Additional strength manner and reinforcement structure body null of concrete

摘要

PROBLEM TO BE SOLVED: To provide a method for reinforcing a concrete structure by a reinforcing fiber-containing material and capable of preventing the peeling of the reinforcing fiber-containing material, maximally utilizing the strength of the reinforcing fiber-containing material to simply perform sufficient reinforcement, and the reinforcing fiber-containing material and a reinforced structure.;SOLUTION: The method for reinforcing the concrete structure includes a process for providing the reinforcing fiber-containing material on the surface of the concrete structure through a cushioning material of which the elongation at the time of maximum load in tension at 23°C is 10-200% and the tensile strength at 23°C is 0.1-50 N/mm2. The reinforcing fiber-containing material for reinforcing the concrete structure used in the reinforcing method contains a sheet wherein a large number of reinforcing fiber yarns are parallelly arranged. The reinforced structure for reinforcing the concrete structure is equipped with cushioning material of which the elongation at the time of maximum load in tension at 23°C is 10-200% and the tensile strength at 23°C is 0.1-50 N/mm2 and a reinforcing fiber-containing layer.;COPYRIGHT: (C)2002,JPO
