Problems solved by technology

There are two types of double-steel plate shear walls: outer-wrapped steel plates and built-in steel plates. The outer-wrapped double-steel plates can also be used as formwork, which is convenient for construction. In the past, there were few studies on double-steel combined shear walls, and they were limited to straight cross-sections. There is no research on composite shear walls with I-shaped cross-section double steel plates

Embodiment 1

[0027] Such as figure 1 As shown, the I-shaped multi-cavity double-steel plate shear wall with steel mesh hidden inside includes flange multi-cavity steel pipe 1, web outer steel plate 2, cavity partition 3, horizontally distributed steel bars 4, longitudinally distributed steel bars 5 and poured in the wing Concrete in flange and web walls6. It adapts to the arrangement of shear walls in the building structure, and at the same time gives full play to the role of multiple anti-seismic defense lines.

[0028] In this embodiment, the I-shaped multi-cavity double-steel plate shear wall with reinforced mesh inside can be manufactured as follows:

[0029] 1) According to the thickness of the wall, the outer steel plate 2 of the web is positioned, and welded on the inner side with the partition plate 3 of the web cavity.

[0030] 2) Pass the horizontally distributed steel bar 4 through the reserved small hole of the partition plate 3;

[0031] 3) Arrange longitudinally distribute...

Abstract

The invention relates to a double-steel-plate combined shear wall, in particular to an I-shaped multi-cavity double-steel-plate shear wall with built-in steel mesh reinforcement and a manufacturing method. According to the I-shaped multi-cavity double-steel-plate shear wall with the built-in steel mesh reinforcement, the I-shaped section is applicable to the arrangement mode of a shear wall body in a building structure, the space between the inner sides of two steel plates is filled with concrete, buckling deformation of the steel plates can be effectively restrained, and the buckling strength of the steel plates is improved; due to the fact that the internal concrete is restrained by the steel plates on the two sides, cavity separating plates and steel reinforcement meshes in a double mode, the elastic-plastic deformation capacity and ultimate compressive strength of the concrete are improved; the flange portion of the shear wall body with the I-shaped section has a good restraint effect on a web wall, the bearing capacity, in the plane, of the combined shear wall and the bearing capacity, outside the plane, of the combined shear wall are remarkably improved, and thus the combined shear wall can have the high bearing capacity and the high elastic-plastic deformation capacity.

Description

technical field [0001] The invention relates to an I-shaped multi-cavity double-steel plate shear wall with reinforced mesh inside and a method thereof, which is mainly used in the field of energy dissipation and shock absorption control in building structures. Background technique [0002] With the development of society and the improvement of economic level, there are more and more high-rise buildings. Reinforced concrete high-rise buildings with large quantities and wide areas are usually composed of beams, columns, floors, shear walls and cores. The shear wall and the tube body composed of the shear wall are the core parts of the high-rise building's seismic resistance, and the seismic performance of the shear wall and the core tube plays a vital role in the safety and reliability of the high-rise building. Especially in recent years, there are more and more large and complex high-rise buildings pursuing individualization, and the requirements for the seismic performanc...
