Abstract
The utility model relates to a railway bridge beam-end buffer backing plate, which is arranged above an expansion joint at the abutted joint of beam-ends of a railway bridge and covers the whole expansion joint. The buffer backing plate comprises two rubber plate layers and a steel plate layer, wherein the steel plate layer is compounded between the two rubber plate layers. The railway bridge beam-end buffer backing plate, which is arranged above the expansion joint at the abutted joint of beam-ends of a railway bridge and covers the whole expansion joint, utilizes deformation of the rubber plates to buffer vertical rotation angles of beam-ends and beam-end projections, has a buffering effect on rails above the expansion joint, and simultaneously utilizes the steel plate to ensure certain rigidity and prevents the rails above the expansion joint from deforming due to beam-end rotation angles, thereby guaranteeing stable running of trains.
Description
Technical field
The utility model relates to railroad bridge, is specifically related to the parts that railroad bridge beam-ends joint uses.
Background technology
Lay track on long-span bridge and simple bridge, bridge produces the beam-ends corner under the load action of train.Because beam-ends vertical corner and beam-ends hang the influence of length, may cause the track projection above the shrinkage joint, influence the smooth-ride of train.
The utility model content
Technical problem to be solved in the utility model is: a kind of railroad bridge beam-ends buffer plate is provided, this buffer plate is arranged on the top at railroad bridge beam-ends joint shrinkage joint, track to the top, shrinkage joint plays cushioning effect, guarantees that the track of top, shrinkage joint does not deform because of the beam-ends corner.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be:
Railroad bridge beam-ends buffer plate, it is arranged on the top at railroad bridge beam-ends joint shrinkage joint and covers whole shrinkage joint, and it comprises two-layer rubber tile and one deck steel plate, between the compound two-layer rubber tile of steel plate.
In the such scheme, the thickness of described steel plate is 0.5-2cm, and the thickness of rubber tile is 1.5-5cm.
The utility model railroad bridge beam-ends buffer plate is arranged on the top at railroad bridge beam-ends joint shrinkage joint and covers whole shrinkage joint; Buffer plate utilizes rubber tile to be out of shape to cushion the beam-ends vertical corner and beam-ends hangs; track to the top, shrinkage joint plays cushioning effect; utilize steel plate to guarantee that buffer plate has certain rigidity simultaneously; the track of guaranteeing the top, shrinkage joint is not because of the beam-ends corner deforms, thus the smooth-ride of assurance train.
