现浇多层钢筋混凝土框架结构抗震性能好但施工难度大,工期长。采用“先安板,后浇灌”施工工艺(以下简称先安后浇法)可缩短现浇多层框架结构的施工周期。采用先安后浇法施工多层框架,就是在支好框架模板后,浇筑混凝土前,先将预制楼板安装在设计位置上,找平校正、灌完板缝后,再浇筑框架混凝土,使框架柱梁、楼梯、阳台和预制楼板以及插入块一次浇筑成整体,不再进行二次浇灌,无施工缝,增强了结构的整体性和抗震能力。这种工艺具有工期短、质量高、省工省时、节约三材、有 Cast-in-place multi-story reinforced concrete frame structures have good seismic performance but are difficult to construct and have a long construction period. The construction process of “first-in-panel, post-irrigation” (hereinafter referred to as “first-in-line post-concrete”) can shorten the construction period of cast-in-place multi-story frame structures. After the construction of the multi-layer frame using the advanced post-casting method, after the concrete frame formwork is supported, the prefabricated floor slab is installed at the design position before the concrete is poured. After leveling and correcting, the slab joint is poured, and then the frame concrete is poured to make the frame column. Beams, stairs, balconies, and prefabricated floor slabs and insert blocks are cast in one piece at a time. No secondary irrigation and no construction joints are provided, which enhances the structural integrity and seismic resistance. This process has a short duration, high quality, save time, save three materials, there are
