Manufacturing method of carbon fiber grid composite plate concrete continuous beam

Abstract

The invention discloses a manufacturing method of a carbon fiber mesh composite board and concrete continuous beam. A member comprises side plates, a top plate, a bottom plate, end plates, U-shaped steel hoops, a U-shaped steel hoop with a flange, and concrete, wherein the side plates, the top plate and the bottom plate are respectively made of carbon fiber mesh composite boards, and the end plates are made of common cement boards; a shear connector is embedded into the single side of the carbon fiber mesh composite board to increase the adhesion force between the concrete and the composite board; the side plates and the bottom plate are connected by the U-shaped steel hoops; the end plates are positioned at the inner end of a groove which is formed by the side plates and the bottom plate, and are clamped by G-shaped clamps; the side plates are fixed by the G-shaped clamps in each bay; the top plate is overlapped on the flange of the U-shaped steel hoop. The concrete is cast into the groove which is defined by the side plates, the top plate, the bottom plate and the end plates, and is cured, so as to form the continuous beam. The member has the advantages that no formwork is needed; the self weight is light, the durability is good, and the construction is simple.

Description

technical field [0001] The invention relates to a civil building concrete continuous beam and a manufacturing method thereof, in particular to a manufacturing method of a carbon fiber grid composite plate concrete continuous beam. Background technique [0002] With the advancement of my country's urbanization process, the application range of reinforced concrete is becoming wider and wider. However, under the long-term unfavorable natural environment and use conditions, although reinforced concrete structures can meet the strength requirements, they are damaged due to poor durability. Engineering examples abound. Due to structural cracks caused by construction, use and environment, the concrete gradually loses protection to the internal steel bars. When harmful corrosive gases enter the structure, the acidic substances combined with water will corrode the steel bars, resulting in degradation of the mechanical properties of the steel bars and damage to the performance of the c...

AI Technical Summary

Problems solved by technology

[0004] At present, there are certain problems when using carbon fiber reinforced composite materials to strengthen concrete structures. On the one hand, this material needs to be bonded to the surface of the structure by organic glue to make it final. On the other hand, carbon fiber reinforced composites are prone to peeling and damage from the surface of the structure, and the bearing capacity of carbon fiber reinforced composites cannot be fully utilized.
