A giant steel-reinforced concrete column with a built-in lattice steel frame

Abstract

A giant steel reinforced concrete column with built-in lattice steel ribs comprises a reinforced concrete column, and lattice steel ribs are longitudinally embedded into the steel reinforced concrete column and are firmly combined with the steel reinforced concrete column through multiple studs welded to the outer side faces. The problems that an existing steel reinforced concrete column is high in manufacturing cost and difficult in construction difficulty are solved, and the giant steel reinforced concrete column is simple in manufacturing method, convenient to construct and suitable for high-rise structure on various scales and has remarkable economic benefits.

Description

technical field [0001] The invention relates to a steel reinforced concrete column. In particular, it relates to a giant steel-reinforced concrete column with a built-in lattice steel frame. Background technique [0002] Steel-reinforced concrete columns are often used in high-rise structures. Steel-reinforced concrete columns add steel reinforcement to reinforced concrete columns to improve the ductility and stiffness of the column and increase the axial compression ratio limit of the column. Compared with reinforced concrete columns, steel reinforcement Concrete columns have a smaller section. As the height of the building increases, the cross-sectional size of the steel reinforced concrete column needs to be made larger, that is, the giant steel reinforced concrete column. The main problems of the giant steel reinforced concrete column are: [0003] 1. The section size of the giant steel reinforced concrete column is large, and the internal steel bone is also increased ...

AI Technical Summary

Problems solved by technology

[0003] 1. The section size of the giant steel reinforced concrete column is large, and the internal steel bone is also increased accordingly. If a single round steel frame or giant steel frame is installed in a conventional way, the steel consumption of the steel reinforced concrete column will increase, and the economic benefit will be poor;

[0004] 2. Due to the large size of the single steel frame installed in the giant steel reinforced concrete column, in order to enhance the bite force between the steel frame and the external concrete, it is necessary to install many stiffeners on the side of the steel frame, which greatly increases the welding workload and increases the size of the steel frame column. construction difficulty
