What is a prefabricated building? Are the components produced by PC factory reliable?

Assembled building refers to a building that transfers a lot of field work in traditional building methods to factories to manufacture building components and accessories (such as floors, wallboard, stairs, balconies, etc.). ) in the factory, transported to the construction site, assembled and installed on site through reliable connection.

Assembled buildings mainly include assembled concrete structures, steel structures and modern wood structures. Standardized design, factory production, assembly construction, information management and intelligent application are the representatives of modern industrialized production methods.

Assembled building planning has been intensively introduced since 20 15. At the end of 20 15, the evaluation standard of industrialized buildings was issued, and it was decided to popularize prefabricated buildings nationwide in 20 16, and made a breakthrough. 2015165438+10/4 The Ministry of Housing and Urban-Rural Development issued the Outline for the Modernization of Construction Industry, and it is planned that by 2020, prefabricated buildings will account for more than 20% of new buildings, and by 2025, prefabricated buildings will account for more than 50% of new buildings; On February 22nd, 20 16, the State Council issued "Guiding Opinions on Vigorously Developing Prefabricated Buildings", demanding to develop prefabricated buildings such as prefabricated concrete structures, steel structures and modern wood structures according to local conditions, and strive to make the proportion of prefabricated buildings in the newly-built building area reach 30% in about 10 years.
