[0003] The roofs of modern buildings (high-rise buildings) are mainly flat. In extreme weather (such as heavy rain), a large amount of rainwater pours onto the ground of the roof. If the drainage structure of the roof does not drain water in time, a large amount of water will accumulate on the roof. The accumulated water will cause water seepage and damage the quality of the house. Therefore, a roof structure is needed to ensure smooth drainage of the roof. Utility Model Content
[0004] In order to ensure smooth roof drainage, the present application provides a roof drainage structure.
[0005] The present application provides a roof drainage structure, which adopts the following technical solution:
[0006] A roof drainage structure comprises a roof, a guard wall arranged on the roof and a drainage component arranged on the roof, wherein water guide grooves are provided at the four edges of the roof, and the groove walls of the water guide grooves are inclined downward in the direction away from the roof, and the drainage component comprises a floor drain, a connecting pipe and a drainage pipe, wherein the floor drain is installed at the bottom of the water guide groove, the drainage pipe is arranged at the edge of the roof, the connecting pipe connects the floor drain and the drainage pipe, and the floor drain is used to guide rainwater into the connecting pipe; a guide groove is provided on the ground of the roof, and the guide groove comprises a first guide groove and a second guide groove, and the extension directions of the first guide groove and the second guide groove are perpendicular to each other.

The rainwater in the water guide groove is partially accumulated and gradually discharged from the roof (building) to the ground through the drainage assembly composed of the floor drain, the connecting pipe and the drainage pipe. The arrangement of the first guide groove, the second guide groove and the water guide groove enables the rainwater on the top surface of the roof to be stably guided, which helps to stabilize the drainage. Even in the case of heavy precipitation, due to the stable drainage channel, the rainwater will not accumulate on the roof, the drainage is smooth, and the accumulated water is prevented from leaking into the building.

[0009] By adopting the above technical solution, an inclined chute is provided to facilitate the diversion of rainwater on the roof into the water guide chute.
[0010] Optionally, a plurality of water inlet grooves are provided on the side wall of the floor drain, and the plurality of water inlet grooves are arranged circumferentially along the floor drain, and the water inlet grooves are connected to the connecting pipe.
[0011] By adopting the above technical solution, a water inlet trough is provided to prevent large objects such as leaves and garbage from entering the drain pipe to prevent the drain pipe from being blocked.
[0012] Optionally, a slope groove is provided at the bottom of the water guide groove, four groove walls of the slope groove are inclined downward in a direction approaching each other, and the floor drain is arranged at the bottom of the slope groove.
[0013] By adopting the above technical solution, a slope groove is set to divert rainwater in the water guide groove, so that the rainwater is collected in the slope groove, which helps drainage.
[0014] Optionally, the bottom of the water inlet trough is flush with the bottom of the slope groove.
[0015] By adopting the above technical solution, the bottom of the water inlet trough is set flush with the bottom of the slope trough, so that rainwater can smoothly enter the floor drain and then be discharged through the connecting pipe and the drain pipe.
[0016] Optionally, an overflow hole is opened on the retaining wall, and the distance between the overflow hole and the bottom of the water guide groove is 3-5 cm.
[0017] By adopting the above technical solution, an overflow hole is set to assist drainage when the drainage of the roof is not smooth. Due to the existence of the retaining wall, water accumulates in the water guide groove. As the rainwater accumulates, the water level gradually rises to the overflow hole. When the water level is about to overflow the overflow hole, the accumulated water is discharged through the overflow hole (the overflow hole is set below the top surface of the roof) to prevent the accumulated water from overflowing to the top surface of the roof.

[0021] By adopting the above technical solution, a water dustpan is set to divert rainwater at the water outlet so that it flows smoothly to the top surface of the roof, preventing rainwater at the water outlet from directly washing to the top surface of the roof, thereby protecting the roof.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. When it rains, the rain falls on the roof, and the rain on the roof is guided into the water guide groove through the staggered first guide groove and the second guide groove. The rain in the water guide groove is partially accumulated and gradually discharged from the roof (building) to the ground through the drainage assembly composed of the floor drain, the connecting pipe and the drainage pipe. The first guide groove, the second guide groove and the water guide groove are arranged so that the rain on the roof top surface is stably guided, which is conducive to stable drainage. Even in the case of heavy precipitation, due to the stable drainage channel, the rain will not accumulate on the roof, the drainage is smooth, and the accumulated water is prevented from leaking into the building;
[0024] 2. Set up a water inlet trough to prevent large objects such as leaves and garbage from entering the drain pipe to prevent the drain pipe from being blocked;
[0025] 3. When the drainage of the roof is not smooth, the overflow hole is set to assist the drainage. Due to the existence of the retaining wall, the water accumulates in the water channel.
