Description

Technical Field

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

[0002] After long-term use, existing roads and bridges will have cracks of varying sizes on their surfaces due to temperature changes, load-bearing and other reasons. In order to extend the service life of roads and bridges and reduce the occurrence of accidents, construction workers generally use reinforced structures to deal with the cracks on roads and bridges.

[0003] At present, most of the road and bridge crack reinforcement structures use fixing screws to fix the reinforcement structure on the surface of the road and bridge. There is a lack of fixing devices inside the cracks, which will lead to poor fixing effect of the reinforcement structure. After long-term use, the reinforcement structure is easy to fall off due to loose screws, which affects the crack treatment effect and reduces the service life of the road and bridge. Utility Model Content

[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0025] Embodiment 1, as Figure 1-Figure 5 As shown, the utility model provides a road bridge crack reinforcement structure, comprising a traction mechanism 1, and a fixing mechanism 2 is fixedly sleeved on the outer wall of the traction mechanism 1;

[0026] The traction mechanism 1 includes a bottom plate 101, two slide grooves 102 are provided on the top of the bottom plate 101, and sliders 103 are movably embedded in the inner walls of the two slide grooves 102. Two hinges 104 are fixedly installed on one side of the outer wall of the bottom plate 101, and a protective cover 105 is fixedly installed between the outer walls of the two hinges 104. A hole 106 is provided on the top of the bottom plate 101, and a threaded rod 107 is movably inserted into the inner wall of the hole 106. A drill bit 108 is rotatably connected to the outer wall of the threaded rod 107. A gear 109 is movably sleeved on the outer wall of the threaded rod 107, and the outer wall of the gear 109 meshes with the outer wall of the gear 109. Two racks 110 are connected together, and the bottoms of the two racks 110 are fixedly connected to the top of the slider 103, the outer wall of the threaded rod 107 is movably sleeved with a pawl self-locking device 111, and the top of the pawl self-locking device 111 is fixedly connected to the bottom of the gear 109, a group of springs 112 are fixedly installed on one side of the outer wall of the two racks 110, a fixing plate 113 is fixedly installed between the outer walls of the two groups of springs 112, a group of threaded holes 114 are opened on the tops of the two fixing plates 113, and a group of fixing screws 115 are rotatably connected to the inner walls of the two groups of threaded holes 114.

[0027] The effect achieved by the entire embodiment 1 is that the protective cover 105 can keep the surface of the reinforcement mechanism flat. After rotating the threaded rod 107, the drill bit 108 will be driven to drill downward into the crack to fix the position of the reinforcement mechanism. Then, two sets of fixing screws 115 are drilled into the ground to further fix the position of the mechanism. Then, the gear 109 is rotated, and the gear 109 will drive the two racks 110 to contract. At this time, the two sliders 103 at the bottom can prevent the racks 110 from moving in the wrong direction. Then, the two racks 110 will pull the two fixed plates 113 through two sets of springs 112 to provide a traction force to the cracks to prevent the cracks from expanding continuously over time.

[0028] Embodiment 2, as Figure 2-Figure 5 As shown, the fixing mechanism 2 includes two first bearings 201, the outer walls of the two first bearings 201 are fixedly installed with first fixers 202, the inner walls of the two first fixers 202 are movably inserted with first brackets 203, the outer walls of the two first brackets 203 are movably sleeved with second fixers 204, one side of the outer walls of the two second fixers 204 are fixedly installed with stabilizing plates 205, one side of the outer walls of the two stabilizing plates 205 are fixedly installed with third fixers 206, the inner walls of the two third fixers 206 are movably inserted with second brackets 207, the outer walls of the two second brackets 207 are movably sleeved with fourth fixers 208, the outer walls of the two fourth fixers 208 are fixedly installed with second bearings 209, the outer wall of the drill bit 108 is fixedly inserted inside the first bearings 201, and the outer wall of the drill bit 108 is movably inserted inside the second bearing 209.

[0029] The effect achieved by the entire embodiment 2 is that the second bearing 209 can slide on the outer wall of the drill bit 108. When the drill bit 108 descends and drills into the road, the second bearing 209 will always be in contact with the bottom of the crack, and together with the first bearing 201 that continues to descend from the top, the first bracket 203 and the second bracket 207 cooperate with each other, so that the stabilizing plate 205 and the inner wall of the crack fit each other, avoiding displacement of the reinforcement structure.

[0030] Working principle: When the reinforcement structure needs to be used, the bottom of the reinforcement structure can be placed inside the crack first, and then the worker opens the protective cover 105 and rotates the threaded rod 107, so that the drill bit 108 fixed by the rotation of the outer wall of the threaded rod 107 continues to descend and drills into the crack to fix the position of the reinforcement structure. When the drill bit 108 is in the process of descending, the second bearing 209 movably sleeved on its surface will continue to move, always in contact with the bottom of the crack, and together with the continuously descending first bearing 201, through the first fixer 202 and the fourth fixer 208, drive the first bracket 203 and the second bracket 207 to move together, so that the stabilizing plate 205 is attached to the inner wall of the crack to prevent the reinforcement structure from being displaced during use, and then rotate the fixing screw 115 to make it drill into the roads on both sides of the crack to fix the position of the reinforcement structure, and then rotate the gear 109. When the gear 109 rotates, it will drive the two racks 110 and the slider 103 to slide together, pull the two sets of springs 112 inward, and provide inward traction for the two fixing plates 113.

[0031] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
