超宽变截面悬浇连续箱梁拆装式三角挂篮的设计与验算

Design and Checking of the Removable Triangle Hanging Basket for Cast-in-place Cantilever Continuous Box Girder with Super-width Variable Cross-section

拆装式三角挂篮是一种新型挂篮体系,具有受力合理、操作简单、运输方便和节省成本等优点。现结合芜湖市清水河公路桥工程实例,详细介绍超宽变截面悬浇连续箱梁拆装式三角挂篮的设计与验算,为类似工程施工提供参考作用。

As a new type of hanging basket system,the removable triangle hanging basket has advantages of reasonable force,simple operation,convenient transportation,saving cost and so on. Combined with the case of Qingshui River Highway Bridge in Wuhu,this paper introduces the design and checking of removable triangle hanging basket for cast-in-place cantilever continuous box girder with super-width variable cross-section,which can provide references for the similar engineering construction.
