Abstract

The invention relates to an equidistant displacing type bridge expansion joint device. The device comprises a supporting system and profile steels; the supporting system and the profile steels are vertically connected; the supporting system comprises a supporting beam, a connecting frame, a compressing supporting seat and a bearing supporting seat; the bearing supporting seat and the compressing supporting seat are respectively mounted below and above the supporting beam through a U-shaped structure, and sliding plates which can slide and move are arranged on the contacting surfaces of the bearing supporting seat and the compressing supporting seat; the compressing supporting seat, the bearing supporting seat and the connecting frame are all connected through hinge pins. The device comprises a joint width adjusting system; each sliding plate is manufactured from stainless steel which is coated with a zirconium oxide coating by the cold spraying technology. Compared with the prior art, the equidistant displacing type bridge expansion joint device has the advantages that the supporting system and the joint width adjusting system are independent from each other, thus the modular processing of a modular expansion joint can be realized, the difficulty at manufacturing of the modular expansion joint is reduced, and joints between the profile steels can be automatically uniformly adjusted.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering, and in particular relates to an equidistant displacement bridge expansion joint device. Background technique [0002] During bridge design, the bridge deck will expand or shrink due to temperature changes and other reasons. Therefore, an expansion joint should be set between every two adjacent bridge decks with predetermined beam lengths. The expansion and contraction deformation of the bridge in the length direction can be mainly determined by bridge expansion joints. [0003] At present, there are many types of bridge expansion joint devices. The most common modular expansion joint is to set two "F"-shaped and "E"-shaped section steels symmetrically on both sides, and set different numbers of "king"-shaped section steels in the middle. , and then set a V-shaped rubber waterstop between the two steel sections to prevent rainwater from flowing into the substructure of the bridge from ...
