CONCRETE STRUCTURE AND REINFORCING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a reinforcing method for a concrete structure capable of easily executing the structure in a short-time construction and obtaining high strength. SOLUTION: The surface of a part to be reinforced of the concrete structure is cleaned by polishing or the like. Braided cloth is stuck to the surface of the concrete structure. As the braided cloth, fiber groups having the plural fiber bundles, the axial directions of which are arranged in parallel in one direction through designated spaces are integrally laminated without interweaving the fiber bundles. The axial directions of the fiber bundles of the braid cloth are three axes or four axes. The stuck braid cloth is impregnated with liquid thermosetting resin at a normal temperature, hardened by degassing, and integrally fitted to accomplish reinforcement. There is no polarity of strength of the braid cloth against the tensile force. Load applied to the concrete structure can be surely absorbed with uniform strength to reinforce the concrete structure with high strength. Execution can be easily performed in a short time.
