梁板后浇带模板施工的传统工艺同普通梁板支模方法 ,即采用顶撑加固 ,但其存在不易克服的缺点 :因后浇带两侧楼板混凝土一般于 2个月前进行浇灌 ,楼板结构已基本稳定 ,于旧混凝土楼板底顶撑很难做到完全密合 ,且后浇带混凝土浇灌过程中顶架系统不可避免地存在微沉降变形 ,新旧?
The traditional process of slab post-pouring tape formwork is the same as that of common beam slab support method, that is, the use of top support reinforcement, but its drawbacks are not easily overcome: the concrete slabs on the two sides of post-pouring tape are generally irrigated two months ago, The structure has been basically stable, it is very difficult to be completely close to the bottom support of the old concrete floor, and the micro-settlement deformation of the top support system inevitably occurs in the process of pouring the concrete with the pouring zone.
