Overground outer wall anti-seepage structure and construction method
The invention provides an overground outer wall anti-seepage structure, a lower structure is composed of an upper layer floor and a lower layer outer wall, and the overground outer wall anti-seepage structure further comprises a 300mm upper layer outer wall bottom guide wall constructed on the upper layer floor; the construction method of the overground outer wall anti-seepage structure comprises the steps that firstly, an upper-layer floor slab and a lower-layer outer wall formwork are constructed according to a conventional method, the top of a guide wall outer formwork is lifted to be 300 mm higher than the upper-layer floor slab, and the top of an outer formwork reinforcing batten is lifted to be 500 mm higher than the upper-layer floor slab; the guide wall inner side formwork is fixed in a formwork hanging mode, the height of the guide wall inner side formwork is 300 mm, and the height of a reinforcing batten of the guide wall inner side formwork is 500 mm. When pouring to the top, the wall body inside the angle steel is filled into a high table top, and the space outside the angle steel is reserved as a low table top; the upper structure outer wall formwork is mounted and spliced with the lower structure outer wall formwork, the lower structure outer formwork is not detached during concrete pouring, the self-waterproof anti-seepage capacity of the outer wall structure is effectively improved by heightening the position of the construction joint and optimizing the internal structure, and the problems of concrete slurry leakage and voids and pitted surfaces at the joint are solved.
本发明提供一种地上外墙防渗漏结构，下部结构由上层楼板和下层外墙组成，还包括在上层楼板之上施做的300mm的上层外墙底部导墙；所述地上外墙防渗漏结构的施工方法，先按常规做法施工上层楼板及下层外墙模板，导墙外模板顶部提升至高于上层楼板300mm，外模板加固木方顶部提升至高于上层楼板500mm；导墙内侧模板以吊模形式固定，导墙内侧模板高度为300mm,其加固木方高度为500mm；浇筑至顶部时角钢内侧墙体填充为高台面，角钢外侧留空为低台面；安装上部结构外墙模板，其与下部结构外墙模板拼接，混凝土浇筑时不拆除下部结构外模板，本发明通过施工缝位置调高及内部结构优化，有效提高外墙结构自防水的防渗漏能力，减少交接处混凝土漏浆、蜂窝麻面问题。
