Description

Technical Field

[0001] The utility model relates to the technical field of roof waterproofing, in particular to a building roof waterproofing structure. Background Art

[0002] The roof, as the covering structure on top of the building, will accumulate a lot of water under climatic conditions such as rain and snow. In order to ensure that this accumulated water does not penetrate into the building, causing the roof to leak and thus affecting the living experience of residents, waterproofing measures are usually implemented on the roof. These measures are designed to effectively prevent accumulated water from passing through the roof structure, ensuring the integrity of the building and the comfort of the residents.

[0003] A roof waterproof structure is disclosed in a Chinese utility model patent with publication number CN217079421U, including a roof and a wall arranged around the roof, the wall including a first wall and a second wall arranged opposite to each other, a waterproof layer and a guide layer are stacked from bottom to top on the top surface of the roof, a first drainage structure for discharging accumulated water from the roof is arranged on the top surface of the roof, the guide layer is used to guide the accumulated water into the first drainage structure, a second guide groove is arranged on at least one side of the waterproof layer close to the first wall and a side of the waterproof layer close to the second wall, the second guide groove extends along the length direction of the first wall, the top surface of the waterproof layer is a guide surface, the guide surface is used to guide the accumulated water on the waterproof layer to the second guide groove, and the second guide groove is provided with a second drainage structure for discharging accumulated water.

[0004] Regarding the above-mentioned related technologies, the inventor believes that there are the following defects: the utility model does not have a filtering system at the outlet of the drainage pipe. Since dust in the external environment and scattered catkins may fall on the roof with the wind, especially on rainy days, these accumulated dust and catkins may clog the sewer pipe. This phenomenon will directly affect the drainage performance of the waterproof structure. If rainwater cannot be discharged in time, it may cause rainwater to leak into the wall, which will have an adverse impact on the living experience of the residents and may shorten the service life of the house. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a building roof waterproof structure.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a building roof waterproof structure, including a wall top, the top of the wall top is provided with a waterproof component for preventing rainwater from penetrating into the building, the waterproof component includes a waterproof coiled material, a waterproof layer and a flat top layer arranged in sequence from bottom to top, drainage ditches are opened all around the top of the wall body, drainage outlets are symmetrically opened at the bottom of the drainage ditch, filter plates are arranged on the top of the drainage ditch, a filter mesh body is arranged at a position near the drainage outlet in the drainage ditch, the top of the filter mesh body is in an upwardly protruding hemispherical shape, and a drainage pipe is connected to the side wall of the wall top at a position corresponding to the drainage outlet.

[0007] By adopting the above technical scheme, the wall top serves as the load-bearing and supporting structure of the roof, and the waterproof components form a solid waterproof barrier, which can effectively resist the invasion of external rainwater. When encountering climatic conditions such as rain and snow, the accumulated water on the roof surface will be filtered for the first time through the filter screen, which reduces the probability that the dust and catkins and other debris usually accumulated on the roof will flow to the drain ditch with the water flow and then block the drain pipe. Drain outlets are symmetrically opened at the bottom of the drain ditch to quickly discharge the accumulated water, and the filter body further filters the debris. The hemispherical structure of the filter body expands the filtration area to a certain extent, enhances the filtration effect, and fully reduces the probability of clogging the drain pipe, which is beneficial to improving the service life of the house and the living experience of the residents.

[0008] Furthermore, the height of the spherical center of the filter body is greater than the height of the bottom wall of the drainage ditch.

[0009] By adopting the above technical solution, when encountering heavy rain, even if there are debris flowing towards the drain outlet with the water flow, because the height of the center of the filter mesh body is greater than the height of the bottom wall of the drainage ditch, the filter mesh body can maintain a good filtering effect, which is beneficial for the drainage pipe to maintain a good water outlet effect.

[0010] Furthermore, the longitudinal section of the filter body is in an "Ω" shape, and expansion screws for fixing the filter body to the bottom wall of the drainage ditch are provided through the bottom of the filter body near its edge, and a downwardly concave annular recess is provided at the bottom of the filter body.

[0011] By adopting the above technical solution, the "Ω" shape helps to maintain the stability of the filter and reduces the probability of deformation during use. It is fixed by expansion screws to ensure the long-term stability of the filter body. The downwardly concave annular recess serves to contain and collect debris, which is beneficial for maintenance personnel to quickly clean up the debris collected in the annular recess at a later time.

[0012] Furthermore, a plurality of leakage holes are provided through the annular recessed portion.

[0013] By adopting the above technical solution and setting the leakage hole, when the maintenance personnel lift the filter mesh body and clean the debris collected in the annular recessed part, it is ensured that the accumulated water can be smoothly discharged from the annular recessed part.

[0014] Furthermore, the inner bottom wall of the drainage ditch is provided with a receiving groove matched with the edge of the filter screen body, and the edge of the filter screen body is fixedly sleeved with an annular rubber ring, and the outer wall of the annular rubber ring is tightly pressed against the inner wall of the receiving groove.

[0015] By adopting the above technical solution, the annular rubber ring enhances the tightness between the filter body and the bottom wall of the drain ditch, and reduces the probability of debris entering the drain pipe through the gap between the filter body and the drain ditch.

[0016] Furthermore, the inner bottom wall of the drainage ditch is arranged obliquely, and the height of the inner bottom wall of the drainage ditch close to the center of the wall top is greater than the height of the inner bottom wall of the drainage ditch close to the drainage outlet.

[0017] By adopting the above technical solution, the drainage ditch can quickly guide the accumulated water to the drainage outlet, thereby improving the drainage speed.

[0018] Furthermore, a slide groove connected to the side walls and bottom wall of the drainage ditch is provided on the top of the wall, and a reinforced filter screen is slidably connected to the inner wall of the slide groove, and the mesh diameter of the reinforced filter screen is smaller than the mesh diameter of the filter plate.

[0019] By adopting the above technical solution and reinforcing the setting of the filter screen, the water flow seeping from the filter screen plate is further filtered, and the probability of clogging of the filter screen body is reduced to a certain extent.

[0020] Furthermore, a handle is fixedly provided on the top of the filter body.

[0021] By adopting the above technical solution, it is convenient for workers to install and disassemble the filter body.

[0022] In summary, the utility model has the following beneficial effects:

[0023] 1. In this application, the wall top serves as the load-bearing and supporting structure of the roof, and the waterproof components form a solid waterproof barrier to effectively resist the invasion of external rainwater. Under climatic conditions such as rain and snow, the accumulated water on the roof surface will be filtered for the first time through the filter screen, which prevents the dust and catkins and other debris that usually accumulate on the roof from flowing to the gutter with the water flow and then clogging the gutter pipe. Drainage ports are symmetrically opened at the bottom of the gutter to quickly discharge the accumulated water, and the filter body further filters the debris. The hemispherical structure of the filter body expands the contact area to a certain extent, and the filtering effect is better, ensuring that the accumulated water will flow from the wall top into the gutter pipe at a faster flow rate, thereby avoiding the accumulation of water on the roof, which is conducive to improving the service life of the house and the living experience of the residents;

[0024] 2. In this application, when encountering heavy rain, even if there are debris flowing to the drain outlet with the water flow, because the height of the sphere center of the filter body is greater than the height of the bottom wall of the drainage ditch, it is avoided that the debris will block the filter body, further ensuring the practicality of the waterproof structure;

[0025] 3. In the present application, the "Ω" shape helps to maintain the stability of the filter and prevent it from deforming during use. It is fixed by expansion screws to ensure the long-term stability of the filter body. It is also convenient for cleaning and replacement of the filter body in the future. The downwardly concave annular recess serves to contain and collect debris. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0034] like Figure 1-6As shown, an embodiment of the present application discloses a building roof waterproof structure, including a wall top 1, a waterproof component 2, a drainage ditch 11, a filter plate 111, a filter mesh body 3 and a drainage pipe 13.

[0035] In the figure, only the structure of the wall top 1 is shown. In actual application, a parapet (not shown in the figure) is arranged at the top of the wall top 1 near the edge of the wall top 1.

[0036] The waterproof component 2 is arranged on the top of the wall top 1 and located in the parapet wall to prevent rainwater from penetrating into the building. The waterproof component 2 includes a waterproof coiled material 21, a waterproof layer 22 and a flat top layer 23 arranged in sequence from bottom to top.

[0037] The gutter 11 is arranged around the top of the wall, and its main function is to collect and discharge rainwater. The bottom of the gutter 11 is symmetrically provided with a drain port 12 so that the accumulated water can be discharged quickly.

[0038] The filter plate 111 is arranged on the top of the gutter 11 , and the accumulated water on the roof surface will be filtered for the first time through the filter plate 111 , thereby reducing the probability that the dust, catkins and other debris usually accumulated on the roof will flow to the gutter 11 with the water flow and then block the drain outlet 12 .

[0039] The filter mesh body 3 is arranged in the drainage ditch 11 near the drain outlet 12, and the top of the filter mesh body 3 is in an upwardly protruding hemispherical shape. The filter mesh body 3 further filters the debris, and the hemispherical structure of the filter mesh body 3 expands the filtering area to a certain extent, enhances the filtering effect, and fully reduces the probability of clogging of the drain pipe 13, which is conducive to improving the service life of the house and the living experience of the residents. The height of the ball center of the filter mesh body 3 is greater than the height of the inner bottom wall of the drainage ditch 11. When encountering heavy rain weather, even if there are debris flowing to the drain outlet 12 with the water flow, because the height of the ball center of the filter mesh body 3 is greater than the height of the inner bottom wall of the drainage ditch 11, the filter mesh body 3 can maintain a good filtering effect, which is conducive to the drainage pipe 13 maintaining a good water discharge effect. The longitudinal section of the filter mesh body 3 is in an "Ω" shape, and an expansion screw (not shown in the figure) for fixing the filter mesh body 3 on the inner bottom wall of the drainage ditch 11 is provided through the bottom of the filter mesh body 3 near its edge, and a downwardly concave annular recessed portion 31 is provided at the bottom of the filter mesh body 3. In this embodiment, the "Ω" shape helps maintain the stability of the filter screen and reduces the probability of deformation during use. The expansion screws are used to fix the filter screen body 3, ensuring the long-term stability of the filter screen body 3. The downwardly concave annular recess 31 plays a role in accommodating and collecting debris, which is conducive to maintenance personnel to quickly clean up the debris collected in the annular recess 31 in the later stage. A number of leak holes 311 are provided on the annular recess 31 to ensure that the accumulated water can be smoothly discharged from the annular recess 31 when the maintenance personnel lift the filter screen body 3 and clean up the debris collected in the annular recess 31.

[0040] The drainage pipe 13 is symmetrically arranged at a position on the side wall of the wall top 1 corresponding to the drainage port 12 , and is used to drain the accumulated water on the wall top 1 .

[0042] In order to quickly guide the accumulated water to the drain outlet 12 to increase the drainage speed, the inner bottom wall of the drain ditch 11 is inclined, and the height of the inner bottom wall of the drain ditch 11 close to the center of the wall top 1 is greater than the height of the inner bottom wall of the drain ditch 11 close to the drain outlet 12.

[0043] In order to further filter the water seeping from the filter plate 111, a slide groove 14 connected to the side wall and the bottom wall of the drainage ditch 11 is provided on the top of the wall, and a reinforced filter 15 is slidably connected to the inner wall of the slide groove 14. The mesh diameter of the reinforced filter 15 is smaller than the mesh diameter of the filter plate 111, which reduces the probability of blockage of the filter body 3 to a certain extent.

[0044] In order to facilitate the staff to install and disassemble the filter mesh body 3, a handle 34 is fixedly provided on the top of the filter mesh body 3.

[0045] The use principle of a building roof waterproof structure in the present embodiment is as follows: under climatic conditions such as rain and snow, the waterproof component 2 forms a solid waterproof barrier to effectively resist the invasion of external rainwater. The accumulated water on the roof surface will first be filtered through the filter screen 111, reducing the probability that dust, catkins and other debris usually accumulated on the roof will flow to the gutter 11 with the water flow and then block the drain pipe 13. The inner bottom wall of the gutter 11 is inclined, and the height of the inner bottom wall of the gutter 11 close to the center of the wall top 1 is greater than the height of the inner bottom wall of the gutter 11 close to the drain port 12, which helps the gutter 11 to quickly guide the accumulated water to the drain port 12, thereby increasing the drainage speed. The drain ports 12 are symmetrically provided at the bottom of the gutter 11 to quickly discharge the accumulated water. The filter screen body 3 further filters the debris. The hemispherical structure of the filter screen body 3 expands the filtration area to a certain extent, enhances the filtration effect, and fully reduces the probability of clogging the drain pipe 13. The filter mesh 3 has a spherical center height greater than the height of the bottom wall of the drainage ditch 11, so that the filter mesh 3 can maintain a good filtering effect, which is beneficial to the drainage pipe 13 to maintain a good water discharge effect, and is beneficial to improving the service life of the house and the living experience of the residents. The bottom of the filter mesh 3 is provided with a downwardly concave annular recessed portion 31 to accommodate and collect the debris, which is beneficial for the maintenance personnel to quickly clean up the debris collected by the annular recessed portion 31 in the later stage. A plurality of leakage holes 311 are penetrated on the annular recessed portion 31. When the maintenance personnel lift the filter mesh 3 and clean the debris collected by the annular recessed portion 31, it is ensured that the accumulated water can be smoothly discharged from the annular recessed portion 31. The edge of the filter mesh 3 is fixedly sleeved with an annular rubber ring 33 to enhance the tightness between the filter mesh 3 and the inner bottom wall of the drainage ditch 11, and reduce the probability of debris entering the drainage pipe 13 from the gap between the filter mesh 3 and the drainage ditch 11.
