Abstract
A drywall can be used as an attachment to a connecting building element. The drywall includes a connecting profile, at least one drywall panel, and at least one flat sealing device. The flat sealing device extends in an extent direction and has, transverse thereto, a retaining portion for positioning between a base portion and the connecting building element, a sealing portion, and a positioning portion for positioning on an outer side of the drywall panel. The flat sealing device is so disposed that a cavity is formed between an edge of the drywall panel, the connecting building element, the limb portion of the connecting profile, and the sealing portion.
Claims14
1:
- A drywall for attachment to a connecting building element, the drywall comprising:
- a connecting profile, which has, extending in an extent direction, a profile piece with a U-shaped cross section, wherein the cross section of the profile piece has a base portion with oppositely disposed edges transverse to the extent direction, wherein a limb portion protrudes from the oppositely disposed edges;
- at least one drywall panel, which is fastened to an outer face of a limb portion of the U-shaped cross section of the profile piece, such that the drywall panel protrudes transversely from the connecting building element;
- and
- at least one flat sealing device, which extends in the extent direction and has, transverse thereto, a retaining portion for positioning between the base portion and the connecting building element, a sealing portion and a positioning portion for positioning on an outer side of the drywall panel, wherein the flat sealing device is so disposed that a cavity is formed between an edge of the drywall panel, the connecting building element, the limb portion of the connecting profile and the sealing portion.
2 more elements
2:
- The drywall according to claim 1, wherein
- the flat sealing device is coated or equipped in the region of the sealing portion with an intumescent material, so that the cavity becomes completely or partly filled by the intumescent material being formed under the effect of heat, or the sealing portion comprises an ablatively acting fire-protection additive.
3:
- The drywall according to claim 1, wherein
- the flat sealing device is equipped in the region of the sealing portion with at least one kinking point, in order to form at least two segments of the sealing portion that can be tilted toward one another, at least one of which is oriented at an inclination or transverse to the extent of the limb portion of the profile piece.
4:
- The drywall according to claim 3, wherein
- the flat sealing device is equipped in the region of the sealing portion with three kinking points, so that two segments of the sealing portion that can be tilted toward one another form a V-like shape.
5:
- The drywall according to claim 4, wherein
- the V-like shape of the segments of the sealing portion point in the direction of the limb portion or in a direction opposite thereto.
6:
- The drywall according to claim 1, wherein
- the positioning portion of the flat sealing device 1 is equipped with a sealing element, in order to seal a gap relative to the positioning portion and the drywall panel.
7:
- The drywall according to claim 1, wherein
- a projecting stop element is provided between the retaining portion and the sealing portion.
8:
- The drywall according to claim 3, wherein
- the at least one kinking point functions as a positioning and mounting aid between the retaining portion and the sealing portion.
9:
- A flat sealing device for a drywall,
- wherein the flat sealing device is elongated in an extent direction and, transverse thereto, has a retaining portion, a sealing portion and a positioning portion,
- wherein the sealing portion comprises, at least on one side, an intumescent material, or
- wherein the sealing portion comprises an ablatively acting fire-protection additive.
1 more element
10:
- The flat sealing device according to claim 9, wherein
- the flat sealing device is equipped in the region of the sealing portion with kinking points, in order to form several segments of the sealing portion that can be tilted toward one another.
(canceled)
12:
- The drywall according to claim 1, wherein the connecting building element is selected from the group consisting of a room ceiling, a floor, and a solid wall.
13:
- The drywall according to claim 1, wherein
- a projecting stop element is provided between the retaining portion and the sealing portion, and
- wherein the projecting stop element is a bead protruding in the direction of the cavity.
14:
- A method of making the drywall according to claim 1, the method comprising:
- attaching the flat sealing device to the drywall panel,
- wherein, upon said attaching, the flat sealing device is disposed such that a cavity is formed between an edge of the drywall panel, the connecting building element, the limb portion of the connecting profile and the sealing portion.
