AI Technical Summary
Existing technologies cannot simultaneously guarantee waterproofing and thermal insulation performance in the parapet wall drainage structure of high-rise buildings, leading to problems such as water seepage in the waterproof layer or rainwater overflow from the roof.
The system employs a combination structure of drainage pipes, polyurethane foam, sealant, and asphalt waterproof sleeve. Combined with the drainage hole design of the roof and parapet wall, polyurethane foam provides support and waterproofing, sealant increases sealing, asphalt waterproof sleeve enhances waterproofing performance, and rain grate filters out debris. The drainage pipes are connected to the drain pipes to ensure smooth water flow.
It achieves a balance between waterproofing and thermal insulation performance of the parapet wall drainage structure in high-rise buildings, avoiding water seepage in the waterproof layer and rainwater runoff from the roof, thus improving the overall waterproofing and thermal insulation effect.

The asphalt waterproof sleeve improves the waterproof performance of the water guide drain pipe, and the asphalt waterproof sleeve extends to the inside of the roof structure.
[0006] Preferably, a rainwater grate is arranged in the water guide drain pipe, and the edge of the rainwater grate is attached to the asphalt waterproof sleeve. The rainwater grate filters rainwater to prevent large debris from entering the drain pipe.
[0007] Preferably, a drain pipe is fixedly connected to the side wall of the outer wall structure, and one end of the water guide drain pipe is bent and extends to the inside of the upper end of the drain pipe.
[0008] Preferably, a sealing paste is arranged in the middle of the upper end of the outer wall structure, and the sealing paste is located above the outer wall insulation board in the outer wall structure. That is, the sealing paste seals the upper end of the outer wall insulation board.
[0009] Preferably, the roof structure around the water guide drain pipe is a slope. It is beneficial for rainwater to flow smoothly into the water guide drain pipe.
[0010] Preferably, the type of the sealing glue is silicone glue.
[0011] The beneficial effects of the present application are as follows: the water guide drain pipe and the drain pipe are provided, the drainage of the roof structure is ensured, and the polyurethane foam, the sealant and the asphalt waterproof sleeve and other structures are provided at the water guide drain pipe, the drainage structure is ensured, and the waterproof and heat preservation of the building is not damaged.
