Strip-shaped connection element for a steel-concrete connection

Abstract

A connection element formed of a strip of a corrugated sheet and including a plurality of bearing surfaces ( 3 ) spaced from each other and located in a common plane; at least one attachment opening ( 6, 7 ) formed in at least one bearing surface ( 3 ); a plurality of free-lying top surfaces ( 4 ) extending parallel to the bearing surfaces ( 3 ); free-lying legs ( 5 ) extending between respective bearing surfaces ( 3 ) and the top surfaces ( 4 ); and at least one through-opening ( 10, 11, 12, 13, 14, 15, 16, 17 ) formed in at least one of free-lying top surfaces and legs.

What is claimed is:  
     
         1 . A connection element formed of a strip of a corrugated sheet, comprising a plurality of bearing surfaces (3) spaced from each other and located in a common plane; at least one attachment opening (6, 7) formed in at least one bearing surface (3); a plurality of free-lying top surfaces (4) extending parallel to the bearing surfaces (3); free-lying legs (5) extending between respective bearing surfaces (3) and the top surfaces (4); and at least one through-opening (10, 11, 12, 13, 14, 15, 16, 17) formed in at least one of free-lying top surfaces and legs.  
     
     
         2 . A connection element according to    claim 1   , wherein at least one through-opening (10, 11, 12, 13, 14, 15, 16, 17) is formed in each of several free-lying top surfaces and legs.  
     
     
         3 . A connection element according to    claim 2   , wherein at least one through-opening (10, 11, 12, 13, 14, 15, 16, 17) is formed in each of the free-lying top surfaces (4) and legs (5).  
     
     
         4 . A connection element according to    claim 3   , wherein an entire cross-section of through-openings (10, 11, 12, 13, 14, 15) formed in the legs (5) at most amounts to 75% of an entire surface of the legs (5).  
     
     
         5 . A connection element according to    claim 1   , wherein a width (B2) of a web defined by an outer surface (18) of the connection element-forming strip (1) and an inner wall of the at least one opening (10, 11, 12, 13, 14, 15) and is measured in a direction parallel to the bearing surface 3 and perpendicular to a longitudinal extent of the strip (1) corresponds at least to 0.05÷0.3 of a width (B1) of the strip (1).  
     
     
         6 . A connection element according to    claim 1   , wherein the connection element-forming strip (1) has a thickness which amounts from 0.75 mm to 3 mm.  
     
     
         7 . A connection element according to    claim 1   , wherein the connection element-forming strip (1) has a smooth outer surface.
