Glass fiber reinforced plastic engineering anchor rod and manufacturing method thereof

Abstract

The invention relates to the field of engineering building materials, belongs to the category of new materials, and in particular relates to a glass fiber reinforced plastic (FRP) engineering anchor rod and a manufacturing method thereof. The invention is characterized in that: raw materials mainly comprise glass fibers, resins and additives, wherein the glass fibers account for 70 to 85 weight percent of the raw materials. The invention has the advantages that: the FRP material has the advantages of light weight, high strength, corrosion resistance, capacity of being easily cut, insulativity (not conducting electricity or magnetism), flame retardancy, low-temperature resistance, fatigue resistance and the like; the anchor rod can locally replace steel bars according to the characteristics of the FRP material so as to fulfill the aim of saving steel and labor cost, the labor efficiency can be greatly improved, and the cost is saved; the anchor rod can be applied to environments with serious corrosion of corrosive media for a long time, can maintain the strength and service life, and meet the requirement of structure durability; the anchor rod can be applied to structure with special requirements; and prestress loss due to concrete creep and shrinkage can be reduced, and the prestress loss due to prestressed reinforcing steel loosening can be reduced.

Description

technical field [0001] The invention relates to the field of engineering building materials and belongs to the category of new materials, in particular to a glass fiber reinforced plastic engineering anchor rod and a manufacturing method thereof. Background technique [0002] For a long time, steel is the first choice for making anchor rods, and problems such as steel corrosion have increasingly become prominent problems affecting the safety and durability of anchoring systems, especially in some severely corrosive mountainous areas, as well as soft soil areas with rich groundwater and In the construction of high-speed rail projects, the corrosion problem of steel is more serious. The traditional way to solve this kind of problem is to spray anti-corrosion agent on the surface of the steel, or change the physical and chemical composition of the steel to improve the corrosion resistance of the steel, but this method will increase the complexity of the bolt installation operat...
