Stranded cable wedge

Abstract

A split wedge body, which has a curved inner surface, is formed gradually thicker from a tip portion to a terminal end portion thereof, and is made to cover the outer peripheral surface of a CFRP cable to thereby enclose the outer peripheral surface of the CFRP cable over a prescribed length thereof. A gap extending in the longitudinal direction is assured between end faces that oppose each other when a plurality of the split wedge bodies are arranged on the outer peripheral surface of the CFRP cable. The gap has an inclined portion that runs along a valley of the CFRP cable enclosed by the split wedge bodies.

What is claimed is: 
     
         1 . A stranded cable wedge comprising a plurality of split wedge bodies, each of which has a curved inner surface and is formed gradually thicker from a tip portion to a terminal end portion thereof, made to cover the outer peripheral surface of a stranded cable to thereby enclose the outer peripheral surface of the stranded cable over a prescribed length thereof;
 characterized in that a gap, which is assured between end faces that oppose each other when said plurality of split wedge bodies are arranged on the outer peripheral surface of the stranded cable, has a valley following gap portion that runs along a valley of the stranded cable enclosed by said split wedge bodies.   
     
     
         2 . A stranded cable wedge according to  claim 1 , wherein the gap assured between the opposing end faces includes a valley following gap portion that runs along a valley of the stranded cable and a valley non-following gap portion that does not run along a valley of the stranded cable; a plurality of said valley following gap portions being formed in the longitudinal direction bracketing the valley non-following gap portions between them. 
     
     
         3 . A stranded cable wedge according to  claim 2 , wherein length of said valley following gap portion is greater than length of said valley non-following gap portion. 
     
     
         4 . A stranded cable wedge according to  claim 2 , wherein direction of said valley following gap portion and direction of said valley non-following gap portion intersect within a range of 75° to 120°. 
     
     
         5 . A stranded cable wedge according to  claim 1 , wherein said curved inner surface is formed to have a plurality of grooves formed along the strands constituting the stranded cable and each having a size conforming to the diameter of the strand constituting the stranded cable. 
     
     
         6 . A stranded cable wedge according to  claim 1 , wherein engaging portion for alignment is formed on each of the plurality of split wedge bodies. 
     
     
         7 . A stranded cable wedge formed gradually thicker from a tip portion to a terminal end portion thereof and having a curved inner surface that comes into contact with a stranded cable, said wedge enclosing the outer peripheral surface of the stranded cable over a prescribed length thereof by being arranged around the stranded cable leaving a gap in the longitudinal direction;
 wherein an end face of a side wall on both sides of the curved surface of one stranded cable wedge and an end face of a side wall on both sides of the curved surface of another stranded cable wedge adjacent to said one stranded cable wedge, which end faces form the gap, are formed with an inclination that runs along a valley of the enclosed stranded cable.   
     
     
         8 . A stranded cable wedge according to  claim 7 , wherein the end face of both side walls includes a gently sloping surface that runs along a valley of the stranded cable, and a sharply sloping surface that does not run along a valley of the stranded cable; a plurality of said gently sloping surfaces being formed in the longitudinal direction bracketing the sharply sloping surfaces. 
     
     
         9 . A stranded cable wedge according to  claim 8 , wherein length of said gently sloping surface is greater than length of said sharply sloping surface. 
     
     
         10 . A stranded cable wedge according to  claim 8 , wherein direction of said gently sloping surface and direction of said sharply sloping surface intersect within a range of 75° to 120°.
