However, because the heat insulation cotton is filled between the upper aluminum alloy plate and the lower aluminum alloy plate, and the upper aluminum alloy plate is arranged in a slope shape, when the expansion joint can drive the upper aluminum alloy plate and the lower aluminum alloy plate to shift due to cold and hot expansion, and drive the heat insulation cotton to shift, the fastening connection between the heat insulation cotton and the upper aluminum alloy plate and the lower aluminum alloy plate is damaged, gaps are generated, and when raining, rainwater can easily silt up to cause siphon leakage.
