摘要
以前人对扣件式钢管脚手架及模板支架的研究为基础,通过现场调研并借助SAP2000有限元分析软件建立模型,分析高大模板支撑体系的纵距、横距、步距、扫地杆高度、竖直杆伸出顶端长度、水平加强层间距等构造因素在体系几何尺寸不变的情况下对其稳定承载力的影响机理。根据分析计算结果,提出高支模体系设计和施工中应注意的问题和建议。
On the base of the result that other people study the fastener-style steel pipe scaffold and supporting structure for formwork, the paper constructs the model by investigating the spot and making use of SAP2000 finite element analysis software, and analyses the mechanism deeply that how the constitution factors effect the stability bearing capacity when the physical dimension is unchanged. The constitution factors of the supporting structure for tall and large formwork include longitudinal distance, departure, step length, height of the floor members, length of uptight bars extruding from top and distance of bridging in horizontal planes. According to the analyzing of the calculating result, the paper puts forward some suggestion and problems about the supporting structure for tall and large formwork during the design and the construction, which the designers and the constructors can refer to.
