Different from the traditional concrete pouring, the stairs, beams, columns, and wallboards of the fabricated steel structure high-rise buildings are all independent building components that are poured, and can be installed with lifting tools
Advantage:
1. Good architectural adaptability: the size of the components of the implicit frame steel structure residential system is small, which is easy to be hidden in the main building walls. There are no convex beams and columns indoors, which is suitable for the layout of residential buildings.
2. High degree of standardization: the specification standard of wide concrete-filled steel tube column and narrow flange H-shaped steel beam, 5-8 kinds of sections can cover more than 85% of the component selection requirements in conventional residential buildings.
3. Simple factory fabrication: wide steel pipes and hot rolled narrow flange H-shaped steel can be purchased directly, and the connection node of beam column without diaphragm is simple in structure, convenient in factory fabrication, and low in equipment requirements.
4. Mature supporting products: fabricated steel bar truss floor bearing plate is used for floor slab, aerated concrete batten is used for internal partition wall, and the external wall is selected according to product positioning. The supporting components are mature in technology.
5. Controllable comprehensive cost: the product design is simple, the steel consumption can be saved by 10% compared with similar domestic products, the product production is simple, the production cost is low, and the comprehensive cost can be saved by 20%.
