Two-part fastening device for attaching a wall element to a base plate, as well as arrangement and method

Description

[0001] The invention relates to a fastening device for attaching a wall element to a base plate.

[0002] Furthermore, the invention relates to an arrangement comprising a wall element and a base plate. The invention also relates to a method for attaching a wall element to a base plate.

[0003] Prefabricated parts and components are being used more and more frequently in the construction industry. For example, wooden components for walls, ceilings, or floors can be prefabricated in a factory and delivered to a construction site for final assembly. This is particularly common in the production of prefabricated houses. Such a prefabricated house has a construction similar to a traditional wooden house. The individual walls or wall elements, floors or floor elements, and ceilings or ceiling elements can be made at least partially of wood. Various fastening and connection methods can be used to attach the individual elements or wooden components during assembly. For example, brackets or angle connectors are used to attach a wall element to a floor slab.These are screwed onto a floor element after a wall element has been positioned.

[0004] However, a disadvantage is that these angle brackets or mounting brackets cannot be attached during pre-assembly or prefabrication, as they would otherwise protrude from the wooden components or elements during transport, potentially causing damage. This, in turn, makes subsequent assembly more difficult, since fastening can only be carried out after a wall element has been positioned on a base plate.

[0005] US Patent 3,322,879 A discloses a soundproof, double-insulated, electrically shielded space whose panel frames have crossbeams that are significantly thinner than the edge elements. Sound insulation is incorporated within these frames, so that the metallic shielding material on opposite sides of the panel is supported only by the frame elements and the insulation and does not come into contact with the crossbeams. Compressible sound insulation is also located between the edges of the panel frames, which limits vibrations within the panel to subsonic levels and prevents them from being transmitted from frame to frame.

[0006] US 3,113,358 A discloses an attachable clip for supporting and fastening two adjacent planar structures, wherein the clip consists of two elements formed from rigid material, one of the elements being attached to a planar structure to be joined beside its edge, and forming with the planar structure a pair of spaced-apart, generally adjacent pockets open beside the edge of one planar structure, one of the pockets being provided with a concave surface zone, and the other of the elements being attached to the other planar element and having outwardly projecting leg elements capable of penetrating the pockets formed by one element, and wherein a convex surface zone on one of the leg elements engages with the concave surface zone of one element.

[0007] One object of the present invention is to make it easier to mount a wooden component, such as a wall element, onto a base plate or floor element.

[0008] This problem is solved by a fastening device, an arrangement, and a method according to the independent claims. Meaningful further developments arise from the dependent claims.

[0009] One aspect (first aspect) relates to a fastening device having the features of claim 1.

[0010] The proposed fastening device simplifies and improves the process of attaching a wall element to a base plate. The separate components of the fastening device allow, for example, the tension plate to be attached during the wall element's manufacturing process at the factory. This means the tension plate can be pre-mounted on the wall element, simplifying transport, especially to a construction site.

[0011] The fastening device according to the invention or proposed can be used particularly advantageously in timber structures. The proposed fastening device can also be used advantageously in the assembly of a prefabricated house, a building, a load-bearing structure, a solid construction house, or a timber house.

[0012] In particular, the wall element can be a wooden component or a wooden wall of a prefabricated or timber-framed house. The base plate can be, for example, a floor element, a ceiling element, or a foundation of a prefabricated or timber-framed house, or any other structure. Specifically, the base plate can be a horizontally oriented floor or foundation slab of a prefabricated house. The wall element can then be attached vertically to this base plate.

[0013] The tension plate and the base plate can be two separate units. In particular, the tension plate and the base plate can be physically separate from each other. In other words, the fastening device can be designed in two parts: the tension plate and the base plate. This two-part design allows the tension plate and / or the base plate to be attached in advance, i.e., during pre-assembly of the wall element and / or the base plate. This offers advantages during assembly, especially when attaching the wall element to the base plate on a prefabricated house construction site.

[0014] The tension plate and the base plate can be made of the same material. In particular, the tension plate and the base plate can be metallic components. It is also conceivable that the material of the tension plate and the base plate can be any type. However, the tension plate and the base plate must be made of a material suitable for stable assembly and fastening in timber structures or other prefabricated houses.

[0015] The base plate can have several coupling elements, i.e., connecting elements, designed to be coupled and thus connected to the counter-coupling elements of the tension plate. The coupling elements correspond to or are complementary to the counter-coupling elements, so that in the coupled state of the coupling elements and the counter-coupling elements, the tension plate can be positively connected to the base plate. A releasable positive connection can be achieved. This positive connection of the tension plate to the base plate allows the wall element to be attached to the base plate during assembly. Specifically, a positive connection exists in at least four, and in particular five, spatial directions. In other words, a coupling element can be moved from the coupled state to an uncoupled state by a movement opposite to the movement of the linear second component.Consequently, in the coupled state, the coupling elements cannot be pulled out of the opposing coupling elements or moved downwards, i.e., towards the base plate. Optionally, decoupling can be achieved by moving them upwards, i.e., away from the base plate.

[0016] Furthermore, the base plate can be attached to the base plate in the direction of the linear second component using the connecting element, which can be a fastener. This allows the coupling elements to be connected to the counter-coupling elements, so that the base plate and the tension plate are designed as a single unit.

[0017] The movement with the linear second component can be a movement or sequence of movements parallel to the main extension plane of the tension plate.

[0018] The coupling of the coupling elements with the counter-coupling elements is achieved through a two-part movement sequence. In addition to the movement of the linear second component, the coupling elements can also move along a linear first component. The movement with the linear second component (i.e., a second movement component) can be parallel to the main plane of extension of the tension plate. The movement with the linear first component (i.e., a first movement component) can be perpendicular to the movement of the linear first component, i.e., perpendicular to the main plane of extension of the tension plate.

[0019] For example, the first movement, or the first step of the linear motion, can be a horizontal movement of the coupling elements relative to the drawbar, moving them towards the counter-coupling elements. Following this initial horizontal movement, a vertical movement of the coupling elements can then occur. This two-part movement, or rather the split motion sequence for coupling, allows for a simple yet secure and stable connection between the coupling elements and the counter-coupling elements.

[0020] In particular, the drawbar has an L-shaped form when coupled to the base plate. In other words, when coupled, the fastening device is L-shaped, such that the drawbar and base plate are perpendicular to each other.

[0021] Specifically, in the coupled state, the tension plate is arranged perpendicular to the base plate, so that the wall element and the base plate are also arranged or positioned perpendicular to each other.

[0022] Optionally, the fastening device can be designed as a mounting bracket or angle connector when the base plate is coupled to the tension plate. Accordingly, a two-part or multi-part angle connector or mounting bracket can be realized using the fastening device according to the invention. This can be particularly advantageous in the assembly of a prefabricated house or timber structure, since elements such as timber components can be more easily assembled or fastened by construction workers or tradespeople using the fastening device according to the invention.

[0023] In particular, the fastening device can be a mechanical unit or a mechanical assembly. The coupling elements are connected to the opposing coupling elements by a mechanical coupling.

[0024] In one embodiment, the tension plate is designed to be entirely plate-shaped. In other words, the tension plate can be designed as a plate or as a flat, planar, or even sheet metal. In particular, the tension plate is completely flat. This design allows the tension plate to be positioned and attached flush against the wall element. This advantageously allows the tension plate to be attached to the wall element during a manufacturing or prefabrication process. Due to its plate-like design, no parts, pieces, or elements protrude from the tension plate that could pose a hazard or cause damage, especially during transport of the wall element.

[0025] In one embodiment, the tension plate has several recesses, into which screw elements can be inserted to fasten the tension plate to the wall element. The tension plate, which is particularly flat and plate-shaped, can be attached to the wall element by means of screw elements that can be inserted or inserted into the recesses. In other words, the several recesses can be pre-drilled holes or holes through which the tension plate can be fastened, especially screwed, to the wall element using screw elements or fasteners such as bolts, screws, or nails. The several recesses can be arranged differently or evenly distributed on the tension plate.In particular, the drawplate can have several equally distributed and, in particular, spaced-apart depressions.

[0026] The dimensions or size of the tension plate and the base plate can be varied. In particular, the length of the tension plate and especially the size or extent of the base plate can be adapted to the specific application and especially to the dimensions of the wall element and the base plate.

[0027] In one embodiment, the base plate has a base and two wall sides, with the wall sides being arranged on opposite outer surfaces of the base plate. When the base plate is connected to the tension plate as intended, the two wall sides extend perpendicular to the tension plate. In other words, the base plate can be designed like a shoe. The two wall sides, or outer walls, increase the stability of the base plate and thus of the fastening device. This also affects the stability of the wall element's attachment to the base plate. The base plate can rest against the base plate and be fastened to it by means of the connecting element. Alternatively, the wall sides of the base plate can project upwards from the base plate and thus from the base plate.In particular, the sides of the base plate can be arranged vertically or perpendicular to the base plate. The sides of the base plate can be arranged or attached to opposite outer surfaces or opposite outer edges of the base plate. When the base plate is connected or coupled to the tension plate as intended, the two sides of the base plate can extend perpendicularly to the tension plate and thus to the wall element.

[0028] The base plate can, for example, be manufactured as a single piece, so that in a single manufacturing process using a metallic material, the base plate and the two side walls are produced together. It is also conceivable that the two side walls are subsequently attached to the base plate. In this case, for example, the two side walls can be welded to the base plate. Alternatively, the side walls could be manufactured by bending or rolling.

[0029] Additionally or instead, the sides of the base plate wall panels can form a guide element. This is particularly advantageous when, after mounting one wall panel to the base plate, another wall panel is attached to the previously mounted wall panel. To achieve this, the wall panel can be inserted into a corner of a house or room, allowing the additional wall panel to be inserted between the sides of the base plate wall panels at the corner where two wall panels meet.

[0030] In one embodiment, the base plate has a mounting side which, when the base plate is connected to the drawbar as intended, rests against the drawbar. Coupling elements are arranged at the end regions of the base plate wall surfaces that extend along the mounting side. During the linear movement of the coupling element towards the opposing coupling elements, the mounting side faces the drawbar and thus the wall element. In other words, the mounting side is the front of the base plate, which, in the coupled state, rests directly against the drawbar. The mounting side can accordingly include the coupling elements. Coupling elements can be attached to, mounted on, or arranged at each end region of the base plate wall surfaces.When the floor plate is coupled to the drawbar, the end areas of the floor plate wall sides are directed towards the drawbar and thus towards the wall element.

[0031] In one embodiment, the sides of the base plate are ramped, with the height of each side increasing towards the mounting side. Thus, the walls of the base plate can each be designed as a ramp, with these ramped sides reaching their highest point at the ends. Accordingly, the ramp begins on the side, particularly the rear side, of the base plate opposite the mounting side and therefore opposite the tension plate. The ramped sides of the base plate thus begin to increase in height, i.e., vertically, at this point. This ramped design increases the stability of the mounting device.

[0032] In one embodiment, the coupling elements are designed as connecting hooks, with the connecting hooks arranged at their ends angled towards the base plate. In other words, the connecting hooks, or metallic hook elements, are perpendicular, so that the respective hook-shaped element is open towards the base plate, and the hooks are angled such that one end of the hook points towards the base plate. The mating coupling elements can be designed such that the connecting hooks can be engaged with them, thus forming a hook-in function.

[0033] For example, the feedback elements can be receiving areas such as rectangular openings. During linear movement, the coupling elements, designed as connecting hooks, can be hooked into the feedback elements, which are designed as receiving areas. The connecting hooks can be inserted into the feedback elements in the direction of the first linear component, thus passing through them to couple the base plate to the draw plate via an engagement function.

[0034] In one embodiment, two connecting hooks are arranged one above the other at the end regions of the base plate wall sides. Thus, at least two connecting hooks can be arranged one above the other at the end regions of the base plate wall sides, which are particularly ramp-shaped. It is also conceivable that one, two, or more connecting hooks are arranged at each end region. Depending on the specific fastening situation of the wall element, the fastening device can be designed accordingly. A stable and secure coupling of the base plate to the tension plate can be achieved by means of two connecting hooks arranged one above the other. In particular, the connecting hooks project forward from the end regions, i.e., towards the tension plate, during a normal coupling process.This allows an interlocking function or interlocking functionality to be realized or implemented between the coupling elements and the negative feedback elements.

[0035] In one embodiment, two of the multiple feedback elements are arranged on the drawbar in a manner analogous to the two vertically spaced connecting hooks, allowing the connecting hooks to be engaged in the feedback elements. The feedback elements are also arranged vertically and spaced apart, maintaining the same distance from each other as the corresponding two vertically spaced connecting hooks. This analogous arrangement of the coupling elements and feedback elements enables a reliable and simple coupling process. In other words, the connecting hooks can be inserted into the feedback elements, which are designed as openings, and thus engaged, particularly by moving the linear second component.For this purpose, the coupling elements and the counter-coupling elements must be arranged analogously or correspondingly to each other on the drawbar and, accordingly, on the base plate in order to carry out the corresponding coupling process. In one embodiment, the connecting element is designed as a bore hole which is arranged within the base of the base plate in order to fasten the base plate to the base plate by means of a screw element or bolt element.

[0036] For example, the connecting element, designed as a drilled hole or opening, can be positioned or formed centrally on the base plate. In other words, the base plate can have the connecting element in its center. It is also conceivable that several connecting elements and correspondingly several drilled holes are pre-drilled or pre-fabricated within the base plate, so that, depending on the application and especially the installation situation, the base plate can be attached to the base plate, particularly by screws.

[0037] A further aspect (second aspect) of the invention relates to an arrangement comprising a wall element and a base plate, wherein the wall element and the base plate are fastened by means of at least one fastening device according to the previous aspect or an advantageous embodiment thereof. In particular, the arrangement can be a component of a house, prefabricated house, timber frame, wooden house, or other load-bearing structure. For this purpose, walls or wall elements or components of, for example, the prefabricated house can be fastened to the base plate or to a ceiling element by means of the fastening device according to the invention. One or more fastening devices can be used for this purpose.

[0038] In one embodiment of the second aspect, the tension plate is attached to the wall element and the base plate to the base plate, and the coupling elements are connected to the opposing coupling elements, so that the base plate and the tension plate are positively connected to each other. As already explained in the introduction to the previous aspect, in a coupled state, the base plate and the tension plate can be positively connected to each other, thereby enabling the wall element to be firmly mounted or fastened to the base plate. For this purpose, the tension plate is screwed to the wall element and the base plate is attached to the base plate by means of the connecting element.

[0039] In one embodiment of the second aspect, recesses are formed in the wall element on the side to which the drawbar is attached. Each recess directly adjoins a corresponding counter-coupling element, so that when the drawbar and base plate are coupled, the coupling elements project into the respective counter-coupling elements. To allow the coupling elements, which are designed, for example, as connecting hooks, to be inserted into the counter-coupling elements during the coupling process, a recessed area of ​​the wall element is machined.For example, the surface of the wall element that rests against the tension plate can have recesses, such as grooves, milled slots, or slots, to guide the coupling element into the counter-coupling element in accordance with the movement of the linear first component, allowing the coupling element to engage with the counter-coupling element. When the base plate is coupled to the tension plate, the recesses allow the coupling elements to project into their respective counter-coupling elements. This facilitates easy assembly of the base plate to the tension plate.

[0040] Another aspect (third aspect) of the invention relates to a method for attaching a wall element to a base plate by means of at least one fastening device, comprising: Attaching the tension plate to the wall element in a first assembly operation; positioning the wall element directly against the base plate in a second assembly operation following the first; hooking the coupling elements into the respective counter-coupling elements in a third assembly operation following the second assembly operation; and attaching the base plate to the base plate in a fourth assembly operation following the third assembly operation, thereby securing the wall element to the base plate.

[0041] Using the fastening device of the first aspect, a wall element can be attached to the base plate in one assembly operation or assembly procedure.

[0042] For example, the first assembly step can take place at the factory, i.e., at the manufacturer's site. The subsequent second assembly step can then take place on a construction site, such as during the construction of a prefabricated house. Here, the wall element can be positioned or moved directly onto the foundation slab using a crane or other lifting equipment. In a subsequent third assembly step, after the wall element has been positioned on the foundation slab, the base plate can be attached to the tension plate on the wall element, allowing the coupling elements to engage with the corresponding coupling elements and thus connecting the base plate to the tension plate.Once the base plate is coupled to the tension plate, the base plate can be attached to the base plate, particularly using the connecting element. This pulls the wall element towards the base plate and thus secures it. In other words, after the two-part assembly of the tension plate and the base plate, a connecting angle can then be created or realized externally.

[0043] For example, after the base plate has been attached to the base plate, the wall element can be detached from the crane or lifting device, since the wall element is firmly or stably attached to the base plate by means of the fastening device.

[0044] In one embodiment of the third aspect, the tension plate is screwed to the wall element and the base plate is screwed to the base element. The tension plate can be attached to the wall element during the first assembly step, i.e., in a pre-assembly step. After the base plate has been coupled to the tension plate, it can be screwed to the base plate.

[0045] Other fasteners besides screw connections can also be used.

[0046] The invention also includes further developments of the arrangement and method according to the invention, which have features already described in connection with the further developments of the fastening device according to the invention. For this reason, the corresponding further developments of the arrangement and method according to the invention are not described again here.

[0047] The invention also includes combinations of the features of the described embodiments.

[0048] The following describes exemplary embodiments of the invention. This is illustrated by: Fig. 1 a schematic representation of a fastening device for attaching a wall element to a base plate; Fig. 2 a further schematic, in particular lateral, representation of the fastening device made of Fig. 1 Fig. 3 shows a further embodiment of the fastening device from the previous figures, wherein a base plate of the fastening device is coupled to a tension plate of the fastening device; Fig. 4 shows a schematic arrangement of a wall element and a base plate, wherein these are fastened to each other with at least one fastening device according to the previous figures; Fig. 5 shows a further schematic example relating to the arrangement from Fig. 4 ; and Fig. 6 a further schematic arrangement starting from the Fig. 4 .

[0049] The embodiments described below are preferred embodiments of the invention. In these embodiments, the described components each represent individual features of the invention that can be considered independently of one another. Each of these features further develops the invention independently and can therefore be considered part of the invention individually or in a combination other than that shown. Furthermore, the described embodiments can also be supplemented by other features of the invention already described.

[0050] In the figures, functionally identical elements are each provided with the same reference symbols.

[0051] The Fig. 1 Figure 1 shows a schematic representation of a fastening device 1 according to the invention for fastening or mounting a wall element 2 (see Figure 1). Fig. 4 ) on a base plate 3 (see Fig. 4 With the aid of fastening device 1, components such as wooden parts or prefabricated house elements can be fastened together in the simplest way. Therefore, fastening device 1 can be used in construction, for example, in the construction of a house or prefabricated house. Further applications in construction or in connecting or fastening building elements together are also conceivable.

[0052] The fastening device 1 according to the invention finds a special application in wooden structures.

[0053] The fastening device 1 can be designed in two parts. For this purpose, the fastening device 1 can consist of two separate units or components. Firstly, the fastening device 1 has a tension plate 4 and a base plate 5. These two units 4, 5, or these two plates 4, 5, can be physically separate from each other.

[0054] The tension plate 4 can be provided to be attached to the wall element 2, for example a prefabricated house wall of a prefabricated house.

[0055] The base plate 5, in turn, can be attached or arranged on the base plate 3.

[0056] The base plate 3 can, in turn, be a horizontal floor or a horizontal floor surface or a horizontal foundation slab of a prefabricated house or a timber-framed structure. Accordingly, the wall element 2 and / or the base plate 3 can at least partially consist of wood as a material. Other building materials used in the construction of prefabricated houses or timber-framed structures are also conceivable or can be incorporated.

[0057] The two-part fastening device 1 can be configured as a positively connected fastening bracket or angle connector by means of a hook-in function or a coupling mechanism. For this purpose, the base plate 5 can be coupled to the tension plate 4. This creates a positively locked and releasable connection between the base plate 5 and the tension plate 4. This positively locked connection or coupling allows the two separate parts 4 and 5 to be combined into a fastening bracket. This is particularly advantageous in the assembly or construction of a prefabricated house, as these are assembled from several elements. This results in simpler assembly, since at least one of the two units 4 and 5 can be pre-assembled.For example, during the production of wall element 2, the tension plate 4 can be attached to the wall element 2 as a prefabrication step and transported to the construction site, where it can be attached to the base plate 5 by means of a coupling. This results in a simpler assembly of the wall element 2 to the base plate 3 and, more generally, of components during prefabricated house assembly.

[0058] If the base plate 5 is positively connected or coupled to the tension plate 4, a fixed connection of the wall element 2 to the base plate 3 can be achieved. This can be described as arrangement 6 (see figure). Fig. 4 The arrangement 6 can in turn comprise several wall elements, ceiling elements, or side wall elements attached to the base plate 3. For example, the arrangement 6 can represent a floor, such as a ground floor, of a prefabricated house.

[0059] To enable the tension plate 4 to be attached to the wall element 2 during pre-assembly without protruding or extending beyond the wall element 2, thus hindering its transport and handling, the tension plate 4 is designed to be completely flat, i.e., planar. In other words, the tension plate 4 is designed as a flat, metallic plate. This allows the tension plate 4 to be mounted, particularly by screwing, to the wall element 2, and the flat design prevents any protrusions, metal pins, or other obstructions from extending outwards. To facilitate fastening the tension plate 4 to the wall element 2, particularly by screwing, the tension plate 4 may have several recesses 7. These recesses 7 may be pre-drilled holes or pilot holes in the tension plate 4.These can be arranged arbitrarily on or in the tension plate 4. In particular, an evenly distributed arrangement is possible, since, depending on the design of the wall element 2 and the subsequent assembly process, there are various possibilities for attaching or screwing the tension plate 4 to the wall element 2. This simplifies assembly for workers, especially tradespeople. Specifically, screw elements, i.e., screws, or other fasteners can be used to attach the tension plate 4 to the wall element 2.

[0060] The base plate 5, for example, can be attached to the base plate 3, particularly after the base plate 5 has been coupled to the drawbar 4. A connecting element 8 can be provided for this purpose. The connecting element 8 can be, for example, a borehole, hole, recess, or opening within a base plate 9 of the base plate 5. The base plate 5 can be attached to the base plate 3, in particular by screwing, using the connecting element 8. For this purpose, a screw element or a bolt element can be inserted through the connecting element 8, which may be designed as a borehole, and screwed or attached to the base plate 3 accordingly. Further connecting elements, such as boreholes within the base plate 9, can also be provided for this purpose.

[0061] As already mentioned, the positive locking connection of the drawbar 4 to the base plate 5 is achieved through a coupling or coupling process. For this purpose, the base plate 5 has several coupling elements or connecting elements.

[0062] In the Fig. 1 In the illustrated example, the base plate 5 has four coupling elements 10. The tension plate 4 can, in turn, have corresponding counter-coupling elements 11 for the coupling elements 10. Each of the coupling elements 10 can be coupled to a respective counter-coupling element, thereby enabling a positive-locking connection between the tension plate 4 and the base plate 5.

[0063] The coupling elements 10 can be used as connecting hooks or hook elements, as in the Fig. 1 and Fig. 2 is depicted as being trained.

[0064] The counter-coupling elements 11 can, in turn, be designed as receiving areas or passages. During a coupling process between the base plate 5 and the tension plate 4, the hook-shaped coupling elements 10 can be inserted, pushed in, or moved through the counter-coupling elements 11, which are designed as receiving areas, in particular along a movement with a linear first component 12, i.e., parallel to the x-axis. Subsequently, a movement with a linear second component 13 (see Figure 12) can be performed. Fig. 2 ), which is preferably designed perpendicular to the linear first component 12, i.e. parallel to the z-axis, each of the coupling elements 10 is coupled to a respective counter-coupling element 11.

[0065] Components 12 and 13 can be referred to as motion components.

[0066] In other words, the coupling elements 10, designed as hooks, can engage with, or be engaged by, the counter-coupling elements 11, thus realizing a hooking function. They are initially guided horizontally through the counter-coupling elements 11, which are designed as receiving areas, according to the linear first component 12, and then moved according to the linear second component 13. The linear second component 13 is directed specifically towards the base plate 3, so that an engagement occurs, thereby positively connecting the base plate 5 to the tension plate 4. A positive connection can be achieved in five spatial directions. Specifically, in the coupled state, the coupling elements 10 can only be moved upwards, i.e., in the positive Z-direction, to allow decoupling.The base plate 5 can then be attached to the base plate 3 by means of the connecting element 8 in the direction of the linear second components 13, in particular by screwing it on.

[0067] Instead of hook connections, it would also be conceivable that the coupling elements 10 could be designed as snap-fit ​​or locking elements. Conversely, the counter-coupling elements 11 could be designed accordingly.

[0068] In order to carry out an efficient coupling process, the negative feedback elements 11 can be arranged analogously to the coupling elements 10.

[0069] For stability and thus for attaching the wall element 2 to the base plate 3, the base plate 5 has, in addition to the base plate 9, two base plate wall sides 14, 15. As shown in the Fig. 1 As can be seen, the bottom plate wall sides 14, 15, or walls or outer edges, are arranged opposite each other. In particular, the bottom plate wall sides 14, 15 are arranged on opposite outer sides of the bottom plate 9. When the bottom plate 5 is connected or coupled to the tension plate 4 as intended, the two bottom plate wall sides 14, 15 can be configured perpendicular to the tension plate 4. This is the case, for example, in the Fig. 3 to be recognized. The base plate 5 can have a fastening side 16. When the base plate 5 is connected or coupled to the tension plate 4 as intended, the fastening side 16 is directed towards the tension plate 4 or rests against the tension plate 4, as is particularly evident in the Fig. 3 can be seen.

[0070] For example, the two sides of the base plate 14, 15 can be produced by bending. Thus, the base plate 5 is designed as a single piece.

[0071] The base plate 5 can be designed such that the base plate wall sides 14, 15 have end regions 17, 18. These end regions 17, 18 extend on the fastening side 16 and thus towards the tension plate 4 or the wall element 2.

[0072] The coupling elements 10 can each be attached to the end regions 17, 18, as shown in the Fig. 1 As can be seen, the coupling elements 10 are arranged or attached. Thus, on the attachment side 16, the coupling elements 10 are arranged for engaging the counter-coupling elements 11. The coupling elements 10, which can be designed in particular as connecting hooks, are shaped such that they are angled towards the base plate 9 and thus towards the base plate 3, i.e., downwards. This allows the elements 10 and 11 to hook in and thus enable the hooking functionality. The connecting hooks can, in particular, be right-angled and have the hook opening facing downwards, i.e., in linear motion 13.

[0073] As in the present version in the Fig. 1 As shown, two connecting hooks, i.e., coupling elements 10, can be arranged one above the other at each end section 17, 18. Depending on the application, several connecting hooks can be arranged one above the other. The counter-coupling elements 11 are arranged analogously at a distance from each other. The distance between two coupling elements 10 arranged one above the other is essentially the same as the distance between the opposing counter-coupling elements 11. This allows the bottom plate 5 to be coupled to the drawbar 4 by inserting the coupling elements, designed as connecting hooks, into the counter-coupling elements 11 and then hooking them in.

[0074] For improved stability and, in particular, for improved force transmission and distribution, the base plate wall sides 14, 15 can be ramped, as shown in the Fig. 1 and especially in the Fig. 2 as can be seen, it can be designed. The respective height of the base plate wall sides 14, 15 can increase towards the fastening side 16. For example, in an area opposite the fastening side 16, the height 19 of the base plate wall sides 14, 15 is lower than the height 20 in the area of ​​the fastening side 16, as is the case, for example, in the Fig. 2 can be seen.

[0075] In particular, the ramp-shaped base plate wall sides 14, 15 rise in the direction of movement 12.

[0076] During the assembly process of the wall element 2 on the base plate 3, the tension plate 4 can be attached to the wall element 2 in a first assembly step, i.e., in a pre-assembly step. The positioning of the tension plate 4 takes into account the arrangement 6 and, in particular, the respective conditions regarding the positioning between the wall element 2 and the base plate 3 and regarding the assembly space for coupling the base plate 5 with the tension plate 4.

[0077] Subsequently, in a second assembly step, the wall element 2 can be positioned directly against the base plate 3. This can be done, for example, using a crane. The base plate 5 can then be attached to or coupled to the draw plate 4 by engaging the coupling elements 10 with the counter-coupling elements 11 and forming a hook connection. For this purpose, the base plate 5 is first moved in the direction of movement 12 so that the coupling elements 10 are guided through the counter-coupling elements 11. This continues, for example, until a respective lug or hook lug 22, or the angled end part of the coupling element 10, has been partially, or in particular completely, guided through the coupling element 11 and emerges accordingly from the rear side 23 (see figure). Fig. 2 ) of the drawbar 4. Subsequently, vertical linear movements 13 are performed in the direction of movement 12, as in this embodiment in the direction of the base plate 3, so that the coupling elements 10 engage with the counter-coupling elements 11. This couples the elements 4 and 5 to each other, and in particular, the base plate 5 lies flat against the base plate 3. In a subsequent assembly step, the base plate 5 is fastened to the base plate 3 via the connecting element 8 by means of a screw connection.

[0078] In the coupled state of elements 4 and 5, the fastening device 1 has an L-shape, so that in this state, i.e., in the coupled state, the fastening device 1 can be referred to as a mounting bracket. This is, for example, in the Fig. 3 to recognize.

[0079] The movement with the linear second component 13 can, for example, be parallel to the wall element 2 and, in particular, in the negative z-direction. The movement with the linear first component 12, in turn, can be perpendicular to the wall element 2 and, in particular, in the negative x-direction.

[0080] Furthermore, it is conceivable that the arrangements concerning the base plate 5 and the tension plate 4, and the corresponding coupling elements 10 and the counter-coupling elements 11, are configured in reverse. In other words, the tension plate 4 can be attached to the base plate 3 and the base plate 5 to the wall element 2. Accordingly, the coupling elements 10 and counter-coupling elements 11 can be reversed. In this case, the coupling elements 10, designed, for example, as connecting hooks 10, would not be angled towards the base plate 3, but rather angled upwards in the opposite direction to the base plate 3. The coupling would also be reversed in this case.

[0081] In the Fig. 2 Figure 1 shows another schematic representation of the fastening device 1. This shows a side view of the tension plate 4 and a separate base plate 5 arranged at a distance from it.

[0082] As can be seen here, for example, the floor plate wall sides 14, 15 can each have a short, in particular straight, section 24, 25 adjacent to area 12. These sections 24, 25 can have a length 26 extending along the x-axis and constitute 10 percent, in particular 5 percent. After this section 24, as already mentioned at the beginning, the floor plate wall sides 14, 15 can rise in a ramp-like manner.

[0083] In the Fig. 3 A further schematic representation of the fastening device 1 is shown. In this representation, or embodiment, the base plate 5 and the tension plate 4 are coupled or connected, forming a mounting bracket. Here, elements 4 and 5 are positively locked yet detachably connected. As can be seen, the base plate 5 can be described as the shoe or foot of the fastening device 1, since it can be attached to the base plate 3.

[0084] For example, the fastening device 1, when coupled with the drawbar 4 and the base plate 5, can have a height h (viewed in the z-direction) between 10 and 50 cm. The width b (viewed in the y-direction) of the fastening device 1 can, for example, be between 5 and 30 cm. The length I (viewed in the x-direction) of the fastening device 1 can, for example, be between 5 and 30 cm. The wall thickness of the drawbar 4 and the base plate 9 can, for example, be between 1 and 5 cm. The aforementioned exemplary dimensions are not exhaustive and are intended to give the reader a general overview of possible dimensions of the fastening device 1. The specified value ranges may be scaled differently and may have tolerances of 5%, particularly 10%.

[0085] In the following figures Fig. 4 bis 6 Schematic sectional views of the arrangement 6, and thus of the wall element 2 and base plate 3 attached to one another, are shown. In the coupled state of the base plate 5 with the tension plate 4, these two plates are preferably perpendicular to each other. Accordingly, the wall element 2 can preferably be attached perpendicularly to the base plate 3.

[0086] In the Fig. 4 In one embodiment of the wall element 2, it is positioned resting on the base plate 3 and is fastened by means of the fastening device 1.

[0087] In order to implement a hook-in function or mechanism for coupling the coupling element 10 with the counter-coupling element 11, and to enable the coupling element 10 to be moved or guided through the counter-coupling element 11 after the draw plate 4 has already been pre-assembled on the wall element 2, recesses can be formed behind the draw plate 4, i.e., on the rear side 23, which rests against the surface of the wall element 2, in that area of ​​the wall element 2. These recesses 27 can, for example, be grooves, milled edges, elongated openings, or other indentations. They are formed in the wall element 2 such that, after the coupling element 10, i.e., the hook, has passed through the counter-coupling element 11, the lug 22 has space in this recess 27 to then engage the coupling element 10 with the counter-coupling element 11 by movement with the linear second component 13.The recesses are arranged on side 28, which extends to the fastening device 1, such that in the coupled state of tension plate 4 and base plate 5 the coupling elements 10 project into the respective counter-coupling elements 11.

[0088] In the Fig. 5 is it like in the Fig. 4 The arrangement described in Figure 6 between wall element 2, base plate 3 and fastening device 1 is shown in a different embodiment. Here, the wall element 2 can be positioned next to the base plate 3 for fastening.

[0089] In the Fig. 6 Another possible embodiment of arrangement 6 is shown. Here, the wall element 2 can, for example, be an interior wall of the prefabricated house, such that the wall element 2 is positioned within the longitudinal extent 29 of the base plate 3. In this case, at least one fastening device 1 can be provided on both side 28 and the opposite side 30 of the wall element 2.

[0090] In particular, depending on the length of the wall element 2 viewed in the y-axis, several fastening devices 1 may be provided in order to securely or stably fasten the wall element 2.

[0091] The embodiments of the fastening device 1 shown in the preceding figures are not exhaustive, but rather provide an insight into how such a fastening device 1 can be used, particularly in construction. The fastening device 1, which can be described in particular as a two-part fastening bracket, can be used for a wide variety of applications and especially in various situations where different components need to be joined together.

[0092] In particular, the explanations show how a wall element can be attached to a base plate or how wooden components can be attached to each other in the simplest way. BEZUGSZEICHENLISTE:
