Prefabricated house building and construction method thereof

technical field

The invention relates to a house building, in particular to a prefabricated house building and a construction method thereof, which belong to the field of building technology.

Background technique

Integrated housing refers to a building that is industrially produced and integrated with structures, parts, equipment, etc. under the principles of standardization, modularization, and serialization, and can realize assembly construction on site. With the development of my country's economic strength, coupled with the increase in the number of traditional buildings, the gradual scarcity of land resources, the increasing pollution of cities, the aggravation of climate warming and the difficulty of handling construction waste, integrated housing is gradually being recognized, and many development zones, Real estate developers, tourist attractions, new rural construction, and individuals all value this very advantageous product. The rapid promotion of integrated housing has become a highlight in the field of new materials and construction in this century.

Low-rise integrated residences are very suitable for construction in changing environments and have strong adaptability. As disaster relief and resettlement housing, domestic post-disaster reconstruction urgently needs residential buildings with good earthquake resistance, fast installation speed, and high living comfort. Modern housing can just meet this demand. Relying on advanced design, processing, manufacturing and installation technologies, as well as moderate prices and complete housing facilities, it will play a huge role in post-disaster urban reconstruction.

Oil extraction, prospecting, well drilling, military camps, civil engineering construction, etc. require safe, economical, fast and comfortable prefabricated houses, and prefabricated integrated houses can just meet this demand. In the near future, prefabricated houses will also be built as office buildings, shops, schools, kindergartens, etc.
