由于涉及造型及功能的需要，旋转楼梯的设计样式多种多样，给施工带来许多不便，如果支模方法不当，有时构件的误差不符合规范的规定，而且也不符合设计造型等的要求。结合阿尔及利亚某旋转楼梯工程，采用现浇式整体浇筑旋转楼梯及其固定轴，改变以往旋转楼梯先浇筑固定中轴柱，后将预制楼梯踏步固定在中轴柱的方法，既能保证旋转楼梯的整体性，又能使旋转楼梯的外观达到预制的效果，经济、美观，符合业主的要求。

The spiral staircase has many modes because of the need of shape and function, so it brings difficulties to construction. If the formwork is supported with improper method, the spiral staircase would not meet the requirements of codes and design. Based on some spiral staircase project in Algeria, the method pouring the integral spiral staircase and axis is adopted instead of traditional method that pouring the axis column firstly and then fixing the prefabricated staircase. The new method ensures the integrity of spiral staircase and the prefabrication appearance effect with good economic benefits.
