Description

Technical Field

[0002] Concrete bridge reinforcement is an engineering approach primarily used for old and damaged bridges, with the core objective of significantly improving their load-bearing capacity and durability. Before implementation, a precise diagnosis of the bridge's defects is necessary, followed by the selection of a suitable reinforcement scheme. Ultimately, this ensures that the reinforced bridge fully complies with current load standards and adequately meets long-term safe passage requirements.

[0003] The concrete bridge reinforcement structures currently in use utilize the high strength of materials to work synergistically with the original structure to enhance bending and shear resistance. For example, high-strength materials such as steel plates and carbon fiber cloth are directly added inside the bridge, which effectively ensures the structural stability of the bridge under load, while delaying concrete deterioration, extending the overall service life of the bridge, and meeting the requirements for safe passage.

[0004] Current concrete bridge reinforcement structures, while improving bridge stability and ensuring traffic safety and service life by directly adding various high-strength materials inside the bridge, require a large amount of high-strength materials and cannot be flexibly adjusted. Therefore, a concrete bridge reinforcement structure is proposed to solve the above problems. Utility Model Content

[0033] 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.

[0034] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a concrete bridge reinforcement structure, including a bridge column 1, a bridge body 6 fixedly connected to the top of the bridge column 1, providing main support to the bridge body 6 through the bridge column 1, a connecting block 2 fixedly connected to the inner side of the bridge column 1, and rotating rods 12 rotatably connected to both sides of the connecting block 2, connecting the external structure to the outside of the connecting block 2 through the rotating rods 12, and then connecting to the outside of the bridge column 1 through the connecting block 2, with a telescopic component installed inside the rotating rod 12, the reinforcement structure being supported and reinforced by the telescopic component, a telescopic rod 3 slidably connected to the middle of the rotating rod 12, and a support plate 7 rotatably connected to the top of the telescopic rod 3, the support plate 7 being moved upward by the telescopic rod 3 for support and reinforcement, and a lifting component installed in the middle of the connecting block 2, the connecting block 2 driving the telescopic component to rise and fall through the lifting component, and the support position of the support plate 7 being adjusted through the extension and retraction of the telescopic rod 3;

[0035] The telescopic assembly includes a worm gear 18, which is rotatably connected to the inner side of the rotating rod 12. The telescopic assembly provides total power through the rotation of the worm gear 18. A knob 13 is fixedly connected to the outer side of the worm gear 18, which allows the worm gear 18 to be rotated more conveniently and effortlessly. A worm wheel 20 is rotatably connected inside the rotating rod 12. The worm wheel 20 meshes with the worm gear 18. Through meshing with the worm gear 18, the worm wheel 20 drives the worm gear 18 to rotate. A lead screw 21 is threadedly connected to the middle of the worm wheel 20. The lead screw 21 is rotatably connected to the bottom of the telescopic rod 3. The lead screw 21 rotates under the action of the worm wheel 20, ultimately driving the telescopic rod 3 to move upward.

[0036] Reference Figure 3 and Figure 4 The lifting assembly includes a threaded rod 17, which is threadedly connected to the middle of the connecting block 2. The rotation of the threaded rod 17 drives the connecting block 2 to move up and down. A screw 14 is fixedly connected to the bottom of the threaded rod 17. Under the action of the screw 14, the threaded rod 17 can be rotated more easily and effortlessly. Two limiting plates 15 are fixedly connected inside the bridge column 1. The threaded rod 17 is rotatably connected to the middle of the two limiting plates 15. The limiting plates 15 restrict the up and down movement of the threaded rod 17, so that the threaded rod 17 can only rotate. Two limiting blocks 22 are fixedly connected inside the rotating rod 12. The worm gear 20 is located between the two limiting blocks 22. The two limiting blocks 22 restrict the displacement of the worm gear 20, so that the worm gear 20 can rotate more stably.

[0037] Reference Figure 2 , Figure 3 and Figure 5The threaded rod 17 has a slot 19 on its outer side. The limiting plate 15 is engaged with the slot 19. The limiting plate 15 achieves the limiting effect by engaging with the slot 19. The connecting block 2 is fixedly connected to the outer side of the fixing block 16. The rotating rod 12 is rotatably connected inside the fixing block 16. The fixing block 16 provides the rotating rod 12 with the rotation conditions. The connecting block 2 is fixedly connected to the outer side of the connecting block 2. The rotating rod 12 is fixedly connected to the outer side of the locking block 2. The locking block 14 and the locking block 29 are rotatably connected to the connecting rod 12. The connecting rod 5 connects and restricts the rotation space of the rotating rod 12. The bottom of the support plate 7 is fixedly connected to the connecting block 8. The telescopic rod 3 is rotatably connected inside the connecting block 8. The bridge column 1 has a strip groove 10 inside. The connecting block 2 moves stably inside the bridge column 1 through the strip groove 10. The bottom of the bridge column 1 is fixedly connected to the base 11. The base 11 increases the support and stability of the bridge.

[0038] Working principle: First, rotate screw 14. Under the action of screw 14, threaded rod 17 drives connecting block 2 to slide up and down inside bridge column 1. When support plate 7 is adjusted to a suitable angle by connecting block 2, rotate screw 13. Under the rotation of screw 13, worm gear 18 drives worm wheel 20 to rotate. Worm wheel 20 drives lead screw 21 to rotate. At this time, lead screw 21 pushes telescopic rod 3 while rotating. Lead screw 21 extends and retracts along the angle between rotating rod 12 and connecting block 2. Under the push of lead screw 21, telescopic rod 3 drives support plate 7 to move outward along the adjusted angle until it moves to the corresponding position at the bottom of bridge body 6, thus stably supporting and reinforcing bridge body 6.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
