天津高银117大厦水平结构施工节奏管理研究

Rhythm Management Research on the Horizontal Structure Construction of Tianjin Gaoyin 117 Building

天津高银117大厦采用"不等高同步攀升"工法进行施工,核心筒竖向结构采用低位顶升模架作为施工平台,超高层建筑水平结构的施工相比于竖向结构的施工组织更为复杂,由于低位顶升模架系统在设计之初对于水平结构的施工考虑不全面,导致水平结构施工滞后于竖向结构施工。天津高银117大厦水平结构施工节奏的形成,是通过在内筒设计机械提升装置、创新施工材料运输方式并经过系统地对整体施工工序的创新设计来实现的。而水平结构的施工与竖向主体结构的施工相互影响,并综合形成大厦主体结构施工的整体节奏。

Compared with the construction organization of the vertical structure,the horizontal structure is more complex in Tianjin Gaoyin 117 Building.The design of the jack-up formwork system is incomprehensive in construction of the horizontal structure,it leads to the progress of the horizontal structure which is seriously leg behind that of the vertical structure.The new construction rhythm formation of the horizontal structure is obtained by means of redesigning the mechanical lifting device in the core tube,modifying the transportation ways of the construction materials and systematically innovative design on the whole construction process.The construction between the vertical structure and horizontal structure influence each other,and composite the overall construction rhythm of the main structure of Tianjin Gaoyin 117 Building.
