大瓦屋面如有烟囱,其结合部的防水处理,应引起注意。我们在施工中采取了一个简易的方法,现介绍如下: 把烟囱上面受烟囱影响流水的第二层瓦的滴水打掉(如图1),在其下面,下一层瓦的上面接头处打上水泥砂浆,使打掉滴水的瓦与下面的瓦良好连接。然后根据瓦下水泥砂浆的厚度引出水泥砂浆至烟囱处(如图2)。其它三面用水泥砂浆抹死,防止水的侵 If there are chimneys in large tile roofs, the waterproof treatment of the joints should attract attention. We have adopted a simple method in construction. Now we introduce the following: 1. Drop the dripping water from the second floor of the chimney, which is affected by the chimney (see Figure 1). Underneath it, put the upper layer of the tile above the joint. The cement mortar makes the dripping tile well connected with the tile below. Then according to the thickness of the tile cement mortar to draw out the cement mortar to the chimney (Figure 2). The other three sides are wiped with cement mortar to prevent the invasion of water
