摘要
为解决部分钢连廊跨度大、自重大、施工复杂且常规设备无法完成整体吊装的问题,以扬州建工科技园A2-A3钢连廊项目为例,在钢连廊施工过程中,对超大型构件液压同步提升施工技术进行探究和分析;采用结构分析软件SAP2000对提升结构及提升支架进行建模分析,验算各构件在提升过程中的稳定性。这一提升技术不仅可解决大跨度钢连廊整体吊装问题,也可缩短钢连廊施工周期,降低成本,保证施工质量。
In order to solve the problems of large-pan,heavy self weight,complex construction,and the inability of conventional lifting equipment to complete the overall lifting of some steel corridors,taking the A2-A3 steel corridor project of Yangzhou Construction Engineering Science and Technology Park as an example,the hydraulic synchronous lifting construction technology of ultra large components during the construction process of the steel corridor is explored and analyzed.The structural analysis software SAP2000 is used to model and analyze the lifting structure and lifting bracket,and verify the stability of each component during the lifting process.This lifting technology can not only solve the overall lifting problem of large-span steel corridors,but also shorten the construction cycle of steel corridors,reduce costs,and ensure construction quality.
