摘　　要：在超高层建筑设计中,建筑外立面造型越来越多样化、新颖化,高楼层外伸结构不断增多,这也给主体结构外伸部分施工带来了难度。针对超高层外伸结构类工程实例,悬挑式支撑架仍是施工中常用的支撑体系。目前,悬挑式支撑架结构形式常用的有钢丝绳斜拉式和型钢下撑式。结合某项目超高层外伸结构的实际情况,讨论如何解决外伸结构模板支设的难题,找到具备经济适用、安全、工艺简便等优点的施工方式。In the design of super high-rise buildings,in order to highlight the vitality of the building,the building facade is more and more diversified and innovative,and the extension structure of high floors is increasing,which also brings difficulty to the construction of the extension part of the main structure.For such engineering examples of super high-rise external extension structure,the cantilever support frame is still a commonly used support system in construction.At present,the cantilever support frame structure is commonly used wire rope cable and steel support type.Combined with the actual situation of super high-rise extension structure of a project,this paper mainly discusses how to solve the problem of extension structure formwork support,and has the construction method with the advantages of economic application,safety and simple technology.
