Description

[0002] The traditional house construction process takes a lot of time, manpower and material resources, and often damages the environment, so people have been looking for more efficient and environmentally friendly construction methods. In recent years, with the continuous development of modular house technology, more and more countries have begun to promote the use of modular houses. At present, the development of modular houses is an effective measure to achieve energy conservation and environmental protection, improve the quality of construction, and achieve upgrading of the construction industry.

[0003] In the market, the mainstream modular houses are mainly modular concrete houses and steel structure modular houses. For modular concrete houses, modular concrete shear wall structures and modular concrete frame structures are the main ones. Among them, the load-bearing components of steel structure modular houses are all steel structures, which are relatively poor in comfort, and the price of steel is relatively high, which is greatly affected by market fluctuations. Due to the characteristics of steel, its application in single-layer and small spans is limited. Since the construction method is similar to the traditional prefabricated type, after a wall panel is hoisted, it is necessary to add diagonal supports on the side of the wall panel, which will lead to problems such as chaotic internal space occupation and numerous diagonal supports in the construction of modular houses, affecting the construction speed and convenience.
