| description | PROBLEM TO BE SOLVED: To effectively repair and reinforce a structure and a member of concrete construction using a fiber strand. SOLUTION: The long and flexible fiber strand 2 formed by bundling high strength reinforcing fiber such as carbon fiber is wound around an object for repair and reinforcement and fixed with resin. The fiber strand is previously impregnated with resin in the unhardened state, and the resin is hardened by operation from the outside after winding. A beveling adjusting material formed of material with strength not less than the strength of the object is mounted to the object to form a curved surface at a corner part, and the fiber strand is wound on the outside of the beveling adjusting material. Thermosetting resin is used as the resin, and the resin is hardened being heated by a heater 3 or heated by applying a current to the fiber strand by a power unit 4 to generate heat. Or photo-curable resin is used as the resin, and the resin is hardened by the irradiation of light from the outside by a light projecting means such as a light projector 5. |
