Precompressed Sealing Tape

Abstract

The precompressed sealing tape for sealing a joint has an elastically reexpandable foam strip, a wrapping, which at least partially surrounds the foam strip, and a strip-shaped element, which is made of stiff foam. The strip-shaped element is arranged in an area of the first transverse surface of the foam strip. A fastening means for attaching the strip-shaped element to a building component is arranged in an area of the strip-shaped element. A first section of the wrapping is arranged between the first transverse surface of the foam strip and the strip-shaped element.

What is claimed is: 
     
         1 . A precompressed sealing tape for sealing a joint, comprising:
 an elastically re-expandable foam strip, extending farther in a longitudinal direction than in a transverse direction, which comprises two lateral surfaces and first and second transverse surfaces, which connect the two lateral surfaces to each other,   a wrapping, which at least partially surrounds the foam strip,   a strip-shaped element, which is made of stiff foam and has a greater flexural strength in the transverse direction than the foam strip, wherein the strip-shaped element is arranged in an area of the first transverse surface of the foam strip; and   fastening means for attaching the strip-shaped element to a component to be installed in a building;   
       wherein a first section of the wrapping is arranged between the first transverse surface of the foam strip and the strip-shaped element, and 
       wherein the fastening means is arranged in an area of the strip-shaped element. 
     
     
         2 . The precompressed sealing tape of  claim 1  wherein the first transverse surface of the foam strip is fixedly connected to the strip-shaped element. 
     
     
         3 . The precompressed sealing tape of  claim 1  wherein the fastening means for fastening the strip-shaped element to the structural component is provided in an area of a side of the strip-shaped element which faces away from the first transverse surface of the foam strip. 
     
     
         4 . The precompressed sealing tape of  claim 3  wherein the fastening means is formed as a double-sided adhesive strip. 
     
     
         5 . The precompressed sealing tape of  claim 1  wherein the first section of the wrapping extends between the first transverse surface of the foam strip and the strip-shaped element all the way across the first transverse surface. 
     
     
         6 . The precompressed sealing tape of  claim 1  wherein the first section of the wrapping is arranged between the first transverse surface and the strip-shaped element only across a first part of the first transverse surface of the foam strip. 
     
     
         7 . The precompressed sealing tape of  claim 6  wherein a second section of the wrapping is arranged between the first transverse surface and the strip-shaped element across a second part of the first transverse surface of the foam strip, the second part being opposite the first part. 
     
     
         8 . The precompressed sealing tape of  claim 1  wherein the strip-shaped element has a flexural strength of more than 250 kPa. 
     
     
         9 . The precompressed sealing tape of  claim 1  wherein the strip-shaped element has a flexural strength of more than 400 kPa. 
     
     
         10 . The precompressed sealing tape of  claim 1  wherein the strip-shaped element has a flexural strength of more than 1,000 kPa. 
     
     
         11 . The precompressed sealing tape of  claim 1  wherein the wrapping comprises a tear-off tab extending in the longitudinal direction, which serves as a pulling element for releasing the foam strip and allowing its expansion. 
     
     
         12 . The precompressed sealing tape of  claim 1  wherein the wrapping is provided with at least one predetermined tear site extending in the longitudinal direction. 
     
     
         13 . The precompressed sealing tape of  claim 12  wherein the at least one predetermined tear site is a perforation line. 
     
     
         14 . The precompressed sealing tape of  claim 1  wherein the sealing tape is wound up into a roll. 
     
     
         15 . A structural component to be installed in a building, the structural component with a precompressed sealing tape fastened to it, the precompressed sealing tape comprising:
 an elastically re-expandable foam strip, extending farther in a longitudinal direction than in a transverse direction, which comprises two lateral surfaces and first and second transverse surfaces, which connect the two lateral surfaces to each other,   a wrapping, which at least partially surrounds the foam strip,   a strip-shaped element, which is made of stiff foam and has a greater flexural strength in the transverse direction than the foam strip, wherein the strip-shaped element is arranged in an area of the first transverse surface of the foam strip, and   fastening means for attaching the strip-shaped element to the structural component,   
       wherein a first section of the wrapping is arranged between the first transverse surface of the foam strip and the strip-shaped element, and 
       wherein the fastening means is arranged in an area of the strip-shaped element.
