Abstract: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 stairease and axis is adopted instead of traditional method that pouring the axis column firstly and then fixing the prefabricated stairease.The new method ensures the integrity of spiral staircase and the prefabrication appearance effect with good economic benefits.
