Description

Technical Field

[0001] The present application relates to the technical field of building waterproof structures, and in particular to a waterproof structure for building roofs. Background Art

[0002] Architecture is a general term for buildings and structures. It is an artificial environment created by people in order to meet the needs of social life, using the material and technical means they have mastered and applying certain scientific laws and aesthetic principles. Waterproof structure is a measure taken in terms of building materials and structure to prevent water from penetrating certain parts of the building.

[0003] A Chinese patent with publication number CN214329610 discloses a roof waterproof structure, including a waterproof board fixedly connected to the roof and a connecting assembly for connecting adjacent waterproof boards. There are multiple waterproof boards, and the two ends of the connecting assembly are detachably connected to the sides of adjacent waterproof boards. Sealing pads are fixedly connected to the end surfaces of both sides of the waterproof board.

[0004] The structure has the function of connecting adjacent waterproof boards through a connecting component. The connecting component applies tension to the waterproof board material to splice the adjacent waterproof boards together. Under the action of the connecting component, the waterproof board squeezes the sealing gasket, which is deformed by the force. Finally, the sealing gasket seals the joints between the adjacent waterproof boards to reduce the infiltration of rainwater from the joints between the waterproof boards, thereby improving the waterproof effect of the waterproof board. However, with the long-term use of the waterproof board, the waterproof board will be partially damaged due to aging. At this time, the waterproof board will leak, and the waterproof effect will deteriorate, which is obviously insufficient. Utility Model Content

[0005] In order to alleviate the problem that the waterproof effect of the waterproof board deteriorates due to aging, the present application provides a waterproof structure for building roofs.

[0006] The present application provides a waterproof structure for building roofs using the following technical solutions:

[0007] A waterproof structure for building roofs, including a waterproof board, characterized in that a water storage box is provided below the waterproof board, a plurality of water inlet holes are opened on the surface of the water storage box, a fixing frame and a box body are provided on the water storage box, a rainproof component for blocking rainwater is provided in the box body, a reset component for pulling the rainproof component is provided in the fixing frame, and the reset component pulls the rainproof component to cover the top of the waterproof board.

[0008] By adopting the above technical solution, when the waterproof board leaks due to external factors, rainwater enters the water storage box through the water inlet hole. When the water level in the water storage box reaches a certain height, the reset component will pull the rainproof component to cover the surface of the waterproof board, thereby blocking the rainwater, thereby improving the waterproof effect of the waterproof board when leaking, and alleviating the problem of the waterproof effect of the waterproof board deteriorating due to aging.

[0009] Optionally, the rainproof component includes a winding roller rotatably connected to the inner wall of the box body, and a waterproof cloth is wound around the winding roller. When the waterproof cloth is unfolded by the reset component, the waterproof cloth covers and shields the waterproof board.

[0010] By adopting the above technical solution, in the initial state, the waterproof cloth is rolled up on the winding roller. When the water level in the water storage box reaches a certain height, the waterproof cloth will be unfolded on the surface of the waterproof board and cover the waterproof board. The waterproof effect of the waterproof board when leaking is improved by unfolding the waterproof cloth. At the same time, the setting of the waterproof cloth allows maintenance personnel to quickly and accurately locate the leaking waterproof board, which improves the inspection and maintenance efficiency and further ensures the waterproof effect when the waterproof board leaks.

[0011] Optionally, the reset component includes two moving blocks arranged at one end of the waterproof cloth, and the fixed frame is provided with sliding grooves corresponding to the moving blocks one by one. The moving blocks are slidably arranged in the sliding grooves, and springs are provided in the sliding grooves. One end of the spring is connected to the moving block, and the other end of the spring is connected to the inner wall of the sliding groove. When the waterproof cloth is rolled up on the winding roller, the spring is in a stretched state, and a fixing component for fixing the moving block is provided in the box body.

[0012] By adopting the above technical solution, in the initial state, the waterproof cloth is rolled up on the winding roller, and the spring is stretched through the fixing action of the fixing component. When the fixed state is released, the moving block moves along the slide groove in the direction away from the winding roller under the reset of the spring. At the same time, the moving block drives the waterproof cloth to unfold and cover the surface of the waterproof board, thereby blocking rainwater and ensuring the waterproof effect when the waterproof board leaks.

[0013] Optionally, a plurality of partitions are provided in the box body, and the fixed component includes a fixed block slidably arranged between two adjacent partitions, the fixed block and the movable block are arranged one-to-one correspondingly, a first magnetic sheet is provided on the fixed block, and a second magnetic sheet is provided on the movable block, and the first magnetic sheet and the second magnetic sheet are arranged opposite to each other and magnetically attracted to each other.

[0014] By adopting the above technical solution, when the waterproof effect of the waterproof board is stable, under the adsorption effect between the first magnetic sheet and the second magnetic sheet, the movable block is adsorbed and fixed on the end of the slide groove close to the winding roller, so that the spring is stretched and the winding state of the waterproof cloth is fixed; when the waterproof board leaks, the adsorption force between the first magnetic sheet and the second magnetic sheet gradually becomes smaller than the elastic force of the spring, and the waterproof cloth unfolds under the resetting action of the spring, thereby blocking the rainwater, thereby ensuring the waterproof effect when the waterproof board leaks.

[0015] Optionally, the water storage box is provided with a float corresponding to the fixed block one by one, the top surface of the float is provided with a connecting rod, the connecting rod is slidably set on the side wall of the water storage box, the connecting rod is provided with a top block, the fixed block is provided with a third magnetic sheet, the top block is provided with a fourth magnetic sheet, the third magnetic sheet and the fourth magnetic sheet are arranged opposite to each other and repel each other magnetically.

[0016] By adopting the above technical solution, when the waterproof board is broken or the waterproof effect becomes worse, rainwater will enter the water storage box from the water inlet hole. As the water level in the water storage box rises, the float drives the top block to move toward the fixed block. Under the repulsive force of the first magnetic sheet and the third magnetic sheet, the fixed block gradually moves upward. During the movement of the fixed block, the fixed block gradually becomes misaligned with the moving block, thereby gradually reducing the adsorption force between the first magnetic sheet and the second magnetic sheet. When the adsorption force is less than the elastic force of the spring reset, the spring resets and drives the waterproof cloth to unfold, thereby blocking the rainwater, thereby ensuring the waterproof effect when the waterproof board leaks.

[0017] Optionally, the water storage box is provided with a sleeve corresponding one-to-one to the connecting rod, the sleeve is connected to the box body, and the sleeve is slidably connected to the connecting rod.

[0018] By adopting the above technical solution, when the float rises with the water level, the top block will rise in the vertical direction under the restriction of the sleeve, ensuring the repulsive effect between the first magnetic sheet and the third magnetic sheet, reducing the possibility of failure to deploy the waterproof cloth, and thus ensuring the waterproof effect when the waterproof board leaks.

[0019] Optionally, a plurality of balls are provided on opposite surfaces of the partition.

[0020] By adopting the above technical solution, the provision of the balls can reduce the friction between the fixed block and the surface of the partition, making it easier for the fixed block to move vertically between the partitions.

[0021] Optionally, a mounting frame for mounting the waterproof board is provided above the water storage box, and waterproof strips are provided on the inner walls of the mounting frame in contact with the waterproof board.

[0022] By adopting the above technical solution, the waterproof strip can block the gap between the installation frame and the waterproof board, reducing the possibility of rainwater flowing along the gap to the water storage box, and avoiding the water level in the water storage box from rising when the waterproof board is not leaking, thereby ensuring the stability of the waterproof cloth when it is unfolded when the waterproof board is leaking.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The embodiment of the present application is provided with a rainproof component and a reset component. When the waterproof board leaks due to external factors, rainwater enters the water storage box through the water inlet hole and reaches a certain height. At this time, the reset component will pull the rainproof component to cover the side of the waterproof board in contact with the outside world, thereby blocking the rainwater and ensuring the waterproof effect when the waterproof board leaks.

[0025] 2. The embodiment of the present application sets a fixing component, a float and a top block, and fixes the rolled-up state of the waterproof cloth through the fixing component. The fixing effect of the fixing component on the resetting component is cancelled through the float and the top block, ensuring that the waterproof cloth is unfolded only when the waterproof board leaks.

[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] The embodiment of the present application discloses a waterproof structure for a building roof.

[0032] Reference Figure 1A waterproof structure for a building roof comprises an installation frame 1, a fixing frame 2, a water storage box 3 and a box body 4. The water storage box 3 is installed on the roof, the installation frame 1 and the box body 4 are installed above the box body 4, a waterproof board 11 is connected inside the installation frame 1, and waterproof strips 12 for shielding gaps are provided on the inner side walls around the installation frame 1 that are in contact with the waterproof board 11. The bottom surface of the waterproof board 11 is in close contact with the surface of the water storage box 3, and a fixing frame 2 is installed above the installation frame 1.

[0033] Reference Figure 1 and Figure 2 A rainproof component 5 and a fixing component 6 are provided in the box body 4, and a reset component 7 is provided in the fixing frame 2. When the waterproof effect of the waterproof board 11 is normal, the rainproof component 5 is fixed to one end of the fixing frame 2 through the fixing component 6. When the waterproof board 11 leaks due to external factors, under the action of the reset component 7, the rainproof component 5 will be unfolded along the length direction of the waterproof board 11 and cover the waterproof board 11, thereby blocking the rainwater, thereby ensuring the waterproof effect when the waterproof board 11 leaks.

[0034] Reference Figure 1 and Figure 2 The rainproof component 5 includes a winding roller 51 rotatably connected to the box body 4, and a waterproof cloth 52 that can block rainwater is wound on the winding roller 51. One end of the waterproof cloth 52 extends to the inner wall of the fixed frame 2. The reset component 7 includes two moving blocks 71 fixed to one end of the waterproof cloth 52. The two moving blocks 71 are distributed along a direction perpendicular to the unfolding direction of the waterproof cloth 52. The fixed frame 2 is provided with a slide groove 21 corresponding to the two moving blocks 71. The moving blocks 71 are slidably connected in the slide groove 21. The slide groove A spring 72 is connected to 21, one end of the spring 72 is connected to the moving block 71, and the other end of the spring 72 is connected to the inner wall of the slide 21 away from the winding roller 51. When the waterproof effect of the waterproof board 11 is normal, the moving block 71 is fixed to the end of the slide 21 close to the winding roller 51 through the fixing component 6. When the waterproof board 11 leaks, the spring 72 is reset. Under the reset action of the spring 72, the waterproof cloth 52 is unfolded along the surface of the waterproof board 11 and is tightly attached to the surface of the waterproof board 11.

[0035] Reference Figure 1 and Figure 2, a plurality of partitions 41 are installed in the box body 4. In the present embodiment, the number of the partitions 41 is four, and a plurality of balls 42 are installed on the relative surfaces of two adjacent partitions 41. The fixed assembly 6 includes a fixed block 61 which is slidably connected between the two adjacent partitions 41 and corresponds one to one with the moving block 71. In the fixed state, the fixed block 61 and the moving block 71 are on the same horizontal line, and a first magnetic sheet 62 is provided on a side of the fixed block 61 close to the moving block 71, and a second magnetic sheet 63 is provided on a side of the moving block 71 close to the fixed block 61. The first magnetic sheet 62 and the second magnetic sheet 63 are magnetically attracted to each other. When the centers of the first magnetic sheet 62 and the second magnetic sheet 63 are on the same horizontal line, the adsorption force of the first magnetic sheet 62 and the second magnetic sheet 63 is greater than the elastic force of the spring 72. When the waterproof effect of the waterproof board 11 is normal, the fixed block 61 adsorbs the second magnetic sheet 63 of the moving block 71 on the inner wall of the slide groove 21 through the first magnetic sheet 62. At this time, the waterproof cloth 52 is rolled up on the winding roller 51, and the spring 72 is stretched.

[0036] Reference Figure 2 and Figure 3 A plurality of water inlet holes 31 are provided on the surface of the water storage box 3 in contact with the waterproof plate 11. When the waterproof plate 11 leaks, rainwater flows into the water storage box 3 through the water inlet holes 31. A floating ball 32 corresponding to the fixed block 61 is provided in the water storage box 3. A connecting rod 33 is connected to the top surface of the floating ball 32. A sleeve 34 is sleeved on the outside of the connecting rod 33. The sleeve 34 is installed on the surface of the water storage box 3 and is connected to the box body 4. The opening of the sleeve 34 is located directly below the fixed block 61. A top block 35 is connected to the top of the connecting rod 33. The end of the fixed block 61 close to the top block 35 is connected to the third magnetic sheet 8. The end of the top block 35 close to the fixed block 61 is connected to the fourth magnetic sheet 9. The third magnetic sheet 8 and the fourth magnetic sheet 9 are magnetically repelled from each other. The repulsive force between the third magnetic sheet 8 and the fourth magnetic sheet 9 is greater than the attractive force between the first magnetic sheet 62 and the second magnetic sheet 63.

[0037] When the waterproof board 11 leaks, the float 32 floating in the water storage box 3 will rise with the rising water level. Under the limit of the sleeve 34, the top block 35 connected to the connecting rod 33 will move along the vertical direction toward the direction close to the fixed block 61. Under the repulsive force of the third magnetic piece 8 and the fourth magnetic piece 9, the fixed block 61 gradually moves upward between the balls 42. The setting of the balls 42 can reduce the resistance to the movement of the fixed block 61. During the movement of the fixed block 61, the fixed block 61 gradually becomes misaligned with the moving block 71, thereby gradually reducing the adsorption force between the first magnetic piece 62 and the second magnetic piece 63. When the adsorption force is less than the elastic force of the spring 72 to reset, the spring 72 resets and drives the waterproof cloth 52 to unfold, thereby blocking the rainwater, thereby ensuring the waterproof effect when the waterproof board 11 leaks.

[0038] Reference Figure 2 and Figure 3A water extraction port 36 and a sealing plug 37 for sealing the water extraction port 36 are provided on the surface of the water storage box 3. When the maintenance personnel come to the roof, they can accurately locate the waterproof board 11 that is leaking according to the unfolding of the waterproof cloth 52. After the maintenance of the waterproof board 11 is completed, the maintenance personnel pull out the sealing plug 37 and use the pumping equipment to extract the liquid in the water storage box 3 from the water extraction port 36. After the extraction is completed, the moving block 71 is manually moved back to the side of the winding roller 51 so that the first magnetic sheet 62 and the second magnetic sheet 63 are adsorbed on each other. At this time, the waterproof cloth 52 is rewound on the winding roller 51.

[0039] The implementation principle of a waterproof structure for a building roof according to an embodiment of the present application is as follows: when the waterproof board 11 leaks due to external factors, rainwater enters the water storage box 3 through the water inlet hole 31, and the float 32 in the water storage box 3 will drive the top block 35 to rise in the vertical direction as the water level rises. When the top block 35 gradually approaches the fixed block 61, the fixed block 61 rises along the ball 42 through the repulsive force between the third magnetic sheet 8 and the fourth magnetic sheet 9. After the fixed block 61 and the moving block 71 are gradually misaligned, the adsorption force between the first magnetic sheet 62 and the second magnetic sheet 63 gradually decreases. When the adsorption force is less than the elastic force of the spring 72, the spring 72 is reset. Under the action of the spring 72, the moving block 71 moves along the slide groove 21 and drives the waterproof cloth 52 to unfold, and finally the waterproof cloth 52 covers the surface of the waterproof board 11, thereby blocking the rainwater, thereby ensuring the waterproof effect when the waterproof board 11 leaks.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
