SHEARING REINFORCING THERMOPLASTIC RESIN COATED FRP ROD

摘要

PROBLEM TO BE SOLVED: To provide a shearing reinforcing rod excellent in the adhesion capacity with concrete, having necessary physical properties as the shearing reinforcing rod such as tensile strength or the like and good in productivity. SOLUTION: One FRP strand A being a reinforcing fiber bundle F impregnated with a thermosetting resin 13 and externally coated with a thermoplastic resin 14 is used as a core strand 11 and six strands 12 are spirally intertwisted on the outer peripheral of the core strand 11 to form an FRP rope 10 or eight FRP strands A are braided in an eight strand plaited rope shape to form an eight strand plaited FRP rope 50. The FRP rope 10 or 50 is molded into a rectangular spiral shape so that the radius of each of corner parts R becomes 3-5 times the outer diameter of the FRP rope 10 or 50 to obtain a shearing reinforcing rod 20.
