摘要
以上海博物馆东馆内部螺旋钢坡道结构为例,重点对该结构的主体安装及斜拉索施工作了详细阐述。对由空间索面成对斜拉的螺旋坡道结构在实际施工过程中的节点优化、临时支撑系统设置、安装工艺以及拉索张拉等关键技术进行了总结,为类似结构施工提供了借鉴。
Taking the spiral steel ramp structure in the East Hall of Shanghai Museum as an example, the main body installation and stayed cable construction of the structure are described in detail. The key technologies such as node optimization, temporary support system setting, installation technology and cable tensioning of the spiral ramp structure with paired cable planes in the actual construction process are summarized, which provides a reference for the construction of similar structures.
