Description

Technical Field

[0001] The utility model belongs to the technical field of building roofs, and in particular relates to a building drainage roof with a circumferential self-sealing composite structure. Background Art

[0002] Roof refers to the surface of the roof of a building, and also refers to the part between the ridge and the eaves. Roofs generally include cast-in-place concrete floors, cement mortar leveling layers, thermal insulation layers, waterproof layers, cement mortar protective layers, drainage systems, parapets, and lightning protection measures. In special projects, there is also tile construction (tile hanging strips). When draining, the roof is divided into internal and external drainage types. The external drainage type is not convenient to install and the later maintenance is complicated. The internal drainage type is easy to install and convenient for later maintenance. When the roof is constructing an internal drainage rainwater pipe, it is necessary to install a rainwater pipe in the house, but the roof and the space between the roof and the rainwater pipe need to be waterproofed with waterproof membranes. However, the following problems may occur when the waterproof membrane is used:

[0003] 1. Due to the lack of standardized and unified sealing methods, gaps will appear between the internal rainwater pipes and the roof. Rainwater seeping from the gaps will further infiltrate and erode the surrounding structures of the cracks, making the surface prone to cracking and aggravating the degree of cracking. During roof renovation, the cracks open to different degrees. Due to the requirements of combining design and construction, the shapes and diameters of the internal rainwater pipes are different at different positions, and most of them are arranged in a conical shape. When the outer wall shape of the conical pipe is configured on the roof, it is easier to form a rainwater infiltration channel. Repair by filling with glue can only achieve short-term sealing, and cannot fundamentally solve the problem of cracking and leakage. It needs to be removed and waterproofed again. This process is more complicated and lacks a unified treatment method.

[0004] Second, the waterproof layer of the roof will also crack and peel off when exposed to the sun for a long time. When rainwater is washed away, it will enter the room through the roof, causing water to enter the room.

[0005] 3. The upper end of the internal drainage pipe needs to be blocked by a filter to prevent leaves and other debris from clogging the rainwater pipe. However, when draining water, leaves or other flaky debris will clog the filter. Due to the lack of timely treatment measures and timely cleaning measures, the rainwater cannot be discharged in time.
