Prefabricated buildings are buildings assembled from prefabricated components on construction sites, known as prefabricated buildings. According to the form and construction method of prefabricated components, it can be divided into five types: block building, panel building, box building, skeleton panel building, and raised floor building..

2. Slow development stage (1978-2010).

① At the end of 2015, the “Evaluation Standards for Industrial Buildings” were released, which decided to comprehensively promote prefabricated buildings nationwide in 2016 and made breakthrough progress;.

② On November 14, 2015, the Ministry of Housing and Urban Rural Development issued the “Outline for the Modernization of the Construction Industry”, which plans to have prefabricated buildings accounting for more than 20% of new buildings by 2020 and more than 50% of new buildings by 2025;.

③ On February 22, 2016, the State Council issued the “Guiding Opinions on Vigorously Developing Prefabricated Buildings”, which required the development of prefabricated concrete structures, steel structures, and modern wooden structures according to local conditions, striving to achieve a proportion of 30% of the newly constructed building area in about 10 years;.

④ On August 28, 2020, the Ministry of Housing and Urban Rural Development, the Ministry of Education, the Ministry of Science and Technology, and the Ministry of Industry and Information Technology jointly issued the Several Opinions on Accelerating the Development of New Building Industrialization. Suggestions: We should vigorously develop steel structure buildings and promote prefabricated concrete buildings..

The Crystal Palace, built in London in 1851 with an iron frame embedded in glass, was the world’s first large-scale prefabricated building. After World War II, there was a severe housing shortage in European countries and Japan, which urgently demanded solutions to the housing problem and promoted the development of prefabricated buildings. By the 1960s, prefabricated buildings were widely promoted..

With the development of modern industrial technology, building houses can be manufactured in batches and complete sets like machine production. Just transport the prefabricated building components to the construction site and assemble them..

Prefabricated architecture began to attract people’s interest in the early 20th century and finally became a reality in the 1960s. Britain, France, the Soviet Union and other countries were the first to make attempts. Due to the fast construction speed and low production cost of prefabricated buildings, they have quickly been promoted around the world..

Early prefabricated buildings had a rather rigid and uniform appearance. Later, people made improvements in design, increasing flexibility and diversity, allowing prefabricated buildings to be built in batches and with diverse styles..

From the classification of structural materials, prefabricated buildings can generally be divided into prefabricated concrete systems (PC), prefabricated steel structure systems, and prefabricated wood structure systems. At present, PC is still the main application in China..

“External and Internal Casting” PCF (Prefabricated Prefabricated External and Internal Wall Panel) Shear Wall System; Double sided Composite Plate Shear Wall System; Fully Assembled Integrated Shear Wall System; Prefabricated Frame cast-in-place Shear Wall System; Fully Assembled Integrated Frame System; Elevated System..
