Construction method for bottom joint of prefabricated outer wall
The invention relates to a prefabricated shear wall bottom joint treatment method which comprises the following steps: pouring a concrete construction joint according to design and specification requirements, vibrating and compacting until the concrete construction joint reaches a specified curing age; the joint surface of the construction joint is cleaned, the construction joint is chiseled inwards by a certain width, and scum, sticky dirt, stabs and other obstacles on the surface of the construction joint are completely removed; uniformly mixing the polymer cement elastic waterproof film; the construction joints are densely filled and embedded, and after the construction joints are completely dried, putty is applied twice along the construction joints; a waterproof film is smeared for the first time, then alkali-resisting glass fiber gridding cloth is laid in a wet mode, the net face of the alkali-resisting glass fiber gridding cloth is spread and flattened, and after a period of time, the waterproof film is smeared for the second time after air drying; and 6, after waterproof membrane construction is completed, follow-up construction is conducted after maintenance. According to the prefabricated shear wall bottom joint treatment method, the detail waterproof problem between building prefabricated structures and concrete structures and between the prefabricated structures can be solved, and the water permeability of buildings such as residences and industrial factory buildings is reduced.
本发明涉及一种预制剪力墙底部接缝处理的方法，方法包括：混凝土施工缝按设计及规范要求进行浇筑，振捣密实，并达到规定养护龄期；清理施工缝的缝面，施工缝向里凿除一定宽度，将施工缝表面的浮渣、粘污、突刺等障碍物全部清除干净；将聚合物水泥弹性防水膜调匀；将施工缝填嵌密实，待施工缝干透，沿施工缝批腻子两遍；涂抹第一遍防水膜，随即湿铺一道耐碱玻纤网格布，耐碱玻纤网格布的网面铺料抹平，间隔一段时间，风干后涂抹第二遍防水膜；步骤六，防水膜施工完毕，养护后进行后续施工。本发明的一种预制剪力墙底部接缝处理的方法，能解决建筑预制结构与混凝土结构及预制结构与预制结构之间的细部防水问题，降低住宅及工业厂房等建筑渗水率。
