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. The first second, and third hook strips each include a curved section and a substantially straight end section extending from the curved section and forming a free end of the hook strip.

What is claimed is: 
     
         1 . A connecting profile for connecting sheet piles of a sheet pile wall, comprising:
 a substantially straight, elongate central strip having a first end and a second end;   a first hook strip extending from the first end of the central strip, wherein the first hook strip includes a curved section and a substantially straight free end extending from the curved section;   a second hook strip extending from the second end of the central strip, wherein the second hook strip includes a curved section and a substantially straight free end extending from the curved section; and   a third hook strip extending from the second end of the central strip, wherein the third hook strip includes a curved section and a substantially straight free end extending from the curved section.   
     
     
         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 comprises a substantially straight, intermediate transition section extending approximately perpendicular to the longitudinal axis of the central strip. 
     
     
         4 . A connecting profile according to  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 comprises a material accumulation between the curved section of the first hook strip and the central strip. 
     
     
         6 . A connecting profile according to  claim 1 , wherein the second hook strip is a substantially 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 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 1 , wherein the curved section of the first, second and third hook strips have a substantially semicircular shape. 
     
     
         12 . A connecting profile according to  claim 11 , wherein the free end of the second and/or third hook strips points toward the central strip. 
     
     
         13 . A connecting profile according to  claim 12 , wherein the free end of the first hook strip points toward the central strip. 
     
     
         14 . 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. 
     
     
         15 . 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. 
     
     
         16 . A connecting profile according to  claim 1 , wherein an angle in the range from 50° to 80° is formed between a longitudinal axis of the end section of the first, second, and/or third hook strips and a longitudinal axis of the central strip. 
     
     
         17 . A connecting profile according to  claim 1 , wherein the third hook strip extends from the second end of the central strip at a first direction, the second hook strip extends from the second end of the central strip at a second direction, and the first direction is substantially opposite to the second direction.
