Assembly type bridge butt joint expansion joint structure and anti-blocking drainage mechanism thereof

Abstract

The invention discloses an assembly type bridge butt joint expansion joint structure and an anti-blocking drainage mechanism thereof. The assembly type bridge butt joint expansion joint structure comprises bridge bodies installed on bridge piers, and base plates are arranged on the edges of the tail ends of the adjacent bridge bodies. The assembly type bridge butt joint expansion joint structure further comprises connecting blocks, a base body and side plates; the connecting blocks are installed at the edge of the top of a beam body in an embedded mode, sliding blocks are fixedly connected to the inner side walls of the bottoms of the base plates, clamping sliding connection is formed between the sliding blocks and the connecting blocks, and the sliding connection positions of the connecting blocks and the sliding blocks are arranged to be of a strip-shaped inner groove-shaped structure; the base body is fixed to the outer walls of the base plates, and a rubber strip is fixed to the outer edge of the base body in an embedded mode; and the side plates are positioned at the bottom of the edge of the beam body through bolts. According to the assembly type bridge butt joint expansion joint structure and the anti-blocking drainage mechanism thereof, the installation stability of an expansion joint is improved, multi-directional impact loads are weakened, rainwater can be effectively contained, the impact loads are utilized, and a drainage mechanism is prevented from being blocked by broken stone dregs.

Description

technical field [0001] The invention relates to the related technical field of assembled bridges, in particular to an assembled bridge butt joint expansion joint structure and an anti-blocking drainage mechanism thereof. Background technique [0002] During the assembly and construction of the bridge, due to the influence of the overall weight of the bridge and the compactness of the soil, it is necessary to reserve an expansion joint structure at the docking position of the bridge, so that the overall bridge will be affected by external factors such as thermal expansion and contraction. , The bridge as a whole will not experience severe impact dislocation, reducing bridge cracks, damage and other problems caused by such factors. [0003] However, the existing expansion joint structure has the following problems in use: [0004] 1. The use function is single. When the bridge is used for a long time and the vehicle passes by, the shielding object at the position of the expan...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a prefabricated bridge butt joint expansion joint structure and its anti-blocking drainage mechanism, in order to solve the above-mentioned background technology, the existing bridge expansion joint structure has a single function, and the unloading effect of the impact load of external vehicles is not good. , and due to the existence of gravel and dregs on the bridge road surface, its drainage structure is prone to accumulation caused by gravel and dregs, and it is impossible to efficiently clean the remaining gravel and dregs
