[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] like Figure 1-3As shown, a waterproof structure combining a parapet and a roof comprises a roof wall 1 provided with a parapet 11, and also comprises an inclined sealing strip 2 with an inclined depression, and a guide groove 21 for drainage is opened on the center line of the inclined sealing strip 2;

[0025] A plurality of guide holes 22 are formed in the guide groove 21 , and lower row holes 221 communicating with the guide holes 22 are formed on the roof wall 1 .

[0026] Specifically, the parapet 11 and the roof wall 1 are both existing technologies and will not be elaborated here. The oblique sealing strip 2 can be made of rubber or cast with cement, and the cross-section of the oblique sealing strip 2 is an isosceles right triangle, and the hypotenuse end surface of the right triangle is recessed toward its diagonal side, and the two right-angled sides of the right triangle are respectively connected to the parapet 11 and the roof wall 1 and are waterproof and sealed.

[0027] By fixing the oblique seal strip 2 between the parapet 11 and the roof wall 1, a basic waterproof function is achieved, and the oblique surface of the oblique seal strip 2 can actively drain rainwater away from the edge of the roof wall 1, avoiding long-term water accumulation and erosion of the angle between the parapet 11 and the roof wall 1, and the guide groove 21 on the center line of the oblique seal strip 2 can drain rainwater from the oblique surface downward, and make the rainwater drain down through the guide hole 22, further reducing the infiltration caused by the gathering of rainwater on the roof wall 1, and the rainwater in the guide hole 22 can be quickly discharged away from the parapet 11 under the action of multiple lower discharge holes 221, further reducing the gathering of rainwater to avoid the problem of infiltration erosion, so as to increase the stability and durability of the parapet 11.

[0028] As an embodiment further provided by the present invention, a pipe 23 connected to the guide hole 22 is provided in the lower row hole 221 .

[0029] Specifically, the pipe 23 is a hard wear-resistant plastic pipe, and the plastic pipe is embedded in the oblique seal 2 made of cement by casting or bonded to the oblique seal 2 made of rubber by waterproof glue, and then the pipe 23 is inserted into the lower row hole 221.

[0030] The inclined pipe 23 can quickly drain rainwater on the center line of the inclined seal 2, and the rainwater entering the pipe 23 can directly bypass the angle between the inclined seal 2 and the parapet 11 and the roof wall 1, so that the rainwater will not penetrate between the three, thereby achieving a better waterproof effect between the roof wall 1 and the parapet 11.

[0031] As another embodiment further provided by the present invention, an upper sealing strip 24 and a lower sealing strip 240 are respectively provided at both ends of the oblique sealing strip 2, and are respectively connected to the parapet 11 and the roof wall 1.

[0032] Specifically, the upper sealing strip 24 and the lower sealing strip 240 are both rubber strips and are of the same length as the oblique sealing strip 2. The lower end of the upper sealing strip 24 fixedly connected to the side wall of the parapet 11 is fixedly installed on the oblique edge of the oblique sealing strip 2 by means of waterproof adhesive or screws; and the upper end of the lower sealing strip 240 fixedly connected to the top of the roof wall 1 is inserted into the hole opened on the oblique edge of the oblique sealing strip 2, and is fixedly installed in the hole by means of adhesive or screws.

[0033] By adopting different installation methods of the upper sealing strip 24 and the lower sealing strip 240 at the upper and lower ends of the inclined edge of the inclined sealing strip 2, the waterproof effect of the inclined sealing strip 2 is further enhanced, and the harm and risk of rainwater infiltrating between the roof wall 1 and the parapet 11 are reduced.

[0034] As another embodiment further provided by the present invention, a waterproof strip 241 is fixedly installed on the lower sealing strip 240 to abut against the end of the oblique sealing strip 2 .

[0035] Specifically, the waterproof strip 241 and the lower sealing strip 240 are of the same length, and the waterproof strip 241 is made of a waterproof material, which is a prior art and will not be described in detail here.

[0036] By setting the waterproof strip 241 to block the gaps between the upper and lower ends of the oblique seal strip 2 and the parapet 11 and the roof wall 1 respectively, the waterproof effect of the oblique seal strip 2 is further enhanced, greatly avoiding the possibility of rainwater seeping into the parapet 11 and the roof wall 1.

[0037] As another embodiment further provided by the present invention, a filter screen 242 covering the port of the guide groove 21 is fixedly installed between the upper sealing strip 24 and the lower sealing strip 240 .

[0038] Specifically, the filter screen 242 is a corrosion-resistant metal screen coated with a waterproof coating, which is used to isolate dirt from clogging the guide groove 21 and the guide hole 22.

[0039] By setting the filter 242, the dirt on the roof can be intercepted by the filter 242, so that the guide hole 22 will not be blocked by the dirt, the guide groove 21 can also flow water normally, and the pipe 23 can drain water more smoothly. In the later stage, it is only necessary to remove the dirt accumulated on the surface of the filter 242.

[0040] As another embodiment further provided by the present invention, a pressing block 243 is fixedly installed at the end of the filter screen 242 and abuts against the end of the lower sealing strip 240 .

[0041] When too much dirt accumulates on the filter screen 242, the gravity generated by the dirt causes the filter screen 242 to move closer to the guide groove 21. At the same time, the squeezing blocks 243 at both ends of the filter screen 242 are deformed, so that the deformed blocks 243 can additionally increase the sealing of the end of the lower sealing strip 240, further ensuring the effect of waterproofing.

[0042] As another embodiment further provided by the present invention, the pressing block 243 is specifically a rubber block.

[0043] The rubber pressing block 243 having the same length as the lower sealing strip 240 is more easily deformed by being squeezed and has a better sealing effect after deformation, so as to ensure that the waterproof structure can still maintain good waterproof function even in heavy rain and strong wind.

[0044] As another embodiment further provided by the present invention, a cover edge 25 facing the roof wall 1 is fixedly installed at the end of the guide groove 21, and a seepage channel 251 is formed between the cover edge 25 and the oblique sealing strip 2.

[0045] Specifically, the cover edge 25 is made of the same material as the oblique seal strip 2. If the oblique seal strip 2 is made of rubber, a mounting steel plate will be embedded inside the cover edge 25 to keep the cover edge 25 in an arc shape.

[0046] Furthermore, a depression is provided on the surface of the oblique sealing strip 2 at the obliquely downward position of the end of the guide groove 21, and the shielding edge 25 is located above the depression.

[0047] By intercepting the closure edge 25 at the end of the guide groove 21, the dirt filtered by the filter screen 242 can be further blocked, and the rainwater can flow downward along the closure edge 25 until it reaches the lower end of the seepage channel 251, so that the water containing a small amount of dirt can flow upstream and settle in the seepage channel 251, so as to ensure that the water entering the pipeline 23 will not be blocked by dirt.

[0048] As another embodiment further provided by the present invention, a plurality of protrusions 252 are fixedly mounted on the edge covering 25 and are interlaced and matched with the filter screen 242 .

[0049] Specifically, the diameter of the protrusion 252 is smaller than the diameter of the holes of the filter screen 242 , so that the protrusion 252 can dredge the holes of the filter screen 242 easily.

[0050] The gravity generated by the dirt makes the filter 242 move closer to the guide groove 21 and gradually fit the cover edge 25, so that the multiple protrusions 252 can clear the dirt when inserted into the holes of the filter 242, so that the dirt in the holes of the filter 242 can be actively washed away by rainwater, thereby ensuring the long-term use effect of the filter 242.

[0051] Working principle: The basic waterproof function is achieved by fixing the inclined seal 2 between the parapet 11 and the roof wall 1, and the inclined surface of the inclined seal 2 can actively drain rainwater away from the edge of the roof wall 1, avoiding long-term accumulation of water and erosion of the angle between the parapet 11 and the roof wall 1, and the guide groove 21 on the center line of the inclined seal 2 can drain rainwater from the inclined surface downward, and make the rainwater drain down through the guide hole 22, further reducing the infiltration caused by the gathering of rainwater on the roof wall 1, and the rainwater in the guide hole 22 can be quickly discharged away from the parapet 11 under the action of multiple lower discharge holes 221, further reducing the gathering of rainwater to avoid the problem of infiltration erosion.

[0052] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
