摘　　要：延庆海坨塔采用高空竖向平面聚氟乙烯(Ethylene Tetra Fluoro Ethylene,以下简称ETFE)张拉膜施工技术,目前国内ETFE膜大范围应用于屋面结构,对于竖向结构,仅在高度较低的环境下采用ETFE膜片或采用充气膜形式进行装饰,不能完全发挥ETFE膜的各项优点。因此,此类安装方式可提高ETFE膜的适用范围,能得到推广性应用,带来显著的社会效益。通过介绍ETFE膜从深化设计、加工制作到膜材安装的施工工艺,旨在形成完善的施工工艺流程及施工保障措施,为类似工程提供借鉴经验。This article mainly introduces the construction technology of high altitude vertical plane ETFE tensile membrane for Yanqing Haituo Tower.Currently,domestic ETFE membranes are widely used in roof structures.For vertical structures,only using ETFE membranes or inflatable membranes for decoration in low altitude environments cannot fully exploit the advantages of ETFE membranes.Therefore,this installation method can improve the applicable range of ETFE films,can be widely applied,and bring significant social benefits.By introducing the construction process of ETFE membrane from detailed design,processing and fabrication to membrane installation,the aim is to form a complete construction process and construction assurance measures,providing reference experience for similar projects.
