Peeling prevention structure for concrete structures

摘要

PROBLEM TO BE SOLVED: To provide an exfoliation prevention structure of a concrete structure which can be constructed at low cost and easily by reducing work steps and shortening construction time, in which progress of deterioration in the concrete structure can be clearly observed after construction or exfoliation of concrete can be easily recognized visually so as to secure safety of the concrete structure.;SOLUTION: In an exfoliation prevention structure of a concrete structure, a thin reinforcement sheet 6 is fixed on a surface of a concrete structure 2. The reinforcement sheet 6 is constituted in a transparent sheet-like shape in which multiple synthetic resin films are laminated to be integrated. The reinforcement sheet 6 comprises: a strong core film 8; an extremely thin easy adhesion layer 9 which is fixed to at least one side of the core film 8 and which is easy to adhere; and a thin-film weather-resistant layer which is fixed to the easy adhesion layer 9, which can be peeled from an adhesion layer 7 by displacing by a fixed amount or greater at predetermined loading time and which has weather resistance.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2019,JPO&INPIT
