Description
Technical Field
[0001] The utility model relates to the technical field of building roofs, in particular to a roof drainage system. Background Art
[0002] Roof drainage systems are a crucial component of building design. Their primary function is to collect and direct rainwater from the roof, effectively draining it to the building's exterior to prevent structural hazards caused by roof leaks and excessive water accumulation. Conventional roof drainage utilizes organized drainage pipes. However, in extreme weather conditions where rainfall exceeds the designed return period or the drain outlets become blocked, the rainwater system fails to discharge water promptly, leading to water accumulation on the roof. Extensive water accumulation can pose a threat to building safety. Using conventional overflow outlets can result in a large amount of rainwater pouring down, impacting the building's normal use and degrading its appearance. Roof drain pipes and overflow outlets are often arranged haphazardly, impacting the building's facade. Utility Model Content

[0027] A roof drainage system 1 includes a parapet 2, a roof surface 3, a rain gutter 4, a drainage riser 5, a drain pipe 6, and an overflow pipe 7. Parapet 2 is located on one side of the top of roof 1, and rain gutter 4 is located outside parapet 2. Drain pipe 5 is vertically installed on the roof 1 on the same side as parapet 2, with the bottom of rain gutter 4 connected to the top of drainage riser 5. Roof surface 3 is located on the top of roof 1 and is tightly connected to the inner bottom of parapet 2.
[0028] In this embodiment, the rain gutter 4 has a two-chamber structure, which is used to separate the outlets of the drain pipe 6 and the overflow pipe 7. Specifically, a vertical partition 41 is provided in the rain gutter 4, which divides the rain gutter 4 into a drain chamber 42 and an overflow chamber 43. The bottoms of the drain chamber 42 and the overflow chamber 43 are connected and connected to the top of the drainage riser 5.
[0029] In addition, in this embodiment, the drain pipe 6 and the overflow pipe 7 have similar structures and can be assembled using finished components.
[0030] The drain pipe 6 comprises a first embedded pipe 61, a first curved pipe 62, and a first vertical pipe 63. The first embedded pipe 61 is embedded within the parapet 2 and is arranged at an angle. The higher end of the first embedded pipe 61 serves as the water inlet for the drain pipe 6 and connects to the inner side of the parapet 2, while the lower end of the first embedded pipe 61 connects to the outer side of the parapet 2. One end of the first curved pipe 62 connects to the lower end of the first embedded pipe 61, and the other end of the first curved pipe 62 bends downward and connects to the top of the first vertical pipe 63. The bottom end of the first vertical pipe 63 serves as the water outlet for the drain pipe 6, which extends into the drainage chamber 42.
[0031] The overflow pipe 7 comprises a second pre-buried pipe 71, a second curved pipe 72, and a second vertical pipe 73. The second pre-buried pipe 71 is pre-buried within the parapet 2 and is arranged at an angle. The higher end of the second pre-buried pipe 71 serves as the water inlet of the overflow pipe 7 and connects to the inner side of the parapet 2, while the lower end of the second pre-buried pipe 71 connects to the outer side of the parapet 2. One end of the second curved pipe 72 connects to the lower end of the second pre-buried pipe 71, and the other end of the second curved pipe 72 bends downward and connects to the top of the second vertical pipe 73. The bottom end of the second vertical pipe 73 serves as the water outlet of the overflow pipe 7, which extends into the overflow chamber 43.
[0032] The water inlet of drain pipe 6 is arranged on rainwater grate 9, is used to filter the foreign matter in the rainwater. The water inlet of drain pipe 6 is lower than the water inlet of overflow pipe 7, and the water outlet of drain pipe 6 is also lower than the water outlet of overflow pipe 7.
[0033] In this embodiment, a base plate 8, a plurality of first vertical plates 81, and a plurality of second vertical plates 83 are also pre-buried within the parapet 2. The base plate 8 is arranged horizontally and connected to the top of the roof 1. The drainage pipe 6 is connected to the base plate 8 via the plurality of first vertical plates 81, and the overflow pipe 7 is connected to the base plate 8 via the plurality of second vertical plates 83.
[0034] When pre-embedding the drain pipe 6 and overflow pipe 7, first connect the base plate 8, first riser 81, second riser 83, drain pipe 6, and overflow pipe 7, and then pre-embed the entire assembly within the parapet 2. During pre-embedding, secure the base plate 8 to the top of the roof 1 to position the drain pipe 6 and overflow pipe 7, ensuring they are installed at the correct angle and position, and enabling standardized on-site installation.
[0035] In addition, a plurality of first through holes 82 are provided on the first vertical plate 81, and a plurality of second through holes 84 are provided on the second vertical plate 83, so as to ensure stable flow of cement during pre-embedding.
[0036] In this embodiment, a drain pipe 6 and an overflow pipe 7 are provided. When the drain pipe 6 is blocked or water accumulates on the roof 1 during extreme rainstorms, water can be automatically discharged through the overflow pipe 7, thereby avoiding threats to building safety caused by deep water accumulation.
[0037] Preferably, Figure 4 As shown, a gutter 31 is provided at the top of the roof surface layer 3 near the parapet 2. The bottom of the water inlet of the drain pipe 6 is flush with the top of the roof surface layer 3, that is, flush with the bottom of the gutter 31. The bottom of the water inlet of the overflow pipe 7 is lower than the top of the gutter 31, so that accumulated water can be drained in time before it overflows the gutter 31, further improving the safety of the building.
[0038] In addition, this embodiment also realizes the regularization and unification of drainage and overflow of the roof 1 by connecting the drainage pipe 6 and the overflow pipe 7 to the rain gutter 4 and merging them into the drainage riser 5 so as to enter the site rainwater drainage system, reducing the number of drainage risers 5 and thus saving construction materials.
[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
