Comb-type bridge expansion joint plate structure and cleaning device thereof

Abstract

The invention discloses a comb-type bridge expansion joint plate structure and a cleaning device thereof. The comb-type bridge expansion joint plate structure comprises a first beam body, a second beam body arranged on one side of the first beam body, a comb plate supporting plate and a first comb-type expansion joint plate, wherein preformed grooves are formed in the first beam body and the second beam body respectively; an expansion joint is arranged between the first beam body and the second beam body; the comb plate supporting plate is arranged in the preformed grooves; the comb plate supporting plate is fixedly connected with the first beam body and the second beam body through fixing rivets; the first comb-type expansion joint plate is arranged in the comb plate supporting plate; anda second comb-type expansion joint plate is arranged on one side of the first comb-type expansion joint plate. The comb-type bridge expansion joint plate structure achieves the anti-seismic bufferingfunction; the strength of the structure at the expansion joint is improved; accumulated water and dust in the expansion joint are convenient to clean away; the internal structures of the expansion joint are prevented from being affected by the accumulated water; and the problem is solved that the first beam body and the second beam body squeeze each other to cause potential safety risks.

Description

technical field [0001] The invention relates to the technical field of comb-tooth bridge expansion joints, in particular to a comb-tooth bridge expansion joint plate structure and a cleaning device thereof. Background technique [0002] The thermal expansion and contraction of the bridge due to the influence of temperature will have a serious impact on the structure of the bridge body. In order to eliminate this effect, expansion joints are usually set on the bridge, and the expansion joints will follow the bridge body It expands and contracts with heat and contracts with cold, thereby reducing the stress on the bridge. However, due to the existence of gaps, rainwater will pour into the interior of the bridge and cause damage to the bridge body. In order to prevent rainwater from pouring in, rubber waterstops are usually used for waterstopping of expansion joints in road and bridge construction, and steel plates are anchored on both sides of the expansion joints for protecti...

AI Technical Summary

Problems solved by technology

However, due to the existence of gaps, rainwater will pour into the interior of the bridge and cause damage to the bridge body. In order to prevent rainwater from pouring in, rubber waterstops are usually used for waterstopping of expansion joints in road and bridge construction, and steel plates are anchored on both sides of the expansion joints for protection. , the steel plate is fixedly connected to the two beams. During the deformation process of the beam, the steel plate will be squeezed and deformed. Cause damage and affect the driving comfort of vehicles. With the change of the outdoor environment in our country, the service life of the bridge increases, the rubber is seriously aged and damaged, and it is difficult to replace, resulting in serious leakage at the bridge expansion joints, and the appearance and structure of the bridge are damaged by rain erosion.

The replacement of rubber waterstop is heavy workload, difficult to dispose of, long construction period, and has a great impact on traffic

[0003] The existing comb-shaped bridge expansion joint plates are easily damaged by bridge vibration, and the internal dust and accumulated water are not easy to clean, which affects the service life of the expansion joints
