摘　　要：提出了一种基于超高层爬模体系优化设计的核心筒钢筋超层绑扎技术,通过增加爬模体系的顶层和次顶层操作平台,为钢筋工提供了在本层模板合模过程中的上一层墙柱钢筋绑扎的工作面,同时对爬模进行优化设计,实现了核心筒钢筋作业的不间断流水施工,避免了窝工的产生,提高了超高层建造的效率。通过有限元分析,对加高后的爬模在爬升、施工和停工3种工况下,在施工荷载、堆载、风荷载和自身重力作用下的内力进行了受力分析,并根据结果对架体进行了加强,这一系列措施保证了超层绑扎在提高效率的同时,结构安全可靠,可供核心筒具备先行条件的超高层项目进行借鉴和推广。A passing layer binding technology of core tube reinforcement based on the optimization design of super highrise climbing formwork system is proposed.By adding the top layer and sub top layer operation platforms of the climbing formwork system,the reinforcement workers are provided with a working face for binding the wall column reinforcement of the previous layer in the formwork closing process of this layer.At the same time,the climbing formwork is optimized to realize the continuous flow construction of core tube reinforcement work and avoid the idling of workers.The efficiency of super high-rise building is improved.Through the finite element software analysis,the internal forces of the elevated climbing formwork under the action of construction load,surcharge load,wind load and its own gravity under the three working conditions of climbing,construction and shutdown are analyzed,and the frame is strengthened according to the results.This series of measures ensure that the passing layer binding improves the efficiency and the structure is safe and reliable,which can be used for reference and promotion of super high-rise projects with advance conditions for the core tube.
