Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of road and bridge repair, in particular to a road and bridge crack repair and reinforcement structure. Background Art
[0002] Roads and bridges are essential infrastructure for urban planning and construction, ensuring smooth traffic and pedestrian access, accelerating urban development. Over time, cracks can develop on roads and bridges, compromising driving safety. If left untreated, these cracks can gradually widen, impacting the overall structural strength of the bridge. Existing crack repair methods involve filling the cracks with fillers and then paving them with asphalt or concrete. While these methods can repair cracks, the lack of traction between the crack sides can easily lead to further cracking as the bridge vibrates. Utility Model Content
[0003] The purpose of the utility model is to solve the above problems existing in the prior art and to provide a road bridge crack repair and reinforcement structure.
[0004] To achieve the above purpose, the present invention adopts the following technical solutions:
[0005] A road bridge crack repair and reinforcement structure comprises a reinforcement unit, a filling unit and a release unit. The filling unit is fixed to the lower end of the reinforcement unit, and the release unit is screwed through the reinforcement unit and penetrates into the release unit.
[0006] The reinforcement unit includes: a fixing plate, an inclined hole and a fastening screw. The fixing plate is symmetrically provided with a plurality of the inclined holes, each of which has a fastening screw arranged inside. The top surface of the fixing plate is provided with a plurality of long grooves, and the two side surfaces of the fixing plate are inclined at 45°.
[0007] The filling unit includes: a filling box, a bottom plate and an expansion type sealant. The filling box is fixed to the lower end of the fixing plate. The bottom surface of the filling box is provided with a bottom plate. The filling box is filled with expansion type sealant.
[0008] The base plate is made of polyethylene.
[0009] The release unit includes: a linkage rod, a puncture disk, a puncture column, a rectangular guide column and a screw rod. The puncture disk is fixed to the lower end of the linkage rod, and multiple puncture columns are fixed to the lower end of the puncture disk. A conical groove is provided in the middle of each puncture column. The lower end of the rectangular guide column is fixedly connected to the upper end of the bottom plate, and the upper end of the rectangular guide column slides through the puncture disk and penetrates into the linkage rod. The linkage rod is a hollow rod. The lower end of the screw rod is screwed through the fixed plate and is rotatably connected to the top surface of the linkage rod.
[0010] Compared with the prior art, the beneficial effects of the present invention are:
[0011] The utility model provides a road bridge crack repair and reinforcement structure, which can solve the problems raised in the background technology: cracks will appear in roads and bridges over time, and the cracks are likely to affect driving safety. If the cracks are not treated, they will gradually increase, thereby affecting the overall structural strength of the road bridge. The existing crack repair method is to fill the cracks with fillers and then pave asphalt or concrete in the cracks. Although the above method can repair the cracks, there is no traction between the sides of the cracks, and the vibration of the road bridge can easily cause the repaired cracks to continue to crack.

[0016] The technical solutions of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of 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.
[0017] A road bridge crack repair reinforcement structure includes: a reinforcement unit 1, a filling unit 2 and a release unit 3. The filling unit 2 is fixed to the lower end of the reinforcement unit 1, and the release unit 3 is screwed through the reinforcement unit 1 and inserted into the release unit 3.
[0018] The reinforcement unit 1 includes: a fixing plate 1-1, an inclined hole 1-2 and a fastening screw 1-3. The fixing plate 1-1 is symmetrically provided with a plurality of the inclined holes 1-2, and a fastening screw 1-3 is provided inside each of the inclined holes 1-2. The top surface of the fixing plate 1-1 is provided with a plurality of long grooves, and the two side surfaces of the fixing plate 1-1 are inclined at 45°.
[0019] The filling unit 2 includes: a filling box 2-1, a bottom plate 2-2 and an expansion type sealant 2-3. The filling box 2-1 is fixed at the lower end of the fixed plate 1-1, the bottom surface of the filling box 2-1 is provided with a bottom plate 2-2, and the filling box 2-1 is filled with expansion type sealant 2-3.
[0020] The material of the bottom plate 2-2 is polyethylene.
[0021] The release unit 3 includes: a linkage rod 3-1, a puncture disk 3-2, a puncture column 3-3, a rectangular guide column 3-5 and a screw rod 3-6. The puncture disk 3-2 is fixed to the lower end of the linkage rod 3-1, and multiple puncture columns 3-3 are fixed to the lower end of the puncture disk 3-2. A conical groove 3-4 is provided in the middle of each puncture column 3-3. The lower end of the rectangular guide column 3-5 is fixedly connected to the upper end of the bottom plate 2-2. The upper end of the rectangular guide column 3-5 slides through the puncture disk 3-2 and penetrates into the linkage rod 3-1. The linkage rod 3-1 is a hollow rod. The lower end of the screw rod 3-6 is screwed through the fixed plate 1-1 and is rotatably connected to the top surface of the linkage rod 3-1.
[0022] The working principle of this utility model is:
[0023] Before using this device, clean up the debris in the crack to ensure that there are no particles in the crack. Then use a grinder to trim the crack into a 45° groove to increase the contact area, and process the crack depth so that the crack depth matches the total height of the fixed plate 1-1 and the filling box 2-1. Then place this device in the crack. At this time, the two side surfaces of the fixed plate 1-1 are tilted to fit the crack groove. At the same time, the top surface of the fixed plate 1-1 is lower than the road surface height. Screw multiple fastening screws 1-3 into the two side surfaces of the crack groove respectively to apply traction to the crack to prevent the crack from being cracked due to vibration after filling. Then turn the screw 3-6 to move downward, driving the linkage rod 3-1 and the puncture disk 3-2 to slide downward along the rectangular guide column 3-5. The rectangular guide column 3-5 has a role in limiting the rotation of the puncture disk 3-2. The puncture disk 3-2 Move downward, driving the puncture column 3-3 to move and puncture the bottom plate 2-2. At this time, the expanding sealant 2-3 in the filling box 2-1 flows out through the tapered groove 3-4, expanding and filling the crack, which has the effect of filling and reinforcing the crack. Continue to rotate the screw 3-6 until the puncture column 3-3 penetrates into the bottom surface of the crack, further applying traction to the device to increase stability. The fixing plate 1-1 is provided with a countersunk threaded hole, and the top surface of the screw 3-6 is set in the countersunk threaded hole. The device can be used continuously at intervals along the crack and can be reasonably set at intervals according to the shape of the crack. After the device is fixed, asphalt concrete can be laid on the cracked road surface. The multiple long grooves provided on the fixing plate 1-1 can increase the contact area with the asphalt concrete, so that the asphalt concrete can be better laid on the crack to avoid warping and stratification.
[0024] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
