L-shaped assembled core column steel plate shear wall and assembly construction method thereof

Abstract

The invention mainly relates to an L-shaped assembled core column steel plate shear wall. The shear wall comprises square edge stiffening columns, a plurality of circular core columns, a plurality offlat steel tie rods, webs and concrete; the circular core columns are evenly arranged in an L shape to form an L-shaped core column wall body, the corners and top of the wall body are provided with the square edge stiffening columns, and the square edge stiffening columns and the circular core columns are welded to one another through the webs by means of groove penetration welding; the flat steeltie rods are evenly arranged at the two outer side surfaces of the wall body, the two ends of each flat steel tie rod are welded to the two corresponding adjacent core columns respectively, and the outer side portions of the circular core columns and the square edge stiffening columns are filled with the concrete; the upper end of each circular core column is symmetrically provided with four notches, the upper end of each square edge stiffening column is symmetrically provided with four notches, and the lower ends of the circular core columns and the lower ends of the square edge stiffening columns are all provided with horn-shaped necking ports getting smaller downwards. The L-shaped assembled core column steel plate shear wall is good in overall performance, 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 performance is good, and the seismic performance is good.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to an L-shaped assembled core column steel plate shear wall and an assembly construction method thereof.

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
