As China's urbanization rate continues to increase, China annually builds a large number of dwellings in towns and cities. For traditional brick-and-concrete structures, it requires a large number of bricks. To excavate a large amount of soil to burn bricks, it will make China's cultivated area Keep decreasing. Compared with the traditional brick mixed reinforced concrete residential buildings, steel residential buildings with energy saving, environmental protection, short construction period, occupy less resources and good seismic characteristics.
Common structure of steel residential houses for residential use, has unique advantages, including: First, light weight. Steel structure residential buildings can reduce about 30% of the weight of the building, which is conducive to the construction of high-rise buildings, especially in areas with low geological carrying capacity and areas with high earthquake intensity, whose comprehensive economic benefits are superior to those of ordinary residential building systems. Followed by the flexible layout, large room, room type, about to increase the construction area of 3% to 5%. Due to its full flexibility, modifiability and safety, it is beneficial to meet the living needs of modern people. The third is to more easily achieve industrialization, finalization and mass production, increase labor productivity, and at the same time greatly shorten the construction period. According to the research, the construction period of steel structure construction can be shortened by half than the construction period of concrete construction, the workload can be reduced, and the energy-saving index can reach 50%.
However, some experts also pointed out that the steel structure itself does not have any problems. However, as a residential building, many supporting functions have yet to be solved. In addition, there are no relevant building materials with good quality and reasonable price at present, and how to perfectly lay pipes and lines Combined with the steel structure, how to control the price within the acceptable range of ordinary people, these are the problems to be solved.
