Detailed Embodiments

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0021] This application provides a socket-type steel structure beam-column connection structure, mainly used to solve the problem that the connection strength is not high when connecting by welding or direct riveting, and the following technical solutions are provided, which will be described in detail below:

[0022] Embodiment 1:

[0023] As Figure 1 , Figure 2 , Figure 3 , Figure 4 shown, in some embodiments, it includes a cross beam 1. A fixing plate 2 is provided in the middle of the cross beam 1. A longitudinal support beam 3 is provided on the side of the fixing plate 2. A connecting mechanism 4 is provided at the connection between the fixing plate 2 and the longitudinal support beam 3. A reinforcing mechanism 5 for strengthening the connection is provided at the upper and lower connections between the cross beam 1 and the longitudinal support beam 3; The fixing plate 2 and the cross beam 1 are fixedly connected by welding; The connecting mechanism 4 includes a first connecting plate 401 and a second connecting plate 402 placed on both sides of the fixing plate 2. A plurality of connecting holes 403 are symmetrically formed on both the first connecting plate 401 and the second connecting plate 402. A connecting bolt 404 is inserted into the connecting hole 403 on the first connecting plate 401. One side of the connecting bolt 404 penetrates through the fixing plate 2 and the other side of the connecting bolt 404 penetrates through the longitudinal support beam 3; A flat washer 405 is sleeved on the other end of the connecting bolt 404, and a connecting nut 406 is threadedly connected to the other end of the connecting bolt 404; The lengths of the first connecting plate 401 and the second connecting plate 402 are both equal to the length inside the cross beam 1.

[0024] Specifically: By providing the fixing plate 2 in the middle of the cross beam 1, a stable foundation is provided for connecting the longitudinal support beam 3; The presence of the fixing plate 2 enhances the support capacity of the cross beam 1 and the stability of the overall structure; The connecting mechanism 4 is located at the connection between the fixing plate 2 and the longitudinal support beam 3 and is used to ensure a firm connection between them, which can provide a reliable structural connection and prevent loosening or detachment at the connection; The reinforcing mechanism 5 is located at the upper and lower connections between the cross beam 1 and the longitudinal support beam 3 and is used to reinforce and enhance the stability of the connection point. Through the setting of the reinforcing mechanism 5, it can effectively prevent loosening or deformation of the connection due to the load, improving the reliability and safety of the connection.

[0025] The working principle here is as follows: First, the fixed plate 2 is welded to the cross beam 1 to ensure a firm connection between the two; then one end of the longitudinal support beam 3 is attached to the side of the fixed plate 2, and the first connecting plate 401 and the second connecting plate 402 are respectively placed on both sides of the fixed plate 2 and connected to the fixed plate 2 through the connecting holes 403; the connecting bolts 404 are inserted into the connecting holes 403 on the first connecting plate 401 and the second connecting plate 402, with one side of the connecting bolts 404 passing through the fixed plate 2 and the other side passing through the longitudinal support beam 3. When it is not smooth for the connecting bolts 404 to pass through the first connecting plate 401, the fixed plate 2 or the longitudinal support beam 3 and the second connecting plate 402, a pointed crowbar can be used to continuously dredge the connecting holes 403 to ensure that the connecting bolts 404 can freely pass through the connecting holes 403, and all directions of the connecting bolts 404 are the same, all entering from one direction. Then, the flat washers 405 are placed at the other end of the connecting bolts 404, and the connecting bolts 404 are initially tightened by hand first, and finally, a power wrench is used for final tightening, tightening from the bottom up and from the middle to the surrounding to spread the slack gap from the middle to the surrounding. Through this connection method, a firm connection structure is formed among the fixed plate 2, the longitudinal support beam 3 and the cross beam 1, which can effectively bear the load and provide stable support. The reinforcement mechanism 5 is located at the upper and lower connection parts of the cross beam 1 and the longitudinal support beam 3 and is used to reinforce and enhance the stability of the connection points. Through the setting of the reinforcement mechanism 5, it can effectively prevent the connection points from loosening or deforming due to bearing the load, improving the reliability and safety of the connection. The connecting plates with equal lengths are respectively located on both sides of the fixed plate 2, which can provide uniform supporting force, enabling the cross beam 1 to receive uniform force distribution and reducing the possibility of local stress concentration, thereby improving the stability and reliability of the overall structure. It should be noted that: The first connecting plate 401 and the second connecting plate 402 are made of steel with a thickness of 16 mm, the diameter of the connecting hole 403 is 22 mm, and the diameter of the inserted connecting bolt 404 is 20 mm with a strength of Q355; the connecting bolts 404 and the gaskets need to be phosphated to prevent the connecting bolts 404 and the gaskets from rusting and improve their durability.

Reinforcement bolts 502 are symmetrically and threadedly connected to the reinforcement plate 501. The other end of one of the reinforcement bolts 502 acts on the cross beam 1 and the other end of the other reinforcement bolt 502 acts on the longitudinal support beam 3. Both sides of the reinforcement plate 501 are fixedly connected by welding. Both ends of the upper and lower connection parts of the cross beam 1 and the longitudinal support beam 3 are fixedly connected by welding. The working principle here is as follows: The reinforcement plate 501 is placed in the middle of the upper and lower connection parts of the cross beam 1 and the longitudinal support beam 3, and the reinforcement bolts 502 are symmetrically and threadedly connected. Through welding, both sides of the reinforcement plate 501 are fixedly connected to the cross beam 1 and the longitudinal support beam 3, thereby strengthening the connection between them. Similarly, both ends of the upper and lower connection parts of the cross beam 1 and the longitudinal support beam 3 are also fixedly connected by welding, ensuring the stability and firmness of the overall structure. It should be noted that it is commonly used for steel structure connection, is easy to install and fasten, and is usually used in conjunction with hex nuts and washers to increase the stability and fastening force of the connection.
