摘要
高层建筑梁式转换层施工中,涉及大跨度大体积混凝土施工,施工方案直接影响到施工阶段的结构安全、施工质量和施工成本。结合工程实例,主要介绍高层建筑梁式转换层的施工重点及难点,采用叠合梁原理将结构分两次浇筑成型的施工方案、模板支撑体系的设计、钢筋连接绑扎、混凝土施工质量控制技术。
Beam conversion layer in high-rise building construction involves a large span of mass concrete construction. And the construction programs directly affect the structural safety of the construction phase, quality and costs. Combined with engineering examples, this paper introduces focus and the difficulties of construction conversion layer beam for high-rise building, the use of composite beam structure in two principles to pouring molding construction program, formwork support system design, steel bars banding and concrete construction quality control techniques.
