Circular-section frame column stirrup connecting structure and stirrup mounting method

Abstract

The invention provides a circular-section frame column stirrup connecting structure and a stirrup mounting method. The circular-section frame column stirrup connecting structure comprises transverse auxiliary steel plates, longitudinal auxiliary steel plates and construction longitudinal bars, and a circular-section frame column comprises H-shaped steel; the stirrup installation method comprises the steps that the transverse auxiliary steel plates are welded to the positions, close to the bottom, of the two sides of a web of the H-shaped steel; the longitudinal auxiliary steel plates are welded to the positions, close to the top, of the two sides of a web of the H-shaped steel; the construction longitudinal bars are placed on the two sides of a web of the H-shaped steel, the bottom ends of the construction longitudinal bars are fixedly connected with the top faces of the corresponding transverse auxiliary steel plates, and the positions, close to the top ends, of the construction longitudinal bars are fixedly connected with the side faces of the corresponding longitudinal auxiliary steel plates; stirrups are bound to the structural longitudinal bars and the longitudinal steel bars of the circular-section frame column; and profile steel web punching and stirrup welding are omitted, and efficient, safe and environment-friendly installation of the stirrups is achieved on the premise that the effect of the stirrups is ensured.

Description

technical field [0001] The invention belongs to the technical field of frame column stirrup installation, and specifically provides a circular section frame column stirrup connection structure and a stirrup installation method. Background technique [0002] Steel-concrete (SRC) structure is a main form of steel-concrete composite structure. Steel-reinforced concrete columns are the main force-bearing members in SRC structures, which are also called steel-reinforced concrete columns. Steel concrete frame columns are generally used in high-rise or super high-rise building structures in fortified areas with high seismic intensity. Compared with ordinary steel columns, steel concrete columns can save a lot of steel, increase the stiffness of the section, overcome the shortcomings of steel structures such as fire resistance, poor durability, and easy buckling instability, so that the performance of steel can be fully utilized. Compared with ordinary reinforced concrete (RC) col...

Problems solved by technology

[0003]The common feature of this frame column is that it bears a large axial force, bending moment and bottom shear force, so its reinforcement is very large, and the longitudinal reinforcement and stirrup of the column are very Therefore, during the construction of stirrups, a large number of perforations and welding are required on the section steel, resulting in high labor costs and difficult quality control, which limits its application
