Description

Profile
The invention relates to a profile for dry construction, comprising a first limb and a second limb which are connected to one another via a web. Such profiles are known e.g. from DE 102 16 675 B4. The profile forms a support structure and serves to receive flat construction panels e.g. gypsum plaster boards. The flat construction panels are fixedly fastened to the limbs of the profile.
The profiles are thus usually formed from metallic material. In this case, it is problematic that metallic materials frequently have good heat-conducting properties. If thermal separation is to be carried out by means of the wall erected using the profiles, the problem is that the metallic profiles, which extend from one side of the wall to the other side of the wall form a heat bridge via which a considerable heat transfer is possible.
In the case of the previously known profile, a separation of the two limbs is effected by a separation gap, into which an elastic material is introduced and is connected to the limbs by an adhesive connection.
A further problem is that sound is transmitted through the profile, wherein the propagation of sound within the profile is not disrupted.
The object of the invention is to provide a profile for dry construction, which makes thermal decoupling of the two limbs possible and can be produced easily and inexpensively. This object is achieved by the features of claim 1. The dependent claims refer to advantageous embodiments.
In order to achieve this object, the web is formed of web elements and the web elements are connected in a form-fitting manner to the first limb and the second limb. Owing to the fact that the web is formed from a plurality of web elements, thermal decoupling of the two limbs is already achieved independently of the selection of the material of the web elements. Due to the fact that the web elements are connected in a form-fitting manner to the first limb and the second limb, the profile is particularly easy and inexpensive to produce. It is merely necessary to fasten the web elements to both limbs. In particular, it is not necessary to provide additional connection means or to produce an adhesive connection between the elements.
Furthermore, it is advantageous that sound propagation within the profile is reduced because the profile comprises multiple parts, and so improved sound decoupling is achieved.
The first limb and the second limb can each comprise a fastening portion, wherein openings are introduced into the fastening portions, wherein the web elements are fastened in the openings. Thus the fastening portions are preferably formed as strips and disposed with respect to each other in a plane. Thus a plurality of openings are introduced into each fastening portion. This can be effected preferably in the form of a pattern of holes with circular openings at regular intervals. This makes possible a flexible arrangement of the web elements in the two limbs. For example, depending on the expected loading situation, the number of web elements can be increased or reduced in order to form the profile. The openings further improve the sound-decoupling properties of the profile.
The web elements preferably have the form of plates. In the case of this design, the web elements are formed as flat elements and can thus be produced easily and inexpensively.
The web elements are preferably provided with form-fitting elements, wherein the web elements are connected via the form-fitting elements to the fastening portions of the first limb and of the second limb. Thus, the form-fitting elements engage into the openings of the fastening portions so that the web elements are fixedly connected to the fastening portions of the first limb and of the second limb.
The form-fitting elements can comprise bores or fastening elements, wherein the fastening elements are introduced into the bores. Thus, the web elements are disposed on one side of the fastening portions of the limbs and the fastening elements are disposed on the other side of the fastening portions and protrude through the openings of the limbs into the bores of the web elements.
Thus, the fastening elements are fastened in the bores of the web elements, preferably by means of a snap-fit connection. For this purpose, the bores of the web elements on the side facing away from the fastening elements are provided with a cross-sectional extension. The fastening elements in turn comprise protrusions, on the free ends of which elastically tiltable conical cross-sectional extensions are disposed. These are deformed when being pressed into the bores and are fixedly braced in the cross-sectional extension. In this way, by means of the fastening element, the web element is fixedly fastened on the first limb or the second limb.
According to an alternative embodiment, each web element can comprise form-fitting elements in the form of bores and protrusions, wherein in each case two web elements are allocated to one another. In this embodiment, the separate fastening elements are omitted. For fastening purposes, two web elements are preferably disposed back-to-back and receive the fastening portions of the first limb and second limb. This results in a mechanically particularly stable connection and a mechanically particularly stable profile.
Thus the bores and protrusions of the form-fitting elements are designed in a preferably congruent manner. For joining purposes, the protrusion of a web element engages into the bore of the adjacent other web element. Thus the protrusions pass through the openings of the fastening portions of the limb.
The web elements can comprise a first edge allocated to the first limb and a second edge allocated to the second limb, wherein a bore and a protrusion are disposed respectively on the first edge and on the second edge. Furthermore, the bore and protrusion are preferably arranged such that the bore and protrusion on the first edge have point symmetry with respect to the arrangement of the bore and protrusion on the second edge. In this embodiment, it is advantageous that a single embodiment of the web element will suffice to form the profile. For fastening purposes, a first web element is disposed in the openings of the two limbs and a second web element is fastened on the first web element in a mirror-symmetrical and back-to- back manner. Thus, the protrusions of the two web elements each pass through the openings of the two limbs. Furthermore, the protrusions of one web element engage into the bores of the other web element. Thus, the profile can be produced quickly and inexpensively. Furthermore, only one single forming tool is required in order to produce the web elements.
The web elements preferably consist of a non-metallic material, in particular synthetic material. Thus a synthetic material which can be injection moulded is preferably used. In this case, it is advantageous that synthetic materials are inexpensive. Furthermore, synthetic materials have advantageous thermal properties. Synthetic materials have a relatively low level of heat conductivity, which effects thermal decoupling of the two limbs. Synthetic materials also have sound-decoupling properties, especially compared to metallic materials.
In addition to the use of synthetic materials, composite materials are also particularly considered, e.g. in the form of fibre-reinforced synthetic material.
The first limb and the second limb are preferably formed from metallic material. This permits in particular the processing of the profiles, or the mounting of wall elements on the profiles, using conventional means known from dry construction technology.
Fastening flanges for receiving dry construction panels are formed from the first limb and from the second limb. Thus the limbs are preferably formed in such a way that flat elements are placed on the limbs, wherein two adjacent wall elements can also be disposed edge-to-edge on the limbs. The wall elements are preferably fastened by means of a screw connection. Drywall screws can be used for this purpose.
The profile is preferably formed as a C-shaped profile. Such profiles are commonly used in dry construction.
A wall in accordance with the invention comprises a plurality of profiles in accordance with the invention and at least one flat construction panel which is fixed on the fastening flanges of the profiles. Flat construction panels are preferably fixed on both sides of the profiles. Owing to both limbs of the profile being thermally decoupled by the separately formed web elements, a wall with good thermal insulation is produced.
In the following, some embodiments of the profile in accordance with the invention will be explained in more detail with the help of the figures. The figures illustrate, in each case schematically:

profile;

Fig. 8 a side view and a cross-sectional view in plane D-D of a profile according to the
second embodiment;
Fig. 9 a wall with a profile according to figure 1 ; Fig. 10 a wall with a profile according to figure 5.
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 limb 2 and a second limb 3. Both limbs 2, 3 consist of metallic material. The first limb 2 and the second limb 3 are connected to one another via a web 4. The web 4 is formed from a plurality of web elements 5, wherein the web elements 5 are connected in a form-fitting manner to the first limb 2 and the second limb 3. The web elements 5 consist of a synthetic material which can be injection moulded.
The profile 1 is formed as a C-shaped profile and comprises fastening flanges 14 to receive dry elements. The two fastening flanges 14 are disposed parallel to one another. The first limb 2 and the second limb 3 each comprise a fastening portion 6. The fastening portion 6 is formed as a strip and both fastening portions 6 are disposed in the same horizontal plane. The two fastening portions 6 are formed from the first limb 2 and the second limb 3 and point towards each other. Openings 7 in the form of circular holes are introduced into the fastening portions 6. The web elements 5 are fastened in the openings 7.
The web elements 5 are formed as plates and are substantially flat. The web elements 5 comprise a first edge 12 allocated to the first limb 2 and a second edge 13 allocated to the second limb 3. Form-fitting elements 8 are disposed in the region of both edges 12, 13. The web elements 5 are connected to the fastening portions 6 of the first limb 2 and of the second limb 3 via the form-fitting elements 8. In the present embodiment, the form-fitting elements 8 comprise bores 9 and fastening elements 10. In order to form the profile 1 , web elements 5 are disposed on one side of the fastening portions 6 and fastening elements 10 are disposed on the other side of the fastening portions 6 and protrude through the opening 7 into the bore 9 of the web elements 5.
The fastening elements 10 are formed as a latching element and preferably have a button-like shape. The fastening elements 10 comprise pins 17 centrally provided with undercuts. The bores 9 of the web elements 5 have a cross-sectional extension on the side facing away from the fastening portion 6. The pin 17, which is formed conically at the free end, is deformed when being pressed into the bore 9, in order to be finally braced in a form-fitting manner in the cross- sectional extension. In this way, by means of the fastening element 10, the web element 5 is fixedly fastened on the first limb 2 or the second limb 3.
Fig. 2 shows in detail and in a three-dimensional manner the front face or rear face of a web element 5.
Fig. 3 shows the previously described web element 5 in a front view, in a plan view and as a cross-sectional view in plane A-A. Fig. 4 shows a side view and a cross-sectional view in plane B-B of the profile 1 according to fig. 1.
Fig. 5 shows an alternative embodiment of a profile 1 as a cross-sectional view and in a three- dimensional view. The profile 1 according to Fig. 5 likewise comprises a first limb 2 and a second limb 3. Both limbs 2, 3 consist of metallic material. The first limb 2 and the second limb 3 are connected to one another via a web 4. Thus the web 4 is formed from a plurality of web elements 5, wherein the web elements 5 are connected in a form-fitting manner to the first limb 2 and the second limb 3. The web elements 5 consist of a synthetic material which can be injection moulded. The web elements 5 are formed as plates and are substantially flat. The profile 1 is formed as a C-shaped profile and comprises fastening flanges 14 to receive dry elements. The two fastening flanges 14 are disposed parallel to one another. The first limb 2 and the second limb 3 each comprise a fastening portion 6. The fastening portion 6 is formed as a strip and both fastening portions 6 are disposed in the same horizontal plane. The two fastening portions 6 are formed from the first limb 2 and the second limb 3 and point towards each other. Openings 7 in the form of circular holes are introduced into the fastening portions 6. The web elements 5 are fastened in the openings 7.
In the case of the present embodiment, the web elements 5 are fastened to the fastening portions 6 in that in each case, two web elements 5 are disposed back-to-back with respect to each other and thus receive the fastening portions 6 of the first limb 2 and second limb 3 between them.
Each web element 5 comprises form-fitting elements 8 in the form of bores 9 and protrusions 11. Thus the bores 9 and protrusions 1 1 of the form-fitting elements 8 of the web elements 5 are congruent to one another. The protrusions 11 can be inserted into the bores 9 in a form-fitting manner and latch in the bores 9. The web elements 5 each comprise a bore 9 and a protrusion 11 on the first edge 12 and on the second edge 13. Thus, the arrangement of bore 9 and protrusion 11 on the first edge 12 has point symmetry with the arrangement of bore 9 and protrusion 11 on the second edge 13. In this respect, merely a single type of web elements 5 is sufficient to form the profile 1. A first web element 5 is fixed in the fastening portions 6 by the openings 7, and a second web element 5 is fastened, having been tilted by 180°, on the other web element 5. Thus the two web elements 5 receive the fastening portions 6 between them. In this embodiment, the two rear sides of the two web elements 5 face each other. Furthermore, the first edge 12 of one web element 5 is allocated to the second edge 13 of the other web element 5.
Fig. 6 shows in detail and in a three-dimensional manner the front face or rear face of a web element 5 according to Fig. 5.
Fig. 7 shows the previously described web element 5 in a front view as well as two cross- sectional views: one in plane C-C and one in plane E-E.
Fig. 8 shows a side view and a cross-sectional view in plane D-D of the profile 1 according to
Fig. 5. Fig. 9 shows a wall 15 comprising a plurality of profiles 1 according to Fig. 1 and a plurality of flat construction panels 16, which are fixed on the fastening flanges 14 of the profiles 1. The construction panels 16 are formed e.g. as gypsum plaster boards and are fixed in the fastening flanges 14 of the profile 1 with fastening means 17, e.g. in the form of screws. Fig. 10 shows a wall 15 comprising a plurality of profiles 1 according to Fig. 5 and a plurality of flat construction panels 16 which are fixed on the fastening flanges 14 of the profiles 1. The construction panels 16 are formed e.g. as gypsum plaster boards and are fixed in the fastening flanges 14 of the profile 1 with fastening means 17, e.g. in the form of screws.
