[0002] Road bridge expansion joints refer to expansion joints that are usually set between the two beam ends, between the beam ends and the abutments, or at the hinged position of the bridge to meet the requirements of bridge deck deformation. The expansion joints are required to be able to freely expand and contract in both directions parallel and perpendicular to the bridge axis, be firm and reliable, and be smooth without sudden jumps and noise when vehicles pass through; they must be able to prevent rainwater and garbage and soil from infiltrating and blocking; installation, inspection, maintenance, and removal of dirt must be simple and convenient. At the expansion joints, the railings and the bridge deck pavement must be disconnected. Generally, there are butt joints, steel support types, combined shear types (plate types), modular support types, and elastic devices.
