Description

[0001] connector

[0002] The invention relates to a connector for detachably connecting two wall elements according to the preamble of patent claim 1.

[0003] It is common practice to connect wall elements, especially wall elements for timber frame construction or timber panel construction, using connectors. This is usually done using angle connectors.

[0004] In a timber frame construction, the individual wall elements have a surrounding frame and are independent components. A timber framework consisting of vertical and horizontal rods provides vertical load-bearing capacity, as well as horizontal bracing through panel-shaped wall materials, embedded struts, or diagonally applied boards. The individual wall elements can be prefabricated for a building, so that they simply need to be connected together at the building's construction site. The use of prefabricated wall and ceiling elements for a timber frame construction is often also referred to as timber panel construction.

[0005] The disadvantage of using conventional connectors to connect wall elements, especially for timber frame or timber panel construction, is that they protrude beyond the wall element after being attached. This limits the ability to prefabricate the wall elements to a limited extent, which is why conventional wall elements are not usually fitted with connectors after production. Instead, the wall elements are attached using the connectors at the construction site.

[0006] Furthermore, previously known connectors have the disadvantage that after two wall elements have been connected, it is often no longer possible to check whether the two wall elements have been connected correctly or in accordance with the manufacturer's specifications.

[0007] The object of the invention is therefore to provide a connector of the type mentioned at the outset with which the disadvantages mentioned can be avoided and with which two wall elements can be connected to one another and also separated again easily and quickly.

[0008] According to the invention, this is achieved by the features of patent claim 1.

[0009] This has the advantage that two wall elements can be connected to one another quickly and easily. To connect two wall elements to one another, all that is required is that the first connecting part be attached to a first wall element and the second connecting part be attached to a second wall element, the two wall elements be arranged such that the two connecting parts are arranged adjacent to one another, and the at least one locking part is applied to the spring. This means that the building can be erected on site much more quickly than when using currently known connectors. The connector according to the invention can be used at a variety of different node connections, such as longitudinal and T-joints, where different connectors would normally be required.This allows the prefabrication of wall elements to be improved, whereby fastening locations for the connecting parts can be specified at predeterminable positions on the wall elements, or connecting parts according to the invention can be fastened to the wall elements during production, whereby the wall elements only need to be connected to one another at the construction site using the at least one locking part. Furthermore, the connection between the two wall elements can also be quickly released again by simply removing, in particular pulling off, the at least one locking part from the spring. In summary, this creates a multifunctional connector which has a high load-bearing capacity in different loading directions, is simple and versatile in use, and ensures traceable disassembly.

[0010] The invention further relates to a building according to claim 10.

[0011] The invention further relates to a method for detachably connecting two wall elements by means of the connector according to the invention according to claim 12. The invention therefore has the further object of specifying a method of the type mentioned at the outset, with which the disadvantages mentioned can be avoided, with which two wall elements can be connected to each other and also separated again easily and quickly.

[0012] According to the invention, this is achieved by the features of patent claim 12.

[0013] The advantages of the process correspond to the advantages of the connector mentioned above.

[0014] The subclaims relate to further advantageous embodiments of the invention.

[0015] The invention will be described in more detail with reference to the accompanying drawings, in which only preferred embodiments are shown by way of example. In the drawings:

[0026] 1 to 11 show at least parts of a connector 1 for detachably connecting two wall elements 2, wherein the connector 1 comprises a first connecting part 3 with a first elevation 4, a second connecting part 5 with a second elevation 6 and at least one closure part 7, wherein the closure part 7 has a groove 8 for a tongue and groove type connection of the closure part 7 with the first and second connecting parts 3, 5, wherein the groove 8 is at least partially undercut and has an open edge on at least one end face 9 of the closure part 7, wherein the first elevation 4 and the second elevation 6 - when the first and second connecting parts 3, 5 are in abutting relationship - form with one another a tongue 10 for connection to the groove 8 of the at least one closure part 7, wherein the tongue 10 is formed at least partially opposite to the groove 8 of the at least one closure part 7.

[0027] Furthermore, a building comprising at least two wall elements 2 and the connector 1 according to the invention is provided, wherein the first connecting part 3 is fastened to a first wall element 2 and the second connecting part 5 is fastened to a second wall element 2, and wherein the groove 8 of the at least one closure part 7 at least partially engages around the formed tongue 10 of the first and second connecting parts 3, 5 for connecting the first wall element 2 and the second wall element 2 to one another in a form-fitting manner.

[0028] Furthermore, a method for detachably connecting two wall elements 2 by means of the connector 1 according to the invention is provided, wherein the first connecting part 3 is fastened to a first wall element 2, wherein the second connecting part 5 is fastened to a second wall element 2, wherein the first wall element 2 is arranged facing the second wall element 2 in such a way that the tongue 10 is formed by the first elevation 4 and the second elevation 6, and wherein the groove 8 of the at least one closure part 7 is at least partially positively connected to the tongue 10. This results in the advantage that two wall elements 2 can be connected to one another quickly and easily.As a result, to connect two wall elements 2 to one another, only the first connecting part 3 needs to be attached to a first wall element and the second connecting part 5 to a second wall element, the two wall elements need to be arranged such that the two connecting parts 3, 5 are arranged adjacent to one another, and the at least one locking part 7 is applied to the spring 10. This allows the building to be erected at the construction site much more quickly than when using currently known connectors. The connector 1 according to the invention can be used at a variety of different node connections, such as longitudinal and T-joints, where different connectors would normally be required.This allows the prefabrication of wall elements 2 to be improved, wherein fastening locations of the connecting parts 3, 5 can be specified at predeterminable positions of the wall elements 2 or connecting parts 3, 5 according to the invention can be fastened to the wall elements 2 during production, whereby the wall elements 2 only need to be connected to one another at the erection site with the at least one locking part 7. Furthermore, the connection between the two wall elements 2 can also be quickly released again by merely removing, in particular pulling off, the at least one locking part 7 from the spring 10. In summary, this makes it possible to create a multifunctional connector 1 which has a high load-bearing capacity in different loading directions, is simple and versatile in use and ensures traceable disassembly.

[0029] The connector 1 is suitable for connecting two wall elements 2. The connector 1 has the material-specific properties required for connecting the two wall elements 2.

[0030] Connector 1 is preferably a wood connector. A wood connector is suitable for connecting two wooden components.

[0031] The wall elements 2 are preferably wall elements 2 of a building, in particular a timber structure, a timber frame structure, and / or a timber panel structure. The wall element 2 is preferably a wall-like component, in particular a panel or a wooden panel, and / or a rod-shaped component, in particular a post or a wooden post.

[0032] Preferably, the wall element 2 is a prefabricated part of a building, in particular a prefabricated house. In particular, the wall element 2 is at least part of a wall plate of the building. A wall plate is a well-known term from structural engineering and describes a wall that, as a flat load-bearing structure, has a plate effect, i.e., is loaded by forces lying in its plane.

[0033] Preferably, the connector 1 is also suitable for connecting components for a building ceiling, in particular for connecting ceiling panels.

[0034] The building is preferably a prefabricated house.

[0035] The building is preferably a timber frame structure. Timber frame construction is also known as timber frame construction, timber rib construction, or timber frame construction.

[0036] The connector 1 comprises a first connecting part 3 with a first elevation 4 and a second connecting part 5 with a second elevation 6. Various views of a preferred embodiment of the first and / or second connecting part 3, 5 are shown by way of example. Fig. 1 shows an axonometric view, Fig. 2 a top view, Fig. 2 a right-hand side view, Fig. 4 a front view, and Fig. 5 a bottom view of the connecting part 3, 5.

[0037] Preferably, the first and / or the second connecting part 3, 5 is made of metal, in particular comprising iron and / or aluminum.

[0038] Preferably, the first and / or the second connecting part 3, 5 can be formed from a polymer, in particular from plastic.

[0039] It can be provided particularly preferably that the first and / or the second connecting part 3, 5 has a substantially plate-shaped base body 11 and that the first and / or the second elevation 4, 6 extends from the plate-shaped base body 11. This can be seen by way of example in Fig. 1, 3 and 4. By means of the substantially plate-shaped base body 11, a stable fastening of the first and / or second connecting part 3, 5 to a wall element 2 with good contact can be achieved. By means of the substantially plate-shaped design, the fastening can be carried out for example by means of an adhesive, which adhesive is applied to the underside of the plate-shaped base body 11. The underside of the plate-shaped base body 11 can be seen by way of example in Fig. 5.Due to the essentially plate-shaped base body 11, the first and / or the second connecting part 3, 5 can also be screwed particularly well to a wall element 2, since sufficient space is created for fastening openings 12.

[0040] Preferably, the first and / or the second elevation 4, 6 extends away from the substantially plate-shaped base body 11.

[0041] Preferably, the first and / or second connecting part 3, 5 is formed as a single piece. It can preferably be provided that the first and / or second connecting part 3, 5 is milled from a metal block or that the first and / or second connecting part 3, 5 is formed as an injection-molded part.

[0042] According to the invention, the first elevation 4 of the first connecting part 3 and the second elevation 6 of the second connecting part 5 form a spring 10 when in contact with one another. This can be seen by way of example in Fig. 10. As can be seen, the first elevation 4 forms a first part of the spring 10 and the second elevation 6 forms a second part of the spring 10. The formed spring 10 is designed to connect to the groove 8 of the at least one closure part 7, wherein the spring 10 is designed, at least in regions, to be opposite to the groove 8 of the at least one closure part 7. This can be seen by way of example in Fig. 3 and Fig. 9, wherein Fig. 3 is a side view from the right of the connecting part 3, 5 shown in Fig. 1 and Fig. 9 shows the closure part 7 shown in Fig. 7 in front view. Fig. 9 shows the end face 9 of the closure part 7, to which end face 9 the reference number 9 points.7 and 9, the groove 8 is open at the edge on the front side 9.

[0043] As shown by way of example in Fig. 3, a raised cross-section that is substantially perpendicular to the longitudinal direction 15 of the first and / or second connecting part 3, 5 can vary along the longitudinal direction 15. Particularly preferably, it can be provided that a raised cross-section of the first and / or second raised portion 4, 6 that is substantially perpendicular to the longitudinal direction 15 of the first and / or second connecting part 3, 5 widens along the longitudinal direction 15 up to the center 16 of the first and / or second connecting part 3, 5. This makes it particularly easy to form a non-positive and positive connection of the at least one closure part 7 to the first and second connecting part 3, 5, and to facilitate the connection of the at least one closure part 7 to the tongue 10. This makes it particularly easy to push the groove 8 of the at least one closure part 7 onto the tongue 10 with the open-edged end face 9.The longitudinal direction 15 of the first and / or second connecting part 3, 5 is shown as an example in Fig. 2.

[0044] Preferably, an axis of symmetry can be arranged in the center 16 of the first and / or second connecting part 3, 5, wherein the first and / or second elevation 4, 6 extends symmetrically from the axis of symmetry toward two ends of the first and / or second connecting part 3, 5. The center 16 of the first and / or second connecting part 3, 5 is shown by way of example in Fig. 2.

[0045] The connector 1 further comprises at least one closure part 7.

[0046] Preferably, the at least one closure part 7 is made of metal, in particular comprising iron and / or aluminum.

[0047] Preferably, the at least one closure part 7 can be formed from a polymer, in particular from plastic.

[0048] The at least one closure part 7 comprises a groove 8 for a tongue and groove connection of the at least one closure part 7 with the first and second connecting parts 3, 5. For this purpose, the tongue 10 is formed at least partially opposite to the groove 8 of the at least one closure part 7.

[0049] The groove 8 of the at least one closure part 7 is at least partially undercut. Undercut in the sense of the invention means that the at least one closure part 7 cannot be lifted off the spring 10 after being applied to the first and second connecting parts 3, 5.

[0050] Preferably, the at least one closure part 7 can be pushed onto the spring 10 and, after being pushed on, cannot be lifted off the spring 10 without the application of considerable force. According to the invention, the at least one closure part 7 is positively held against lifting by the undercut in a connected state of the connector 1. The connected state of the connector 1 is the state in which the first connecting part 3 rests against the second connecting part 5, thereby forming the spring 10, and the groove 8 of the at least one closure part 7 is connected to the spring 10.

[0051] Preferably, the groove 8 can be dovetail-shaped.

[0052] Preferably, the undercut can also be formed by milling into a groove side wall, wherein - in a connected state of the connector 1 - an opposite bead of the first and the second elevation 4, 6 engages in a milled groove side wall area.

[0053] Preferably, the at least one closure part 7 for connecting to the first and second connecting parts 3, 5 is pushed onto the formed spring 10 of the first and second connecting parts 3, 5.

[0054] Preferably, the at least one closure part 7 is open-edged on at least one end face 9 of the closure part 7. The end face 9, on which the at least one closure part 7 is open-edged, is shown by way of example in Fig. 7 and in the longitudinal section in Fig. 8.

[0055] Preferably, the at least one closure part 7 is formed in one piece. It can preferably be provided that the at least one closure part 7 is milled from a metal block or that the at least one closure part 7 is formed as an injection-molded part.

[0056] Particularly preferably, it can be provided that the first and / or second connecting part 3, 5 has fastening openings 12 for fastening to a wall element 2. Preferably, the first and / or second connecting part 3, 5 is fastened to a wall element 2 by means of fastening means, such as screws and / or nails, and the fastening openings 12. This allows for simple and secure fastening to a wall element 2 using conventional fastening means, since only the fastening means needs to be inserted into the wall element 2 through the fastening opening 12.

[0057] Preferably, the first and / or the second connecting part 3, 5 can have at least two, in particular at least four, preferably at least eight, fastening openings 12.

[0058] Preferably, at least two, in particular four, fastening openings 12 can be formed at an angle to the plate normal. The plate normal is the normal vector to the surface of the base body 11.

[0059] Particularly preferably, it can be provided that the first and / or the second connecting part 3, 5 has a securing device 13 for securing the at least one closure part 7 in a state in which it engages around the spring 10. The state in which it engages around the spring 10 is preferably the state in which the at least one closure part 7 is pushed onto the spring 10. As a result, with a vertical arrangement of the closure part 7, with the end face 9 of the groove 8 with the open-edged opening facing upwards, a long-term fixation of the closure part 7 in the state in which it engages around the spring 10 can be achieved. As a result, a loosening of the at least one closure part 7 due to shocks and vibrations can be effectively prevented.

[0060] Preferably, the securing device 13 can be an opening into which a fastening means, such as a screw, a pin, or a nail, can be inserted to secure the at least one closure part 7 in the state encompassing the spring 10. Preferably, the fastening means is inserted through the opening into a wall element 2 to such an extent that it projects beyond the opening, i.e., does not end flush with the plate-shaped base body 11, and thereby mechanically prevents the closure part 7 from detaching from the spring 10.

[0061] Preferably, the securing device 13 may comprise a securing spring, which securing spring fixes the at least one closure part 7 in the state encompassing the spring 10.

[0062] Particularly preferably, the first connecting part 3 and the second connecting part 5 are designed identically. This results in particular in advantages in the production of the connector 1, since only one type of connecting part 3, 5 needs to be formed, as well as in the planning of connection points on prefabricated wall components.

[0063] Particularly preferably, it can be provided that the first connecting part 3 and the second connecting part 5 each have a flat contact surface 14, and that the two contact surfaces 14 abut one another when the first and second connecting parts 3, 5 are connected. It is provided that the contact surface 14 is a substantially flat surface without tooth-like elevations and depressions. This allows a flush connection of the connecting part 3, 5 to the wall element 2, which can facilitate the prefabrication of the wall element 2 and handling during connection.

[0064] Particularly preferably, it can be provided that the first elevation 4 and / or the second elevation 6—when the first and second connecting parts 3, 5 are in contact with one another—form a continuous spring surface 18. This makes it particularly easy to form a stable spring 10, since the first elevation 4 and the second elevation 6—when in contact with one another—support one another. The spring surface 18 is shown as an example in Fig. 10.

[0065] It can preferably be provided that a visible surface of the first and second connecting parts 3, 5 - in the connected state - is larger than a visible surface of the at least one closure part 7. The visible surfaces are the surfaces which can be seen, for example, in Fig. 11. The visible surface of the first and second connecting parts 3, 5 results from the surface of the first and second connecting parts 3, 5, as can be seen in Fig. 10, less the surface of the at least one closure part 7. It can preferably be provided that the fastening openings 12 are accessible in the connected state. It can preferably be provided that the fastening openings 12 are accessible after the at least one closure part 7 has been connected to the spring 10. This allows the assembly andthe fastening of the first and / or the second connecting part 3, 5 to the wall element 2 can be checked particularly easily without the connection of the two wall elements 2 having to be released by means of the connector 1.

[0066] Preferably, a length 19 of the first and / or second connecting part 3, 5 can be at least twice, in particular at least three times, preferably at least four times, a width 20 of the first and / or second connecting part 3, 5. The length 19 of the first and / or second connecting part 3, 5 is to be measured along the longitudinal direction 15. The width 20 is to be measured orthogonally to the longitudinal direction 15. The length 19 and the length 20 are shown by way of example in Fig. 2.

[0067] Preferably, the ratio of the length 19 of the first and / or second connecting part 3, 5 to the width 20 of the first and / or second connecting part 3, 5 may be substantially 4:1.

[0068] Preferably, the length 19 of the first and / or second connecting part 3, 5 can be at least four times, in particular at least eight times, preferably at least ten times, a height 21 of the first and / or second connecting part 3, 5.

As a result, the connection can be made even stronger than with just one closure part 7. Fig. 11 shows, by way of example, the connection of two wall elements 2 by means of the connector 1 according to the invention, wherein in the connector 1 two closure parts 7 are arranged on the tongue 10.

[0076] Preferably, it can be provided that the two closure parts 7 are designed identically.
