Waterproof mounting structure for curved surface net rack roof skylight

The invention discloses a waterproof mounting structure for a curved surface net rack roof skylight. The waterproof mounting structure comprises a plurality of main purlins, a plurality of square stand columns, a skylight structural ring beam, an aluminum-magnesium-zinc roof colored sheet, a transverse n-shaped support and a longitudinal ne-shaped liner purlin. The multiple main purlins are perpendicularly crossed to define a netted first supporting surface. The periphery of the first supporting surface is connected with the periphery of a skylight hole of a curved surface net rack roof. Compared with traditional waterproof measures, the curved surface roof skylight structure is simple in structure, good in waterproof effect, low in construction cost and convenient to apply and popularize. 本申请公开了一种用于曲面网架屋面天窗的防水安装结构，包括：多根主檩条、多根方形立柱、天窗结构环梁、铝镁锌屋面彩板、横向几字形支架和纵向几字形衬檩条，多根主檩条相互垂直交叉围成网状的第一支撑面；第一支撑面的周缘与曲面网架屋面的天窗孔周缘相连接。该曲面屋顶天窗结构，与传统的防水措施相比较，构造简单，防水效果良好，施工成本低，便于推广应用。
