Disjointable fixing apparatus of tension member and removal method of tension member

Abstract

The present invention relates to a tension member removable anchoring apparatus and a method of removing the tension member by separating the tension member from an anchor by using a repulsive force occurred at the time of removing tensility in order to pull out the tension member. The above features and other advantages of the present invention will make a disassembly and an installation easier.

What is claimed is:  
     
         1 . A tension member removable anchoring apparatus, comprising: 
 a trichotomized wedge support spring for preventing a regress of a trichotomized wedge in an upper portion;    a cap coupling to the trichotomized wedge support spring;    a cylinder coupled to the cap;    an anchor inserted in a central hole of the cylinder and including the trichotomized wedge binding a single line of a tension member,    a fixer made of a casting and having the tension member inserted therein; and    a coupling means for coupling the anchor and the fixer.    
     
     
         2 . (cancelled)  
     
     
         3 . The apparatus of clam  1 , wherien in the anchor, there is a punch on is a lower side of the cylinder and a stopping spring bolt preventing a return of the regressed trichotomized wedge in the punch.  
     
     
         4 . The apparatus of  claim 1 , wherein the anchor has a coupling portion coupled to the coupling measn in a lower end of the cylinder.  
     
     
         5 . The apparatus of  claim 4 , wherein the coupling means is a nipple, a socket or one-way nipple for coupling the anchor and the fixer.  
     
     
         6 . The apparatus of  claim 1 , wherein the fixer has a shape that the tension member is inserted therein and a coupling portion is coupled to the anchor when the coupling means is inserted therein.  
     
     
         7 . The apparatus of  claim 1 , wherein a single line of tension member is inserted in the fixer to cofigure the straight anchoring appratus.  
     
     
         8 . The apparatus of  claim 6 , wherein the fixer can be used separately or purally.  
     
     
         9 . A method of removing a tension member, comprising: 
 a repulsive greater than a conservative force of a trichotomized wedge support spring working on an anchor;    the trichotomized wedge support spring compressed by the repulsive force of the tension member;    the trichotomized wedge regressing to a space in a cylinder generated during compressing the spring;    a play of the trichotomized wedge becoming open;    a return of the regressed trichotomized wedge stopped by a detent of a stopping spring bolt supporting a return of the trichotomized wedge;    separating the tension member from the trichotomized wedge whose fall is stopped in a state that a play is maintained; and    removing the tension member by pulling the tension member after separating the anchor.
