Profiled connecting element as well as a sheet pile wall with such a profiled connecting element

Abstract

The invention relates to a profiled connecting element with a constant cross-section for sheet pile wall components such as sheet piles, with a center strip ( 12 ) and two hook strips ( 20, 22 ) protruding from the two flat sides of the center strip ( 12 ) in opposite directions. The transitional sections ( 24 ) between the center strip and the hook strips transition in a curved manner into the flat sides ( 16, 18 ) of the center strip ( 12 ) and the free end sections ( 30 ) of the hook strips, together with the flat sides ( 16, 18 ) of the center strip ( 12 ), each define a jaw ( 32 ) for engaging an interlock ( 38 ) of the sheet pile wall component ( 36 ). The flat sides ( 16, 18 ) of the center strip ( 12 ) extend, beginning at the transitional sections ( 24 ), in the direction of the free end ( 34 ) of the center strip ( 12 ) at least in parts at a specified opening angle (α) toward each other such that the center strip ( 12 ) tapers off toward its free end ( 34 ) in this section. In addition, a sheet pile wall, comprised of several sheet piles, is provided, wherein at least two sheet piles are connected to each other through a profiled connecting element of the type described above.

1 . A profiled connecting element with a substantially constant cross-section for sheet pile wall components such as sheet piles, with a center strip and two hook strips protruding from the two flat sides of the center strip in opposite directions; wherein transitional sections of said hook strips transition in a curved manner into the flat sides of the center strip; wherein the free end sections of said hook strips together with the flat sides of the center strip each define a jaw for engaging the interlock of the sheet pile wall component; wherein the flat sides of the center strip, beginning at the transitional sections, extend at least in sections in the direction of the free end of the center strip at a specified opening angle (a) such that the center strip tapers off toward its free end in this section. 
     
     
         2 . A profiled connecting element as defined in  claim 1 , wherein the opening angle (α) of the two flat sides and the distance of the free ends of the hook strips to the flat sides perpendicular to the center axis (M) of the center strip is selected such that an engaged interlock of the sheet pile wall component is always supported at at least two lines in the lock chamber formed by the respective hook strip and the flat side. 
     
     
         3 . A profiled connecting element as defined in  claim 1 , wherein the specified opening angle (α) is in a range of 10 to 30°. 
     
     
         4 . A profiled connecting element as defined in  claim 3 , wherein the specified opening angle (α) is in a range of 15° to 25°. 
     
     
         5 . A profiled connecting element as defined in  claim 1 , wherein the hook strips exhibit an at least approximately constant wall thickness (d) and wherein the greatest distance (c) between the flat sides viewed perpendicular to the center axis (M) of the center strip corresponds at least to one-and-a-half times two times the wall thickness (d) of the hook strips. 
     
     
         6 . A profiled connecting element as defined in  claim 1 , wherein the identically designed hook strips protrude from the center strip running mirror symmetrical to the center axis (M). 
     
     
         7 . A profiled connecting element as defined in  claim 1 , wherein the center strip tapers off only to a common plane with the free end sections of the hook strips. 
     
     
         8 . A profiled connecting element as defined in  claim 1 , wherein the hook strips are designed identically, and wherein the transitional section of each hook strip transitions into a connection section that extends at least approximately at a right angle to the center axis (M) of the center strip and itself transitions into a curved hook section, whose free end section points in the direction of the center strip. 
     
     
         9 . A profiled connecting element as defined in  claim 7 , wherein the curved hook section covers a 180° arc. 
     
     
         10 . A profiled connecting element as defined in  claim 9 , wherein the curved hook section is semicircular. 
     
     
         11 . A profiled connecting element as defined in  claim 1 , wherein the free end of the center strip and the two end sections of the hook strips end at least approximately in a common plane perpendicular to the center axis (M) of the center strip. 
     
     
         12 . A profiled connecting element as defined in  claim 1 , wherein the end of the center strip is formed as a third hook strip. 
     
     
         13 . A profiled connecting element as defined in  claim 10 , wherein one of the flat sides of the center strip, together with the third hook strip, forms a Larssen interlock. 
     
     
         14 . A profiled connecting element as defined in  claim 1 , wherein the profiled connecting element is formed by rolling a blank. 
     
     
         15 . A sheet pile wall comprised of several sheet piles, wherein at least two sheet piles are connected to each other through a profiled connecting element as defined in  claim 1 .
