PURPOSE:To efficiently reinforce a structure by sticking a plate bode impregnated with resin into reinforcing fibers and the like on the surface of a structure element to be reinforced of a structure, coating a solution containing a hardening agent and a solvent, and drying and hardening it. CONSTITUTION:Resin such as phenol resin and epoxy resin serving as a matrix is impregnated into a uniaxial orientation object, a woven fabric, and a nonwoven fabric of fibers such as carbon fibers and glass fibers used as reinforcing fibers to form a plate shape with the thickness of about 0.1-2mm. This plate body is stuck on the surface of a structure element to be reinforced of a structure, a solution containing a hardening agent such as hexamethylenetetramine and aliphatic diamine and a solvent such as ethanol is coated, and it is dried and hardened by forced hot-air drying and the like. The solution is hardened in a short time with good workability regardless of the change of temperature, and the structure can be efficiently reinforced. |
