Layered construction method for large-area bare concrete wall
The invention discloses a layered construction method for a large-area fair-faced concrete wall. The layered construction method comprises the following steps that S1, a formwork is erected, and an old wall is poured; s2, an inclined flow guide plate is erected on the outer side of the old wall body; s3, laying a plastic leakage-proof film; s4, a new wall formwork is installed, specifically, an outer formwork and an inner formwork are fixed to the upper portion of the old wall through opposite-pull screws, meanwhile, an exposed joint strip is plugged into an exposed joint strip installation opening, and a sealing gasket I and a sealing gasket II are correspondingly fixed to the front side face and the rear side face of the exposed joint strip correspondingly; s5, pouring of an upper-layer wall body; s6, form removal is conducted, the new wall serves as an old wall of the next layer, and construction of the wall of the next layer is started till construction of the whole wall is completed; construction steps are simple, overall investment is low, operation is easy, and construction is easy; by adopting the construction method, the technical problems that the forming quality of the fair-faced concrete joint is poor, the root is easy to rot, the root of the joint of the new wall and the old wall is easy to lose water and leak slurry, and the finished product is not protected in place can be obviously reduced.
本发明公开了一种大面积清水混凝土墙体分层式施工方法，包括如下步骤：S1：支模浇筑老墙体；S2：在老墙体的外侧搭设斜向导流板；S3：铺设塑料防漏薄膜；S4：新墙体模板安装：通过对拉螺杆将外模板和内模板固定到老墙体的上部，同时在明缝条安装口处塞入明缝条，明缝条的前后侧面分别对应的固定有密封垫Ⅰ和密封垫Ⅱ；S5：上层墙体浇筑；S6：拆模，并将新墙体作为下一层的老墙体开始下一层墙体的施工，直至整个墙面施工完；施工步骤简单，整体投入低，操作简单，易于施工；采用该种施工方法，可显著减小清水混凝土接缝处成型质量差，容易烂根，新老墙体接缝处根部易失水漏浆，以及成品保护不到位的技术问题。
