  • Reinforcing method and reinforcing structure for steel structure and elastic layer forming material for reinforcing steel structure
    Patent number: 9682535
    Abstract: A reinforcing method and structure for a steel structure and an elastic layer forming material for reinforcing a steel structure are provided that can prevent a reinforcing effect from being lowered by direct sunlight, can obtain a sufficient reinforcing effect, and can prevent a fiber sheet from being peeled away from a steel structure surface before the fiber sheet is torn. The reinforcing method for a steel structure, in which a fiber sheet including reinforcing fibers is bonded to a surface of the steel structure to integrate the fiber sheet with the steel structure, includes (a) a step of applying and hardening a polyurea resin putty to the surface of the steel structure to form an elastic layer, and (b) a step of bonding the fiber sheet to the surface of the steel structure having the elastic layer formed thereon with an adhesive agent.
    Type: Grant
