Abstract
Description
TECHNICAL AREA
[0001] The present invention relates to arrangements for the shear-resistant connection of components according to claims 1 and 7, a composite element comprising components which are connected by these arrangements according to claim 10, a ceiling element comprising such a composite element according to claim 13, a floor slab comprising a supporting structure and such a ceiling element according to claim 14, a solid component comprising a first connecting device according to claim 15, and a wooden component comprising a second connecting device according to claim 16. STATE OF THE ART
[0002] Timber-concrete composite slabs (HBV) are hybrid slabs that emerged in the first half of the 20th century due to a shortage of reinforcing steel. In reinforced concrete slabs, the reinforcing steel acts statically on the tension side, or, viewed from the installed state of the slab, predominantly at the bottom, and was replaced with wood due to this shortage. The concrete, according to its thickness, continues to act on the compression side, or, viewed from the installed state of the slab, predominantly at the top. This static behavior necessitates a connection between the two components at their joint, preventing free movement along this joint. This so-called shear bond can be achieved through positive locking, mechanical fasteners, or adhesive bonding.
[0003] A composite timber-concrete (CCT) slab essentially consists of concrete, timber, and shear connection. Given the differences between timber and solid construction, its production presents new challenges, as timber and concrete must be joined together. Several production methods are available. One option is to manufacture the entire CCT slab as a prefabricated element in the factory and erect it as such. A second option involves producing prefabricated timber and concrete elements, with the shear connection being created on-site. In a third option, the timber components are prepared in the factory, while the concrete is poured on-site. A fourth option involves carrying out all work on-site.
[0004] Depending on the local, architectural, structural, economic, or even ecological conditions of the construction project, a different method may be more suitable. For example, systems using precast concrete elements offer many advantages but are often considered uneconomical. Precast systems offer less flexibility in design but provide advantages in terms of construction time (parallel construction processes, no formwork removal times, short assembly time), construction moisture, quality (manufacturing conditions in the precast plant), material consumption, and reuse.
[0005] The shear connection is considered a central element of composite slabs. Important properties of the shear connection are load-bearing capacity, stiffness, and design. These properties significantly determine the possible manufacturing methods and influence the resulting cost-effectiveness of the structure.
[0006] With the increasing availability of reinforcing steel from the beginning of the second half of the 20th century, interest in composite concrete slabs (HBV slabs) receded. The current focus on decarbonization and CO2 storage in the construction sector has revived interest in HBV slabs. Future construction forecasts highlight the digitalization of processes, business models, and products, climate change, and the scarcity of land and raw materials. Based on these factors, the demand for precast systems should increase significantly; specifically, systems that meet the following criteria are in demand: No temporary support (shoring) required. Reduces concrete to a minimum. Offers quick and easy assembly and logistics. Provides immediate weather protection without additional effort. Connects wood and concrete mechanically without grouting, allowing for material-separated dismantling.
[0007] A wood-concrete composite element is known from CH 713 461 A1, which is designed exclusively for use with precast concrete elements. Instead of a mechanical fastener, the shear bond is achieved through a positive fit. For this purpose, recesses are provided in the precast concrete element and the wood, which are then filled with concrete on site. Due to the drying time, this requires temporary support.
[0008] WO 2012 / 135875 A1 discloses a timber-reinforced concrete composite element in which the shear connection is created via notches (positive locking) in the timber. In this design, the concrete and the timber cannot be separated without damage.
[0009] EP 1 528 171 A2 discloses an HBV system which is prefabricated and does not allow non-destructive separation of concrete and wood. PRESENTATION OF THE INVENTION
[0010] It is an object of the present invention to provide an arrangement for the shear-resistant connection of components which enables non-destructive dismantling.
[0011] This problem is solved by an arrangement according to claim 1 and an arrangement according to claim 7.
[0012] This means that, in a first aspect, an arrangement for the shear-resistant connection of a first component to a second component is specified, wherein this arrangement comprises a first connecting device and a second connecting device. The first connecting device can be pre-assembled in the first component, in particular, at least partially embedded in it. The second connecting device can be pre-assembled in the second component, in particular, partially bonded and / or positively interlocked and / or force-fitted to it, and preferably bonded, welded, or screwed. Bonding is preferred if the second component is a wooden component, while welding is preferred if the second component is a metal component such as a steel beam (see also below).The first connecting device comprises a housing that defines a cavity, a plate element arranged in the cavity, the plate element having a connecting opening, and a first connecting element. The second connecting device comprises or consists of a second connecting element. When the first and second components are connected, the second connecting element is partially receptible into the cavity and can be passed through the connecting opening in the plate element. The first connecting element and the second connecting element are detachably mechanically connected to one another.
[0013] The mechanically detachable first and second connecting elements allow the first and second components to be detachably mechanically connected. In particular, the first and second connecting elements permit the first and second components to be detachably mechanically connected. Detaching the connecting elements, and thus separating the components, occurs without destroying or damaging any of the parts.
[0014] For the sake of simplicity, the arrangement for the shear-resistant connection is also sometimes referred to as the shear connection arrangement.
[0015] The first and second connecting elements are preferably force-fit connections. Additionally or alternatively, the first connecting element comprises an internal thread and the second connecting element an external thread to form a threaded connection. Particularly preferably, the first connecting element is a nut and the second connecting element is a threaded rod.
[0016] Preferably, the housing has an open bottom, and the second connecting element can be received into the cavity of the housing through the open bottom. Additionally or alternatively, the housing has an open top, and the first connecting element can be received into the cavity through the open top and connected to the second connecting element.
[0017] Viewed along a circumferential direction, the housing is preferably formed essentially circumferentially, i.e., preferably has an essentially circumferential housing wall. However, the underside and the top side of the housing opposite the underside are preferably open. When the first and second components are connected, the open underside of the housing preferably faces the top side of the second component and, in particular, rests upon it. The second connecting element is preferably accessible through the open underside of the housing into the cavity of the housing and can be guided through the connecting opening of the plate element. The open top side of the housing preferably faces away from the second component, and especially away from its top side.The first connecting element is preferably accessible through the open top of the housing into the cavity of the housing and can be connected to the second connecting element, which is guided through the connecting opening of the plate element. In the received state, the second connecting element preferably projects partially into the cavity and through the connecting opening of the plate element. The second connecting element preferably has a free end, and the first connecting element can be connected to the second connecting element in the region of this free end. In particular, the first connecting element is a nut that is screwed onto the free end of the second connecting element, which is in the form of a threaded rod.
[0018] Preferably, the housing and / or the plate element and / or the first connecting element and / or the second connecting element comprise or consist of at least one metal, preferably steel.
[0019] Preferably, the plate element is arranged at a first angle in the cavity, and the second connecting element can be pre-assembled at a second angle in the second component. The first and second angles are preferably the same and / or are between 30° and 50°, preferably 45°.
[0020] Preferably, the housing has two opposing receiving openings into which two opposing edge regions of the plate element are received, in particular pressed in. The housing and the plate element can thus be pressed together. Welding or the like is therefore not required, but would be possible.
[0021] However, it is equally conceivable that the housing and the plate element are formed in one piece, for example in the form of a single casting.
[0022] Preferably, the first connecting device has at least one, preferably two, elongated stabilizing elements, in particular threaded rods. Preferably, the housing has at least one, and preferably two, opposing openings, in particular threaded openings, into which the at least one, and preferably the two, elongated stabilizing elements are partially received. However, other embodiments of the stabilizing element(s) are equally conceivable. For example, the elongated stabilizing elements can project outwards from opposite sides of the housing in a wing-like manner. These wing-like stabilizing elements can also be formed integrally with the housing, for example, again in the form of a housing comprising the stabilizing elements as a cast part.
[0023] Preferably, the stabilizing element(s) extend parallel to a joint formed between the first and second components when they are connected. This joint extends between a side of the first component facing the second component and a side of the second component facing the second component, and preferably occurs at the interface between the two components. The first and second components preferably each extend along a longitudinal direction, or in other words, are elongated components. The joint preferably runs parallel to the longitudinal direction of the first component and the longitudinal direction of the second component. These longitudinal directions can also be understood as the load-bearing directions of the respective components.As will be mentioned below, at least one of the components may be a beam, in which case the load-bearing direction corresponds to the beam direction.
[0024] As will be discussed in more detail below, the first component is preferably arranged on the top side of the second component. In this case, the joint is preferably formed between the underside of the first component facing the second component and the top side of the second component facing the first component.
[0025] Statements concerning an orientation or arrangement with respect to the joint between the first and second components therefore preferably apply analogously to the longitudinal direction of the first component or to the longitudinal direction of the second component.
[0026] In the assembled state of the first and second components, particularly when connected to a supporting structure (see below), the joint or the longitudinal directions of the first and second components preferably run parallel to a horizontal direction. This horizontal direction, in turn, runs perpendicular to a vertical direction, the vertical direction extending vertically upwards from a floor or substructure. The stabilizing elements preferably extend at an angle, particularly at right angles, outwards from the housing. In the assembled state of the first connecting element, the stabilizing element(s) are preferably at least partially, and particularly completely, arranged within the first component, and especially embedded in concrete therein.
[0027] In a second aspect, an arrangement for the shear-resistant connection of a first component to a second component is specified, wherein this arrangement comprises a first connecting device and a second connecting device. The first connecting device can be arranged at least partially in the first component. The second connecting device can be pre-assembled in the second component, in particular partially form-fitted and preferably bonded to it. The first connecting device comprises at least one first connecting element. The second connecting device has a receiving element which can be received in a recess of the second component. The receiving element has at least one connecting opening with a second connecting element. The first connecting element can be partially received into the connecting opening in the receiving element. The first connecting element and the second connecting element can be detachably mechanically connected.
[0028] In this second embodiment, the first and second components can also be detachably mechanically connected to one another by means of the mechanically detachable first and second connecting elements. In particular, the first and second connecting elements of this second embodiment also allow the first and second components to be detachably mechanically connected to one another, which enables non-destructive disassembly of the components.
[0029] In this second embodiment, the first connecting device is preferably designed to be arranged at least partially within the first component, in particular to be received in a recess in the first component. When the first and second components are connected, the first connecting device is at least partially arranged within the first component, in particular received in its recess. The recess may be a bore through the first component. The recess preferably runs at an angle, in particular perpendicular to a joint formed between the first and second components when they are connected. Therefore, when the two components are connected, it is further preferred that the first connecting device runs at an angle, in particular perpendicular to the joint.
[0030] In this second embodiment, it is further preferred that the first connecting device can be pre-assembled in the second component. That is, before the first and second components are assembled, it is preferred that the first connecting device is at least partially arranged on and / or in the second component. Particularly preferably, the first connecting element is detachably mechanically connected to the second connecting element. When the first and second components are connected, the second connecting device is preferably at least partially, and particularly preferably completely, arranged in the second component. The first connecting element and the second connecting element are preferably force-fit. Particularly preferably, the first connecting element has an external thread and / or is a threaded rod, and the second connecting element preferably has an internal thread and / or is a threaded opening.
[0031] In this second embodiment, the second connecting device preferably comprises at least one fastening element. The fastening element is preferably pre-assembled in the second component, in particular partially form-fittable, and especially adhesively bondable, and / or is a threaded rod. Preferably, the fastening element is partially receptacleable in a fastening opening, preferably a threaded opening, in the receiving element and is preferably detachably mechanically connected to it.
[0032] In this second embodiment, the first connecting device preferably comprises at least one shell element. The shell element is preferably pre-assembled in the first component, particularly in a recess in the first component, and particularly at least partially embedded in concrete therein. Preferably, the shell element and the first connecting element are designed such that, in a connected state of the first and second components, the first connecting element extends partially through and out of the shell element. Additionally, preferably at least one filling element, particularly a grout such as a grout mortar, can be arranged in the first component, particularly in a recess in the first component and, if present, in the shell element.
[0033] This means that in this second embodiment, the first connecting device can optionally comprise at least one sheathing element, which can be pre-assembled in the first component, particularly in the aforementioned recess in the first component. In this case, it is preferred that the first connecting element, when the first and second components are connected, extends partially through and beyond this sheathing element. The sheathing element is preferably a casing tube or the like, which is at least partially arranged in the recess and, for example, embedded in concrete therein. Additionally, a filling element can be arranged in the first component, particularly in the recess. That is, preferably the recess in the first component is cast. In order for the first and second components to be separated from each other in this case, this casting must also be removed. This could be done by means of core drilling.If a shell element is present, the filling element can be provided in the shell element.
[0034] In this second embodiment, the first connecting element is preferably arranged at an angle, particularly perpendicular to, the joint formed between the first and second components. Additionally or alternatively, the fastening element of the second connecting device is preferably arranged at an angle, particularly at an angle of 30° to 50°, preferably 45°, relative to the joint.
[0035] In a further aspect, a composite element comprising at least one first component and at least one second component is specified. The first component and second component are connected to each other in a shear-resistant manner and are essentially completely separable without damage by at least one arrangement according to the first aspect as described above and / or by at least one arrangement according to the second aspect as described above.
[0036] The first component is preferably arranged at least partially on a top side of the second component. Or, put another way, the second component is preferably arranged on a bottom side of the first component.
[0037] Preferably, the first and second components are connected to each other via several shear-resistant connection arrangements, or more simply, via several shear connection arrangements. These arrangements can be those according to the first aspect and / or those according to the second aspect. When reference is made below to an arrangement or arrangements, these statements apply to the arrangement(s) according to the first aspect as well as to the arrangement(s) according to the second aspect.
[0038] Two or more of the arrangements are preferably arranged one behind the other, i.e., "in a row," along the joint or along the longitudinal direction of the first and second components. The distance between two successive arrangements can be the same or different. Additionally or alternatively, two or more of the arrangements can be arranged one behind the other along a transverse direction running perpendicular to the joint or the longitudinal direction of the components. In other words, these arrangements can also be arranged "side by side."
[0039] Preferably, two or more second components are arranged on the underside of the first component. Preferably, two or more of these second components are arranged parallel to each other on the underside of the first component.
[0040] Essentially completely non-destructively separable components connected together preferably means that no parts are destroyed with the exception of the filling element, for example the potting compound, in the first component of the arrangement according to the second aspect, if present.
[0041] As will be discussed in more detail later, the first component is preferably a solid component, in particular a concrete component such as a precast concrete element, and the second component is a timber component such as a ceiling rib, a timber panel, or a beam. The composite element is therefore preferably a timber-concrete composite element. It should be understood that not only concrete but also other solid building materials are conceivable. Statements concerning concrete thus preferably apply analogously to other solid building materials and vice versa. The same applies to the second component, which does not have to be a timber component but could, for example, also be a metal component such as a steel component, e.g., a steel beam.
[0042] The wood-concrete composite element preferably has two or more wood components per concrete component.
[0043] Preferably, the composite element comprises at least one support device. The support device preferably comprises a support element arranged on a top surface of the first component, wherein the first component projects beyond an end face of the second component in such a way that the second component indirectly supports the supporting structure via the first component, and wherein the support element introduces a support force into the first component.
[0044] In this context, the term "load-bearing structure" refers to all structural components necessary for transferring the forces acting on a structure such as a building to ensure its stability. The load can be static (at rest) or dynamic. These can occur in combination.
[0045] The terms "primary" and "secondary" establish a hierarchy within the load-bearing structure. These terms are sometimes used inconsistently. Here, the primary structure is understood as the main load-bearing system. This means that the primary structure preferably consists of a main support structure such as a beam, girder, wall, or truss, which also includes columns that transfer the loads to the foundation. The secondary structure preferably consists of a secondary load-bearing system such as floor elements, joists, etc., which transfer the loads to the primary structure.
[0046] The support element is preferably plate-shaped and / or comprises or consists of at least one metal, preferably steel.
[0047] The first component preferably has at least one recess. The recess is preferably arranged at an angle, in particular perpendicular to the joint. The recess may be a bore through the first component. It is conceivable that the support device further comprises at least one casing element, such as a casing tube, which is at least partially arranged in the recess and, for example, embedded in concrete. Furthermore, the support element preferably has at least one through-opening. The through-opening preferably extends at an angle, in particular perpendicular to the joint. The recess of the first component and the through-opening of the support element are preferably arranged one above the other. The support device preferably further comprises at least one support connecting element and at least one support fastening element.The support connecting element is preferably pre-assembled in the second component, particularly partially positively connected to it, and especially preferably bonded to it. The support connecting element is particularly preferably a threaded rod. The support connecting element is preferably arranged at an angle, particularly perpendicular to the joint. The support fastening element preferably extends through the through-opening of the support element and the recess of the first component, and, if present, through the sleeve element in the first component and partially into the second component, where it is connected to or in contact with the support connecting element, for example via a sleeve element or the like. The support fastening element can be a screw such as a countersunk screw.In particular, a support fastening element in the form of a screw and a support connecting element in the form of a threaded rod can each be connected to a sleeve element in the form of an internally threaded sleeve and thus be connected to each other via the internally threaded sleeve. This means that the support device is preferably directly mechanically connected to the second component. The support device is preferably indirectly connected to the first component.
[0048] Preferably, the support device comprises at least two support connecting elements, which are connected to at least two support fastening elements in the second component by means of at least two through-openings in the support elements and at least two recesses (and optionally by at least two sleeve elements) in the first component. These at least two elements, openings, or recesses are preferably arranged next to each other.
[0049] Viewed along the joint, the end face of the first component preferably projects beyond an end face of the second component. Or, put another way, the length of the first component, viewed along the joint, is greater than the length of the second component.
[0050] The composite element can comprise one or more support devices. In particular, the first component can comprise one or more support elements, each of which is arranged in an end region of the second component, i.e., in the region of its end face. That is to say, preferably a support is provided in each end region of the second component. Furthermore, it is preferred that one or more support devices are provided in the region of a so-called element joint, i.e., that they comprise support elements which each project laterally beyond a first component and can be arranged on the surface of another first component that is arranged next to said first component. That is to say, two types of support can be provided.A first type of support is provided by the support devices just described, which are located in the area of the element joint, with each support plate positioned over two adjacent first components. A second type of support can be provided within a first component, with the support device arranged such that the support plate is located solely on the first component and does not extend over an end face of the second component. In this case, the support device is located in a so-called transverse joint.
[0051] Preferably, the composite element comprises at least one first disc connection device. The first disc connection device is preferably arranged at least partially in the first component and, in particular, embedded in it, and can be connected to a second disc connection device on a supporting structure in such a way that displacement of the composite element relative to the supporting structure is prevented.
[0052] The shear connection device thus ensures a shear-resistant connection of the shear forces of the composite element to the primary structure, so that, for example, a floor diaphragm can be formed for building stability. That is, a floor diaphragm is preferably provided for stabilizing a building. The first components, for example, in the form of concrete elements, are therefore preferably designed as shear elements. In this case, it is preferred that these individual elements are connected to form a floor diaphragm. This is preferably achieved by connecting the individual elements to each other (e.g., edge parallel to beam) via the shear connection device, since there is, for example, a beam under each joint. Additionally or alternatively, this can be achieved by a primary structure (e.g., edge perpendicular to beam and partly parallel) and via a shear connection device.The shear connectors can connect the components and the primary structure under shear. These forces can also be referred to as shear forces to avoid confusion. This is a different type of shear than that for which the shear connection arrangements are designed. The shear connectors can also be attached to a wall or a steel beam via an angle bracket, with the bracket preferably resting on top. That is, preferably the shear connector is arranged in the first component and the load-bearing element of a structure. However, it is equally conceivable that the shear connector is connected, for example, to a wall such as a concrete wall or to a steel beam.
[0053] The first disc connection device preferably comprises at least one disc connector housing, which is at least partially and preferably completely arranged in the first component, and in particular is embedded in concrete therein. The disc connector housing preferably defines a cavity. Furthermore, the disc connector housing preferably has a housing wall which, viewed along a circumferential direction of the disc connector housing, is substantially circumferential. The first disc connection device preferably further comprises at least one elongated stabilizing element, and the disc connector housing preferably has at least one opening for partially receiving the elongated stabilizing element. The elongated stabilizing element is preferably at least partially received in the first component and in particular is embedded in concrete therein.
[0054] The elongated stabilizing element is preferably a threaded rod, and the opening in the disc connector housing is preferably a threaded opening. The disc connector housing and / or the elongated stabilizing element preferably comprises or consists of at least one metal, in particular steel. The elongated stabilizing element preferably runs parallel to the joint between the first and second components. A top and / or an opposite bottom of the disc connector housing is preferably open.
[0055] In a connected state of the composite element with a supporting structure, the underside of the disc connector housing is preferably facing a top side of the supporting structure.
[0056] The first disc connection device is therefore preferably arranged in the area of the front face of the first component and is designed to be connected to a second disc connection device on the supporting structure, in particular to a second disc connection device arranged on a supporting element of the supporting structure.
[0057] This means, and as will be explained in more detail below, a disc connection arrangement comprising at least one first disc connection device and one second disc connection device is preferably provided. The first disc connection device is preferably arranged on the first component, and the second disc connection device is preferably arranged on the supporting structure, in particular on a supporting element of the supporting structure.
[0058] The second shear connection device preferably comprises a shear connector connecting element, which is at least partially arranged in the load-bearing element of the structure and is, in particular, positively connected to it and preferably bonded. The shear connector connecting element is preferably a so-called shear connector. The shear connector is preferably a threaded rod if the load-bearing element is made of wood. In this case, the shear connector or threaded rod can, for example, be screwed or glued into the wood. If the load-bearing element is a steel element, the shear connector is preferably a headed stud anchor. If the load-bearing element is a concrete element, the shear connector is preferably a reinforcing bar or a concrete anchor.
[0059] The disc connector connecting element is preferably arranged at an angle, in particular at right angles to a longitudinal direction of the supporting structure running parallel to the connection joint.
[0060] The shear connector connecting element preferably projects beyond the top surface of the support element and, in a composite element connected to the support structure, at least partially into the shear connector housing in the first component. Particularly preferably, the shear connector connecting element extends completely through the shear connector housing in the first component and even beyond the top surface of the shear connector housing. A free end of the shear connector connecting element is thus preferably arranged outside the shear connector housing.
[0061] Furthermore, it is preferred that the disc connection assembly has at least one disc connector fastening element, for example a nut, which can be fastened to the free end of the disc connector connecting element. Preferably, a washer or the like is also provided, which is arranged between the disc connector fastening element and the top of the disc connector housing on the disc connector connecting element and, in particular, rests on the top of the disc connector housing.
[0062] Furthermore, it is preferred that the second disc connector has at least one insert element which can be attached to the supporting structure, in particular to the supporting element. This is especially relevant if the supporting element is made of wood. Specifically, the insert element is recessed into the top surface of the supporting element, preferably in a recess in the top surface of the supporting element. The top surface of the recessed insert element is preferably flush with the top surface of the supporting element in areas outside the recess. The insert element preferably has at least one through-opening through which the disc connector extends.
[0063] The disc connector assembly can further comprise at least one sheathing element, for example a sleeve or a precision tube, which is arranged inside the disc connector housing and around the disc connector connecting element. Additionally or alternatively, at least one filling element, in particular a grout such as a grout mortar, can be arranged in the disc connector housing.
[0064] Particularly preferably, the second disc connection device has at least one further disc connector connecting element, and the insert element has at least one further through-opening through which the further disc connector connecting element extends. This further disc connector connecting element is preferably connected to a further first disc connection device of a further first component.
[0065] This means that preferably a second disc connection device comprising at least two disc connector connecting elements and an insert element comprising at least two through-openings is attached to a supporting element of a supporting structure. Each of the disc connector connecting elements is connected to a first disc connection device of a first component.
[0066] Other components such as the filling element and / or the sleeve element and / or the disc connector fastening element and / or the base plate can also be arranged analogously in the further first disc connection device.
[0067] The composite element can comprise one or more first disc connection devices. In particular, the first component can comprise one or more first disc connection devices arranged in the region of the end faces of the first component.
[0068] In another aspect, a ceiling element is specified as comprising or consisting of at least one composite element as described above.
[0069] All statements concerning the composite element preferably apply analogously to the ceiling element and vice versa.
[0070] In another aspect, a floor slab is defined as comprising a supporting structure and at least one slab element as described above, wherein the slab element is connected to the supporting structure.
[0071] All statements concerning the floor slab encompassing the ceiling element preferably apply analogously to the ceiling element itself and vice versa.
[0072] In another aspect, a solid component, in particular a concrete component such as a precast concrete element, comprising a first component and at least one first connecting device as described above, is specified.
[0073] The first connecting device can be either the first connecting device of the shear connection arrangement according to the first aspect or the first connecting device of the shear connection arrangement according to the second aspect. The solid component, in particular the concrete component, is preferably plate-shaped.
[0074] All statements concerning the first component preferably apply analogously to the solid component and vice versa.
[0075] This means that the solid component can, for example, further comprise at least one support element of the support device. Additionally or alternatively, the solid component can further comprise at least the first disc connection device. Etc.
[0076] In another aspect, a timber component is defined as comprising a second component and at least one second connection device as described above. The second connection device can be either the second connection device of the shear connection arrangement according to the first aspect or the second connection device of the shear connection arrangement according to the second aspect. The timber component is, in particular, a ceiling rib or a beam. As mentioned previously, however, the second component can also be a different component, e.g., a metal component, in particular a steel component such as a steel beam.
[0077] All statements concerning the second component preferably apply analogously to the wooden component and vice versa.
[0078] This means that the wooden component can, for example, further include at least one support connecting element of the support device, etc. BRIEF DESCRIPTION OF THE DRAWINGS

DESCRIPTION OF PREFERRED EXECUTION FORMS
[0080] Figure 1aFigure 3 shows a floor slab 3000 comprising a supporting structure 3001 and several slab elements 2000, which are connected to the supporting structure 3001. Each of the slab elements 2000 is a composite element 1000 consisting of a first component 2 and a second component 3. In the illustrations shown here, the first component 2 is a solid component, specifically a concrete component in the form of a slab-shaped precast concrete element. The second component 3 is a timber component, specifically a slab rib or a timber beam. As can be seen in particular with regard to the Figures 6a to 6e and the Figures 7a to 7e As explained in detail, the concrete component and the wooden component are each connected to each other in a shear-resistant manner via arrangements 1, 100, also called shear connection arrangements. The shear connection arrangements 1, 100 allow for non-destructive dismantling. Figures 6a to 6eThey show a push-fit connection device 1 according to a first aspect and the Figures 7a to 7e They show a push-fit connection device according to a second aspect. As, for example, in the Figures 1a and 1bAs can be seen, the first component 2 is arranged on a top surface 17 of the second component 3, and the second component 3 is arranged on a bottom surface 27 of the first component 2. Several arrangements 1 (although not shown in the figures, this applies analogously to the arrangements 100 according to the second aspect) are arranged one behind the other, i.e., "in a row," along a joint F or along a longitudinal direction L1 of the first component 2 and along a longitudinal direction L2 of the second component 3. Furthermore, several arrangements 1 are arranged one behind the other along a transverse direction Q running perpendicular to the joint or the longitudinal direction of the components. In particular, several second components 3, 3a, ... are arranged on the bottom surface 27 of the first component 2, see e.g. Figure 1b and 2aThe second components 3, 3a, ... are arranged parallel to each other on the underside 27 of the first component 2. The connecting joint F is formed between the underside 27 of the first component 2 facing the second component and the top side 17 of the second component 3 facing the first component 2. In an assembly state of the first and second components 2; 3 or of the composite element 1000, as shown in Figure 1a In the connection shown with the supporting structure 3001, the connection joint F or the longitudinal directions L1; L2 of the first and second components 2; 3 run parallel to a horizontal direction H. The horizontal direction H in turn runs perpendicular to a vertical direction V, the vertical direction V extending vertically upwards from a floor or subsoil.
[0081] As from the Figures 1a to 5 As can be seen, the composite elements 1000, in addition to the shear connection arrangements 1, 100, also have further components.
[0082] For example, support devices 1001 are provided, which enable indirect support. The assembly of a composite element 1000 is simplest when it can "only" be positioned and secured. If parts have to be inserted into connectors, this can lead to difficulties due to tolerance requirements. With indirect support, as here via the first component 2, i.e., via the precast concrete element, simple assembly is ensured. The entire support force from the second component 3, here the ceiling rib, is transferred via the projecting end face of the precast concrete element 2 into the higher-level supporting structure 3001. The resulting offset of forces causes additional forces in the precast concrete element 2, which can be absorbed by reinforcement measures in the form of the support device 1001. Because the ceiling rib 3 is not directly connected to the higher-level supporting element 3003 in the load-bearing hierarchy (e.g.,Since the primary structure (beam) is connected, there is one less dependency and more possibilities arise. For example, the ceiling rib 3 can be designed with a gap to the beam. This creates a space which can be used, for example, for routing installations. As explained below in connection with the... Figures 8a to 8e As will be explained in more detail later, the assembly is screw-based and a purely mechanical connection. This connection is therefore reversible. Furthermore, assembly at right angles to the joint F is possible.
[0083] Another component of the composite elements 1000 are disc connection devices 1008; 1009 or disc connection arrangements 1017, which are used in connection with the Figures 9a to 9eThis will be explained in detail. The diaphragm connection devices 1008; 1009 and diaphragm connection assemblies 1017 prevent the free mutual displacement parallel to the connection joint F of two components, for example, between a first component 2 and another first component 2a, or between the first component 2 in the form of the precast concrete element and the second component 3 in the form of the timber component. Furthermore, the diaphragm connection devices 1008; 1009 and the diaphragm connection assemblies 1017 connect the composite element 1000, here the ceiling element 2000, to the hierarchically superior load-bearing element 3003 (e.g., beam). The diaphragm connection devices 1008; 1009 and the diaphragm connection assemblies 1017 thus contribute to the overall stability of the building. The diaphragm connection devices 1008; 1009 or disc connection arrangements 1017 a screwable assembly, so that the connection can be detached without damage.Furthermore, assembly at right angles to the connecting joint F is possible.
[0084] With regard to the Figures 6a to 6eThe shear connection arrangement 1, as described in the first aspect, will now be explained in detail. As can be seen from these figures, arrangement 1 has a first connection device 4, which is pre-assembled in the first component 2, in particular embedded in concrete. Arrangement 1 also has a second connection device 5, which is pre-assembled in the second component 3, in particular partially bonded to it. The first connection device 4 comprises a housing 6, which defines a cavity 7. A plate element 8 with a connection opening 9 is arranged in the cavity 7. The housing 6 has two opposing receiving openings 19; 20, into which two opposing edge regions 21; 22 of the plate element 8 are received and pressed in. Viewed along a circumferential direction U of the housing 6, the housing 6 is thus formed circumferentially, with the exception of the receiving openings 19; 20 and openings 25; 26 (see below).Furthermore, the first connecting device 4 has a first connecting element 10 in the form of a screw nut with an internal thread 12. The second connecting device 5 consists of a second connecting element 11 in the form of a threaded rod with an external thread 13 for forming a threaded connection with the internal thread 12 of the screw nut 10, thus forming a detachable mechanical connection.
[0085] The housing 6 has an open bottom 14, allowing the second connecting element 11 to be inserted into the cavity 7 of the housing 6 through the open bottom 14 and passed through the connecting opening 9 of the plate element 8. Furthermore, the housing 6 has an open top 15, allowing the first connecting element 10 to be inserted into the cavity 7 through the open top 15 and connected to the second connecting element 11. The second connecting element 11 has a free end 18, and the first connecting element 10 is connected to the second connecting element 11 at the free end 18. A washer 34 is placed between the first connecting element 10 and the plate element 8.
[0086] The first connecting device 4 further comprises two elongated stabilizing elements 23; 24 in the form of threaded rods. The housing 6 further comprises two opposing openings 25; 26 in the form of threaded openings, into which the two elongated stabilizing elements 23; 24 are partially received. As in Figure 6c As indicated, the plate element 8 is arranged at a first angle α in the cavity 7, and the second connecting element 11 is pre-assembled at a second angle β in the second component 3. In the example shown, the first angle α and the second angle β are the same and each measure 45°. When the first connecting element 10 is assembled, the stabilizing elements 23 and 24 are arranged completely within the first component 2 and extend outwards at right angles from the housing, see figure. Figure 6c .
[0087] With regard to the Figures 7a to 7eThe shear connection arrangement 100 will now be explained in more detail according to the second aspect. This arrangement 100 comprises a first connection device 101, which is partially arranged in the first component 2, and a second connection device 102, which is pre-assembled in the second component 3, in particular bonded therein. The first connection device 101 is received in a recess 29 in the first component 2. The recess 29, and ultimately also the first connection device 101, runs at an angle, here perpendicular to the connection joint F.
[0088] The first connecting device 101 comprises two first connecting elements 103, 103a, each in the form of a threaded rod with an external thread. The second connecting device 102 comprises a receiving element 104, which is received in a recess 28 of the second component 3. The receiving element 104 has two connecting openings 105, 105a, each with a second connecting element 106, 106a. The second connecting element 106, 106a has an internal thread and is a threaded opening. Each first connecting element 103, 103a is partially received in a connecting opening 105, 105a in the receiving element 104 and detachably mechanically connected to the second connecting element 106, 106a by means of the threaded connection.
[0089] The second connecting device 102 comprises two fastening elements 107, 107a, which are pre-assembled in the second component 3, in particular bonded therein. The fastening elements 107, 107a are threaded rods, each of which is partially inserted into a fastening opening 108, 108a in the form of threaded openings in the receiving element 104 and detachably mechanically connected to it. In the example shown here, the first connecting device 101 comprises two sleeve elements 109, 109a, each of which is pre-assembled in one of the recesses 29, 29a of the first component 1, in particular embedded in concrete therein. Furthermore, a filling element 110, 110a in the form of a grout is arranged in each of the recesses 29, in particular in each of the sleeve elements 109, 109a.With regard to the connecting joint F formed between the first and second component, the first connecting elements 103, 103a are each arranged at an angle y, here perpendicular, to it, see . Figure 7c The fastening elements 107, 107a of the second connecting device 102 are arranged at an angle δ of 45° with respect to the connecting joint F. As can be seen from the Figures 7a to 7d As can be seen, the first connecting device 101 further comprises upper and lower screw nuts 111, 111a and 112, 112a, respectively. An upper and lower screw nut 111, 112 and 111a, 112a, respectively, each serve to further secure the first connecting elements 103, 103a.
[0090] With regard to the Figures 8a to 8eAspects of the support device 1001 will now be explained in detail. The support device 1001 has a support element 1002, which is arranged on a top surface 30 of the first component 2 and transmits a support force into the first component 2. The first component 2 has two recesses 32, 32a in the form of bores that extend through the first component 2. Furthermore, the support device 1002 comprises two sleeve elements 1003, 1003a in the form of sheathing tubes, which are embedded in the recesses 32, 32a. In addition, the support element 1002 has two through-openings 1004, 1004a. The through-openings 1004, 1004a each extend at an angle, here perpendicular to the connecting joint F. A recess 32, 32a of the first component 2 and a through-opening 1004, 1004a of the support element 1002 are arranged one above the other.The support device 1001 further comprises two support connecting elements 1005, 1005a and two support fastening elements 1006, 1006a. The support connecting elements 1005, 1005a are threaded rods, which are pre-assembled in the second component 3, in particular bonded therein, and are arranged perpendicular to the joint F. The support connecting elements 1005, 1005a are connected to the support fastening elements 1006, 1006a via a sleeve element 1007, 1007a, respectively. The support fastening elements 1006, 1006a are screws, and the sleeve elements 1007, 1007a are internally threaded sleeves.
[0091] As from the Figure 1b and 8bAs can be seen, the end face 31 of the first component 2 projects along the joint F beyond an end face 33 of the second component 3. The support elements 1002 of the support devices 1001 are each arranged in an end region of the second component 2, i.e., in the region of its end face 31. In addition, support devices 1001 are also provided in the region of a so-called element joint E and arranged such that their support elements 1002 each project laterally beyond the first component 2 and are positioned on the surface 30 of another first component 2, which is arranged next to the aforementioned first component. Figure 1b and 8c .
[0092] With regard to the Figures 9a to 9eAspects of a disc connection arrangement 1017, comprising the first and second disc connection devices 1008 and 1009, will now be explained. The first disc connection device 1008 is partially embedded in the first component 2 and can be connected to a second disc connection device 1009 on the supporting structure 3001 in such a way that displacement of the composite element 1000 relative to the supporting structure 3001 is prevented. The first disc connection device 1008 comprises a disc connector housing 1010, which is completely embedded in the first component 2. The disc connector housing 1010 defines a cavity 1011. Furthermore, the disc connector housing 1010 has a housing wall 1012, which, viewed along a circumferential direction US of the disc connector housing 1010, is essentially circumferential.The first disc connector 1008 further comprises an elongated stabilizing element 1013 in the form of a threaded rod, and the disc connector housing 1010 has an opening 1014 in the form of a threaded opening for the partial reception of the elongated stabilizing element 1013. The elongated stabilizing element 1013 is at least partially embedded in the first component 2 and runs parallel to the connection joint F between the first and second components 2; 3. A top surface 1015 and an opposite bottom surface 1016 of the disc connector housing 1010 are open. In the connected state of the composite element 1000 with the supporting structure 3001, the bottom surface 1016 of the disc connector housing 1010 faces a top surface 3002 of the supporting structure 3000, see . Figure 1a and 9cThe first disc connection device 1008 is thus arranged in the area of the end face 31 of the first component 2 and is designed to be connected to the second disc connection device 1009 on the supporting structure 3001. The second disc connection device 1009 comprises a disc connector connecting element 1018 in the form of a threaded rod, which is partially arranged in and bonded to the supporting element 3003 of the supporting structure 3000. The disc connector connecting element 1018 is arranged at an angle, here perpendicular to a longitudinal direction LT of the supporting structure 3001 running parallel to the connection joint, see Figure 1. Figure 1aThe disc connector connecting element 1018 projects beyond the top surface 3004 of the support element 3003 and partially into and through the disc connector housing 1010 in the first component 2. A free end 1019 of the disc connector connecting element 1018 is thus located outside the disc connector housing 1010. Furthermore, the disc connection assembly 1017 has at least one disc connector fastening element 1020 in the form of a nut, which is attached to the free end 1019 of the disc connector connecting element 1018. A washer 1021 is also provided, which is arranged on the disc connector connecting element 1018 between the disc connector fastening element 1020 and the top surface 1015 of the disc connector housing 1010. The second disc connection device 1009 has an insert element 1022, which is attached to the supporting structure 3001, in particular in a recess 3005 of a top surface 3004 of the supporting element 3003.A top surface 1023 of the recessed insert element 1022 is flush with the top surface 3004 of the support element 3003 in areas outside the recess 3005. The insert element 1022 has a through-opening 1024 through which the disc connector connecting element 1018 extends. The disc connection assembly 1017 further comprises a sleeve element 1025, which is arranged inside the disc connector housing 1010 and around the disc connector connecting element 1018. Additionally, a filling element 1026 in the form of a potting compound is arranged in the disc connector housing 1010. The second disc connecting device 1009 has a further disc connector connecting element 1018a and the insert element 1022 has a further through-opening 1024a through which the further disc connector connecting element 1018a extends.This further disc connector connecting element 1018a is connected to a further first disc connecting device 1008a of a further first component 2a. In this way, one of the disc connector connecting elements 1018 or 1018a is connected to a first disc connecting device 1008 or 1008a of a first component 2 or 2a, respectively.
[0093] With regard to the Figures 10a to 10e Further possible applications of the composite elements 1000 and in particular also of the disc connection devices 1008; 1009 or of the disc connection arrangements 1017 are to be illustrated. Figure 10a shows composite elements 1000, 1000a,... comprising the concrete component 2, 2a,... and wooden components 3, 3a,... (not shown), wherein the composite elements are attached to a supporting element 3003 in the form of a wooden beam via shear connection devices 1008; 1009 or shear connection arrangements 1017 as explained above. Figure 10bFigure 1 shows such composite elements 1000, 1000a,..., wherein the composite elements 1000, 1000a,... are attached to a support element 3003 in the form of a steel beam via disc connection devices 1008; 1009 or disc connection arrangements 1017 as explained above. Figure 10c Figure 1 shows such composite elements 1000, 1000a, ..., wherein the composite elements 1000, 1000a,... are attached to a supporting element 3003 in the form of a concrete wall via disc connection devices 1008; 1009 or disc connection arrangements 1017 as explained above. Figures 10d to 10fFigure 1 shows such composite elements 1000, 1000a, ..., wherein the composite elements 1000, 1000a, ... are attached to a supporting element 3003 in the form of a concrete wall via disc connection devices 1008; 1009 or disc connection arrangements 1017 comprising an angle 1027. That is to say, the disc connection devices 1008; 1009 or disc connection arrangements 1017 shown here differ from the disc connection device described above, in particular in that no planar or flat insert element 1022 is provided, but rather that the insert element 1027 is bent and forms an angle. This allows the insert element or the angle 1027 to be connected both to the previously described recess 3005 of a top surface 3004 of the supporting element 3003 and to the concrete wall.
