Five advantages of steel structure in residential applications
Steel structure is a structure made of steel as a force-bearing member. Steel structure houses are light in weight and low in foundation cost, suitable for weak foundations, easy installation, fast construction, short cycle, fast investment recovery, and less pollution to the environment during construction. In 1997, China's steel output reached 100 million tons, and in 1998, the rolled H-beam series was put into production, and relevant specifications and standards were issued, creating a good material and technical foundation for steel structures. .Foreign steel structure has been widely used in construction. High-rise buildings, large public buildings such as stadiums, stadiums, theaters, etc. are generally built, and their load-bearing skeletons are basically steel structures. In China, it was completed in 1996. The Shenzhen Diwang Building is 325 meters high and is the first super high-rise steel structure building in China. The Dalian Ocean Building, built in 1998, is a steel structure high-rise building (201 meters high, 51 floors). The supply is all completed by China itself, which indicates that the complete localization of high-rise building steel structures in China has started. Similarly, steel structures will also be widely used in residential buildings. Compared with other structures - brick-concrete structures and concrete structures, steel structures are It has advantages in the use of functions, design, construction, and comprehensive economy. The advantages of using steel structures in residential buildings are mainly reflected in the following aspects: 1. The functional areas can be reasonably arranged and the high strength of steel can be used in the design. The layout of large bays enables the building plane to be reasonably separated, flexible and convenient, and creates open-plan residences. However, traditional structures (brick-concrete structure, concrete structure) limit the freedom of space layout due to the nature of materials. , 3.6 meters, if it is too large, it will cause the thickness of the plate, the height of the beam, and the large column.“fat beam fat column”This phenomenon not only affects the appearance, but also increases the self-weight and increases the cost. During the secondary decoration, buyers often change the position of the wall by themselves, which increases hidden dangers. 2. In line with the requirements of housing industrialization and sustainable development, the steel structure is suitable for mass production in factories, with a high degree of industrialization, and can integrate advanced products such as energy saving, waterproofing, heat insulation, doors and windows into one, complete application, and integrate design, production, Construction integration, improve the level of housing industrialization. 3. Low comprehensive cost Due to light weight, lower basic cost, lower overall material consumption, lower direct cost, short construction period, and reduced indirect cost, the overall cost is low. 4. The construction is convenient and the construction period is short. The steel structure components can be produced in factories and installed on site. Due to the small amount of on-site work, the surrounding environment is less polluted. At the same time, the construction mechanization degree is high, which speeds up the construction speed. According to statistics, the same area of Compared with the concrete structure, the construction period of the steel structure can be shortened by one third, and the formwork material can be saved. 5. Light weight and good seismic performance. The steel structure of the building floors with the same building area has light weight. According to the comparison, the weight of the six-story light steel structure house is only equivalent to the weight of the four-story brick-concrete structure house. Moreover, the steel has ductility and can It consumes the energy brought by earthquakes better, so it has good seismic performance and high structural safety.
