摘要
在上海虹桥商务区核心区(一期)06地块D19街坊工程中,由于结构形式的限制,致使大跨度钢桁架无法进行整体提升,只能采用设置临时支撑的方法进行分段吊装拼接。结合工程实际,通过合理设置临时支撑支承以支持构件的分段吊装,有效地克服了由于环境或场地条件限制的不利工况,顺利完成了大跨度钢结构的安装。
In Shanghai Hongqiao Business District Core Area(Phase I)06 Block D19 Neighborhood Project,the largespan steel truss can be not lifted integrally and only the method of setting up temporary support can be used for segmented lifting and splicing,due to the limitation of structural form.Combined with the actual project,the unfavorable working conditions due to the limitation of environment or site conditions are effectively overcome by reasonable setting up temporary support to conduct segmented lifting of components,and to complete the installation of large-span steel structure successfully.
