本文介绍倒置屋面的进一步发展,使之能蓄水和减少房屋的初次投资。 如图,将保温面板放在小型支墩上,板下面的空间用来集中和储存雨水,而用于建筑物的厕所冲洗。当然,为了保持连续的用水,亦应由主水管补给屋面蓄水。 节约建筑物初次投资的主要原因是无需惯用的雨水排出系统,既无落水,也无天 This article describes the further development of inverted roofs so that they can store water and reduce the initial investment in housing. As shown in the figure, the insulation panel is placed on a small pier, the space under the panel is used to concentrate and store rainwater, and the toilet for the building is flushed. Of course, in order to maintain continuous water use, the main water supply should also be used to supply water to the roof. The main reason for saving the initial investment in a building is to eliminate the need for a customary rainwater drainage system.
