Bridge expansion seam

The utility model relates to a constructive component, or rather a bridge expansion joint. The technical solution is that a portion of the axial cord that is equipped in the left and right side plates and connected to an anchoring reinforced bar is not perpendicular to the left and right side beams, with a certain degree of inclination. A portion of the tap holes is divided into two rows at least in the left side beam, as well as arranged at intervals up-and-down, opposite to the up-and-down position of the tap holes on the right side beam. A horizontal lug boss is arranged on the upper part of the left and right side beams, which is geared to the thickness of the rubber sealing belt. The utility model has the advantages in that the expansion joint is of good shock resistance and connected to the roadbed or the bridge foundation stably, with long service life.
