However, the prefabricated reinforced concrete box-type house currently often used, i.e. the top floor slab and the wall on four sides are integrally poured into box-type module in factory, and then transported to site for assembly, usually encounters several key common problems: first, the self-weight of single module is too large, usually more than twenty tons, and large lifting equipment is needed to meet the module production and installation requirements, however, the rent of large lifting equipment is expensive, which undoubtedly increases the construction cost. In addition, large components are more prone to cracking, honeycomb and other quality problems in production process. Second, the super heavy and super large module puts forward higher requirements for transportation road, such as road width, passing height, bearing capacity, etc., and it is difficult to meet the transportation requirements for part of rural roads and remote mountainous areas, and the application range is greatly limited. Third, there is lack of effective connection structure between modules, and most of the fabricated modular houses are simply spliced and stacked together, without any effective connection or only temporarily welded and fixed by several steel plates, and the house structure has poor integrity, which cannot guarantee the seismic performance and structural safety of the house. Fourth, the lack of effective connection between modules also easily leads to uneven settlement and even inclination between modules, and the house is prone to cracks, leakage, poor sound insulation and other quality problems in later period.
