The invention relates to the technical field of prefabricated staircases, and discloses an assembly type prefabricated spiral staircase which comprises a plurality of hollow cylinders which are sleeved up and down, the upper portion of each hollow cylinder is provided with a sleeving part with a circular section, the outer side face of each hollow cylinder is fixedly connected with stair steps, and the top and the bottom of each hollow cylinder are provided with an upper gear ring and a lower gear ring respectively. Tooth grooves of the upper gear ring and the lower gear ring are formed in the radial direction, the number of teeth of the upper gear ring is equal to that of teeth of the lower gear ring, steel bar frameworks are arranged in the hollow cylinder, the sleeving part and the stair steps, the spiral stair is simple in structure, convenient to assemble and stable in structure, and the assembling efficiency is effectively improved.
本发明公开了一种装配式预制旋转楼梯，涉及预制式楼梯技术领域，包括多个上下套接的空心圆柱，空心圆柱的上部设有截面形状为圆形的套接部，空心圆柱的外侧面固定连接有楼梯踏步，空心圆柱的顶部与底部分别设有上齿圈与下齿圈，上齿圈与下齿圈的齿槽均沿径向开设，上齿圈与下齿圈的齿数相等，空心圆柱、套接部及楼梯踏步内均设有钢筋骨架，该种旋转楼梯结构简单，装配方便，且结构稳固，有效提高了装配效率。
