An anchoring structure and anchoring method for a carbon fiber plate

Abstract

The invention relates to an anchoring structure and an anchoring method of a carbon fiber plate, comprising a fixing fixture, a pressing fixture and a series mechanism, the number of the fixing fixtures is three, and the three fixing fixtures are evenly arranged from left to right, and there are pressure clamps arranged in the fixing fixture. Tightening fixtures, the fixed fixtures are connected by a series mechanism, the fixed fixtures include clamping frames, connecting screws, upper pressing blocks and connecting blocks, the pressing fixtures include pressing plates, pressing blocks and pressing screws, and the anchoring methods include: The following steps: carbon fiber plate bonding, anchorage installation, prestressed tension, disassembly and secondary reinforcement. The present invention uses a plurality of fixing fixtures to anchor the carbon fiber plate in series, which can share the tensile force on the carbon fiber plate, reduce the load of the fixing fixture, improve the effective life of the anchoring structure, and use epoxy resin to double the carbon fiber plate and the anchoring structure. Reinforcement can further improve the connection strength.

Description

technical field [0001] The invention relates to the field of anchoring structures, in particular to an anchoring structure and an anchoring method of a carbon fiber plate. Background technique [0002] A considerable part of the existing buildings had problems left over from history due to the low design load standards at that time, and some buildings could not meet the requirements of the current normative use due to the change of use function, and urgently needed to be repaired and reinforced. Carbon fiber reinforcement and repair structure technology is another new type of structural reinforcement technology after enlarging the concrete section and bonding steel, including carbon fiber cloth reinforcement and carbon fiber plate reinforcement. [0003] When carbon fiber plates are used for reinforcement, the carbon fiber plates are usually anchored and stretched with a prestressed tensioning device, and finally fixed at both ends of the reinforced place. The following prob...

Problems solved by technology

[0004] (1) After the stress is relaxed, the carbon fiber plate is easy to slip between the anchorage, and the pressure on the side wall of the carbon fiber plate becomes smaller, resulting in an increase in the gap between the carbon fiber plate and the reinforced surface, making it difficult to achieve the desired effect. reinforcement effect;

[0005] (2) During the reinforcement work, the carbon fiber plate is subjected to a large tensile force. Since most of the existing anchor structures only clamp and fix the two ends of the carbon fiber plate, it is difficult to achieve a good effect of sharing the tension. After being subjected to excessive tension, it is prone to breakage, resulting in failure of reinforcement

[0006] The above unfavorable factors lead to poor anchoring performance of some existing anchorages. In order to solve the above problems, the present invention provides an anchoring structure and anchoring method for carbon fiber plates
