杭州亚运会棒球主场大跨度屋面重力流钢柱雨水系统施工技术

Construction Technology of Long-span Roof Gravity Flow Steel Column Rainwater System for Baseball Stadium in Hangzhou Asian Games

大跨度异形屋面排水采用重力流钢柱雨水系统,高大空间系统施工困难。运用BIM技术对雨水末端及钢桁架内雨水悬吊管进行深化整合,确定雨水斗安装位置、分析雨水悬吊管安装路径、选择不锈钢软连接作为补偿措施。介绍了雨水系统在施工前准备及钢柱雨水立管技术要求特点,从而将雨水管线序列与钢构件、结构柱、装饰柱完美结合,体现了建筑的高科技与时尚。

Gravity flow steel column rainwater system is adopted for drainage of long-span irregular roof,and the construction of large space system is difficult.BIM technology is used to deepen the integration of rainwater end and rainwater suspension pipe in steel truss,determine the installation position of rainwater bucket,analyze the installation path of rainwater suspension pipe,and select stainless steel soft connection as compensation measure.This paper introduces the preparation of rainwater system before construction and the technical requirements and characteristics of steel column rainwater riser,so as to perfectly combine the rainwater pipeline sequence with steel components,structural columns and decorative columns,reflecting the high technology and fashion of architecture.
