Construction method of splicing seam drainage pipe of prefabricated outer wall of assembly type concrete building
The invention relates to building construction, in particular to a construction method of a splicing seam drainage pipe of a prefabricated outer wall of an assembly type concrete building. The constructing method comprises the steps that a splicing seam is cleared, a foam round bar lining is plugged into a splicing seam cavity, the splicing seam is filled with sealant, and when the splicing seam is filled with the sealant, glue injection is conducted on the foam round bar lining, wherein before glue injection, an adhesion face is coated with a layer of prime coat liquid, after 5-10 minutes, the sealant is tightly attached to the foam round bar lining for glue injection, and the sealant is tightly attached to a backing material and connected with the inner walls of the three sides of the splicing seam, so that a drainage cavity subsection is formed; then, another foam round bar lining is plugged into a splicing seam cavity needing to be used as a drainage opening, glue injection is conducted, and then a drainage slope is formed; and the drainage pipe is installed on the glue face of the slope in an inclined manner. By utilizing the principle that the drainage pipe discharges waterin one direction, condensate water generated when the internal temperature and external temperature of the drainage cavity are different and the rainwater entering the cavity when the sealant of the outer wall is damaged or adhesion is ineffective are discharged, and it is avoided that external rainwater and insects enter the cavity through the drainage pipe.
本发明专利涉及建筑施工，具体涉及装配式混凝土建筑预制外墙拼缝排水管施工方法，包括清理接缝、将泡沫圆棒衬垫塞入接缝空腔、对接缝处填充密封胶，对接缝处填充密封胶时，对泡沫圆棒衬垫进行注胶；注胶前先在粘接面涂刷一层底涂液，5‑10分钟后将密封胶贴紧泡沫圆棒衬垫注胶，使密封胶贴实背衬材料并与接缝三侧内壁相接，形成一个排水空腔分段；然后在需要作为排水口的接缝空腔塞入另一根泡沫圆棒衬垫，注胶，形成排水斜坡；将排水管倾斜安装在斜坡胶面上。利用排水管单向排水的原理，将排水空腔因内外温度不一致时产生的冷凝水，以及外墙密封胶破损或粘接失效时，进入空腔的雨水排出，同避免外界雨水和昆虫通过排水管进入空腔。
