PROBLEM TO BE SOLVED: To provide a reinforcing method which improves workability of conventional reinforcing method and reduces construction period and further, brings out a stable reinforcing effect for a long time. SOLUTION: After a reinforcing sheet 10 in which conductive tapes or condactors are woven as warp threads 3 into an unidirectional sheet whose warp threads 1 are substantially made of Aramid or a reinforcing sheet 10 in which conductive tapes or conductors are further woven as the weft into the reinforcing sheet 10 has been wound around a structure, a thermosetting resin is applied on the reinforcing sheet 10 so that the sheet is impregnated with the resin and then, electric currents are sent to the conductive tapes or conductors to heat them and also heat the thermosetting resin and cure it in order to reinforce the structure. In this reinforcing method, the thermosetting resin is hardened in at least two-stage heating. |
