Reinforcement element for structural concrete construction

Abstract

A reinforcing element ( 10 ) for structural concrete construction comprising a rod-shaped bar ( 11 ) having a cross-sectional enlargement on at least one end thereof. The rod shaped member ( 11 ) comprises an elbow portion ( 12 ) on said at least one end being embedded in a protection block ( 15 ), thereby forming said enlargement. The method for producing the reinforcing element and the corresponding reinforced structural concrete construction are also provided.

1 . A reinforcing element ( 10 ) for structural concrete construction, in particular for reinforced or prestressed concrete construction, comprising:
 a rod-shaped bar ( 11 ) having a cross-sectional enlargement on at least one end thereof;   wherein said rod shaped bar ( 11 ) comprises an elbow portion ( 12 ) on said at least one end;   said elbow portion ( 12 ) being embedded in a protection block ( 15 ), thereby forming said enlargement.   
     
     
         2 . The reinforcing element of  claim 1 , wherein the protection block ( 15 ) material is concrete and preferably high or ultra high performance concrete. 
     
     
         3 . The reinforcing element of  claim 1 , wherein the protection block ( 15 ) material is selected from the list comprising ceramic and resin. 
     
     
         4 . A reinforcing element according to  claim 1 , wherein the protection block ( 15 ) material is reinforced with fibers. 
     
     
         5 . A reinforcing element according to  claim 1 , wherein the protection block ( 15 ) is disk-shaped. 
     
     
         6 . A reinforcing element according to  claim 1 , wherein the protection block ( 15 ) material is substantially impermeable. 
     
     
         7 . A reinforcing element according to  claim 1 , wherein the protection block ( 15 ) material provides high adhesion to said rod-shaped bar ( 11 ). 
     
     
         8 . A reinforcing element according to  claim 1 , comprising two protection blocks ( 15 ), one at each end thereof. 
     
     
         9 . A reinforcing element according to  claim 1 , wherein the rod-shaped bar ( 11 ) is U-shaped with a connecting leg ( 17 ) provided between the two axial portions ( 16 ) and further comprises a protection block ( 15 ) in which said connecting leg ( 17 ) is at least partially embedded. 
     
     
         10 . A reinforcing element according to  claim 1 , further provided with a protection channel ( 20 ) provided on one axial portion ( 16 ) of the rod-shaped bar ( 11 ), at the immediate proximity of said protection block ( 15 ). 
     
     
         11 . A reinforcing element according to  claim 1 , wherein the elbow portion ( 12 ) comprises an angled portion ( 13 ) and a radial member ( 14 ) extending substantially radially from adjacent axial portion ( 16 ). 
     
     
         12 . A reinforcing element according to  claim 11 , wherein the angle (α) between radial member ( 14 ) and adjacent axial portion ( 16 ) is substantially 90 degrees. 
     
     
         13 . A method for producing a reinforcing element ( 10 ) for structural concrete construction in the form of a rod shaped bar ( 11 ) provided with a protection block ( 15 ) at one end thereof, comprising:
 producing said rod-shaped bar ( 11 );   bending end portion of said rod bar;   covering said bent portion with a protection block ( 15 ).   
     
     
         14 . A reinforced structural concrete construction, comprising:
 a concrete volume to be reinforced;   a rod-shaped bar ( 11 ) comprising an elbow portion ( 12 ) on said at least one end, said elbow portion ( 12 ) being embedded in a protection block ( 15 );   said rod-shaped bar ( 11 ) being at least partially embedded in said concrete volume according to a given reinforcing position in which said protection block is also at least partially embedded in said concrete volume in order to provide said reinforced concrete construction.   
     
     
         15 . A reinforced structural concrete construction according to  claim 14 , wherein said protection block is fully embedded in said concrete volume.
