PROBLEM TO BE SOLVED: To solve the problem in applying wedge anchoring when a wire for tension-connecting a connected member is extremely short, wherein a jack is conventionally repositioned and repetition of set amount correction work is required until the convergence of the set amount, and this work is complicated and requires hard labor and affects more as the wire is shorter, which makes appropriate tension management and introduction of uniform prestress difficult in some cases. SOLUTION: A sleeve 3 is fixed by a wedge 7 to the tension end 6 of the wire passing through two or more connected members to be connected, and its grip is pulled to sink the wedge into the sleeve. The wire is also pulled while generating the set amount, and the set amount is corrected by a ring nut 5 screw-fitted to the sleeve, thus anchoring the wire. COPYRIGHT: (C)2007,JPO&INPIT
