Description

Technical Field

[0001] This application relates to the field of building construction, and in particular to a roof waterproof structure. Background Art

[0002] The roof is a building component at the top of the building, and its main function is to protect the top of the building.

[0003] Currently, the related art discloses a waterproof structure for a roof, which successively includes a floor base layer, a waterproof layer, a protective layer, and a decorative layer from bottom to top. A wall is installed on the peripheral side of the floor base layer, and a drainage groove is opened on the peripheral side of the floor base layer. A drain hole communicating with the drainage groove is opened on the wall. The top side of the decorative layer is inclined and gradually decreases from the middle to the periphery. When it rains, rainwater flows into the drainage groove through the guidance of the decorative layer, and then the rainwater is discharged from the drain hole, thereby reducing the situation that rainwater accumulates on the roof and seeps into the roof, and further improving the waterproof performance of the roof.

[0004] Regarding the above related art, the inventor believes that some people may carry out activities such as drying clothes, planting flowers and plants, and having meals on the roof. When activities are carried out on the roof, some garbage will fall on the roof and not be cleaned up. After that, the garbage may enter the drainage groove and block the drain hole. After the drain hole is blocked, if it rains, rainwater may accumulate on the roof. When the rainwater accumulates on the roof, it seeps into the roof, and the waterproof layer is easily damaged after being soaked by rainwater for a long time, thereby affecting the waterproof performance of the roof. Summary of the Invention

[0005] In order to improve the waterproof performance of the roof, this application provides a roof waterproof structure.

[0006] A roof waterproof structure provided by this application adopts the following technical solutions:

[0007] A roof waterproof structure includes a floor base layer and a wall installed on the peripheral side of the floor base layer. The wall is provided with a drain hole communicating with a first drainage groove. The top surface of the floor base layer is provided with a first drainage groove along the periphery. The top surface of the floor base layer is provided with a plurality of second drainage grooves. Both ends of the second drainage groove communicate with the first drainage groove. A waterproof layer, a protective layer, and a decorative layer are successively installed on the top surface of the floor base layer from bottom to top. The waterproof layer and the protective layer are attached to the inner walls of the first drainage groove and the second drainage groove. The decorative layer is provided with a water inlet gap communicating with the second drainage groove. The distance between the two inner side walls of the water inlet gap is smaller than the distance between the two inner side walls of the second drainage groove body. A shielding frame is fixedly installed along the periphery on the top surface of the decorative layer.

[0008] By adopting the above technical solution, when garbage falls onto the roof, the shielding frame shields the garbage, thereby reducing the occurrence of the drainage port being blocked after the garbage falls into the first drainage groove. Meanwhile, the water inlet gap blocks large-sized garbage, and at the same time, rainwater on the roof flows into the second drainage groove through the water inlet gap, and then the water is discharged from the second drainage groove into the first drainage groove. The water inside the first drainage groove is discharged from the drainage port, thus reducing the occurrence of rainwater accumulating on the roof, and further improving the waterproof performance of the roof.

[0009] Optionally, a first brush is arranged inside the second drainage groove, and a moving mechanism is installed on the first brush. The moving mechanism is used to drive the brush to move along the length direction of the second drainage groove to clean the inner wall of the second drainage groove.

[0010] By adopting the above technical solution, the moving mechanism drives the first brush to move inside the second drainage groove, and the first brush cleans the dust inside the second drainage groove, which is beneficial to keeping the inside of the second drainage groove clean. At the same time, the dust inside the second drainage groove is cleaned, thus reducing the occurrence of the situation where the dust accumulates inside the second drainage groove and hinders the rainwater from flowing from the second drainage groove into the first drainage groove, and further improving the waterproof performance of the roof.

[0011] Optionally, the inner bottom of each second drainage groove is inclined and gradually decreases from the middle to both ends.

[0012] By adopting the above technical solution, after the rainwater enters the second drainage groove, the rainwater is guided by the bottom of the second drainage groove and flows into the first discharge groove, which is beneficial to discharging the water inside the second drainage groove, and further reducing the residual amount of rainwater inside the second drainage groove. By reducing the residual amount of rainwater inside the second drainage groove, the situation where the rainwater seeps into the roof and damages the waterproof layer is reduced, and further the waterproof performance of the roof is improved.

[0013] Optionally, the moving mechanism includes a counterweight, a first pulley and a lifting rope. One side of the counterweight is fixedly connected to one side of the first brush, the first pulley is fixedly installed on the bottom side of the counterweight, and one end of the first lifting rope is fixedly connected to one side of the counterweight.

[0014] By adopting the above technical solution, pull the lifting rope, and the lifting rope drives the counterweight to move along the length direction of the second drainage groove to the middle of the second drainage groove. Then release the lifting rope, and the counterweight slides inside the second drainage groove under the influence of gravity, thus facilitating the cleaning of the inner wall of the second drainage groove.

[0015] Optionally, a second brush is disposed inside each of the second drain grooves. A fixed pulley is fixedly installed in the middle of the inner bottom wall of the second drain groove. The fixed pulley is located between the first brush and the second brush. A box body is fixedly installed on the side of the second brush away from the fixed pulley. A second pulley is fixedly installed on the bottom side of the box body. One end of the first suspension rope away from the counterweight is connected to the box body after passing around the fixed pulley.

[0016] By adopting the above technical solution, when it rains, rainwater drains into the box body through the water inlet gap, thereby increasing the weight of the box body. When the weight of the box body is greater than the weight of the counterweight, the box body drives the counterweight to move inside the second drain groove through the suspension rope, so that the first brush and the second brush automatically clean the inner wall of the second drain groove. After the rain stops, the water inside the box body gradually evaporates, or the water inside the box body is manually drained. Then the counterweight drives the box body to slide through the suspension rope, so that the first brush and the second brush clean the inner wall of the second drain groove again.

[0017] Optionally, a drain hole is opened on the side of the box body away from the fixed pulley, and a baffle is rotatably connected to the inner wall on the side of the box body away from the fixed pulley.

[0018] By adopting the above technical solution, when it is necessary to drain the water inside the box body, the baffle is turned over to open the drain hole, thereby facilitating the drainage of the water inside the box body. When it is necessary for the box body to accumulate rainwater, the baffle is turned over to let the baffle block the drain hole, thereby facilitating the box body to accumulate rainwater.

[0019] Optionally, a first attracting plate is fixedly installed on the inner bottom wall at one end of the second drain groove. The first attracting plate is located on the side of the box body away from the fixed pulley. A magnetic attraction rod is fixedly installed on the side of the first attracting plate close to the fixed pulley. The magnetic attraction rod is used to pass through the drain hole to jack up the baffle, and the magnetic attraction rod attracts the baffle.

[0020] By adopting the above technical solution, when the box body moves towards the first attracting plate, the magnetic attraction rod is inserted into the drain hole. The baffle is pushed by the magnetic attraction rod to open the drain hole, thereby realizing automatic drainage of the box body. When the rainfall is large, the box body automatically drains water, so that it is convenient for the first brush and the second brush to move back and forth inside the second drain groove for cleaning.

[0021] Optionally, a first magnet is fixedly installed on the side of the box body close to the first attracting plate. The first magnet is used to attract the first attracting plate.

[0022] By adopting the above technical solution, when the magnetic attraction rod needs to push the baffle to turn over and open the drain hole, the first magnet attracts the box body, thereby accelerating the moving speed of the box body towards the first attracting plate, and thus facilitating the magnetic attraction rod to push the baffle to turn over and open the drain hole.

[0023] Optionally, a second attracting plate is fixedly installed on the inner bottom wall at one end of the second drain trough. The second attracting plate is located on the side of the counterweight away from the fixed pulley. A second magnet is embedded on the side of the counterweight away from the fixed pulley, and the second magnet is used to attract the second attracting plate mutually.

[0024] By adopting the above technical solution, when the counterweight moves towards the second attracting plate, the counterweight attracts the second attracting plate mutually through the second magnet. After that, the weight of the accumulated rainwater in the box body needs to be greater than the weight of the counterweight and the magnetic force of mutual attraction between the second magnet and the second attracting plate, then the box body can pull the counterweight to move through the suspension rope, which is beneficial to improving the moving speed of the box body, and further improving the cleaning effect of the first brush and the second brush.

[0025] Optionally, the top surface of the decorative layer is inclined with the position where the water inlet gap is located as the lowest point.

[0026] By adopting the above technical solution, when rainwater falls on the decorative layer, the rainwater flows into the water inlet gap through the guiding of the inclined direction of the decorative layer, thereby reducing the occurrence of rainwater accumulating on the decorative layer.

[0027] To sum up, the present application includes at least one of the following beneficial technical effects:

[0028] When there is garbage falling on the roof surface, the shielding block shields the garbage from directly falling into the first drain trough. At the same time, when the volume of the garbage is larger than the water inlet gap, it cannot enter the second drain trough, thereby reducing the occurrence of the drain opening being blocked after the garbage enters the first drain trough and the second drain trough, and further facilitating the drainage of the water on the roof surface. By draining the rainwater on the roof surface in time, the situation that the waterproof layer is damaged after being soaked by the rainwater is reduced, and the waterproof performance is further improved.

Specific embodiments

[0039] The following further elaborates on this application in conjunction with the attached Figures 1-9 drawings for a more detailed description.

[0040] The embodiment of this application discloses a roof waterproof structure.

[0041] Referring to Figure 1 , Figure 2 , Figure 3 , a roof waterproof structure includes a floor base layer 1, a waterproof layer 2, a protective layer 3, and a decorative layer 4 that are connected in sequence from bottom to top.

[0042] Referring to Figure 1 , Figure 2 , an enclosure wall 5 is fixedly installed on the circumferential side of the floor base layer 1. A first drainage groove 6 is formed along the circumference on the top surface of the floor base layer 1, and a plurality of second drainage grooves 7 are also formed on the top surface of the floor base layer 1. Each second drainage groove 7 is parallel to each other. The waterproof layer 2 and the protective layer 3 are attached to the inner walls of the first drainage groove 6 and the second drainage grooves 7. The enclosure wall 5 is provided with a drain outlet 8 that communicates with the first drainage groove 6.

[0043] A shielding frame 9 is fixedly installed on the circumferential side of the top surface of the decorative layer 4, and a plurality of water inlet gaps 10 are formed on the top surface of the decorative layer 4. The water inlet gaps 10 correspond to the second drainage grooves 7 one by one, and the water inlet gaps 10 communicate with the second drainage grooves 7. The distance between the two inner side walls of the water inlet gap 10 is smaller than the distance between the two inner side walls of the second drainage groove 7 body.

[0044] When it rains, rainwater flows into the second drainage trough 7 from the water inlet gap 10 of the decorative layer 4. Then the water inside the second drainage trough 7 is discharged into the first drainage trough 6, and then discharged from the drainage outlet 8. The rainwater on the roof is discharged through the water inlet gap 10, the first drainage trough 6 and the second drainage trough 7, so as to reduce the accumulation of rainwater on the roof. By reducing the accumulation of rainwater on the roof, the amount of rainwater seeping into the roof is reduced, and further the situation of the waterproof layer 2 being damaged by rainwater immersion is reduced. By reducing the situation of the waterproof layer 2 being damaged by rainwater immersion, the waterproof performance of the roof is improved.

[0045] The shielding frame 9 shields garbage from entering the first drainage trough 6, and the water inlet gap 10 restricts large-volume garbage from entering the second drainage trough 7, so as to reduce the situation of the drainage outlet 8 being blocked by garbage, and further facilitate ensuring the drainage effect of the roof. By ensuring the drainage effect of the roof, the waterproof performance of the roof is improved.

[0046] Refer to Figure 4 , the top surface of the decorative layer 4 is inclined with the position where the water inlet gap 10 is located as the lowest point. Rainwater falls on the decorative layer 4 and flows into the water inlet gap 10 under the guidance of the inclined direction of the decorative layer 4, so as to facilitate the discharge of rainwater from the decorative layer 4, and further improve the waterproof performance of the roof.

[0047] Refer to Figure 5 、 Figure 6 , the inner bottom of the second drainage trough 7 is inclined gradually from the middle to both ends, and a first brush 11 and a second brush 12 are arranged inside the second drainage trough 7. A fixed pulley 13 is fixedly installed in the middle of the inner bottom wall of the second drainage trough 7. The fixed pulley 13 is located between the first brush 11 and the second brush 12.

[0048] Refer to Figure 7 、 Figure 8 , the first brush 11 is provided with a moving mechanism 14, and the moving mechanism 14 includes a counterweight 141, a first pulley 142 and a suspension rope 143. The counterweight 141 is fixedly installed on the side of the first brush 11 away from the fixed pulley 13, and one end of the suspension rope 143 is fixedly connected to the side of the counterweight 141 close to the fixed pulley 13. The first pulley 142 is installed on the bottom side of the counterweight 141. One end of the suspension rope 143 away from the counterweight 141 is fixedly installed with a box body 15, and the side of the box body 15 close to the suspension rope 143 is fixedly connected to the side of the second brush 12 away from the fixed pulley 13. The suspension rope 143 is wound around the fixed pulley 13. A second pulley 16 is installed on the bottom side of the box body 15.

[0049] Refer to Figure 8, a drain hole 17 is provided on the side of the box body 15 away from the fixed pulley 13, and a shielding plate 18 is rotatably connected to the inner wall on the side of the box body 15 away from the fixed pulley 13. When the shielding plate 18 is rotated, when the shielding plate 18 is rotated upward, the drain hole 17 is opened, so as to facilitate the box body 15 to drain water. When the shielding plate 18 is rotated downward and abuts against the inner wall of the box body 15, the drain hole 17 is closed, so as to facilitate the box body 15 to store water.

[0050] Refer to Figure 8 , Figure 9 , a first magnet 19 is embedded on the side of the box body 15 away from the second brush 12, and a first attracting plate 21 is fixedly installed on the inner bottom wall at one end of the second drain groove 7. The first attracting plate 21 is located on the side of the box body 15 away from the fixed pulley 13, and the first attracting plate 21 is used for the first magnet 19 to attract each other. A magnetic attracting rod 23 is fixedly installed on the side of the first attracting plate 21 close to the fixed pulley 13. The magnetic attracting rod 23 is used to pass through the drain hole 17 to lift the shielding plate 18, and the magnetic attracting rod 23 attracts the shielding plate 18.

[0051] Refer to Figure 7 , a second attracting plate 22 is fixedly installed on the inner bottom wall at one end of the second drain groove 7. The second attracting plate 22 is located on the side of the counterweight 141 away from the fixed pulley 13. A second magnet 20 is embedded on the side of the counterweight 141 away from the fixed pulley 13, and the second magnet 20 is used to attract the second attracting plate 22.

[0052] The implementation principle of a roof waterproof structure in an embodiment of the present application is as follows: when there is garbage falling on the roof, the shielding frame 9 shields the garbage from entering the first drain groove 6, and there is also garbage with a large volume that cannot enter the second drain groove 7 through the water inlet gap 10, thereby reducing the occurrence of the drain port 8 being blocked by garbage. By reducing the occurrence of the drain port 8 being blocked by garbage, it is convenient for the rainwater on the roof to be discharged in time, and further reduces the occurrence of the rainwater seeping into the roof and soaking the waterproof layer 2. By reducing the occurrence of the rainwater seeping into the roof and soaking the waterproof layer 2, it is beneficial to delay the aging of the waterproof layer 2, and further improves the waterproof performance of the roof.

[0053] Meanwhile, when it is raining, some rainwater drains into the interior of the box body 15 through the water inlet gap 10, thereby gradually increasing the weight of the box body 15. When the weight inside the box body 15 is greater than the weight of the counterweight 141 and the attraction between the counterweight 141 and the second attracting plate 22, the box body 15 drives the counterweight 141 to move towards the first attracting plate 21 through the suspension rope 143. When the box body 15 and the counterweight 141 move, the first brush 11 and the second brush 12 clean the inner wall of the second drainage groove 7, thereby scraping off the dust inside the second drainage groove 7. By cleaning the second drainage groove 7, the situation where dust accumulation hinders the rainwater inside the second drainage groove 7 from entering the first drainage groove 6 is reduced, and further the situation where rainwater seeps into the roof and damages the waterproof layer 2 is reduced. Meanwhile, the second attracting plate 22 attracts the second magnet 20, which is beneficial to accelerating the moving speed when the box body 15 drives the counterweight 141, thereby improving the cleaning effect of the first brush 11 and the second brush 12 on the inner wall of the second drainage groove 7.

[0054] When the box body 15 abuts against the first attracting plate 21, the first attracting plate 21 and the first magnet 19 attract each other, which facilitates the magnetic attraction rod 23 to push the shielding plate 18 to turn upwards. The shielding plate 18 turns upwards, thereby opening the drain hole 17, and the water inside the box body 15 drains out from the drain hole 17, and the weight of the box body 15 gradually decreases. When the weight of the box body 15 and the gravitational force between the first attracting plate 21 and the first magnet 19 are less than the weight of the counterweight 141, the counterweight 141 drives the box body 15 to move towards the second attracting plate 22 through the suspension rope 143, so that the first brush 11 and the second brush 12 clean the inner wall of the second groove body again. By automatically cleaning the inner wall of the second groove body with the first brush 11 and the second brush 12 on rainy days, the situation where dust accumulates inside the second groove body is reduced.

[0055] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
