Composite shear connection piece of steel-concrete structure and manufacturing and installing method thereof

Abstract

The invention discloses a composite shear connection piece of a steel-concrete structure and a manufacturing and installing method thereof. The composite shear connection piece comprises shear connection piece bodies bent by reinforcing steel bars and bolt pin reinforcing steel bars penetrating through the shear connection piece bodies. The specific manufacturing and installing method includes the steps that steel beams are manufactured, and shear connection piece bodies are bent and welded; the steel beams are transported and lifted; concrete floor formworks are supported; the bolt pin reinforcing steel bars penetrate through the shear connection piece bodies, and the bolt pin reinforcing steel bars and the shear connection piece bodies are jointly bound to form a reinforcing steel bar mesh of concrete structure pieces; the formworks are disassembled after concrete pouring and normal maintenance are completed. According to the composite shear connection piece, as the shear connection piece bodies and the structural steel beams are welded and fixedly connected, and then a whole is formed through the bolt pin reinforcing steel bars penetrating through the shear connection piece bodies and the concrete structure pieces cast in place, the shearing strength and the rigidity of the steel-concrete composite structure are greatly improved, synergetic stressing between concrete plates and the steel beams is effectively achieved, and the composite shear connection piece has the advantages that the structure is simple, processing is easy and convenient, cost is low, construction cost is reduced, the site installing speed is high, and welding quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of civil engineering construction, and in particular relates to a composite shear connector of a steel-concrete structure and a manufacturing and installing method thereof. Background technique [0002] The steel-concrete composite structure can exert the respective mechanical properties of steel and concrete, with reasonable stress, high bearing capacity, high rigidity, fast construction progress, and good comprehensive economy. increasingly widespread effect. Among them, the shear connector is one of the key components in the steel-concrete composite structure. Its function is to prevent the two from sliding and separating horizontally at the interface, so that the steel member and the concrete member in the composite structure form a whole and work together. Work. [0003] There are many forms of shear connectors used in steel-concrete composite structures. At present, the commonly used technical means ...

AI Technical Summary

Problems solved by technology

The bending bar connector is easy to make, no special equipment is required for welding, and the ability to resist shearing and lifting is strong, but the requirements for its setting direction are relatively strict, and the requirements for construction are high, and the bent section of the connector is not conducive to concrete Arrangement of middle steel mesh
