Abstract
Description
Technical Field
[0001] The present application relates to the technical field of window sill waterproofing, and in particular to an external window sill waterproofing structure. Background Art
[0002] The windowsill refers to the flat part that supports the window frame. In building construction, in order to prevent rainwater from seeping into the wall below the window, an external windowsill is usually installed outdoors. The external windowsill can drain the rainwater left along the window surface, preventing rainwater from seeping into the wall and causing erosion and damage to the wall.
[0003] In order to prevent rainwater from penetrating, existing external window sills are mostly tilted. The side of the window sill close to the external window is higher than the side away from the external window, so that the window sill surface has a certain downward slope. However, the usable area of the tilted surface is reduced and it is not stable. After long-term use, the sealing material may fall off and slide down the surface and hit pedestrians. The existing non-tilted window sills have poor drainage capacity, which makes it easy for rainwater to penetrate into the wall, causing cracks and other problems. This situation needs to be further improved. Utility Model Content
[0004] In view of the above technical problems, the present application provides an external window sill waterproof structure, which adopts the following technical solutions:
[0005] A waterproof structure for an external window sill includes a table top body, the table top body is arranged perpendicular to a wall, one end of the table top body is provided with a groove for embedding the bottom of a window frame, the table top body is provided with a waterproof groove near the groove, a plurality of guide grooves are arranged on the table top body, the guide grooves are connected with a drain outlet, a protective edge is arranged at the edge of the table top body, and the drain outlet passes through the protective edge arranged on the table top body away from the groove.
[0006] By adopting the above technical scheme, the table top body is arranged perpendicular to the wall without any inclination, so that the table top of the window sill remains flat. Compared with the table top arranged at an inclination, the usable area is larger, and green plants and other things can be placed to beautify the environment; a diversion groove is arranged on the table top body to divert rainwater so that rainwater can be discharged in time. The groove opened on the table top body is used to accommodate the window frame, and a waterproof groove is arranged near the groove. When the window frame and the table top body are installed, waterproof material can be filled in the waterproof groove, or waterproof strips can be attached; a protective edge is arranged on the edge of the table top body to play a protective role. When the wall or window sealing material falls off and falls onto the window sill, the protective edge can block it on the table top body.
[0007] Optionally, the guide groove tends to be inclined downward from an end close to the groove to an end away from the groove.
[0008] By adopting the above technical solution, the guide groove is arranged at an angle. When rainwater falls on the table body, the rainwater will first flow into the guide groove due to the effect of gravity, and continue to flow along the inclined direction of the guide groove. The guide groove is inclined downward from one end close to the groove to the direction away from the groove, making it easier for rainwater to be discharged from the drain outlet along the inclined direction of the guide groove, thereby reducing water seepage at the window frame installation location.
[0009] Optionally, a connecting groove is provided at one end of the table top body away from the groove, and the connecting groove connects all the guide grooves.
[0010] By adopting the above technical solution, the connecting groove connects all the diversion grooves together. When the drainage outlet connected to one of the diversion grooves is blocked, rainwater can flow from the connecting groove to other drainage outlets, making the rainwater diversion smoother.
[0011] Optionally, the guide groove and the connecting groove are both arc-shaped grooves.
[0012] By adopting the above technical solution, the arc-shaped groove has a better diversion effect compared with grooves of other shapes, and compared with grooves of other shapes, the arc-shaped groove has only one arc-shaped surface, which is not easy to hide dirt and is easier to clean.
[0013] Optionally, the depth of the connecting groove is smaller than the depth of the guide groove.
[0014] By adopting the above technical solution, the depth of the connecting groove is smaller than the depth of the guide groove, so that rainwater can flow from the connecting groove to the guide groove and then be discharged from the drain outlet without accumulating in the connecting groove.
[0015] Optionally, a backflow prevention plate is provided below a protective edge of the table top body on a side away from the groove.
[0016] By adopting the above technical solution, when rainwater is discharged from the drain outlet, most of the rainwater slides down along the outer surface of the protective edge, and the rainwater may flow back to the wall along the outer surface of the protective edge and the lower surface of the countertop body. The setting of the anti-backflow plate makes the rainwater slide down along the anti-backflow plate. The rainwater that slides to the bottom of the anti-backflow plate is difficult to flow from the anti-backflow plate to the lower surface of the countertop body under the action of gravity, thereby improving the waterproof effect.
[0017] Optionally, the bottom of the backflow prevention plate is in a rack shape.
[0018] By adopting the above technical solution, when rainwater slides from the anti-backflow plate to the bottom, the rainwater on each rack will condense along the edge of the rack to the tip of the rack. At the same time, it will take away the dust on the anti-backflow plate during the flow process, and finally drip at the tip of the rack. It has a stronger ability to condense rainwater and resist fouling, and can accelerate the dripping of rainwater.
[0019] Optionally, a water receiving trough is provided on the table body, the water receiving trough is connected to the drain outlet, and a water delivery port is provided on one side of the water receiving trough.
[0020] By adopting the above technical solution, a water receiving trough is arranged on the countertop body, and a water inlet is arranged on the water receiving trough, which can be connected with the drainage pipe. The water receiving trough can systematically collect the water discharged from all the drainage outlets, and then discharge it from the drainage pipe through the water inlet, thereby reducing the impact of rainwater dripping on the residents downstairs.
[0021] In summary, the present application includes at least one of the following beneficial technical effects:
[0022] 1. The table top is set perpendicular to the wall without any inclination, so that the window sill table top remains flat. Compared with the inclined table top, the usable area is larger, and green plants can be placed to beautify the environment; a diversion groove is set on the table top to divert rainwater so that rainwater can be discharged in time; a waterproof groove is set to fill waterproof materials, or waterproof strips are affixed to improve waterproof performance; a protective edge is set to play a protective role and improve safety;
[0023] 2. A backflow prevention plate is provided to prevent rainwater from flowing back. Furthermore, the bottom of the backflow prevention plate is provided in a rack shape to accelerate the dripping of rainwater;
[0024] 3. Set up a water trough to systematically collect and discharge the water discharged from the drain outlet to reduce the impact on residents downstairs. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following is combined with Figure 1-2 This application is described in further detail.
[0029] Example 1
[0030] The present application embodiment discloses an external window sill waterproof structure. Figure 1The outer window sill waterproof structure includes a table body 1, and a groove 2 is opened at one end of the table body 1. During installation, the window frame is embedded and installed in the groove 2. A waterproof groove 3 is provided near the groove 2 of the table body 1. After the window frame is installed, waterproof material can be filled in the waterproof groove 3 or a waterproof adhesive strip can be pasted to cover the gap between the window frame and the table body 1, and at the same time, a good waterproof effect can be achieved; different from the inclined setting of the existing table body 1, the table body 1 of this embodiment is arranged perpendicular to the wall, and a guide groove 4 is opened on the table body 1, and the guide groove 4 is connected to the drain port 5, so that rainwater is discharged through the guide groove 4, thereby maintaining the stability of the table, and can be used to place green plants and beautify the environment; in order to prevent the wall or window sealing material from sliding off the table and hitting pedestrians, a protective edge 6 is fixedly installed on the edge of the table body 1 to play a protective role, thereby improving safety.
[0031] In this embodiment, the table top body 1 is not tilted, but the guide groove 4 is tilted downward from one end close to the groove 2 to the end away from the groove 2, and the tilt angle is 5° to 10°. When rainwater falls on the table top body 1, under the action of gravity, the water first stays in the guide groove 4, and then flows to a lower place, and flows to the drain outlet 5 along the tilt direction of the guide groove 4 for discharge. The window frame is located in the direction of the highest point of the guide groove 4, so it is difficult for rainwater to flow to the window frame, reducing the water seepage at the window frame installation location.
[0032] Furthermore, a connecting groove 7 is provided at one end of the table body 1 away from the groove 2, and the connecting groove 7 connects all the guide grooves 4. Therefore, when the drain port 5 connected to one of the guide grooves 4 is blocked, rainwater can flow from the connecting groove 7 to other drain ports 5 for discharge, reducing the blockage of the channel and the occurrence of poor drainage, making the rainwater discharge smoother.
[0033] In this embodiment, the guide groove 4 and the connecting groove 7 are both configured as arc-shaped grooves 2. Compared with grooves 2 of other shapes, the arc-shaped groove 2 has only one arc surface, has a better guide effect, is less likely to hide dirt at the angle of the surface, and is easier to clean. Moreover, the depth of the connecting groove 7 is less than the depth of the guide groove 4, so that rainwater can flow from the connecting groove 7 to the guide groove 4, and then be discharged from the drain port 5, without accumulating in the connecting groove 7.
[0034] When rainwater is drained from the drain port 5, most of the rainwater slides down along the outer surface of the protective edge 6, and the rainwater may flow back to the wall along the outer surface of the protective edge 6 and the lower surface of the table body 1, causing water seepage in the wall, cracking, etc. In this regard, further, the present application provides an anti-backflow plate 8 below the protective edge 6 disposed on the side of the table body 1 away from the groove 2, so that the rainwater slides down along the anti-backflow plate 8, and the rainwater that slides to the bottom of the anti-backflow plate 8 is difficult to flow from the anti-backflow plate 8 to the lower surface of the table body 1 under the action of gravity, thereby achieving a better waterproof effect.
[0035] In this embodiment, the bottom of the backflow prevention plate 8 is in the shape of a rack. When rainwater slides down the backflow prevention plate 8 to the bottom, the rainwater on each rack will condense along the edge of the rack to the tip of the rack, and at the same time, it will take away the dust on the backflow prevention plate 8 during the flow process, and finally drip at the tip of the rack, which has a stronger ability to condense rainwater and resist contamination, and can accelerate the dripping of rainwater.
[0036] The implementation principle of an external window sill waterproof structure in Example 1 of the present application is as follows: a guide groove 4 is pre-opened on the window sill, a protective edge 6 and an anti-backflow plate 8 are cast, the window sill is installed on the window installation position reserved on the wall, and then the window frame is installed in the groove 2 of the table body 1. After the installation is completed, the waterproof groove 3 is filled with waterproof material, and fixed with waterproof glue. The drainage is carried out through the set guide groove 4, so that the table body 1 remains flat, and green plants can be placed to beautify the environment. At the same time, it has high safety. By setting waterproof materials and the diversion of the guide groove 4 and the anti-backflow plate 8, it is difficult for rainwater to penetrate into the wall, and the waterproof performance is good.
[0037] Example 2
[0038] The difference between the present embodiment and embodiment 1 is that: Figure 2 The embodiment of the present application does not have a backflow prevention plate 8. In this embodiment, a water receiving trough 9 is provided on the table body 1. The drainage ports 5 of all the guide troughs 4 are connected to the water receiving trough 9. A water delivery port 10 is provided on one side of the water receiving trough 9. When rainwater is discharged from the drainage port 5 along the guide trough 4, it first falls into the water receiving trough 9. The water receiving trough 9 systematically collects the rainwater and then discharges it through the water delivery port 10. In this embodiment, the water delivery port 10 can be connected to the drainage pipe of the building and discharged through the drainage pipe, thereby reducing the impact of rainwater dripping on the residents downstairs.
[0039] The implementation principle of Example 2 of the present application is as follows: a guide groove 4 is pre-opened on the windowsill, a protective edge 6 and an anti-backflow plate 8 are cast, the windowsill is installed on the window installation position reserved on the wall, and then the window frame is installed in the groove 2 of the table body 1. After the installation is completed, waterproof material is filled in the waterproof groove 3, and it is fixed with waterproof glue. The drainage is carried out through the set guide groove 4, so that the table body 1 remains flat, and green plants can be placed to beautify the environment. At the same time, it has high safety, and by setting waterproof materials and guide grooves 4, it is difficult for rainwater to penetrate into the wall, and the waterproof performance is good; by setting a water receiving trough 9, the water discharged from the drain outlet 5 is systematically collected and discharged, thereby reducing the impact on residents downstairs.
[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.
