Waterproof construction method for joint of parapet root and roof concrete structure

The invention discloses a waterproof construction method for a joint of a parapet root and a roof concrete structure. A parapet is upturned by 300mm, and a roof panel and a parapet breast board structure form a structural waterproof ring in the range of 300mm above a roof. A roof leveling layer, a slope making layer, a waterproof layer and a protective layer are stacked at the parapet root and are generally not larger than 250mm, even if the roof waterproof layer is aged and leaks, water is accumulated on the heat preservation layer leveling layer for a long time, the roof panel and the parapet breast board structure cannot generate the water seepage phenomenon in the waterproof ring range of 300mm above the roof structure layer, and therefore the influence of water seepage of the roof parapet root on water immersion of an outer wall and a top layer indoor wall face is eradicated. 本发明公开了一种女儿墙根部与屋面混凝土结构交接处的防水施工方法，将女儿墙上翻300mm高，屋面板与女儿墙栏板结构在屋面向上300mm范围形成结构防水圈。屋面找平层、找坡层、防水层、保护层叠加在女儿墙根部部位一般小大于250mm，即使屋面防水层老化、渗漏，致使保
