摘要
深圳证券交易所营运中心工程采用型钢混凝土结构,其裙楼部分为巨型悬挑钢桁架结构,工程体量大,施工难点多。为解决悬挑平台的施工难题,使用了两台M1280D塔式起重机进行钢结构吊装。详细介绍了裙楼的预变形分析,裙楼钢结构的安装,巨型节点的拼装技术,超厚钢板的焊接技术及砂箱卸载技术等多项关键技术,创下了诸多工程亮点,保证了钢结构工程施工进度和工程质量。
Shenzhen Stock Exchange Operating Center project is steel-reinforced concrete structure,and its podium in particular is composed of giant cantilever truss,which has large engineering dimension and many construction difficulties.In order to solve construction difficulties of cantilever truss,two M1280D tower cranes are used to lifting steel structure.Some key technologies are introduced,including deformation analysis of podium,steel installation of podium,assembly technology of giant joint,welding technology of ultra-thick steel plate,and unloading technology by sand box,which ensure the construction progress and the quality of the project.
