Description

[0001] The present invention relates to reusable frame devices for constructing load-bearing structures, in particular vehicle structures. The invention further relates to a method for recycling a frame device for constructing load-bearing structures, in particular vehicle structures. The invention also relates to the use of several frame devices for manufacturing a load-bearing structure, e.g., a construction and / or residential container.

[0002] In the prior art, frame structures for car body constructions are known, typically consisting of aluminum or steel profiles. Extruded aluminum profiles are frequently used, fulfilling a load-bearing and / or cladding function. These manufactured semi-finished products must be adapted to the maximum loads that occur, often resulting in over-dimensioned structures, particularly in low-load areas. These designs often have limited possibilities for combining different materials, which restricts the potential for optimizing lightweight construction.

[0003] EP 3 597 514 A1 discloses a frame device, in particular for a top-mounted wall, consisting of at least four profile sections joined to form a rectangular unit. The profile sections have a tubular area with inwardly projecting longitudinal ribs. For connection at the corners, a screw engages through a first profile section into a housing with a circular cross-section provided inside a second, adjacent profile section.

[0004] In light of the prior art, the objective of the present disclosure is to provide a reusable frame device, a method for manufacturing the frame device, and a use of several frame devices, each of which is suitable to overcome at least some of the aforementioned disadvantages of the prior art.

[0005] For example, a frame device is to be created that allows flexible adaptation to load paths, avoids oversized structures, and ensures efficient connection of the frame device for reuse. Furthermore, the frame device of the present disclosure is to enable the integration of sustainable materials and a modular construction.

[0006] The problem is solved by the features of the independent patent claims. The dependent claims each contain optional further developments of the disclosure.

[0007] This task can be solved by a reusable frame device for constructing load-bearing structures. The frame device can be used in particular for constructing vehicle structures. The frame device can comprise at least two frame profile elements.

[0008] A load-bearing structure is, for example, a self-supporting side wall, floor and / or roof structure of vehicles and / or buildings and / or other constructions.

[0009] These frame profile elements can, for example, enclose an interior area of ​​the frame device. At least one of the frame profile elements can form several connecting sections. The connecting sections can be arranged successively in a radial direction relative to the interior area.

[0010] The connection sections can include at least one primary connection section and one secondary connection section.

[0011] Advantageously, the reusable frame device allows for a modular design, which enables flexible adaptation to different structural requirements.

[0012] The arrangement of the primary and secondary connection sections can help make the frame suitable for both primary use and reuse. This promotes resource-efficient construction, as the frame and its profile elements can be reused multiple times. This can contribute to reducing material costs and improving sustainability in vehicle construction and for the bodies of construction and / or residential containers.

[0013] For the purposes of this disclosure, a reusable frame assembly is a structure designed to be reused after its primary use, for example, as part of a car body structure for use in trains. This can contribute to resource conservation, as the frame assembly can be used for various applications, first for a primary purpose and then for a secondary purpose.

[0014] Load-bearing structures within the meaning of this disclosure can be structures that serve to absorb and transfer loads. The use of the frame device in load-bearing structures ensures a stable construction and increases the structural integrity of the overall structure.

[0015] Frame profile elements as defined in this disclosure can be key components of the frame device. These can be used to form the overall structure. For example, they can enable a stable, modular, and easily reusable frame device design in vehicle construction.

[0016] The interior of the frame device as defined in the present disclosure may, for example, be at least partially enclosed by the frame profile elements.

[0017] For example, the frame profile elements can form a closed frame around the interior.

[0018] Standardized and simple geometries, such as triangles or quadrilaterals, can be created around the interior. Triangles and quadrilaterals, as well as other polygons, can have any shape, for example, regular, symmetrical, irregular, etc.

[0019] These geometries allow for the construction of more complex load-bearing structures or modules, for example, to map load paths optimized for a specific load flow. This increases the efficiency of the frame structure and contributes to reusability, as less material is required and the load-bearing structures can be adapted to the respective local loads.

[0020] Furthermore, the interior can be filled. For example, one or more internal panels or elements made of sandwich material, such as with a foam core, wood core, or structured core, can be provided.

[0021] The structured core can, for example, consist of a corrugated, honeycomb, or ribbed material. This structuring contributes to the stiffness, stability, and weight reduction of the material, resulting in a better strength-to-weight ratio.

[0022] In the frame design, this allows for improved adaptation to loads and more efficient use of the materials employed. The interior can contribute to reducing the overall weight of the structure.

[0023] Thus, the interior can increase the efficiency of the frame device.

[0024] Connecting sections within the meaning of the present disclosure are areas of the frame profile elements that can serve for connection with other frame profile elements.

[0025] They are designed, for example, to enable the construction of a carriage body for trains in a primary use by means of primary connecting sections.

[0026] The secondary connection section can be used for a secondary purpose, for example in a recycled frame device for the production of a load-bearing structure, e.g. a construction and / or residential container.

[0027] A primary connection section is the section initially used to join the frame fixture in its primary application. It can be detached to expose the secondary connection section. This allows the frame fixture to be reused, thus conserving resources.

[0028] In accordance with the present disclosure, the secondary connecting section is exposed after the primary connecting section has been separated and serves for reconnection.

[0029] The radial direction within the meaning of the present disclosure can refer to the arrangement of the connecting sections in relation to the interior of the frame device.

[0030] In the context of this disclosure, the term "in a radial direction" can mean an orientation along a radius. A radius can be drawn outwards from the center of a circle or an estimated center point of any arbitrarily shaped structure or surface to the circumcircle. Thus, the term "in a radial direction" can mean an orientation from the center outwards.

[0031] The implementation of the connecting sections can have the technical effect that the frame profile elements can be connected to each other in a form-fit and / or force-fit manner, which can ensure a high stability of the structure.

[0032] By using connecting elements, such as snap-fit ​​or click systems that can create a mechanical snap connection, assembly time can be reduced and the reusability of the frame profile elements can be promoted.

[0033] The primary connection section may be arranged radially on the outside. The secondary connection section may be arranged radially on the inside.

[0034] Radially inward within the meaning of this disclosure may mean that the secondary connecting section may be arranged closer to the center of the interior of the frame device.

[0035] The secondary connection section can be concealed inside the frame profile element.

[0036] For example, it may be advantageous if the secondary connection section is protected and / or concealed during a primary use.

[0037] Furthermore, it may be provided that the secondary connection section and the primary connection section are formed directly adjacent to each other.

[0038] By exposing the secondary connection section after separating the primary connection section, a new outer surface of the frame profile element is preferably obtained, particularly for reuse of the same.

[0039] It can be provided that the primary connection section forms an original outer surface of the frame profile element in a radial direction. The primary connection section can, for example, serve as the original outer surface.

[0040] This outer surface ensures the primary purpose can be fulfilled while protecting the secondary connection section.

[0041] Furthermore, the secondary connection section can contribute to structural integrity during the first use, for example, to be available in an unused state for later reuse.

[0042] An internal profile can be understood as a profile that is arranged or formed within the secondary connection section and serves to connect with other frame profile elements.

[0043] A profile can refer to the entirety or only the internal structure of the frame profile element, for example an extruded profile, including the cavities or specific geometric features designed for structural reinforcement or for the attachment of connecting elements.

[0044] A connecting element within the meaning of the present disclosure may refer to a component that is specifically designed for the mechanical coupling of frame profile elements.

[0045] It can, for example, be formed from the inner profile or at least be a part of it.

[0046] A connecting element can preferably ensure a detachable and / or stable connection, for example through mechanical connections that can interlock.

[0047] For quick and easy assembly, click systems are one possibility.

[0048] It is possible to connect the connecting elements additionally or exclusively by gluing and / or welding.

[0049] It may be provided that at least one connecting element of a first frame profile element and at least one connecting element of a further frame profile element form a force-fit and / or form-fit connection.

[0050] The formation of a force-fit and / or form-fit connection between the connecting elements of the frame profile elements can enable high stability and strength of the entire frame device.

[0051] This type of connection preferably allows the frame profile elements to be securely joined without the need for additional fasteners. This simplifies assembly and promotes the reusability of the frame profile elements, contributing to sustainable and resource-efficient construction.

[0052] However, it may also be possible, in addition or as an alternative, to connect the connecting elements using other types of connection, such as gluing and / or welding.

[0053] For the purposes of this disclosure, a positive-locking connection means a mechanical connection in which the shape of the connected connecting elements is designed in such a way that they enable a stable and firm connection of the frame profile elements without additional fasteners.

[0054] The primary connection section may be designed to be detachable from the frame profile element, whereby the separation process of the primary connection section from the frame profile element exposes the secondary connection section radially outwards. This allows the secondary connection section to form a new outer surface of the frame profile element in place of the secondary connection section.

[0055] The separation of the primary connection section and the exposure of the secondary connection section have the technical effect of providing a new outer surface of the frame profile element, which is ready for further use.

[0056] For example, the frame device can be provided as a module of a car body structure and / or be reused, serving as a supporting structure to reinforce the car construction, thereby improving the structural integrity of the entire structure.

[0057] For the purposes of this disclosure, separation means the mechanical process by which the primary connecting section is removed from the frame profile element in order to expose the secondary connecting section.

[0058] For the purposes of this disclosure, a force-fit connection means a connection in which the connected frame profile elements, or the primary and secondary connection sections, are held together by applied forces, for example by clamping.

[0059] It may be provided that the frame profile elements are extruded profiles.

[0060] The use of extruded profiles as frame profile elements has the technical advantage that these profiles are particularly light and stable at the same time.

[0061] The extrusion process allows for the creation of complex cross-sections that enable optimal adaptation to the structural requirements of the frame device.

[0062] Furthermore, the use of extruded profiles promotes the reusability of the frame construction, as the frame profile elements can be disassembled and reused through the secondary use section, for example as modules for a car body structure of a construction and / or residential container.

[0063] An extruded profile is an elongated structural element produced by extrusion, with a particularly constant cross-section, which can be used for the production, reinforcement and stabilization of load-bearing structures.

[0064] It may be provided that at least one frame profile element comprises or is made of aluminium.

[0065] The use of aluminium as a material for the frame profile elements offers the advantage that the material is lightweight yet has high strength.

[0066] Aluminum can have high corrosion resistance, which increases the lifespan of the frame and allows for its secondary use even in harsh environments. Furthermore, aluminum is particularly easy to recycle.

[0067] Other possible compositions may include mixtures with other metals such as magnesium or zinc to further optimize the specific properties.

[0068] It may be provided that at least three frame profile elements form a triangular frame around the inner area. It may also be provided that at least four frame profile elements form a square or trapezoidal frame around the inner area.

[0069] This shape preferably allows for an even load distribution and / or can be adapted to various structural requirements.

[0070] For the purposes of this disclosure, a triangular frame can be understood as an arrangement consisting of three frame profile elements which together enclose the interior and form a stable triangular structure.

[0071] The frame device in triangular shape or with triangular geometry can, for example, be used as a module for recycling.

[0072] A square or trapezoidal frame, as defined in the present disclosure, can refer to a structure formed from at least four frame profile elements.

[0073] The square or trapezoidal frame can also serve as a reusable module, for example for a car body structure.

[0074] Complex overall structures can be realized through suitable combination of frames of different shapes or geometries, such as triangles, quadrilaterals and polygons.

[0075] This allows for the mapping of load paths optimized for the load flow. Each individual module can offer a wide range of optimization potential.

[0076] For example, the interior area of ​​the frame device enclosed by frame profile elements can be additionally filled.

[0077] The interior of the frame device may include or be formed from a sandwich element, a sheet metal panel, and / or a window made of glass, plexiglass, or another transparent material. This preferably increases the structural integrity and functionality of the device.

[0078] For the purposes of this disclosure, a window made of glass, plexiglass or another transparent material means a light-transmitting component that can be integrated into the interior of the frame device to allow natural lighting of an interior space of the overall structure to be manufactured.

[0079] The transparent material can be, for example, polycarbonate, acrylic, or an optionally coated glass to optimize both stability and light transmission.

[0080] By using a window, the frame device can be adapted to applications where light transmission is advantageous, thereby increasing the versatility of the design, for example as a load-bearing structure in a car body.

[0081] For the purposes of this disclosure, a sandwich element can be understood as a multi-layered structure consisting of two cover layers and a core material.

[0082] The outer layers can be made of metal, such as aluminum, or fiber-reinforced plastic, while the core material is made of foam or a lightweight insulating material to provide both mechanical stability and good thermal and / or acoustic insulation.

[0083] According to the present invention, a method for reusing a frame device as described in the present disclosure is also provided.

[0084] For example, a primary connection section can be separated from a frame profile element. This may expose the secondary connection section of the frame profile element.

[0085] Subsequently, two frame profile elements can be connected to each other, for example by means of their secondary connecting sections.

[0086] The method for reusing the frame device has the technical effect that the primary connection sections can be removed and the secondary connection sections exposed.

[0087] This allows the frame profile elements to be reused in a recycled frame device, for example, a load-bearing structure of a construction and / or residential container.

[0088] The frame structure can be designed as a module. In particular, several identical modules and / or several modules of different design, shape and / or size can be used to produce a load-bearing structure.

[0089] For the purposes of this disclosure, separation means the mechanical process by which the primary connecting section is removed along the longitudinal axis of the frame profile element in order to expose the secondary connecting section.

[0090] Separation can include mechanical separation, such as "sawing", "cutting", "milling", etc., as well as "laser cutting", etc.

[0091] The term exposure refers to the process of making the secondary connecting segment accessible after and / or by removing the primary connecting segment.

[0092] Joining refers to the creation of a mechanical connection between two frame profile elements via their secondary connection sections, for example via the inner profile or through form-fitting profiles, such as connecting elements that interlock precisely, like tongue and groove profiles, to create a stable and reusable frame construction.

[0093] It may be provided that the connection of two frame profile elements is carried out by means of at least one frame profile connecting element and / or at least one connecting element of the frame profile elements.

[0094] Different connecting elements can enable an adaptable and modular design, where the frame profile elements can be efficiently connected to meet the specific requirements of the respective application.

[0095] A frame profile connector is a component specifically designed for the mechanical connection of at least two frame profile elements. It can have various shapes to ensure a stable connection.

[0096] The term "connecting element" as used in this disclosure can refer to a component used to connect two frame profile elements, for example, to couple them. This can be achieved by positive locking, force locking, or material locking connections, depending on the requirements of the specific application.

[0097] The placement of a frame profile connecting element after separating the primary connection section has the technical effect of further strengthening the stabilized connection of the frame profile elements.

[0098] For example, it can be used to cover and / or bridge a gap between two secondary connecting sections of two frame profile elements.

[0099] By using the frame profile connecting element, the frame profile elements can be firmly connected to each other, in particular by form-fitting, force-fitting and / or material-fitting connection, thereby creating a connection that contributes to the structural integrity of the entire construction.

[0100] It may be provided that at least one frame profile connecting element is designed as an H-profile, additional profile or connecting plate.

[0101] Different frame profile connecting elements preferably make it possible to adapt the frame device to specific requirements and thereby ensure a stable and efficient connection.

[0102] An H-profile within the meaning of the present disclosure is a frame profile connecting element with an H-shaped cross-sectional geometry, which is used to connect frame profile elements in order to ensure a particularly stable and positive-locking connection.

[0103] For the purposes of this disclosure, the term "additional profile" refers to an additional profile that is inserted into or placed on the secondary connection sections to reinforce and / or adapt the frame profile elements, for example, the connecting elements. This can increase the structural integrity of interconnected frame profile elements.

[0104] A connecting plate is a flat connecting element used to join two or more frame profile elements at the secondary connection points. This creates a strong and stable load-bearing structure. The connection can be made, for example, by welding or gluing.

[0105] All embodiments of the frame profile connecting element can be combined with all embodiments of the secondary connection sections, especially with the internal profiles and the connecting elements. These combinations preferably support and / or enable a flexible and stable connection structure that can be adapted according to structural requirements.

[0106] In another embodiment, it may be provided that several frame devices are used to manufacture a load-bearing structure.

[0107] For example, the supporting structure can be part of a construction and / or residential container. The frame components can be connected to each other using the secondary connection sections.

[0108] The use of multiple frame devices to produce a load-bearing structure has the technical effect of achieving a modular and stable construction.

[0109] The connection of the frame devices via the secondary connection sections enables quick and efficient assembly, which can be advantageous for secondary use, for example, the reuse of the frame device as a load-bearing structure for construction and residential containers.

[0110] A frame device within the meaning of the present disclosure is preferably a modular unit consisting of several frame profile elements and serving to form a stable and load-bearing structure.

[0111] The above can be summarized in other words as a possible more concrete elaboration of the revelation, as described below.

[0112] Designing car body structures to optimize load flow offers significant potential for lightweight construction. However, translating load paths derived, for example, from topology optimization into a design that is cost-effective and manufacturable is often challenging. The present invention aims to resolve this conflict through a modular design of the side wall, floor, or roof structure. This approach allows for the selection of load paths and materials within specific geometric constraints. Furthermore, changes in thickness within the structure can be implemented to further enhance the lightweight potential. Additionally, a multi-material design can be easily implemented, thereby facilitating the use of new (e.g., more sustainable) materials.

[0113] Car body structures can be manufactured from materials such as aluminum or steel. For aluminum construction, extruded aluminum profiles are used. Aluminum blocks are pressed through dies to create semi-finished products several meters long, and these extruded profiles are then assembled to form a car body. The extruded profile serves both a load-bearing and cladding function, which is why its cross-section must be designed to withstand the maximum load. Due to the extrusion process, only constant cross-sections are possible in the extrusion direction. Windows and doors are subsequently cut into the assembled semi-finished products. Despite the high material and tooling costs, this technology is predominantly used due to its high degree of automation. Steel, on the other hand, is frequently used as a construction material for small production runs because the initial costs of integral construction are high.This often involves cladding a substructure made of semi-finished steel products with appropriate sheet metal.

[0114] Established construction methods are optimized with regard to service life and the existing manufacturing infrastructure of the respective rail vehicle manufacturers. Lightweight construction potential also plays an important role in development – ​​however, this optimization takes place within the existing concepts for the car body structure. Since the state of the art predominantly relies on semi-finished products several meters long, representing individual, especially diagonally running, load paths and combining different materials is difficult. Furthermore, the generally preferred integral aluminum construction does not allow for cross-sectional adjustment of the semi-finished products. This necessitates adapting the cross-sections to the maximum loads, resulting in a disproportionately robust structure in less stressed areas.For these reasons, modern railcar bodies are structurally over-engineered and cannot fully exploit their lightweight construction potential. This leads to poorer payload and energy efficiency of the rail vehicle.

[0115] By combining standardized elements, hereinafter also referred to as segments or frame components, in simple geometries (e.g., triangles, quadrilaterals), more complex structures can be built. This allows for the creation of load paths optimized for load flow. Each individual segment or frame component offers a wide range of optimization potential. For example, the internal panels can be made of sandwich panels with a foam core, a wood core, or a structured core made of various materials such as natural materials or polymers. This approach allows the segments to be adapted to the respective local loads and requirements, thereby achieving a weight advantage compared to other construction methods.The novel construction method, through the locally adapted use of materials and the possibility of realizing the internal panels with sustainable materials, enables a more resource-efficient construction compared to the state of the art. According to the present disclosure, the standardized elements can be used to construct a load-flow-optimized side wall, ceiling, or floor structure. The elements used consist of an internal panel within the frame structure, which can, for example, be made of a sandwich panel, and a frame structure, such as the frame fixture itself, made of extruded aluminum profiles. The individual standardized elements can be connected to one another using various methods. For quick and easy assembly, click systems combined with gluing or welding are possible, for example.The joined frame elements, for example the frame profile elements, of the individual segments or the frame device simultaneously form the main load paths and thus enable an integrative approach.

[0116] For example, a side wall can form a single segment. A sandwich material can be provided as an inner panel in the interior of the segment or frame structure, and extruded profiles, such as frame profile elements, can form a reusable frame structure around the interior.

[0117] The above-mentioned designs and further developments can be combined with one another as appropriate. Further possible designs, further developments, and implementations of the revelation also include combinations of previously or subsequently described features of the revelation that are not explicitly mentioned.

[0118] In particular, the person skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the present disclosure. Specifically, features of the device claims can be implemented and / or carried out by corresponding functions, thereby supplementing or extending the method.

[0119] Furthermore, process steps can be implemented and / or specified through corresponding features of the device. Thus, what was described above with reference to the device also applies analogously to the process and vice versa.

[0120] Further details and advantages of the invention will now be explained in more detail with reference to the exemplary embodiments shown in the drawings.

[0121] They show: Fig. 1 a schematic representation of a first embodiment of a frame device; Fig. 2 a schematic representation of two frame devices according to the first embodiment; Fig. 3 a schematic representation of a cross-section of an embodiment of the frame profile element; Fig. 4 a schematic representation of the cross-section of an alternative frame profile element; Fig. 5 a schematic representation of a cross-section through two interconnected frame profile elements; Fig. 6 a schematic representation of a cross-section through two interconnected frame profile elements according to a third embodiment; Fig. 7 a schematic representation of a cross-section through two interconnected frame profile elements of a fourth embodiment; Fig. 8 a schematic representation of part of a load-bearing structure composed of several frame devices; and Fig. 9 a flowchart to illustrate a procedure in accordance with the disclosure.

[0122] The accompanying drawings are intended to provide a further understanding of the disclosure. They illustrate optional developments and serve to explain the principles and concepts of the disclosure. Other developments and many of the mentioned features and / or advantages become apparent with reference to the drawings. The elements of the drawings are not necessarily shown to scale. All features and / or advantages, individually and / or in any combination, are suitable for further specifying the invention within the scope of protection defined by the claims.

[0123] In the figures, identical, functionally equivalent, and / or similarly acting elements, features and components are each provided with the same reference symbols, unless otherwise stated.

[0124] Fig. Figure 1 shows a schematic representation of a first embodiment of the frame device 100, consisting of at least two frame profile elements 110 and an interior area 120.

[0125] In Fig. Figure 1 shows three frame profile elements 110 forming a triangular frame device 100.

[0126] For example, the frame device 100 is a right-angled, triangular frame device 100 with a 90° angle between two profile elements 110, which form the legs 111, 112 of the triangle.

[0127] For example, the legs 111, 112 are of equal length and together with a third profile frame element 113 form an isosceles triangular frame device 100.

[0128] The third profile frame element 113 forms the hypotenuse of the triangular frame device 100.

[0129] The interior area 120 is in Fig. 1 shown hatched.

[0130] The interior area 120 of the frame device 100 is the area enclosed by the triangular frame device 100, in particular by the frame profile elements 110, for example the frame profile elements 111, 112, 113.

[0131] The interior space of 120 can be filled, for example with one or more sandwich panels. A sandwich panel can, for example, comprise a foam core, a wooden core, and / or a structured core made of one or more materials, which can lead to a weight advantage compared to other construction methods.

[0132] The structured core can, for example, consist of a wavy, honeycomb-shaped or ribbed material.

[0133] The interior area 120 of the frame device 100 can be fitted with a sandwich element, a sheet metal plate or a window.

[0134] The window may include or consist of glass, plexiglass, or another transparent material.

[0135] The in Fig. The form of the frame device 100 shown is not limited to triangles; rather, the arrangement of the frame profile elements 110 in a rectangular or trapezoidal shape or any other polygonal frame shape is also possible.

[0136] Fig. Figure 2 shows two frame devices 101, 102 which are opposite each other with their connecting sections.

[0137] The two frame devices 101, 102 can be connected to each other to form a load-bearing structure, for example a square module, by means of primary connecting sections 140 or also by means of secondary connecting sections 130.

[0138] According to a first use, the connection is made by means of primary connection sections 140 of frame profile elements 110 designated 113, 115. The outer sides of the frame devices 101, 102 facing each other can, for example, be welded together for this purpose.

[0139] For later reuse, the weld area, i.e. the primary connection sections 140, is separated, for example by sawing or cutting out.

[0140] This results in frame profile elements 113, 115 of the frame devices 101, 102, each of which has an exposed secondary connection section 131, 132.

[0141] While the frame profile elements 113, 115 of the frame device 101, 102 are connected to each other with the primary connection sections 140, the secondary connection sections 130 (131, 132) are therefore not yet exposed.

[0142] Thus, several frame devices 100 can be reused after initial use, for example to produce a load-bearing structure, e.g., a construction and / or residential container, by making a new connection between several frame devices 101, 102 using the secondary connection sections 130.

[0143] Fig. Figure 3 shows a cross-section through the frame profile element 110 along the section line 119. Fig. 1.

[0144] The frame profile element 110 shown has both a primary connection section 140 and a secondary connection section 130.

[0145] These connecting sections 130, 140 are arranged radially with respect to the inner area 120.

[0146] In Fig. The direction arrow 150 points from the inner area 120 towards the primary connection section 140. This means that the primary connection section 140 is located radially further outwards and the secondary connection section 130 is located radially inwards from the primary connection section 140.

[0147] In this configuration, the structure of the frame profile element 110 enables a connection with another frame profile element 110, initially via the primary connection section 140.

[0148] The connection via the primary connection section 140 serves a primary purpose.

[0149] The secondary connection section 130 is in Fig. 3 not exposed.

[0150] The secondary connection section 130 is thus well protected inside the frame profile element 110 during its primary use.

[0151] The frame profile element 110 forms an internal profile 135 in the secondary connection section 130.

[0152] The internal profile has one or more connecting elements 160.

[0153] Fig. Figure 3 shows the inner profile 135 with, for example, two connecting elements 160 in the secondary connection section 130. One of the connecting elements 160 is C-shaped. The other connecting element 160 is complementary to it.

[0154] The in Fig. The embodiment of the frame profile element 110 shown in Figure 4 corresponds in terms of structure and function to the one described in the Fig. The embodiment shown in Figure 3 is identical, so reference is made to its preceding description. The following refers to Fig. The description in section 4 also applies to the frame profile element 110 with regard to its structure and function. Fig. 3.

[0155] For the frame profile elements 110 in the Fig. 3 and Fig. 4. For example, the frame profile elements 113 and 115 of the frame devices 101 and 102 may be involved.

[0156] The frame profile element 110 in Fig. 4 corresponds to the one in Fig. 3, but is rotated by 180°.

[0157] According to Fig. 4 This inner profile 135 has two connecting elements 161, 162 in the secondary connecting section 130.

[0158] The connecting element 161 is C-shaped and suitable for connecting the complementary connecting element 162 of a counterpart, in particular of another frame profile element 110, for example made of Fig. 3, to record.

[0159] The connecting elements 160, 161 and 162 in the Fig. 3 and Fig. The four are therefore complementary to each other.

[0160] As in Fig. 5. The connecting elements 160, 161, 162 can be shown in more detail. Fig. 3, Fig. 4. A positive-locking connection is formed as soon as the respective primary connection section 140 has been removed. The connecting elements 160, 161, 162 are for this purpose in particular clipped or snapped together or positively locked together by lateral insertion.

[0161] Additionally, frame profile connecting elements 171, 172 can be attached to the outer sides 138, 139 of the frame profile elements 113, 115.

[0162] The frame profile connecting elements 171, 172 contribute to reinforcing the connection between the frame profile elements 113, 115. They can also bridge and / or cover unwanted openings or gaps between the frame profile elements 110.

[0163] The frame profile connecting elements 171, 172 reinforce the interconnected frame profile elements 110 by means of a force-fit and / or form-fit and / or material-fit connection.

[0164] For example, welding or adhesive bonding can be used for this purpose.

[0165] The frame profile connecting elements 171, 172 preferably extend at least approximately over the entire length of the frame profile elements 110, 113, 115.

[0166] The frame profile connecting elements 171, 172 preferably run parallel to the longitudinal axis of the frame profile elements 110, 113, 115, in particular perpendicular to the image plane. Fig. 5.

[0167] Fig. Figure 6 shows a cross-section through two interconnected frame profile elements 111, 112 according to a third embodiment.

[0168] The frame profile elements 110, 113, 115 include a secondary connecting section 130 which is exposed.

[0169] The secondary connection sections 130 comprise according to Fig. 6 no interlocking connecting elements.

[0170] Rather, only internal profiles 135 are provided.

[0171] The outer side surfaces or outer sides of the frame profile elements 138, 139 define the outer contour of the frame profile elements 113 and 115.

[0172] Frame profile connecting elements 170 are provided for connection, which are H-shaped in cross-section, with an outer web 176 and an inner web 175 as well as a central web 177, which connects the outer web 176 with the inner web 175.

[0173] The outer web 176 is wider than the inner web 175.

[0174] The outer web 176 lies on the outer side surface 138, 139 of the frame profile elements 113, 115.

[0175] The inner web 175 abuts the inner profiles 135 and ensures a constant distance between the frame profile elements 113, 115.

[0176] The width of the inner web 175 can also be designed such that the frame profile elements 113, 115 come into direct contact with each other.

[0177] The frame profile connecting elements 170 are arranged in the space between the secondary connecting sections 130 of the frame profile elements 113, 115.

[0178] This construction method enables increased structural strength and reusability of the frame profile elements 110 in the frame device 110 of a load-bearing structure, e.g. a construction and / or residential container.

[0179] The frame profile connecting elements 170 between the frame profile elements 113, 115 provide additional stiffening, which can further support the overall integrity of the construction.

[0180] Fig. Figure 7 shows a cross-section of two interconnected frame profile elements 113 and 115 according to a fourth embodiment.

[0181] Both frame profile elements 113, 115 each include secondary connection sections 130 which are exposed.

[0182] A frame profile connecting element 170 is provided for the connection, which is designed as an additional profile.

[0183] The frame profile connecting element 170 is monolithic. As in Fig. As shown in Figure 7, monolithic can also mean an internal structure with cavities, similar to an extruded profile.

[0184] Monolithic is not limited to a full profile.

[0185] The frame profile connecting element 170 has two outer webs 176 and a central web 177, as well as an inner web 175 which is formed around a central area of ​​the central web 177.

[0186] Connecting elements 163 of the frame profile elements 113, 115 enable a fixed mechanical connection with the inner web 175 of the frame profile connecting element 170 as an additional profile.

[0187] The connecting elements 163, together with the frame profile connecting element 170, create a positive-locking coupling that establishes a secure, reusable connection between the frame profile elements 113 and 115. The connection is, in particular, a dovetail joint or a tongue-and-groove joint.

[0188] This configuration ensures a modular and robust load-bearing structure that can be adapted to changing requirements and promotes reusability.

[0189] Thus, this fourth embodiment, like all other embodiments, enables flexible adaptation to various structural requirements, especially in lightweight construction, and allows for resource-saving reusability of the frame device 100, in that the frame profile elements 110 can be reused after separation of the primary connection sections 140 by means of the secondary connection sections 130.

[0190] In the embodiments of the Fig. 5, Fig. 6 and Fig. Figure 7 illustrates how the secondary connection sections 130 and the frame profile connecting elements 170, 171, 172 interact to create a positive-locking, force-locking, and / or material-locking connection. The connecting elements 160 in the secondary connection sections 130 ensure a secure mechanical coupling that remains stable even under load. Alternatively or additionally, the frame profile connecting elements 170, 171, 172 provide a positive-locking, force-locking, and / or material-locking connection of the frame profile elements 110.

[0191] All embodiments of the frame profile connecting element 170 can be combined with all embodiments of the secondary connecting sections 130, in particular with the internal profiles 135 and the connecting elements 160. These combinations support a flexible and stable connection structure that can be adapted according to structural requirements.

[0192] Fig. Figure 8 shows part of a supporting structure comprising several frame devices 100, each consisting of different frame profile elements.

[0193] Several frame devices have 100 triangular geometries and other frame devices have 100 square geometries in order to create a stable supporting structure overall.

[0194] Connections are provided using the primary connection sections 140. For further use of the frame devices 100, only the connection sections 140 need to be cut out so that the frame devices 100 can be assembled into a new structure.

[0195] The representation in Fig. 8 highlights the modularity of the construction and clarifies that the frame devices 100 can be easily joined together to meet various requirements in construction, for example as a load-bearing structure of a wagon body structure or as a wall of a construction and / or residential container.

[0196] The modular arrangement allows for load path distribution via the frame devices. This enables flexible adjustment of the load paths.

[0197] Fig. Figure 9 shows a flowchart of a process 200 for the reuse of a modular frame device.

[0198] The process begins with the separation 210 of a primary connection section from a frame profile element 110.

[0199] The separation 210 takes place along a longitudinal axis of the frame profile element 110.

[0200] This step of separating 210 makes a secondary connection section 130 accessible, which thus means an exposure 220 of the secondary connection section 130.

[0201] In the next step, 230 of two frame profile elements 110 are connected by means of their exposed secondary connection sections 130.

[0202] Optionally, in step 240 at least one frame profile connecting element 170 is fixed, either within or between the secondary connecting sections 130 of two frame profile elements 110.

[0203] Finally, in step 250, a material-bonded and / or force-bonded and / or form-bonded connection is formed at the secondary connection sections 130, optionally using one or more frame profile connection elements 170. This connection ensures a strong and load-bearing structure.

[0204] This process simplifies the dismantling and reuse of the frame profile elements, thus enabling a sustainable and resource-saving construction method.

[0205] Furthermore, this sequence allows for the reuse of the frame device and promotes a modular design for flexible adjustment of the load paths.
