[摘要]介绍了冬奥会标志性新建场馆国家速滑馆柔性索网结构下方除湿风管安装技术。该风管布置在目前世界最大跨度(198m×124m)最大单层双向正交马鞍形索网结构上,索网为不稳定承重结构,对风管的柔性连接、安装和固定带来挑战。通过严格控制支吊架选型、创新风管根部固定做法、自行研制风管吊装机具,合理设置风管荷载以及综合采用弹簧减振器、软接短管等措施,解决了无参考先例大跨度索网结构下方安装除湿风管的难题。

Abstract: This paper introduces the installation technology of dehumidification duct under the flexible cable net structure of The National Speed Skating Oval, the landmark new stadium of the Winter Olympic Games. The duct is arranged on the largest single layer bidirectional orthogonal saddle shaped cable net structure with the largest span (198m×124m) in the world. The cable net is an unstable load bearing structure, which brings challenges to the flexible connection, installation and fixation of the duct. The unprecedented problem of installing dehumidification air duct on large span cable net structure is solved by strict selection of supports and hangers, innovation of fixing method of air duct root, self developed air duct lifting equipment, reasonable setting of air duct load and comprehensive use of spring damper and soft joint short pipe.
