Description

[Technical Field]

[0001] The present invention relates to a profile for dry construction, comprising a first peripheral edge and a second peripheral edge which are connected to each other via a web. [Background technology]

[0002] Such a profile is known, for example, from DE 10216675 (B4). The profile forms a support structure and serves to receive a flat structural panel, such as a gypsum plasterboard, which is fixedly fastened to the periphery of the profile.

[0003] Therefore, the profiles are usually made of metal materials, which often have good heat conduction properties. When thermal isolation is achieved by walls constructed with profiles, the metal profiles that extend from one side of the wall to the other form thermal bridges through which significant heat transfer can occur.

[0004] In the case of previously known profiles, the separation of the two peripheral edges is provided by a separating gap inside which an elastic material is introduced and which is connected to the peripheral edges by means of an adhesive connection.

[0005] A further problem is that sound is transmitted through the profile and the propagation of sound within the profile is not impeded. Summary of the Invention [Problem to be solved by the invention]

[0006] The object of the present invention is to provide a profile for dry construction, which allows thermal isolation of the two peripheries and which can be manufactured easily and cheaply. [Means for solving the problem]

[0007] This object is achieved by the features of claim 1. The dependent claims point out advantageous embodiments.

[0008] To achieve this, the web panels are formed from web elements that are form-fitted to the first and second peripheral edges. Because the web panels are formed from multiple web elements, thermal isolation of the two edges is already achieved, regardless of the material of the web elements. Due to the form-fitted web elements that are connected to the first and second peripheral edges, the profile is particularly simple and inexpensive to manufacture. It is only necessary to fasten the web elements to both edges. In particular, there is no need to provide additional connecting means or create adhesive connections between the elements.

[0009] Furthermore, advantageously, because the profile comprises multiple portions, sound propagation within the profile is reduced, resulting in improved sound isolation.

[0010] The first and second peripheries can each have fastening sections, with openings introduced into the fastening sections and the web elements fastened into the openings. The fastening sections are preferably formed as strips and arranged relative to one another in a plane. Therefore, multiple openings are introduced into each fastening section. This can be preferably implemented in the form of a hole pattern with regularly spaced circular openings. This allows for flexible placement of the web elements within the two peripheries. For example, the number of web elements can be increased or decreased to form the profile depending on the expected load situation. The openings further improve the sound isolation properties of the profile.

[0011] The web elements preferably have the form of plates, which design allows them to be manufactured simply and inexpensively, since they are formed as flat elements.

[0012] The web element is preferably provided with form-fitting elements, which are connected to the fastening portions of the first and second peripheral edges via the form-fitting elements, and thus engage in the openings of the fastening portions so that the web element is fixedly connected to the fastening portions of the first and second peripheral edges.

[0013] The form-fitting element can comprise a bore or a fastening element, the fastening element being introduced into the bore, such that the web element is disposed on one side of the fastening portion of the peripheral edge, and the fastening element is disposed on the other side of the fastening portion and protrudes through the opening in the peripheral edge into the bore of the web element.

[0014] The fastening element is therefore preferably fastened in the bore of the web plate element by a snap-fit ​​connection. For this purpose, the bore of the web plate element is provided with a cross-sectional extension on the side facing away from the fastening element. The fastening element then has a protrusion, the free end of which is provided with an elastically tiltable conical cross-sectional extension. When pressed into the bore, the cross-sectional extension is deformed and fixedly fastened within the cross-sectional extension. In this way, the fastening element securely fastens the web plate element to the first or second peripheral edge.

[0015] According to an alternative embodiment, each web element can be provided with form-fitting elements in the form of bores and protrusions, each of which is associated with two web elements. In this embodiment, separate fastening elements are omitted. For fastening purposes, the two web elements are preferably arranged back-to-back and receive fastening portions on the first and second peripheral edges. This results in a particularly stable mechanical connection and a particularly stable mechanical profile.

[0016] The bores and protrusions of the form-fitting elements are therefore preferably designed in a matching manner: for joining purposes, the protrusions of one web element engage in the bores of the adjacent other web element, and thus pass through the openings of the peripheral fastening portion.

[0017] The web element can have a first edge portion assigned to a first periphery and a second edge portion assigned to a second periphery, with the bores and protrusions disposed on the first edge and the second edge, respectively. Furthermore, the bores and protrusions are preferably arranged so that the bores and protrusions on the first edge are point-symmetric with respect to the arrangement of the bores and protrusions on the second edge. In this embodiment, a single web element is advantageously sufficient to form the profile. For fastening purposes, the first web element is disposed within the two peripheral openings, and the second web element is fastened to the first web element in a mirror-symmetric, back-to-back manner. Thus, the protrusions of the two web elements each pass through the two peripheral openings. Furthermore, the protrusions of one web element engage within the bores of the other web element. This allows the profile to be produced quickly and inexpensively. Furthermore, only one single forming tool is required to manufacture the web element.

[0018] The web elements are preferably made of a non-metallic material, in particular a synthetic material. Therefore, it is preferable to use a synthetic material that can be injection molded. In this case, it is advantageous that the synthetic material is inexpensive. Furthermore, the synthetic material has favorable thermal properties. The synthetic material has a relatively low thermal conductivity, which influences the thermal isolation of the two edges. The synthetic material also has sound-isolating properties, especially compared to metallic materials.

[0019] In addition to the use of synthetic materials, the use in the form of composite materials, for example, fiber-reinforced synthetic materials, is also specifically contemplated.

[0020] The first and second peripheries are preferably made of a metal material, which allows the processing of the profile or the attachment of the wall elements to the profile using conventional means known in particular from dry construction technology.

[0021] The fastening flange for receiving the drywall panel is formed from a first peripheral edge and a second peripheral edge. The peripheral edge is thus preferably formed so that the flat element can be placed on the peripheral edge, and two adjacent wall elements can also be placed edge-to-edge on the peripheral edge. The wall elements are preferably fastened together by a threaded connection. Drywall screws can be used for this purpose.

[0022] The profile is preferably formed as a C-profile, such profiles being commonly used in dry construction.

[0023] The wall according to the invention comprises a plurality of profiles according to the invention and at least one flat structural panel fixed to the fastening flange of the profile, preferably on both sides of the profile. Since both edges of the profile are thermally separated by separately formed web elements, the wall has good thermal insulation properties.

[0024] In the following, several embodiments of the profiles according to the invention are explained in more detail with the help of figures which show, in each case, schematically: [Brief explanation of the drawings]

[Figure 10] A wall having the profile of FIG. 5. DETAILED DESCRIPTION OF THE INVENTION

[0026] FIG. 1 shows a cross-sectional view and a three-dimensional view of a profile 1 for dry construction. The profile 1 comprises a first peripheral edge 2 and a second peripheral edge 3. Both edges 2, 3 are made of a metal material. The first peripheral edge 2 and the second peripheral edge 3 are connected to each other via a web 4. The web 4 is formed from a number of web elements 5, which are connected to the first peripheral edge 2 and the second peripheral edge 3 in a form-fitting manner. The web elements 5 are made of a synthetic material that can be injection-molded.

[0027] The profile 1 is formed as a C-shaped profile and has fastening flanges 14 for receiving dry elements. The two fastening flanges 14 are arranged parallel to each other. The first peripheral edge 2 and the second peripheral edge 3 each have a fastening portion 6. The fastening portions 6 are formed as strips and both fastening portions 6 are arranged in the same horizontal plane. The two fastening portions 6 are formed from the first peripheral edge 2 and the second peripheral edge 3 and face each other. Openings 7 in the form of circular holes are introduced into the fastening portions 6. The web elements 5 are fastened into the openings 7.

[0028] The web element 5 is formed as a plate and is substantially flat.

[0029] The web element 5 has a first edge 12 assigned to the first periphery 2 and a second edge 13 assigned to the second periphery 3. Form-fitting elements 8 are arranged in the region of both edges 12, 13. The web element 5 is connected to the fastening parts 6 of the first periphery 2 and the second periphery 3 via the form-fitting elements 8.

[0030] In this embodiment, the form-fitting element 8 comprises a bore 9 and a fastening element 10. To form the profile 1, the web element 5 is arranged on one side of the fastening portion 6, and the fastening element 10 is arranged on the other side of the fastening portion 6 and protrudes through the opening 7 into the bore 9 of the web element 5.

[0031] The fastening element 10 is formed as a latching element and preferably has a button-like shape. The fastening element 10 comprises a pin 17 with a central undercut. The bore 9 of the web element 5 has a cross-sectional extension on the side facing away from the fastening portion 6. The pin 17, which is conically shaped at its free end, is deformed when pressed into the bore 9 so that it finally locks in a form-fitting manner into the cross-sectional extension. In this way, the fastening element 10 securely fastens the web element 5 onto the first peripheral edge 2 or the second peripheral edge 3.

[0032] FIG. 2 shows the front or rear face of the web element 5 in detail and in a three-dimensional manner.

[0033] FIG. 3 shows the aforementioned web element 5 in front view, in plan view and in cross section in the plane AA.

[0034] FIG. 4 shows a side view and a cross section in plane BB of the profile 1 according to FIG.

[0035] FIG. 5 shows an alternative embodiment of the profile 1 in cross section and in a three-dimensional view. The profile 1 according to FIG. 5 also comprises a first peripheral edge 2 and a second peripheral edge 3. Both edges 2, 3 are made of a metal material. The first peripheral edge 2 and the second peripheral edge 3 are connected to each other via a web 4. The web 4 is therefore formed from a plurality of web elements 5, which are connected to the first peripheral edge 2 and the second peripheral edge 3 in a form-fitting manner. The web elements 5 are made of a synthetic material that can be injection-molded. The web elements 5 are formed as plates and are substantially flat.

[0036] The profile 1 is formed as a C-shaped profile and has fastening flanges 14 for receiving dry elements. The two fastening flanges 14 are arranged parallel to each other. The first peripheral edge 2 and the second peripheral edge 3 each have a fastening portion 6. The fastening portions 6 are formed as strips and both fastening portions 6 are arranged in the same horizontal plane. The two fastening portions 6 are formed from the first peripheral edge 2 and the second peripheral edge 3 and face each other. Openings 7 in the form of circular holes are introduced into the fastening portions 6. The web elements 5 are fastened to the openings 7.

[0037] In this embodiment, the web elements 5 are fastened to the fastening portions 6 in such a way that in each case two web elements 5 are arranged back to back relative to each other and thus receive the fastening portions 6 of the first peripheral edge 2 and the second peripheral edge 3 between them.

[0038] Each web element 5 comprises form-fitting elements 8 in the form of bores 9 and protrusions 11. The bores 9 and protrusions 11 of the form-fitting elements 8 of the web elements 5 thus fit together. The protrusions 11 can be inserted into the bores 9 in a form-fitting manner and latched within the bores 9. Each web element 5 comprises bores 9 and protrusions 11 on a first edge 12 and a second edge 13. The arrangement of the bores 9 and protrusions 11 on the first edge 12 is therefore point-symmetrical to the arrangement of the bores 9 and protrusions 11 on the second edge 13. In this respect, only a single type of web element 5 is sufficient to form the profile 1. The first web element 5 is fixed in the fastening section 6 by means of the openings 7, and the second web element 5 is fastened to the other web element 5 at an angle of 180°. The two web elements 5 therefore receive the fastening section 6 between them. In this embodiment, the two back sides of the two web elements 5 face each other. Furthermore, the first edge 12 of one web element 5 is assigned to the second edge 13 of the other web element 5.

[0039] FIG. 6 shows the front or rear side of the web element 5 according to FIG. 5 in detail and in a three-dimensional manner.

[0040] FIG. 7 shows the aforementioned web element 5 in a front view and in two cross-sectional views, one in the plane CC and one in the plane EE.

[0041] FIG. 8 shows a side view and a cross section in the plane DD of the profile 1 according to FIG.

[0042] Figure 9 shows a wall 15 comprising a number of profiles 1 according to Figure 1 and a number of flat structural panels 16 fixed onto the fastening flanges 14 of the profiles 1. The structural panels 16 are made, for example, of gypsum plasterboard and are fixed into the fastening flanges 14 of the profiles 1 using fastening means 17, for example in the form of screws.

[0043] Figure 10 shows a wall 15 comprising a number of profiles 1 according to Figure 5 and a number of flat structural panels 16 fixed onto the fastening flanges 14 of the profiles 1. The structural panels 16 are, for example, made of gypsum plasterboard and are fixed into the fastening flanges 14 of the profiles 1 using fastening means 17, for example in the form of screws.
