Abstract
Description
Technical Field
[0001] This utility model belongs to the field of steel structure technology, and specifically relates to a steel structure corner brace connection structure. Background Technology
[0002] The market prospects for steel structures are very broad, especially in green building and new urbanization construction. Steel structures have been widely used and promoted due to their advantages such as environmental protection, energy saving, and fast construction speed. Secondly, market demand is constantly increasing. With the acceleration of infrastructure construction and the advancement of urbanization, the demand for steel structures in bridges, building construction, and other fields has increased significantly. In addition, the construction of power systems, such as thermal power plants, nuclear power plants, and wind power generation, will also drive the growth of steel structure demand. Finally, technological innovation and intelligent construction have brought new development opportunities to the steel structure market. With the application of advanced technologies such as BIM and 3D printing, the design, manufacturing, and construction efficiency of steel structure buildings has been greatly improved, further promoting its application in high-end manufacturing and specialized fields.
[0003] The supporting rods installed between steel structure beams and columns, beams and purlins, and columns and purlins are called corner braces, such as... Figure 1 As shown, existing corner brace connection structures are generally connected to beams or columns using high-strength bolts or welding. Welded connections have the following problems: large on-site welding workload, high precision requirements, and long construction period; unclear force transmission path, easily leading to localized stress concentration; and inconvenient later inspection or replacement of welded joints. Corner braces are generally prefabricated in the factory. High-strength bolt connections are prone to problems such as inconvenience in installation or inconsistent tightness due to differences in the manufacturing precision of the mounting holes (conventional high-strength bolt mounting holes are round) and the corner brace, resulting in poor stability and affecting the strength of the steel structure. Summary of the Invention
[0004] To address the aforementioned problems in the existing technology, this utility model provides a steel structure corner brace connection structure.
[0005] The purpose of this utility model is achieved in the following manner: a steel structure corner brace connection structure, including steel columns and H-shaped steel beams connected to the steel columns, corner braces are set between two adjacent H-shaped steel beams, and a connecting plate is connected to each end of the corner brace by high-strength bolts. The other end of the connecting plate is connected to the flange plate of the H-shaped steel beam by a sliding groove connector and high-strength bolts. The sliding groove connector includes a bottom edge, two side edges, and two short sides formed by bending the two side edges towards the middle. The flange plate of the H-shaped steel beam is connected to the bottom edge of the sliding groove connector by high-strength bolts. There is a gap between the two short sides of the sliding groove connector for the high-strength bolts to pass through. A baffle with threaded holes is set below the two short sides. The end of the connecting plate is connected to the sliding groove connector by high-strength bolts and baffles.
[0006] The two short sides of the slide connector are bent downwards to form a bend parallel to the side, and the baffle is located below the bend.
[0007] Anti-slip grooves are provided at the end of the bent part that contacts the baffle.
[0008] The slide rail connector is integrally formed.
[0009] The groove connector is formed by bending a U-shaped steel plate.
[0010] Compared to existing technologies, the corner brace of this utility model connects the flange plates of the H-beam through connecting plates, sliding groove connectors, and high-strength bolts. The high-strength bolt connection replaces part of the welding, reducing on-site work, enabling rapid assembly, and improving installation efficiency. The structure of the sliding groove connector allows for adjustment of construction errors and facilitates later maintenance and replacement, improving installation quality and accuracy.

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention. After reading the contents of the present invention, those skilled in the art can make various modifications or alterations to the present invention, and these equivalent forms also fall within the scope defined by the present invention.
[0014] like Figure 2 As shown, a steel structure corner brace connection structure includes a steel column 8 and an H-shaped steel beam 6 connected to the steel column. A corner brace 3 is provided between two adjacent H-shaped steel beams 6. A connecting plate 2 is connected to both ends of the corner brace 3 by high-strength bolts. The other end of the connecting plate 2 is connected to the flange plate of the H-shaped steel beam by a sliding groove connector 1 and high-strength bolts. The sliding groove connector 1 includes a bottom edge 11, two side edges 12, and two short sides 13 formed by bending the two side edges towards the middle. The flange plate of the H-shaped steel beam is connected to the bottom edge 11 of the sliding groove connector by high-strength bolts 4. There is a gap between the two short sides 13 of the sliding groove connector for the high-strength bolts to pass through. A baffle 5 with threaded holes is provided below the two short sides 13. The end of the connecting plate 2 is connected to the sliding groove connector 1 by high-strength bolts 4 and baffle 5.
[0015] The baffle 5 can slide along its length within the sliding groove connector 1, thereby facilitating the connection between the connecting plate 2 and the H-beam, adapting to larger construction errors, and making adjustment easier.
[0016] The flange plate of the H-beam is the lower flange plate of the H-beam. The baffle 5 is preferably made of steel plate or high-strength steel plate. The corner brace 3 is preferably made of angle steel.
[0017] In a further preferred embodiment, the two short sides 13 of the slide connector are bent downwards to form bends 14 parallel to the sides, with the baffle 5 located below the bends 14. In an even more preferred embodiment, anti-slip grooves (not shown in the figure) are provided at the end of the bend 14 that contacts the baffle 5. These anti-slip grooves increase the friction between the bend 14 and the baffle 5, ensuring a secure fixation. Anti-slip grooves are also provided at corresponding positions on the baffle 5 for even better anti-slip performance.
[0018] The slide rail connector 1 is integrally formed. Integral-formed components have high strength and good stability. Furthermore, the slide rail connector 1 is formed by bending a U-shaped steel plate.
