Description

Technical Field

[0001] This application relates to a pin joint for a box-type ring beam, belonging to the field of steel structure construction technology. Background Technology

[0002] In large-span buildings such as steel structure stadiums, the ring beam node is the core force-transmitting component connecting the radial structure of the roof and the circumferential main beam. The design must take into account structural safety, construction feasibility and economy, and solve problems such as stress concentration, large welding deformation and insufficient fatigue performance of the node.

[0003] Therefore, in order to solve the above-mentioned technical problems, it is indeed necessary to provide a box-type ring beam pin joint to overcome the defects in the prior art. Utility Model Content

[0004] The purpose of this utility model is to provide a box-type ring beam pin joint that can be applied to the roof structure of large stadiums, so as to better connect the ring beam with the radial structure and the upper and lower structures, realize the reliable transmission of force, and ensure the stability and safety of the structure.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a box-type ring beam pin joint, including a box body, a bracket at the bottom of the box body, and several pin plates installed around the box body. The pin plates are provided with pin holes for installing pins. The pin plates include a first pin plate, a second pin plate, and two third pin plates. The first pin plate is inserted into the box body, the second pin plate is installed outside the box body, and the second pin plate is coaxial with the first pin plate. The two third pin plates are installed on the side of the bracket away from the second pin plate, and the two third pin plates are coaxial with each other.

[0006] By adopting the above technical solutions, the two sides of the box can be connected to the circumferential beam structure, and the brackets can be connected to the vertical structure. With the box as the main body, stress can be better dispersed, improving the structural bearing capacity and durability. It has high bending and torsional resistance. The sequential assembly ensures the full penetration requirement of the weld between the pin plate and the reinforcing plate, so that the force can be effectively transmitted. The pin plate and the box are at a certain angle, so that the radial and oblique connections are mainly flexible hinges, which can adapt to displacement and reduce constraints.

[0007] The pin joint of the box-type ring beam of this utility model is further configured as follows: the pin plate includes an angular plate and an insertion plate, the angular plate has two pin holes, and the insertion plate is located inside the box.

[0008] By adopting the above technical solution, the through-hole design of the insert plate ensures the stability of the structure.

[0009] The pin joint of the box-type ring beam of this utility model is further configured as follows: the pin plate includes an angular plate and a connecting block, the angular plate has two pin holes, and the connecting block is attached to the outer wall of the box body.

[0010] By adopting the above technical solution, two pins can be connected on a single spherical plate.

[0011] The pin joint of the box-type ring beam of this utility model is further configured such that: a reinforcing plate is installed on both the front and rear sides of the pin hole, and the center of the reinforcing plate is aligned with the center of the pin hole.

[0012] By adopting the above technical solution, the reinforcing plate can increase the structural strength of the pin hole.

[0013] The pin joint of the box-type ring beam of this utility model is further configured such that the bottom of the insertion plate extends out of the outer side of the box body.

[0014] By adopting the above technical solution, space is left at the bottom of the insertion plate for installing the reinforcing plate.

[0015] The pin joint of the box-type ring beam of this utility model is further configured as follows: a number of reinforcing plates 1 are connected between pin plate 1 and pin plate 2, and a number of reinforcing plates 2 are connected between two pin plates 3.

[0016] The pin joint of the box-type ring beam of this utility model is further configured as follows: several support plates are installed inside the box, and one side of the support plate passes through the box.

[0017] By adopting the above technical solution, the welding between the support plate and the box body is facilitated, making the connection tighter.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The box-type ring beam pin joint box in this utility model can connect to the circumferential beam structure on both sides, and the corbel can connect to the vertical structure, which can better disperse stress, improve the structural bearing capacity and durability, and has high bending and torsional resistance.

[0020] 2. The sequential assembly of the pin joint of the box-type ring beam in this utility model ensures the full penetration requirement of the weld between the pin plate and the reinforcing plate, enabling the force to be effectively transmitted.

[0021] 3. In this utility model, the pin plate of the pin joint of the box-type ring beam is at a certain angle to the box body, so that the radial and oblique connections are mainly flexible hinges, which can adapt to displacement and reduce constraints. Attached Figure Description

Two support plates 51 are installed inside the box body. In this embodiment, the support plates 51 pass through a top plate 61 and a long side plate 31, facilitating welding the support plates 51 into the box body. Two brackets 81 are installed at the bottom of the bottom plate 41. A groove 26 is provided on the pin plate 21 to mate with the long side plate 31. The groove 26 is located between the U-shaped plate 22 and the insertion plate 23. The long side plate 31 is fully penetrated welded to the pin plate 21 through the groove 26. There is a certain angle between the pin plate 21 and the long side plate 31. The bottom plate 41 is assembled from two right-angled trapezoidal plates 41. The inclined surfaces of the two right-angled trapezoidal plates 41 are fully penetrated welded to both sides of the insertion plate 23. The insertion plate 23 extends beyond the top plate 61 and the long side plate 31, facilitating welding between the insertion plate 23 and the box body.
