Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of prefabricated modular construction, in particular to a module self-locking embedded connection assembly method and system. BACKGROUND

[0002] MiC is Modular Integrated Construction, also known as assembly synthesis construction method. It is a method of building by combining and installing building modules off-site and on-site through prefabricated modular production. (1) Concrete MiC generally uses post-poured grouting method to connect different prefabricated components and steel bars. The disadvantage is that wet work and steel bar binding are still required at the assembly construction site. Steel bar binding, as a labor and time-consuming work, cannot be completely transferred to the prefabricated link in the factory. Post-poured grouting also needs a certain time to form initial strength. Based on the above two points, the existing construction method based on concrete prefabricated parts cannot take advantage of the prefabricated assembly method to speed up the construction period on site, and the disadvantages of wet work, such as site cleaning, cannot be avoided by using prefabricated assembly method. Moreover, the quality of post-poured construction or bolt connection is difficult to control. (2) Steel structure MiC generally uses box-shaped foot pieces evolved from container processing to form horizontal connection by inserting shear pins and steel plates. The vertical connection between modules is generally by bolt, and there is also a post-poured grouting method. The main disadvantage of the current steel structure MiC connection method is the reliability of the bolt. During the life cycle of the main structure, with the expansion and contraction of the structure and the wind vibration deformation of the structure over the years, there are occasional cases of bolt loosening and falling. Bolt loosening and falling not only affect the safety of the overall structure, but also high-altitude falling objects are a safety hazard. For steel structures, if multiple modules are connected, such as 8 MiC modules connected horizontally and vertically, many common methods will be difficult to work and lock due to the small space.
