Description
Technical Field
[0001] The utility model relates to the technical field of building drainage, and particularly relates to a building roof drainage system. Background Art
[0002] In cities, high-rise residential buildings are mainly used. The drainage of the roof is particularly important. Since the rooftops of buildings are mostly flat roofs, rainwater on the roof is mainly discharged by opening drainage grooves on the roof and cooperating with drain pipes.
[0003] This drainage method is the simplest and most practical. However, for buildings with high waterproof requirements on the roof, existing roof waterproofing mostly uses waterproof coiled materials for laying. During the long-term use process, the waterproof raw materials are easily damaged by wind and sun, and the waterproof layer is damaged. When it rains, rainwater easily penetrates downward through the roof, causing losses to the top-floor residents.
[0004] Therefore, it is very necessary to invent a building roof drainage system to solve the above problems. Content of the Utility Model

[0033] Among them, through the double - floor slab design, the first waterproof coiled material layer 19 and the second waterproof coiled material layer 110 are respectively laid on the surfaces of the first concrete floor slab 1 and the second concrete floor slab 16. The second concrete floor slab 16 makes the first blockage of rainwater. A large amount of rainwater is collected into the interior of the first water collecting pipe 21 through the second water guide groove 17 on the surface of the second concrete floor slab 16, so that the rainwater is quickly discharged. When water seepage occurs in the second concrete floor slab 16 during long - term use, the seeping rainwater will drip onto the surface of the first concrete floor slab 1. Since the first waterproof coiled material layer 19 is located inside, it will not be eroded by rainwater and sunlight, and its service life is relatively long. A small amount of rainwater will not cause leakage, thus effectively improving the sealing performance of the roof. At this time, the first water guide groove 12 on the surface of the first concrete floor slab 1 collects the rainwater into the interior of the second water collecting pipe 23, improving the drainage speed of the roof and effectively avoiding rainwater leakage.
[0034] Refer to Figure 3 and Figure 5 , in the middle position of the surface of the first concrete floor slab 1, a plurality of support blocks 14 are fixedly connected. The first drain pipe 2 is erected on the upper side of the plurality of support blocks 14. The first water collecting pipe 21 is fixed to the front and rear sides in the middle of the first drain pipe 2. A plurality of first connecting pipes 22 are fixedly connected to the surface of the first water collecting pipe 21. The second water collecting pipe 23 is fixedly connected to the front and rear sides at both ends of the first drain pipe 2. A plurality of second connecting pipes 24 are fixedly connected to the surface of the second water collecting pipe 23. The first water guide groove 12 is arranged in a criss - cross pattern on the surface of the first concrete floor slab 1. Second drain holes 111 are opened at the positions of the left and right sides of the concrete water retaining beam 11 on the surface of the first water guide groove 12. The second connecting pipes 24 are fixedly connected to the second drain holes 111.

The upper ends of the first connecting pipes 22 are fixedly connected to the first drain holes 18.
[0035] Specifically, the rainwater on the surface of the second concrete floor slab 16 is collected into the interior of the first connecting pipe 22 through the second water guide groove 17. Then, the water flow inside the first connecting pipe 22 is collected into the interior of the first water collecting pipe 21, and then the water flow inside the first water collecting pipe 21 is collected into the interior of the first drain pipe 2. When the second concrete floor slab 16 leaks, the rainwater will drip onto the surface of the first concrete floor slab 1. The rainwater on the surface of the first concrete floor slab 1 is collected into the interior of the second connecting pipe 24 through multiple groups of first water guide grooves 12. Then, the rainwater inside the second connecting pipe 24 is collected into the interior of the second water collecting pipe 23, and the rainwater inside the second water collecting pipe 23 is collected into the interior of the first drain pipe 2. The rainwater discharged from the first drain pipe 2 flows into the interior of the second drain pipe 3. Then, the filter box 31 filters the rainwater inside the second drain pipe 3, and the filtered rainwater is input into the interior of the water storage tank 33 through the third drain pipe 32 for storage and used for daily use.
[0036] The working principle of the present utility model: Through the double-layer floor design, waterproof coiled materials are laid on the surface of each floor, effectively improving the sealing performance of the roof. Then, through the cooperation of the first water guide groove 12, the second water guide groove 17, the first drain pipe 2, the first water collecting pipe 21, and the second water collecting pipe 23, the drainage speed of the roof is increased, effectively avoiding rainwater leakage, and through the cooperation of the second drain pipe 3, the filter box 31, and the third drain pipe 32, the rainwater is collected into the interior of the water storage tank 33.
