PROBLEM TO BE SOLVED: To provide legged support reinforcement for post-fitting of a support in a concrete structure which can be fixed, with the length of a screw bolt as the leg adjusted arbitrarily in conformity with the depth of a hole of the structure, and of which the screw bolt can be made to be of a small diameter. ;SOLUTION: In legged tubular support reinforcement P which is fixed by casting of hardening resin with the leg put in a hole bored in a concrete structure, a tubular long nut 3 is fitted in the lower end part of the support reinforcement P and fixed and a screw bolt with a short piece nut 7 is screwed therein as the leg. Even when the hole 13 bored in the structure for insertion of the screw bolt 5 as the leg is shallow due to the hindrance of a reinforcing bar, the legged support reinforcement P can meet the hole easily, since it can be fixed with the length of the leg adjusted arbitrarily. Besides, the operability is very excellent, since the hole 13 can be made such a small bored hole as simplifies execution of work, while allowing the screw bolt 5 to be held therein. Moreover, the important part of a support 1 can be reinforced rationally to prevent it from being broken, and the strength of the structure can be maintained by the reinforcing bar.;COPYRIGHT: (C)2000,JPO
