Sloping roof double-face formwork concrete pouring and tamping construction process
The application relates to a sloping roof double-face formwork concrete pouring and tamping construction process, and relates to the technical field of building construction. The sloping roof double-face formwork concrete pouring and tamping construction process comprises the following steps that pouring and tamping section division is conducted on the width of a single-face roof in the inclined direction, the single-time pouring and tamping width is smaller than or equal to 900mm, and a reserved pouring belt with the width smaller than or equal to 400mm is arranged in the middle; and a pouring and tamping reserved opening is formed in s surface layer formwork. A bottom-layer formwork, a reinforcement cage and the surface-layer formwork are laid and fixed according to design requirements,and a plurality of fixing mechanisms which are evenly distributed and used for limiting the distance between the bottom-layer formwork and the surface-layer formwork are installed between the bottom-layer formwork and the surface-layer formwork; during concrete pouring, graded symmetrical pouring is conducted from bottom to top, and the pouring direction is gradually conducted in the direction parallel to the ridge length direction; tamping operation is conducted while pouring is conducted, supplementary tamping is conducted from the pouring and tamping reserved opening, and after pouring andtamping, a middle cover plate is immediately fixed to the reserved pouring belt in a covering mode; and after maintenance meets the design requirement, form removal is conducted. The sloping roof double-face formwork concrete pouring and tamping construction process has the advantage that the compactness of sloping roof concrete is improved.
本申请涉及一种斜屋面双面支模混凝土浇捣施工工艺，涉及建筑施工技术领域，包括以下步骤：对单侧屋面在倾斜方向的宽度进行浇捣区段划分，单次浇捣宽度≤900mm，中间设置宽度≤400mm的预留浇筑带；在面层模板上设置浇捣预留口；根据设计要求铺设固定底层模板、钢筋笼以及面层模板，底层模板与面层模板之间安装有多个均匀分布的用于限制两者距离的固定机构；浇筑混凝土时从下往上分级对称浇筑，浇筑方向沿着平行于屋脊长度方向逐步进行；边浇筑边进行捣实操作，从浇捣预留口补充捣实，浇筑捣实后立即在预留浇筑带上盖合固定中间盖板；养护达到设计要求后拆模。该申请具有提高斜屋面混凝土密实度的优点。
