<P>PROBLEM TO BE SOLVED: To provide a reinforcement body and reinforcement structure of a concrete structure, capable of reinforcing the concrete structure which is difficult to reconstruct without forming a drilling hole in the concrete structure. <P>SOLUTION: A reinforcement body 2 of the concrete structure (dam body C of a dam) includes a PC cable 10, a block body 20, and a tension force transmission body 30, and a reinforcement structure 1 comprises the plurality of reinforcement bodies 2. One end 11 and the other end 12 of the PC cable 10 are both fixed to the ground G which is an immovable body. The block body 20 is arranged at the upper end part of the dam body C, and the intermediate part of the PC cable 10 is curved to be convex vertically upwards and supported. A support block (tensile force transmission body) 30 is interposed between the block body 20 and the upper end face of the dam body C, maintains the PC cable 10 in a tense state, and also transmits a part of the tension force of the PC cable 10 to the upper end face of the dam body C. <P>COPYRIGHT: (C)2012,JPO&INPIT |
