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 connection joint and a connection method for FRP reinforcements, which relate to a connection method for connecting FRP reinforcements to FRP reinforcements using connection joints. The connecting joint of the FRP bar of the present invention comprises a sleeve and a central partition plate, the center of the sleeve is provided with an axial through hole, the central partition plate is arranged in the sleeve and fixed at the center of the axial through hole of the sleeve, and the center The side wall of the dividing plate is fixed to the inner wall of the sleeve. The connection method of the FRP reinforcement of the present invention adopts the above-mentioned connection joint and injects the reinforcement glue into the connection joint to complete the connection of the FRP reinforcement, which reduces the overlapping length of the FRP reinforcement, avoids the waste of the FRP reinforcement, and saves costs , plug and play, fast and efficient connection, improved the strength of FRP bars, and more reliable bonding with concrete.

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...
