Description

Technical Field

[0001] This utility model relates to the field of steel structure connection, specifically a steel structure connection device for office buildings. Background Technology

[0002] Modular steel structures are a highly integrated building structure system, representing an advanced stage in the development of industrialized construction. Using factory prefabrication, modular steel structures divide buildings into room-based modular units, each integrating structural components, enclosure components, building equipment, and interior finishes. These buildings are characterized by their lightweight, energy efficiency, environmental friendliness, rapid construction, and high degree of industrialization. Furthermore, the reusability of steel reduces construction waste, making them more environmentally friendly and widely used in both industrial and residential buildings.

[0003] Nodes are a key element in the design of modular steel structure buildings, and their reliability plays a crucial role in the overall safety of the module. Once a node connection fails, the structure cannot function properly. Therefore, the design and construction of nodes are extremely critical. Currently, most modular steel structure modules use welded connections. Welded connections require on-site construction, are easily affected by the site environment, and the welding quality is highly dependent on the skill level of the welders. Under seismic loading, welded connections often suffer brittle failure due to weld fracture.

[0004] In response to this problem, products such as:

[0005] 1) CN118087716A discloses a modular steel structure detachable energy-dissipating connection node. In this application, the node includes a cross-shaped connector, modular beams, and modular columns. The cross-shaped connector includes a horizontal plate and a vertical plate connected vertically to the middle of the horizontal plate. The modular beam includes an H-beam, a vertically extending end plate, and stiffening ribs connecting the H-beam and the extending end plate. The extending end plate connected to the stiffening ribs has pre-drilled holes for the first horizontal bolts. The modular column uses rectangular steel pipes, with an upper inner diaphragm corresponding to the upper flange of the H-beam and a lower inner diaphragm corresponding to the lower flange. Four sets of modular units are arranged at the angle between the horizontal and vertical plates of the cross-shaped connector. This node uses a fully bolted connection to form a semi-rigid node, with clear force transmission and reliable connection. Because the extending end plate has good deformation and energy dissipation capabilities, it enhances the node's seismic resistance, meets the design principle of "strong node, weak component," and improves the node's seismic performance.

[0006] 2) CN211816926U discloses a steel beam-column cross-shaped node connection structure. In this application, the connection structure includes three H-shaped steel beams, four connectors, bolts, and a steel square tube column. The H-shaped steel beams include an upper flange plate, a lower flange plate, and a web plate. The connectors include an upper connecting plate, a lower connecting plate, a large web plate, and a small web plate. The upper and lower connecting plates are perpendicularly connected to the large and small web plates, and the large and small web plates are also perpendicularly connected to each other. The upper, lower, large, and small web plates form a shovel-shaped, scoop-like structure. The three H-shaped steel beams are arranged in a cross shape. The steel square tube column includes a fixedly connected upper end plate, a lower end plate, and a column body, and is connected below and / or above the H-shaped steel beams. This utility model requires only four standardized components to complete the assembly of the steel beam-column cross-shaped node connection structure. The structure is robust, highly practical, and meets the needs of modern prefabricated buildings for convenient, quick, and environmentally friendly installation.

[0007] However, the aforementioned existing technologies are all for connecting steel components in the X and Y directions. Some connection nodes in steel structures require connecting components in the X, Y, and Z directions, so the aforementioned existing technologies cannot meet the requirements. Utility Model Content
