Description

Technical Field

[0001] The utility model relates to the technical field of modular steel frame structures, in particular to a fully bolted H-shaped steel modular steel frame connection node. Background Art

[0002] Modular steel-frame buildings offer advantages such as high integration, rapid construction, flexible spatial layout, and minimal environmental impact. Modular buildings are composed of multiple modules, which are prefabricated in factories as complete unit structures. Typically, all internal mechanical, electrical, plumbing, and decorative work is completed in the factory before being transported to the construction site for on-site connection and assembly. Approximately 85% to 90% of modular construction occurs off-site, with the remaining work, such as foundation construction and inter-module connections, completed on-site. Modular steel frames offer significant advantages in improving construction efficiency and reducing resource consumption. Modular steel frame structures are different from ordinary steel frames. Connections need to be made between left and right modules, and between upper and lower modules. The existing connection method between modules of H-shaped steel modular steel frames requires high-precision manufacturing and installation construction deviations. Hand holes need to be opened in the web of the H-shaped steel columns to meet the connection construction requirements. The upper and lower columns are hinged and cannot transmit bending moments. Therefore, there is an urgent need for a fully bolted H-shaped steel modular steel frame connection node that can simultaneously connect the upper and lower, left and right H-shaped steel modular frame connection nodes, so that the node can not only withstand shear and axial forces, but also effectively transmit bending moments.
