摘要
结合高层住宅结构特点,设计了一种新型门架模板支撑体系,该新型门架为整体焊接结构,承载力高,在满足模板支设承载力要求的前提下,取消了扫地杆和水平加固杆的设置,节约成本,缩短工期。对该门架模板支撑体系进行了承载力试验和有限元模拟分析。根据试验和模拟分析结果,结合现行门架计算公式,推导提出了新型门架MF1225简化计算公式,为推广该新型门架模板支撑体系提供了理论支撑。
Considering the characteristics of high-rise residential structure,a new gantry formwork support system was proposed,in which the bottom reinforcing tube and ledger were abolished.This gantry is the whole welding structure and has high bearing capacity.Its bearing capacity tests and finite element analysis was carried out.According to the results of tests and finite element analysis and the current calculation formula,this study put forward a new simple formula for MF1225.It provides theoretical support for the promotion of the new gantry formwork support system.
