STRUCTURE-REINFORCING METHOD MAKING USE OF FIBER-REINFORCED SHEET AND SHEAR KEY REINFORCED BY FIBER, FOR IMPROVING RIGIDITY AND STRENGTH OF STRUCTURE,AND STRENGTH AGAINST SHEAR OF SHEAR KEY

摘要

PURPOSE: A structure-reinforcing method making use of a fiber-reinforced sheet and a shear key reinforced by a fiber is provided to reinforce adhesion strength of a structure and fiber-reinforced sheets, to enhance strength against shear of the shear key, and to increase economical efficiency in the reinforcing work. CONSTITUTION: A structure-reinforcing method making use of a fiber-reinforced sheet and a shear key reinforced by a fiber comprises steps of successively forming plural grooves(300a,300b) at predetermined intervals in reinforcing portions of a structure(100) needing reinforcement; forming fiber-reinforced sheets(500) for shear key reinforcement, installed along the periphery and inside of the grooves and shear keys(400) formed by filling the inside of the grooves with an adhesive agent; and adhering fiber-reinforced sheets(200a,200b) on the shear keys and the fiber-reinforced sheets for shear key reinforcement.
