Description

TECHNICAL FIELD

[0002] Modular building is a new type of building structure, which is formed by assembling the module units manufactured in the factory at the construction site like "building blocks". Modular building has the advantages of short construction period, high building quality, green low-carbon environmental protection and the like, and can meet the needs of modern buildings, and is one of the important directions of future building development.

[0003] With the increasing application of modular building, the research on modular building at home and abroad is also more and more rich. Since the seismic performance of full modular building is poor, some engineers propose to combine the module unit with various lateral force resisting systems to form a composite modular structure system. For example, the shear wall is embedded in the module during the production of the module to increase the lateral resistance of the module.

[0004] However, the lateral force resisting structure part of the existing building module and the lateral stiffness of the building function module part are quite different, therefore, the connection design between the lateral force resisting system and the main body of the module unit has an important influence on the lateral resistance and energy dissipation performance of the overall structure. Moreover, the current module unit is complex to operate when connected, and the structure is complex and difficult to operate when the building module is installed, and the lateral force resisting strength of the building module is also low. Therefore, although many scholars and engineers at home and abroad are actively developing module units with different forms of connection, but overall, it still cannot meet the requirements of simple operation, high energy dissipation and high lateral performance of the overall structure.

[0038] Specifically, if Figure 1 As shown, the two shear wall bodies 2 are mirror-symmetrically embedded in the rectangular frame 1 and the tops and bottoms of the two shear wall bodies 2 are respectively connected to the top beam 11 and the bottom beam 13 located on the long side of the rectangular frame 1; the top beam 11 located on the long side includes a plurality of first sub-top beams 11 connected end to end, and the bottom beam 13 located on the long side includes a plurality of first sub-bottom beams 13 connected end to end, and the two ends of the first sub-top beam 11 located in the middle are connected to the two adjacent first sub-top beams 11 through the top beam 11 connection box, and the two ends of the first sub-bottom beam 13 located in the middle are connected to the two adjacent first sub-bottom beams 13 through the bottom beam 13 connection box, and the top wall and the bottom wall at the edge of the shear wall body 2 are fixedly connected to the top beam 11 connection box and the bottom beam 13 connection box respectively. By setting the top beam 11 connection box and the bottom beam 13 connection box, it is possible to connect the shear wall body 2 with multiple top beams 11 and multiple bottom beams 13, thereby forming a modular unit with high lateral resistance and high energy consumption. Moreover, the top beam 11 connection box and the bottom beam 13 connection box can also improve the connection between multiple top beams 11 and multiple bottom beams 13 and the shear wall body 2, making the connection more firm and stable; and, by fixing the top and bottom walls at the edges of the shear wall body 2 to the top walls and bottom walls of the top beam 11 connection box and the bottom beam 13 connection box respectively, it is possible to achieve continuous force transmission, thereby making the modular building unit have high lateral resistance and improved energy consumption.
