摘　　要：工程东南角、西北角分别采用悬挑钢桁架作为幕墙支撑体系,建筑外立面采用独特的双“V”造型。为凸出外立面造型,该工程在设计时在5层~25层、30层~屋面采用了单根弧形悬挑钢骨架+立柱+斜拉杆受力体系,悬挑钢梁长度约2 m~12 m,同时在建筑物中部26层~29层采用满层悬挑桁架体系。由于26层建筑高度达到116.200 m,在保证安全的前提下,该工程采用自制吊篮作为人员操作平台+高空吊装法解决了高空安装悬挑钢桁架的难题。The southeast and northwest corners of the project are respectively used as the cantilever steel truss curtain wall support system,the building facade using a unique double V shape,for the convex facade modeling,the project in the design of the 5~25 layer A single arc cantilever steel skeleton+column+diagonal tie rod stress system is adopted for the 30th floor to the roof.The length of the cantilever steel beam is about 2m~12m.Meanwhile,the full-story cantilever truss system is adopted for the 26th to 29th floors in the middle of the building As the height of the 26-story building reaches 116.200,on the premise of ensuring safety,the project adopts self-made hanging basket as the personnel operation platform+overhead hoisting method,which well solves the problem of overhead installation of cantilevered steel truss.
