Peeling prevention material and peeling prevention structure for concrete structures

摘要

PROBLEM TO BE SOLVED: To provide a peeling prevention material and a peeling prevention structure of a concrete structure which can be surely fixed to a concrete surface even though it has a simple structure and can be connected without requiring end treatment while having a water conducting function. SOLUTION: A peeling prevention material 1 is provided on a drainage sheet 10 having a sheet body 11 and a plurality of water guiding reinforcing ribs 12 projecting along the longitudinal direction of the back surface of the sheet body 11, and on the front surface of the sheet body 11. It is characterized by including a lattice material 20 arranged along the line. In the peeling prevention structure, the back surface faces the concrete surface of the concrete structure, the peeling prevention material 1 is arranged along the concrete surface, a plurality of fixing members arranged on the front surface of the lattice material 20, and the tip is inside the concrete structure. The peeling prevention material 1 is provided with a plurality of anchor materials in which the head protrudes from the concrete surface and communicates the peeling prevention material 1 and the fixing member, and the peeling prevention material 1 is concreted through the bearing pressure of the lattice material 20 by the fixing member. It is characterized by being fixed to a surface. [Selection diagram] Fig. 1
