Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, in order to the utility model discloses a parapet 2 drain port waterproof structure, including the parapet 2 and the pipe in the water 3 that set up at the edge of roof 1, the pipe in the water 3 includes inlet tube 31 and outlet pipe 32, and inlet tube 31 sets up the lower tip at the parapet 2, makes the lower tip of inlet tube 31 contact the upper surface of roof, and outlet pipe 32 sets up the tip that deviates from roof 1 at inlet tube 31, and the export of outlet pipe 32 is towards the below; a slope finding layer 11 is laid on the roof 1, and the inlet of the downpipe 3 is arranged at the bottom of the slope finding layer 11; a waterproof layer 12 is arranged above the slope finding layer 11, and the side edge of the waterproof layer 12 is arranged on the side surface of the parapet wall 2.

In rainy days, the waterproof layer 12 laid on the roof 1 can protect the roof 1 and prevent rainwater from directly falling on the upper surface of the roof and directly contacting the roof; the slope finding layer 11 arranged on the roof can enable rainwater falling on the roof to move along the slope of the slope finding layer 11, and the rainwater is prevented from being gathered on the roof; the inlet pipe 31 of the downpipe 3 is arranged at the lower part of the parapet wall 2, the axis of the inlet pipe is vertical to the edge of the roof, and the inlet pipe is positioned at the bottom of the slope of the roof slope-finding layer 11, so that rainwater at the bottom of the slope can be discharged from the downpipe 3, and the erosion damage of the rainwater to the roof 1 is reduced.
