Roof embedded integrated expansion joint structure

The invention discloses a roof pre-embedded integrated expansion joint structure which comprises two vertical side plates, two vertical side plates, two vertical side plates and two vertical side plates. The bottoms of the two vertical side plates extend back to back to form the pressure-bearing flanges; the middle parts of the two vertical side plates extend back to back to form the water stop flange, and a clamping gap is formed between the vertical side plates and the water stop flange; the rubber plate is movably and vertically arranged in the two telescopic gaps, the top of the rubber plate extends to form an upper flange, the bottom of the rubber plate extends to form a lower flange, the two opposite sides of the rubber plate respectively form pulling flanges, and the clamping gaps are clamped on the pulling flanges; a plurality of upper rib plates connected among the upper flange, the upper parts of the vertical side plates and the upper parts of the pulling flanges are formed at the upper part of the
