The invention relates to a road and bridge crack reinforcing device. The device comprises a groove formed in a road surface and located above a crack, a steel plate arranged in the groove, a plurality of vent holes formed in the middle of the top face of the steel plate, a plurality of threaded through holes formed in the two sides of the top face of the steel plate, a plurality of fixing threaded holes formed in the bottom face of the groove and corresponding to the threaded through holes, fixing bolts which are screwed in the threaded through holes and the corresponding fixing threaded holes, pouring holes which are formed in the road surface, mortar can be conveniently poured into the cracks through the pouring holes, and the mortar is arranged in the cracks from bottom to top, so that air bags are prevented from being generated in the mortar, and the firmness of the mortar is not influenced; the steel plates can be fixed in the grooves through the fixing threaded holes, the threaded through holes and the fixing bolts, the steel plates can reinforce cracks and can also reinforce poured mortar, and the mortar can enter the grooves from the cracks through the vent holes.
Description
technical field [0001] The invention relates to a crack reinforcement device for road bridges. Background technique [0002] After long-term use, roads and bridges will be damaged due to the impact of hard objects, thermal expansion and contraction, etc., and cracks will occur. After cracks, the strength of the damaged part will decrease, the load-bearing capacity will be greatly reduced, and it will be more easily eroded by rainwater. If the cracks are not treated, the damage will continue to expand, eventually leading to the need for major repairs or even scrapping of roads or bridges. Therefore need a kind of crack reinforcing device to avoid the continuous expansion of the crack of road or bridge and influence the use of road bridge. [0003] At present, existing road and bridge crack reinforcement devices pour mortar into the cracks from top to bottom. In this way, the poured mortar is easy to loosen and separate from the cracks. The applicability is not strong, which ...
