Do you know the characteristics of prefabricated steel structure houses?

With the gradual implementation of the national supply-side structural reform and the construction industry transformation and upgrading strategy, the development of prefabricated steel structure buildings has become an important way to transform and upgrade my country's construction industry and realize construction industrialization. Prefabricated steel structure housing is not only an important guarantee for improving building quality and reducing earthquake disasters, but also an important measure to relieve excess steel pressure and form a strategic steel reserve, and an important carrier for developing a low-carbon economy and achieving green environmental protection. Features of prefabricated steel structure houses (1) Light weight, high strength and good earthquake resistance From the perspective of materials, although the quality of steel structures is generally 3.2 times that of ordinary concrete, the strength of steel products can reach more than eight times that of concrete. From the comparative analysis of the stress and strain of steel and concrete, steel has good ductility and uniform internal structure. In earthquakes, steel has good deformation ability, which can resist the impact of earthquakes on building structures, thereby reducing the impact of earthquakes on buildings. degree of damage. (2) The prefabricated steel structure house with high degree of industrialization is the same as other prefabricated buildings. All structural components and parts are standardized in production, construction and installation, and scientific organization and management by mass production in the factory. Change the traditional way of building. (3) The short-construction-period prefabricated steel-structured residences change from 'on-site construction' to 'factory-made' through unified standard production, integrated composite floor slabs, modular components such as columns and walls, and factory-based component production, reducing construction site costs. Environmental and noise pollution, no concrete construction and maintenance period is required on site, and the construction period is only 1/4~1/5 of the traditional building, saving the construction period cost of the building. (4) Green environmental protection and energy saving The amount of construction waste in my country accounts for 30% to 40% of the total waste. It can be seen that the impact of the construction industry on the environment and resources is extremely bad. Compared with traditional buildings, the building materials used in prefabricated steel structure buildings are mainly steel, and the recycling rate of materials is as high as 70%. /4 or so, effectively reducing the impact of construction waste on the environment, in line with the requirements of building energy conservation and environmental protection. (5) Flexible space layout The new lightweight enclosure plate in the assembled steel structure house has large structural space span and flexible layout, which can increase the usable area by 5% to 8%. At the same time, various pipelines can be buried in the wall. In the body and floor structure, the decoration is in place at one time and maintenance is reduced, which can well meet the requirements of the residents. (6) Ease the pressure of excess steel energy In recent years, my country's steel production has continued to increase, although the growth rate has slowed down, but the current situation of oversupply makes steel companies must find another way. At this time, the development of prefabricated steel structure houses can effectively utilize steel, which can not only relieve the pressure of excess steel energy, but also make up for the deficiencies of prefabricated reinforced concrete houses.
