Construction process for bridge crack repairing in building construction

Abstract

The invention discloses a construction process for bridge crack repairing in building construction. The construction process for bridge crack repairing in building construction comprises the steps ofcutting carbon fiber cloth according to a size required by design, wherein before construction, the surface layer water content and the environment temperature of concrete at a bonding part should bemeasured; removing a loosened part on the surface of a reinforced member till a concrete structural layer is exposed; uniformly coating a prepared adhesive on the surface of the concrete of a part tobe bonded; laying the cut carbon fiber cloth on a base course coated with the adhesive, wherein a primer should be uniformly coated on the concrete surface, which is cleaned by acetone, by using a roller brush or a special brush; and using a special roller to roll the surface of the carbon fiber cloth in the fiber direction for multiple times. According to the construction process for bridge crackrepairing in building construction, the operation steps are simple and convenient, the close bonding of the carbon fiber cloth can be guaranteed so that the carbon fiber cloth cannot fall off in a natural environment, and the crack is repaired so that the service life and safety of a bridge can be guaranteed.

Description

technical field [0001] The invention relates to a technology, in particular to a construction technology for repairing bridge cracks in building construction. Background technique [0002] A bridge refers to a building erected on rivers, lakes and seas to enable the smooth passage of vehicles and pedestrians. It is called a bridge. A bridge is generally composed of a superstructure, a substructure, a support and ancillary structures. The superstructure is also called a bridge span structure, which is the main structure for crossing obstacles; the substructure includes abutments, piers and foundations; Or the force transmission device installed at the supporting place of the bridge abutment; the auxiliary structures refer to the bridge head board, conical slope protection, bank protection, diversion works, etc. Bridges are actually divided into three categories: girder bridges, arch bridges and suspension bridges, and cable-stayed bridges. Girder bridges are generally built...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the above-mentioned existing poor sticking effect on carbon fiber cloth, resulting in poor coverage of cracks, easy to fall off after a period of use, causing cracks to be exposed, cracks will continue to expand, and cause hidden dangers to the safety of the bridge. A construction process for repairing bridge cracks in building construction is designed. The operation steps of this process are simple and can ensure that the carbon fiber cloth is tightly pasted and will not fall off in the natural environment. The cracks are repaired to ensure the bridge's safety. The service life and safety solve the problem that the existing carbon fiber cloth is poorly pasted, resulting in poor coverage of cracks, and it is easy to fall off after a period of use, causing cracks to be exposed, and the cracks will continue to expand, causing hidden dangers to the safety of the bridge.
