Prefabricated buildings started to attract people's interest in the early 20th century, and finally realized in the 1960s. Britain, France, the Soviet Union and other countries first tried. Because prefabricated constructions are fast and production costs are low, they are rapidly being promoted around the world. In recent years, the global prefabricated construction market has developed rapidly. In 2016, the market size increased to US $ 160 billion, and the market growth rate remained above 10%. The market size and development potential are huge.
China's application of prefabricated buildings began around the 1950s, and until the 1980s, prefabricated prefabricated buildings flourished nationwide. From the 1990s to the beginning of the 21st century, due to technical and other reasons, they fell into a stagnant state, and nearly Over the years, with the rapid development of China's economy, the improvement of construction technology and the rise in labor costs, prefabricated buildings have been re-enabled and entered a new stage of development with new technologies.
At present, China has already had some representative pre-fabricated prefabricated construction projects and demonstration projects. Some achievements and progress have been made in the research of structural systems, but there are still some key issues to be resolved in practical applications. Prefabricated buildings are developing in the direction of standardization, generalization, high quality, energy saving and environmental protection of component production processes, and China is accelerating to a new stage of development in the process of industrialization of construction.
After doing prefabricated construction, some wall components, stairs, balconies and other components are already made in the factory. Workers' on-site operations are only the steps of positioning, positioning, and installation, so woodworking, rebar, and concrete workers Demand will be greatly reduced. However, crane drivers, riggers, welders, surveyors, and some high-skilled jobs may become more popular.
In 2016, the market scale of China's fabricated construction industry reached more than 300 billion yuan, and it has become a huge industry with a scale of hundreds of billions. The growth rate in 2016 has reached an astonishing 3.92 times. At present, China has more than 30 provinces and cities. Guidance and related supporting measures for the development of prefabricated buildings and construction industrialization have been issued, and many places have made clear requirements for the development of construction industrialization. In accordance with this development trend and the requirements of the State Council of the Communist Party of China on "striving for about 10 years to make the proportion of prefabricated buildings account for 30% of new construction area", based on the current status of prefabricated buildings in China, Within five years, China's prefabricated buildings will become a blue ocean market with a market size of one trillion.
