Abstract

Furthermore, the invention relates to a sealing arrangement for sealing of building structure joints, especially for sealing against sound and/or smoke and if applicable against fire, with such a sealing tape.

First claim

The invention claimed is:

1. A joint-sealing tape for sealing a joint between a first building part and a second building part, said joint-sealing tape comprising:
an elongated carrier, and
at least two separate sealing elements of predetermined width (c), which are disposed on one side of the carrier, spaced apart, side-by-side and running in a longitudinal direction of the carrier, and which each have two oppositely disposed broad sides as well as two narrow sides running transversely relative to the broad sides and connecting them, wherein the sealing elements are disposed with one broad side on the carrier,
wherein
the sealing elements are each joined firmly to the carrier only at respective outer rim regions of said joint-sealing tape and only via part of their broad side.

2. The joint-sealing tape according to claim 1 , wherein the sealing elements are disposed in such a way on the carrier that parts of the sealing elements that are joined firmly to the carrier respectively form an outer region, and parts that are not joined firmly to the carrier form an inner region, wherein the inner regions face one another.

3. The joint-sealing tape according to claim 2 , wherein the carrier has three regions, two regions on which the sealing elements are disposed, which form the two outer regions, and one region between, which forms the middle region, wherein parts of the two outer regions of the carrier, on which the sealing elements are not firmly joined to the carrier, respectively adjoin the middle region of the carrier and together therewith form a support region for application on a building part.

4. The sealing arrangement according to claim 3 , wherein the width of said middle region is broader than a distance between inner lateral sides of said sealing elements.

5. The joint-sealing tape according to claim 1 , wherein the sealing elements consist of a deformable material.

6. The joint-sealing tape according to claim 5 , wherein the sealing elements consist of an intumescent material.

7. The joint-sealing tape according to claim 5 , wherein the sealing elements consist of one piece made from one material or of multiple parts made from several materials and exist as a layered body.

8. The joint-sealing tape according to claim 1 wherein the carrier consists of a plastic film, of a fabric, or of a nonwoven.

9. A sealing arrangement for sealing a joint between two juxtaposed building parts, the sealing arrangement comprising:
at least one first building part, one second building part and a joint-sealing tape according to claim 1 , wherein the side with which the second building part bears on the first building part has a face (F 2 ) with a width (B 2 ; p) and the first building part has a face (F 1 ) with a width (B 1 ), on which the second building part bears, with the condition that the width (B 2 ; p) is smaller than the width (B 1 ),
wherein
the sealing elements are positioned in an outer region of the joint and seal the joint from outside.

10. The sealing arrangement according to claim 9 , wherein the sealing elements are disposed laterally on the second building part.

11. The sealing arrangement according to claim 9 , wherein the joint-sealing tape is disposed on the second building part in such a way that a side of the carrier disposed opposite the sealing elements comes into contact with the second building part and the narrow sides, facing one another, of the sealing elements respectively come into contact with the first building part.

12. The sealing arrangement according to claim 9 , wherein, the sealing elements wrap around and are applied on opposite faces, which are joined by the face (F 2 ), so that the sealing elements have a projecting length (h) relative to the face (F 2 ) of the first building part, wherein the projecting length (h) points in the direction of the face (F 1 ) of the first building part.

13. The sealing arrangement according to claim 12 , with a joint-sealing tape, wherein the broad sides of the sealing elements have a predetermined width (c), each outer region of the sealing elements has a width (a) and the support region of the carrier has a width (b), wherein, for given width (c) and given width (B 2 ; p), the width (a) is chosen as a function of the width (B 2 ; p) of the second building part in such a way that the width (b) of the support region of the carrier corresponds to at least the width (p) and the width (t) of the middle region of the joint-sealing tape is smaller than the width (p).

14. The sealing arrangement according to claim 9 , wherein the first building part is a wall, a ceiling or a floor of a building structure and the second building part is a frame profile of a drywall studwork.
