Description

[0001] The invention relates to a supporting structure for a drywall partition, a framework for a drywall partition and a drywall partition.

[0002] Common drywall partitions consist of a framework with frame profiles, particularly wall profiles, floor profiles, and / or ceiling profiles made of metal, e.g., steel. Metal studs, especially steel, are arranged between the frame profiles. The entire structure can also be made of wooden beams.

[0003] Steel profiles, for example, have the disadvantage that their production and / or recycling cause environmental problems, particularly high CO2 emissions. The thin material thickness of approximately 0.6 mm can lead to cuts during processing, and the frame and upright profiles are susceptible to damage.

[0004] Wooden beams, on the other hand, are heavy and / or have a large volume, e.g., a large packing size. This leads to handling problems. It can also cause problems, such as efficiency issues regarding material requirements, transport, and / or storage.

[0005] The object of the invention is to create a supporting structure for a drywall partition, a framework for a drywall partition and a drywall partition, whereby the handling, in particular the manufacturing, is improved.

[0006] The problems are solved according to the invention by a supporting structure for a drywall according to claim 1, a framework for a drywall according to claim 20, and a drywall according to claim 21.

[0007] The support structure according to the invention for a drywall partition is, in particular, a drywall profile for a drywall partition. For example, the support structure is a stud profile, a frame profile, or a stiffening profile for a drywall partition. The support structure has a longitudinal beam. The longitudinal beam contains cellulose, and in particular consists of cellulose. It is preferred that the longitudinal beam is partially or completely recyclable. In particular, the longitudinal beam has rounded edges; in particular, all edges of the longitudinal beam are rounded. It is preferred that the edges and / or corners, in particular all edges and / or corners, of the longitudinal beam have a chamfer, preferably a round one. An advantage of the cellulose-containing longitudinal beam compared to a longitudinal beam made of metal is, for example,that the manufacturing process results in lower CO2 emissions, that screws are easier to screw in, and / or that there is better temperature insulation.

[0008] It is preferred that the longitudinal support is made of paper, in particular cardboard, and preferably consists entirely of it. Preferably, the paper of the longitudinal support consists of at least 90%, more preferably at least 95%, and particularly preferably at least 98% recycled paper. It is particularly possible that the paper of the longitudinal support consists of 100% recycled paper.

[0009] It is preferred that the longitudinal beam is a structural profile with a C-profile, a U-profile, an H-profile, an I-profile, a rectangular profile, or a hat profile. In particular, the C-profile can be a CW-profile or a CD-profile, and the U-profile can be a UW-profile or a UD-profile. The C-profile and / or the U-profile preferably has a web and a flange on each side of the web. In the case of the C-profile, it is preferred that the flanges have lips on their outer sides, especially those facing inwards. It is preferred that the edges of the flanges and / or the lips, preferably the outer edges, are rounded.

[0010] The flanges of the C- and / or U-profile can be arranged, for example, at right angles to the web. Alternatively, the flanges can be arranged at an angle to the web, particularly relative to a right-angled arrangement, inclined on one or both sides outwards or inwards. The flanges can be arranged, for example, at an angle of 70° to 110°, preferably 80° to 100°, to the web. The inclined flanges ensure that the C- and / or U-profiles, when inserted, for example, into another profile to be connected, or when receiving a corresponding profile, wedge themselves against the other profile for fastening. In this way, the inclined flanges can, for example, create a preload for clamping, e.g., to achieve an interference fit.

[0011] It is preferred that the longitudinal beam has several layers of cellulose.

[0012] Preferably, the longitudinal beam has 7-10 layers, in particular 8 layers of cellulose.

[0013] It is preferred that the multiple layers are glued and / or pressed together. Preferably, the layers are wet-strength, e.g., glued together using water-based adhesive.

[0014] It is preferred that a layer has a thickness of 0.5 to 0.9 mm, in particular 0.7 mm.

[0015] It is preferred that the longitudinal beam has a coating, particularly on the outside.

[0016] The coating is preferably water-repellent.

[0017] Preferably, the longitudinal beam has one or more water-repellent covering layers, which in particular cover the entire outside of the longitudinal beam.

[0018] It is preferred that the longitudinal beam has at least one through-hole, in particular for routing cables and / or pipes. If the longitudinal beam is designed as a C- or U-profile, the at least one through-hole extends through the web. The through-hole has a diameter of at least 20 mm, preferably at least 50 mm, and most preferably at least 100 mm. In particular, the through-hole is designed as a hole, preferably a complete hole, in the longitudinal beam. Instead of or in addition to the hole, the at least one through-hole can be designed as a pre-cut. For example, it is preferably possible for the longitudinal beam to have a pre-cut in the shape of an H or U, so that the pre-cut can be bent to create a through-hole, e.g., using a screwdriver. It is possible, for example, to...also that the pre-cutting is implemented as a perforation, in particular rectangular, round or oval, so that the perforation can be broken out to implement the process.

[0019] It is preferred that the at least one through-hole extends transversely through the longitudinal beam. Preferably, the at least one through-hole extends transversely to the longitudinal direction of the longitudinal beam.

[0020] It is preferred that the at least one through-hole is formed as a cutout, in particular as a punching or drilling, from the longitudinal beam.

[0021] It is preferred that the at least one through-hole be oval, round or rectangular.

[0022] It is preferred that the longitudinal beam has several through-holes, in particular arranged at equal intervals. In particular, the distance between the several through-holes is between 30 cm and 60 cm, preferably approximately 50 cm.

[0023] It is preferred that the longitudinal beam has a wall thickness of 5 mm to 8 mm, in particular 6 mm.

[0024] It is preferred that the longitudinal beam has a width between 20 mm and 200 mm, preferably between 45 mm and 100 mm, and particularly preferably a width of 48.8 mm or 74.8 mm or 98.8 mm.

[0025] It is preferred that the longitudinal beam has a depth between 20 mm and 100 mm, more preferably between 30 mm and 60 mm, and most preferably between 40 mm and 50 mm. It is also possible, for example, that the two flanges are of different lengths, so that, for example, one side has a depth of 50 mm and the other side a depth of 48 mm.

[0026] It is preferred that the longitudinal beam has a length between 2000 mm and 8000 mm, preferably between 2000 mm and 4000 mm and particularly preferably between 2500 and 4000 mm.

[0027] The stud frame according to the invention for a drywall partition comprises at least one stud profile and at least one frame profile connected to the stud profile. The stud profile is, for example, a wall profile, a floor profile, and / or a ceiling profile. It is preferred that the stud frame comprises several, in particular different, such stud profiles. The at least one frame profile is preferably connected perpendicularly to the floor profile and / or a ceiling profile. In particular, the at least one frame profile is arranged parallel to the at least one wall profile. It is possible, for example, that the stud frame also comprises at least one stiffening profile. The at least one stud profile and / or the at least one frame profile and / or the at least one stiffening profile constitute a load-bearing structure according to the invention.

[0028] The drywall partition according to the invention comprises a stud frame according to the invention and at least one panel covering the stud frame, in particular a gypsum plasterboard or gypsum fiberboard. Preferably, insulation, for example comprising rock wool or glass wool or a wood fiber insulation material, is arranged in the spaces between the stud frames.

[0029] It is preferred that the panels are screwed to the upright profile and / or the frame profile of the truss. The use of cellulose-based support structures for the truss is particularly advantageous in improving the insertion of screws, as the screws can be inserted with less pressure and / or self-tighten evenly into the support structures as they are turned.

[0030] In particular, the invention significantly simplifies the dismantling of a drywall partition, as the risk of injury, unlike with steel profiles, is minimal due to the use of cellulose. The supporting structure can be partially recycled along with the dismantled gypsum plasterboard or gypsum fiberboard for the production of new gypsum plasterboard or gypsum fiberboard (cradle-to-cradle). Furthermore, an established paper recycling process already exists that allows for 100% reuse of the supporting structure. This is only possible with steel profiles at a high energy cost.

[0031] The invention will now be explained in more detail with reference to preferred embodiments and the accompanying drawings. They show:

[0032] Fig. 1 is a schematic front view of an embodiment of a support structure according to the invention. Fig. 2 is a schematic, perspective partial view of an embodiment of a drywall partition according to the invention with an embodiment of a stud frame according to the invention and several embodiments of support structures according to the invention.

[0033] The supporting structure 10 made of Figure 1 It has a longitudinal beam 12 and consists in particular of this. The supporting structure 10 for a drywall partition 200 (see...) Figure 2 ) out of Figure 1 It is preferably a drywall profile, and especially preferably a frame profile.

[0034] The longitudinal beam 12 has the shape of a U-profile with two flanges 16 connected to each other via a web 14. The outer edges 20 of the flanges 16 are rounded, in particular have round chamfers, but can alternatively also be straight.

[0035] The longitudinal beam 12 shown consists of cellulose, preferably paper, particularly preferably cardboard. The longitudinal beam 12 consists of several layers 18 of cellulose. Schematically, in Figure 1 Five layers are shown, wherein it is preferred that the longitudinal beam 12 according to the invention has seven to ten, in particular eight, layers 18 of cellulose. The layers 18 consist in particular of cellulose. The layers 18 are in particular glued and / or pressed together. Preferably, the layers 18 are wet-strength, e.g., glued together by means of water-based adhesive. It is possible, for example (not shown), that the corners, i.e., in particular the connections between the flanges 16 and the webs 14, are rounded.

[0036] The dimensions of the longitudinal beam 12 are identified via the dimensions shown, where T represents the depth, B the width, L the length and D the wall thickness of the longitudinal beam 12.

[0037] The wall thickness D results in particular from the sum of the thicknesses of the layers 18.

[0038] It is preferred that the outside of the longitudinal beam 12 is coated, preferably with a water-repellent coating.

[0039] Figure 2 shows an embodiment of a drywall partition 200 according to the invention with an embodiment of a stud wall 100 according to the invention.

[0040] The framework 100 shows three supporting structures 10a, 10b.

[0041] The supporting structure 10a is a floor profile in the form of a frame profile, consisting of a longitudinal beam 12 with a U-profile. The supporting structure 10a exhibits, in particular, one, several, or all of the features of the supporting structure 10. Figure 1 on.

[0042] The supporting structure 10a shows two supporting structures 10b, preferably positively connected. The supporting structures 10b, which are preferably identical, are upright profiles. The supporting structures 10b are preferably designed as C-profiles with two flanges 16 connected via a web 14, wherein it is possible that the flanges 16 have lips 17 on their outer sides facing the interior of the supporting structure 10b. The outer edges of the lips 17 can, for example, be rounded. However, it is preferred that the flanges do not have lips 17.

[0043] The web 14 of the supporting structures 10b has, in particular oval, feedthrough openings 22, e.g. for the passage of (not shown) cables and / or pipes. Instead of or in addition to the illustrated design of the feedthrough openings 22 as holes, it is particularly possible that the feedthrough openings 22 are designed, preferably as H- or U-shaped, pre-cuts, so that the pre-cuts can be bent, e.g. by means of a screwdriver, to create a feedthrough.

[0044] One or more of the supporting structures 10a, 10b, 10b in particular contain cellulose, e.g. cellulose layers 18, and consist in particular of it.

[0045] The stud frame 100 is clad with panels 202, e.g., gypsum plasterboard or gypsum fiberboard. The panels 202 are screwed into the supporting structures 10a, 10b by means of screws 204a, 204b. The screws 204a pass through the panels 202 as well as the supporting structure 10a and the corresponding supporting structure 10b, so that in addition to attaching the panels to the stud frame 100, a screw connection between the supporting structure 10a and the supporting structures 10b is also achieved.

[0046] An insulation (not shown) is preferably arranged in an interior 206 of the framework 100, preferably between the framework 100 and the panels 202.

[0047] The flanges 16 are in Figure 1designed perpendicular to the web 14. Alternatively, a design is also possible in which the flanges 16 are inclined inwards or outwards, so that when connecting to another support structure, e.g. when inserting a support structure 10b into another support structure 10a, as in Figure 2 shown, resulting in a clamping of the flanges 16 of the support structure 10b against the inner sides of the flanges 16 of the support structure 10a and thus approximately a press fit connection of the support structures 10a, 10b.
