according to the waterproof and leak-proof expansion joint for the roof, the fixed side plate of the aluminum alloy panel is fixed on the first parapet wall through the expansion pipe bolts, the inclined panel covers the gap between the two corresponding structural joint parapet walls, the eave side plate extends out and hangs outside the outer side wall of the second parapet wall, meanwhile, the isolation plate on the inner side of the aluminum alloy panel is placed on the upper surface of the second parapet wall, the compression spring props against the horizontal seat plate to enable the horizontal seat plate to abut against and be placed on the upper surface of the second parapet wall, and the tension spring tightens the vertical seat plate to enable the isolation plate to abut against and be lapped on the inner side surface of the eave side plate, so that the waterproof and leak-proof expansion joint for the roof is formed.
