Description
Technical Field
[0001] The utility model relates to the technical field of modular buildings, in particular to a connection node between modules embedded in a main structure. Background Art
[0002] Modular construction is a new type of prefabricated construction mode with a higher degree of integration and industrialization. More than 90% of the building's structure, interior and exterior decoration, electromechanical, water supply and drainage, HVAC and other elements are automatically manufactured and systematically integrated in the factory. Only a small amount of work such as hoisting, processing the pipeline connection and decoration at the joints of the modules is required on site. On-site construction and factory production are carried out simultaneously, which can improve efficiency and quality while reducing the project construction period. The pollution such as construction waste, noise, and dust during on-site construction is also significantly reduced. It is currently the construction technology with the fastest construction speed, the highest degree of industrialization, the highest degree of integration, and the lowest waste emissions. However, the limitations of the force mode, the limitations of the module transportation height, and the problems of module renewal and reuse limit the overall height and floor height of ordinary modular buildings.
[0003] Compared with ordinary modular buildings, the emerging embedded modular buildings integrate structural, electromechanical and decorative embedded modules. The embedded modules are embedded in the main structure. The embedded modules are self-supporting and serve as additional loads for the main structure. They do not participate in sharing earthquake loads and wind loads.
[0004] At present, most of the connection nodes between modules at home and abroad are stacked box-type connection nodes, which participate in the weighing of earthquake effects, wind loads and their own loads.

Therefore, there is an urgent need for a connection node between embedded modules to solve the connection problem between embedded modules in a simple connection method. Utility Model Content
