[0030] The present utility model provides a waterproof structure for a building roof, aiming to provide a drainage component and a support cushion layer, which can effectively prevent water from directly dripping on the roof, avoid roof ponding, and thus effectively improve the waterproof effect of the roof, and the excess water is discharged through the drainage component.

[0031] Please refer to Figures 1 to 5 , and the specific structure of the waterproof structure for a building roof proposed by the present utility model will be described in the following specific embodiments. In an embodiment of the present utility model, the waterproof structure for a building roof is installed on the roof and includes:

[0032] A planting layer 1, and the planting layer 1 is used to be arranged on the roof 20;

[0033] A drainage component 2, and the drainage component 2 is arranged on the side of the planting layer 1 facing the roof 20. The drainage component 2 is used to collect the excess water flowing out of the planting layer 1 and drain the water away; and

[0034] A support cushion layer 3, and the support cushion layer 3 is used to be installed on the roof 20 and is located between the drainage component 2 and the roof 20. The support cushion layer 3 is used to isolate the drainage component 2 from the roof 20.

[0035] In this embodiment, the building roof waterproof structure 10 includes a drainage component 2 and a support cushion layer 3. The support cushion layer 3 is installed on the roof 20, and the drainage component 2 is installed on the support cushion layer 3. Thus, the support cushion layer 3 can isolate between the drainage component 2 and the roof 20, preventing the drainage component 2 from directly contacting the roof 20. Once leakage occurs, when water seeps through the drainage component 2, it will drip onto the roof 20, forming ponding on the roof 20 and affecting the waterproof effect of the roof 20. Moreover, the support cushion layer 3 is fixed on the roof 20, making the entire roof 20 waterproof paving structure have good strength and being not easily deformed during long-term use, so as to ensure that the plants in the planting layer 1 grow well and stably.

[0036] Specifically, it further includes a planting layer 1, and the planting layer 1 is arranged on the side of the drainage component 2 away from the support cushion layer 3, facilitating people to plant plants on the planting layer 1, etc. Thus, while improving the greening effect of the roof 20, it also improves the waterproof effect of the roof 20. Then, when excess water can enter the drainage component 2 through the planting layer 1 and be drained away through the drainage component 2, and it ensures that the vegetation grows well and stably and plays a good greening effect.

[0037] Please refer to Figure 2 and Figure 3 In an optional embodiment, the drainage component 2 includes a housing 21, a first filter element 22, and a drain pipe 223. The support cushion layer 3 is installed at the bottom of the housing 21. The housing 21 forms a receiving cavity 211 with an opening. The first filter element 22 is arranged in the receiving cavity 211 to divide the receiving cavity 211 into a filtering cavity 2a and a drainage cavity 2b. The filtering cavity 2a is arranged on the side close to the planting layer 1, and the drain pipe 223 is communicated with the bottom wall of the drainage cavity 2b. The drain pipe 223 is used to drain the water in the drainage cavity 2b to the outside, preventing rainwater from staying on the roof 20 for a long time, causing excessive waterproof pressure on the roof 20, and effectively reducing the phenomenon of roof 20 seepage.

[0038] In this embodiment, the drainage component 2 includes a housing 21, a first filter element 22, and a drain pipe 223. Among them, the support cushion layer 3 is installed at the bottom of the housing 21, and the housing 21 forms a receiving cavity 211 with an opening. The first filter element 22 is installed in the receiving cavity 211 to divide the receiving cavity 211 into a filtering cavity 2a and a drainage cavity 2b. The filtering cavity 2a is arranged on the side close to the planting layer 1, and the drainage cavity 2b is arranged on the side close to the support cushion layer 3. Then, when the water discharged from the planting layer 1 will first enter the filtering cavity 2a, and after being filtered by the first filter element 22, it enters the drainage cavity 2b, and finally is discharged to the outside through the drain pipe 223. Thus, it effectively prevents excess water from accumulating on the roof 20, effectively improves the problem of ponding on the roof 20, and ensures the waterproof effect of the roof 20.

[0039] Please refer to Figure 3 , in an alternative embodiment, the first filter member 22 includes a plate body 221 and a filter channel 222 provided on the plate body 221. The plate body 221 is installed in the accommodation cavity 211, and the filter channel 222 penetrates through the plate body 221 to communicate the filter cavity 2a and the drainage cavity 2b. A filter screen 222a is provided at one end of the filter channel 222 facing the drainage cavity 2b. Thus, through the first filter member 22, deposits can be effectively intercepted, preventing the deposits from flowing with the water to the drain pipe 223, which may cause the drain pipe 223 to be blocked and the water stored on the roof 20 unable to be discharged.

[0040] In this embodiment, the first filter member 22 includes a plate body 221 and a filter channel 222 provided on the plate body 221. The plate body 221 is installed in the accommodation cavity 211, and the filter channel 222 penetrates through the plate body 221 to connect the filter cavity 2a and the drainage cavity 2b, facilitating the filtered water to smoothly pass through the filter channel 222 and drain into the drainage cavity 2b. Moreover, a filter screen 222a is provided at one end of the filter channel 222 facing the drainage cavity 2b, which can intercept the objects entrained in the water, ensuring that the water entering the drainage cavity 2b is free of debris and effectively preventing the drain pipe 223 from being blocked by debris. It should be noted that both ends of the filter channel 222 have openings for water to flow through, and the filter screen 222a can be installed on the filter channel 222 by welding or other means.

[0041] Please refer to Figure 2 and Figure 3 , in an alternative embodiment, a plurality of the filter channels 222 are provided. The plurality of filter channels 222 are arranged at intervals on the plate body 221. By providing a plurality of filter channels 222, the filtration of water can be further improved, ensuring that the first filter member 22 can smoothly filter the water.

[0042] In this embodiment, a plurality of filter channels 222 are provided, and the plurality of filter channels 222 are arranged at intervals on the plate body 221. When water enters the filter cavity 2a, it can be filtered through the plurality of filter channels 222, and under the action of the plurality of filter channels 222, the water can smoothly pass through the filtration of the filter channels 222 and enter the drainage cavity 2b.

[0043] Please refer to Figure 3 , in an alternative embodiment, the cross-section of each of the filter channels 222 is circular, and the cross-sectional area of each of the filter channels 222 gradually decreases from the end in the filter cavity 2a towards the end in the drainage cavity 2b, facilitating the filtration of debris by the filter channels 222.

[0044] Please refer to Figure 4, In an alternative embodiment, the support cushion layer 3 is formed with a receiving groove 31 for receiving the housing 21. The bottom wall of the receiving groove 31 is provided with a water guide groove 311 having an opening. A plurality of the water guide grooves 311 are provided, and the plurality of water guide grooves 311 are arranged at intervals on the bottom wall of the receiving groove 31. Thus, the water leaked from the housing 21 will directly enter the water guide groove 311 for storage, preventing the leaked water from seeping into the roof 20 and damaging the waterproof effect of the roof 20.

[0045] In this embodiment, in order to facilitate the collection of the water leaked from the drainage assembly 2, a receiving groove 31 for receiving the housing 21 is formed in the support cushion layer 3. Thus, the entire drainage assembly 2 is installed in the receiving groove 31, and a water guide groove 311 having an opening is provided in the bottom wall of the receiving groove 31. Once the drainage assembly 2 leaks water, the water will directly gather in the water guide groove 311, thereby preventing water droplets from falling on the roof 20 and causing water accumulation on the roof 20. It should be noted that one end of the drain pipe 223 passes through the support cushion layer 3 and communicates with the drainage cavity 2b.

[0046] Specifically, in order to facilitate the further collection of water, a plurality of water guide grooves 311 are provided, and the plurality of water guide grooves 311 are arranged at intervals on the bottom wall of the receiving groove 31. Thus, by providing a plurality of water guide grooves 311, the dripping water can be effectively collected and stored, preventing the leaked water from staying on the roof 20 for a long time, causing excessive waterproof pressure and effectively reducing the water seepage phenomenon of the roof 20. In this embodiment, four water guide grooves 311 are provided.

[0047] Please refer to Figure 1 and Figure 5 , In an alternative embodiment, the building roof waterproof structure 10 further includes a water storage assembly 4. The water storage assembly 4 is disposed between the planting layer 1 and the drainage assembly 2. One side of the water storage assembly 4 communicates with the planting layer 1, and the other side of the water storage assembly 4 communicates with the drainage assembly 2, so that the water storage assembly 4 stores the water flowing out of the planting layer 1, discharges the excess water to the housing 21, enables the roots of the vegetation to be in a moist environment, enables the vegetation to absorb sufficient water, maintains the good and stable growth of the vegetation, and can avoid frequent watering of the vegetation.

[0048] In this embodiment, in order to facilitate the storage of the water flowing out of the planting layer 1, a water storage assembly 4 is further included. The water storage assembly 4 is disposed between the planting layer 1 and the drainage assembly 2 and is separately connected to the planting layer 1 and the drainage assembly 2. Thus, the water storage assembly 4 can collect the excess water flowing out of the planting layer 1. When the water collected in the water storage assembly 4 is sufficient, the excess water will flow to the drainage assembly 2 and be discharged in time through the drainage assembly 2.

[0049] Please refer to Figure 5, In an alternative embodiment, the water storage structure includes a water storage bin 41 and a drainage pipe 42. The water storage bin 41 has an open cavity 411. An overflow port 412 is formed on the cavity wall of the cavity 411 near the opening. One end of the drainage pipe 42 communicates with the overflow port 412, and the other end of the drainage pipe 42 communicates with the filtration cavity 2a. Thus, the water in the water storage assembly 4 can flow through the drainage pipe 42 to the drainage assembly 2, and the excess water can be drained away through the drainage assembly 2.

[0050] In this embodiment, the water storage structure includes a water storage bin 41 and a drainage pipe 42. The water storage bin 41 has an open cavity 411. An overflow port 412 is formed on the cavity wall of the cavity 411 near the opening. One end of the drainage pipe 42 communicates with the overflow port 412, and the other end of the drainage pipe 42 communicates with the filtration cavity 2a. Thus, when the water in the water storage bin 41 reaches a certain level, it will drain out from the overflow port 412. Since the overflow port 412 is provided on the cavity wall of the cavity 411 and on one side of the opening, the water entering the water storage bin 41 will first settle down for preliminary filtration to prevent more impurities from entering the drainage assembly 2. When the water storage bin 41 continues to receive water, the water will flow from the overflow port 412 and the drainage pipe 42 to the drainage assembly 2.

[0051] Specifically, the water storage structure further includes a second filter element 43. The second filter element 43 is installed on the cavity wall of the cavity 411 and communicates with the overflow port 412. Thus, the water in the water storage bin 41 is filtered by the second filter element 43 after precipitation to reduce the impurities entering the drainage assembly 2. It should be noted that the second filter element 43 is a common filter screen, and this application will not elaborate on it here.

[0052] The above are only the preferred embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present utility model.
