预制装配式混凝土楼梯设计与应用

Design and application of precast concrete staircases

从整体计算、工厂制作及施工便捷性对预制装配式混凝土楼梯(PC楼梯)的三种连接方式进行讨论,可知高端固定铰支座、低端滑动铰支座的连接方式具有优势,适宜推广。通过对PC楼梯三种受力工况进行分析,给出PC楼梯的设计思路、计算要点和构造要求,并在工程案例中进行了应用。

Three connection methods of precast concrete staircases( PC stairs) were discussed about integral calculation,factory production and construction convenience. High-end fixed hinge supports,low-end sliding hinge support connection mode has the advantage,and it is suitable for popularization. The analysis of the PC staircase under three stress conditions were done,the design idea of PC stairs,calculation points and construction requirements were given. The method is applied in the engineering case.
