摘要
针对大跨度双曲面网架在允许范围内的同步可控卸载,通过对支撑以及卸载体系的仔细分析和研究,采取砂漏支撑卸载,保证了卸载过程的可控及同步。详细介绍了南宁吴圩国际机场新航站楼大跨度双曲面网架树形钢柱支撑卸载的方案选择及施工技术。
Based on synchronous and controllable unloading of large-span double-curved grid in allowable scope, by detail analysis and research on support and unloading system, the sand of times support unloading method is adopted to ensure the controllable and synchronous of unloading process. The authors introduced in detail the schemes selection and construction technology of tree-shape steel support of large- span double-curved grid in Nanning Wuxu International Airport terminal building.
