Description

Technical Field

[0001] This utility model relates to the field of bridge maintenance technology, and in particular to a bridge pier reinforcement structure. Background Technology

[0002] Traditional reinforced concrete bridge piers are prone to damage such as peeling of the protective layer, cracking, and steel corrosion under corrosive environments like the ocean, improper construction, localized collisions, and water erosion, leading to reduced pier durability. To eliminate traffic safety hazards, extend the service life of bridges, or enable bridge piers to meet greater load-bearing requirements, it is necessary to reinforce damaged bridge piers.

[0003] Currently, most bridge pier reinforcement structures typically use an arc-shaped plate attached to the surface of the pier at one end for fixation, and then the other end is fixedly connected to the bridge to achieve reinforcement. However, the arc-shaped plate in the bridge pier reinforcement structure is usually not removable. Therefore, a bridge pier reinforcement structure can only be used for reinforcement of bridge piers with a matching diameter, which has certain limitations. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a bridge pier reinforcement structure to address the above-mentioned problems.

[0005] The technical solution adopted in this utility model is: a bridge pier reinforcement structure, disposed between the bottom of the bridge and the outer wall of the pier, comprising:

[0006] The reinforcement component is detachably installed on the outer wall of the damaged part of the pier. It is adapted to the diameter of the pier and can form a ring-shaped fixation for the pier. The outer wall of the reinforcement component is detachably provided with symmetrically arranged disassembly plates.

[0007] The support components are symmetrically arranged on both sides of the bottom of the bridge. One end is detachably connected to the bottom of the bridge, and the other end is hinged to a frame that can slide and engage with the detachable insert plate. The support components can provide partial lateral support to the reinforcement components.

[0008] The positioning component, located inside the insert frame, is used to lock or unlock the insert plate when it is disassembled and inserted into the insert frame.

[0009] Through the above-mentioned technical means, since the reinforcement components adopt a detachable installation method, appropriate reinforcement components can be selected for piers of different diameters, which improves the versatility of the reinforcement components. The reinforcement components form a ring-shaped fixation for the piers. The reinforcement components are equipped with detachable insert plates, and the support components located between the bottom of the bridge and the outer wall of the pier are equipped with insert frames. The insert frames and detachable insert plates can be inserted and matched to form a preliminary fixation, and are further locked by positioning components, which improves the stability of the reinforcement. The detachable installation of the positioning components ensures that the reinforcement components can also be replaced.

[0010] In some embodiments, the positioning component includes a movable plate, a positioning plate, and an adjusting member. The top and bottom of the disassembly insert plate are provided with positioning grooves. The insert frame is provided with an adjusting member inside. The two output ends of the adjusting member pass through the top and bottom side walls of the insert frame respectively and are respectively connected to the movable plate. The side wall of the movable plate is connected to a positioning plate that can be inserted and cooperate with the positioning groove. The adjusting member is used to control the movable plates at both ends to retract inward or extend outward synchronously, so that the positioning plate on the movable plate and the positioning groove can be correspondingly engaged and limited or disengaged.

[0011] In some embodiments, the adjusting component includes a bidirectional lead screw, threaded blocks, a push plate, and a driving component. The bidirectional lead screw is rotatably mounted inside the insert frame via a pair of bearings. The two ends of the outer wall of the bidirectional lead screw have mutually opposing threads. The outer wall of the bidirectional lead screw is fitted with mutually symmetrical threaded blocks. The opposite side of the threaded blocks is connected to a push plate that penetrates the side wall of the insert frame and slides relative to it. The end of the push plate away from the threaded blocks is connected to a moving plate. The push plate and the positioning plate are located on the same side of the moving plate. The insert frame also has a driving component, which is connected to the bidirectional lead screw in a transmission connection. The driving component is used to drive the bidirectional lead screw to rotate around its own axis, so that the pair of threaded blocks move towards each other or away from each other.

[0012] In some embodiments, the driving component includes a first bevel gear, a second bevel gear, a rotating rod, and a cross-shaped rotating block. The first bevel gear is sleeved at the middle position of the outer wall of the bidirectional lead screw. The rotating rod passes through the side wall of the insertion frame and is rotatably mounted on the side wall of the insertion frame via a bearing. The end of the rotating rod protruding from the insertion frame is connected to the cross-shaped rotating block. The end of the rotating rod located inside the insertion frame is connected to the second bevel gear, and the second bevel gear meshes with the first bevel gear.

[0013] In some embodiments, the inner wall of the insert frame is symmetrically provided with limiting grooves, and the side walls of the threaded blocks are all connected with limiting sliders that can be embedded in the corresponding limiting grooves. The limiting sliders are slidably connected to the corresponding limiting grooves, so that the limiting sliders can slide along the axial direction of the bidirectional lead screw in the limiting grooves.

[0014] In some embodiments, the support assembly includes a mounting plate, a first connecting block, a connecting plate, a second connecting block, and a connector. One end of the connecting plate has a first notch, in which the first connecting block is rotatably connected. The first connecting block is connected to the mounting plate. The other end of the connecting plate has a second notch, in which the second connecting block is rotatably connected. The second connecting block is connected to the insert frame. The mounting plate has mounting holes, and the connector is used to pass through the mounting holes to fix the mounting plate to the bottom of the bridge.

[0015] In some embodiments, the reinforcement component includes an arc-shaped plate, a butt plate, and a connector. Both ends of the arc-shaped plate are connected to the butt plate, and each butt plate is provided with a mounting hole. A pair of arc-shaped plates can cooperate to fix the outer wall of the pier in a wrap-around manner. The butt plates and mounting holes of the pair of arc-shaped plates correspond to each other, and the connector can pass through the mounting holes to fix the pair of arc-shaped plates.

[0016] The beneficial effects of this utility model are:

[0017] 1. By using a detachable installation method for the reinforcement components, only the reinforcement components need to be replaced to adapt to piers of different diameters. The reinforcement components form a ring-shaped fixing structure around the outer wall of the pier. The bottom of the bridge is connected to the support components. By inserting the detachable insert plate on the reinforcement component into the insert frame on the support component, the reinforcement component and the support component are initially and quickly fixed. Then, the positioning component is used to lock or unlock the detachable insert plate in the inserted state to further fix the detachable insert plate and the insert frame, which improves the stability of the connection and ensures that the connection strength of the insert structure is consistent for piers of different diameters. This improves the adaptability of the pier reinforcement structure to piers of different diameters. Attached Figure Description

[0028] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below with reference to specific embodiments.

[0029] Combination Figures 1 to 5 As shown, this embodiment is a bridge pier reinforcement structure, including a reinforcement component, a support component, and a positioning component. The reinforcement component is detachably installed on the outer wall of the damaged area of ​​the bridge pier 11. The diameter of the reinforcement component is adapted to that of the bridge pier 11, and the reinforcement component can form a circumferential fixation for the bridge pier 11. The outer wall of the reinforcement component is detachably provided with a disassembly plate 14, which is symmetrically arranged on both sides of the reinforcement component. Support components are symmetrically arranged on both sides of the bottom of the bridge 1. One end of the support component is detachably connected to the bottom of the bridge 1, and the other end of the support component is hinged to a frame 8. The frame 8 and the disassembly plate 14 can slide and engage, and the support component can provide partial lateral support for the reinforcement component. The positioning component is located inside the frame 8. When the frame 8 and the disassembly plate 14 are engaged, the positioning component can lock or unlock the disassembly plate 14.

[0030] In some implementation schemes, such as Figure 1 and Figure 5As shown, the reinforcement assembly includes an arc-shaped plate 9, a mating plate 10, and a connector. Both ends of the arc-shaped plate 9 are connected to the mating plate 10, and each mating plate 10 has mounting holes. A pair of arc-shaped plates 9 can cooperate to encircle and fix the outer wall of the pier 11. When a pair of arc-shaped plates 9 are engaged, the mating plates 10 on both sides and the mounting holes correspond. The connector can pass through the mounting holes to fix the pair of arc-shaped plates 9. Specifically, in this embodiment, the connector uses bolts or other connecting components.

[0031] In some implementation schemes, such as Figure 1 and Figure 2 As shown, the support assembly includes a mounting plate 2, a first connecting block 3, a connecting plate 4, a second connecting block 5, and a connector. One end of the connecting plate 4 has a first notch 12, within which the first connecting block 3 is rotatably connected. The first connecting block 3 is connected to the mounting plate 2. The other end of the connecting plate 4 has a second notch 13, within which the second connecting block 5 is rotatably connected. The second connecting block 5 is connected to a insert frame 8. The mounting plate 2 has mounting holes, through which the connector is used to fix the mounting plate 2 to the bottom of the bridge 1. Specifically, in this embodiment, the connector uses bolts or other connecting components.

[0032] The support components employ a multi-segment hinged structure, allowing for flexible adjustment of angle and position to adapt to different bridge bottom shapes and dimensions. Furthermore, the use of mounting holes and connectors facilitates rapid on-site installation and securing, improving construction efficiency.

[0033] In some implementation schemes, such as Figure 2 and Figure 3 As shown, the positioning assembly includes a movable plate 6, a positioning plate 16, and an adjusting component. Positioning slots 17 are provided at the top and bottom of the disassembly insert plate 14. An adjusting component is located inside the insert frame 8. The two output ends of the adjusting component penetrate the top and bottom side walls of the insert frame 8, respectively. The output ends of the adjusting component are correspondingly connected to the movable plate 6. The side wall of the movable plate 6 is fixedly connected to the positioning plate 16, which can be inserted and engaged with the positioning slot 17. The adjusting component controls the movable plates 6 at both ends to simultaneously retract inward or extend outward, allowing the positioning plate 16 on the movable plate 6 to engage with the positioning slot 17 for locking or to disengage from the positioning slot 17 for contact locking.

[0034] Furthermore, such as Figure 3As shown, the adjusting component includes a bidirectional lead screw 19, threaded blocks 18, a push plate 15, and a driving component. Both ends of the bidirectional lead screw 19 are rotatably mounted inside the insert frame 8 via bearings. The outer walls of the bidirectional lead screw 19 have opposing threads at both ends, and symmetrically fitted threaded blocks 18 are fitted onto the outer walls of the bidirectional lead screw 19. A push plate 15, penetrating the side wall of the insert frame 8, is fixedly connected to the opposite side of the threaded blocks 18. The push plate 15 is slidably connected to the penetrating portion of the insert frame 8. A movable plate 6 located outside the insert frame 8 is fixedly connected to the end of the push plate 15 away from the threaded blocks 18. The push plate 15 and the positioning plate 16 are located on the same side of the movable plate 6. A driving component is also provided inside the insert frame 8. The driving component is connected to the bidirectional lead screw 19 and drives the bidirectional lead screw 19 to rotate around its own axis, causing the pair of threaded blocks 18 to move towards or away from each other.

[0035] Furthermore, such as Figure 3 As shown, the inner wall of the insert frame 8 is symmetrically provided with limiting grooves 20 parallel to the axial direction of the bidirectional lead screw 19. The side walls of the threaded block 18 are all connected with limiting sliders 21 that can be embedded in the corresponding limiting grooves 20. The limiting sliders 21 are slidably connected to the corresponding limiting grooves 20, so that when the threaded block 18 moves on the bidirectional lead screw 19, the threaded block 18 can drive the limiting sliders 21 to slide along the axial direction of the bidirectional lead screw 19 in the limiting grooves 20.

[0036] The cooperation between the limiting slide groove 20 and the limiting slider 21 ensures the linear motion stability of the threaded block 18 along the axial direction of the bidirectional lead screw 19, and prevents the threaded block 18 from deviating or jamming during movement.

[0037] Furthermore, such as Figure 4 As shown, the driving component includes a first bevel gear 22, a second bevel gear 23, a rotating rod 24, and a cross-shaped rotating block 7. The first bevel gear 22 is sleeved at the middle position of the outer wall of the bidirectional lead screw 19. The rotating rod 24 passes through the side wall of the insert frame 8 and is rotatably mounted on the side wall of the insert frame 8 via a bearing. The end of the rotating rod 24 protruding from the insert frame 8 is connected to the cross-shaped rotating block 7. The end of the rotating rod 24 located inside the insert frame 8 is connected to the second bevel gear 23. The second bevel gear 23 meshes with the first bevel gear 22.

[0038] The operator can easily drive the internal bidirectional lead screw 19 to rotate through the external cross-shaped rotating block 7, thereby reducing the difficulty of operation and improving work efficiency.

[0039] The implementation principle of a bridge pier reinforcement structure is as follows:

[0040] The operator provides initial power input to the entire structure by rotating the external cross-shaped rotating block 7. The cross-shaped rotating block 7 is connected to the end of the rotating rod 24, which passes through the side wall of the insert frame 8 and is mounted on the insert frame 8 via bearings, ensuring that it can rotate freely without displacement. A second bevel gear 23 is connected to one end of the rotating rod 24 inside the insert frame 8. When the rotating rod 24 is rotated, it drives the second bevel gear 23 to rotate synchronously. The second bevel gear 23 meshes with the first bevel gear 22 in the middle of the double-acting lead screw 19. Therefore, the rotation of the second bevel gear 23 drives the first bevel gear 22 and the double-acting lead screw 19 to rotate around their own axis.

[0041] Since the two-way lead screw 19 has threads that are opposite to each other at both ends, when it starts to rotate, the threaded blocks 18 fitted on both ends of its outer wall will move in the opposite direction of the lead screw (depending on the direction of rotation).

[0042] As the threaded blocks 18 move, their respective connected push plates 15 also move. The push plates 15 pass through and slide relative to the side wall of the insert frame 8, ensuring stability during movement. The other end of the push plate 15 is connected to a moving plate 6, which causes the moving plate 6 to extend outward synchronously.

[0043] The positioning plate 16 on the movable plate 6 moves accordingly and can engage with the positioning grooves 17 opened at the top and bottom of the disassembly insert plate 14 to release the locking limit, thus completing the separation of the positioning plate 16 from the positioning grooves 17. Then the disassembly insert plate 14 can be removed from the insert frame 8, and the arc plate 9 can be replaced. The arc plate 9 that is compatible with the diameter of the pier 11 can be replaced and installed.

[0044] During installation, the disassembly plate 14 is inserted into the insert frame 8, and the cross-shaped rotating block 7 is reversed. Under the action of the rotating rod 24, the first bevel gear 22, and the second bevel gear 23, the bidirectional lead screw 19 can be reversed, causing the two threaded blocks 18 to move towards each other, and the two moving plates 6 to move further towards each other. The positioning plate 16 slides into the positioning groove 17, completing the installation of the arc plate 9.

[0045] Then, the two curved plates 9 are attached to the surface of the pier 11, making them apical. The two apical plates 9 are then bolted together through the mounting holes on the apical plate 10, thus fixing the curved plates 9 to the surface of the pier 11. Then, the mounting plate 2 is bolted to the bottom of the bridge 1 through the mounting holes on the mounting plate 2, completing the installation and use of the entire pier reinforcement structure. The pier reinforcement structure in this application allows for the disassembly and replacement of the curved plates. Replacing the curved plates with those of different curvatures makes it suitable for piers of various diameters, demonstrating high practicality and applicability.

[0046] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
