Anti-leakage structure of high-rise building

The invention relates to the field of high-rise building anti-seepage technologies, in particular to a high-rise building anti-seepage structure which comprises an outer wall with a screw hole and a concrete layer used for blocking the screw hole, a step cavity is formed in one end of the screw hole, a water baffle is laid in the step cavity and covers the screw hole, and the concrete layer is arranged on the outer wall. And the screw holes and the stepped cavity are filled with the concrete layer. The water baffle has the water blocking effect on the screw hole, the possibility that water permeates into a room from the screw hole is reduced, the anti-seepage effect of a building wall at the screw hole is improved, and the using effect of a building outer wall is improved. 本申请涉及高层建筑防渗技术的领域，尤其是涉及一种高层建筑防渗漏结构，包括具有螺杆眼的外墙和用于将螺杆眼封堵的混凝土层，所述螺杆眼一端开设有阶梯腔，所述阶梯腔内铺设有挡水板，所述挡水板将螺杆眼覆盖，所述混凝土层将螺杆眼及阶梯腔填充。本申请挡水板对螺杆眼具有水分阻隔的作用，减小水分从螺杆眼内向室内渗透的可能性，改善建筑墙体在螺杆眼处的防渗效果，提高建筑外墙的使用效果。
