Abstract
A joint-sealing tape is useful for sealing building-structure joints, especially for sealing against sound and/or smoke and if necessary against fire. In particular, the joint-sealing tape is suitable for sealing a joint between a first building part and a second building part, with a sealing element and an adhesive layer, which sealing element has a predetermined geometry. Furthermore, a sealing arrangement contains such a sealing tape and is suitable for sealing of building structure joints, especially for sealing against sound and/or smoke and if applicable against fire.
Claims20
A joint-sealing tape for sealing a joint between a first building part and a second building part, said joint-sealing tape comprising:
- a seal including foam, sponge rubber, or cellular rubber and having a profile which is a round or polygonal profile and which is not hollow, and
- an adhesive layer including a first side directly or indirectly coupled to a first area of the seal and a second side opposing the first side, the second side including an adhesive material for attachment to the first building part, the adhesive layer unattached to a second area of the seal facing the second building part so that the second building part is free to move relative to the second area of the seal, wherein the seal has a predetermined geometry, wherein the foam, sponge rubber, or cellular rubber is an intumescent material, wherein a length of the adhesive layer is less than or substantially equal to a total length of an outer surface of the seal, and wherein the adhesive layer extends from the seal in a first direction with respect to a longitudinal axis of the seal in an uninstalled state and extends from the seal in a second direction with respect to the longitudinal axis of the seal in an installed state, the second direction extending in a same direction as a surface of the first building part and different from the first direction.
A joint-sealing tape for sealing a joint between a first building part and a second building part, said joint-sealing tape comprising:
- a seal including foam, sponge rubber, or cellular rubber and having a profile which is a round or polygonal profile and which is not hollow, and
- an adhesive layer including a first side directly or indirectly coupled to a first area of the seal and a second side opposing the first side, the second side including an adhesive material for attachment to the first building part, the adhesive layer unattached to a second area of the seal facing the second building part so that the second building part is free to move relative to the second area of the seal, wherein the seal has a predetermined geometry, wherein the foam, sponge rubber, or cellular rubber is an intumescent material, wherein a length of the adhesive layer is less than or substantially equal to a total length of an outer surface of the seal, and wherein the adhesive layer and the seal form a first angle in an uninstalled state and wherein the adhesive layer and the seal form a second angle in an installed state which is different from the first angle.
