[0002] Modular buildings can be mass-produced with high integration of space modules on the assembly line with the help of modern industrial technology, and the complete modular structure system can be formed by rapid assembly on site after the foundation engineering construction is completed. Because of the performance characteristics of high ductility, light weight, high strength, no wet operation on site of steel structure material, it is suitable for modular buildings, and the highly integrated steel modules have the advantages of fast on-site construction speed, flexible assembly, low on-site labor demand, etc., and have broad market application prospects.

[0003] The reliable connection between the stacked modules determines the overall performance and seismic resistance of the module structure. In the existing stacked module structure, the module structure is a three-dimensional space structure formed by four ceiling beams, four floor beams and four module columns, and also has a ceiling and a floor. The beams and columns in the module structure are mostly traditional I-shaped sections and square steel tube sections. When connecting the modules, especially connecting the upper and lower 4 modules and 8 modules, more operation platforms are needed. To achieve good overall performance of the stacked module structure, the upper and lower module columns need to be directly connected to transmit force in the vertical direction, and horizontal connections between modules are needed to enhance the overall structure and improve the ability to resist wind load and horizontal seismic action.

[0004] In summary, the existing stacked module structure needs to connect four traditional beams and eight traditional columns at the joint, or even eight traditional beams and sixteen traditional columns, which causes the module beams and columns to not fully utilize the material properties and increases the cost.
