Joint-sealing tape and sealing arrangement with such sealing tape

Abstract

A joint-sealing tape can be used for sealing a joint between a first building part and a second building part with an elongated carrier and at least two separate sealing strips, which have a round cross section and are disposed on the carrier, spaced apart, side-by-side and running in the longitudinal direction of the carrier.

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 strips, which are disposed on the carrier, spaced apart, side-by-side and running in a longitudinal direction of the carrier,   wherein   the sealing strips have a round cross section.   
     
     
         2 . The joint-sealing tape according to  claim 1 , wherein the sealing strips are disposed on an outer rim of the carrier. 
     
     
         3 . The joint-sealing tape according to  claim 1 , wherein the sealing strips are firmly joined to the carrier at least over part of their circumference. 
     
     
         4 . The joint-sealing tape according to  claim 3 , wherein the sealing strips are firmly joined to the carrier over their entire circumference. 
     
     
         5 . The joint-sealing tape according to  claim 1 , wherein the sealing strips consist of a deformable material. 
     
     
         6 . The joint-sealing tape according to  claim 5 , wherein the sealing strips consist of an intumescent material. 
     
     
         7 . The joint-sealing tape according to  claim 5 , wherein the sealing strips 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, said sealing arrangement comprising:
 at least one first building part, one second building part and a joint-sealing tape according to  claim 1 , wherein a side with which the second building part bears on the first building part has a face (F 2 ) with a width (B 2 ) 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 ) is smaller than the width (B 1 )   wherein   the sealing strips are positioned in an outer region of the joint and are configured to seal the joint from outside.   
     
     
         10 . The sealing arrangement according to  claim 9 , wherein the sealing strips are disposed laterally on the second building part. 
     
     
         11 . The sealing arrangement according to  claim 9 , wherein a region of the carrier disposed between the points of attachment of the carrier to the sealing strips defines a support region, wherein the joint-sealing tape is configured in such a way that the support region of the carrier comes into contact with the second building part. 
     
     
         12 . The sealing arrangement according to  claim 9 , wherein, after application of the joint-sealing tape on the second building part, the sealing strips 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 , wherein the sealing strip has a predetermined radius (r) and the support region of the carrier has a width (b), wherein the width (b) is chosen in such a way as a function of the radius (r) and of the width (B 2 ) of the face (F 2 ) of the second building part that the width (b) corresponds at least to the width (B 2 ) but at most is large enough that a projecting length (h) is obtained. 
     
     
         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.
