Description

Technical Field

[0001] This utility model relates to the field of bridge expansion joint technology, specifically a bridge expansion joint protection device. Background Technology

[0002] Bridges expand and contract with temperature changes, which can severely affect the bridge structure. To mitigate this effect, expansion joints are typically installed on bridges. These joints expand and contract with the bridge structure as it expands and contracts with temperature changes, thereby reducing the stress on the bridge.

[0003] According to a utility model patent with Chinese patent application number 202322719102.6, a highway bridge expansion joint can solve the problem that existing expansion joint connection devices rely solely on the connection structure, resulting in reduced stability and low connection strength. However, this highway bridge expansion joint lacks a water-guiding structure, and excessive rainwater, if not drained in time, can seep into the bridge. Rainwater is acidic and can easily corrode the internal structure of the bridge, potentially causing bridge collapse. Therefore, it is necessary to propose a bridge expansion joint protection device to solve the aforementioned problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a bridge expansion joint protection device that enables bridge expansion joints to have water-guiding functions, thus solving the problem that expansion joints in the prior art do not have water-guiding functions.

[0005] To achieve the above-mentioned purpose of enabling bridge expansion joints to have water-guiding function, this utility model provides the following technical solution: a bridge expansion joint protection device, including a first bridge deck, a second bridge deck is provided on the right side of the first bridge deck, a fixing plate is installed on the top of the first bridge deck and the second bridge deck, inclined plates are provided on both the left and right sides of the fixing plate, a limit plate is provided on the top of the first bridge deck and the second bridge deck, and a water-guiding structure is provided on the outside of the first bridge deck and the second bridge deck.

[0006] The water guiding structure includes a first water guiding channel, the top of the fixed plate is provided with a first water guiding channel, the top of the limiting plate is provided with a second water guiding channel, a first water guiding plate is provided on one side of the first bridge deck and the second bridge deck respectively, a third water guiding channel and a fourth water guiding channel are provided on the top of the first water guiding plate, and a second water guiding plate is fixedly installed on the rear side of the first bridge deck and the second bridge deck.

[0007] Furthermore, the second water guide channel is connected to the third water guide channel and the fourth water guide channel, and a second water guide plate is provided at the end of the fourth water guide channel.

[0008] Furthermore, a base is provided at the bottom of the first bridge deck and the second bridge deck, a balance plate is provided at the top of the base, and a balance plate is provided between the first bridge deck and the second bridge deck.

[0009] Furthermore, the side of the balance plate is provided with an insertion hole, through which the first water guide plate is inserted and penetrates the interior of the balance plate.

[0010] Furthermore, hydraulic dampers are provided on one side of each of the first and second bridge decks, respectively, and the hydraulic dampers are located between the first and second bridge decks and the balance plate.

[0011] Furthermore, the top of the balance plate is provided with a countersunk hole, and the top of the fixing plate is equipped with fastening bolts. The fixing plate is fixedly installed to the balance plate by the fastening bolts.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] This bridge expansion joint protection device, through the setting of a water guiding structure, allows rainwater on the top of the fixed plate to be guided through the first water guiding channel to the interior of the second water guiding plate during use. The inclined plate, the first bridge deck, and the second bridge deck can further guide the rainwater, which flows from the gap between the inclined plate and the limiting plate into the interior of the second, third, and fourth water guiding channels. Finally, the water is guided to the water-bearing area, and the rainwater on the bridge deck is guided to the second water guiding plate for discharge. Furthermore, the interior of the second, third, and fourth water guiding channels and the second water guiding plate are all set with an inclined surface, which can guide the rainwater out more quickly and prevent rainwater from lingering in the expansion joint and affecting its service life.

[0014] This bridge expansion joint protection device incorporates hydraulic dampers located on both sides of a balance plate, connecting the first and second bridge decks. These dampers disperse impact forces, reducing the damage to the expansion joints from dynamic loads and minimizing noise and vibration transmission to the main beam. A limiting plate allows the expansion joint to slide along the bottom of an inclined plate via an internal expansion groove when the first and second bridge decks move closer or further apart during expansion. This ensures the inclined plate and fixed plate remain at the top of the expansion joint, preventing displacement from affecting their protective effect. Fastening bolts secure the inclined plate and fixed plate to the top of the balance plate, facilitating disassembly, replacement, and maintenance. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 A bridge expansion joint protection device in this embodiment includes a first bridge deck 1, a second bridge deck 2 provided on the right side of the first bridge deck 1, a fixing plate 4 installed on the top of the first bridge deck 1 and the second bridge deck 2, inclined plates 3 provided on both the left and right sides of the fixing plate 4, a limit plate 5 provided on the top of the first bridge deck 1 and the second bridge deck 2, and a water guiding structure 11 provided on the outside of the first bridge deck 1 and the second bridge deck 2.

[0021] The water guiding structure 11 includes a first water guiding channel 111, the top of the fixing plate 4 is provided with the first water guiding channel 111, the top of the limiting plate 5 is provided with the second water guiding channel 113, the first bridge deck 1 and the second bridge deck 2 are respectively provided with a first water guiding plate 112, the top of the first water guiding plate 112 is provided with a third water guiding channel 115 and a fourth water guiding channel 116, and the second water guiding plate 114 is fixedly installed on the rear side of the first bridge deck 1 and the second bridge deck 2.

[0022] In the implementation of the case, by setting up the water guiding structure 11, during use, rainwater on the top of the fixed plate 4 is guided to the interior of the second water guiding plate 114 through the first water guiding channel 111. The inclined plate 3, the first bridge deck 1 and the second bridge deck 2 can further guide the rainwater, which flows from the gap between the inclined plate 3 and the limiting plate 5 into the interior of the second water guiding channel 113, the third water guiding channel 115 and the fourth water guiding channel 116. Finally, the water is guided to the water-bearing area, and the rainwater on the bridge deck is guided to the second water guiding plate 114 for discharge. The interior of the second water guiding channel 113, the third water guiding channel 115, the fourth water guiding channel 116 and the second water guiding plate 114 are all set as inclined surfaces, which can guide the rainwater out more quickly and avoid the rainwater from staying in the expansion joint and affecting the service life of the expansion joint.

[0023] In the implementation of the case, by setting up hydraulic dampers 8, which are located on the left and right sides of the balance plate 6 and connected between the first bridge deck 1 and the second bridge deck 2, the impact force can be dispersed, the damage of dynamic load to the expansion joint can be reduced, and the transmission of noise and vibration to the main beam can be reduced.

[0024] In the implementation of the case, by setting the limiting plate 5, when the first bridge deck 1 and the second bridge deck 2 move closer or further apart during expansion and contraction, the expansion groove 13 set inside the limiting plate 5 will slide to the bottom of the inclined plate 3, so that the inclined plate 3 and the fixed plate 4 are always at the top of the expansion joint, avoiding displacement that affects the protective effect of the inclined plate and the fixed plate 4 on the expansion joint.

[0025] In the case implementation, by setting fastening bolts 9, the inclined plate 3 and the fixed plate 4 are fixed to the top of the balance plate 6, which makes it convenient to disassemble, replace and repair the inclined plate 3 and the fixed plate 4.

[0026] When implementing this procedure, please follow these steps:

[0027] 1) First, the inclined plate 3 and the fixed plate 4 are fixed to the top of the balance plate 6 with fastening bolts 9, so that the inclined plate 3 and the fixed plate 4 can be disassembled, replaced and repaired.

[0028] 2) Then the rainwater at the top of the fixed plate 4 is guided through the first water guide channel 111 to the inside of the second water guide plate 114;

[0029] 3) The rainwater can be further guided through the inclined plate 3, the first bridge deck 1 and the second bridge deck 2, and flows into the interior of the second water guide channel 113, the third water guide channel 115 and the fourth water guide channel 116 from the gap between the inclined plate 3 and the limiting plate 5.

[0030] 4) Finally, the water is guided to the water-bearing area, and the rainwater on the bridge surface is guided to the second water guide plate 114 for discharge.

[0031] In summary, this bridge expansion joint protection device, by setting up a water guiding structure 11, allows rainwater from the top of the fixed plate 4 to be guided through the first water guiding channel 111 to the interior of the second water guiding plate 114 during use. Furthermore, the inclined plate 3, the first bridge deck 1, and the second bridge deck 2 can further guide the rainwater, which flows from the gap between the inclined plate 3 and the limiting plate 5 into the interior of the second water guiding channel 113, the third water guiding channel 115, and the fourth water guiding channel 116, ultimately completing the water guiding to the water-bearing area and guiding the rainwater on the bridge deck to the second water guiding plate 114 for discharge. Moreover, the interiors of the second water guiding channel 113, the third water guiding channel 115, the fourth water guiding channel 116, and the second water guiding plate 114 are all set in an inclined shape, which can guide the rainwater out more quickly and prevent rainwater from lingering in the expansion joint and affecting its service life.

[0032] Furthermore, by setting hydraulic dampers 8, which are located on the left and right sides of the balance plate 6 and connected between the first bridge deck 1 and the second bridge deck 2, the impact force can be dispersed, reducing the damage of dynamic loads to the expansion joint and reducing the transmission of noise and vibration to the main beam. By setting limiting plates 5, when the first bridge deck 1 and the second bridge deck 2 move closer or further apart during expansion and contraction, the expansion grooves 13 set inside the limiting plates 5 will slide to the bottom of the inclined plates 3, so that the inclined plates 3 and the fixed plates 4 are always at the top of the expansion joint, avoiding displacement that affects the protective effect of the inclined plates and the fixed plates 4 on the expansion joint. By setting fastening bolts 9, the inclined plates 3 and the fixed plates 4 are fixed to the top of the balance plate 6, thereby facilitating the disassembly, replacement and maintenance of the inclined plates 3 and the fixed plates 4.
