The invention relates to roof panels and provides a roof panel gutter shrinkage opening waterproof structure. The waterproof structure comprises a roof panel, a gutter flange, a drip plate and an elastic plate, and a connection seam is reserved between the roof panel and the gutter flange. The drip plate comprises a vertically downward extending portion and a connection portion extending along the roof panel, the extending portion is positioned outside the gutter flange, the connection portion extends into the connection seam and is fixedly connected with the lower surface of the roof panel, the elastic plate is clamped between the gutter flange and the extending portion and fixed to the gutter flange, and the drip plate and the extending portion are matched to seal the connection seam. The invention further provides a roof panel system comprising the waterproof structure. Since the connection seam between the roof panel and the gutter flange is sealed by the drip plate and the elastic plate to form a favorable hermetical environment, waterproof performance is guaranteed. In addition, due to high elasticity of the elastic plate, the elastic plate is capable of automatically adapting to deformation of the connection seam of the gutter and the drip plate to prevent air movement, and accordingly wind resistance is realized.
Description
technical field [0001] The invention relates to a roof panel, in particular to a roof panel gutter closure waterproof structure and a roof panel system. Background technique [0002] Due to its light weight, high strength, beautiful appearance, and convenient construction, the profiled metal roof system is widely used in large-scale projects such as airports, stadiums, exhibition centers, industrial plants, warehouses, railway station canopies, and railway station roofs. However, due to insufficient wind-resistance ability, the phenomenon of metal roof being torn off by wind frequently occurs, and the phenomenon of metal roof water seepage also frequently occurs. [0003] At the edge of the eaves and gutters of the metal roof system, a long metal drip sheet is usually installed between the gutter and the roof panel (in the length direction), and the drip sheet and the gutter are connected by rivets. Due to the gap between the rivet connection points, in windy weather, there...
