Hooped steel reinforced concrete beam-column joint of core area U-shaped column

Abstract

The invention provides a hooped steel reinforced concrete beam-column joint of a core area U-shaped column, which relates to the field of constructional engineering. The hooped steel reinforced concrete beam-column joint of the core area U-shaped column comprises a column type steel flange plate, a column type steel web plate, a column horizontal stiffened steel plate, a column longitudinal bar, a column hoop, a column U-shaped hoop and a column concrete as well as a beam type steel flange plate, a beam type steel web plate, a beam longitudinal bar, a beam hoop and beam concrete; the beam-column joint core area is steel reinforced concrete structure building or structure of the U-shaped hoop. In the joint core area, the original closed hoop is replaced with the U-shaped hoop which is suitable for the structural forms at the beam-column joints of high-rise and super high-rise buildings. According to the invention, a column hoop through hole which is formed on the beam type steel web plate due to the need of enabling the column hoop to penetrate through the beam type steel web plate in the common steel reinforced concrete beam-column joint is avoided; one procedure is reduced in the member manufacturing process; the trouble of first penetrating through the reinforcing steel bar for making the hoop and then carrying out bending molding and segmental welding on the reinforcing steel bar during construction is prevented; and the beam-column joint can be manufactured in advance so that the construction period is shortened and the construction costs are saved.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a U-shaped column stirrup steel concrete beam-column node in the core area. Background technique [0002] Steel-reinforced concrete structure (or steel-reinforced concrete structure) is composed of hot-rolled or welded steel, bound longitudinal reinforcement and horizontal stirrups, and poured concrete. In recent years, due to the advantages of both steel structure and concrete structure, the steel-concrete structure has high bearing capacity, good seismic performance, and can reduce project cost, shorten construction period, and save materials, etc., it is more and more widely used in high-rise and superstructure Among high-rise buildings. [0003] In my country's "Technical Regulations for Steel-reinforced Concrete Composite Structures" (JGJ 138-2001) and "Technical Regulations for Steel-reinforced Concrete Structures" (YB 9082-2006), the beam-column joints consist of ...
