刚性蓄水屋面是直接利用混凝土作为防水层的蓄水屋面,它充分发挥了水硬性材料的特点。敞开式蓄水屋面既能隔热、保温,也能防水,还可避免混凝土碳化风化。这种屋面构造简单,即在钢筋混凝土屋面板上做混凝土防水层就可蓄水,屋面板以预制为宜。对施工并无要求,但应注意: (1)为了使防水层和嵌缝处形成整体,防止振捣时漏浆,浇捣前一天应先将板缝嵌5～6厘米,留下部分待做防水层时一起浇灌,用平板振捣器振捣密实,原浆收光,不留施工缝,加强养护并及时蓄水。
The rigid water storage roof is a water storage roof that directly uses concrete as a waterproof layer, and it fully utilizes the characteristics of hydraulic materials. The open storage roof can not only be insulated and insulated, but also waterproof, and it can also avoid the weathering of concrete carbonization. This kind of roof structure is simple, that is, concrete waterproof layer can be used to store water in the reinforced concrete roof, and the roof panel is suitable for prefabrication. There is no requirement for construction, but care should be taken: (1) In order to make the waterproof layer and the caulking to form an integral part and to prevent leakage of slurry during vibrating, the slab should be embedded 5 to 6 centimeters before the pouring day to leave some parts to be left. When the waterproof layer is used for watering, the plate vibrator is used for vibrating and compacting, the raw slurry is collected, no construction joints are left, and the conservation is maintained and the water is filled in time.
