Description

Technical Field

[0001] This utility model relates to the field of bridge node connection technology, and more specifically, to a bridge node connection structure. Background Technology

[0002] In the field of bridge engineering construction, the node connection structure, as the core and key part of the bridge load-bearing system, directly determines the overall load-bearing performance, stability and service life of the bridge.

[0003] A search revealed a Chinese patent application with patent number CN202021860056.1, which discloses a steel structure bridge node connection structure, including a vertical beam, a first horizontal beam, and a second horizontal beam. The vertical beam has a convex groove and a concave groove on its left and right sides, respectively, and the convex groove and concave groove match. The vertical beam also has two stop blocks. The right end of the first horizontal beam has a convex block, and the left end of the second horizontal beam has a concave block. The contact part between the convex block and the concave block is provided with a first fixing bolt. Support members are provided on the lower side of both the first horizontal beam and the second horizontal beam. This utility model solves the problem that in the conventional bolt connection method, bolts are needed to fix the horizontal beam on both sides of the vertical beam. The number of bolts required for the connection is large, and because the horizontal beams are fixed separately on both sides of the vertical beam, the stress at the connection is relatively concentrated when the horizontal beam is under load, which affects the stability of the connection and is prone to deformation of the steel structure at the connection. Although the above-mentioned patent can achieve the detection function, it still has the following shortcomings in use: the connection structure in the prior art can only connect the horizontal beam and the vertical beam. Its connection mechanism is inconvenient to adjust the angle and connect the inclined beam and the vertical beam. It has poor flexibility. At the same time, the connection structure in the prior art requires a specific number to be matched for installation, which has poor versatility. Utility Model Content

An installation sleeve is fixedly connected to the outer end of the rotating block. A side beam is inserted into the installation sleeve. The side beam is fixedly connected to the installation sleeve by a bolt assembly. An adjustable support assembly is provided on the lower end face of the installation sleeve.

[0006] As a preferred technical solution of this application, the adjustable support assembly includes a connecting seat fixed at the center of the lower end face of the mounting sleeve.

[0013] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0014] like Figures 1-5 As shown, the bridge node connection structure includes a vertical beam 1. The top of the vertical beam 1 is fixedly connected to an assembly plate 2 by a bolt assembly. Two connecting plates 3 are symmetrically and fixedly connected to the outer wall of the assembly plate 2. A rotating block 4 is rotatably connected between the two connecting plates 3. An installation sleeve 5 is fixedly connected to the outer end of the rotating block 4. A side beam 6 is inserted into the installation sleeve 5. The side beam 6 is fixedly connected to the installation sleeve 5 by a bolt assembly. An adjustable support assembly 7 is provided on the lower end face of the installation sleeve 5. The assembly plate 2 provides support for the rotation of the rotating block 4 through the connecting plates 3. The installation sleeve 5 is used to insert the side beam 6. The adjustable support assembly 7 can adjust the installation angle of the installation sleeve 5, so that the side beam 6 can be adjusted to adapt to different installation scenarios. The adjustable support assembly 7 can also further improve the structural stability.

[0015] in, like Figures 1-4As shown, the adjustable support assembly 7 includes a connecting seat 701 fixed at the center of the lower end face of the mounting sleeve 5. A first connecting head 702 is rotatably connected inside the connecting seat 701. A first threaded rod 703 is fixedly connected to the bottom end of the first connecting head 702. An assembly frame 704 is threadedly connected to the first threaded rod 703. A second threaded rod 705 is threadedly connected to the bottom end of the assembly frame 704. A second connecting head 706 is fixedly connected to the bottom end of the second threaded rod 705. A fixed seat 707 is rotatably connected to the second connecting head 706. The fixed seat 707 is fixedly connected to the vertical beam 1 by a bolt assembly. The length can be finely adjusted by the cooperation of the first threaded rod 703, the second threaded rod 705 and the assembly frame 704, thereby enabling support of the mounting sleeve 5 at different angles. This facilitates the connection of the vertical beam 1 with the horizontal beam or the diagonal beam, making it more flexible. At the same time, the first threaded rod 703, the second threaded rod 705 and the assembly frame 704 can also support the mounted sleeve 5 after installation.

[0016] To further explain, such as Figures 1-4 As shown, both the first threaded rod 703 and the second threaded rod 705 have an installation port 708, and each installation port 708 has a limiting piece 709. Each limiting piece 709 has a nut 7010 on its outer side. The nuts 7010 are threadedly connected to the first threaded rod 703 and the second threaded rod 705, respectively. By tightening the nuts 7010 to compress the limiting pieces 709, the relative rotation of the first threaded rod 703, the second threaded rod 705 and the assembly frame 704 is restricted, thereby achieving locking and fixing of the adjustable support assembly 7 after length adjustment.

[0017] like Figure 1 , Figure 4 and Figure 5 As shown, two first reinforcing blocks 8 are symmetrically and fixedly connected to the outer side wall of the connecting plate 3. The ends of the two first reinforcing blocks 8 near the assembly plate 2 are fixedly connected to the assembly plate 2. The first reinforcing blocks 8 can disperse the load of the rotating block 4 and the side beam 6 borne by the connecting plate 3, and prevent the connecting plate 3 from deforming or breaking due to stress concentration at the connection between the connecting plate 3 and the assembly plate 2.

[0018] like Figure 1 , Figure 4 and Figure 5 As shown, a second reinforcing block 9 is preferably fixedly connected between the rotating block 4 and the mounting sleeve 5. The second reinforcing block 9 is distributed on the front and rear sides of the rotating block 4. The second reinforcing block 9 strengthens the connection rigidity between the rotating block 4 and the mounting sleeve 5, disperses the torque transmitted from the side beam 6 to the rotating block 4 through the mounting sleeve 5, prevents cracking at the connection between the two, and improves the structural stability of the side beam 6 after assembly.

[0019] When using this bridge node connection structure: First, the assembly plate 2 is installed on the vertical beam 1 using bolt assemblies. Then, the nuts 7010 are rotated to release the limiting plate 709, moving the limiting plate 709 away from the mounting end of the assembly frame 704. Next, the assembly frame 704 is rotated to adjust the overall length between the assembly frame 704 and the first threaded rod 703 and the second threaded rod 705. Then, the fixing seat 707 is attached to the mounting position of the vertical beam 1. The mounting sleeve 5 and the rotating block 4 are rotated between the two connecting plates 3 by the first threaded rod 703, the second threaded rod 705, and the assembly frame 704. The angle of the mounting sleeve 5 is adjusted. Then, the fixing seat 707 is fixed to the vertical beam 1 using bolts. The side beam 6 is then inserted into the mounting sleeve 5, and the side beam 6 is fixed to the mounting sleeve 5 using bolt assemblies.
