PROBLEM TO BE SOLVED: To provide a reinforcement tool for a concrete structure for easily, quickly and inexpensively executing reinforcement work, by preventing the concrete structure itself from being damaged, by restraining the expansion of a crack caused in the concrete structure.SOLUTION: A reinforcement tool 1 for a concrete structure is composed by integrally molding a pair of inserting shaft parts 2 and a bridge shaft part 5 by mortar. The inserting shaft parts 2 inserted into an insertion hole 22 of the concrete structure 21, are formed in a columnar shape, and form a plurality of annular locking grooves 3 of a cross-sectional substantially U shape by separating in the axial direction. The respective annular locking grooves 3 communicate by a mortar introduction groove 4. The bridge shaft part 5 of crossing the crack 23 of the concrete structure 21 is formed in a columnar shape, and both ends in the axial direction are linked to the inserting shaft parts 2. |
