浙江、福建等地广泛采用钢筋混凝土悬臂楼梯作为住宅楼梯的主要形式,深受设计人员、施工人员和广大住户的欢迎。悬臂楼梯踏步板,悬臂板为悬臂受力构件,上部受拉,主筋配置在上部。它与中间设墙的简支楼梯比较,梯间通视条件好,空间开阔,易于搬运大件家具。踏步板、悬臂板采用预制,节省了大量木材,便于工厂大规模生产。笔者在多年采用悬臂楼梯的实践中,进行了深入的调查研究,与设计、施工人员开展了技术探讨,对节
In Zhejiang and Fujian, reinforced concrete cantilevered stairs are widely used as the main form of residential staircases, and they are welcomed by designers, constructors, and residents. Cantilevered stair treads, cantilever plates are cantilevered members, the upper part is tensioned, and the main bar is arranged in the upper part. Compared with the simply-supported staircase with a wall in the middle, the condition of the ladder-passage is good, the space is open, and it is easy to carry large pieces of furniture. Stepping plates and cantilever plates are prefabricated, which saves a lot of wood and facilitates mass production at the factory. In the practice of using cantilevered stairs for many years, the author conducted in-depth investigation and research, and conducted technical discussions with design and construction personnel on the festival.
