DEVICE FOR RELEASING TENSIONING FORCE OF TENDON, AND CONSTRUCTION METHOD FOR RELEASING TENSIONING FORCE OF TENDON BY USING IT |
摘要 |
PROBLEM TO BE SOLVED: To provide a device for releasing a tensioning force of a tendon, which enables a wedge connection between a wedge and a wedge retainer to be surely released without reference to the constitution of the tendon, and a construction method for releasing the tensioning force of the tendon. SOLUTION: This device comprises: the wedge retainer 8 for bearing reaction of a tensioning force introduction device 1 for introducing the tensioning force into the tendon 3; the wedge 9 into which the tendon 3 is inserted, and which is engaged with the wedge retainer 8 in the state of integration with the tendon 3; and a reaction bearing member 6A which bears the tensioning force from the wedge 9 and inhibits the wedge 9 from moving in the direction of getting closer to the wedge retainer 8, when the tendon 3 is pulled by the tensioning force introduction device 1 and moved in the direction of isolation from the wedge retainer 8.
