Fabricated steel structure residence system and construction method thereof

Abstract

The invention discloses a fabricated steel structure residence system and a construction method thereof. The fabricated steel structure residence system includes a vertical unit, horizontal beams anda fabricated wall panel; the vertical unit includes a concrete-filled steel tube single column, a corrugated plate shear wall unit and a short-limb special-shaped corrugated plate shear wall unit; thecorrugated plate shear wall unit and the short-limb special-shaped corrugated plate shear wall unit include concrete-filled steel tube stand columns, connecting beams and transverse rib corrugated plates, and restraint frames of corrugated plates are formed by the concrete-filled steel tube columns in the units and the connecting beams at the floor heights; the horizontal beams are connected withvertical members to form an overall structure; and the fabricated wall panel is fixed between the upper layer horizontal beams and the lower horizontal beams by adopting bolts. According to the fabricated steel structure residence system, the small size concrete-filled steel tube columns are adopted as vertical load bearing members, the members are filled with concrete in a factory, and the corrugated plate shear walls provide structural lateral resistance; the fabricated steel structure residence system and the construction method have the beneficial effects that full prefabrication of mainstructural members can be realized, and site construction processes are reduced; the corrugated plate wall can reduce the use amount of steel and ensures lateral resistance; and the vertical members can be hidden in a wall body, and the residence building use demands are met.

Description

technical field [0001] The invention belongs to the technical field of residential buildings, in particular to an assembled steel structure residential system and a construction method thereof. Background technique [0002] Most of the existing steel structure houses are steel plate shear wall structure systems, such as steel plate composite shear walls, steel tubes arranged and welded to form a steel tube bundle shear wall system, similar systems are not flexible enough in application, and consume a large amount of steel. [0003] And the steel structure residential shear wall system that the existing steel plate or steel pipe is combined with concrete to form, also has the following defects: [0004] 1. When pouring and forming a prefabricated section on the 3rd to 4th floor in the factory, the weight of the entire shear wall component will be too large, and it is difficult to meet the hoisting requirements on site. Therefore, most of them adopt the method of pouring concr...

AI Technical Summary

Problems solved by technology

[0004] 1. When pouring and forming a prefabricated section on the 3rd to 4th floor in the factory, the weight of the entire shear wall component will be too large, and it is difficult to meet the hoisting requirements on site. Therefore, most of them adopt the method of pouring concrete on site, and it is difficult to realize assembly construction and rapid construction. Require

[0005] 2. The cross-sectional size of the column is relatively large, which will cause problems such as exposed beams and leaky columns when it is used in residential buildings, which is not conducive to the aesthetic and comfort requirements of the residential interior space, and is not conducive to the layout of residential homes

[0006] 3. In the existing steel frame support structure steel structure residence, the prefabricated slats cannot be applied due to the support setting

[0007] 4. In the application of the existing steel plate shear wall type steel structure residence, when the traditional flat steel plate is used as the shear wall, sufficient thickness is required to delay the overall buckling effect of the plate surface, and the shear resistance cannot be fully exerted due to buckling, and the overall drum

If combined steel plate shear walls and flat steel plate shear walls are used for steel structure houses, thin steel plates will result in poor out-of-plane rigidity, which will make welding deformation difficult to control during processing, and the increase in steel plate thickness will increase the amount of steel used. The effect is obvious, and the cost increases

And in the construction of combined steel plate shear wall, when the shear wall steel plate is thin, it is easy to produce outward buckling of the enclosure steel plate, which makes it difficult to ensure the construction accuracy and exert the mechanical performance
