Structure reinforcing method, structure-reinforcing reinforcing fiber yarn containing material, reinforcing structure material and reinforced structure

摘要

A method for reinforcing a structure with a sheet containing reinforcing fiber yarns is disclosed, by which method separation of the sheet is sufficiently prevented, maximum use of the sheet strength is achieved, and existing structures are effectively reinforced. The method includes the step of providing a sheet containing reinforcing fiber yarns over the surface of a structure selected from the group consisting of concrete and steel structures, with a flexible material interposed therebetween, the flexible material having a tensile elongation of 10 to 200% at maximum load at 23° C., and a tensile strength of 0.1 to 50 N/mm2 at 23° C.
