Construction method for preventing interface cracks of fair-faced concrete wall and filler wall
The invention discloses a construction method for preventing interface cracks of a bare concrete wall and an infilled wall, which mainly comprises the following steps of: reserving a tongue-and-groove on the bare concrete shear wall at the junction of the bare concrete shear wall and the infilled wall to be leveled, pre-burying an anti-crack steel wire mesh, and flatly paving and fixing the other end of the steel wire mesh on the surface of the infilled wall masonry; a splayed opening is reserved on one side, tightly attached to the concrete, of the junction of the two wall bodies, and anti-crack mortar is filled in the reserved splayed opening. According to the invention, prevention, release and resistance are combined, tight combination of the fair-faced concrete wall and the infilled wall is enhanced, and measures are taken to enable the wall body to form a whole, so that the anti-seismic effect is enhanced; and by reinforcing anti-cracking measures at interfaces of different materials, the probability of occurrence of cracks is effectively prevented.
本发明公开了一种清水混凝土墙与填充墙预防界面裂缝施工工法，它主要是在需要抹平的施工清水混凝土剪力墙与填充墙交界处的清水混凝土剪力墙上留设企口并预埋抗裂钢丝网，钢丝网另一端平铺固定在填充墙砌体表面处，并在二者墙体交界处紧贴混凝土一侧预留一个八字口，在预留的八字口内填充抗裂砂浆。本发明将防、放、抗相结合，通过加强清水混凝土墙与填充墙的紧密结合，并采取措施使墙体形成整体，增强抗震效果；通过加强不同材料界面处的抗裂措施，有效防止裂缝发生的几率。
