劲性骨架在辰塔大桥主塔施工中的应用

Application of stiffness skeleton in construction of main tower of Chen-Ta bridge

斜拉桥主塔体中各类结构构件施工均需采用型钢组成的劲性骨架完成,以辰塔公路越黄浦江大桥新建工程主塔施工为例,详细介绍了劲性骨架的设计、制作、安装,论述劲性骨架在斜拉桥主塔施工中的作用,为今后类似工程主塔劲性骨架的施工提供借鉴。

All kinds of structural components in the main tower of cable-stayed bridge are required to be completed by the stiffness skeleton of the section steel. Taking the construction of the main tower of the new project of Chen-Ta highway which across the Huangpu River bridge as an example,introduced the construction function in diagonal cable bridge main tower of stiffness skeleton design,the manufacture,the installment in detail and the elaboration stiffness skeleton. It provides reference for the construction of the stiff skeleton of the main tower of similar engineering in future.
