柔性防水屋面的传统做法是在基层上做水泥砂浆或是细石混凝上找平层,然后刷冷油一度,再做二毡三油(如图一、图二)。图一①面层:二毡三油②结合层:冷底子油③找平层:水泥砂浆或细石混凝土④基层:多孔板⑤粉刷层图二①面层②结合层③找平层④基层:现浇混凝土⑤粉刷层这种做法有三个缺点:一是基层潮湿,油毡容易起泡鼓壳。二是受天气影响较大,一旦下雨,基层和找平层不干,就必须等
The traditional approach of flexible waterproof roofing is to do cement mortar on the grass-roots level or levelling layer on the fine stone coagulation, then brush the cold oil once, and then do two felts and three oils (Figure 1, Figure 2). Fig. 1 1 surface layer: two felts and three oils 2 Bonding layer: cold bottom oil 3 leveling layer: cement mortar or fine stone concrete 4 base layer: perforated plate 5 paint layer Fig. 2 1 surface layer 2 bonding layer 3 leveling layer 4 base layer: present There are three disadvantages to this practice: The first layer is damp and the linoleum foams easily. The second is that it is affected by the weather. Once it rains, the grass roots and the screed are quit, they must wait.
