Technical Field

[0001] This utility model relates to the field of green roof construction technology, specifically to a roof drainage structure for a green roof construction steel structure. Background Technology

[0002] In the field of green building, green roofs are becoming increasingly widely used due to their advantages such as beautifying the environment, reducing energy consumption, and providing ecological benefits. The steel roof drainage structure, as a key component ensuring the normal operation of green roofs, directly affects their performance and lifespan.

[0003] When building a green roof on a steel structure roof, traditional drainage methods are difficult to efficiently handle the large amount of rainwater generated by the green roof, which can easily lead to rainwater accumulation. Long-term accumulation of rainwater can not only affect the growth of green plants, but may also corrode the steel structure roof and reduce its service life. Utility Model Content

[0004] This utility model provides a roof drainage structure for green roof construction steel structure to solve the problems mentioned in the background art.

[0006] A green roof construction steel structure roof drainage structure includes a steel roof structure, the steel roof structure including a roof, and parapet walls are provided around the top of the roof; a drainage mechanism including a support member, a main drainage channel is provided on one side of the support member, and an installation groove is opened on the surface of the support member; and a support mechanism including a support plate, and an installation block that engages with the installation groove is provided at the bottom of the support plate.

[0007] A further improvement of the present invention is that the steel structure roofing mechanism further includes a raised walkway, which is located at the top of the roof.

[0008] A further improvement of this utility model is that the steel structure roofing mechanism also includes a green planting trough, and the surface of the green planting trough and the two sides of the raised walkway are provided with drainage outlets.

[0009] A further improvement of this utility model is that the green planting trough is set at the top of the roof, and the surface of the raised walkway is higher than the bottom of the inner cavity of the main drainage trough.

[0010] A further improvement of the present invention is that the drainage mechanism further includes an auxiliary drainage hole, which is disposed on the top of the support member.

[0011] A further improvement of the present invention is that: the support member is provided with an auxiliary drainage groove inside, and a confluence groove is provided at one end of the auxiliary drainage groove.

[0012] A further improvement of this utility model is that: a drain pipe is provided on one side of the inner cavity of the confluence channel, the bottom of the inner cavity of the auxiliary drainage channel is at the same level as the bottom of the inner cavity of the main drainage channel, and the interior of the auxiliary drainage channel is connected to the interior of the drain outlet.

[0013] A further improvement of the present invention is that the support mechanism further includes a planting pad, which is disposed on the top of the support plate.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0015] This utility model provides a roof drainage structure for green roof construction steel structures. Through the three-dimensional drainage network formed by the main drainage channel, auxiliary drainage holes and auxiliary drainage channels, when rainfall is low, rainwater permeates through the planting substrate and support plate, and is discharged along the main drainage channel under the guidance of the inclined surface of the support. When rainfall is heavy, the main drainage channel is filled with rainwater, and the rainwater overflows to the surface of the support and is drained through the auxiliary drainage channel. This allows the rainwater to flow along the auxiliary drainage pipe to the collection channel, improving the drainage effect. At the same time, the precise diversion design of the planting trough drainage outlet and the raised walkway can effectively cope with rainstorms, avoid the risk of water accumulation, and improve drainage efficiency.

[0022] The present invention will be further described in detail below with reference to embodiments:

[0023] Example 1

[0024] like Figure 1-5 As shown, this utility model provides a roof drainage structure for green roof construction using steel structure, including a steel roof structure mechanism, which includes a roof 11, with parapet walls 12 arranged around the top of the roof 11; a drainage mechanism, which includes a support member 21, with a main drainage channel 22 arranged on one side of the support member 21, and an installation groove 23 formed on the surface of the support member 21; and a support mechanism, which includes a support plate 31, with an installation block at the bottom of the support plate 31 that engages with the installation groove 23.

[0025] In this embodiment, after vegetation is planted in the green planting trough 13, excess water generated by rainfall or daily irrigation first falls on the surface of the roof 11. The parapet wall 12 around the roof plays a preliminary blocking role to prevent rainwater from overflowing. Subsequently, the water permeates through the planting pad material 32 and the support plate 31, and under the guidance of the inclined surface of the support member 21, it enters the main drainage trough 22, transports the water to the confluence trough 26, and then discharges it along the drainage pipe 28.

[0026] Example 2

[0027] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the steel structure roofing mechanism includes a roof 11, with parapet walls 12 arranged around the top of the roof 11; a drainage mechanism including a support member 21, with a main drainage channel 22 arranged on one side of the support member 21, and an installation groove 23 opened on the surface of the support member 21; a support mechanism including a support plate 31, with an installation block engaged with the installation groove 23 at the bottom of the support plate 31; the steel structure roofing mechanism also includes an elevated walkway 14, which is arranged on the top of the roof 11; the steel structure roofing mechanism also includes a green planting trough 13, with drainage outlets 15 arranged on the surface of the green planting trough 13 and on both sides of the elevated walkway 14; the green planting trough 13 is arranged on the top of the roof 11, and the surface of the elevated walkway 14 is higher than the bottom of the inner cavity of the main drainage channel 22; the drainage mechanism also includes an auxiliary drainage hole 24, which is arranged on the top of the support member 21.

[0028] In this embodiment, when there is a large amount of excess water, the main drainage channel fills with water and overflows to the surface of the support member 21. The auxiliary drainage hole 24 at the top of the support member 21 can guide the rainwater on the surface of the support member 21 to flow into the confluence channel 26 through the auxiliary drainage channel 25 inside the support member 21, and finally discharge it through the drain pipe 27. At the same time, the bottom of the inner cavity of the auxiliary drainage channel 25 is at the same level as the bottom of the inner cavity of the main drainage channel 22, ensuring that the auxiliary drainage system and the main drainage system can naturally converge and avoid water accumulation.

[0029] Example 3

[0030] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the steel structure roofing mechanism includes a roof 11, with parapet walls 12 arranged around the top of the roof 11; a drainage mechanism including a support member 21, with a main drainage channel 22 arranged on one side of the support member 21, and an installation groove 23 opened on the surface of the support member 21; a support mechanism including a support plate 31, with an installation block engaged with the installation groove 23 at the bottom of the support plate 31, an auxiliary drainage channel 25 arranged inside the support member 21, a confluence channel 26 arranged at one end of the auxiliary drainage channel 25, a drainage pipe 27 arranged on one side of the inner cavity of the confluence channel 26, the bottom of the inner cavity of the auxiliary drainage channel 25 being at the same level as the bottom of the inner cavity of the main drainage channel 22, the interior of the auxiliary drainage channel 25 communicating with the interior of the drainage outlet 15, and the support mechanism also including a planting pad 32, which is arranged on the top of the support plate 31.

[0031] In this embodiment, since the surface of the raised walkway 14 is higher than the bottom of the inner cavity of the main drainage trough 22, water falling onto the surface of the raised walkway 14 will flow into the auxiliary drainage trough 25 along the drain outlets on both sides, preventing water accumulation in the walkway area from affecting personnel passage. The bottom of the support plate 31 of the support mechanism is provided with an installation block that engages with the mounting groove 23 on the surface of the drainage mechanism support member 21. During construction and installation, the installation block of the support plate 31 can be directly embedded into the mounting groove 23 to achieve rapid assembly.

[0032] The working principle of the roof drainage structure of this green roof steel structure will be explained in detail below.

[0033] like Figure 1-5As shown, after vegetation is planted in the green planting trough 13, excess water from rainfall or daily irrigation first falls onto the surface of the roof 11. The parapet walls 12 around the roof provide initial protection against overflow. Subsequently, the water permeates through the planting mat 32 and the support plate 31, and under the guidance of the inclined surface of the support member 21, it enters the main drainage trough 22, transporting the water to the confluence trough 26, and then discharges along the drainage pipe 28. When the excess water volume is large, the main drainage trough fills up with water, and the water overflows onto the surface of the support member 21. The auxiliary drainage hole 24 at the top of the support member 21 guides the rainwater on the surface of the support member 21 through the auxiliary drainage trough 25 inside the support member 21 to the confluence trough. The water is discharged through the drain pipe 27. At the same time, the bottom of the inner cavity of the auxiliary drainage trough 25 is at the same level as the bottom of the inner cavity of the main drainage trough 22, ensuring that the auxiliary drainage system and the main drainage system can naturally converge and avoid water accumulation. Since the surface of the raised walkway 14 is higher than the bottom of the inner cavity of the main drainage trough 22, the water falling on the surface of the raised walkway 14 will flow into the auxiliary drainage trough 25 through the drain outlets on both sides, preventing water accumulation in the walkway area from affecting personnel passage. The bottom of the support plate 31 of the support mechanism is provided with an installation block that engages with the mounting groove 23 on the surface of the drainage mechanism support 21. During construction and installation, the installation block of the support plate 31 can be directly embedded into the mounting groove 23 to achieve rapid assembly.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
