Cross-shaped assembly type core column steel plate shear wall and assembly construction method thereof

Abstract

The invention mainly relates to a cross-shaped assembly type core column steel plate shear wall. The cross-shaped assembly type core column steel plate shear wall comprises square edge stiffening columns, a plurality of round core columns, a plurality of flat steel tying rods, webs and concrete. The multiple round core columns are evenly arranged to be in a cross shape to form a cross-shaped corecolumn wall, the four top ends of the cross-shaped core column wall are provided with the square edge stiffing columns correspondingly, the square edge stiffening columns and the round core columns are welded mutually through the webs by adopting slope penetration weld, the multiple flat steel tying rods are evenly arranged on the two outer side faces of the wall, the two ends of each flat steel tying rod are welded to every two adjacent core columns, and the outer sides of the round core columns and the square edge stiffening columns are filled with concrete. The upper ends of the round corecolumns and the square edge stiffening columns are each symmetrically provided with four notches, and the lower ends of the round core columns and the square edge stiffening columns are each providedwith a horn-shaped contraction port contracting downwards. The cross-shaped assembly type core column steel plate wall is good in integrity, easy to manufacture and convenient to splice, and the working efficiency is improved. Meanwhile, the connection strength among the components is high, the structural safety is high, and the anti-seismic property is good.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a cross-shaped assembled core column steel plate shear wall and an assembly construction method thereof. Background technique [0002] Building industrialization is a low-carbon, green, environmentally friendly and efficient construction method. It is prefabricated in the factory and transported to the site for assembly and assembly. It overcomes the disadvantages of the traditional construction mode, effectively improves the construction production efficiency, and improves the structural safety performance. Energy saving and emission reduction, improving resource utilization and reducing construction costs. [0003] At present, for prefabricated buildings, there are mainly two issues that affect structural safety: 1. The seismic performance of components; 2. The connection strength between components. In order to improve the seismic performance of traditional reinforced co...

Problems solved by technology

[0003] At present, for prefabricated buildings, there are two main issues affecting structural safety: 1. Seismic performance of components; 2. Connection strength between components

In order to improve the seismic performance of traditional reinforced concrete shear walls, a large number of steel bars need to be configured to resist seismic shear forces. At present, when prefabricated shear walls are manufactured and processed in factories, the steel mesh and steel cages have not been fully automated. Still rely on manual binding, low production efficiency, difficult to guarantee quality, high labor costs, and difficult to meet the needs of automated pouring production lines

At present, the connection between traditional prefabricated reinforced concrete shear wall components mostly adopts grouting sleeve connection, grout anchor connection and other forms. The above connection forms require high processing precision of components, difficult construction and low efficiency. At the same time, due to internal grouting If the quality is not well controlled, it will seriously affect the connection strength between components and reduce the safety performance of the overall structure
