沥青油毡瓦施工技术

CONSTRUCTION TECHNOLOGY OF BITUMINIZED TILE

沥青油毡瓦是集装饰、防水双重功能于一体的柔性瓦片。沥青油毡瓦不宜用于坡度小于１∶６的屋面，坡度介于１∶６～１∶３之间的屋面，必须在沥青油毡瓦下增加防水层，坡度在１∶３以上的屋面最适合沥青油毡瓦使用，防水效果最好。该材料已在北京古城地铁车辆段改扩建工程中大面积使用。

The bituminized tile has been made of an ornamental and waterproofing flexible tile.The bituminized tile,however,should not be adopted in roof construction's slope less than 1∶6.As for roof slope between 1∶6 and 1∶3,there should have been another waterproofing layer provided under it.While its appilcation at a roof slope of 1∶3 and bigger,it would be the most appropriate choice and the best waterproofing material.It has been implemented widely in the extension work of the Beijing Subway project.
