超长超大基础梁钢筋升降安装与递推卸载施工技术

Installation and Unloading Construction Technology of Super Long and Large Beam Foundation Reinforcement

基于普陀山观音圣坛工程4道混凝土基础大梁钢筋施工实例,对比常规施工方案,采用创新的整体升降安装工艺,并介绍支撑体系的构造要求,对大梁钢筋整体升降安装工艺的选用进行了详细说明。应用BIM技术对支撑架体进行设计、建立有限元分析模拟、分段递推流水吊装工艺等措施,确保结构安全,降低施工难度,保证施工质量的同时加快了施工进度。

Based on reinforcement construction of four concrete foundation beams of Guanyin Altar project of Mount Putuo,compared with common construction scheme,the new integral lifting installation technique was applied.The support system structure was introduced,selection of integral lifting installation technique of beam reinforcement was introduced in detail.The authors used BIM technology for support frame design,made finite element analysis,applied sectional hoisting technology which can ensure structure safe and quality,reduce construction difficulty and improve speed.
