Problems solved by technology

However, most of the actual concrete components are in harsh environments, especially in the coastal area, where the concrete components are seriously damaged by corrosive media, and the epoxy resin used to paste fiber reinforced composite materials is easily affected by the environment and deteriorates. As a result, the peeling failure of the bonding interface occurs, resulting in low utilization of the tensile properties of the fiber-reinforced composite material sheet, and the reinforcement effect is relatively poor
[0005] Therefore, in order to solve the problem that the existing paste reinforcement method is prone to peeling and damage at the bonded interface, a new concrete member reinforcement method and a concrete reinforcement structure are urgently needed.

Embodiment 1

[0033] like Figure 1-3 As shown, the present embodiment provides a concrete component reinforcement method, comprising the following steps:

[0034] Step 1, opening at least one groove 11 on the first surface of the concrete member 1;

[0035] Step 2, filling the first adhesive into each groove 11 and forming each first adhesive body 2;

[0036] Step 3, coating the second adhesive on the first surface and the top surface of each first bonding body 2 to form a second bonding body 3;

[0037] Step 4: Paste the fiber-reinforced composite material strip 4 on the surface of the second bonded body 3 away from the first bonded body 2 .

[0038] Therefore, the concrete member reinforcement method provided in this embodiment, such as Figure 1-3 As shown, by filling the first adhesive into the grooves 11 opened on the first surface of the concrete member 1, and coating the second adhesive on the surface of the concrete member 1 provided with each groove 11 And on the top surface o...

Embodiment 2

[0046] This embodiment provides a concrete reinforcement structure 100, such as Figure 1-3As shown, comprising a concrete member 1, a first bonding body 2, a second bonding body 3 and a fiber reinforced composite material strip 4, at least one groove 11 is opened on the first surface of the concrete member 1, and the first bonding agent It is used to fill the grooves 11 to form the first adhesive bodies 2 , and the second adhesive is used to coat the first surface of the concrete member 1 with the grooves 11 and the first adhesive bodies 2 . A second bonding body 3 is formed on the top surface, and the fiber-reinforced composite material strip 4 is used to stick on the surface of the second bonding body 3 away from the first bonding body 2 .

[0047] In the reinforcement structure of the concrete member 1 provided in this embodiment, the first adhesive is filled into the grooves 11 opened on the first surface of the concrete member 1, and the second adhesive is applied to eac...

Abstract

The invention discloses a concrete member reinforcing method and a concrete reinforcing structure, and relates to the technical field of concrete structure reinforcing, the concrete member reinforcing structure comprises a concrete member, a first bonding body, a second bonding body and a fiber reinforced composite material strip, and at least one groove is formed in the surface of the concrete member; the first binder is used for filling all the grooves to form first binding bodies, the second binder is used for coating the surface of the concrete member provided with all the grooves and the top faces of all the first binding bodies to form second binding bodies, and the fiber reinforced composite material strips are used for being pasted to the surfaces, away from the first binding bodies, of the second binding bodies; and the fiber reinforced composite material and the concrete member can be stably combined and are not easy to fall off.

Description

technical field [0001] The invention relates to the technical field of concrete structure reinforcement, in particular to a concrete member reinforcement method and a concrete reinforcement structure. Background technique [0002] With the passage of time, due to the long-term erosion of the environment and the impact of natural disasters, a large number of in-service concrete components have suffered serious damage, and the structural functions have changed, which can no longer meet the requirements of the existing codes and need to be repaired. Different degrees of repair and reinforcement. [0003] In order to strengthen the existing concrete components and improve their structural performance to meet the requirements of existing codes, a large number of new materials and technologies have been produced. Among them, fiber-reinforced composite materials are more and more popular in the concrete component reinforcement industry due to their advantages such as light weight,...
