压制成型的折板屋面具有良好的结构强度和十分美观的直线形外型,在国外大型建筑中已被广泛采用。但是这种金属板的材质是以镀锌铁板为主,因此存在着保温、防结露和隔音等问题,必须与保温材料同时使用,才能取得较好的效果。保温材料的粘贴可以采取各种施工方法。日本介绍的一种方法是在已加工成槽形板的一面先贴 Press-formed folding roofs have a good structural strength and a very beautiful straight-line appearance and have been widely used in large-scale foreign constructions. However, the material of the metal plate is mainly galvanized iron plate, so there are problems such as heat preservation, anti-condensation and sound insulation, and it must be used together with the heat insulating material in order to obtain better results. Paste insulation materials can take various construction methods. One method introduced in Japan is to paste on the side that has been processed into a grooved plate.
