Description

[0018] Further advantages and features emerge from the following description and from the accompanying drawings. In the drawings:

[0019] FIG. 1 is a schematic sectional view of a sealing device according to the invention, and

[0020] FIG. 2 is a schematic sectional view of a sealing device according to the invention in accordance with a further embodiment.

[0021] When the sealing device is used, drywall having double-layer cladding is preferably provided with a first cladding and a second cladding, each of which forms one of the two oppositely arranged wall surfaces of the drywall. The drywall also comprises a stand construction with a holding rail. The holding rail is preferably a floor profile that is firmly anchored on the floor, for example by means of dowels.

[0022] The wall surfaces usually have a single-layer cladding, i.e. the first and the second cladding each have a cladding part (gypsum wall) in the horizontal direction H.

[0023] In principle, in an alternative embodiment, the first and/or the second cladding of the drywall can have a plurality of cladding parts in the horizontal direction H, i.e. each of the wall surfaces can have multiple layers of cladding, in particular with two adjacent cladding parts in the horizontal direction H.

[0024] The first and the second cladding are each attached to the stand construction at a distance from the floor in the vertical direction V, as a result of which a double edge joint is formed with a first edge joint and a second edge joint. The first edge joint is formed in the form of a floor joint between a circumferential side of the first cladding and the floor, while the second edge joint is formed in the form of a floor joint between a circumferential side of the second cladding and the floor.

[0025] In order to seal the edge joints, the drywall also has a sealing device 1, the structure of which is described below with reference to FIG. 1. The sealing device 1 is also suitable for sealing at least one edge joint between the drywall and the ceiling and/or wall.

[0026] The sealing device 1 has a one-piece sealing profile 2 with a base body 3 and a sealing web 4. The sealing web 4 forms a support against which the corresponding cladding. The sealing web 4 extends perpendicularly away from the base body 3. The base body 3 forms the sealing portion of the sealing device 1, which sealing portion seals the edge joint. In particular, the cladding rests in this case with its circumferential side against a support of the base body.

[0027] The sealing web 4 extends in the vertical direction V in each case into a gap which is formed between the holding rail and the edge of the inner end face of the corresponding cladding adjacent to the circumferential side.

[0028] The sealing device 1 is an extruded profile. The sealing profile 2 consists of a plastics material, for example EPDM, PE foam, PP foam, PS foam, or particle foam. In principle, the sealing device 1 can be made of any material and in any way. Preferably, however, at least the sealing profile 2 is an extruded profile.

[0029] Furthermore, the sealing profile 2 can be sheathed at least in portions with a film.

[0030] In order to reliably seal the edge joint with the sealing device 1, the holding rail is aligned on the floor during the assembly of the drywall and then anchored in the floor. The sealing device 1 is provided separately from the holding rail and is fastened thereto via the fastening portion 5, preferably with an adhesive or a self-adhesive tape or other adhesive.

[0031] The cladding is now set up with its circumferential side on the sealing web 4, so that the edge of the end face rests against the sealing web 4 and the base body 3 is pressed against the floor, and is then fastened to the stand construction.

[0032] The possible further second cladding is fastened by means of a second sealing device 1 in an analogous manner opposite to the first cladding on the stand construction.

[0033] Since each cladding is placed on the sealing device 1 during assembly, it is ensured that the two edge joints each have a defined width in the vertical direction V, while the weight of the cladding ensures that each base body 3 rests sealingly against the floor.

[0034] In principle, the sealing device 1 can be used to seal any edge joint that is formed between the circumferential sides of two spaced-apart claddings and an adjacent floor, wall, or ceiling.

[0035] A sealing device according to a further embodiment will now be described with reference to FIG. 2.

[0036] In contrast to the embodiment shown in FIG. 1, the sealing device 1 has a sealing web 4 which is flush with an upper side of the base body 3. The sealing profile 2 is constructed in layers from a foam material, wherein two closed-cell foam material layers 7 enclose an open-cell foam material layer 8. In a particularly preferred embodiment, the sealing profile consists of an intumescent foam material.

[0037] The sealing profile 2 of the sealing device 1 has a slit 6 in FIG. 1 and in FIG. 2, which preferably extends perpendicularly and adjacent to the sealing web 4 over approximately half of the base body 3.

[0038] Alternatively, the sealing device 1 can also have any number of intumescent strips which are provided at any point on the sealing device. Intumescent strips can also be provided as a fire protection function, which strips are arranged, for example, in a recess in the base body. Additionally or alternatively, the sealing profile 2 can be formed from a material that comprises further fire protection additives.

[0039] In all embodiments, a fire protection design without intumescent strips or without intumescent material can be provided, in particular if the sealing profile 2 is formed from a temperature-resistant material.

[0040] Furthermore, the sealing device 1 ensures effective sealing of the edge joint with respect to air and sound. The sealing device 1 turns the drywall into a fire-safe construction, by means of which smoke, temperature, and fire can be prevented from spreading over to the side of the drywall that faces away from the fire.

[0041] The base body 3 of the sealing profile 2 ensures a defined joint width and also protects the cladding against moisture in or on the floor, in particular during the construction phase.

[0042] Furthermore, the sealing device 1 is a factory-made application solution with constant properties, which makes the sealing of edge joints with a consistently high quality easier.

[0043] The invention is not limited to the embodiments shown. In particular, individual features of one embodiment can be combined in any way with features of other embodiments, in particular independently of the other features of the corresponding embodiments.

[0044] Furthermore, each sealing device can be configured for single-layer and/or double-layer cladding.
