Problems solved by technology

FRP bars are prefabricated materials in the factory. There is no mature technology for on-site processing and connection. They are basically connected by lap joints, which not only wastes FRP bars, but also tends to form weak layers at the overlaps of FRP bars, which affects FRP bars. Exercising high-strength performance

Abstract

The invention relates to a connector for connecting an FRP (Fiber-reinforced Plastic) rib material and a connecting method using the connector to connect the FRP rib material. The connector comprises a sleeve and a central separation plate, wherein an axial through hole is formed in the center of the sleeve, the central separation plate is arranged in the sleeve and is fixed at the center of the axial through hole of the sleeve; the side wall of the central separation plate is fixed with the inner wall of the sleeve. The FRP rib material connecting method adopts the connector and the method of injecting rib glue into the connector to complete the connection of the FRP rib material; the overlapping joint length of the FRP rib material is shortened, the waste of FRP rib material is avoided; the cost is saved; the connector can be used as being plugged; the connection is efficient and fast; the exertion of the FRP rib material strength is improved and the bonding with concrete is reliable.

Description

technical field [0001] The invention relates to a connection joint, in particular to a connection joint for connecting FRP bars; the invention also relates to a connection method, in particular to a connection method for connecting FRP bars with a connection joint. Background technique [0002] High-performance Fiber Reinforced Plastic (FRP) reinforcement is an integral reinforcement formed by impregnating high-performance continuous fibers such as carbon fiber and glass fiber in a resin with good corrosion resistance. FRP bars have the advantages of high strength, low specific gravity, corrosion resistance, and non-magnetic properties. They can be used with concrete instead of traditional steel bars, which can reduce the weight of the structure, increase the bearing capacity of the structure, and prolong the life of the structure, especially in harsh environments (high temperature, High humidity, coastal and marine structures, etc.), can better play the advantages of FRP co...
