                                  [摘要]介紹了冬奧會標志性新建場館國家速滑館柔性索網結構下方除濕風管安裝技術。該風管布置在目前世界最大跨度(198m×124m)最大單層雙向正交馬鞍形索網結構上,索網為不穩定承重結構,對風管的柔性連接、安裝和固定帶來挑戰。通過嚴格控制支吊架選型、創新風管根部固定做法、自行研制風管吊裝機具,合理設置風管荷載以及綜合采用彈簧減振器、軟接短管等措施,解決了無參考先例大跨度索網結構下方安裝除濕風管的難題。

                                  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.
