On the development of light steel villa in China
And future trends
 Light steel villa is a kind of light steel residence. It is a prefabricated house with light steel structure as the main body and new materials as the main wall. It has the characteristics of sound insulation and thermal insulation. It is a new project introduced by our country, which is popular in foreign countries and has a bright future.
 
 
The historical evolution of prefabricated buildings in China
       China began to develop prefabricated buildings from the 1950s to 1960s. By the 1980s, many parts of the country have formed an integrated system of design, production, construction and installation. The application popularity of prefabricated buildings and masonry buildings with prefabricated hollow floors has reached more than 70%. However, due to the immature technology, high cost, lack of integrity, as well as the design and construction technology of prefabricated buildings can not keep up with the changes of social demand and Technological Development and other factors, by the mid-1990s, prefabricated buildings have been completely replaced by cast-in-place concrete building system.  
    
However, the relative working time of cast-in-place operation is relatively long, the labor intensity of the construction site is high, and there are many potential safety hazards. With the increasingly serious shortage of construction labor, the annual increase of labor cost, the difficulty in controlling the construction quality of cast-in-place operation, and the high energy consumption in the construction process, it is necessary to continue to explore a new construction mode. In this context, in recent years, the prefabricated buildings are more and more popular in China. Attach importance to.
 
Why should we vigorously develop prefabricated buildings in China?
        First of all, in order to protect the land and resources environment and prevent the loss of land and resources, the state strictly controls the collection of sand and stone materials, and vigorously develops the environmental protection industry. Second, China's steel production ranks first in the world, and there is a serious overcapacity. However, the proportion of steel used in the construction industry is far lower than that of developed countries. The light steel structure civil housing construction technology conforms to the national construction industry. Guidance.
        Since 2016, the State Council and the Ministry of housing and urban rural development have successively issued policies and technical standards to promote the transformation of the construction industry and vigorously develop prefabricated buildings. It is required that by 2020, the proportion of national prefabricated buildings in new buildings should reach more than 15%, and that of key areas should reach more than 20%. And 31 provinces, cities and autonomous regions in the country have introduced the goal of prefabricated building and supporting policies. The guiding opinions of the general office of the State Council on vigorously developing prefabricated buildings put forward to develop prefabricated concrete structures, steel structures, modern wood structures and other prefabricated buildings according to local conditions with Beijing Tianjin Hebei, Yangtze River Delta and Pearl River Delta as the key areas.
 
Development prospect of light steel villa
       With the guidance of relevant development objectives and policies issued by the state and the industry in succession, and in the face of the urgent needs of the transformation and upgrading of the construction industry in all parts of the country, more than 20 provinces and cities in China have successively issued policies to support the development of the construction industry, vigorously promote the construction of Industrialization Bases and pilot demonstration projects, and with the improvement of technology, the progress of management level, assembly type. There will be a broad market and space for construction.
 
Prefabricated buildings can be divided into timber structure, concrete structure and light steel structure. The price of light steel structure is the lowest, so it is gradually popularized. Now with the development of society and the improvement of living standards, people's aesthetic is also rising. Ordinary civil buildings can no longer meet people's needs, and the architectural design of light steel villa and the unique materials of light steel can be flexibly assembled, which provides the possibility for the realization of various architectural styles. Therefore, the more beautiful and advantageous light steel villa is gradually replacing the traditional brick and concrete structure house.
 
At present, the proportion of residential steel structure in China is less than 5%, compared with almost more than 50% in developed countries, China is still in its infancy, and there is still a lot of room for development of residential steel structure. According to the market forecast report of prospective industry research institute, the steel structure is expected to move the trillion yuan green building market in the future, so the prospect is broad.
