花篮式悬挑外架综合应用施工技术

CONSTRUCTION TECHNOLOGY FOR COMPREHENSIVE APPLICATION OF FLOWER BASKET TYPE CANTILEVER

某市万达商业广场外立面设计为玻璃—铝板—石材幕墙体系,项目采用花篮式悬挑外架,施工过程需确定幕墙外立面结构凹凸造型及幕墙龙骨距离外墙间距,立杆距外墙间距,满足结构施工阶段防护要求,同时满足幕墙施工阶段人员操作与防护,进而确定型钢悬挑长度。达到型钢悬挑及立杆定位一次到位的目的。

The façade of Wanda Plaza in a city is a glass-aluminum panel-stone curtain wall structure,the flower basket type cantilever frame is applied.The construction process needs to be determined patterns of the facade and the spacing between the keel and exterior wall,the spacing between the exterior wall and poles is determined,to meet the requirements for protection at the stage of structural construction and those for operation and protection at the stage of curtain wall construction.In addition,the length of the steel cantilever is finalized.The construction technology has the comprehensive advantage that steel cantilevers at a time.
