摘    要:模板高支撑架与传统支撑体系不同,高支撑体系具有跨度大、荷载重、高度高的特点,因此,对模板的支顶设计与施工提出了更高的要求。在确定安全设计与施工专项方案时,首先应结合可组织的材料进行支架形式选型支撑架的设计除满足计算中的相关依据外,须重视其相关构造要求;其次,还应加强施工过程的管理,严把进场材料关,严格支撑架的检查验收,精心设计混凝土浇筑方案,以确保高支撑架体的整体稳定和安全。平顶山市行政服务综合楼预应力框架梁具有高、大、重的特点。以《建筑施工扣件式钢管脚手架安全技术规范》为依据,介绍了高大模架采用满堂扣件式钢管支撑架的设计与计算、施工方法、安全措施和应用效果,实践表明是可行的。

关 键 词:模板工程  高大模架  设计  施工

Abstract:High formwork support is generally defined as the forwork support whose height is more than 8m,or whose length is more than 18m,or whose total construction load is more than 15km/m2,or whose line load is more than 20km/m2.Compared with the traditional supporting system,its features are as follows:large span,heavy load and great height,so higher demand to its design and construction is put forward.In the course of confirming special scheme,the first is the selection of support forms based on available materi...
Keywords:formwork engineering  high and large scaffold formwork  design  construction
