[0002] A bridge structure typically consists of two basic parts: the superstructure and the substructure. The two are connected by a bearing system to form a complete bridge system. The superstructure is the main load-bearing part of the bridge that spans obstacles. It is located above the bearings and mainly includes: the load-bearing structure, the bridge deck system, and the bearing system. The substructure is located below the bearings and its main function is to support the superstructure and transfer the load to the foundation. It includes: piers, abutments, and foundations.

[0003] The upper and lower structures of a bridge are usually connected by a specific connecting device. Existing connecting devices are usually only used to connect the upper and lower structures of a bridge. However, when a bridge encounters aftershocks, the lack of seismic isolation devices will affect the service life of the bridge. Therefore, how to provide a connecting device for the upper and lower structures of a modular bridge that is easy to assemble is a problem that urgently needs to be solved by those skilled in the art.

[0007] Furthermore, the magnetic buffer mechanism includes two magnet fixing plates, which are respectively fixed to the bottom end of the upper damping plate and the top end of the lower damping plate by multiple fixing elements. The magnet fixing plates are fixedly connected to the mounting magnets by multiple corresponding mounting holes and mounting screws.

[0008] Furthermore, the damping buffer mechanism includes a first damper fixing plate, a first damper connector, a damper, a second damper connector, a second damper fixing plate, and a spherical connecting block. Multiple spherical grooves are provided at the bottom of the upper connecting plate and the top of the lower connecting plate.

The damping buffer mechanism, magnetic buffer mechanism, and elastic buffer assembly provide three buffer structures for the connecting device, which can more efficiently buffer the impact force in the face of natural disasters such as earthquakes, ensuring the stability of the bridge.

[0016] In this embodiment, the elastic buffer assembly includes a T-shaped connecting block 6, connecting posts 7, and disc springs 8. The T-shaped connecting block 6 has multiple connecting posts 7, and multiple disc springs 8 are sleeved on the connecting posts 7. The T-shaped connecting block 6 is slidably connected to the connecting plate groove 19 provided on the upper connecting plate 1 or the lower connecting plate 4. The end of the connecting post 7 away from the T-shaped connecting block 6 extends into the guide cylindrical groove 21 of the upper damping plate 2 or the lower damping plate 3. The multiple disc springs 8 are arranged in pairs opposite each other to improve the elastic effect of the disc springs 8. Simultaneously, during use... Figure 2 The T-shaped connecting block 6 shown can descend at the connecting plate groove 19 to allow the connecting column 7 to sink into the guide cylindrical groove 21 to guide the T-shaped connecting block 6, while facilitating the installation and disassembly of the overall structure. In addition, it can be connected and fixed to the T-shaped connecting block 6 by screws passing through the top of the upper connecting plate 1 or the bottom of the lower connecting plate 4 into the connecting plate groove 19.

[0017] In this embodiment, the magnetic buffer mechanism includes two magnet fixing plates 5. The two magnet fixing plates 5 are respectively fixed to the bottom end of the upper damping plate 2 and the top end of the lower damping plate 3 by multiple fixing elements 9. The magnet fixing plates 5 are fixedly connected to the mounting magnets 11 by multiple corresponding mounting holes 10 and mounting screws. The fixing elements 9 are bolts, screws and other fixing structures. The magnet fixing plates 5 are used to fix the mounting magnets 11. The mounting magnets 11 are permanent magnets or electromagnets and other magnetic structures. In this embodiment, permanent magnets are used.

[0018] In this embodiment, the damping buffer mechanism includes a first damper fixing plate 12, a first damper connector 13, a damper 14, a second damper connector 15, a second damper fixing plate 16, and a spherical connecting block 17. The bottom end of the upper connecting plate 1 and the top end of the lower connecting plate 4 are each provided with multiple spherical grooves. The first damper connector 13 and the second damper connector 15 are each connected to the spherical connecting block 17 via connecting rods.

[0019] In this embodiment, the magnetic buffer mechanisms provided at the bottom of the upper damping plate 2 and the top of the lower damping plate 3 have the same magnetism, and magnetic buffering is achieved by using the repulsion of like poles.

[0020] Working principle: The upper connecting plate 1 is connected to the upper structure of the bridge by bolts, and the lower connecting plate 4 is connected to the lower structure of the bridge by bolts. In the event of an earthquake or other situation, the bridge will compress the upper connecting plate 1 and the lower connecting plate 4. First, the disc spring 8 will be compressed for the first buffer. At the same time, the mounting magnet 11 between the upper damping plate 2 and the lower damping plate 3 will provide a second magnetic buffer through the same magnetic force. In addition, the damper 14 can provide a third buffer. When a horizontal thrust is generated, the damper 14 can rotate in all directions due to the spherical connecting blocks 17 on the first damper connector 13 and the second damper connector 15, thereby buffering the horizontal thrust. At the same time, it can pull the upper connecting plate 1 and the lower connecting plate 4 back to their initial positions, realizing the automatic return of the structure and ensuring the stability of the bridge.
