Description

Technical Field

[0001] The invention relates to the technical field of structural engineering, and in particular to a rapidly assembled modular structure and a building structure. Background Art

[0002] Modular buildings are a type of prefabricated building with the highest assembly rate. As the traditional load-bearing components, beams, plates, and columns are connected in advance in the factory to form space modules, the controllable production environment can greatly guarantee the quality of the modules. As space modules with self-bearing and self-stabilizing performance, the decoration process is completed in the factory, which can greatly reduce the demand for on-site labor and reduce on-site pollution. Modular buildings are an excellent choice for promoting the industrialization of buildings.

[0003] The factors that need to be considered in the application and promotion of modular buildings include the following aspects: First, the disassembled modules should have self-bearing and self-stabilizing properties, and be able to provide interior decoration carriers while meeting the lifting requirements; second, the connection between modules should be reliable, so as to form a modular structure with reasonable force and good overall performance for application in areas with seismic fortification intensity; third, reduce the module specifications to reduce the cost of modules produced by the factory assembly line, thereby reducing the cost of modular buildings. Finally, in addition to the above-mentioned bearing capacity of modular structures, the assembly of interior decoration, exterior wall decoration, and roof drainage facilities of modular buildings on modular structures has not been reported. Modular buildings are a form of construction with a very high assembly rate and have broad market application prospects.

[0004] The only difference between existing modular buildings and traditional buildings is that they are processed in factories to form corresponding modules, which are then transported to the construction site for use. However, they are still connected using traditional nodes, and connections in multiple directions need to be considered. Summary of the invention
