Technical Field
The invention relates to the technical field of building waterproofing, in particular to an inverted roof water falling port structure for material slope finding.
Background
The main waterproof layer is arranged under the heat-insulating layer. Due to the encouragement of over short guarantee period (5 years), a secondary waterproof layer (arranged below a slope finding layer) is sometimes added, and the negative effects of various factors on the site are added, so that the leakage rate of the roof is as high as 50%, which means that each layer above the structural slab has higher leakage rate. Because the water seepage can not be discharged, the water is accumulated in the heat preservation layer and the slope finding layer, the leakage rate of the roof is increased dramatically in successive years, and the energy is saved and the like. Therefore, attempts should be made to drain the seeping water in the two layers in time.
Set up the outlet alone, make the weak node figure of waterproof increase, and the degree of difficulty that is used for two-layer sluicing is very big. When the rainfall is large and the water blocking occurs at the water gap, the backflow water enters the water to flow through the water outlet greatly. Therefore, a novel water falling port is designed, which can discharge seeper water in the heat-insulating layer and the slope finding layer simultaneously and prevent open water from flowing backwards when the water collection amount is large. It is the object of the present invention.
