DETAILED DESCRIPTION

[0023] like Figures 1 to 6 As shown, a novel roof structure with rainwater collection function comprises a first roof, a second roof 10 and a storage device 6, wherein the second roof 10 is arranged above the storage device 6, and the first roof is arranged below the storage device 6. The storage device 6 is prevented from being eroded by the external environment, and the service life is extended. The storage device 6 is light in material and has large gaps, and after absorbing the external temperature in winter, it has a heat preservation effect.

[0024] The upper surface of the storage device 6 is provided with a storage module waterproof layer 11 that matches the second roof 10, and the lower surface of the storage device 6 is provided with a storage module waterproof layer 11 that matches the first roof. The storage module waterproof layer 11 adopts a HDPE waterproof layer. The shape of the storage device 6 is consistent with the shape of the roof. The storage device 6 is set to a flat structure with a height of 400mm, and a temporary support 7 is welded inside to ensure that the storage device 6 will not deform when the modules are spliced. After the roof is covered by the storage device 6, the storage device 6 can also be insulated to reduce the temperature inside the building.

[0025] The second roof 10 is provided with a rainwater filtering bucket 9 connected to the storage device 6. The lower end of the storage device 6 is connected to the drain pipe 5 through the outlet pipe 4. The outlet pipe 4 is provided with a switch valve 3. The upper end of the storage device 6 is connected to the drain pipe 5 through the overflow pipe 2. When the water level in the storage device 6 exceeds the storage limit, the excess rainwater flows out of the overflow pipe 2 into the drain pipe 5 for discharge, thereby preventing the water on the roof from being unable to be discharged.

[0026] A drainage groove 14 is provided on the upper surface of the second roof 10, and the drainage groove 14 is connected to the water inlet 8 on the second roof 10. A rainwater filtering bucket 9 cooperating with the storage device 6 is provided in the water inlet 8. The purpose of the drainage groove 14 is to quickly collect rainwater, reduce the residence time of rainwater on the second roof 10, and reduce the anti-seepage pressure of the waterproof layer of the second roof 10.

[0027] The filtering rainwater gutter 9 comprises a rainwater gutter body 901 and a filter cover 902 , wherein the filter cover 902 is arranged inside the rainwater gutter body 901 .

[0028] The inner wall of the rain gutter body 901 is provided with a limit pressing block 903 that cooperates with the filter cover 902, and a tightening screw 904 is rotatably provided inside the limit pressing block 903, and the tightening screw 904 is threadedly engaged with the screw sleeve 905. The design of the limit pressing block 903 prevents the filter cover 902 from being floated by rainwater in the storage device 6 and affecting the filtering effect, and the easy-to-remove structure of the limit pressing block 903 also enables the filter cover 902 to be quickly cleaned or replaced.

[0029] The first roof comprises a first roof waterproof protection layer 1 , a first roof waterproof layer 13 and a first roof structural layer 12 . The first roof waterproof layer 13 is arranged above the first roof structural layer 12 , and the first roof waterproof protection layer 1 is arranged above the first roof waterproof layer 13 .

[0030] The storage device 6 is a PP module storage device, which is covered with two layers of HDPE waterproof layer, and the gap between the device and the parapet is filled with modified asphalt sealant. The corresponding structural layer is formed on the storage module waterproof layer 11 to form the second roof 10. The first roof waterproof layer 13 is set between the first roof and the storage device 6. The first roof waterproof layer 13 uses two layers of modified asphalt plus self-adhesive waterproof layer, and the thickness of the first roof waterproof protective layer 1 is 100mm. Avoid the first roof waterproof layer 13 from being broken due to excessive pressure of the storage device 6.

[0031] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
