论复杂金属屋面虹吸雨排水重难点施工技术

Construction technology of siphon drainage of complex metal roof

滁州奥体中心游泳馆采用双曲连廊和椭球屋面,通过花瓣幕墙钢结构与大跨度钢网架屋盖结合为一体,其虹吸雨排水系统施工困难。通过深化屋面汇水分区划分,优化管道路径和立管位置,选择自动调整角度抱箍等措施,结合BIM技术,解决了虹吸雨排水施工难题,加快了施工进度,提高了施工质量。

The natatorium of Chuzhou Olympic Sports Center which adopts the hyperbolic veranda and the ellipsoidal roof integrates the steel structure of Petal Curtain Wall with the large-span steel grid roof, and it’s construction is difficulty in siphon drainage system. By deepening the division of roof catchment area, optimizing the pipeline path and the position of standpipe, choosing the measure of auto-adjusting angle and hoop, combining with BIM Technology, the construction problem of siphon drainage is solved, and the construction progress is quickened and the construction quality is improved.
