Prefabricated housing is the current trend of housing construct


    Prefabricated houses are residential buildings constructed by industrialized production methods. Some or all components of the residential buildings are prefabricated in factories, then transported to the construction site, and the components are assembled by reliable connection methods. They are also called Residential industrialization or industrialized residential buildings.

    Prefabricated housing is conducive to energy conservation and emission reduction, promoting green and safe construction methods, improving housing quality, improving living environment and promoting industrial structure adjustment. It is the current trend of housing construction development.

    Japan put forward the concept of prefabricated house in 1968. In 1990, they adopted the mode of component and factory production, with high production efficiency and variable internal structure of the residence to meet diversified demands. And Japan has a very distinctive feature, from the beginning to pursue high-rise residential accessories production system. This kind of production system can meet the demand of Japan's densely populated residential market. More importantly, Japan has passed legislation to ensure the quality of concrete components. It has formulated a series of policies and standards in the area of prefabricated residential buildings. At the same time, it has also formed a unified modular standard, which solves the contradiction between standardization, mass production and diversified demand.

    The following is an introduction to the current situation of Prefabricated building in Japan:

    Japanese standards include building standards law, building standards law implementation order, Ministry of Land, Infrastructure, Transport and Tourism notices and circulars, association (society) standards, enterprise standards, etc., covering design, construction and other contents, of which the relevant technical standards and guidelines of prefabricated concrete structure formulated by AIJ of Japan Architecture Society. The Japanese Prefabricated Building Association, established in 1963, has made great contributions in promoting the development of prefabrication technology in Japan. The Association has successively established a qualification certification system for PC construction method welding technology, a qualification certification system for prefabricated and assembled residential decorators, a quality certification system for PC components, and a review system for PC structures. It has compiled a series of Prefabricated Building Technology Integration, including shear wall precast concrete (W-PC), shear wall frame precast reinforced concrete (WR-PC) and cast-in-situ equivalent frame precast reinforced concrete (R-PC).
