摘　　要：高层建筑转换层是建筑结构中重要部位,其中转换层结构模板支撑系统直接关系到整个工程质量品质。通过探讨梁式转换层扣件式模板支架计算模型选取,对模板支架整体稳定承载力进行数值分析,阐述各杆件对支架内力分配的贡献及斜撑倾斜角度对整体稳定承载力的影响,提出预防和改进措施。对转换层高支模支架的设计和施工具有实际的指导意义,可为同类工程提供参考。Slab transform floor of the high-rise building is an important part of building,formwork supporting system is pivotal,because it has direct relation to the quality of engineering construction.By exploring the selection of model for R.C transfer floor fastener falsework,it is conducted a numerical analysis of stability capacity of falsework.The paper described the various bars on the falsework internal force distribution and the effect of bracing angle on the overall stability of the bearing capacity and preventive and improvement measures are also proposed.Which provides a pratical guide for design and construction of conversion layer on falsework,and a reference for similar projects.
