Gap seal for building structures

Abstract

A permanently functional gap seal on structures, in particular building structures, ensures a reliable seal against penetrating moisture. A cover layer has a profile which can be adapted to an installation situation over a joint or on an inner or outer corner. The device has a central part and side wings on both sides of the central part. The side wings have contact surfaces with which they are adhesively attached to the building structures.

1 . A gap seal for a building structure, comprising: 
 a water-tight profile strip having a central part and side wings integrally formed laterally on said central part;    said side wings being formed of a relatively hard, relatively rigid material;    said central part being formed of a relatively soft, elastic material and having a material reserve allowing said side wings to move laterally apart from one another while remaining integrally connected with said central part.    
   
   
       2 . The gap seal according to  claim 1 , wherein said side wings have a length and contact surfaces over said length to be coated with a sealant and to be glued to members of the building structure.  
   
   
       3 . The gap seal according to  claim 1 , wherein said profile is in a form selected from the group consisting of a web form in strips, wound up to form a roll, and a sectional piece.  
   
   
       4 . The gap seal according to  claim 1 , wherein said profile strip is constructed as a corner element for an inner or outer corner.  
   
   
       5 . The gap seal according to  claim 1 , wherein said central part and said side wings are formed in a single co-extruded strip.  
   
   
       6 . The gap seal according to  claim 5 , wherein said side wings have ribs formed thereon.  
   
   
       7 . The gap seal according to  claim 1 , wherein said side wings have contact surfaces to be glued to building surfaces and the contact surfaces are profiled with formed-on ribs.  
   
   
       8 . The gap seal according to  claim 1 , wherein said profile strip has one of said side wings glued to a wall and the other one of said side wings disposed on a projecting length of a slab that projects beneath a masonrywork of the wall, and said other side wing is secured on the floor slab by a sealing layer made of resin.  
   
   
       9 . The gap seal according to  claim 1 , wherein said side wings are formed with substantially planar surfaces constructed in a rough state similar to a contact surface.  
   
   
       10 . The gap seal according to  claim 1 , wherein said central part of said profile strip extends freely into a joint for use in a joint seal for a settlement joint.
