REPAIR METHOD USING PHOTO-CURING FIBER-REINFORCED RESIN SHEET FOR CONCRETE CONSTRUCTION

摘要

PROBLEM TO BE SOLVED: To provide a method to repair and reinforce a concrete construction by applying a photo-curing fiber-reinforced resin sheet which cures and adheres upon receipt of ultraviolet rays on a surface of a repair-required part of the concrete construction so as to be cured and adhered by the ultraviolet rays.

SOLUTION: The photo-curing fiber-reinforced resin sheet 1 applied on the surface of a repair-required part of the concrete construction 3 is heated up to a plasticized temperature until it is softened enough to be plasticized. A pressure is given to the sheet 1 to be firmly attached to the concrete surface 10. Then the sheet 1 is irradiated by the ultraviolet rays to be cured and is adhered onto the concrete surface 10 for a repair and reinforcement.
