CRACK CONTROL STRUCTURE FOR CONCRETE BODY

摘要

PROBLEM TO BE SOLVED: To provide a crack control structure for a concrete body, which ensures armoring of coating member at the predetermined position of a reinforcement while the reinforcement armored by the coating member is not decomposed.;SOLUTION: In the crack control structure for a concrete body, a crack inducing joint is formed on a surface of the concrete body in which the reinforcements are embedded, while the coating member 5 for preventing attachment of concrete to an intersecting part 3a of the reinforcement 3 which three-dimensionally crosses with the crack inducing joint. The coating member 5 includes an adhesive layer 7 for attaching to the surface of the reinforcement, a base layer 8 composing of a foamed body and a coating layer 9 composing of decomposable substance having at least either one of the characteristics of hydrolytic decomposition or alkali decomposition.;COPYRIGHT: (C)2006,JPO&NCIPI
