Bridge expansion joints Located at the movable end of the bridge superstructure and at the bridge deck fracture, it is mainly composed of a force transmission support system and a displacement control system. The main function of the special-shaped steel bridge expansion joint is to transfer the vertical and horizontal loads of vehicles to the bridge beam through the support structure. The second is to adapt to the changes in the longitudinal and transverse displacements of the bridge and the changes in the angle of the beam end warping to ensure that the displacement of the bridge superstructure can be realized under the effects of temperature changes, concrete shrinkage and creep, and loads. It does not generate additional internal force and can ensure smooth driving. It has the functions of expansion, load-bearing, waterproofing, and smoothness, making the bridge run smoothly and expand freely. Its quality directly affects the overall performance and life of the bridge. Depending on the displacement of the bridge, single-slit, double-slit or multi-slit special-shaped steel bridges can be used.
