What are the characteristics of Chongqing steel structure villas

Chongqing steel structure villa city is a very popular building form at present. The steel structure has the characteristics of fast installation and strong compressive capacity, and has begun to spread at home and abroad. The floor of Chongqing steel structure villa is composed of cold-formed thin-walled steel frame or composite beam, floor OSB structural plate, and supporting connection parts. Materials used are: oriented strand board, cement fiberboard and plywood. On these lightweight floors, each square meter can withstand loads of 316 to 365 kg. The weight of the floor structure is only 1/4 to 1/6 of the traditional concrete floor system, and the floor height is 100 to 120 mm higher than the ordinary concrete slab. The wall is mainly composed of wall columns, wall top beams, wall bottom beams, wall supports, wall panels, connectors, etc. The inner walls serve as load-bearing walls for the structure. The wall columns are C-shaped light steel members. The wall thickness is determined by the load where the wall is typically 0.84 to 2 mm. The spacing of pilasters is generally 400 to 600 mm. It can effectively bear and reliably transmit vertical loads, and the layout is convenient, but the wall structure cannot bear horizontal loads. Whether the house is sturdy or not is mainly reflected in the service life of the house and the safety performance in the event of natural disasters, rather than the intuitive experience of pinching and kicking. Traditional brick and cement buildings are masonry structures and rigid connections that cannot resist the instantaneous strength of earthquakes and typhoons. Huge external force tearing can lead to structural collapse and double damage to life and property. The main structure of the steel structure villa is a high-strength and high-galvanized keel structure system, which is connected by high-galvanized bolts to form an overall flexible structure. When encountering natural disasters (such as earthquakes, tsunamis, typhoons, etc.), the external force can be unloaded instantly, and the shear or deformation stress caused by the huge external force on the house can be released to ensure the safety of the entire house. Physical security, even if a larger earthquake and typhoon cause the collapse and deformation of the house, a flexible support space will be formed to ensure the safety of life and property. The panel composite structure wall not only has good integrity, but also avoids two damages to the human body caused by the collapse of the masonry structure. In the construction process of the steel structure villa in Chongqing, the light steel frame is welded on the foundation, and then the doors and windows are opened on the board with ordinary saw bars, and then various plates are inlaid on the steel frame in turn, and the construction area of ​​more than three floors exceeds the medium area villa. In less than a month, 12 workers only need 600 square meters. Completion of the main building, complete with most of the exterior and interior finishes. Building construction only takes 1/6 of the ordinary construction period. During the whole construction process, the complex construction process is simplified due to the collection of building materials and lightweight materials, so there is no need to use large construction machinery, so the laboratory. The power of the workers was greatly reduced. Chongqing steel structure villa is the basis for the classification of the building system, and its steel structure is a branch of the building system. Generally speaking, steel structure house means that the residential building is supported by a new type of lightweight, heat-insulating, heat-insulating, high-strength wall material. The industrialization of steel structure housing is the final product of steel structure housing. Through social production, the investment, development, design, construction and after-sales service of steel structure houses are centralized and unified to form a complete organizational form. The industrialization of steel structure housing is an inevitable trend in the development of steel structure housing.
