Embodiment Construction

[0037] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0038] This embodiment provides a reinforced concrete reinforcement method based on CFRP, which is mainly used to solve the problem that the existing beam 1 and column 2 cannot be reinforced by pasting continuous carbon fiber cloth 11 at the inner knuckle; it is also applicable to other Building components with chamfers.

[0039] Taking the connection between column 2 and beam 1 as an example, the construction method is explained in detail:

[0040] 1. Construction preparation: prepare the tools, materials, equipment and prefabricated components 3 needed in the relevant construction process; the prefabricated components 3 are concrete components, such as figure 1 It includes two mutually perpendicular structural plates 4, the angle between the two structural plates 4 is an arc-shaped transition surface 5, and the outside of the two structural plates 4 is a p...

Abstract

The invention discloses a reinforced concrete reinforcement method based on CFRP. The reinforced concrete reinforcement method mainly comprises the following steps that 1, a prefabricated member is customized; 2, two planes, forming break angles, of a building member are leveled; 3, clamping grooves used for allowing the prefabricated member to be embedded are formed in the positions, close to thebreak angles, of the two planes in a chiseled mode; 4, the clamping grooves are internally filled with structural adhesives, and the prefabricated member is embedded into the clamping grooves; 5, theprefabricated member is subjected to anchorage measures; 6, bottom layer resin is smeared and cured and then forms a smooth surface; 7, bonding resin is smeared, and a carbon fiber cloth is pasted; 8, the carbon fiber cloth at the transition face is subjected to compressing measures; 9, an inclined strut is arranged between the two vertical planes of the building member for compressing the carbonfiber cloth; and 10, the carbon fiber cloth is coated with a fire-resistant coating. The problem that the inner break angle positions of the building member with the inner break angles are difficultto paste and reinforce through the continuous carbon fiber cloth is solved.

Description

technical field [0001] The invention relates to the technical field of building reinforcement, in particular to a reinforcement method for reinforced concrete based on CFRP. Background technique [0002] In recent years, more and more bridges and buildings need to be reinforced. Common reinforcement methods include enlarging section method, bonded steel reinforcement method, and bonded carbon fiber cloth reinforcement method. Advantages such as increasing the self-weight of buildings have been widely used in recent years. [0003] However, although carbon fiber cloth has the advantages of high strength and light weight, it also has certain shortcomings. The reinforcement effect of carbon fiber cloth is largely determined by the material of carbon fiber cloth and the quality of the binder. Common failure problems of carbon fiber cloth are caused by carbon fiber cloth. caused by peeling. Therefore, when constructing building components with outer knuckles such as columns and...
