Technical Field

[0001] This utility model relates to the technical field of steel bridge expansion joint shielding plates, specifically a novel steel bridge expansion joint shielding plate device. Background Technology

[0002] Expansion joints in steel bridges are crucial devices used in bridge engineering to regulate deformation of bridge structures caused by factors such as temperature changes, load effects, and concrete shrinkage. Steel bridge expansion joints play a vital role in modern bridge engineering, and their proper design and installation are essential for ensuring the normal operation and structural safety of bridges.

[0003] In steel bridges, expansion joint steel shields are mainly used at the expansion joint locations, on the sides of crash barriers, and between two spans of precast beams. Due to long-term deformation of the expansion joints, the shields are prone to damage, including loose anchor bolts and warped edges, posing a safety hazard to vehicles. Furthermore, the shields and concrete guardrails are made of different materials, which can lead to color differences and poor aesthetics, affecting the overall appearance of the shields. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of steel bridge expansion joint cover plate device to solve the problem mentioned in the background art that the bridge structure will deform due to the external environment during use. When deformed, it will pull the cover plate of the expansion joint. The tension will cause the cover plate to break, resulting in the bolts of the cover plate falling off to the road surface and the edges curling up, which will cause safety hazards to driving and affect the aesthetics of the cover plate.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel steel bridge expansion joint shielding device, comprising a base, two support frames on the top of the base, a connecting component for connecting to the steel bridge expansion joint inside the support frames, the connecting component including a slot inside the support frames, a mold frame inside the slot, a casting groove on one side of the mold frame, and multiple damping blocks on the inner wall of the casting groove;

[0006] The inner wall of the hollow groove is provided with multiple docking grooves, and inclined plates are provided on both sides of the inner wall of the multiple docking grooves. Multiple sliding grooves are provided on both sides of the outer wall of the mold frame, and sliders and multiple clamping plates are provided on the inner wall of the multiple sliding grooves.

[0007] Preferably, the two support frame arrays are distributed on both sides of the top of the base, the slots inside the support frames face outwards from the base, and the base is located between the expansion joints of the concrete guardrail.

[0008] Preferably, the mold frame is located in the empty slot of the support frame and is slidably connected to the inner wall of the empty slot. The casting groove in the mold frame is connected to the outside of the base, and the array of multiple damping blocks is distributed on the inner wall of the casting groove.

[0009] Preferably, concrete connectors are poured into the casting groove of the formwork, and the concrete connectors are connected to the steel bridge railing.

[0010] Preferably, the array of multiple docking slots is distributed on the inner wall of the empty slot and corresponds to the sliding angle of the outer wall of the mold frame. The inclined plate is connected to the inner wall of the docking slot, the inclined plate is at an inclined angle, and one end is an arc-shaped structure.

[0011] Preferably, one end of the slider is located in the groove and connected to the inner wall of the groove, while the other end extends into the docking groove and abuts against the inclined plate. The array of multiple card plates is distributed on the inner wall of the groove and abuts against the slider.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By creating a hollow structure before pouring the guardrail, and then pouring concrete into the formwork inside the support frame to form a support component, which extends into the cavity reserved in the guardrail, thus passing through the formwork and the guardrail to connect the formwork and the guardrail. It can cooperate with the formwork at the expansion joint of the guardrail to form a protruding support plate, which is embedded and connected with the support frame. It can replace bolts to connect the support frame for the shielding to the expansion joint of the guardrail, and effectively avoid the defects of traditional steel shielding plates warping and bolt loosening.

[0014] 2. Furthermore, the formwork and the support frame can slide and expand internally, so when deformation occurs in the expansion joint area, it will push the formwork to expand and expand synchronously within the support frame, thereby reducing the impact of expansion joint deformation on the support frame. In addition, concrete can be applied to the outside of the support frame to match the color of the surrounding concrete, reducing color difference and improving the appearance.

[0015] This utility model uses mold casting to connect the support frame and the guardrail expansion joint, which can effectively avoid the problems of warping edges and loose bolts in traditional steel guardrails. Furthermore, applying concrete to the outside of the support frame can reduce color difference and improve the appearance of the guardrail. The structure is simple and easy to replace and carry.

[0021] 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.

[0022] All devices in this application adopt conventional models in the prior art, and the control method is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field, so this application will not explain it in detail.

[0023] Please see the appendix Figure 1-2 As shown, a novel steel bridge expansion joint shielding device includes a base 1. Two support frames 2 are mounted on the top of the base 1. Connecting components for the steel bridge expansion joint are installed inside the support frames 2. Each connecting component includes a slot 201 inside the support frames 2. The slot 201 can accommodate a formwork 3 and position the formwork 3 during sliding expansion and contraction. The formwork 3 is installed inside the slot 201, and a pouring groove 301 is provided on one side of the formwork 3. When connecting the support frames 2 to the expansion joint of the steel bridge railing, a cavity can be reserved inside the railing, and concrete protrusions can be poured into the pouring groove 301, extending into the reserved cavity to connect the formwork 3 to the railing. Multiple damping blocks 302 are provided on the inner wall of the pouring groove 301. The damping blocks 302 increase the friction between the concrete and the pouring groove 301 during concrete pouring, ensuring the stability of the pouring process.

[0024] Two support frames 2 are arrayed on both sides of the top of the base 1. The empty grooves 201 inside the support frames 2 face the outside of the base 1. The base 1 is located between the expansion joints of the concrete guardrail. The formwork 3 is located in the empty grooves 201 of the support frames 2 and is slidably connected to the inner wall of the empty grooves 201. The pouring groove 301 inside the formwork 3 is connected to the outside of the base 1. Multiple damping blocks 302 are arrayed on the inner wall of the pouring groove 301. Concrete connectors are poured in the pouring groove 301 of the formwork 3, and the concrete connectors are connected to the steel bridge guardrail.

[0025] In this embodiment: before installing the support frame 2 of the expansion joint, a cavity structure is reserved at one end near the expansion joint when pouring the steel bridge railing. Then, concrete is poured into the pouring groove 301 of the formwork 3 to form a protrusion. During pouring, the other end of the concrete protrusion extends into the cavity reserved in the railing, so that the formwork 3 is connected to the railing. The railing is connected to the support frame 2 by concrete inlay. The support frame 2 can be connected by bolt fixing instead of bolt fixing.

[0026] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figures 2-4 The inner wall of the slot 201 is provided with multiple docking slots 4. The docking slots 4 correspond at an angle to the sliding grooves 5 on the outer wall of the mold frame 3. Both sides of the inner wall of the multiple docking slots 4 are provided with inclined plates 401. The inclined plates 401 can support the sliders 6 extending into the docking slots 4 through their own toughness. Both sides of the outer wall of the mold frame 3 are provided with multiple sliding grooves 5. The inner wall of the multiple sliding grooves 5 is provided with sliders 6 and multiple locking plates 501. The locking plates 501 can support the sliders 6 in the sliding grooves 5 and drive the mold frame 3 to slide in the slot 201 of the support frame 2 when the mold frame 3 is deformed by the guardrail. The support frame 2 has two sections on each side, which are locked by bolts, so that it can be disassembled after use and is convenient for multiple uses.

[0027] Multiple docking slots 4 are arrayed on the inner wall of the empty slot 201 and correspond at an angle to the slide groove 5 on the outer wall of the mold frame 3. The inclined plate 401 is connected to the inner wall of the docking slot 4. The inclined plate 401 is at an inclined angle and one end is an arc structure. One end of the slider 6 is located in the slide groove 5 and is connected to the inner wall of the slide groove 5. The other end extends into the docking slot 4 and abuts against the inclined plate 401. Multiple clamping plates 501 are arrayed on the inner wall of the slide groove 5 and abut against the slider 6.

[0028] In this embodiment: During the use of the support frame 2, when the guardrail deforms, it will cause the formwork 3 to slide and extend synchronously within the support frame 2. During sliding, the slider 6 slides within the connecting groove 4 and the sliding channel 5, and is supported by the inclined plate 401. At the same time, when the slider 6 slides within the sliding channel 5, it will squeeze the clamping plate 501 and cause the clamping plate 501 to break. In the normal state, the clamping plate 501 and the inclined plate 401 provide abutment support between the formwork 3 and the support frame 2. After the support frame 2 is connected to the guardrail, concrete is applied to the outside of the support frame 2 to reduce the color difference with the guardrail, improve the aesthetics, and the durability of the support frame 2 is better than that of traditional expansion joint cover plates, making it easy to replace and carry.
