摘要
上海浦东城市规划和公共艺术中心新建工程中的旋转钢楼梯主要由箱形钢构件组成,底座采用弧形钢梁,以50 mm厚弧形钢腹板支撑起整个钢梯。为满足旋转钢楼梯安装的设计及验收规范要求,在受力梁底设置检测仪,通过加工厂预拼装完成后分7段进行吊装焊接,确保了旋转钢楼梯的牢固性与精准度。
The revolving steel staircase in the new project of Shanghai Pudong Urban Planning and Public Art Center is mainly composed of box steel members.The base adopts arc steel beam and the whole steel ladder is supported by 50 mm thick arc steel web.In order to meet the requirements of the design and acceptance specifications for the installation of revolvting steel staircase,a detector is set at the bottom of the stressed beam.After pre-assembly in the fabrication factory,it is hoisted and welded in 7 segments to ensure the firmness and accuracy of the revolving steel stairs.
