Bridge durability dustproof sliding plate stretching device and construction method thereof

Abstract

The invention discloses a bridge durability dustproof sliding plate stretching device which comprises a stretching joint component and a stretching plate, wherein one end of the stretching plate is fixed on one side of the stretching joint component through an anchoring bolt, and the other end of the stretching plate is tightly attached to the other side of the stretching joint component and covers the stretching joint of the stretching joint component. The invention also discloses a bridge durability dustproof sliding plate stretching device and a construction method thereof. The bridge durability dustproof sliding plate stretching device has the advantages that when the beam body stretches and deforms, a comb-tooth-shaped steel plate slides along with the beam body, and the stretching plate slides along with the beam body, so that the self-stretching of the stretching plate is realized; the stretching joint is covered by the stretching plate, so that the dust-proof effect is achieved, a water stop belt can be prevented from aging in the expose to the sun, the service life of the stretching joint component is prolonged, and the top of the stretching plate is flush with the top ofconcrete pouring, so that the bridge deck is flat, and the traveling comfort is good; one end of the stretching plate is designed into a wedge-shaped structure, and sand particles cannot be accumulated at the stretching joint, so that the stretching joint can work normally for a long time.

Description

technical field [0001] The invention relates to the technical field of bridge expansion joints, in particular to a bridge durable dust-proof sliding plate expansion device and a construction method thereof. Background technique [0002] Since the expansion joints of the bridge directly bear the repeated loads of the wheels, the small unevenness of the bridge deck under the action of the vehicle load will cause it to be damaged by a large impact, and the expansion joints are exposed to the atmosphere for a long time, and the service environment is relatively harsh , is the most vulnerable and difficult to repair part of the bridge structure. [0003] Once the bridge expansion joints are damaged, not only will the passers-by feel uncomfortable and lack a sense of security, but the impact of the vehicle on the superstructure caused by the damage will not only deteriorate the driving conditions, but also affect the force of the main structure of the bridge. If the service life ...
