Japanese Patent JP6886756
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide, for reinforcing a concrete structure with embedded reinforcing bars, a reinforcement material for civil engineering and construction having excellent fixing property inside the structure.SOLUTION: Multiple protrusions 3 are formed by integrating reinforcing fibers, preferably GFRP reinforcing fibers with an appropriate thickness on the outer peripheral surface of a CFRP-made reinforcement material body 2 to constitute a reinforcement material 1. The reinforcement material 1 comprises a carbon fiber reinforced resin material or an aramid fiber reinforced resin material. The protrusion 3 comprises at least one kind of material selected from a group of glass fiber reinforced resin material, carbon fiber reinforced resin material, polyamide fiber reinforced resin material, polyester fiber reinforced resin material, and vinylon fiber reinforced resin material.SELECTED DRAWING: Figure 1
