摘要
通过对现行立式钢油罐螺旋形盘梯的两种安装及预制方法的评价,推荐整体预制现场吊装法及按盘梯曲率半径组对的预制方法;并着重对盘梯曲率半径的计算方法及盘梯预制中的整形问题作了讨论。
Through the evaluation of the two prefabrication and construction methods presently used for vertical steel oil tank, this paper recommends the wholly prefabricating and field hoisting method with the round ladder assembled according to its radius curvature. It also emphasises the calculating method for the radius curvature of the round ladder and discusses the problem of rectifying the form of round ladder in prefabrication.
