Abstract

A sealing profile can be used for an edge joint formed between a floor and adjacent cladding of drywall. The sealing profile has a base body for sealing the edge joint. The base body has an upper portion close to the cladding and an opposite bottom portion. The upper portion has an upper side which forms a support for the cladding. The sealing profile also has a lateral fastening portion running towards the base body for fastening the sealing profile to a lateral holding rail of the drywall. The fastening portion is only firmly connected to the base body via the bottom portion. The base body also has a side surface which is directly opposite the fastening portion and which is not connected to the opposite region of the fastening portion. Drywall can contain such a sealing profile.

First claim

The invention claimed is:

1. A sealing profile for an edge joint formed between a floor and adjacent cladding of drywall, the sealing profile comprising:
a base body for sealing the edge joint, the base body having
an upper portion having an upper
side which forms a support for the cladding, and
an opposite bottom portion, and

a lateral fastening portion that fastens the sealing profile to a lateral holding rail of the drywall, wherein the fastening portion is only connected to the base body via the bottom portion,
wherein the base body has a side surface which is directly opposite the fastening portion and which is not connected to an opposite region of the fastening portion.

2. The sealing profile according to claim 1 , wherein the upper portion is connected exclusively to the bottom portion.

3. The sealing profile according to claim 1 , wherein the fastening portion forms a sealing web which is a lateral contact surface for the cladding and is configured to seal a gap between the holding rail of the drywall and the cladding.

4. The sealing profile according to claim 3 , wherein the sealing web extends vertically beyond a level of the upper side of the upper portion in an unassembled and unloaded state.

5. The scaling profile according to claim 3 , wherein the sealing web ends at a height of the upper side of the upper portion in an unassembled and unloaded state.

6. The sealing profile according to claim 1 , wherein the base body or the upper portion is a hollow profile having at least one cavity.

7. The sealing profile according to claim 1 , wherein the sealing profile has a fastening element attached to the fastening portion.

8. The sealing profile according to claim 1 , wherein the bottom portion is formed in one piece with the upper portion.

9. The sealing profile according to claim 1 , wherein the bottom portion merges in one piece into the fastening portion.

10. The sealing profile according to claim 1 , wherein the fastening portion and the base body are entirely in one piece.

11. The sealing profile according to claim 10 , wherein the upper portion is separated from the fastening portion by an incision or a gap.

12. The sealing profile according to claim 1 , wherein the fastening portion is formed from a different material than the upper portion and/or the bottom portion.

13. The sealing profile according to claim 12 , wherein the fastening portion is formed in one piece together with the bottom portion and forms an L-shaped cross section in combination therewith, and wherein the upper portion is fastened to the bottom portion.

14. The sealing profile according to either claim 12 , wherein the upper portion is separated from the fastening portion by a gap.

15. The sealing profile according to claim 1 , wherein the upper portion is formed from an open-cell foam, and/or
wherein the bottom portion and/or the fastening portion is/are formed from a plastic material or a closed-cell foam.

16. Drywall, comprising:
the sealing profile according to claim 1 ,
a holding rail, and
cladding which forms a wall surface of the drywall,
wherein the cladding rests with a circumferential side against the support of the upper portion.
