Method for reinforcing capping beam by using carbon fiber and reinforcing structure

Abstract

The invention discloses a method for reinforcing a capping beam by using carbon fiber and a reinforcing structure, which are used for solving the problem that the reinforcement is not firm. The methodcomprises the following steps: step 1, carrying out construction lofting and measurement on the capping beam to be reinforced, accurately determining the size of a repaired steel piece, preparing therepaired steel piece, and fixing the repaired steel piece at a chamfer of the capping beam; step 2, at least arranging one carbon fiber board, a set of fixed end support components, a tension end support component and a closed reinforcing ring consisting of connecting steel plates at the positions of the upper edge or / and the lower edge of the capping beam; step 3, treating the area between the two carbon fiber boards by using carbon fiber cloth. The method for reinforcing the capping beam by using carbon fiber and the reinforcing structure have sufficient self-locking property and floating property, ensures that a closed ring is formed between the carbon fiber board, the support component and the connecting steel piece through the connecting steel plate, and a pre-stress is formed between the closed rings to reinforce the capping beam, thereby having better reinforcing effect than the traditional reinforcing effect.

Description

technical field [0001] The invention relates to the technical field of bridge reinforcement. Background technique [0002] According to Baidu Encyclopedia: Bridge reinforcement is to improve the bearing capacity and service performance of components and even the entire structure through certain measures to meet new requirements. That is to say, it is necessary to deal with the situation that the bridge cannot meet the continuous use. [0003] Reasons for strengthening include poor durability and aging of the bridge, poor design or poor construction quality, etc. After the bridge is reinforced, the service life of the bridge can be extended, and with a small amount of capital investment, the bridge can meet the demand of traffic volume, and it can also ease the concentration of bridge investment, prevent and avoid the loss of people and property caused by bridge collapse. [0004] Cover beam 000 is a beam set on the top of bent pile piers to support, distribute and transmit...
