    • A draining system for water which may collect between the upper and lower membranes of flat, horizontal or slightly sloped insulated roofs upon perforation of the upper membrane. The insulating panels located between the two membranes are provided at both their upper and lower faces with a network of intersecting grooves, and these networks communicate with each other through passages made through the insulating panels or constituted at the panel joints. A lower drain member is sealed to and opens above the lower membrane to drain any water having seeped under the broken or perforated upper membrane, so as to prevent deterioration of the insulating panels and water accumulation which may provoke considerable roof overload problems. In certain roof constructions, the network of upper grooves is not necessary.
    • 一种用于水的排水系统,其可以在上膜穿孔时在平坦的,水平的或稍倾斜的绝热屋顶的上下膜之间收集。 位于两个膜之间的绝缘板在它们的上表面和下表面都设有相交槽的网络,并且这些网络通过通过绝缘板制成的通道或在面板接头处构成的通道相互连通。 下排水构件被密封到下膜上方并且在下膜上方打开以排出在破裂或穿孔的上膜下方渗出的任何水,以防止绝缘板的劣化和积水,这可能引起相当多的屋顶过载问题。 在某些屋顶结构中,上槽的网络不是必需的。
