Detailed Implementation

[0030] 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.

[0031] Please see Figures 1-4 This utility model provides a technical solution: a high-efficiency U-shaped rib bridge deck reinforcement joint structure, including a first movable plate 1 and a second movable plate 2. The side walls of the first movable plate 1 and the second movable plate 2 are provided with teeth, which are mutually adapted to each other. The upper surfaces of the first movable plate 1 and the second movable plate 2 are provided with protective components 4, and the lower surfaces of the first movable plate 1 and the second movable plate 2 are provided with installation components 5.

[0032] The protective component 4 includes a groove 41. The upper surfaces of the first movable plate 1 and the second movable plate 2 are both provided with grooves 41. A movable plate 42 is slidably installed on the inner wall of the bottom surface of the groove 41. One side of the movable plate 42 extends to the outside of the first movable plate 1 and the second movable plate 2. A connecting rod 44 is fixedly installed on the side wall of the movable plate 42. A top block 43 is fixedly installed on the upper surface of the movable plate 42. The side wall of the top block 43 is inclined. A lifting column 45 is slidably installed on the inner surface of the groove 41. A portion of the lifting column 45 extends to the outside of the groove 41. A protrusion 46 is fixedly installed on the lower surface of the lifting column 45. The side wall of the protrusion 46 is inclined. The top block 43 and the protrusion 46 are mutually adapted. A rubber cover 3 is fixedly installed on the upper surface of the first movable plate 1. One end of the rubber cover 3 is fixedly connected to the upper surface of the second movable plate 2.

[0033] The specific implementation is as follows: When the bridge deck expands, the distance between the first movable plate 1 and the second movable plate 2 gradually increases. At this time, under the action of the connecting rod 44, the moving plate 42 will move outward from the groove 41. When the moving plate 42 moves in the groove 41, it will drive the top block 43 to move synchronously. The lifting column 45 will move outward from the groove 41 under the action of the protrusion 46. Since the side walls of the top block 43 and the protrusion 46 are both set in an inclined shape, when the top block 43 moves, the two inclined surfaces will slide, thereby pushing the protrusion 46 upward from the groove 41. This causes the lifting column 45 to move to the outside of the groove 41. When the distance between the first movable plate 1 and the second movable plate 2 increases, the rubber cover 3 will block the teeth. In the vehicle joint structure, the two lifting columns 45 will lift the wheel. At this time, the wheel does not contact the teeth on the first movable plate 1 and the second movable plate 2 or the contact surface is low, thereby reducing the pressure of the vehicle on the first movable plate 1 and the second movable plate 2. The rubber cover 3 can also block rainwater in rainy weather, preventing rainwater from flowing into the gap through the teeth of the first movable plate 1 and the second movable plate 2.

[0034] The mounting assembly 5 includes a fixing plate 51. The lower surfaces of the first movable plate 1 and the second movable plate 2 are both fixedly mounted with the fixing plate 51. Several positioning plates 52 are fixedly mounted on the side wall of the fixing plate 51. U-shaped ribs 53 are fixedly mounted on the side wall of the positioning plate 52. An mounting plate 54 is fixedly mounted on the upper surface of the positioning plate 52. A damping shock absorber 55 and a rubber tube 56 are fixedly mounted on the upper surface of the mounting plate 54. The upper surfaces of the damping shock absorber 55 and the rubber tube 56 are fixedly connected to the lower surfaces of the first movable plate 1 and the second movable plate 2. Sound-reducing cotton is fixedly mounted on the inner wall of the rubber tube 56. A limiting groove 6 is provided on the side wall of the fixing plate 51. One end of the connecting rod 44 is slidably connected to the inner wall of the limiting groove 6. The connecting rod 44 only moves up and down within the limiting groove 6 and will not disengage from the limiting groove 6.

[0035] The specific implementation method is as follows: U-shaped reinforcement 53 and positioning plate 52 are placed into the concrete in the gap of the bridge deck. As the concrete gradually dries, the positioning plate 52 is fixed by fixing the U-shaped reinforcement 53. Thus, under the action of fixing plate 51 and mounting plate 54, the first movable plate 1 and the second movable plate 2 are fixed in the gap of the bridge deck. At this time, the teeth of the first movable plate 1 and the second movable plate 2 are staggered. When the vehicle comes into contact with the first movable plate 1 and the second movable plate 2, the first movable plate 1 and the second movable plate 2 will drop. At this time, the damping shock absorber 55 and the rubber tube 56 can reduce the drop distance of the first movable plate 1 and the second movable plate 2. At the same time, the sound-dampening cotton in the rubber tube 56 can absorb the noise generated when the wheel runs over the joint structure, thereby achieving the noise reduction effect of the joint structure.

[0036] Working principle: The U-shaped reinforcing bar 53 is placed into the concrete at the gap in the bridge deck. As the concrete gradually dries, it fixes the positioning plate 52 by securing the U-shaped reinforcing bar 53. Under the action of the fixing plate 51 and the mounting plate 54, the first movable plate 1 and the second movable plate 2 are fixed at the gap in the bridge deck. When the bridge deck expands, the distance between the first movable plate 1 and the second movable plate 2 gradually increases. At this time, under the action of the connecting rod 44, the moving plate 42 moves outward from the groove 41. When the moving plate 42 moves within the groove 41, it drives the top block 43 to move synchronously. Under the action of the protrusion 46, the lifting column 45 moves outward from the groove 41, thus moving the lifting column 45 to the outside of the groove 41. When the distance between the first movable plate 1 and the second movable plate 2 increases, the rubber cover 3 will block the teeth. When the vehicle joint structure is in place, the two lifting columns 45 will lift the wheel. At this time, the wheel does not contact the teeth on the first movable plate 1 and the second movable plate 2 or the contact surface is low, thereby reducing the pressure of the vehicle on the first movable plate 1 and the second movable plate 2. At the same time, when the vehicle contacts the first movable plate 1 and the second movable plate 2, the first movable plate 1 and the second movable plate 2 will descend. At this time, the damping shock absorber 55 and the rubber tube 56 can reduce the descent distance of the first movable plate 1 and the second movable plate 2. Meanwhile, the sound-absorbing cotton in the rubber tube 56 can absorb the noise generated when the wheel passes over the joint structure.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
