Intumescent sealing element for head-of-wall joints

Abstract

A sealing element for sealing a gap between a support structure and a track, where the track includes a horizontal main track section and track side sections that extend vertically from the main track section, is disclosed. The sealing element includes an insulating material strip which at least partially contains an intumescent material. The insulating material strip abuts the horizontal main track section of the track and is disposed between the track and the support structure.

What is claimed is: 
     
         1 . A sealing element for sealing a gap between a support structure and a track, wherein the track includes a horizontal main track section and track side sections that extend vertically from the main track section, comprising:
 an insulating material strip which at least partially contains an intumescent material;   wherein the insulating material strip abuts the horizontal main track section of the track and is disposed between the track and the support structure.   
     
     
         2 . The sealing element according to  claim 1 , further comprising an adhesive layer disposed on the insulating material strip. 
     
     
         3 . The sealing element according to  claim 1 , wherein a width of the insulating material strip corresponds to a width of the track. 
     
     
         4 . The sealing element according to  claim 1 , wherein a width of the insulating material strip is broader than a width of the track. 
     
     
         5 . The sealing element according to  claim 1 , wherein the insulating material strip at least partially contains a compressible material. 
     
     
         6 . The sealing element according to  claim 1 , wherein the insulating material strip at least partially contains an acoustically insulating material. 
     
     
         7 . The sealing element according to  claim 1 , further comprising a sealing layer disposed between the insulating material strip and the horizontal main track section of the track. 
     
     
         8 . The sealing element according to  claim 7 , wherein the sealing layer is an acoustically insulating material and/or a material that seals against cold gases and smoke. 
     
     
         9 . The sealing element according to  claim 1 , further comprising a sealing layer disposed between the insulating material strip and the support structure. 
     
     
         10 . The sealing element according to  claim 9 , wherein the sealing layer is an acoustically insulating material and/or a material that seals against cold gases and smoke. 
     
     
         11 . The sealing element according to  claim 1 , further comprising:
 a sealing layer disposed between the insulating material strip and the support structure; and   a support layer disposed between the insulating material strip and the horizontal main track section of the track.   
     
     
         12 . The sealing element according to  claim 11 , wherein the sealing layer is a first strip and a second strip and wherein the first strip and the second strip are disposed at respective ends of the insulating material strip. 
     
     
         13 . The sealing element according to  claim 12 , wherein a total width of the first strip and the second strip is smaller than a width of the track. 
     
     
         14 . A method for attaching a sealing element to a support structure for sealing a gap between the support structure and a track, wherein the track includes a horizontal main track section and track side sections that extend vertically from the main track section, comprising the steps of:
 positioning the sealing element on the track; and   after positioning the sealing element on the track, fixing the track and the sealing element to the support structure by penetrating a fastener through the track and the sealing element and into the support structure.   
     
     
         15 . The method according to  claim 14 , wherein the sealing element is an insulating material strip which at least partially contains an intumescent material. 
     
     
         16 . The method according to  claim 14 , wherein a width of the sealing element strip corresponds to a width of the track. 
     
     
         17 . The sealing element according to  claim 14 , wherein a width of the sealing element is broader than a width of the track. 
     
     
         18 . The method according to  claim 14 , wherein a sealing layer is disposed on a side of the sealing element. 
     
     
         19 . The method according to  claim 18 , wherein the sealing layer is an acoustically insulating material and/or a material that seals against cold gases and smoke. 
     
     
         20 . The method according to  claim 18 , wherein a support layer is disposed of a second side of the sealing element.
