Connecting profile for connecting sheet piles of a sheet pile wall

Abstract

A connecting profile for connecting sheet piles of a sheet pile wall includes a substantially straight central strip, and a first, second and third hook strip, extending from the central strip, wherein the first, second and third hook strip include each a curved section and a substantially straight end section extending from the curved section and forming a free end of the hook strip.

         2 . A connecting profile according to  claim 1 ,
 wherein the first hook strip extends from the central strip approximately perpendicular to a longitudinal axis of the central strip.   
     
     
         3 . A connecting profile according to  claim 2 ,
 wherein the first hook strip includes a substantially straight, intermediate transition section extending approximately perpendicular to the longitudinal axis of the central strip.   
     
     
         4 . A connecting profile according  claim 1 ,
 wherein each of the hook strips is attached directly to the central strip,   without a straight intermediate transition section between the central strip and the respective hook strip.   
     
     
         5 . A connecting profile according to  claim 2  ,
 wherein the first hook strip includes a material accumulation at a side of the of the first hook strip facing the curved section of the second hook strip. 
 
     
     
         6 . A connecting profile according to  claim 1 ,
 wherein the second and third hook strip extend from the central strip, and   wherein the second hook strip is a mirror image of the third hook strip,   mirrored along a longitudinal axis of the central strip.   
     
     
         7 . A connecting profile according to  claim 6 ,
 wherein an angle in the range from 60° to 80° is formed between the longitudinal axis of the central strip and a longitudinal axis of the end section of the second and third hook strip.   
     
     
         8 . A connecting profile according to  claim 6 ,
 wherein an angle of approximately  70 ° is formed between the longitudinal axis of the central strip and a longitudinal axis of the end section of the second and third hook strip.   
     
     
         9 . A connecting profile according to  claim 1 ,
 wherein the second and third hook strip extend from the central strip, and   wherein the second hook strip is a mirror image of the third hook strip mirrored along a longitudinal axis of the central strip and mirrored along an axis perpendicular to the longitudinal axis of the central strip.   
     
     
         10 . A connecting profile according to  claim 1 ,
 wherein the third hook strip comprises a substantially straight, intermediate transition section extending approximately perpendicular to a longitudinal axis of the central strip, and   wherein the curved section of the third hook strip extends from the transition section.   
     
     
         11 . A connecting profile according to  claim 10 ,
 wherein the first and third hook strip extend from a first end of the central strip, and   wherein the second hook strip extends from a second end of the central strip.   
     
     
         12 . A connecting profile according to  claim 10 ,
 wherein the free ends of the first and/or third hook strip point toward the transition section, and/or   wherein the free end of the second hook strip points substantially toward the central strip.   
     
     
         13 . A connecting profile according to  claim 10 ,
 wherein an angle in the range from 60° to 80° is formed between a longitudinal axis of the transition section of the third hook strip and a longitudinal axis of the end section of the third hook strip.   
     
     
         14 . A connecting profile according to  claim 10 ,
 wherein an angle of approximately 70° is formed between a longitudinal axis of the transition section of the third hook strip and a longitudinal axis of the end section of the third hook strip.   
     
     
         15 . A connecting profile according to  claim 1 ,
 wherein the curved section of the first, second and/or third hook strip have semicircular shape.   
     
     
         16 . A connecting profile according to  claim 15 ,
 wherein the free end of the second and/or third hook strip points toward the central strip.   
     
     
         17 . A connecting profile according to  claim 1 ,
 wherein an angle in the range from 50° to 70° is formed between a longitudinal axis of the end section of the first hook strip and a longitudinal axis of the central strip.   
     
     
         18 . A connecting profile according to  claim 1 ,
 wherein an angle of approximately  60 ° is formed between a longitudinal axis of the end section of the first hook strip and a longitudinal axis of the central strip.
