PROBLEM TO BE SOLVED: To prevent net bodies and coating resin for reinforcement from exfoliating off the surface of concrete structure, during the construction work of concrete structure. SOLUTION: In this reinforcement method, grooves 11 in which lattice bars 20 for reinforcement are fitted are formed on the surface of a slab 1 of a concrete bridge. The lattice bars 20 are fitted into and fixed securely to the grooves 11, and a reinforcement layer is fixedly cut into the slab 1, even when an existing bridge which is installed warps, while the lattice bar 20 follows displacement of this bridge, and effects tensile stress, forming no gap between the reinforcement layer and the concrete, so that the lattice bar 20 and the existing bridge are unified. Therefore the surface exfoliation can be prevented for a long period of time. COPYRIGHT: (C)2004,JPO
