摘　　要：中央电视台电视文化中心工程从标高129.750m至137.720m设计为6榀高达8m的钢桁架,钢桁架跨度最大约40m,下方悬挂着两层(26D层和27层)钢结构,钢结构重量660t。桁架在5层平台上拼装成整体,利用液压提升器提升就位,再利用提升横梁将两层水平桁架提升就位,保证了质量和安全。CCTV Television Cultural Center project adopts six steel trusses as high as 8m with the maximum span about 40m at the elevation of 129.759m - 137.720m, and two storeys （26DF and 27F） of 660-ton steel structure are suspended below. These steel trusses are assembled into a whole on the fifth floor and are lifted by hydraulic lift to the right position, and then two-storey steel truss is lifted by lifting beam. In this way, relevant quality and safety can be guaranteed.
