Abstract
Description
Technical Field
[0001] This utility model belongs to the field of road and bridge maintenance technology, and specifically relates to a road and bridge crack reinforcement structure. Background Technology
[0002] Bridges and roads often experience erosion and overloading during use, which directly or indirectly manifest as cracks and collapses. Currently, the repair of road and bridge cracks generally involves filling the crack with high-strength bonding materials to bond the walls on both sides, allowing the bridge to continue to be used. However, this direct filling method can only handle small cracks. When repairing wider cracks, the unevenness at the top of the repair site due to thermal expansion and contraction after filling, coupled with the fact that larger cracks can pull on the filling material and cause it to crack again, results in poor repair effectiveness. Utility Model Content

First protrusions 11 are fixedly connected to both ends of the bottom of the connecting frame 1, and second protrusions 12 are fixedly connected to the center of the bottom of the connecting frame 1. A connecting part 13 is arranged on one side of the first protrusion 11, and a positioning rod 3 is installed on the connecting part 13. Several first reinforcing ribs 4 and second reinforcing ribs 5 are connected between the connecting frame 1 and the support rod 2. Several second connecting grooves 41 are fixedly connected to the bottom of the first reinforcing ribs 4, and the first reinforcing ribs 4 and second reinforcing ribs 5 are detachably connected.
[0020] In this embodiment: the present invention consists of several connecting frames 1, with support rods 2 installed below each connecting frame 1. The connecting frames 1 are connected by the support rods 2, and each connecting frame 1 is detachably connected to the support rods 2. The position of the connecting frames 1 can be adjusted according to the location of the crack. The road surface on both sides of the crack is connected. First protrusions 11 are fixedly connected to both ends of the bottom of each connecting frame 1, and a second protrusion 12 is fixedly connected to the center of the bottom of each connecting frame 1. A connecting part 13 is provided on one side of the first protrusion 11. The support rod 2 and the first reinforcing rib 4 are connected by the first protrusion 11, the second protrusion 12, and the connecting part 13. A positioning rod 3 is installed on the connecting part 13. Position rod 3 allows it to be inserted into the road base layer to connect the new structure to the road surface. Several first reinforcing ribs 4 and second reinforcing ribs 5 are connected between the connecting frame 1 and the support rod 2. By setting the first reinforcing ribs 4 and second reinforcing ribs 5, the connection between the crack and the road surface on both sides is strengthened. Several second connecting grooves 41 are fixedly connected to the bottom of the first reinforcing rib 4, and the first reinforcing ribs 4 and second reinforcing ribs 5 are detachably connected. Several first reinforcing ribs 4 and second reinforcing ribs 5, together with the connecting frame 1 and the support rod 2, form a grid structure. When reinforcing and repairing cracks with a large width, the new structure is first assembled, with the first reinforcing rib 4 passing through the second connecting groove 41 on one side of the first protrusion 11, and then the support rod 2... The support rod 2 is placed inside the crack. The position of the connecting frame 1 is adjusted so that several connecting frames 1 are evenly spaced. Then, the connecting frame 1 is fixed with the mounting bracket. The positioning rod 3 is passed through the connecting part 13. By hammering and tapping, one end of the positioning rod 3 is inserted into the ground on both sides of the crack. Then, the position of the positioning rod 3 is fixed with the mounting bracket 32. Then, the second reinforcing rib 5 is installed so that the second reinforcing rib 5 passes through the connecting groove 52 on one side of the first reinforcing rib 4. Then, the position of the second reinforcing rib 5 is adjusted so that both ends are inserted into the soil layer at the bottom of the road surface. The positions of the first reinforcing rib 4 and the second reinforcing rib 5 are limited by the connecting bracket. Finally, the crack is filled with road repair material. The material is attached to the connecting frame 1, support rod 2, first reinforcing rib 4, and second reinforcing rib 5, filling the grooves 51 on both sides of the second reinforcing rib 5. Then, the protruding material in the gap is smoothed and repaired to complete the repair of the large gap in the road surface. This allows the present invention to strengthen the connection between the road surface on both sides of the gap when repairing the wide gap in the road surface, and to connect the cracked road surface. The contact area between the repair material and the present invention and the road surface is increased, thereby increasing the fusion effect between the repair material and the road surface. After the repair, the crack is less likely to crack between the crack and the repair material. Through the filling of the present invention, the deformation of the material after thermal expansion and contraction is reduced, thereby making the road surface repair position smoother after the repair.
[0021] The first protrusion 11 has a second connecting groove 41 that matches the first reinforcing rib 4 on one side, and the second protrusion 12 has a first connecting groove 21 that matches the support rod 2 on one side.

[0022] A limiting block 31 is fixedly connected to one side of the positioning rod 3, and an installation part 32 for limiting the positioning rod 3 is detachably connected to one side of the connecting part 13; by setting the limiting block 31, one end of the positioning rod 3 is limited, and its sliding distance is limited when the positioning rod 3 is installed inside the mounting groove 33.
[0023] A mounting groove 33 is provided on one side of the connecting part 13. The height and width of the mounting groove 33 match the height and width of the positioning rod 3. The positioning rod 3 is installed by setting the mounting groove 33. The mounting groove 33 matches the positioning rod 3, so that it can slide in a straight line and is more stable when connected to the road surface.
[0024] The second reinforcing rib 5 has several grooves 51 on both sides, and the grooves 51 are equally spaced on both sides of the second reinforcing rib 5.

[0025] The first reinforcing rib 4 has several connecting grooves 52 on one side, and the second reinforcing rib 5 is installed and fixed to the first reinforcing rib 4 through the connecting grooves 52. The connecting grooves 52 on one side of the first reinforcing rib 4 facilitate the installation of the second reinforcing rib 5, making it easy to splice the second reinforcing rib 5 and the first reinforcing rib 4.
[0026] The top end of the positioning rod 3 is provided with a fixing groove 34 that matches the mounting part 32, and the width of the limiting block 31 is greater than the width of the positioning rod 3. By setting the fixing groove 34, the positioning rod 3 can be limited and fixed by the mounting part 32 passing through the connecting part 13.
