Abstract

The invention provides a manufacturing method for an environment-friendly fiber reinforced plastic (FRP) iron wire compound type anchor rod. The method includes the steps that unsaturated polyester resin, polyurethane, glass fibers and release agents are added into a resin adhesive fluid bath, mixed and stirred evenly; then vacuumizing defoaming is carried out; iron wire coils with the diameter being 0.4-0.6 mm and FRP are twisted through a twisting support and then rotated to form the twist degree of 10-30 degrees, and afterwards are pulled into the resin adhesive fluid bath to be impregnated; twisted and impregnated FRP iron wire composite materials continue to be pulled into a conical sleeve to be combined into a bundle and preformed; finally, the FRP iron wire composite materials combined into the bundle continue to be pulled into a hot pressing die to be subjected to die forming at the temperature of 160 DEG C-180 DEG C; a guide cap is manufactured; a wire stringing ring is machined; a fastening ring is machined; and an anchorage pier is manufactured. The defects that existing steel bar and steel strand anchor rods are easy to corrode and glass fiber reinforced plastic anchor rods are insufficient in tightening force are overcome through the environment-friendly FRP iron wire compound type anchor rod, and the environment-friendly FRP iron wire compound type anchor rod is light, high in strength, resistant to corrosion and especially suitable for construction sites where the requirement for safety performance is high.

Description

technical field [0001] The invention belongs to the technical field of building construction, and relates to a manufacturing method of a green FRP iron wire composite anchor, in particular to a manufacturing method of a green FRP iron wire composite anchor used in foundations and geotechnical engineering. Background technique [0002] FRP composite materials are high-performance materials formed by mixing fiber materials and matrix materials in a certain proportion. Due to the different types of resin used, it is called polyester FRP, epoxy FRP, and phenolic FRP. Lightweight and hard, non-conductive, high mechanical strength, less recycling, corrosion resistance. [0003] With the advancement of social science and technology, the development of civil engineering structure has benefited to a large extent from the application and development of new materials and new technologies with excellent properties. FRP, with its excellent mechanical properties and adaptability to moder...
