Description

Technical Field

[0001] This application relates to the technical field of roofing projects, and in particular, to a waterproof and drainage structure for internal and external gutters on a tile roof. Background Art

[0002] Due to its unique structural design, the tile-pitched roof has good waterproof performance and durability, so it is widely used. The gutter is an important part of the roof drainage system. The existing gutters are directly fixed to the exterior wall of the house by concrete during installation, so that it is connected to the roof drainage system. The gutter collects the rainwater on the roof and guides it to the drainage pipe.

[0003] However, during the installation of the gutter in the above-mentioned manner, during rainy days, debris is likely to accumulate at the bottom of the gutter, resulting in poor water flow. As the rain volume increases, this blockage may cause an increase in water pressure, thereby increasing the risk of leakage. Therefore, in this case, the gutter will become a high-incidence area of leakage.

[0004] This leakage problem not only affects the waterproof performance of the roof, but may also damage the asphalt tiles, thereby affecting the durability and aesthetics of the entire roof. Summary of the Invention

[0005] In order to overcome the above technical problems, this application provides a waterproof and drainage structure for internal and external gutters on a tile roof.

[0006] A waterproof and drainage structure for internal and external gutters on a tile roof provided by this application adopts the following technical solutions:

[0007] A waterproof and drainage structure for internal and external gutters on a tile roof includes a tile roof, a flashing, and a gutter. Among them, the tile roof is installed on the roof, the flashing is installed at the lowest end of the tile roof, a connecting piece is provided between the gutter and the flashing, one end of the gutter is arranged at the bottom of the flashing, and the end of the gutter is fixed to the flashing through the connecting piece. The gutter is used to collect the rainwater on the tile roof. A downpipe and a waterproof layer structure are arranged at the bottom of the gutter. The downpipe is vertically installed and connected to the gutter. The waterproof layer structure is installed around the downpipe and is connected to the gutter. The waterproof layer structure provides connection and waterproofing.

[0008] By adopting the above technical solutions, with the cooperation of the flashing and the gutter, an efficient waterproof and drainage system is constructed. The tile roof, as the first layer in contact with the rainwater, enables the smooth drainage of the rainwater; the flashing is installed at the lowest end of the tile roof, effectively reducing the penetration of rainwater to the lower part of the roof; the gutter is tightly fixed to the flashing through the connecting piece, forming a stable rainwater collection structure. The downpipe and the waterproof layer structure further ensure the smooth discharge of rainwater and the waterproof performance of the system, not only improving the drainage efficiency of the roof, but also helping to enhance the waterproof ability of the overall structure.

[0009] Preferably, the gutter includes a connecting portion and a receiving portion. The cross-section of the receiving portion is in a "U" shape. The connecting portion is a plate-like structure. The connecting plate is inclined from the tile roof towards the inside of the receiving portion. The number of side walls of the connecting portion corresponds to that of the receiving portion, and the two are fixed by welding.

[0010] By adopting the above technical solution, the cooperation between the connecting portion and the receiving portion helps to efficiently drain and receive rainwater. The connecting portion is a plate-like structure and is inclined, which helps to guide the rainwater on the tile roof to smoothly flow into the receiving portion. The receiving portion provides sufficient capacity to hold rainwater, enhancing the stability and durability of the gutter to a certain extent and improving the rainwater collection efficiency.

[0011] Preferably, the flashing is arranged along the length of the tile roof.

[0012] By adopting the above technical solution, arranging the flashing along the length of the tile roof helps to enhance the waterproof effect at the edge of the roof, thus helping to reduce the later maintenance cost.

[0013] Preferably, the flashing is an integrally formed structure.

[0014] By adopting the above technical solution, the flashing is an integrally formed structure, greatly improving its structural strength and stability, enabling seamless connection between various parts of the flashing, reducing the leakage problem caused by loose joints. At the same time, it can enhance the anti-deformation ability of the flashing, enabling it to maintain stable waterproof performance under various environmental conditions.

[0015] Preferably, the flashing includes a connecting portion and a guiding portion. The connecting portion and the connecting portion of the gutter are parallelly distributed, and the two are fixed by the connecting piece. The guiding portion points towards the inside of the gutter.

[0016] By adopting the above technical solution, the flashing is composed of a connecting portion and a guiding portion, realizing more refined function division and structural optimization. The parallel distribution of the connecting portion and the connecting portion of the gutter and the fixing method through the connecting piece ensure a firm connection between the flashing and the gutter, effectively reducing the detachment or displacement caused by external forces. At the same time, the design that the guiding portion points towards the inside of the gutter can guide the rainwater to smoothly flow into the gutter, avoiding the accumulation or leakage of rainwater at the flashing, thus improving the efficiency and reliability of the entire drainage system.

[0017] Preferably, the gutter is arranged on the roof panel. The outer wall of the downpipe passes through the roof panel at the same time. The waterproof layer structure includes a reserved hole provided at the roof panel near the outer wall of the downpipe. The reserved hole is filled with slightly expanded concrete, and the gap between the reserved hole and the downpipe is filled and solidified by the slightly expanded concrete.

[0018] By adopting the above technical solution, the gutter is set on the roof panel, which enhances the stability of the overall structure. The outer wall of the downpipe passes through the roof panel to facilitate rainwater to quickly drain into the downpipe, reducing the possibility of water accumulation on the roof. In addition, the micro-expansion characteristics of concrete are utilized to fill the gap between the reserved hole and the downpipe, which effectively enhances the sealing of the connection and reduces rainwater leakage.

[0019] Preferably, the waterproof layer structure further includes a sealant, and the sealant is embedded between the micro-expansive concrete and the outer wall of the downpipe.

[0020] By adopting the above technical solution, the sealant is embedded in the gap between the micro-expansive concrete and the outer wall of the downpipe, forming an additional waterproof barrier. The sealant can adapt to the slight deformation of the concrete and the downpipe caused by temperature changes, maintain a continuous sealing state at the joint, thereby effectively resisting the intrusion of external moisture and helping to enhance the waterproof performance of the overall structure.

[0021] Preferably, a floor drain is installed on the top of the downpipe, and the waterproof layer structure also includes a waterproof pavement, which is laid on the inner bottom wall of the gutter, and its end extends between the floor drain and the downpipe, and the end of the waterproof pavement is reinforced by the deadweight of the floor drain and the friction between the floor drain and the downpipe.

[0022] By adopting the above technical scheme, the floor drain and the waterproof pavement work together to form a waterproof system on the top of the downpipe. The installation of the floor drain not only facilitates the rapid discharge of rainwater into the downpipe, but also reinforces the end of the waterproof pavement through its own weight and the friction with the downpipe, which not only achieves smooth drainage, but also effectively reduces rainwater leakage from the top of the downpipe. At the same time, the laying of the waterproof pavement further enhances the waterproof ability of the bottom wall of the gutter, providing double protection for the entire drainage system.

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

[0024] 1. The tile roof is the first surface that rainwater contacts, which allows for smooth drainage of rainwater. The flashing is installed at the lowest end of the tile roof to effectively reduce the penetration of rainwater under the roof. The gutter is tightly fixed to the flashing through the connector to form a stable rainwater collection structure. The downpipe and waterproof layer structure further ensure the smooth discharge of rainwater and the waterproof performance of the system, which not only improves the drainage efficiency of the roof, but also helps to enhance the waterproof ability of the overall structure.

[0025] 2. Arranging the flashing board along the length of the tile roof will help to enhance the waterproof effect of the roof edge, thus helping to reduce the subsequent maintenance costs;

[0026] 3. The flashing is composed of a connecting part and a diversion part, achieving a more refined functional division and structural optimization. The parallel distribution of the connecting part and the connection part and the fixing method through the connecting piece ensure a firm connection between the flashing and the gutter, effectively reducing the risk of detachment or displacement caused by external forces. At the same time, the design of the diversion part pointing towards the inside of the gutter can guide rainwater to flow smoothly into the gutter, preventing rainwater from accumulating or leaking at the flashing, thereby improving the efficiency and reliability of the entire drainage system.

Detailed Description of the Embodiment

[0031] The following will further describe the present application in detail Figures 1-3 in conjunction with the attached drawings.

[0032] The embodiment of the present application discloses a waterproof and drainage structure for internal and external gutters on a tile roof.

[0033] Referring to Figure 1 , a waterproof and drainage structure for internal and external gutters on a tile roof includes a tile roof 1, a flashing 2 and a gutter 3. Among them, the tile roof 1 is installed on the roof, the flashing 2 is installed at the lowest end of the tile roof 1, and a connecting piece 4 is provided between the gutter 3 and the flashing 2. In the present application, the structure of the connecting piece 4 is not limited, and countersunk screws can be selected here to make the material selection cheaper and more convenient. One end of the gutter 3 is arranged at the bottom of the flashing 2, and the end of the gutter 3 is fixed to the flashing 2 through the connecting piece 4. The gutter 3 is used to collect rainwater from the tile roof 1. A downspout 5 and a waterproof layer structure 6 are arranged at the bottom of the gutter 3. The downspout 5 is vertically installed and connected to the gutter 3, and the waterproof layer structure 6 is installed around the downspout 5 and connected to the gutter 3. The waterproof layer structure 6 provides connection and waterproofing.

[0034] During application, with the combined action of the flashing 2 and the gutter 3, an efficient waterproof and drainage system is constructed. The tile roof 1 serves as the first layer in contact with rainwater, facilitating the smooth drainage of rainwater. The flashing 2 is installed at the lowest end of the tile roof 1, effectively reducing the penetration of rainwater beneath the roof. The gutter 3 is tightly fixed to the flashing 2 through the connector 4, forming a stable rainwater collection structure. The downspout 5 and the waterproof layer structure 6 further ensure the smooth discharge of rainwater and the waterproof performance of the system.

[0035] Refer to Figure 2 and Figure 3 , specifically, the gutter 3 includes a connecting portion 31 and a receiving portion 32. The cross-section of the receiving portion 32 is in a "U" shape. The connecting portion 31 is a plate-like structure. The connecting plate is inclined from the tile roof 1 towards the inside of the receiving portion 32. The number of side walls of the connecting portion 31 corresponds to that of the connecting portion 31, and the two are fixed by welding. The connecting portion 31 is in a plate-like structure and is inclined, which helps to smoothly guide the rainwater on the tile roof 1 into the receiving portion 32. The receiving portion 32 provides sufficient capacity to hold rainwater.

[0036] More specifically, the flashing 2 is an integrally formed structure. The flashing 2 is selected as a plate body made of metal material. As a key waterproof barrier, its continuous and uninterrupted layout effectively reduces potential leakage points, making it have good corrosion resistance and durability, which helps to improve the waterproof reliability of the entire roof and plays a role in enhancing the waterproofing at the edge of the roof.

[0037] The flashing 2 includes a connecting portion 21 and a guiding portion 22. The connecting portion 21 is distributed in parallel with the connecting portion 31, and the two are fixed through the connector 4. The guiding portion 22 points towards the inside of the gutter 3. The parallel distribution of the connecting portion 21 and the connecting portion 31 and the fixing method through the connector 4 enable a firm connection between the flashing 2 and the gutter 3, effectively reducing the detachment or displacement caused by external forces. At the same time, the design that the guiding portion 22 points towards the inside of the gutter 3 can guide the rainwater to smoothly flow into the gutter 3, preventing the accumulation or leakage of rainwater at the flashing 2, thereby improving the efficiency and reliability of the entire drainage system.

[0038] The guiding portion 22 of the flashing 2 includes a first guiding area and a second guiding area. There is an arc transition between the first guiding area and the second guiding area. Moreover, the first guiding area is connected between the second guiding area and the connecting portion 21. The inclination angle of the first guiding area is greater than that of the second guiding area. With such a setting, the rainwater on the tile roof 1 can be quickly drained through the first guiding area, and the rainwater is buffered through the second guiding area before falling into the gutter 3, reducing the splashing of rainwater into the room during the rapid falling process.

[0039] Refer to Figure 2 and Figure 3, the gutter 3 is arranged on the roof panel 7, the outer wall of the downspout 5 passes through the roof panel 7 at the same time, the waterproof layer structure 6 includes a reserved hole 61 arranged at the outer wall of the downspout 5 near the roof panel 7, and a micro-expansion concrete 62 is embedded in the reserved hole 61. The gap between the reserved hole 61 and the downspout 5 is filled with the micro-expansion concrete 62. This application utilizes the micro-expansion characteristic of the concrete to fill the gap between the reserved hole 61 and the downspout 5, effectively enhancing the sealing performance of the connection and reducing the situation of rainwater leakage.

[0040] Meanwhile, the waterproof layer structure 6 further includes a sealant 63, and the sealant 63 is embedded between the micro-expansion concrete 62 and the outer wall of the downspout 5. The sealant 63 can adapt to the small deformations caused by temperature changes between the concrete and the downspout 5, maintaining the continuous sealed state of the connection, thereby effectively resisting the intrusion of external moisture and further enhancing the waterproof performance of the overall structure.

[0041] In this application, a floor drain 51 is installed at the top of the downspout 5, and the waterproof layer structure 6 further includes a waterproof pavement 64. The waterproof pavement 64 is laid on the inner bottom wall of the gutter 3, and its end extends between the floor drain 51 and the downspout 5. The end of the waterproof pavement 64 is reinforced by the self-weight of the floor drain 51 and the friction between the floor drain 51 and the downspout 5.

[0042] Under the combined action of the floor drain 51 and the waterproof pavement 64, they jointly constitute a waterproof system at the top of the downspout 5. The installation of the floor drain 51 not only facilitates the rapid drainage of rainwater into the downspout 5, but also reinforces the end of the waterproof pavement 64 through its self-weight and the friction with the downspout 5. It can not only achieve smooth drainage, but also effectively reduce the leakage of rainwater from the top of the downspout 5. At the same time, the laying of the waterproof pavement 64 further enhances the waterproof ability of the inner bottom wall of the gutter 3, providing double protection for the entire drainage system.

[0043] Refer to Figure 1 and Figure 2 , the methods of draining water in the inner gutter 3 and the outer gutter 3 in the drainage and waterproof structure of this application are roughly the same. The difference between the two is that when draining water in the inner gutter 3 of the drainage and waterproof structure, only one long side of the gutter 3 is assembled with the tile roof 1; when draining water in the outer gutter 3 of the drainage and waterproof structure, the two long sides of the gutter 3 are respectively assembled with two different tile roofs 1.

[0044] The above are all the preferred embodiments of this application. This embodiment is only an explanation of this application and does not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
