PROBLEM TO BE SOLVED: To provide a reinforcing structure for a concrete construction, which facilitates reinforcement against bending stress on a concrete beam while minimizing spatial constraints thereof. SOLUTION: The concrete structure is specifically a concrete bridge pier or the like, based on a rigid frame structure, including concrete columns 3, 3 and the concrete beam 2 extending between the same in one body. Each concrete column 3 has a molded member 1 having an overhanging portion 1b mounted on an upper portion thereof, and an end of the concrete beam 2 is borne by the overhanging portion 1b of the molded member 1. The molded member 1 consists of the band-like overhanging portion 1b bearing the end of the concrete beam 2, a pair of band-like mounting portions extending from both ends of the overhanging portion 1b so as to be opposed to each other, and a hunch portion 1a tapering from an intermediate portion of the overhanging portion 1b toward the mounting portion. The molded member 1 is formed of a fiber sheet containing carbon fibers or aramid fibers, or a steel plate. COPYRIGHT: (C)2006,JPO&NCIPI
