Description

[0001] The invention relates to a connecting profile for drywall panels with a first and a second profile leg for fastening a drywall panel in each case.

[0002] Flexible joint formation in drywall construction is currently achieved by placing a flexible profile, such as the applicant's profile with article number 153300, onto the joint and embedding it in joint compound. The applicant's known movement joint profile can be attached to the drywall panels with clips and fully embedded in joint compound on both sides. This allows movement joints to be created in gypsum plasterboard in wall or ceiling areas. The legs of the known profile are perforated to ensure good adhesion to the plaster. Alternatively, two profiles can be placed on top of each other, allowing movement to be accommodated by their relative movement. Milling a profile into the edge of the drywall panels to create corners is also a known method. With all these variations, movement absorption is limited, and a substructure is mandatory in the joint areas.

[0003] In drywall construction, the airtightness of a vapor barrier is essential to ensure the long-term functionality of the insulation layer. The vapor barrier must not be perforated to maintain the airtightness of the layer. For this reason, profiles, especially expansion joint profiles, should not be screwed directly to the drywall panels, as this creates the risk of the screws missing the substructure and thus damaging the vapor barrier. In corner areas, a sufficiently large substructure must always be used to which the drywall panels can be attached. The profiles are therefore not directly bonded to the drywall panels, but simply embedded in the joint compound.

[0004] The object of the present invention is therefore to further develop a connecting profile for drywall panels in such a way that a substructure in the corner area, where drywall panels meet, can be avoided.

[0005] This problem is solved according to the invention by a connecting profile for drywall panels with a first and a second profile leg for fastening a drywall panel each, wherein at least one profile leg has a pocket for receiving a drywall panel and / or a screw protection zone is provided in the area of ​​at least one profile leg for covering or receiving the screw tip of a screw used to fasten a drywall panel. If a corresponding pocket for receiving a drywall panel is provided, the connecting profile can be attached to one end of a drywall panel and the drywall panel and the connecting profile can be screwed together in this area. By screwing the connecting profile to the drywall panel, a substructure can be dispensed with.For example, beam or girder cladding can be manufactured entirely without a substructure. This saves material and time. Furthermore, the cladding can be made smaller. If at least one profile leg includes a screw protection zone to cover or accommodate the screw tip, it can also prevent the vapor barrier from being perforated.

[0006] A pocket can not only be arranged on a profile leg, but the profile leg can also have the pocket. In particular, the pocket can be materially bonded to the profile leg.

[0007] The profile legs can be rigidly connected or joined by a flexible connector. If a flexible connector is used, it can be larger or wider than those found in conventional profiles, as the connector profile, with its integrated pocket and / or screw guard, can be screwed to the drywall panel. This results in a more secure connection between the profile and the drywall panels than using only clips. A larger flexible connector also allows for greater movement within the joint.

[0008] The pocket can have a U-shaped cross-section. This makes it particularly easy to insert an edge or end of a drywall panel into the pocket. The pocket then surrounds the end of the drywall panel along one narrow side.

[0009] A drywall panel can be fitted into a particularly tight fit against a profile leg if the profile leg forms a section of the pocket.

[0010] Particular advantages arise when the pocket tapers towards its opening. The connecting profile can then be clamped to the drywall panel via the pocket. In particular, this allows the connecting profile to be pre-positioned on the drywall panel and subsequently fixed to it with a screw.

[0011] Screw protection zones can be provided at different positions of the connecting profile, in particular regardless of the length and / or width of the profile legs.

[0012] The screw protection zone prevents damage to the vapor barrier, thus enabling risk-free screwing of the connecting profiles. Furthermore, the substructure can be omitted in a corner area, saving time and material.

[0013] At least one profile leg can have a plastering edge in the area of ​​the flexible connecting element. This allows the profile legs to still be plastered over. The plastering edge is preferably located directly next to the flexible connecting element, and in particular not on the flexible connecting element itself.

[0014] The flexible connecting element can be designed as a film hinge, accordion-style, as a connecting web with a thinner profile than the profile leg, and / or made of a different material, particularly rubber, TPF, TPU, silicone, EPDM, and / or nitrile, than the profile legs. The profile legs can, for example, be made of (rigid) PVC. Such a design of the connecting web results in particularly good flexibility. EPDM is especially suitable for high temperature and weather resistance. Nitrile offers good resilience after compression. Silicone is particularly suitable for high temperature ranges and chemical resistance.

[0015] The connection profile according to the invention is particularly easy to process when it is made of plastic, in particular PVC, TPF, TPU, silicone, EPDM and / or nitrile. In particular, this makes it possible to produce the connection profile by extrusion.

[0016] A particularly good connection between the connecting element and the profile legs is achieved when the profile legs and the connecting element are co-extruded.

[0017] At least one profile leg can have a textured surface, in particular a ribbed pattern. This results in good adhesion with plaster applied to the profile leg.

[0018] A screw marking may be provided on at least one profile web. This indicates the position at which a screw, when inserted at a right angle into the profile web, will almost certainly be screwed into the screw protection zone.

[0019] The screw protection zone can be designed as a hollow profile. This hollow profile can be partially open, for example, slotted. However, it is preferred that the hollow profile be completely closed. The screw tip can thus penetrate the cavity formed by the hollow profile, but not pass through it. This ensures secure screwing of the connecting profile to a drywall panel in critical areas.

[0020] Alternatively, the screw protection zone can be designed as a solid body. For example, the screw protection zone can be made of hard rubber, ensuring that a screw does not penetrate the screw protection zone, especially the hard rubber.

[0021] Further advantages arise when the screw protection zone is adjacent to a pocket. This allows a screw to be driven through the pocket and the drywall panel within it into the screw protection zone.

[0022] A wall of a screw protection zone can form a wall of the pocket. Therefore, the screw protection zone and the pocket can share a common wall.

[0023] The screw protection zones of two profile legs can each have a wall arranged at a 45° angle to the corresponding profile leg. If the two screw protection zones of the two profile legs are connected, either end-to-end or by one or more screws, the connecting profile can form a corner with two surfaces at a 90° angle to each other. The connecting profile can thus be used for a further purpose.

[0024] The connecting profile can be symmetrical with respect to a plane of symmetry passing through the connecting element or a connection area of ​​the profile legs. This results in particularly simple processing, as the orientation of the connecting element does not need to be taken into account.

[0025] Further features and advantages of the invention will become apparent from the following detailed description of exemplary embodiments of the invention with reference to the figures in the drawing, which show essential details of the invention, as well as from the claims. The features shown therein are not necessarily to scale and are depicted in such a way that the inventive features can be clearly seen. The various features can be implemented individually or in any combination in variants of the invention.

[0026] The schematic drawing shows exemplary embodiments of the invention in various stages of use, which are explained in more detail in the following description.

[0027] They show: Fig. 1a a perspective view of a first connection profile; Fig. 1b a front view of the connection profile of the Fig. 1a; Fig. 2 the first connecting profile that is connected to drywall panels; Fig. 3 a schematic representation of the problem arising in the prior art; Fig. 4 a schematic representation to illustrate the application of the first connection profile and the associated advantages; Fig. 5 a front view of a second connecting profile; Fig. 6.

[0028] The Fig. 1a, Fig. Figure 1b shows a first connecting profile 10 with a first profile leg 12 and a second profile leg 14. In the illustrated embodiment, the first and second profile legs 12, 14 are at a 90° angle to each other. The first and second profile legs 12, 14 each serve to fasten a drywall panel. The drywall panel is to be screwed to the profile legs 12, 14. To prevent damage to an underlying vapor barrier, a screw protection zone 16, 18 is provided on each profile leg 12, 14. The screw protection zones 16, 18 are hollow, in particular designed as hollow profiles. They are closed on all sides. They are located on the rear faces of the profile legs 12, 14. Only one screw protection zone 16, 18 is shown for each profile leg 12, 14. However, multiple screw protection zones 16, 18 for each profile leg 12, 14 are also conceivable.Different numbers of screw protection zones 16, 18 are conceivable on each profile leg 12, 14. Furthermore, positions for the screw protection zones 16, 18 other than those shown are conceivable. On the sides of the profile legs 12, 14 facing away from the screw protection zones 16, 18, screw markings can be provided to indicate the points where screws can be inserted into the profile legs 12, 14 so that a screw tip enters a screw protection zone 16, 18.

[0029] The connecting profile 10 is preferably made of plastic, in particular by extrusion. The connecting profile 10 has a substantially L-shaped cross-section. The screw protection zones 16, 18 share a common wall with the profile legs 12, 14. In particular, a wall of the profile legs 12, 14 also forms part of, and thus a wall of, the screw protection zones 16, 18.

[0030] In the Fig. 2 The connecting profile 10 is connected to drywall panels 20, 22. In particular, the drywall panels 20, 22 are connected to the profile legs 12, 14 on the sides of the profile legs 12, 14 where no screw protection zone 16, 18 is present. The screws 24, 26 are screwed into the drywall panels 20, 22, for example, gypsum plasterboard, at locations such that the screws 24, 26, which are longer than the thickness of the drywall panels 20, 22, protrude into the screw protection zones 16, 18. In particular, the free ends or tips 28, 30 of the screws 24, 26 are located within the screw protection zones 16, 18 and do not penetrate them to the outside.

[0031] In the Fig. Figure 3 describes the problem described in the prior art. Drywall panels 20, 22 are screwed to a substructure 32, with a vapor barrier 34 positioned between the drywall panels 20, 22 and the substructure 32. The vapor barrier 34 is therefore perforated by the screws. In the corner area, there is also the risk that the screws will not penetrate the substructure 32 or that the screws will be driven in so far laterally that the substructure will chip.

[0032] In the Fig. Figure 4 shows the application of the connecting profile 10. The connecting profile 10 is positioned in the corner area of ​​the substructure 32. The drywall panels 20, 22 are screwed to the corner profile 10, with the vapor barrier 34 running between the connecting profile 10 and the substructure 32. A flexible insulation material 36 can be slightly compressed by the screw protection zones 16, 18. The screws 24, 26 do not damage either the vapor barrier 34 or the insulation material 36. Outside the corner area, the vapor barrier perforated by the screws can be sealed by a nail strip or a counter batten (not shown here).

[0033] The Fig. Figure 5 shows another embodiment of a connecting profile 100 with a first profile leg 112 and a second profile leg 114. The profile legs 112 and 114 are connected to each other by a connecting element 110. The connecting element 110 is flexible, so that, in contrast to the rigid connecting profile 10 of the preceding figures, the connecting profile 100 is flexible; in particular, the profile legs 112 and 114 can assume different angular positions relative to each other. Alternative embodiments of the connecting element 110 are conceivable. It should merely allow a certain relative movement of the profile legs 112 and 114. The connecting element 110 can be thinner than the profile legs 112 and 114. An embodiment with a rigid connecting element 110 is also conceivable, so that the connecting profile 100 is rigid overall.

[0034] Screw protection zones 116 and 118 are also provided on the profile legs 112 and 114. These zones are hollow, specifically designed as hollow profiles, and are circumferentially closed. The screw protection zones 116 and 118 adjoin pockets 120 and 122, which serve to accommodate drywall panels. The pockets 120 and 122 taper towards their opening. This allows the connecting profile 100 to be clamped to a drywall panel. The pockets 120 and 122 each share a wall 124 and 126 with the profile legs 112 and 114. They also share a wall 128 and 130 with the screw protection zones 116 and 118. The walls 132, 134 of the screw protection zones 116, 118 have an angle of 45° to the profile legs 112, 114. This means that the angle between the walls 132, 134 in the position shown is approximately 90°.When the walls 132, 134 are brought close together, a corner profile can be created so that the profile legs 112, 114 have an angle of approximately 90° to each other.

[0035] In the area of ​​the connecting element 110, the profile legs 112, 114 each have a plaster edge 136, 138. To improve plaster adhesion, the upper surfaces 140, 142 of the profile legs 112, 114 are profiled, in particular grooved. The walls 144, 146 form the undersides of the pockets 120, 122 and serve as a stop for the drywall panels that are inserted into the pockets 120, 122. Furthermore, the walls 144, 146 stiffen the connecting profile 100.

[0036] The connecting element 110 can be made of a different material than the rest of the connecting profile 100. The connecting profile 100 can be manufactured by extrusion. The connecting element 110 and the rest of the connecting profile 100 can be co-extruded. The profile legs 112, 114 can have screw markings.

[0037] The Fig. Figure 6 shows the use of the connecting profile 100 in the roof area of ​​a house. A substructure 152 is attached to roof beams 150. Drywall panels 20, 22 are screwed to the substructure 152. The drywall panels 20, 22 are inserted into the pockets 120, 122 of the connecting profile 100 and screwed to the connecting profile 100 there with screws 24, 26. The screws 24, 26 protrude into the screw protection zones 116, 118, so that they do not damage a vapor barrier 34. To ensure that the connecting profile 100 maintains the vapor barrier 34, the screws 24, 26 are screwed into the pockets 120, 122 of the connecting profile 100. Fig. When the part in position 6 is shown, it was slightly deformed in the area of ​​the connecting element 110.

[0038] The Fig. Figure 7 shows an alternative application of the connecting profile 100. For example, a substructure 162 can be attached to the pillar 160 to clad it. The connecting profile 100 can be deformed in the area of ​​the connecting element 110 so that the walls 132, 134 are arranged at a small distance from each other, and in particular, are aligned parallel to each other. The connecting profile 100 thus constitutes a corner profile. Drywall panels 20, 22 can be inserted into the pockets 120, 122 and screwed to the connecting profile 100 by means of screws 24, 26. The screws 24, 26 are screwed into the screw protection zones 116, 118. Since the walls 164, 166 have an angle of 45° to the walls 132, 134 or are aligned parallel to the profile legs 112, 114, they are shown in the representation of the Fig. The 7 elements are arranged at a 90° angle to each other and can be supported at the corner of the pillar 160. No substructure is necessary in the corner area.

[0039] The Fig. Figure 8 shows another embodiment of a connecting profile 200. The connecting profile 200 corresponds essentially to the connecting profile 100, but does not have screw protection zones 116, 118. The elements corresponding to the elements of the connecting profile 100 are therefore provided with the same reference numerals. The profile legs 112, 114 may have screw markings.

[0040] One initial application of the 200 connection profile is in the Fig. Figure 7 shows how it is used to clad pillar 160. The connecting profile 200 was deformed in the area of ​​the connecting element 110 so that the walls 210 and 212 are aligned parallel to each other, and the connecting profile 200 forms a corner profile. The walls 210 and 212 are connected to each other by a screw 214 to fix the connecting profile 200 in the position shown.

[0041] Drywall panels 20a, 22a are inserted into the pockets 120, 122 of the connecting profile 200 and screwed in place using screws 24a, 26a. Since the connecting profile 200 has no screw guards, the screws 24a, 26a protrude into the column 160 and are screwed to it. The connecting profile 200 provides a space-saving design for the corner of the cladding of the column 160.

[0042] In the Fig. Figure 9 shows an example of a corner cladding without a connecting profile according to the invention. Drywall panels 20, 22 are connected to a wall 310 via a substructure 300. The drywall panels 20, 22 are screwed to the substructure 300. The corner area of ​​the drywall panels 20, 22 is covered by a corner profile 312.

[0043] A more space-saving design is achieved in the Fig. 10. There, the drywall panels 20 and 22 are connected to each other via the connecting profile 200, which also serves as a corner profile. The drywall panels 20 and 22 are inserted into the pockets 120 and 122 and screwed to the connecting profile 200. It can be seen that a substructure is not required.
