以往的屋面外隔热施工法,是在防水层上安放隔热材料,再浇筑混凝土。承受直接荷载的隔热材料由于雨、雪而含水,天长日久,难免会降低隔热性能。日本新近开发的WPS板施工法可以克服上述缺点,提高和保持隔热材料的性能,且构造简单,施工方便。WPS板法是在防水层上设置简单的现场制作的支撑脚(用氯乙烯管子内填砂浆制成),其上安装预制混凝土板(WPS板)。由于
In the past, the method of heat insulation outside the roof was to place a heat-insulating material on the waterproof layer and then poured the concrete. Thermal insulation materials subjected to direct loads will contain water due to rain and snow. As time passes, it will inevitably reduce the thermal insulation performance. The newly developed WPS board construction method in Japan can overcome the above disadvantages, improve and maintain the performance of heat insulation materials, and has a simple structure and convenient construction. The WPS board method is to install a simple on-site support foot (made of vinyl chloride pipe filled with mortar) on the waterproof layer, and install a prefabricated concrete board (WPS board) thereon. due to
