Description

Technical Field

[0001] This utility model relates to the field of adjustable connection node technology, and in particular to standardized adjustable connection nodes for modular prefabricated buildings. Background Technology

[0002] In modular prefabricated building systems, connection nodes, acting as the "link" between modules, play a crucial role. Connection nodes must not only bear various loads transmitted from the modules, including vertical gravity loads, horizontal wind loads, and seismic forces, but also ensure that each module can work collaboratively under stress, functioning as a stable and reliable integrated structure. Therefore, standardized and adjustable connection nodes for modular prefabricated buildings need to be designed.

[0003] Traditional connection nodes are mostly designed as fixed structures with relatively limited installation angles and methods, making it difficult to adapt to the diverse needs of different building designs and functional uses for modular connections. When faced with complex architectural shapes or unique spatial layouts, fixed connection nodes cannot meet the flexible and varied connection requirements between modules, limiting the innovation and flexibility of architectural design. Demountable and adjustable installation angle structures give connection nodes flexibility, enabling module connections at different angles, allowing for module recombination and layout, significantly reducing the difficulty and cost of renovations, and improving the sustainability and adaptability of buildings. Furthermore, while traditional connection nodes often have relatively fixed connection methods, the interlocking connection installation structure allows for rapid interlocking of connecting steel beams with other modules, eliminating the need for complex positioning and welding operations, greatly simplifying the installation process and improving construction efficiency. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The purpose of this invention is to provide standardized adjustable connection nodes for modular prefabricated buildings. This addresses the problem mentioned in the background that traditional connection nodes are mostly designed as fixed structures with relatively simple installation angles and methods, making it difficult to adapt to the diverse needs of different building designs and functional uses for module connections. When faced with complex building shapes or special spatial layouts, fixed connection nodes cannot meet the flexible and varied connection requirements between modules, limiting the innovation and flexibility of building design. The detachable and adjustable installation angle structure gives the connection node flexibility, enabling module connections at different angles, allowing for module recombination and layout, greatly reducing the difficulty and cost of renovation, and improving the sustainability and adaptability of the building. Furthermore, the connection methods of traditional connection nodes are often relatively fixed, while the socket connection installation structure allows for the rapid socketing of connecting steel beams with other modules, eliminating the need for complex positioning and welding operations, greatly simplifying the installation process and improving construction efficiency.
