Description

Technical Field

[0001] The utility model relates to the technical field of steel structure modular buildings, in particular to a self-buckled grouting connection structure used for steel structure modular buildings. Background Art

[0002] As a highly integrated building system, steel structure modular buildings are increasingly gaining widespread attention and application. They combine steel structure with modular design to achieve a fast, efficient and sustainable construction method. Thanks to modern industrial technology, about 90% of the processes of steel structure modular houses have been prefabricated in factories, including the main steel structure frame, water and electricity pipelines, and decoration. After being transported to the construction site, various combinations are completed through the connection of the main module nodes to achieve the use functions and requirements of the building.

[0003] The connection nodes between the main modules are the key to the steel structure modular building to transfer the upper load and coordinate the deformation between the unit modules, and play a vital role in the overall stability of the main structure. The design of the connection nodes must take into account the operability and error control during the module assembly process while meeting the stiffness and strength requirements of the structure.

[0004] Traditional connection nodes are not fixed during the installation process, which makes it difficult to accurately position the connection parts when hoisting the upper modules, which easily leads to the accumulation of multi-dimensional construction errors during the installation process. Reliable connection nodes are the key to ensuring the overall stability and safety of modular buildings, and are also one of the main factors that fully reflect the advantages of steel structure modular buildings.
