Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bending-resistant joints, in particular to a bending-resistant joint between a steel beam and a box column. Background Technique
[0002] The box column gets its name because its shape is like a large iron box. Generally, it is used as a beam or column in steel structures. The box column is a slender column with a rectangular or square cross-sectional shape and gets its name because its structural shape is similar to a box. The box column is usually used to support the steel structure roof and has the advantages of light weight, high rigidity, good seismic performance, etc., so it has been widely used in modern construction projects. The I-beam is also called a steel beam and is a long steel bar with an I-shaped cross-section. The I-beam is divided into ordinary I-beams and light I-beams, which are steel sections with an I-shaped cross-section. Whether the I-shaped steel is ordinary or light, due to its relatively high and narrow cross-sectional dimensions, the moment of inertia of the two main axes of the cross-section differs greatly, so it can only be directly used for components that are bent in the plane of its web or to form lattice-type stressed components.
[0003] In the prior art, when connecting a steel beam and a box column, a connecting plate is first vertically welded on one side of the box column, and then the steel beam is connected through the connecting holes and bolts on one side of the connecting plate. Then, the steel beam and the box column are welded. However, a single connecting plate can only provide vertical support. When the lateral force is large, the lateral support at the connection of the connecting plate is relatively limited, so that the lateral force between the steel beam and the box column depends on welding support, and the reliability needs to be improved.

[0026] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects: By providing the box column body 1, when the user needs to connect the box column body 1 and the steel beam body 2, then, by providing the connecting plate 3, the connecting plate 3 is welded on both sides of the box column body 1. By providing the fixing groove 23, the user can weld between the inner wall of the fixing groove 23 and the box column body 1 with a welding rod. Compared with the method of directly welding without providing the fixing groove 23, the inclined surface of the fixing groove 23 increases the post-welding connection area, making the connection between the connecting plate 3 and the box column body 1 more firm. Thus, after welding the two connecting plates 3, the steel beam body 2 is moved so that it is inserted into the gap between the two connecting plates 3. Then, the first bolt 7 is picked up and inserted into the first connection hole 6 and the third fixing hole 13, and the third nut 27 is connected to the first bolt 7 to fix the steel beam body 2. By providing the connecting plate 3, the first bolt 7, the first connection hole 6, the third nut 27, etc., the steel beam body 2 is fixed. Then, by providing the transverse reinforcing frame 4, the transverse reinforcing frame 4 is picked up, so that the transverse reinforcing frame 4 drives the second limiting plate 16 to be inserted into the second limiting groove 17. Then, by providing the second limiting groove 17, the second limiting plate 16 is limited, thereby connecting the transverse reinforcing frame 4 and the connecting plate 3 together. Then, by providing the longitudinal reinforcing frame 5, the longitudinal reinforcing frame 5 is picked up, so that the first limiting groove 14 provided on one side is sleeved with the first limiting plate 15, thereby connecting the longitudinal reinforcing frame 5 and the transverse reinforcing frame 4. Then, by providing the second bolt 11, the user inserts the second bolt 11 into the second connection hole 10, the first fixing hole 8, and the second fixing hole 9 in sequence, and connects the first nut 12 to the second bolt 11 to fix the steel beam body 2, the longitudinal reinforcing frame 5, and the transverse reinforcing frame 4. Then, by providing the third bolt 20, the user inserts the third bolt 20 into the fourth fixing hole 19 and the first support hole 22, and connects the second nut 21 to the third bolt 20, so that the reinforcing plate 18 and the transverse reinforcing frame 4 are connected by the third bolt 20, and the longitudinal reinforcing frame 5 and the transverse reinforcing frame 4 are connected. Thus, after connection, the user can weld between the box column body 1, the longitudinal reinforcing frame 5, and the transverse reinforcing frame 4 with a welding rod, so that the transverse reinforcing frame 4 and the longitudinal reinforcing frame 5 are welded on the box column body 1. Thus, the longitudinal reinforcing frame 5 provides strengthening support for the top and bottom surfaces of the steel beam body 2. When the steel beam body 2 undergoes longitudinal bending, the side surface of the longitudinal reinforcing frame 5 is triangular and has excellent stability, so that it can provide strengthening support for the connection between the box column body 1 and the steel beam body 2. Similarly, when the steel beam body 2 undergoes transverse bending, the connecting plate 3 can provide transverse strengthening support for the steel beam body 2, so that the connection between the box column body 1 and the steel beam body 2 can resist relatively large transverse and longitudinal bending forces.Thus, the effect of connecting the box column body 1 and the steel beam body 2 is achieved comprehensively, so that the longitudinal stiffening frame 5, the transverse stiffening frame 4 and the connecting plate 3 provide strong support for the transverse and longitudinal directions of the steel beam body 2. The multiple reinforcements enable the box column body 1 and the steel beam body 2 to be stressed in multiple directions while ensuring the support and fixation effect, resulting in a better bending resistance effect and ensuring the reliability of the connection, which is relatively practical.
