DESIGN AND CONSTRUCTION TECHNOLOGY OF SUPER HIGH STEEL STRUCTURE OF HUGE FRAME SYSTEM

Beijing Television Center is a project in which huge steel frame system has been firstly studied and applied.According to its design and construction features and difficulties,studies mainly focus on the precision controlling technique of vertical transfer of the frame plane controlling network,coordinate load construction technology of upper and lower gigantic steel trusses of the frame structure,installation of large-spanned 3-dimensional steel pipe truss,the safety protection of heavy hydraulic climbing frame,and the precise integral lifting of huge truss,as well as the operation of internal climbing tower crane group.It is presently the highest steel structure building in Beijing.
