超高层建筑装配式悬挑防护棚的设计与应用

Design and application of prefabricated cantilevered protective shed in super high-rise buildings

传统高空悬挑防护棚施工多采用悬挑型钢外加铺设临边防护,高空散拼作业较多,安全隐患大且高空作业人员施工效率低下,不能有效保证其成品施工质量。结合绿地汉口一号项目的实际情况,研发出一种能够快速安装的超高层建筑装配式悬挑防护棚工艺,并详细阐述其设计方法、施工过程。在汉口一号项目实际运用的同时取得了显著的经济效益,填补了装配式悬挑防护棚工艺的空白,并对其余类似项目提供了参考经验。

The construction of traditional high altitude overhanging protection shed mostly to adopt overhanging steel and laying edge protection,more high altitude scattered work,large safety risks and high altitude construction personnel construction efficiency,can not effectively ensure the construction quality of its finished products.Combined on the actual situation of Greenland Hankou No.1 project,this paper develops a super-high-rise building that can be quickly installed,and expounds the design method and construction processes in detail.With the actual application of Hankou No.1 project,remarkable economic benefit has been achieved,filling the gap between prefabricated cantilever protective shed technology,and providing reference experience in other similar projects.
