Fabricated concrete structure outer wall anti-crack and anti-seepage structure device and construction method
The invention provides an anti-crack and anti-seepage construction device for an outer wall of a fabricated concrete structure and a construction method.The anti-crack and anti-seepage construction device is characterized in that a splicing seam is formed between a prefabricated concrete wall plate A and a prefabricated concrete wall plate B, and pressing grooves in the length direction of the splicing seam are formed in the corresponding positions of the outer wall edges of the prefabricated concrete wall plate A and the prefabricated concrete wall plate B; semicircular notches are formed in the sides, close to the inner wall edge, of the prefabricated concrete wallboard A and the prefabricated concrete wallboard B, a splicing seam is filled with a polyethylene foaming core rod, hollow rubber pipe water stop strips are embedded in the two semicircular notches, and the outer side of the polyethylene foaming core rod and the outer sides of the hollow rubber pipe water stop strips, namely the inner wall side, are filled with polyurethane sealant waterproof layers. The anti-crack mortar layer is arranged on the outer side of the polyurethane sealant waterproof layer. According to the device and the construction method, the construction space of the anti-crack mortar layer is reserved, and the defect that the construction quality cannot be guaranteed due to cracking and leakage at the splicing seam of the existing fabricated external wall panel is overcome by arranging the anti-crack mortar layer.
本发明提供一种装配式混凝土结构外墙抗裂防渗构造装置及施工方法，该装置预制混凝土墙板A与预制混凝土墙板B之间设有拼接缝，预制混凝土墙板A与预制混凝土墙板B的外墙边对应位置处均设有沿拼接缝长度方向的压槽，预制混凝土墙板A与预制混凝土墙板B靠内墙边一侧均设有半圆形槽口，拼接缝内填充有聚乙烯发泡芯棒，两个半圆形槽口内嵌有中空橡胶管止水条，聚乙烯发泡芯棒的外侧和中空橡胶管止水条外侧即内墙侧填塞有聚氨酯密封胶防水层，抗裂砂浆层设置在聚氨酯密封胶防水层外侧。本发明装置和施工方法预留出了抗裂砂浆层施工空间，通过设置抗裂砂浆层解决目前装配式外墙板拼接缝处开裂渗漏，不能保证施工质量的缺陷。
