Assembled bridge expansion joint structure

The utility model belongs to the technical field of bridge expansion joints, and particularly relates to a split mounting type bridge expansion joint structure which comprises two sets of bridge bodies distributed in a bilateral symmetry mode, the tops of the surfaces of the opposite sides of the two sets of bridge bodies are each provided with a set of mounting grooves, and the inner walls of the two sets of mounting grooves are each fixedly provided with a set of strip-shaped steel plates; through the arrangement of the supporting assembly, the slidable reinforcing plate and the supporting vertical plate form a supporting structure, supporting is carried out between the two sets of strip-shaped steel plates, the impact force between automobile tires and gaps when the automobile tires pass through is reduced, the tires are effectively protected, meanwhile, the stress deformation degree of the expansion joint structure after long-time use is effectively reduced, and the service life of the expansion joint str
