Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of prefabricated buildings, and in particular to an optimized module structure system and installation process. Background Art
[0002] Modular construction is an emerging building structure system that uses each room as a modular unit, which is prefabricated in a factory, transported to the site, and assembled into a whole building through reliable connections.
[0003] Each module unit is a rectangular module composed of four corner columns, four bottom beams and four top beams. The upper and lower module units are connected by rigid connection of columns, and the top beams and bottom beams between the upper and lower module units work independently.
[0004] From the above-mentioned characteristics of modular buildings, it can be seen that the stiffness of the columns of modular buildings is easily caused to be significantly smaller than the strength and stiffness of the long side bottom beams. This beam-column relationship is not conducive to the seismic ductility design of the structure, because the beams in the seismic performance frame should yield before the columns, and plastic hinges appear in the beams to dissipate seismic energy. The nature of strong beams and weak columns in modular buildings will cause the columns to be destroyed first before the beams dissipate seismic energy under the action of an earthquake, which is not conducive to the seismic resistance of the structure.
[0005] The bottom beam and top beam work independently. In order to ensure the strength and rigidity of the beam, the cross-sectional size is selected to be larger, and the amount of steel and cost are both high. In addition, the top beam and bottom beam of the upper and lower module units constitute the space occupied by the module beam structure, which is significantly higher than the height of the ordinary frame structure beam. The height of each floor can differ by more than 0.18m. The height of a twenty-story building differs by 3.6m, which is equivalent to the height of one floor. The more floors there are, the greater the cumulative height, which is obviously not economical.
[0006] The upper and lower columns between floors are rigidly connected. In modular buildings, the structure that has completed some internal and external decoration reduces the operability on site, and the building modules are hoisted one by one during the installation process, further obscuring the on-site construction connection space, making it difficult to achieve rigid connection of the columns; if construction holes are left for on-site connection, the on-site work of closing the holes will reduce the quality of the finished building.
[0007] Based on the above problems, how to optimize the existing modular buildings is an urgent problem to be solved. Summary of the invention

[0016] The module structure system optimized by the present invention is further connected between the fixing member and the slider via a spring, one end of the spring is connected to the insertion end of the slider, and the other end is connected to the fixing member, and the spring is in a stretched state after the slider slides out of the socket and is in a natural state after being inserted into the socket; A positioning hole is provided at the bottom of the slider, and a spring self-locking pin is provided on the fixing member.
