Nowadays, the active development of the Ministry of Housing and Urban-Rural Development is driving the continuous advancement of industrialization of buildings. In this situation, the prefabricated building is particularly important and is the core embodiment of the industrialization of the building. The new type of prefabricated building can not only avoid the problems of social production in traditional construction industry, such as unreasonable social production, unreasonable energy utilization and environmental pollution, but also effectively improve the construction quality under the premise of reducing production costs. This is a new type of prefabricated residential building that uses modular design, factory manufacturing, and on-site workshop assembly, making it a difficult construction method. This paper studies the construction technology of prefabricated houses, and hopes to provide reference and help for related projects.
