[0040] As described in the background, in bridge engineering, the bridge deck material will deform due to thermal expansion and contraction, concrete creep and other factors, so it is necessary to reserve bridge expansion joints on the bridge deck. However, the existing bridge expansion joints have poor waterproof effect during use, rainwater seeps from the expansion joints, causing concrete corrosion, which will seriously affect the structural safety and service life of the bridge in the long run, and will also increase the maintenance frequency and repair cost of the bridge.
[0041] Based on this, please refer to Figures 1-4 The embodiment of the utility model provides a bridge expansion joint structure 100, which can effectively improve the above-mentioned technical problems, that is, it can improve the waterproof effect of the expansion joint 001, prolong the service life of the bridge, ensure the safety of the bridge structure, and reduce the maintenance frequency and repair cost of the bridge. The bridge expansion joint structure 100 will be described in detail below.
[0042] Please refer to Figures 1-3 , Figure 1 The first perspective view of the bridge expansion joint structure 100 provided for the embodiment is shown in the structure schematic view, Figure 2A structural schematic diagram of a second perspective of the bridge expansion joint structure 100 provided in the embodiment, Figure 3 An exploded view of the bridge expansion joint structure 100 provided in the embodiment.
[0043] In combination Figures 1-3 The bridge expansion joint structure 100 includes a first bridge road 10, a second bridge road 20, a first waterproof structure 30, a fixed plate 40, and a second waterproof structure 50. The first bridge road 10 is provided with a first mounting groove 11. The second bridge road 20 has an expansion joint 001 with the first bridge road 10, and is provided with a second mounting groove 21. The first mounting groove 11 and the second mounting groove 21 are both in communication with the expansion joint 001. The first waterproof structure 30 is arranged in the first mounting groove 11 and the second mounting groove 21, and is used to close the expansion joint 001. The fixed plate 40 is arranged on the first waterproof structure 30 and located in the first mounting groove 11 and the second mounting groove 21.

The second waterproof structure 50 is arranged on the side of the fixed plate 40 away from the first waterproof structure 30 and located in the first mounting groove 11 and the second mounting groove 21.
[0044] It is easy to understand that the first waterproof structure 30 and the second waterproof structure 50 can play a waterproof role, and the fixed plate 40 can play a role of connecting the first bridge road 10 and the second bridge road 20, ensuring the stability between the two bridge roads. By arranging the fixed plate 40 between the first waterproof structure 30 and the second waterproof structure 50, the three cooperate together to protect the fixed plate 40 while achieving multiple waterproof effects. Rainwater is not easy to penetrate into the expansion joint 001, protecting the bridge structure from damage, reducing the erosion of water to the bridge structure, thereby prolonging the service life of the bridge, ensuring the safety of the bridge structure, and reducing the maintenance frequency and repair cost of the bridge.
[0045] It should be noted that in the embodiment, the fixed plate 40 is a steel plate. Of course, in other embodiments, the fixed plate 40 can also be of other materials.

[0047] The rubber belt 32 can prevent external substances from entering and prevent debris from blocking, reduce the transmission of noise and vibration; at the same time, it has a certain elasticity, which can adapt to the deformation of the bridge structure and absorb and resist the small displacement of the bridge. The first waterproof aluminum plate 31 not only has a certain structural strength, but also can effectively prevent water from penetrating into the expansion joint 001, thereby improving the service life and structural safety of the bridge.
[0048] It should be noted that the material of the rubber belt 32 can be neoprene, butyl rubber, ethylene-propylene-diene rubber or chlorinated polyethylene, etc., which is not limited in the embodiment. The specific material needs to be selected according to the application scenario.
[0049] Further, in the embodiment, the rubber belt 32 is provided with an arc-shaped groove 321, and the arc-shaped groove 321 is located in the expansion joint 001. By providing the arc-shaped groove 321, the structural deformation of the bridge during use can be adapted, and the waterproof effect is further improved.

[0055] During construction, the first reinforcing steel 62 and the second reinforcing steel 72 are welded with the fixed plate 40 at the same time, and then extend into the first bridge road 10 and the second bridge road 20 respectively. Then, cement is poured at the positions of the first reinforcing steel 62 and the second reinforcing steel 72. After the cement solidifies, the cement layer formed can form an integral structure with the first bridge road 10 and the second bridge road 20 respectively, thereby improving the structural stability of the bridge as a whole.
[0056] Please continue to combine Figure 3 In order to facilitate the installation of the waterproof structure and the reinforcing structure, in the embodiment, a third installation groove 12 is formed in the bottom wall of the first installation groove 11, and a fourth installation groove 22 is formed in the bottom wall of the second installation groove 21.

Through this arrangement, installation and construction can be facilitated, and the installation stability of the waterproof structure and the reinforcing structure can be improved, while ensuring the flatness of the installed bridge road.
[0057] Please continue to combine Figures 1-3 The bridge expansion joint structure 100 further comprises a buffer structure 80. The buffer structure 80 comprises a first spring steel 81, a second spring steel 82 and a buffer block 83. The first spring steel 81 and the second spring steel 82 are arranged in the expansion joint 001 at intervals, and the first spring steel 81 abuts against the side wall of the first bridge road 10 and the second spring steel 82 abuts against the side wall of the second bridge road 20. The buffer block 83 is arranged between the first spring steel 81 and the second spring steel 82 and abuts against the first spring steel 81 and the second spring steel 82 at the same time.
[0058] Through the cooperation of the first spring steel 81, the buffer block 83 and the second spring steel 82, a better buffering effect can be achieved, the stress of the bridge structure is reduced, and the service life of the bridge is prolonged. In this way, the expansion joint 001 can prevent the bridge structure from being damaged due to excessive deformation by absorbing and dispersing the deformation of the bridge under various external factors.
