[0002] With the development of modular building construction technology, more and more buildings are constructed using building modules. In the prior art, modular buildings are generally assembled using prefabricated module units, such as the building modules disclosed in CN104088366A. During assembly, after two module units are assembled, they are poured at their assembly points to connect them as a whole. When the above connection method is adopted, there are two wall panels at the assembly point, and the pouring structure will make the wall thickness at the assembly point far exceed the thickness of the normal wall, resulting in extremely serious material waste. Since the specifications of the module units are generally relatively fixed, if wall panels of different thicknesses are used according to the different locations of the module units, it will not only increase the production cost but also reduce the construction efficiency, which will reduce the advantages of modular buildings and cause the existing modular buildings to be unable to effectively balance the construction efficiency and construction cost.
