摘要
抱箍法盖梁施工与满堂支架法、预留孔法等相比有施工操作简单、节省材料节省劳动力、周期短等明显的优势。抱箍法盖梁施工需要严密的计算,主要包括:侧模支撑计算、纵梁计算、抱箍计算。以郑州市K0+514主线上跨京广铁路分离式立交桥桥墩盖梁为例,验算盖梁施工中的抱箍应力是否达到施工要求。
As compared with full support method and reserved hole method, wrapping hoop method has obvious advantages, such as simple construction operation, material-saving, labor-saving and short cycle etc. The construction of a coping by embracing hoop method needs close calculations, mainly including： the calculation of side formwork support, calculation of longitudinal beam and that of wrapping hoop. Taking the pier coping of the separation overpass on Zhengzhou K0 ＋ 514 line crossing the Beijing- Guangzhou Railway for example, the wrapping hoop stress was checked during construction of the coping, if it could meet the construction requirements.
