[0002] Windows installed on exterior walls include window frames and glass windows. One side of the window frame is located outdoors and can be exposed to the sun and rain. The inner bottom wall of the window frame is generally a groove for the movement of the glass window, which easily accumulates rainwater. In order to prevent water from the window frame from entering the room, waterproofing of the exterior wall window frame is particularly important.

[0003] The utility model patent with the existing announcement number CN203213810U discloses a waterproof window frame, including a frame body, and inclined baffles are arranged on the frame edges around the frame body, the inclined baffles are seamlessly connected with the frame body to form a whole, and the length of the inclined baffles is 20mm-70mm. Since the inclined baffles are arranged on the frame edges around the frame body, the waterproofness of the window frame can be improved.

[0004] The above-mentioned prior art solutions have the following defects: the waterproofing of the above-mentioned window frame is mainly aimed at the outer periphery of the window frame and the wall, but does not consider the inner bottom wall of the window frame and the glass window. The inner bottom wall of the window frame is connected to the outside world, and rainwater on the inner bottom wall of the window frame may enter the room through the bottom gap of the glass window, and the waterproofing is insufficient. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a leakage waterproof structure for an exterior wall window frame, which can discharge water from the bottom wall of the window frame, prevent water from entering the room through the bottom gap of the glass window, and improve the waterproof performance.

[0006] The above technical purpose of the utility model is achieved through the following technical scheme: the leakage waterproof structure of the exterior wall window frame includes a window frame body, the window frame body is fixed with an outer peripheral plate for outdoor use, the inner bottom wall of the window frame body is provided with a leakage groove, and the top of the leakage groove is provided with a permeable concrete block.

[0007] Through the above technical solution, when it rains outdoors, water will enter the inner bottom wall of the window frame body. The water is on the top surface of the permeable concrete block. The permeable concrete block allows the water to penetrate downward due to its characteristics. After the water enters the drainage trough, it is discharged from the bottom of the drainage trough outside the window frame body.

[0008] Preferably, the drainage groove comprises an overhead groove located directly below the permeable concrete block and an inclined water guide groove connected to the outer side of the window frame body, and the bottom of the overhead groove is connected to the top of the inclined water guide groove.

[0009] Through the above technical solution, the overhead trough is connected to form a connected space under the permeable concrete block, so that the water that passes through the permeable concrete block can be collected in the overhead trough. The bottom end of the inclined water guide trough is located at the outer wall of the window frame body, and the inclined water guide trough is used to guide the rainwater collected in the overhead trough to the outside of the window frame body, and then discharge the rainwater.

[0010] Preferably, a plurality of pads are fixed to the inner bottom wall of the overhead trough, and the upper ends of the pads abut against the bottom surface of the permeable concrete block.

[0011] Through the above technical solution, the pad blocks play the role of raising the permeable concrete blocks and forming an overhead trough.

[0012] Preferably, the circumferential side walls of the pads do not contact the groove walls of the overhead grooves, and the pads are distributed at intervals along the length direction of the permeable concrete block.

[0013] Through the above technical solution, the obstruction of the cushion block to the water flow in the overhead trough can be reduced to the greatest extent.

[0014] Preferably, the outer plate is provided with a notch, the bottom edge of the notch is lower than the top surface of the permeable concrete block, and the outer plate is hingedly connected with a baffle at the notch, and the baffle blocks the notch.

[0015] Through the above technical solution, users can discharge the garbage swept from the top surface of the permeable concrete block through the gap, making cleaning more convenient. When not in use, the baffle can cover the gap by rotating.

[0016] Preferably, the notch is located at the end of the outer plate in the length direction, and the top end of the baffle is rotatably connected to a hinge shaft, and the hinge shaft is rotatably connected to the outer plate.

[0017] Through the above technical solution, the notch is set at the end of the outer plate in the length direction, which makes it easier to discharge the garbage on the top surface of the permeable concrete block. When the user uses a brush, cloth or other tools to sweep the garbage on the top surface of the permeable concrete block to the notch at the end of the outer plate, the garbage can be directly swept out of the top surface of the permeable concrete block through the notch, which makes it more convenient to use. The hinge shaft is set at the top of the baffle to prevent the garbage from hitting the hinge shaft when cleaning the garbage, so that the hinge shaft can be kept clean and the service life can be extended.

[0018] Preferably, a clamping block is fixed to the bottom end of the baffle, the clamping block is in the shape of a semi-cylinder, and the inner bottom wall of the notch is provided with a clamping groove having a shape corresponding to the clamping block.

[0019] Through the above technical solution, the baffle can be fixed by the clamping block and the clamping groove to prevent the baffle from rotating spontaneously.

[0020] Preferably, a water guide plate is fixed to the outer wall of the window frame body, the water guide plate is located below the bottom end of the inclined water guide groove, and the plate surface of the water guide plate extends downward in an inclined shape.

[0021] Through the above technical solution, the water guide plate is used to guide water outward at an angle, preventing water from flowing along the outer wall of the window frame body to the contact position with the wall, thereby preventing water from entering the joint between the window frame body and the wall.

[0022] In summary, the beneficial effects of the present invention compared with the prior art are as follows:

[0023] 1. Through the permeable concrete block and the drainage groove, the water on the bottom wall of the window frame can be drained to prevent water from entering the room from the bottom gap of the glass window, thus improving the waterproof performance;

[0024] 2. Since permeable concrete blocks have numerous micropores and uniform water seepage, there will be no blockage problem caused by traditional leaky structures;

[0025] 3. The garbage mixed in the water will be blocked on the top of the permeable concrete block, so the inclined water channel used for drainage later is not easy to be blocked, so it does not require frequent maintenance and cleaning, which is convenient for long-term use.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-4 The utility model is described in further detail.

[0032] Reference Figure 1 , is a leakage waterproof structure of an exterior wall window frame disclosed by the utility model, comprising a window frame body 1, to which an outer peripheral plate 2 for outdoor use is fixed, the outer peripheral plate 2 is located at the bottom edge of the window frame body 1, and the inner side of the outer peripheral plate 2 is the inner bottom wall of the window frame body 1.

[0033] Reference Figure 2 and Figure 3 The inner bottom wall of the window frame body 1 is provided with a drainage groove 3, and a permeable concrete block 4 is provided on the top of the drainage groove 3, and the drainage groove 3 is located below the permeable concrete block 4. It should be noted that the permeable concrete block 4 is installed after being prefabricated, rather than being cast in the window frame body 1, that is, the permeable concrete block 4 is cast in an external mold and solidified, and then installed in the window frame body 1 as a whole in a solid form. Permeable concrete is a prior art material, and the permeable concrete has a large number of micropores inside, which can guide rainwater to penetrate downward.

[0034] The drainage trough 3 includes an overhead trough 31 located directly below the permeable concrete block 4 and an inclined water guide trough 32 connected to the outside of the window frame body 1, and the bottom of the overhead trough 31 is connected to the top of the inclined water guide trough 32. The length direction of the overhead trough 31 is arranged along the length direction of the window frame body 1, and the overhead trough 31 is connected to form a connected space below the permeable concrete block 4, so that the water that passes through the permeable concrete block 4 can be collected in the overhead trough 31. The inclined water guide trough 32 is opened in a punching manner, and the top of the inclined water guide trough 32 is connected to the bottom wall of the overhead trough 31. The end of the inclined water guide trough 32 away from the overhead trough 31 is inclined downward, and the bottom end of the inclined water guide trough 32 is located at the outer wall of the window frame body 1. The inclined water guide trough 32 is used to guide the rainwater collected in the overhead trough 31 to the outside of the window frame body 1, and then discharge the rainwater. It should be noted that a plurality of inclined water guide troughs 32 are arranged at intervals along the length direction of the window frame body 1 to improve the drainage effect of the overhead trough 31.

[0035] A water guide plate 11 is fixed to the outer wall of the window frame body 1. The water guide plate 11 is located below the bottom end of the inclined water guide groove 32. The plate surface of the water guide plate 11 extends downward in an inclined shape. The water guide plate 11 is used to guide water outward obliquely to prevent water from flowing along the outer wall of the window frame body 1 to the contact position with the wall, thereby preventing water from entering the joint between the window frame body 1 and the wall.

[0036] A plurality of pads 12 are fixed to the inner bottom wall of the overhead groove 31, and the upper ends of the pads 12 abut against the bottom surface of the permeable concrete block 4. The pads 12 are located in the middle of the width direction of the overhead groove 31, and the circumferential side walls of the pads 12 do not contact the groove wall of the overhead groove 31. The pads 12 are spaced apart along the length direction of the permeable concrete block 4. The pads 12 may be cylindrical or rectangular. Since the circumferential side walls of the pads 12 do not contact the groove wall of the overhead groove 31, the pads 12 can avoid blocking the water in the overhead groove 31, making drainage more efficient. It should be noted that the permeable concrete block 4 is placed on the cushion block 12, the width of the permeable concrete block 4 is the same as the width of the overhead groove 31, the length of the permeable concrete block 4 is the same as the length of the overhead groove 31, and the permeable concrete block 4 will not shake in the overhead groove 31. At the same time, the structure allows personnel to remove the permeable concrete block 4 by moving it upward. After removing the permeable concrete block 4, on the one hand, it is convenient to install the cushion block 12, and on the other hand, it is convenient to clean the overhead groove 31.

[0037] The outer plate 2 is provided with a notch 21, the bottom edge of which is lower than the top surface of the permeable concrete block 4, and a baffle 22 is hingedly connected to the outer plate 2 at the notch 21, and the baffle 22 blocks the notch 21. After the user rotates the baffle 22 to open the notch 21, the garbage swept from the top surface of the permeable concrete block 4 can be discharged through the notch 21, making cleaning more convenient.

[0038] The notch 21 is located at the end of the outer plate 2 in the length direction, and the top of the baffle 22 is rotatably connected with a hinge shaft 23, and the hinge shaft 23 is rotatably connected to the outer plate 2. The notch 21 is arranged at the end of the outer plate 2 in the length direction, which makes it easier to discharge the garbage on the top surface of the permeable concrete block 4, because when the user cleans the top of the permeable concrete block 4, they sweep from one end to the other end, that is, when the user uses a brush, cloth or other tools to sweep the garbage on the top surface of the permeable concrete block 4 to the notch 21 at the end of the outer plate 2, the garbage can be directly swept out of the top surface of the permeable concrete block 4 through the notch 21, which is more convenient to use. The hinge shaft 23 is arranged at the top of the baffle 22, which can prevent the garbage from hitting the hinge shaft 23 when cleaning the garbage, and can keep the hinge shaft 23 clean and extend the service life.

[0039] Reference Figure 3 and Figure 4 A clamping block 24 is fixed at the bottom end of the baffle 22, and the shape of the clamping block 24 is a semi-cylindrical body. The inner bottom wall of the notch 21 is provided with a clamping groove 25 having a shape corresponding to the clamping block 24. The clamping block 24 and the clamping groove 25 can realize the clamping fixation of the baffle 22 to prevent the baffle 22 from rotating spontaneously; when the notch 21 needs to be used, the personnel can press the baffle 22 outward to disengage the clamping block 24 from the clamping groove 25, thereby rotating the baffle 22 to open the notch 21.

[0040] The implementation principle of the leakage waterproof structure of the exterior wall window frame is as follows: when it rains outdoors, water will enter the inner bottom wall of the window frame body 1, and the water will be on the top surface of the permeable concrete block 4. The permeable concrete block 4 allows the water to penetrate downward due to its characteristics. After the water enters the overhead groove 31, it will gather in the overhead groove 31, and then the water will be discharged from the window frame body 1 through the inclined water guide groove 32.

[0041] Through the leakage waterproof structure of the exterior wall window frame, the water on the inner bottom wall of the window frame body 1 can be discharged. Since the permeable concrete block 4 has countless micropores and uniform water seepage, there will be no problem of blockage caused by traditional leakage structures, and the garbage mixed in the water will also be blocked on the top of the permeable concrete block 4. Therefore, the inclined water guide trough 32 used for drainage later is not easy to be blocked, so it does not require frequent maintenance and cleaning, which is convenient for long-term use.

[0042] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
