传统建筑瓦屋面的檐口处理,主要注意将瓦伸出檐口檩条(或檐板)一段距离,因排水坡度较大,一般情况下不存在爬水现象。在现代建筑中,大量采用钢筋混凝土屋盖结构,其中有组织排水的屋面,只要按规范确保施工质量,做好排水口的处理,爬水现象就不会产生。现在的习惯做法及标准图中的大多做法如图1。它是用切断水源的办法形成滴水檐口的,即 In the traditional construction of tile roofs, the main concern is to extend the tiles out of the gutters (or rafts) for a certain distance. Due to the large slope of the drainage, there is no phenomenon of crawling under normal conditions. In modern buildings, a large number of reinforced concrete roof structures are used, of which there are organized drainage roofs. As long as the construction quality is ensured according to the specifications, and the drainage outlets are handled well, the phenomenon of climbing water will not occur. Most of the current practices and standard maps are shown in Figure 1. It is the use of cutting off the water to form a drip gargle, ie
