Technical Field
The invention relates to the field of bridge expansion joints, in particular to a spring support type bridge expansion joint structure.
Background
Bridge expansion joints: it is referred to that in order to meet the requirement of deck deformation, expansion joints are usually provided between two beam ends, between a beam end and an abutment, or at the hinge joint of a bridge. The expansion joint is required to freely expand and contract in two directions parallel to and perpendicular to the axis of the bridge, the expansion joint is firm and reliable, when a vehicle runs, the vehicle is smooth and free of sudden jump and noise, and the handrail and the bridge deck pavement are disconnected at the position where the expansion joint is arranged.
The function of bridge expansion joint: consists in adjusting the displacements and couplings between the superstructure caused by the vehicle loads and the bridge construction materials. Once the telescopic device of the skew bridge is damaged, the speed, the comfort and the safety of the vehicle are seriously influenced, and even the vehicle safety accident is caused.
Present bridge expansion joint is most for broach board type expansion joint device, and the apron that flushes with the road surface is left and right alternately the broach apron of putting, all leaves flexible volume according to the regulation between the top of every broach of apron and the tooth bottom of another apron, rolls for a long time along with the car, can lead to broach apron tooth tip to take place to warp, and the car noise is great when passing through.
