Compared with the traditional building system, the steel structure residential system has the following advantages:
1. Easy to industrialize the production The steel structure residential system consists of prefabricated components (steel frames, connectors) and supporting layers, doors and windows, partitions, etc., which conforms to the engineering characteristics of industrialized production and on-site assembly.
2. Green, environmentally friendly and energy-saving. It has less damage and pollution to the environment, is easy to transform and disassemble, and most materials can be recycled. Therefore, steel structure buildings meet the requirements of green buildings, and new materials such as steel structures and their supporting lightweight materials (such as various lightweight wall panels) meet the requirements of energy-saving buildings.
3. Greater space utilization Lightweight roof and wall structures are used. Due to the high strength of the supporting steel structure and the small amount of materials required, the material volume can be smaller and the weight is lighter. . . Therefore, the use space is larger and the span can be larger. The apartment type is flexibly separated, and there are no columns in the room, which meets the flat use function of the residential building; at the same time, it can improve the utilization rate of residential space, sandwich structure, suitable for residential decoration with staggered levels of vertical parts. In addition, the required component section is smaller, and the space utilization rate is increased by 5~8% within the same building area.
4. Steel structures can be made into various shapes, making the design more flexible and advanced, and can complete the building functions and architectural art features according to the designer's intentions.
5. Steel-structured houses have light weight, small size, good ductility, and good seismic resistance. In earthquake damage analysis, the stiffness of steel-structured buildings is significantly better than that of brick-concrete structures and reinforced concrete frame structures. Earthquakes in the United States, Japan, and Taiwan have improved.
6. Due to the light weight of steel-structured houses, the foundation load is correspondingly reduced, and the construction difficulty and cost of foundation projects are reduced.
7. Short construction period and quick results of investment funds In addition to the civilized construction of the foundation construction site, all components are standardized by professional factories, with fast construction speed and half the construction period of traditional buildings; components are transported to the site for assembly, construction is civilized, wet operation noise is small, dust and construction waste are less, and environmental protection requirements are met; construction operations are less affected by weather and seasonality (can be carried out in the steel structure workshop in winter), factory production and on-site installation are carried out in parallel, and even some standard residential systems can be customized for simultaneous construction, which greatly shortens the construction period and capital occupation period.
8. High comprehensive benefit index The direct cost of steel structure housing system is slightly higher than that of concrete structure by about 5%. But its economic and social benefits are relatively high. In today's fierce competition among real estate enterprises, it is a reflection of the comprehensive strength of real estate enterprises, and has a great impact on improving the brand awareness of enterprise products and the social reputation of enterprises.
