Novel stirrup shearing connector as well as manufacturing and installing methods thereof

Abstract

The invention discloses a novel stirrup shearing connector as well as manufacturing and installing methods of the novel stirrup shearing connector. The connector comprises a stirrup shearing connector, a stirrup, longitudinal reinforcing steel bars, a steel beam, a template, end plates and transverse reinforcing steel bars. The manufacturing and installing methods comprise the following steps: manufacturing the steel beam and the stirrup and welding the component, placing the longitudinal reinforcing steel bars at four corners inside the stirrup to complete binding; hoisting the structure; binding the reinforcing the steel bars by a floorboard supporting and protecting template; casting concrete; normally maintaining the concrete and then dismounting the template. According to the invention, a steel reinforcement cage which is bound by the longitudinal reinforcing steel bars and the stirrup is welded with the upper wing edge of the steel beam, and then bound with the transverse and the longitudinal reinforcing steel bars in a concrete plate to form an integer, so that the shearing resistance and rigidity of the steel beam-concrete combined component are effectively improved, thereby achieving cooperative stress of the concrete and the steel beam, a simple structure and convenience in construction, restricting lifting deformation, increasing plasticity (i.e., deformable capacity) of the concrete and the steel beam, and improving the stability and the reliability of the concrete and the steel beam.

Description

Technical field [0001] The invention belongs to the technical field of steel-concrete composite beam connectors, and particularly relates to a novel stirrup shear connector and a preparation and installation method. Background technique [0002] The steel-concrete composite beam is a flexural member that connects steel beams and concrete slabs into a whole through shear connectors. Shear connectors are the key components of steel-concrete composite beams. They have two main functions: one is to withstand and transmit the longitudinal shear between the steel beam and the concrete slab; the other is to resist the difference between the concrete slab and the steel beam. The flipping of time works. Generally speaking, shear connectors can be divided into rigid connectors and flexible connectors. Specifically, they can be divided into the following four types: stud connectors, bent steel reinforcement connectors, section steel shear connectors, and holes Steel plate connector. [000...
