.5 mm, advantageously considered here as a geometric reference dimension for the positioning of stiffeners, welds and / or connecting elements. α outer seam angle, pointing laterally outwards between transverse stiffener and diagonal stiffener β inner seam angle, in particular seam angle of the transverse stiffener at the end face or predefined (acute) offset angle not equal to 0 and not equal to 90° relative to the longitudinal extent of the cross member (relative to the width direction or transverse direction) β22 Angle of the oblique end face, e.g. corresponding to the angle of retraction δ Seam angle of the joint (inner seam angle of the connector or the S3 stiffener)

[0086] The following section explains special features of the invention with reference to individual figures or embodiments.

[0087] In Fig. Figure 1 illustrates a variant of a relative arrangement of support components (crossbeams, stiffeners, connecting piece) according to exemplary embodiments of the invention, in which each crossbeam can be arranged variably in the relative longitudinal position Pxv relative to the profile (in particular corrugated profile) of the web 4 in a comparatively simple manner. The variable longitudinal position Pxv illustrates the possibilities for variation in the relative positioning of the crossbeams created by the present design concept.

[0088] In Fig. Figure 2 shows a structure 100 (in particular a structural load-bearing structure, especially a building structure, e.g., a roof structure) comprising a plurality of crossbeams 20 or S in different longitudinal positions, wherein the crossbeams 20 can optionally be designed as beam components or stiffening elements that terminate flush with the outer flange edge of the corrugated web beam 1, or as beam components or stiffening elements that project beyond the outer flange edge. If a flush termination is provided, e.g., by means of crossbeam type S1 or S2, a further beam component can connect to it in the transverse direction (not explicitly shown here). In this respect, the following describes Fig. 2 is also an example of a modular design for a corrugated web girder construction, which can be easily scaled in size and / or number. In Fig. 2 The more or less wavy course of the wave web (4) is not explicitly shown for better clarity, but is only referenced by reference to the longitudinal axis X1.

[0089] In Fig. Figure 3 shows a welding robot or similar manufacturing / assembly aid 60 set up for creating material connections, which may also be equipped with a control / regulation unit and a communication module.

[0090] For example, the assembly aid 60 is controlled and operated via the computer program described elsewhere, whereby a user interface for setting / specifying parameters, values, sizes, and amounts can also be provided via an app or similar on a monitor or end device. The indicated constructive plane or connection plane Exyz signifies that the angled connection through the connector or the diagonal stiffener leads to a force transmission plane, which, in the coordinate system used here, is represented in all three, e.g., Fig. 2 and Fig. 4 indicated spatial directions (x, y, z), thus neither exactly in the longitudinal direction x nor exactly in the transverse direction y, preferably at a uniform predefined angle β (see Fig. 2).

[0091] With reference to Fig. 3. The following can also be noted: The larger the (acute) angle at the end face of the corresponding transverse stiffener or crossbeam, the smaller the inclination of the diagonal stiffener or connecting piece S3 relative to the contact surface on the web (joining area in the corresponding longitudinal section). This also facilitates the welding process between the joining partners S3 and web; in addition, the required length of S3 for the connection between the transverse stiffener and web can be kept as short as possible. At the same time, a very steep inclination (strong tilting) of S3 leads to very small angles between the edges of S1 / S2 on the one hand and S3 on the other, which would significantly impede access, e.g., for a welding nozzle, and which, on the other side of the transverse stiffener, i.e., with too large an outer angle, could lead to inadequate weld seam guidance. In this context, it has now been determined that an outer seam angle between 70° and 110° between S1 and S3 is optimal.The angle between S2 and S3 (resulting in an internal angle of 20° at the end face of S1 / S2) is considered optimal (i.e., a weld angle at a fabric-bonded joint accessible laterally from the outside at the connection point between S2 and S3, where 110° is the secondary angle of 70°). The internal angle at the end face of S1 / S2 (S1 and S2) directly influences the effective steel area: the larger the angle, the shorter S2 becomes, and the smaller the steel area of ​​both transverse stiffener elements. For the joining partners S3 and web, the butt weld in a T-joint configuration with a high-strength joint represents a high-quality weld connection, at least as far as the embodiment described in detail here is concerned. A weld angle of 35° in combination with a so-called camber (butt / joint surface next to chamfer) of 2 mm at the connection point has proven optimal, particularly with regard to accessibility.Depending on the application, the angle can vary between 35° and 60°. The smaller the angle, the fewer conflicts arise with the adjacent weld joint to the transverse stiffener S1 / S2, and the shorter the component S3 can be dimensioned for the connection to the web surface.

[0092] In Fig. Figure 4 shows a variant of a combination of the support components described here for a relative longitudinal position, in which both crossbeams are arranged in the region of a peak or trough of the wave-like profile. Particularly with the dimensioning of the support components described here, one type of crossbeam, S1, can be elegantly connected directly to the wave web (the joining therefore takes place in the section 7 of the wave web, which runs at least approximately parallel or in the longitudinal direction), and simultaneously with a flush finish at the corresponding outer edge of the flange, while the other type of crossbeam, S2, interacts with the intermediate connecting piece 23, S3. For the sake of clarity, in Fig. 4. The individual material connections or connection areas are also provided with reference numerals 30, 31, 32 and 40, 41, 42.

[0093] In Fig. Figure 5 shows a variant of a combination of the support components described here for a relative longitudinal position, in which both crossbeams are arranged in the region of an inflection point (at least approximately) of the wave-like profile, so that the crossbeams (here type S1, S2) are each intermediately connected together with the connecting piece 23 (here diagonal stiffener 23) to the wave web in the corresponding butt surface section 8 provided for the material-fit connection. It is worth mentioning that a typical angle between the wave web longitudinal axis X1 and the wave web profile in the inflection point region, i.e. usually at the geometric intersection with the wave web longitudinal axis, lies in the range of 35 to 38°, i.e., approximately or exactly 36°. Fig. 1 and Fig. Furthermore, drain openings 26 are indicated in Figure 5, which are important for certain steel grades or tempering or post-treatment steps and may also be significant with regard to the positioning of the material bonding described here and are taken into account within the scope of the present invention. Fig. Figure 5 also indicates the seam angle δ of the joint (inner seam angle of the connector or the S3 stiffener), as well as an outer seam angle α of the S1 and S3 stiffeners, i.e. the outward-facing angle formed between the cross stiffener / crossbeam and the connector, which is, for example, in the range of 65 to 75°.

[0094] In Fig. Figure 6 illustrates the different longitudinal sections along a wavelength of a particularly sinusoidal wave profile, in each of which a preferred combination of support components according to the present disclosure can be provided. For example, a design specification can be made based on this, i.e., a specification for the use of certain combinations of support or stiffener components depending on a relative longitudinal position. Such a specification can also be given, for example, to a welding robot, especially if different types of welds are to be provided for the individual weld joints and / or if, for example, different material thicknesses of the joining partners are significant.

[0095] In Fig. Figure 7 illustrates advantageous profiles for the beam components considered in detail here (crossbeams or cross stiffeners 20, S, S1, S2 and connecting pieces or diagonal stiffeners 23, S3). Beam component S3 tends to have a thinner material than the corresponding crossbeam type S1, S2.

[0096] In the Fig. Figure 8 illustrates fillet welds and the relative arrangement of the connection / joining partners relative to each other, with reference to an exemplary longitudinal position in which crossbeams and connecting pieces are provided in combination on both flange sides of the corrugated web beam.

[0097] In the Fig. Figure 9 illustrates fillet welds and the relative arrangement of the connection / joining partners relative to each other, with reference to an exemplary longitudinal position in which crossbeams and connecting pieces are provided in combination on only one of the flange sides of the corrugated web beam, and on the other flange side only a crossbeam is provided, here crossbeam type S1, i.e. without an intermediate connecting piece or a diagonal stiffener.

[0098] In the Fig. Section 10 explains further geometric details. Fig. Section 10A explains the relationship between the inner and outer seam angles using the example of the crossbeam 20a of the first type. Fig. Section 10B explains the relationship between the inner and outer weld angles and the flank angle with reference to the connecting piece 23. For the sake of completeness, it can be repeated here as well: The angle α denotes the outer weld angle between the transverse stiffener and the diagonal stiffener, and has a particularly strong effect on welding accessibility. With an advantageous outer weld angle of, for example, α = 70°, an inner flank angle of β = 20° results at the end face of the transverse stiffener (based on 90° - 70° = 20°). This angle β corresponds to the inner weld angle β. s1 / s2 at the end face of the respective transverse stiffener 20, 20a, 20b or S1, S2. The term "outer" refers to the outer weld angle α between the components, while "inner" describes the resulting inner flank angle β at the end face of the transverse stiffener. The in Fig. The indicated seam angle δ of the flank of the connecting piece S3, as shown in 10B, can also be considered an internal angle β.s3 be designated.

[0099] In Fig. 11 illustrates steps of a method for forming a corrugated web beam material connection structure according to the present disclosure, in particular for structural constructions, wherein the corrugated web beam material connection structure is formed from at least one corrugated web beam and at least one crossbeam arranged transversely, in particular orthogonally to the longitudinal extent of the corrugated web beam, wherein the corrugated web beam is brought into material connection with the at least one crossbeam at least in the area of ​​the corrugated web of the corrugated web beam, preferably by a welded connection;wherein the at least one crossbeam is / is connected to a connecting piece (here also referred to as a diagonal stiffener) projecting obliquely from the crossbeam at a predefined angle of deflection other than 0° and other than 90° and extending beyond the end of the crossbeam in the direction of the corrugated web beam, wherein the method comprises: a step of forming the corrugated web beam material connection structure by bringing the corrugated web beam into contact with the crossbeam in at least one longitudinal position of the corrugated web beam by indirectly connecting the crossbeam and the corrugated web beam by material-bonding connection of the connecting piece and the corrugated web beam (by at least one material-bonding connection) in the area of ​​the corrugated web. The method can also be / be subdivided into the following steps:; Step V0 Providing a corrugated web beam to form a corrugated web beam material connection structure comprising at least one crossbeam or a comparable crossbeam component or cross stiffener, in particular with the corrugated web beam in the desired length and cross-sectional dimensions and cross-sectional profile for the corresponding structural load-bearing structure, in particular building structure; Step V1: Providing interconnected crossbeams and connectors, or connecting crossbeams and connectors, each for the intended cross-connection (transverse connection) to the corrugated web; Step V2, V2a indirect connection of corrugated web and crossbeam by means of the connecting piece, by material-bonded connection of corrugated web and connecting piece (material-bonded cross connection); Step V2, V2b immediate, direct material-bonded connection of corrugated web and (further) crossbeam, in particular crossbeam of a / the first type (material-bonded cross connection); Step V3: Provide at least one further material-bonded connection, in particular in the area of ​​a height connection (material-bonded height connection) and / or in the area of ​​a further (butt) connection further laterally spaced in the transverse direction from the corrugated web beam.

[0100] In particular, following step V3, further steps may be provided (especially at the installation site in the field), e.g. a transverse connection by means of further crossbeam components, either via form-fit / force-fit coupling mounting flanges, or by means of at least one further material connection.

[0101] It should be understood that at least step V1, and optionally also step V2 (V2a and / or V2b), can also be designed as a preparatory assembly step that does not necessarily have to be carried out at the installation site. Therefore, the steps described here can, for example, also be carried out as part of providing the corrugated web beam for a specific installation, be it in the form of purely structural stiffening / stiffening, be it as a preparatory measure for providing a crossbeam connection that, for example, projects transversely beyond the flange edges and also offers further connection options, be it through form-fit / force-fit coupling mounting flanges, or be it through material-bonding connection surfaces provided for at least one joining partner.

[0102] The steps described here deliberately do not explicitly address the manufacturing of the corrugated web beam itself, particularly since the invention allows the use of standardized corrugated web beams for the construction of the corrugated web beam described here. In other words, manufacturing processes for producing the corrugated web beam itself are known to those skilled in the art and can also be considered a step preceding step V0 in the value chain under consideration here.

[0103] The in Fig. The 11 diamond-shaped fields indicated between the individual steps illustrate possibilities for a person skilled in the art to influence the process or the sequence of steps, in particular by evaluating sensor data or process parameters and taking them into account in the process engineering planning or control / regulation. For example, steps V2a and V2b are carried out by a welding robot or similar manufacturing / assembly aid set up for material bonding, to which a specific relative longitudinal position is given, so that the welding robot can place, execute, and shape the respective material bond according to control / regulation specifications, which are generated, for example, by the computer program described here.The specifications for such a welding robot can, in particular, include a movement path for at least one tool component and / or the entire welding robot, e.g., repositioning according to longitudinal position specifications. For example, the welding robot is mounted on the corrugated web beam and can move along it (in the longitudinal direction).

[0104] The following describes general embodiment(s) according to the invention, starting from the basic concept of the invention and with reference to different variants of the relative arrangement of the connecting piece and the crossbeam component, each characterized by the use of a maximum of three different beam components or stiffener elements. Where reference is made to the term stiffener or transverse stiffener, it is to be understood synonymously as a reference to a crossbeam or a crossbeam component or crossbeam connection. For corrugated web beams, the invention provides in particular a lateral transverse stiffener arrangement with a diagonal stiffener (connecting piece) (at least one transverse stiffener in conjunction with a diagonal stiffener), in which three standardized stiffener elements are modularly arranged along the wavelength of the corrugated web (or...in the corresponding longitudinal position) can be combined with each other, for example only two of them: a first type of crossbeam component or stiffener S1 in the design as a wide crossbeam stiffener (or crossbeam connection), and / or a second type of crossbeam component or stiffener S2 in the design as a small crossbeam stiffener (or crossbeam connection), as well as a third type of beam component or stiffener S3 in the design as a diagonal stiffener (connecting piece).

[0105] The stiffening elements (beam components) provided for bracing and connection in the transverse direction are preferably used in defined / predefinable arrangement zones along the profiled or wave-like (e.g., sinusoidal) web of the corresponding corrugated web beam, in particular I-beams (or equivalent beam types such as I-beams). According to the invention, all geometric variations of the distance between the web and the outer flange edge can advantageously be covered by combining these three standard components (or by combining both the first type of stiffener with the standardized diagonal stiffener and the second type of stiffener with the standardized diagonal stiffener), each for specific dimensions of a respective type of corrugated web beam. It should be understood that the first and second types of stiffeners (S1, S2) are also dimensioned differently with regard to the requirement of a flush termination at both outer flange edges.can be designed so that, if the requirement for a flush finish is eliminated, only one type of stiffener in combination with the standardized diagonal stiffener may be sufficient to realize the concept according to the invention.

[0106] It is understood that preferably three standardized stiffener elements are provided, with only two being used per longitudinal position, depending on at which longitudinal positions of the corrugated web a transverse connection is to be made. In certain longitudinal sections, a combination of transverse stiffeners and diagonal stiffeners on both sides of the beam is recommended, while in other areas the combination of two of the stiffener types should only be implemented on one side.

[0107] For example, the transverse stiffeners (or their central longitudinal axis) are arranged in inflection point regions of the wave-like web profile. In the region of the inflection points of the profiled or wave-like (e.g., sinusoidal) web contour, particularly at a longitudinal position where the web cross-sectional contour intersects the central longitudinal axis of the wave web beam, the geometric conditions can prove to be particularly unfavorable. The invention makes it possible to use four stiffener elements there (at the corresponding longitudinal position) (two on each lateral side), in particular a combination of S1 and S3 and a combination of S2 and S3 (as in Fig. (illustrated in Figure 4), where S1 and S2 advantageously connect flush to the outer edge of the flange, and where S3 forms the connection to the web. This allows the varying distances resulting from the profiling to be completely bridged. This is also illustrated in particular in Figure 4. Fig. 4. Accordingly, it can be flexibly decided whether and in what way a further transverse connection should be made laterally across the flange dimensions, whereby a connection to the top and / or bottom flange is also optionally possible. The in Fig. 4 The indicated end face at the end of the S1 stiffener facing the corrugated web can also run at an oblique angle in the opposite direction to that shown. Fig. Figure 4 also shows the coordinate system x, y, z indicated here relative to the longitudinal extent X1 of the corrugated web beam, where the z-axis corresponds to the height direction also referenced here with the reference symbol h in size / magnitude specifications.

[0108] For example, the cross stiffeners (or their central longitudinal axis) are arranged in the area of ​​the wave crest and wave trough of the wave-like web profile (at one or more longitudinal positions).

[0109] In the area of ​​the wave crest and wave trough – on the side where the distance between the web and the outer edge of the flange is minimal (narrowest width) – a transverse stiffener can be directly connected to the web according to the invention (as in Fig. (illustrated in Figure 5). In this area, therefore, only three stiffening elements are provided (at the corresponding longitudinal position): stiffener S1 in direct connection with the web and flush with the outer flange edge, and a combination of stiffeners S2 and S3. Near the apex or invert point, S1 can be directly connected to the web, thus reducing the number of required S3 elements. This is further illustrated in Figure 5. Fig. 5.

[0110] As the distance from the apex or trough point increases, the connection position (relative connection point for defining the transverse and longitudinal offset) of S3 shifts relative to S1 and S2 (the distance to be bridged by the connecting piece between the crossbeam and the corrugated web becomes larger or smaller), and thus the butt surface section 8 on the corrugated web, intended for the material-fit connection, also shifts. This is in Fig. 5 indicated by the longitudinally oriented double arrow Pxv. According to the present invention, the modular combination of the three components or stiffener elements allows for the implementation of a suitable, geometrically feasible, and weldable stiffener arrangement for each position along the wavelength (or in the corresponding longitudinal position), advantageously based on only two or three different stiffener elements (a maximum of two types of crossbeams and only one type of connecting piece).

[0111] The following designations, input parameters and sizes can be proposed to describe the dimensioning of the stiffening elements proposed here, as well as for the geometric and structural design: b s1 , b s2 , b s3 Width (length dimension) of the transverse stiffener S1 or S2 and the diagonal stiffener S3 h s1 , h s2 , h s3 Height of the transverse stiffener S1 or S2 and the diagonal stiffener S3 d s1 , d s2 , d s3 Sheet thickness / material thickness of the transverse stiffener S1 or S2 and the diagonal stiffener S3 b f Flange width h w Bridge height a3 Wave height d a seam thickness

[0112] It should be understood that the terms weld thickness and fillet weld width refer to the same geometric parameter of the corresponding weld, in particular fillet weld, and are also used synonymously in practice.

[0113] The following section describes in more detail a dimensioning of the transverse stiffener S1 that is advantageously provided according to the invention. The transverse stiffener S1 is advantageously dimensioned such that, in the most unfavorable installation position, it can completely bridge the entire distance from the highest point of the wave trough or wave crest geometry to the outer edge of the flange. A preferred standard width b s1 Therefore, depending on the flange width b f and the wave height a3 of the respective carrier type is determined as follows: b s1 = 0.5b f - 0.5a3

[0114] Since the transverse stiffener S1 is advantageously designed with an inner weld angle β of 20° to the outer edge of the flange (alternatively deviating by a few degrees), the width b refers to s1 on the distance to the tip of the stiffener (i.e., not on an orthogonal axial dimension).

[0115] The following section explains in more detail an advantageous dimensioning of the transverse stiffener S2 according to the invention. To meet the requirement of minimizing the number of different stiffening components, the second transverse stiffener S2 is preferably shorter than S1. It is also important to determine how short this stiffener element can / should be dimensioned to ensure a standard-compliant welded connection on the web in combination with the diagonal stiffener S3. From a static point of view, a greater width (extension in the intended transverse direction) is generally advantageous. Therefore, S2 should be as wide as possible – without compromising the feasibility of the design or the accessibility for welding. Based on the previously determined width of S1, the invention yields key influencing factors that determine the ideal width b. s2The following should be taken into account: b s1 Width of the transverse stiffener element S1 b Gap width at the web for the connection with the S3 stiffener l a Seam length (l a = d a / cos45°) d s3 Thickness of the diagonal stiffener β Seam angle of the transverse stiffener

[0116] From these parameters, the following formula can be derived to determine the maximum possible width b. s2 the S2 cross-brace: bs2=bs1−(b+la∗sinβ+ds3cosβ)

[0117] The following section describes in more detail an advantageous dimensioning of the diagonal stiffener S3 according to the invention. The diagonal stiffener S3 advantageously has the same geometry for all installation positions, thus being standardized as a single type. It connects either S1 or S2 to the web. The width b s3The diagonal stiffener S3 (corresponding to its dimensions or length in the intended oblique main extension direction of the diagonal stiffener) is defined based on the most unfavorable application case, i.e., based on the largest possible required offset. The resulting minimum width b s3 The diagonal stiffness in the example described here, i.e. for the dimensions of the corrugated web beam considered here, is preferably b s3 = 75mm (here, therefore, in terms of magnitude, slightly less than half the flange width of the corrugated web beam), so that a safe force transmission and sufficient weld lengths can be ensured for each of the possible / required relative positions of the diagonal stiffener in an intermediate arrangement between the corrugated web and the crossbeam / cross stiffener.

[0118] Specifications can also be made for the sheet thicknesses that are advantageous for the design, which facilitate the implementation of the present invention. With a tapered joint shape at the weld point from S1 to the web, this may limit the maximum permissible gap width (b), particularly according to DIN EN ISO 9692-1. The permissible, or in this case optimal, gap width can determine the relative position of the joining partners relative to each other. To ensure weldability, an upper limit for the permissible thickness of S1 in the area of ​​the wave crest and trough can be derived from this. To determine this limit, it can be calculated, using a sinusoidal profile of the corrugated web as an example, what displacement occurs on the x-axis of the sine curve (or any other wave-like profile) when its shape changes by b [mm] or by the gap width in the y-direction.For this purpose, the sine function underlying the sinusoidal curve can be mathematically derived and transformed into the following equation:. dx,s1=wπ∗arccos((fr−b)∗2a3,r)

[0119] The following terms are used: a 3,r Resultant height (peak-trough value) of the wave in the mean surface of the bridge (a 3,r = a3 - t w ) t w Bridge thickness (material thickness of the bridge) f r Resultant wave amplitude / wave amplitude f = 0.5*a 3,r b Gap width at the web for direct connection with S1 stiffener w Half-wavelength (half the wavelength or half the length of the period / phase)

[0120] Since the equation for d x,s1 Referring to the course of one side of the sine curve in the valley or mountain area, it can be deduced that the maximum structural thickness of the stiffener S1 must not exceed the following value: d s1,k= 2* d x,s1

[0121] To limit the number of different sheet thicknesses, the maximum structural thickness of the stiffener S2 can advantageously be set to the same value: d s1,k = d s2,k

[0122] In particular, according to the normative regulations of the respective chosen welding technique, the thickness of the diagonal stiffener S3 may / should be at least 3 mm: 3.0 ≤ d s3,k For example, the following is specified as a constructive boundary condition: 3.0 ≤ d s3,k ≤ 10.0mm For example, the sheet thickness for the diagonal stiffener S3 is set to half the sheet thickness of the stiffeners S1, S2, here 5mm as an example.

[0123] It should be understood that the gap widths do not necessarily have to be the same size; for example, a gap between S1 and the bridge should be a maximum of 2mm; however, a gap between S3 and the bridge can be up to 4mm.

[0124] Specifications can also be made for the structurally advantageous stiffener heights and for drainage openings (compare corrosion protection requirements), which facilitate the implementation of the present invention. The heights of the transverse stiffeners S1 and S2 are essentially determined by the web height (h). w ) adapted; they preferably extend over the full web height between the upper flange (or upper chord) and the lower flange (or lower chord). The height of the diagonal stiffener S3 is advantageously increased by 25 mm on both the upper and lower sides relative to the web height (h). w ) reduced, particularly to meet the requirements of the hot-dip galvanizing and coating process. This measure has proven to ensure an unimpeded flow and drainage of zinc and / or coating material.

[0125] Advantageously, two drain openings with a defined diameter are provided on the stiffening elements S1, particularly in accordance with DIN EN ISO 14713-2. The diameter of these openings depends on the respective static sheet thickness of the S1 or S2 stiffening element. The inner edge of each side of the S1 element is advantageously provided with a 45° bevel cut to easily avoid collisions with the welds of the corrugated web beam. The aforementioned structurally advantageous boundary conditions can be further explained, in particular, with reference to Fig. 7 will be illustrated.

[0126] With regard to welding accessibility, welding-related boundary conditions, and welding feasibility, the invention can also address the following points in particular. The solution according to the invention described herein can be advantageously implemented for the welding processes manual arc welding (MMAW) and gas metal arc welding (GMAW), especially metal active gas welding (MAG), particularly since these welding processes are considered particularly well-established in connection with the production of corrugated web beams. To ensure welding accessibility in all arrangement zones, the stiffening elements according to the present disclosure are preferably designed such that all standard-compliant welding parameters can be maintained. These include, in particular, the selection of suitable weld types, the design of butt and joint shapes, and adherence to permissible dimensional tolerances.

[0127] The stiffeners are advantageously designed to ensure that all welds remain easily accessible and a reproducible, series-production-ready manufacturing process is guaranteed. This includes both T-joint connections, preferably between transverse and diagonal stiffeners, and the connection of the diagonal stiffeners to the web. To achieve the most structurally advantageous stiffener design, the welding parameters can be selected as follows, particularly with regard to DIN EN ISO 9692-1, illustrated here using specific welding techniques as examples. For instance, a T-joint fillet weld with an end-face joint can be particularly advantageous between the crossbeam and web, and between the crossbeam and the connecting piece.It has been shown that an optimal weld preparation between the stiffening elements described here, transverse stiffeners S1 / S2 and diagonal stiffeners S3 (i.e., between the joining partners crossbeam and connector), is designed without a gap, without camber, and with the largest possible acute angle between stiffeners S1 / S2 and S3. For example, a butt weld in a T-joint configuration with a high-strength joint shape can be particularly advantageous between the connector (diagonal stiffener) and the web.

[0128] Advantageously, standard-compliant welding parameters, such as weld type, joint and joint shape, and dimensional tolerances, are defined and taken into account in the design specifications according to the present invention. This is because the weldability of a component is influenced not only by its design and the material used, but also by the chosen welding process. With regard to the DIN EN ISO 9692-1 standard and the most stable welding process possible, recommendations for weld design and preparation measures can be given, particularly for the welding processes considered within the scope of the present invention: manual metal arc welding (MMAW), metal arc welding (MAG), gas welding, tungsten inert gas (TIG) welding, and beam welding. In principle, all common steel grades can be used, provided that the weld preparations are carried out as standardized as possible under practical conditions.For the structural design of the welds, the following aspects are particularly relevant, also in the context of any computer-aided dimensioning, especially of transverse and diagonal stiffeners: suitable weld type (butt or fillet welds), joint types (butt, T, or corner joints), joint shape (e.g., V-, X-, or K-joints), required or optimal weld angles (α, β), width, height, and tolerance dimensions of the weld preparation. It should be noted that weld types with HU and DHU joints appear to be less suitable for the applications described here.

[0129] Within the scope of the present invention, it has been shown that the welding parameters for achieving the most cost-effective stiffener design can be selected as follows, particularly for the sake of good accessibility: The weld joint of the diagonal stiffener S3 with the corrugated web is preferably designed as a butt weld in a T-joint configuration with a high-strength joint (with a high-strength joint, only about half the angle of a V-joint is present, especially since only one of the joining partners is chamfered). The intended gap between the stiffener S3 and the web is advantageously b = 2 mm and should not exceed a maximum of 4 mm. The camber of the stiffener S3 is preferably c s3 = 2 mm defined. The seam angle of the joint is preferably δ or β. s3 = 35°.

[0130] The diagonal stiffener S3 is preferably connected to the transverse stiffeners S1 and S2 via fillet welds in a T-joint configuration with a right-angled joint shape at the end face, without a gap between the stiffeners. The outer weld angle of stiffener S1 and S2 is preferably α. s1 / s2 = 70°, and an internal seam angle in the stiffeners S1 and S2 is preferably β s1 / s2 = 20° (see also Fig. 10A, Fig. 10B). The outer seam angle is to be understood as an angle between the stiffener components to be joined, and the inner seam angle is to be understood as an angle formed at the end face of the corresponding transverse stiffener.

[0131] The direct connection of the transverse stiffeners to the web can also be advantageously achieved using fillet welds with identical joint and butt joint designs. The gap between the stiffeners (S1 or S2) and the web should preferably be a maximum of b s1 / s2 = 2mm.

[0132] These welding parameters also enable, in particular, an economically and structurally advantageous dimensioning of all stiffening elements as well as a reproducible, series-production-ready manufacturing process of the stiffening elements.

[0133] The design method described here for the structural load-bearing components of the corrugated web girder construction also allows, in principle, the use of almost all other types of weld preparation as well as differing dimensions of the corresponding welding parameters. The variants described here in particular can ensure an economically and structurally advantageous design of the dimensions of the structural load-bearing components.

[0134] Particularly for welding techniques for T-joint designs, the following is advantageously advantageous for a fillet weld for connections between crossbeam S1 and corrugated web and between S1 or S2 and connecting piece S3, each for a gap width b = 2.0 mm, and for the outer weld angle of the S1 and S3 stiffeners, i.e., for the angle formed between the crossbeam / crossbeam and the connecting piece and pointing laterally outwards, α = 70° applies, and accordingly, for the inner weld angle β for the connection to the corrugated web, i.e., for the angle formed at the end face of the corresponding stiffener element, β = 20° can be used.

[0135] The reference symbol 'a' can generally be used here to refer to the seam width.

[0136] For a butt weld with HV joint, the following is advantageous for the connection between S3 and web: gap width b = 2.0 mm, so-called camber c = 2.0 mm, and the inner weld angle of the S3 stiffener, i.e., the weld angle of the joint δ = 35° (weld angle at the end face or end face of the diagonal stiffener, for the connection to the corrugated web).

[0137] Further arrangement principles provided according to the present invention along the wavelength or with respect to certain relative longitudinal positions are explained below. In the region of the inflection points, four stiffener elements are preferably used, namely two transverse stiffeners (S1, S2) and two diagonal stiffeners (S3). Near the wave crest and trough, however, three stiffener elements are sufficient, since the direct connection of the shorter transverse stiffener S2 to the web can assume a connecting function corresponding to a diagonal stiffener in this area. This arrangement principle fully covers all installation positions while simultaneously minimizing the number of different components or stiffener elements. This results in the following: Fig. 6 illustrated combinations for the different diagonal stiffener arrangements along a wavelength, also described here in general terms, whereby the reference to the stiffener types S1, S2, S3 is to be understood synonymously as a general reference to the different crossbeam types and the connecting piece: In particular with reference to Fig. 6. The following can be determined: In relative longitudinal positions corresponding to the wave crest and wave trough, i.e., in the areas with a smaller transverse distance between the web and the outer flange edge, S1 stiffeners are preferably used exclusively. On the opposite side of the web, transverse stiffeners of type S2 in combination with diagonal stiffeners of type S3 are preferably used in the same areas. The length of this section results from the maximum permissible structural installation thickness plus the actual statically effective thickness of the transverse stiffener S1. This area can be determined as follows: l x1 = d s1,k + d s1

[0138] Following this – up to the inflection point – is a section in which the combination of S2 and S3 is preferably used. The corresponding counter-combination on the opposite side preferably consists of S1 and S3. The length of this section is: l x2 = 0.5w - 0.5 lx1

[0139] The same principle applies advantageously to the area from the turning point to the next valley or vertex, but in a mirrored arrangement. Fig. Figure 6 illustrates this concept of the preferred geometric arrangement of the stiffening elements along a wavelength. In the Fig. In the arrangement zones marked by the underlined reference numeral S1, the use of the S1 stiffener (or one / the first corresponding crossbeam type) is preferred, either individually or in combination with the S3 diagonal stiffener (connecting piece). On the opposite side, the S2 transverse stiffener is preferably used together with the S3 diagonal stiffener.

[0140] At the in Fig. In the approximately sinusoidal wave profile described in Figure 6, obliquely oriented sections 6 of the wave web predominate, namely in almost all longitudinal sections, except for the area immediately around the vertices. With a profile deviating from the sinusoidal wave profile, the area fraction that does not run obliquely, i.e., that which runs at least approximately essentially parallel to the longitudinal direction (compare the section in Figure 6), can be... Fig. 6 indicated sections 7), may be much larger, e.g. in the case of trapezoidal profiles.

[0141] It should be understood that the static design of the transverse stiffening / transverse connection components described here, in particular stiffening elements, can also be carried out in accordance with any applicable regulations or standards that may be territorially restricted. For example, both transverse stiffening elements (crossbeam components) and diagonal stiffening elements (connectors) can be designed for the corresponding load combinations of the respective components involved; this applies in particular to the achievable load-bearing capacity and the plastic yield strength. The design concept presented here allows for the use of different materials depending on the requirements, which can also lead to material savings in applications with comparatively low load-bearing capacity requirements. In applications with particularly high or strict stiffness and load-bearing capacity criteria, the use of connectors or other components can be significantly reduced.Diagonal stiffeners can also incorporate a safety factor, e.g., in the single-digit percentage range of the nominal load-bearing capacity. Such deviations in load-bearing capacity can, if necessary, be compensated for, e.g., by adjusting the thickness of the transverse stiffeners, possibly only locally at the relevant, particularly stressed connection points or longitudinal positions. The resulting dimensions according to the static design of the stiffener elements can remain within the previously described structural limits. The static dimensioning and design can also be carried out using computer-aided design.

[0142] The design concept described here, or the associated construction, is fundamentally transferable to all types of corrugated web beams, e.g. also applicable to trapezoidal sheet metal beams.

[0143] Furthermore, it allows for the adjustment of additional or different welding parameters or welding procedures.

[0144] With reference to Fig. Section 7 below explains further design features or special characteristics relating to the beam and stiffener components themselves. For example, a crossbeam of type S1 has a substantially rectangular profile, in which primarily or exclusively the end face facing the web is chamfered, described here by reference to the offset or seam angle. In addition, drainage openings 26 may also be provided, particularly in this type of crossbeam. A crossbeam of type S2 may be designed similarly to type S1, with different absolute dimensions, and optionally without drainage openings. A connecting piece of type S3 preferably has an end face facing the web with a chamfer or seam angle (described here as the seam angle of the joint) that is greater than the offset or seam angle of crossbeams of types S1 and S2, in particular greater than 30°.The material thickness is preferably less, e.g. by a factor of 0.5.

[0145] With reference to the Fig. 8 and Fig. Section 9 below describes further design features or special characteristics of the material-fit integration of the beam and stiffener components in an arrangement within the corrugated web beam flange, wherein the dimensions of the corrugated web beam are, for example: height 333 mm, width 160 mm, sheet thickness 8 mm; where stiffeners type S1 and S2, for example, have a sheet thickness of 10 mm and stiffener type S3, for example, has a sheet thickness of 5 mm. Advantageous arrangement principles along the wavelength or with respect to certain relative longitudinal positions, as well as with respect to assembly, can be explained in accordance with the present invention. The arrangement height of the diagonal stiffener type S3 (angled connecting piece) relative to the stiffener elements S1 and S2 is also noteworthy. For galvanizing reasons, it is advantageous to dimension the component height of S3 approximately 50 mm lower than the component height of the transverse stiffeners.The welds between S3 and S1 or S2, as well as the welds to the web, are therefore preferably centered, in particular 25 mm above and below the inner flange surface, respectively. These clearances thus ensure the unimpeded flow of zinc or coating fluid with a good safety factor, thereby meeting the requirements of standard / intended corrosion protection methods.

[0146] In the Fig. Figure 8 shows sectional and side views of the construction in the area of ​​the inflection points on an exemplary corrugated web beam. In this longitudinal section, four stiffening elements are preferably used (three types): two transverse stiffeners (S1, S2), each in combination with a diagonal stiffener (S3). Fig. Figure 8A shows the weld seams a and the relative position of the joining partners S1 and S3. Fig. Figure 8B shows a longitudinal view of the corrugated web beam, illustrating the relative arrangement of the diagonal stiffener (S3) on the corresponding transverse stiffener S1, S2. Fig. Figure 8C shows the weld seams a and the relative position of the joining partners S2 and S3. The transverse stiffeners S1 and S2 are preferably also welded to the top and bottom flanges of the corrugated web beam, indicated by the weld seams a at the corresponding interface / contact region.

[0147] In the Fig. Figure 9 shows sectional and side views of the structure in the area of, or at least near, the wave crest and trough (peak and base points, respectively). In this longitudinal section, three stiffener elements (two types) may suffice, since the preferably direct connection of the wider transverse stiffener S1 to the web takes over or can replace the function of a diagonal stiffener in this area. Fig. 9A shows the weld seam a between a crossbeam S1 directly attached to the corrugated web. Fig. Figure 9B shows a longitudinal view of the corrugated web beam, illustrating the relative arrangement of the diagonal stiffener (S3) on the transverse stiffener S2. Fig. Figure 9C shows the weld seams a and the relative position of the joining partners S2 and S3. The transverse stiffeners S1 and S2 are preferably also welded to the top and bottom flanges of the corrugated web beam, indicated by the weld seams a at the corresponding interface / contact region.
