[0002] Among prefabricated buildings, steel structure prefabricated buildings have the advantages of high seismic performance, high degree of industrialized production, short construction period, energy saving and environmental protection, easy transportation, fast construction speed, light weight, smaller beam and column cross-section, and more usable area. In particular, the ductility of steel structure buildings can attenuate seismic waves and absorb more seismic energy. Under the same earthquake intensity conditions, the disaster of steel structure houses is much smaller than that of rigid concrete structure houses, which can effectively protect people's lives and property safety.

[0003] However, when the current steel structure prefabricated low-rise buildings are used in situations where they need to be put into use quickly, such as emergency rescue, they are often time-consuming and labor-intensive to produce and install due to the large number of complex assembly components. The assembly is difficult and sometimes requires guidance from professionals, which wastes labor and cannot be put into use quickly. In addition, the houses need to be prefabricated in the factory and then transported to the site for direct installation, which makes transportation difficult. One-time connections such as welding are used, which is not convenient for later maintenance and secondary use. Summary of the invention
