全轻集料预制钢筋混凝土楼梯结构性能检验

Structural Performance Inspection of Precast Reinforced Concrete Stair with Lightweight Aggregate

摘要: 预制钢筋混凝土楼梯是目前装配式建筑中采用最为广泛的一类预制构件，但由于其自重较大而带来了一些使用上的困难。本文从减轻结构自重角度出发，提出一种基于页岩陶粒混凝土的全轻集料预制混凝土楼梯，并针对该新型预制楼梯足尺试件开展了结构性能试验研究。研究结果表明：新型预制装配式楼梯在有效减轻结构自重的同时，各项结构性能均能满足现行规范规定要求。研究结果对该新型装配式楼梯的工程应用提供了试验依据。

Abstract: The precast reinforced concrete staircase is a kind of most widely used precast component in the prefabricated buildings at present, but due to its large weight, it brings some difficulties in application. From the perspective of reducing weight, a new type of prefabricated concrete staircase based on shale ceramsite concrete is proposed in this paper, and the structural performance test of the staircase was carried out. The results show that the new type of prefabricated staircase can effectively reduce the weight of the structure, and all the structural properties can meet the requirements of the current code. The research results provide experimental basis for the engineering application of the new fabricated staircase.
