A road bridge crack reinforcement device

Abstract

The present invention discloses a reinforcement device for cracks of roads and bridges. The device comprises a set of internal connecting strips. A set of slide rails are arranged on the tops of the internal connecting strips, a set of chutes are formed in the bottom of a top cover plate, a set of connecting strip positioning bolts penetrate into the internal connecting strips, a set of teeth are arranged at the bottoms of the internal connecting strips, the two internal connecting strips are connected by a set of tension springs, penetration rod bases are also arranged at the bottoms of the internal connecting strips, and matched with reinforcement cage penetration rods, reinforcement cages penetrate into the middles of the reinforcement cage penetration rods, a set of cover plate positioning bolts penetrate into the periphery of the top cover plate, and a ring edge of an integrated structure is also arranged at the periphery of the lower surface of the top cover plate. The reinforcement device for cracks of roads and bridges can perform crack reinforcement well, and repair cracks, the usability of pavements is guaranteed on the premise of not re-laying the pavements, the evolution of damage to cracks is prevented, the production cost is low, and the reinforcement effect is good.

Description

technical field [0001] The invention relates to the field of crack reinforcement devices, in particular to a road bridge crack reinforcement device. 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 likely to be eroded by rain. 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. Need a kind of crack strengthening device to avoid the continuous expansion of the crack of road or bridge and influence the use of road and bridge now. Contents of the invention [0003] The purpose of the present invention is to provide a road bridge crack reinforcement device to solve the problems raised in the above background tec...
