Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] figure 1 What is shown is the basic structure diagram of an embodiment of the double steel plate structure shear wall of the present invention.

[0024] As shown in the figure, the double-steel plate structure shear wall includes an inner steel plate 1 and an outer steel plate 2, and the two layers of steel plates are welded and spliced ​​by several steel plates; the opposite sides of the inner steel plate 1 and the outer steel plate 2 The stiffened plate 3 and the connecting steel bar 4 are welded together; the opposite sides of the inner steel plate and the outer steel plate are also welded with studs 5; concrete is poured in the wall.

[0025] As a preference, the welds on the inner steel plate 1 and the outer steel plate 2 and the welds between the two steel plates and the stiffening plate 3 are V-groove welds with a backing plate 6 added. ...

Abstract

The invention discloses a shear wall with a double-steel plate structure, which comprises steel plates, stiffening plates, connecting steel bars, and studs; the steel plates are spliced ​​by welding, and the opposite sides thereof are connected together by welding stiffening plates and connecting steel bars; Studs are welded on opposite sides of the inner steel plate and the outer steel plate; concrete is poured in the wall. This kind of structure can strengthen the lateral stiffness of the shear wall, and weaken the shrinkage and creep of the concrete when pouring concrete in the wall, so that the bearing capacity and ductility of the wall are significantly enhanced, and the seismic performance is improved. The invention also discloses a construction method for building the shear wall. Firstly, the processing unit is divided, and then the steel plate of the unit is hoisted on the installation foundation pre-embedded with the foundation embedded parts to form the wall, and then the verticality of the wall is corrected, and the wall joint is welded. , Concrete is poured on the wall; inner and outer operating platforms are also erected during construction.

Description

technical field [0001] The invention relates to a wall of a building, in particular to a double steel plate structure shear wall and a construction method thereof. Background technique [0002] As a lateral force-resistant structure with better seismic performance, shear walls are widely used in buildings with high seismic requirements in high-intensity earthquake regions such as North America and Japan. Under the action of earthquake, the ductility exhibited by the shear wall is an important index to judge the seismic performance of the shear wall. The structure of the traditional shear wall is mostly reinforced concrete structure, which is easy to crack in the earthquake, and once the concrete cracks, the ductility of the shear wall basically disappears, and it is no longer earthquake-resistant. Moreover, when installing the shear wall of the existing structure, the installation accuracy and installation deformation are difficult to control. In addition to factors affect...
