Construction method and construction system for FRP reinforcement

Abstract

The invention discloses a construction method and system for FRP reinforcement. The construction method comprises the following steps that S1, a to-be-reinforced area of a bridge or building structureis positioned; S2, slide rails are fixedly mounted on the two sides of the to-be-reinforced area; S3, a construction instrument is fixed to an operation platform, and the operation platform is installed on the sliding rails; S4, the operation platform is moved on the sliding rails so that the construction instrument carries out construction work in the to-be-reinforced area along the sliding rails; and S5, after the construction work of the to-be-reinforced area is completed, the operation platform and the sliding rails are disassembled in sequence. The operation platform is installed on thesliding rails, when the operation platform is pushed to move along the sliding rails, the construction instrument can work along the to-be-reinforced area, all construction procedures of FRP reinforcement are completed, and the labor intensity of erecting a beam bottom scaffold construction platform and all the reinforcement procedures is reduced through construction; and as an operation path is clear, each process can be carried out at a designed position, a construction direction is completely controllable, and a construction error can be reduced.

Description

technical field [0001] The invention belongs to the technical field of bridge reinforcement, in particular to a construction method and a construction system for FRP reinforcement. Background technique [0002] In the field of bridge reinforcement, Fiber Reinforced Polymer (FRP) has excellent properties such as light weight, high strength, corrosion resistance and fatigue resistance, and has been widely used in the reinforcement and new construction of bridges and buildings and other engineering structures. To improve the utilization rate of FRP material strength, prestress is often applied to FRP material. Common prestressed FRP reinforcement methods include surface paste (external paste) and surface embedding (embedded). In the external reinforcement method, the concrete protection layer at the bottom of the beam needs to be polished until the aggregate is exposed before reinforcement to provide Better bonding effect; while in the embedded reinforcement method, it is nece...
