Abstract
Description
Technical Field
[0001] This utility model belongs to the field of bridge bearing design technology, specifically an improved bridge rubber bearing. Background Technology
[0002] Bridge bearings are important structural components that connect the superstructure and substructure of a bridge. They reliably transfer the reaction force and deformation of the superstructure to the substructure, so that the actual stress condition of the structure matches the calculated theoretical diagram. Common bridge bearings are mainly rubber bearings for bridges.
[0003] Most existing bridge rubber bearings are made of rubber and steel plates tightly bonded together. The rubber pad in the middle is sandwiched between two steel plates that connect the pier and the bridge body respectively, and the rubber pad between the two plates buffers the loads on the bridge body in all directions. However, if the bridge body tilts significantly in a short period of time, the entire bearing lacks additional rebound force except for the rubber pad itself, which easily leads to stress concentration and rapid damage to the rubber pad.
[0004] Therefore, this utility model provides an improved bridge rubber bearing. Utility Model Content

[0007] Preferably, a rubber water-proof curtain is provided on the side wall of the rigid top plate, and bolts connect the rigid top plate and the rubber water-proof curtain; a rubber water-proof block is provided on the side wall of the rigid bottom plate, and bolts connect the rigid bottom plate and the rubber water-proof block, and the top of the rubber water-proof block is shaped to correspond to the bottom of the rubber water-proof curtain; this step isolates external water sources by providing rubber water-proof curtains and rubber water-proof blocks on the side walls of the rigid top plate and the rigid bottom plate respectively, preventing rainwater or accumulated water from entering between the rigid top plate and the rigid bottom plate and soaking the various components, keeping the components dry, which helps to extend the service life of the rubber support and thus reduce maintenance costs.
[0008] Preferably, a fixing rod is fixedly connected to the top of the rigid top plate, and multiple fixing rods are symmetrically arranged. The ends of the fixing rods are connected to a mold inside the bridge body. A fixing rod is fixedly connected to the bottom of the rigid bottom plate, and multiple fixing rods are symmetrically arranged. The ends of the multiple fixing rods are connected to a mold inside the pier. Fixing blocks are fixedly connected to the ends of the multiple fixing rods away from the rubber pad body. This step, by setting fixing rods and fixing blocks at the top of the rigid top plate and the bottom of the rigid bottom plate, connects the rigid top plate and the rigid bottom plate to the pier and the bridge body respectively, completely preventing the rigid top plate and the rigid bottom plate from slipping relative to the pier or the bridge body, thereby enhancing the buffering effect of the rubber pad body and making the bridge body more stable.
[0009] Preferably, a placement box is provided on the top of the rigid base plate; a fixing protrusion is fixedly connected to the side wall of the placement box, and a screw is connected between the fixing protrusion and the rigid base plate; this step ensures long-term dryness inside the rubber support by placing a desiccant in the placement box, thereby slowing down the aging rate of the rubber pad body and the high-strength spring, and extending the service life of the rubber support.
[0010] Preferably, an adhesive sheet is fixedly attached to the top and bottom of the rubber pad body; the surface of the adhesive sheet is provided with hemispherical holes, and a plurality of hemispherical holes are arranged in a linear array; this step increases the friction between the rubber pad body and the rigid top plate and rigid bottom plate by fixing the adhesive sheet to the top and bottom of the rubber pad body and providing hemispherical holes on the surface of the adhesive sheet, which helps to prevent the rubber pad body from sliding out between the rigid top plate and rigid bottom plate, thereby enhancing the stability of the rubber support.
[0011] Preferably, the surface of the adhesive sheet is provided with venting grooves, which are opened corresponding to the hemispherical holes, and multiple venting grooves are arranged in a linear array. This step, by setting venting grooves, discharges the high-pressure gas on the surface of the adhesive sheet, avoiding damage to the adhesive sheet and the rubber pad body by a small amount of high pressure, which helps to protect the structural stability of the adhesive sheet and the rubber pad body and reduces safety hazards.
[0012] Preferably, a limiting ring is fixed to the top of the rigid base plate, and the limiting ring is set according to the size of the rubber pad body and the adhesive sheet. This step restricts the position of the rubber pad body by setting the limiting ring and assists the staff in positioning the limiting ring, which helps to prevent the rubber pad body from sliding out under force and enhances the stability of the rubber support.

Detailed Implementation
[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0024] Specific implementation examples are given below.
[0025] like Figures 1 to 5 As shown, an improved bridge rubber bearing according to an embodiment of the present invention includes a rigid top plate 1 and a rigid bottom plate 2; the top of the rigid top plate 1 is provided with a fixing groove 4, and multiple fixing grooves 4 are symmetrically arranged; the bottom of the rigid bottom plate 2 is provided with a fixing groove 4, and multiple fixing grooves 4 are symmetrically arranged; a limiting shaft 5 is provided inside the multiple fixing grooves 4, and the limiting shaft 5 is set to correspond to the size of the fixing groove 4; a fixing ring 16 is slidably connected to the middle of the limiting shaft 5, and a high-strength spring 6 is fixed between the corresponding fixing rings 16; the rigid top plate 1 and the rigid bottom plate 2 are connected together. A rubber pad body 3 is provided. During operation, the rigid top plate 1 is in close contact with the bridge body, and the rigid bottom plate 2 is in close contact with the piers. Whenever the rigid top plate 1 bears a load from the bridge body, the load from the bridge body is transmitted sequentially through the rigid top plate 1, the rubber pad body 3, and the rigid bottom plate 2 to the piers, and finally the piers transmit all the loads and their own weight to the ground. During the force transmission process, if the bridge body is subjected to tangential stress, this stress is also transmitted among the rigid top plate 1, the rubber pad body 3, and the rigid bottom plate 2. Whenever these three parts bear a load from the bridge body... Under tangential force or instantaneous longitudinal force, the rubber pad body 3 located between the rigid top plate 1 and the rigid bottom plate 2 absorbs such stress through its own deformation. Multiple high-strength springs 6 located between the rigid top plate 1 and the rigid bottom plate 2 apply tension to the rigid top plate 1 and the rigid bottom plate 2 through their own fixing rings 16, limiting shafts 5, and fixing grooves 4. Whenever the rubber pad body 3 deforms and tilts, the rigid top plate 1 and the rigid bottom plate 2 tilt simultaneously, and the multiple high-strength springs 6 located between the rigid top plate 1 and the rigid bottom plate 2 are stretched. This results in a greater tensile force being applied to the rigid top plate 1 and the rigid bottom plate 2, thereby restoring the tilt after the stress disappears. This step involves setting multiple high-strength springs 6 between the rigid top plate 1 and the rigid bottom plate 2 to assist the rubber pad body 3 between the rigid top plate 1 and the rigid bottom plate 2 in coping with the bridge stress. This achieves elastic fixation of the rigid top plate 1, the rigid bottom plate 2, and the rubber pad body 3, improving the load-bearing capacity of the rubber bearing, enhancing the strength of the rubber bearing, and increasing the risk resistance of the rubber bearing. This is beneficial for raising the damage threshold of the rubber pad body 3.
[0026] like Figure 1 and Figure 2As shown, a rubber water-proof curtain 7 is installed on the side wall of the rigid top plate 1, and bolts 17 connect the rigid top plate 1 and the rubber water-proof curtain 7; a rubber water-proof block 8 is installed on the side wall of the rigid bottom plate 2, and bolts 17 connect the rigid bottom plate 2 and the rubber water-proof block 8, with the top of the rubber water-proof block 8 corresponding to the bottom shape of the rubber water-proof curtain 7; during operation, the bottom of the rubber water-proof curtain 7 is in close contact with the top of the rubber water-proof block 8 due to gravity and its own shape. Except for human factors, the rubber water-proof curtain 7 and the rubber water-proof block 8 can maintain a close contact for a long time, thereby isolating rainwater, accumulated water and other external water sources, keeping the internal space between the rigid top plate 1 and the rigid bottom plate 2 dry, and thus... To mitigate the impact of moisture on components such as the high-strength spring 6 and the rubber pad body 3, and to maintain the normal operation of each component, whenever it is necessary to replace the rubber pad body 3 between the rigid top plate 1 and the rigid bottom plate 2, the operator can first remove multiple bolts 17 to separate the rubber water curtain 7 and the rubber water-proof block 8, and then carry out the replacement of the rubber pad body 3. This step, by setting the rubber water curtain 7 and the rubber water-proof block 8 on the side walls of the rigid top plate 1 and the rigid bottom plate 2 respectively to isolate external water sources, prevents rainwater or accumulated water from entering between the rigid top plate 1 and the rigid bottom plate 2 and soaking the components, keeps the components dry, helps to extend the service life of the rubber support, and thus reduces maintenance costs.
[0027] like Figure 1 As shown, a fixing rod 9 is fixedly connected to the top of the rigid top plate 1, and multiple fixing rods 9 are symmetrically arranged. The ends of the fixing rods 9 are connected to the mold inside the bridge body. A fixing rod 9 is fixedly connected to the bottom of the rigid bottom plate 2, and multiple fixing rods 9 are symmetrically arranged. The ends of the multiple fixing rods 9 are connected to the mold inside the pier. The ends of the multiple fixing rods 9 away from the rubber pad body 3 are fixedly connected to fixing blocks 10. During operation, the rigid bottom plate 2 is connected to the pier through the multiple fixing rods 9 at its bottom, and the rigid top plate 1 is connected to the bridge body through the multiple fixing rods 9 at its top. During construction, the construction personnel should place the rubber bearing on the horizontal platform at the top of the pier during the pier construction stage, and fix the multiple fixing rods 9 at the bottom of the rigid bottom plate 2 and the ends of the multiple fixing rods 9. The fixing block 10 of the part is connected to the steel reinforcement group inside the platform, or the fixing rod 9 at the bottom of the rigid base plate 2 is installed in the mold inside the platform. During the bridge construction stage, the construction personnel should also connect the rigid top plate 1 to the steel reinforcement structure of the bridge body through multiple fixing rods 9 and fixing blocks 10 at the top of the rigid top plate 1, or install the fixing rod 9 at the top of the rigid top plate 1 into the mold inside the bridge body. This step, by setting fixing rods 9 and fixing blocks 10 at the top of the rigid top plate 1 and the bottom of the rigid base plate 2, connects the rigid top plate 1 and the rigid base plate 2 to the pier and the bridge body respectively, completely preventing the rigid top plate 1 and the rigid base plate 2 from slipping relative to the pier or the bridge body, thereby enhancing the buffering effect of the rubber pad body 3 and making the bridge body more stable.
[0028] like Figure 3 and Figure 5 As shown, a placement box 11 is provided on the top of the rigid base plate 2; a fixing protrusion 15 is fixedly connected to the side wall of the placement box 11, and a screw is connected between the fixing protrusion 15 and the rigid base plate 2; during operation, the operator can place the placement box 11 on the top of the rigid base plate 2 through the screw and the fixing protrusion 15, place a desiccant inside the placement box 11, and replace the desiccant inside the placement box 11 regularly, thereby keeping the rigid top plate 1 and the rigid base plate 2 dry for a long time; this step, by placing a desiccant in the placement box 11, ensures the long-term dryness inside the rubber support, thereby slowing down the aging rate of the rubber pad body 3 and the high-strength spring 6, and extending the service life of the rubber support.
[0029] like Figure 4 and Figure 5 As shown, adhesive pieces 12 are fixed to the top and bottom of the rubber pad body 3; hemispherical holes 13 are opened on the surface of the adhesive pieces 12, and multiple hemispherical holes 13 are arranged in a linear array; during operation, the adhesive pieces 12 fixed to the top and bottom of the rubber pad body 3 contact the bottom of the rigid top plate 1 and the top of the rigid bottom plate 2 respectively. After the rubber support is installed, with the removal of the supporting equipment, the two hemispherical holes 13 begin to bear stress and undergo compression deformation. Multiple hemispherical holes 13 on the surface of the adhesive pieces 12 deform simultaneously under the action of the rigid top plate 1 and the rigid bottom plate 2. This step increases the friction between the rubber pad body 3 and the rigid top plate 1 and the rigid bottom plate 2 by fixing the adhesive pieces 12 to the top and bottom of the rubber pad body 3 and opening hemispherical holes 13 on the surface of the adhesive pieces 12, which helps to prevent the rubber pad body 3 from sliding out between the rigid top plate 1 and the rigid bottom plate 2, and enhances the stability of the rubber support.
[0030] like Figure 4 and Figure 5 As shown, the surface of the adhesive sheet 12 is provided with exhaust grooves 14, which are opened corresponding to the hemispherical holes 13, and multiple exhaust grooves 14 are arranged in a linear array. During operation, as the adhesive sheet 12 deforms, the air originally inside the adhesive sheet 12 will be compressed, and this air can be naturally discharged through the multiple linearly arrayed exhaust grooves 14. This step discharges the high-pressure gas on the surface of the adhesive sheet 12 by setting the exhaust grooves 14, avoiding damage to the adhesive sheet 12 and the rubber pad body 3 by a small amount of high pressure, which is beneficial to protecting the structural stability of the adhesive sheet 12 and the rubber pad body 3 and reducing safety hazards.
[0031] like Figure 5As shown, a limiting ring 18 is fixed to the top of the rigid base plate 2, and the limiting ring 18 is set to correspond to the size of the rubber pad body 3 and the adhesive sheet 12. During operation, the size of the limiting ring 18 is larger than the size of the rubber pad body 3 and the adhesive sheet 12, and the rubber pad body 3 and the rigid base plate 2 can deform inside the limiting ring 18. In the operation of replacing the rubber pad body 3, the operator can use the limiting ring 18 to position the rubber pad body 3. This step, by setting the limiting ring 18 to restrict the position of the rubber pad body 3 and assisting the operator in positioning the limiting ring 18, helps to prevent the rubber pad body 3 from sliding out under force, thus enhancing the stability of the rubber support.
[0032] During operation, the rigid top plate 1 is in close contact with the bridge body, and the rigid bottom plate 2 is in close contact with the piers. Whenever the rigid top plate 1 bears a load from the bridge body, the load from the bridge body is transmitted sequentially through the rigid top plate 1, the rubber pad body 3, and the rigid bottom plate 2 to the piers, and finally the piers transmit all the load and their own weight to the ground. During the force transmission process, if the bridge body is subjected to tangential stress, this stress is also transmitted among the rigid top plate 1, the rubber pad body 3, and the rigid bottom plate 2. Whenever these three parts are subjected to tangential force or instantaneous longitudinal force from the bridge body, the rubber pad body 3 located between the rigid top plate 1 and the rigid bottom plate 2 absorbs such stress through its own deformation. Multiple high-strength springs 6 located between the rigid top plate 1 and the rigid bottom plate 2... The fixing rings 16, limiting shafts 5, and fixing grooves at both ends of the rubber pad 1 and 2 apply tension to the rigid top plate 1 and rigid bottom plate 2. Whenever the rubber pad body 3 deforms and tilts, the rigid top plate 1 and rigid bottom plate 2 tilt simultaneously. Multiple high-strength springs 6 located between the rigid top plate 1 and rigid bottom plate 2 will be stretched, thereby outputting a greater tension to the rigid top plate 1 and rigid bottom plate 2. This allows the tilt to return to its original position after the stress disappears. The bottom of the rubber water barrier 7 is in close contact with the top of the rubber water barrier block 8 due to both gravity and its own shape. Except for human factors, the rubber water barrier 7 and the rubber water barrier block 8 can maintain a close contact for a long time, thus isolating rainwater, stagnant water, and other external water sources, keeping the internal space between the rigid top plate 1 and rigid bottom plate 2 dry. To mitigate the impact of moisture on components such as the high-strength spring 6 and the rubber pad body 3, and to maintain the normal operation of each component, whenever it is necessary to replace the rubber pad body 3 between the rigid top plate 1 and the rigid bottom plate 2, workers can first remove multiple bolts 17 to separate the rubber water curtain 7 from the rubber water-blocking block 8, and then carry out the replacement of the rubber pad body 3. The rigid bottom plate 2 is connected to the pier through multiple fixing rods 9 at its bottom, and the rigid top plate 1 is connected to the bridge body through multiple fixing rods 9 at its top. During construction, the construction personnel should place the rubber bearing on the horizontal platform at the top of the pier during the pier construction stage, and connect the multiple fixing rods 9 at the bottom of the rigid bottom plate 2 and the fixing blocks 10 at the ends of the multiple fixing rods 9 to the steel reinforcement inside the platform. Alternatively, the fixing rods 9 at the bottom of the rigid base plate 2 can be installed inside the mold inside the platform. During the bridge construction phase, construction workers should also connect the rigid top plate 1 to the steel structure of the bridge body through multiple fixing rods 9 and fixing blocks 10 on the top of the rigid top plate 1, or install the fixing rods 9 on the top of the rigid top plate 1 into the mold inside the bridge body. Workers can use screws and fixing protrusions 15 to set up a placement box 11 on the top of the rigid base plate 2, place desiccant inside the placement box 11, and replace the desiccant inside the placement box 11 regularly to keep the rigid top plate 1 and rigid base plate 2 dry for a long time. The adhesive pieces 12 fixed to the top and bottom of the rubber pad body 3 respectively contact the bottom of the rigid top plate 1 and the top of the rigid base plate 2. After the rubber bearing is installed,With the removal of the supporting equipment, the two hemispherical holes 13 begin to bear stress and undergo compression deformation. Multiple hemispherical holes 13 on the surface of the adhesive sheet 12 deform simultaneously under the action of the rigid top plate 1 and the rigid bottom plate 2. As the adhesive sheet 12 deforms, the air originally inside it is compressed and can be naturally discharged through multiple linearly distributed exhaust channels 14. The size of the limiting ring 18 is larger than the size of the rubber pad body 3 and the adhesive sheet 12, allowing the rubber pad body 3 and the rigid bottom plate 2 to deform within the limiting ring 18. During the replacement of the rubber pad body 3, workers can use the limiting ring 18 to position the rubber pad body 3.
