Connector for concrete panels

Abstract

Connectors for connecting preformed concrete panels, which connectors have doubletee flanges extending from a center flange, forming a U shape, with the flanges twisted at their ends an angle of 90 degrees from the center, forming a curved surface between the ends and the center flange, the connectors carried in and having the center flanges flush with the sides of the panels, each center flange meeting a like center flange in an adjoining panel, with the center flanges welded together to connect the concrete panels.

1 . A connector for connecting adjacent concrete panels which comprises 
 a flat center flange.    a pair of side flanges connected to said center flange at a 90° angle, forming a U shape,    said side flanges having ends which are twisted at a 90° angle to the center flange, forming curved surfaces between said center flange and said side flange ends.    
   
   
       2 . A connector as defined in  claim 1  which is formed from a single metallic strip.  
   
   
       3 . A connector as defined in  claim 1  in which 
 said side flange curved surfaces have at least one opening therein.    
   
   
       4 . A connector as defined in  claim 1  in which 
 said center flange is eight inches long,    said side flanges are six inches long,    said center flange is two inches high, and    said center and side flanges are of one quarter inch thickness.    
   
   
       5 . A connector as defined in  claim 2  in which 
 said metallic strip is of stainless steel.
