Anti-seepage structure for split bolt hole of building outer wall and construction method of anti-seepage structure
According to the anti-seepage structure for the split bolt hole of the building outer wall, the middle of the split bolt hole of the outer wall is filled with a sealing plug, the outer side of the sealing plug is filled with outer side sealing mortar, and the inner side of the sealing plug is filled with inner side sealing mortar; a mortar cake is formed at the outer end of the outer side plugging mortar, and the outer surface of the mortar cake is coated with a polyurethane waterproof coating layer. The construction method comprises the following steps: a) supporting a template; b) supporting keels; c) penetrating a split bolt; d) oppositely pulling the bolts; e) pouring and maintaining; (f) removing the template; (g) chambering and cleaning; h) placing a sealing plug; j) filling plugging mortar; and k) brushing waterproof paint. According to the split bolt hole anti-seepage structure and the construction method, the inner formwork and the outer formwork are arranged in the mode that the height of the round hole, where the same split bolt penetrates through, in the inner formwork is higher than that of the round hole in the outer formwork, and after pouring of an outer wall is completed, the split bolt hole with the lower outer portion and the higher inner portion is formed, and it is guaranteed that the split bolt hole does not leak.
本发明的建筑外墙对拉螺栓孔防渗结构，外墙的对拉螺栓孔的中部填塞有封堵塞，封堵塞外侧填充有外侧封堵砂浆，封堵塞内侧填充有内侧封堵砂浆；外侧封堵砂浆的外端形成有灰饼，灰饼的外表面涂刷有聚氨酯防水涂料层。本发明的施工方法，包括：a).支护模板；b).支护龙骨；c).穿对拉螺栓；d).螺栓对拉；e).浇筑和养护；f).拆模板；g).扩孔和清理；h).置入封堵塞；j).填筑封堵砂浆；k).涂刷防水涂料。本发明的对拉螺栓孔防渗结构及施工方法，内、外模板按照“同一对拉螺栓穿过的内模板上的圆孔高度比外模板上的圆孔高”的形式布置，外墙浇筑完成后，就形成了外低内高的对拉螺栓孔，确保了对拉螺栓孔不渗漏。
