目前,不少民用住宅采用内浇外挂的大模板新技术。在混凝土墙板上抹灰时,因为构件表面光滑,粘结不牢,所以,在抹灰前需要凿毛。用钢钎凿毛,人工体力消耗大,速度慢。原基建工程兵0002 4部队一连在施工中,采用了“拉毛”的办法代替凿毛,取得了较好的效果。这种做法是,先把“10 7”胶和水以1:4(重量比)的比例配好,再把1:1的水泥、砂子 (体积比)拌匀,然后把拌匀的水泥砂子倒入胶和水配成的溶液里,掺和成稀浆状,用刷子往混凝
At present, many residential houses use the new large-format new technology. When plastering concrete wall panels, because the surface of the components is smooth and the bond is not strong, it is necessary to cut the hair before plastering. With steel drill chisel, artificial physical force is consumed and slow. The 0002 4 troops of the original infrastructural engineering unit were in construction and used the method of “grooming” instead of cutting the hair, which achieved good results. This practice is to first mix the “10 7” glue and water in a ratio of 1:4 (weight ratio), mix 1:1 cement and sand (volume ratio), and then mix well. The cement sand is poured into a solution of glue and water, mixed into a slurry, and coagulated with a brush.
