Fabricated concrete building prefabricated external wall panel bottom waterproof process
The invention belongs to the technical field of building waterproofing, and provides an assembly type concrete building prefabricated external wall panel bottom waterproof technology which comprises the steps that a prefabricated concrete water blocking block is prepared; paying off and paving prefabricated concrete water-blocking blocks; pressing the prefabricated concrete water-blocking block into the laminated layer cast-in-place concrete; the reserved elevation of the water blocking block is corrected according to a field elevation control line; the prefabricated concrete water blocking blocks and floor cast-in-place concrete are condensed and formed, and an integral water blocking reverse ridge is formed; laying a prefabricated external wall panel mounting cushion block, and adjusting the elevation of the cushion block to ensure the mounting elevation of the wall panel; paving bedding material with corresponding thickness along the plastic cushion block; and hoisting and mounting the prefabricated external wall panel. In the invention, when mortar has gaps due to construction quality problems of materials between the second prefabricated external wall panel on the upper layer and the first prefabricated external wall panel on the lower layer, external rainwater enters from leakage points, and the prefabricated concrete water-blocking blocks, the cavities and the micro-expansion mortar form blocking points, namely, two materials are waterproof and one structure is waterproof; and water cannot leak into a room.
本发明属于建筑防水技术领域，提供了一种装配式混凝土建筑预制外墙板底部防水工艺，包括准备预制混凝土阻水块；放线铺装预制混凝土阻水块；将预制混凝土阻水块压入叠合层现浇混凝土；根据现场标高控制线校正阻水块预留标高；令预制混凝土阻水块与楼板现浇混凝土凝结成型，形成整体阻水反坎；铺设预制外墙板安装垫块，并调整垫块标高，保证墙板安装标高；沿塑料垫块铺设相应厚度坐浆料；吊装安装预制外墙板。本发明中，上层的第二预制外墙板与下层的第一预制外墙板之间的材料因为施工质量问题导致砂浆出现空隙时，外界的雨水从渗漏点进入，预制混凝土阻水块、空腔和微膨胀砂浆构成阻挡点，即两道材料防水和一道结构防水，使水无法渗漏进入室内。
