Description

Technical Field

[0001] This utility model belongs to the field of bridge construction engineering, specifically relating to prefabricated bridge support devices. Background Technology

[0002] Bridge support systems are devices installed between the substructure (such as piers and abutments) and the superstructure (such as beams and deck) of a bridge, or used to connect and secure various parts of the bridge. Their main function is to support the weight of the superstructure and transfer the load to the substructure, while ensuring the stability and safety of the bridge under various load and environmental conditions.

[0003] In existing bridge structures, adjacent piers often operate independently. When subjected to external forces (such as vehicle loads, wind force, seismic force, etc.), it is difficult for them to coordinate the force distribution. This can lead to the failure of individual piers due to excessive stress. During bridge operation, the curing of pier concrete is an important issue, especially in high-temperature or dry environments where moisture evaporates too quickly, which can easily lead to problems such as plastic cracks, reduced strength, and decreased durability in the concrete.

[0004] Therefore, existing bridge support devices suffer from problems such as insufficient coordinated force, excessive relative displacement, and difficulty in water replenishment and maintenance during use. Utility Model Content

[0005] To overcome the problems of insufficient coordinated force, excessive relative displacement, and difficulty in water replenishment and maintenance of existing bridge support devices during use, a prefabricated bridge support device was proposed.

[0006] The technical solution of this utility model is as follows: a prefabricated bridge support device, including a first connecting frame; it also includes a second connecting frame and a triangular support frame. The second connecting frame is slidably arranged at the front end of the first connecting frame. Triangular support frames are arranged at the lower ends of both the first and second connecting frames. A lower pier, a lower pad, and an upper pad are arranged at the ends of the first and second connecting frames that are far apart from each other. The triangular support frame has a triangular structure, and the right-angled side is in contact with one outer wall of the lower pier. A water storage tank is arranged at the upper end of the triangular support frame. A first connecting pipe is arranged through the left and right ends of the water storage tank. The two first connecting pipes are connected to a second connecting pipe. The lower end of the second connecting pipe is provided with evenly distributed drippers. The inner wall of the second connecting pipe is in contact with the outer wall of the lower pier. The second connecting pipe is inclined on the lower pier. The angle of the end of the second connecting pipe that is far away from the two lower piers and close to each other is offset downward.

[0007] Preferably, the upper end of the lower pier is fixed with uniformly distributed reinforcing bars, the upper pier is placed on the upper end of the reinforcing bars, and the lower end of the upper pier is provided with a first slot that corresponds one-to-one with the reinforcing bars and is uniformly distributed. The inner wall of the first slot and the outer wall of the reinforcing bars fit together.

[0008] Preferably, the lower pad and the upper pad are placed at the ends of the lower pier and the upper pier that are close to each other. The lower end of the lower pad is attached to the upper end of the lower pier, and the lower and upper ends of the lower pad are provided with evenly distributed second slots. The upper end of the upper pad is attached to the lower end of the upper pier, and the upper and lower ends of the upper pad are provided with evenly distributed third slots.

[0009] Preferably, the inner wall of the second slot and the outer wall of the reinforcing bar are fitted together, and the inner wall of the third slot and the outer wall of the reinforcing bar are fitted together.

[0010] Preferably, a second slot is fixed to the upper end of the plane at the four corners of the inner wall of the lower pad, and a rubber shock-absorbing pad is placed inside the first limiting mounting ring.

[0011] Preferably, a second limiting mounting ring is fixed at the four corners of the inner wall of the upper pad, and the arc-shaped outer wall of the rubber shock-absorbing pad and the arc-shaped outer wall of the second limiting mounting ring fit together.

[0012] Preferably, the front end of the first connecting frame is fixed with two sliding columns, and the rear end of the second connecting frame is provided with two sliding grooves, with the outer wall of the sliding column and the inner wall of the sliding groove fitting together.

[0013] The beneficial effects of this utility model are as follows: By placing two lower pads on the upper ends of two lower piers respectively, and then sliding and fixing the first connecting frame and the second connecting frame into the upper ends of the corresponding lower piers, the triangular support frame at the lower ends of the first connecting frame and the second connecting frame can effectively improve the coordinated force between the two piers and reduce relative displacement, thereby improving stress distribution and increasing the overall load-bearing capacity of the piers.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-6 This utility model provides an embodiment of a prefabricated bridge support device, including a first connecting frame 1; it also includes a second connecting frame 2 and a triangular support frame 3. The second connecting frame 2 is slidably disposed at the front end of the first connecting frame 1. Triangular support frames 3 are disposed at the lower ends of both the first connecting frame 1 and the second connecting frame 2. A lower pier 4, a lower pad 5, and an upper pad 6 are disposed at the ends of the first connecting frame 1 and the second connecting frame 2 that are far apart from each other. The triangular support frame 3 has a triangular structure, and its right-angled side is in contact with one side of the outer wall of the lower pier 4. A water storage tank 301 is disposed at the upper end of the triangular support frame 3. A first connecting pipe 302 is disposed through the left and right ends of the water storage tank 301. The two first connecting pipes 302 are connected to a second connecting pipe 303. The lower end of the second connecting pipe 303 is provided with evenly distributed drippers 304. The inner wall of the second connecting pipe 303 and the lower pier 4 are connected to the lower pier 4. The outer walls of the piers 4 are closely fitted together. The second connecting pipe 303 is inclined on the lower pier 4. The end of the second connecting pipe 303 away from the two lower piers 4 is offset downwards. By placing the two lower pads 5 on the upper ends of the two lower piers 4 respectively, and then sliding and inserting the first connecting frame 1 and the second connecting frame 2 into the upper ends of the corresponding lower piers 4 respectively, the triangular support frame 3 at the lower end of the first connecting frame 1 and the second connecting frame 2 can effectively improve the coordinated force between the two piers and reduce the relative displacement, thereby improving the stress distribution and improving the overall bearing capacity of the piers. In daily use, water is injected into the water storage tank 301, and the water flows into the second connecting pipe 303 through the first connecting pipe 302. Then, the water flows through the dripper 304 to spray water on the outer walls of the two lower piers 4 for protection, which can maintain the piers and ensure the concrete strength, etc.

[0023] Please see Figures 1-2In this embodiment, two sliding columns 101 are fixedly connected to the front end of the first connecting frame 1, and two sliding grooves 201 are opened at the rear end of the second connecting frame 2. The outer wall of the sliding column 101 and the inner wall of the sliding groove 201 fit together. The first connecting frame 1 and the second connecting frame 2 are slidable, which makes it convenient to fine-tune the distance between them later.

[0024] Please see Figures 3-6 In this embodiment, the upper end of the lower pier 4 is fixed with uniformly distributed reinforcing bars 401. The upper pier 402 is placed on the upper end of the reinforcing bars 401. The lower end of the upper pier 402 has a first slot 403 that corresponds one-to-one with the reinforcing bars 401 and is uniformly distributed. The inner wall of the first slot 403 and the outer wall of the reinforcing bars 401 are in contact with each other. After the upper pier 402 inserts the reinforcing bars 401 through the first slot 403, it is limited and fixed, thereby enabling subsequent installation work. The lower pad 5 and the upper pad 6 are placed at the ends of the lower pier 4 and the upper pier 402 that are close to each other. The lower end of the lower pad 5 is in contact with the upper end of the lower pier 4. The upper and lower ends of the lower pad 5 have uniformly distributed second slots 501. The upper end of the upper pad 6 is in contact with the lower end of the upper pier 402. The upper pad 6 has evenly distributed third slots 601. The inner wall of the second slot 501 and the outer wall of the reinforcing bar 401 are in contact with each other. The upper end of the plane at the four corners of the inner wall of the lower pad 5 is fixed with the second slot 501. A rubber shock-absorbing pad 503 is placed inside the first limiting mounting ring 502. The upper pad 6 has a second limiting mounting ring 602 fixed at the four corners of the inner wall. The arc-shaped outer wall of the rubber shock-absorbing pad 503 and the arc-shaped outer wall of the second limiting mounting ring 602 are in contact with each other. In actual use, the lower end of the upper pad 6 does not contact the upper end of the first connecting frame 1 or the second connecting frame 2. The complete support system is achieved through the rubber shock-absorbing pads 503 in the multiple second limiting mounting rings 602 on the upper pad 6.

[0025] During installation, the second slot 501 is aligned with the reinforcing bar 401 and placed. Two second connecting pipes 303 are then fitted onto the outer walls of the two lower piers 4. Next, the first connecting frame 1 and the second connecting frame 2 are aligned with the reinforcing bar 401 and fitted onto the two connected lower piers 4. Then, the third slot 601 is placed along the reinforcing bar 401. After placement, the rubber shock-absorbing pad 503 on the first limiting installation ring 502 is inserted into the second limiting installation ring 602 for positioning. Finally, the first slot 403 on the upper pier 402 is placed along the reinforcing bar 401, completing the overall installation. During use, connecting the two lower piers 4 with the triangular support frame 3 results in a more uniform stress distribution in the bridge structure. The stress that might have been concentrated on a single lower pier 4 is distributed to adjacent lower piers 4 through the support frame, reducing the stress level of a single lower pier 4. At the same time, the triangular support frame 3 can coordinate the vibration of adjacent piers, preventing damage to a single pier due to excessive stress, thereby improving the overall integrity and stability of the entire bridge structure. During routine maintenance, water is injected downwards from the bridge deck into the water storage tank 301 or automatically collected in the water storage tank 301 during rainy days. The liquid then flows into the first connecting pipe 302 and the second connecting pipe 303 and flows out through the dripper 304, thus replenishing the surface of the lower pier 4. This effectively prevents water from evaporating too quickly and ensures the normal hardening of the concrete.
