Description

Technical Field

[0001] This utility model belongs to the field of building steel structure, and relates to a steel structure, and particularly to a steel structure beam and column. Background Technology

[0002] Steel structures are structures primarily composed of steel materials and are one of the main types of building structures. The structure mainly consists of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates, which are typically connected by welding, bolts, or rivets. Due to their light weight and ease of construction, they are widely used in large factories, stadiums, and high-rise buildings.

[0003] The connection between steel structure beams and columns is not stable. Although it is stably connected by bolts 3 and nuts, bolts 3 and nuts may loosen after being subjected to vibration during long-term use. This reduces the load-bearing capacity of the steel structure beams and columns at the connection. In addition, if the nuts loosen from bolts 3, it may cause the steel structure beams and columns to separate.

[0004] For example, the steel structure beam and column with application number 201420856688.9 includes channel steel 1, rib plate 2 and stiffening plate. The channel steel 1 is connected end to end by bolts 3 and nuts. The bottom surface of the channel steel 1 is fixedly connected by rib plate 2. Several stiffening plates are inserted into the channel steel 1.

[0005] The aforementioned patent uses bolts 3 and nuts for connection. After a long period of operation, the nuts and bolts 3 may loosen, which may cause the connection between the channel steels 1 to become unstable and increase safety hazards. Utility Model Content

[0021] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0022] like Figures 1 to 5 As shown, this utility model can be implemented through the following embodiments: A steel structure beam-column includes a channel steel 11 and a rib plate 22. The rib plate 22 is welded inside the channel steel 11. One end of the channel steel 11 is provided with an installation part 1111. The installation part 1111 is provided with a sliding groove 111111. The other end of the channel steel 11 is provided with a slider 1212.

A reinforcing block 1313 is provided at one end of the channel steel 11 and the slider 1212.

[0023] The slider 1212 slides into the groove 111111 and engages with the channel steel 11 through the limiting plate 121121, making the assembly between the channel steels 11 more secure; the bolt 33 is used to connect the two channel steels 11 to ensure stable connection; the reinforcing block 1313 is used to strengthen the connection of the channel steel 11 at the slider 1212 and reduce the possibility of deformation of the channel steel 11 due to the slider 1212.

[0024] like Figure 2 and Figure 3As shown, the bolt 33 has a limiting section 3131 at its end, and a limiting annular groove 311311 is formed within the limiting section 3131. A movable groove 131131 is formed within the reinforcing block 1313, and a locking block 44 is installed within the movable groove 131131. The limiting section 3131 is inserted into the reinforcing block 1313, and the limiting annular groove 311311 cooperates with the locking block 44, limiting the possibility of the bolt 33 loosening after prolonged use. The limiting annular groove 311311 also reduces machining difficulty and facilitates production.

[0025] like Figure 2 and Figure 4 As shown, the movable groove 131131 is connected to a through groove 55, and a push rod 66 is installed in the through groove 55. The locking block 44 is provided with a receiving inclined surface 4141.
