At present, the building industry in China is in a high-speed development period, and the annual increment of house construction becomes the first world. Meanwhile, the building energy consumption of China is increased to about 33% of the total social energy consumption, and the problems of building energy consumption and environmental pollution are more and more concerned by people. At present, domestic buildings are built by adopting traditional extensive and labor-intensive manual building production modes, and the building has the characteristics of long construction period, high energy consumption, great environmental pollution and low efficiency, and the quality and performance of the buildings are difficult to guarantee due to the uneven technical level of building workers, so that the building is not in accordance with the national development concept of 'green buildings'.
Therefore, the modular building as a novel assembly type building structure system has the advantages of high construction speed, small environmental pollution, easy quality guarantee and the like. In the last fifty years, the technology and market of the modular house of the buildings in the United states, Japan, Europe and the like are relatively perfect, and the modular house is a necessary living, working and residential building for people. With the rapid development of society in recent years, the living standard of people is improved, the building mode is changed silently, the requirements of people on buildings do not pay attention to the overall structural performance of the house any more, and the requirements on the quality and the speed of building construction are higher.
