Description

Technical Field

[0001] The utility model relates to the technical field of road and bridge reinforcement, in particular to a road and bridge crack reinforcement structure. Background Art

[0002] Roads and bridges are common infrastructure. After a period of use, cracks will appear on the road bridges themselves. If the cracks are not treated, the cracks will continue to widen and lengthen due to temperature differences, weathering, etc., affecting the quality and safety of the road bridges. The cracks in road bridges are sealed and reinforced by filling with sealants and other measures.

[0003] The grouting fillers in the cracks of road bridges are directly exposed to the outside. The crack grouting fillers will age and wear out prematurely due to temperature and weathering, shortening their service life. Due to the change in temperature, the grouting fillers and the surrounding roads and bridges shrink to different extents. The grouting fillers and the surrounding roads and bridges can easily separate, and the cracks may also expand.

[0004] Therefore, it is particularly important to design a road bridge crack reinforcement structure to solve the above defects. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model designs a road bridge crack reinforcement structure, which aims to solve the technical problems that after the road bridge cracks are repaired under the existing technology, the poured filler is directly exposed to the outside, resulting in a shortened service life, and is prone to separation, which causes the cracks to expand.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A road bridge crack reinforcement structure includes a cover plate mounted on the top of the bridge crack, wherein locking mechanisms are installed at both the front and rear ends of the cover plate, and multiple sets of reinforcement plates are movably engaged with the top of the cover plate. Multiple sets of reinforcement mechanisms are installed on one side of the cover plate located inside the bridge crack.

[0008] The reinforcement mechanism includes a rotating shaft rotatably connected to the inside of the cover plate, the bottom end of the rotating shaft is rotatably connected to a locking block, the outer side of the rotating shaft is threadedly connected to a connecting plate, both ends of the connecting plate are fixedly connected to sliding rods, the outer sides of the two groups of sliding rods are sleeved with a first spring, the bottom ends of the two groups of sliding rods are slidably connected to sliding sleeves, the opposite sides of the two groups of sliding sleeves are rotatably connected to support rods, and the ends of the two groups of support rods away from the sliding sleeves are rotatably connected to the inner support plate.

[0009] As a preferred solution of the present invention, a slot is provided inside the bridge crack at a position corresponding to the locking block, and a card block is slidably connected to the left and right sides of the locking block. A second spring is movably installed inside the locking block and between the two groups of locking blocks, and a card slot is provided inside the slot at a position corresponding to the card block.

[0010] As a preferred solution of the present invention, the connecting plate is threadedly connected to the rotating shaft through a threaded sleeve, and the bottom end of the sliding rod is fixedly connected to a limiting block at the bottom of the sliding sleeve.

[0011] As a preferred solution of the present invention, the cover plate is installed on the top of the bridge crack by framing a groove, and a plurality of groups of pouring holes are provided inside the cover plate.

[0012] As a preferred solution of the present invention, the locking mechanism includes movable grooves opened at the front and rear ends of the cover plate, and the left and right ends of the movable groove are slidably connected to locking plug plates. A third spring is fixedly connected to the inside of the movable groove and located between the two groups of locking plug plates. The top end of the movable groove is threadedly connected to a threaded column, and the bottom end of the threaded column is rotatably connected to an extrusion block located between the two groups of locking plug plates.

[0013] As a preferred solution of the present invention, a locking groove is provided at a position inside the cover plate corresponding to the locking plug plate, and an oblique groove adapted for use with the extrusion block is provided on opposite sides of the two sets of locking plug plates.

In the present invention, the cover plate, the locking mechanism and the reinforcement plate are designed in coordination, and the cover plate is erected on the top of the bridge crack and fixed by the locking mechanism. The inside of the bridge crack is poured with filler through the pouring hole.

[0025] The following will combine the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Example

[0026] See also Figures 1-6 , the utility model provides a technical solution:

[0027] A road bridge crack reinforcement structure includes a cover plate 2 erected on the top of a bridge crack 1, locking mechanisms 3 are installed at the front and rear ends of the cover plate 2, multiple groups of reinforcement plates 4 are movably connected to the top of the cover plate 2, and multiple groups of reinforcement mechanisms 5 are installed on one side of the cover plate 2 located inside the bridge crack 1.

[0028] First, in this embodiment, the specific structure of the reinforcement mechanism 5 is as follows:

[0029] The reinforcing mechanism 5 includes a rotating shaft 501 rotatably connected to the inside of the cover plate 2, the bottom end of the rotating shaft 501 is rotatably connected to a locking block 502, the outer side of the rotating shaft 501 is threadedly connected to a connecting plate 503, both ends of the connecting plate 503 are fixedly connected to sliding rods 504, the outer sides of the two groups of sliding rods 504 are sleeved with a first spring 505, the bottom ends of the two groups of sliding rods 504 are slidably connected to sliding sleeves 506, the opposite sides of the two groups of sliding sleeves 506 are rotatably connected to support rods 507, and the ends of the two groups of support rods 507 away from the sliding sleeves 506 are rotatably connected to the inner support plate 508. After the cover plate 2 is erected on the top of the bridge crack 1, it is fixed by the locking mechanism 3, and the locking block 502 at the bottom end of the rotating shaft 501 is stuck into the bottom end inside the bridge crack 1. Then, the rotating shaft 501 is rotated to lower the connecting plate 503, and the inner support plate 508 continues to press against the inner wall of the bridge crack 1. As the height of the connecting plate 503 is lowered, the sliding rod 504 is lowered accordingly, so that the sliding sleeve 506 slides on the outside of the sliding rod 504 and compresses the first spring 505. At the same time, the reaction force of the first spring 505 continues to push the sliding sleeve 506. Under the connection of the support rod 507, the inner support plate 508 is tightly pressed against the inner wall of the bridge crack 1, thereby reinforcing the inside of the bridge crack 1. Filler is poured into the inside of the bridge crack 1 through the cover plate 2. After the filler solidifies, the entire reinforcement mechanism 5 can also provide additional connection anchor points, thereby improving the tightness between the filler and the bridge crack 1 and reducing the risk of crack expansion.

[0030] Furthermore, a slot 509 is provided inside the bridge crack 1 at a position corresponding to the locking block 502, and a card block 510 is slidably connected to the left and right sides of the locking block 502. A second spring 511 is movably installed inside the locking block 502 and between the two groups of locking blocks 502. A card slot 512 is provided inside the slot 509 at a position corresponding to the card block 510. After the cover plate 2 is placed on the top of the bridge crack 1 and fixed, the locking block 502 is automatically inserted into the inside of the slot 509. When the locking block 502 is inserted, the card block 510 will first retract into the inside of the locking block 502. After the locking block 502 is inserted, the second spring 511 resets and pushes the card block 510 out, so that the card block 510 is stuck in the inside of the card slot 512, thereby fixing the locking block 502.

[0031] Then, the connecting plate 503 is threadedly connected to the rotating shaft 501 through the threaded sleeve 513, and the bottom end of the sliding rod 504 is fixedly connected to the limiting block 514 at the bottom of the sliding sleeve 506. The connecting plate 503 can move up and down when the rotating shaft 501 rotates under the connection of the threaded sleeve 513, and the bottom end of the sliding sleeve 506 is limited by the limiting block 514.

[0032] Furthermore, the cover plate 2 is erected on the top of the bridge crack 1 through the groove 201, and a plurality of pouring holes 202 are provided inside the cover plate 2. The cover plate 2 is erected on the top of the bridge crack 1 through the groove 201 for easy installation. After the cover plate 2 is installed and fixed and the reinforcement mechanism 5 reinforces the inside of the bridge crack 1, filler is poured into the inside of the bridge crack 1 through the pouring holes 202. After the filler solidifies, the top of the filler is protected by the cover plate 2, thereby increasing the service life of the filler. At the same time, the filler is sealed inside the bridge crack 1, further improving the tightness between the filler and the bridge crack 1, and reducing the risk of crack expansion.

[0033] The cam 308 is engaged with the first and second cams 309 and the second cams 310 are engaged with the first and second cams 311. When the cam 310 is engaged, the first and second cams 311 are engaged with the first and second cams 312. When the cam 310 is engaged, the first and second cams 313 are engaged with the first and second cams 314. When the cam 310 is engaged, the first and second cams 315 are engaged with the first and second cams 316. When the cam 310 is engaged, the first and second cams 317 are engaged with the first and second cams 318. When the cam 310 is engaged, the first and second cams 319 are engaged with the first and second cams 319. The spring 303 will pull the two sets of locking plugs 302 so that the locking plugs 302 are retracted into the inside of the movable groove 301. After the cover plate 2 is erected on the top of the bridge crack 1, the threaded column 304 is rotated to rotate it toward the inside of the movable groove 301, so that the extrusion block 305 is squeezed into between the two sets of locking plugs 302 through the inclined groove 307 until the two sets of locking plugs 302 are inserted into the inside of the locking groove 306, thereby facilitating the installation and fixing of the cover plate 2 on the top of the bridge crack 1, and then protecting its top through the cover plate 2 after the filler solidifies, thereby increasing the service life of the filler and sealing the filler inside the bridge crack 1, further improving the tightness between the filler and the bridge crack 1, and reducing the risk of crack expansion.

[0034] Finally, an embedded groove 401 is opened at a position inside the cover plate 2 corresponding to the reinforcement plate 4, and the internal thread of the reinforcement plate 4 is connected with multiple sets of mounting bolts 402. After the cover plate 2 is installed and fixed, the reinforcement plate 4 is installed on the top of the cover plate 2 through the embedded groove 401, and then installed and fixed with the mounting bolts 402. The outer side of the bridge crack 1 is further reinforced by multiple sets of reinforcement plates 4, further reducing the risk of crack expansion.

[0035] In this embodiment, the implementation scenario is specifically as follows: the cover plate 2 is set on the top of the bridge crack 1 and fixed by the locking mechanism 3, the locking block 502 at the bottom end of the rotating shaft 501 is stuck in the bottom end of the inside of the bridge crack 1, and then the rotating shaft 501 is rotated to lower the connecting plate 503, and the inner support plate 508 continues to press against the inner wall of the bridge crack 1. As the height of the connecting plate 503 is lowered, the sliding rod 504 is lowered accordingly, so that the sliding sleeve 506 slides on the outside of the sliding rod 504 and compresses the first spring 505. At the same time, the reaction force of the first spring 505 continues to push the sliding sleeve 506, and under the connection of the support rod 507, the inner support plate 508 is tightly pressed against the inner wall of the bridge crack 1, thereby achieving the purpose of strengthening the inside of the bridge crack 1. Solidify, filler is poured into the interior of the bridge crack 1 through the pouring hole 202, and after the filler solidifies, the entire reinforcement mechanism 5 can also provide additional connection anchor points. After the filler solidifies, its top is protected by the cover plate 2, thereby increasing the service life of the filler and sealing the filler inside the bridge crack 1. Then, the reinforcement plate 4 is installed on the top of the cover plate 2 through the embedded groove 401, and then fixed by the mounting bolts 402. The outside of the bridge crack 1 is further reinforced by multiple groups of reinforcement plates 4. The entire operation process is simple and convenient. The utility model can reinforce the inside of the bridge crack 1 through design, and at the same time improve the tightness between the filler and the bridge crack 1, thereby reducing the risk of crack expansion.
