Description

Technical Field

[0001] This utility model relates to the field of steel structure node technology, specifically a steel structure beam-column node reinforcement connection structure. Background Technology

[0002] Steel structures have a series of advantages such as high strength, light weight, fast construction speed, low foundation cost, small footprint, high degree of industrialization, and beautiful appearance. With the development of my country's economy and the enhancement of its comprehensive strength, steel structure buildings have developed rapidly. In the construction of steel structure buildings, the beam-column joints of steel structures have a significant impact on structural force transmission, project cost, and construction difficulty.

[0003] Chinese patent application CN111827475A discloses a reinforced prefabricated steel structure beam-column joint. This joint utilizes a rational arrangement of inverted L-shaped lugs on the column flanges, which are embedded and connected to the beam end plates. Prefabricated in a factory, it allows for easy placement during on-site assembly, eliminating the need for welding and resulting in high construction efficiency and safety. However, since prefabricated steel structures typically use I-beams for both columns and beams, the inverted L-shaped lugs, fixed to one flange of the I-beam, inevitably lead to significant localized stress on that flange. This prevents the beam from effectively transmitting force with the entire I-beam, resulting in poor seismic performance and certain usability defects. Furthermore, the prefabricated welding between the inverted L-shaped lugs and the column flanges makes them susceptible to deformation during transportation, hindering later assembly and fixation with the beam. Therefore, this case arose from in-depth research into these issues. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel structure beam-column joint reinforcement connection structure, comprising an H-shaped steel column and an H-shaped steel beam. Z-shaped buckles are symmetrically arranged on the flange of the H-shaped steel column near the H-shaped steel beam. The Z-shaped buckles are fixed to the flange of the H-shaped steel column by reinforcing connectors. An end plate is welded to one end of the H-shaped steel beam. The end plate is inserted between the Z-shaped buckles and the flange of the H-shaped steel column and is assembled and connected to the Z-shaped buckles and the flange of the H-shaped steel column by bolt fasteners.

[0006] The aforementioned reinforcing connectors include U-shaped reinforcing buckles, which are fastened to the outside of H-shaped steel columns and Z-shaped buckles. Assembly holes are provided at both ends of the U-shaped reinforcing buckles, the flanges of the H-shaped steel columns, and the corresponding positions on the Z-shaped buckles. Long bolts are inserted into the assembly holes, and the exposed ends of the long bolts are locked with nuts.

[0007] A reinforcing plate is welded to one end of the Z-shaped buckle plate, and a reinforcing rib is welded between the reinforcing plate and the side wall of the Z-shaped buckle plate. The reinforcing plate is connected and fixed to the wing plate of the H-shaped steel beam by bolt fasteners.

[0008] The aforementioned H-shaped steel columns have transverse stiffening ribs welded between their flanges.
