TENSION ANCHORING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To permit the diversion of a precision-machined member to reduce cost for prestressing a concrete member or the like in tension anchoring structure for anchoring by tensioning a tension member with nonmetallic continuous fiber as main material. SOLUTION: A cylindrical member is inserted to the outside of the end of a tension member, and synthetic resin or mortar is filled to integrate the cylindrical member with the tension member 1 to form a stuck anchor body 2. The tension member 1 is inserted in a tension anchor jig 3 with an external thread cut on the outer peripheral surface, and the stuck anchor body 2 is locked to the tension anchor jig 3. A nut 4 is screwed in the tension anchor jig 3 to anchor the tension member 1 to a concrete member 10 or the like through an anchor plate 5. Tension is introduced in by screwing a tension pipe 6 to the outside of the tension anchor jig 3 and locking the other end of the tension pipe 6 to a jack 7. The tension anchor jig 3 can be a cylindrical member or a member split by an axial cutting face.
