Abstract

The present invention relates to method of reinforcing concrete structure with top pushed pre-stressed carbon fiber cloth and its application. The method includes the following steps: fixing one end of the carbon fiber cloth to the concrete structure and adhering the other end to anchor plate and fixing to the pushing board to form the stretching end; brushing special glue to the surface of concrete structure, controlling the interval between the stretching end and the concrete structure with the limiting board, and pushing the stretching end forward with the pushing device the stretch the carbon fiber cloth; reaching the stress and regulating the limiting board to make the stretching end adhering the surface of the concrete structure; and disassembling the pushing device, the limiting board and the pushing board after curing. The present invention can reach excellent reinforcing effect.

Description

[technical field]

[0001] The invention relates to the technical field of reinforcing concrete structures with fiber composite materials, in particular to a method and application of carbon fiber cloth reinforcing concrete structures. [Background technique]

[0002] Carbon fiber cloth reinforced concrete structure is a technology that has only gradually developed in China in recent years. The production technology of domestic carbon fiber raw materials is not yet qualified. Almost all carbon fiber precursors used for engineering reinforcement rely on imports. Due to the restrictions of importing countries, The price of imported raw silk has risen sharply. Fiber composite materials have the advantages of high strength, light weight, strong weather resistance, convenient construction, and almost no increase in component cross-section. Composite fiber cloth has become an ideal reinforcement material, so the annual import of raw silk has also doubled. At present, the constructio...
