[0026] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings. The illustrative implementation methods and descriptions of the embodiments of this disclosure are only used to explain the embodiments of this disclosure and are not intended to limit the embodiments of this disclosure.

[0027] like Figure 1 As shown, a waterproof substrate for building roofs according to this application includes a waterproof base layer 1, a drainage guide channel 2, a reinforcing support plate 3, a sealing layer 4, an inclined diversion plate 5, and a fixing fastener 6. The components work together to reduce the risk of water seepage accumulation.

[0028] The waterproof underlayer 1 of this substrate is a key component that comes into direct contact with the building roof. It is made of high-strength waterproof materials, such as modified bitumen or high-performance synthetic rubber. The waterproof underlayer 1 is evenly applied to the roof surface through a coating process to form a preliminary waterproof protective layer and ensure that the substrate is firmly attached to the building structure surface, effectively isolating the roof base layer from direct contact with external water flow.

[0029] Drainage guide channel 2 is located above the leak-proof base layer 1 and features a V-shaped structure design to enhance water flow guidance. The V-shaped structure of drainage guide channel 2 allows for natural flow when rainwater or seepage accumulates, guiding the water to the designated drainage area. To reduce clogging caused by impurity accumulation, tiny anti-clogging micropores 21 are provided on the surface (see details). Figure 4 These micropores have a diameter that can be controlled between 0.5 and 1 mm, which prevents larger particles from clogging the drainage system without significantly interfering with drainage performance. Furthermore, the bottom of the drainage guide channel 2 is designed with a hydrophobic texture 22 (see details). Figure 3 For example, cross-shaped lines can further reduce the risk of water seepage and improve drainage efficiency.

[0030] The reinforcing support plate 3 is connected to both sides of the drainage guide channel 2 to enhance the overall structural strength and prevent deformation or failure due to water flow impact or external loads during long-term use. Its manufacturing materials are typically lightweight high-strength alloy steel or fiberglass composite materials, ensuring both weight reduction and ideal support effect. The specific installation method can be a mechanical locking mechanism to tightly connect it to the drainage guide channel 2, while ensuring a smooth transition with the surrounding structure, thereby maintaining the integrity of the entire substrate.

[0031] The sealing layer 4 covers the opening of the drainage guide channel 2 to further prevent water from seeping into other directions from inside the drainage channel. It is typically made of a flexible and dense material, such as a thermosetting epoxy resin coating, and is applied evenly to the channel opening using a spraying or casting process. This structure effectively seals any possible seepage channels, providing reliable secondary protection, especially under conditions of high flow or heavy rain.

[0032] The inclined drainage plate 5 is located on one side of the top of the sealing layer 4 and is fixed to the sealing layer 4 by welding or bolting. Its inclined design can significantly accelerate the collection of water flow and accurately guide it into the drainage guide channel 2, preventing rainwater from spreading or stagnating on the surface. Depending on the actual situation, the drainage plate can be adjusted with different slopes and materials to adapt to different climatic conditions and environmental requirements. For example, the slope can be appropriately increased for rainy areas in the south, while materials with better anti-freezing properties can be selected for low-temperature environments in the north.

[0033] The fasteners 6 are evenly distributed around the perimeter of the waterproof base layer 1, mainly to ensure that the entire waterproof base material is stably attached to the roof structure. Each set of fasteners 6 includes metal bolts and corresponding crimping components, which are anchored by penetrating the roof panel or concrete base layer, ensuring that the waterproof base material can maintain a good attachment even in severe weather, thereby continuing to work and achieve its intended function.

[0034] Through the design and optimization of the above components, this application solves the problem of reducing the risk of water seepage accumulation. First, the leak-proof bottom layer 1 directly shields the roof surface from contact with external moisture, acting as a barrier. Second, the V-shaped drainage guide channel 2, combined with the hydrophobic texture 22, significantly reduces the probability of localized water accumulation and quickly directs the accumulated water flow to the drainage area. The reinforced support plate 3 enhances system stability and extends service life. Simultaneously, the sealing layer 4 covering the channel opening and the inclined diversion plate 5, which accelerates water flow, form a dual protection mechanism, minimizing the possibility of leakage even in the event of an accident. Therefore, this complete solution successfully and effectively prevents the problem of water seepage accumulation.

[0035] like Figures 2-4 As shown, in one embodiment, the drainage guide channel 2 of the waterproofing substrate for building roofs of this application further optimizes the water flow direction by adding multiple diversion ribs 7 inside its V-shaped structure. These diversion ribs 7 are specifically located inside the drainage guide channel 2 and are arranged along the expected path of the water flow. The presence of the diversion ribs 7 makes the water flow more orderly when passing through the drainage guide channel 2 and significantly reduces the risk of water seepage due to turbulence or accidental diversion. By precisely designing the number and position of the diversion ribs 7, the entire drainage system can maintain efficient and stable performance in practical applications.

[0036] The diversion ribs 7 are specifically constructed from materials with high elasticity and good waterproof properties. Their cross-sectional shape can be trapezoidal or semi-circular to match the design requirements of the V-shaped structure. For example, in one implementation, several diversion ribs 7 are evenly arranged on the inner wall of the drainage guide channel 2 and bonded to it using adhesive or embedded fixing methods. Simultaneously, these diversion ribs 7 work closely with the sealing layer 4 to effectively control the risk of water leakage even under complex weather conditions. Throughout the assembly process, the diversion ribs 7 need to be strictly aligned with the predetermined trajectory to ensure that the final drainage path is consistent and continuous.

[0037] like Figures 2-4 As shown, in one embodiment, the drainage guide channel 2 of the waterproofing substrate for building roofs of this application has a V-shaped structure. This structure has good water flow guidance capability, and reinforcing ribs 8 are provided on both sides to optimize the structural rigidity of the entire waterproofing substrate. The reinforcing ribs 8 are installed on the inner walls of both sides of the drainage guide channel 2, which can significantly reduce the risk of deformation of the drainage guide channel 2 caused by external mechanical forces. The reinforcing ribs 8 themselves are slender strip structures, evenly distributed along the length direction of the drainage guide channel 2, and connected to the drainage guide channel 2 by welding or bonding, further enhancing the reliability of the structural connection.

[0038] Specifically, the reinforcing ribs 8 can be integrally molded onto both sides of the drainage guide channel 2 using injection molding, or they can be manufactured separately and then assembled for fixation. During this process, special attention needs to be paid to the positional accuracy of the reinforcing ribs 8 and the connection strength between them and the inner wall of the drainage guide channel 2 to ensure that there are no loosening or detachment issues. Furthermore, to adapt to the load conditions in actual use, reinforcing ribs 8 of different thicknesses or materials can be selected to meet specific design requirements.

[0039] like Figure 3 and Figure 4 As shown, in one embodiment, the anti-clogging micropores 21 of the waterproof substrate for building roofs of this application are arranged in a staggered pattern. These anti-clogging micropores 21 are disposed on the inner wall surface of the drainage guide channel 2, and their staggered arrangement achieves uniform water flow and restricts impurity deposition. The gradually decreasing pore size from bottom to top is achieved using a gradient pore structure, thereby enabling the sequential filtering and blocking of impurities of different particle sizes. In actual installation, these micropores specifically cover the key water flow area of ​​the entire drainage guide channel 2, ensuring a continuous and unobstructed water flow path.

[0040] For example, the anti-clogging micropores 21 can be formed on the inner surface of the drainage guide channel 2 by laser drilling or machining. Their size variation is achieved by adjusting the processing parameters layer by layer, such as gradually reducing the laser beam diameter to accommodate differences in vertical position. Furthermore, the staggered arrangement is achieved by precisely planning the spacing and position of each row of micropores, ensuring that the gaps between the pores fully meet the hydrodynamic requirements without interfering with the smooth flow of water. This layout, combined with the gradual size variation characteristic, further enhances the long-term stability of the system under complex water quality conditions while ensuring drainage efficiency.

[0041] like Figures 2-4 As shown, in one embodiment, the hydrophobic texture 22 of the waterproof substrate for building roofs of this application is designed to unfold in the V-shaped bottom area of ​​the drainage guide channel 2. The hydrophobic texture 22 is composed of wavy lines and is laid out along the bottom of the V-shape to ensure that its coverage area minimizes water stagnation during drainage. This design avoids potential seepage problems caused by water stagnation by adjusting the contact path of the water flow. In addition, the geometry of the hydrophobic texture 22 has a specific regularity and matches the overall shape of the drainage guide channel 2 to achieve an efficient guiding function.

[0042] For example, the wavy lines of the hydrophobic texture 22 can be created using a high-precision molding process or by curing a coating material. Specifically, the bottom material of the drainage guide channel 2 is first processed to form a predetermined alternating structure of wavy protrusions and grooves 14, while ensuring that the entire surface of the structure is smooth and flawless. Subsequently, the waterproof capability can be further enhanced by spraying a hydrophobic coating, so that the function of the hydrophobic texture 22 can be fully realized and operate stably in practical application scenarios.

[0043] In one embodiment, the sealing layer 4 and drainage guide channel 2 of a waterproofing substrate for building roofs according to this application are seamlessly connected through a specific connection method. Specifically, the sealing layer 4 tightly covers the opening of the drainage guide channel 2, which is located above the waterproofing base layer 1, and reinforced support plates 3 are provided on both sides to enhance the overall strength. To ensure that there are no gaps that could cause leakage at the joint area, the substrate is designed with a unique integrated structure, in which the sealing layer 4 and drainage guide channel 2 are not simply glued or mechanically fixed, but are permanently connected directly using a special process. This design not only enhances the tightness of the joint but also improves the reliability of long-term use.

[0044] For example, a strong connection between the sealing layer 4 and the drainage guide channel 2 can be achieved using hot-melt welding technology. Specifically, utilizing the thermoplastic properties of the polymer material itself, the sealing layer 4 and the drainage guide channel 2 are heated to an appropriate temperature and then rapidly pressed together, forming an inseparable integrated structure. This method effectively avoids the aging or detachment problems that may occur with traditional adhesive bonding, further enhancing the overall performance of the leak-proof substrate.

[0045] like Figure 2 As shown, in one embodiment, the reinforcing support plate 3 of the waterproofing substrate for building roofs of this application, through its unique internal structural design, effectively enhances the support for the drainage guide channel 2 while maintaining overall lightweight design. The interior of the reinforcing support plate 3 contains several lightweight reinforcing cores 11, which are typically made of low-density but high-strength materials, such as foamed metal composites or fiber-reinforced plastics. The lightweight reinforcing cores 11 are tightly embedded within the reinforcing support plate 3, forming a grid-like arrangement. This arrangement ensures overall rigidity while avoiding the addition of extra weight. Specifically, the reinforcing support plate 3 and the drainage guide channel 2 are adjacent to each other and physically connected to form a single unit.

[0046] Specifically, in the production process of the reinforced support plate 3, the outer shell is first processed according to a predetermined shape. Then, multiple independently formed lightweight reinforcing cores 11 are arranged according to certain rules and filled into the inner cavity of the reinforced support plate 3. Finally, the two are tightly bonded together using processes such as hot pressing, bonding, or integral molding. During this process, it is also necessary to ensure that the lightweight reinforcing cores 11 are evenly distributed in the area near the drainage guide channel 2 to further improve the support effect. For example, for a longer drainage guide channel 2 structure, more reinforcing cores can be concentrated near each key load-bearing point to optimize local mechanical properties.

[0047] like Figure 2 As shown, in one embodiment, the fastener 6 of the waterproofing substrate for building roofs according to this application achieves a secure connection with the building roof through a special structural design. The fastener 6 consists of double-layer snap-fit ​​pieces 13, which are arranged in parallel around the perimeter of the waterproofing substrate 1, and their specific installation positions are located near the edges of the waterproofing substrate 1. The spacing between the double-layer snap-fit ​​pieces 13 can be adjusted according to actual usage requirements to accommodate the size of different types of mounting bolts. The double-layer snap-fit ​​pieces 13 are integrally formed onto the surface of the waterproofing substrate 1 through a specific process, forming a robust whole.

[0048] To achieve the fixing function, the pre-installed bolts pass through the reserved holes in the double-layer snap-fit ​​pieces 13 and the leak-proof bottom layer 1, directly securing the entire leak-proof substrate to the building roof. During this process, the double-layer snap-fit ​​pieces 13, as a key component for force transmission, not only disperse the stress points and reduce the impact of localized stress on the substrate material properties, but also prevent structural damage caused by stress concentration during fixing. Furthermore, the fixing fasteners 6, through their reasonable layout and stable connection, ensure that the substrate remains stable for a long period during use.

[0049] For example, during fixing, first ensure that the double-layer snap-fit ​​pieces 13 are accurately aligned with the pre-set connection points on the building roof, and then use appropriate size mounting bolts to position and tighten them one by one. Throughout the operation, the force applied by the bolts will be evenly distributed to the leak-proof bottom layer 1 through the double-layer snap-fit ​​pieces 13, thereby ensuring the safety and stability of the structure after installation.

[0050] like Figure 2 As shown, in one embodiment, the waterproofing substrate 1 of a building roof waterproofing base material of this application has a groove 14 in a specific area to accommodate the bottom edge of a drainage guide channel 2. The groove 14 faces the drainage guide channel 2, and through reasonable size and shape design, the drainage guide channel 2 can be stably embedded therein after installation. This design clarifies the relative installation relationship between the drainage guide channel 2 and the waterproofing substrate 1, avoiding displacement or offset of the drainage guide channel 2 during actual use. At the same time, the presence of the groove 14 not only serves a positioning function, but also provides a simple and quick assembly method for the two.

[0051] Specifically, the groove 14 can be constructed as a regularly shaped recessed section with chamfered or rounded edges to facilitate smooth insertion and stable contact of the bottom edge of the drainage guide groove 2. For example, by matching the depth of the groove 14 with the height of the bottom edge of the drainage guide groove 2, excessive clearance during assembly is ensured. Furthermore, a cushioning material may be added to the inner wall of the groove 14 to further enhance the fixing effect and prevent structural loosening due to vibration or external forces.

[0052] In practical operation, when this device is used, the leak-proof base layer 1 is placed on the roof surface to form a preliminary waterproof protective layer. Then, the drainage guide channel 2 is placed on top of the leak-proof base layer 1, effectively guiding water flow to the designated drainage area through its V-shaped structure. The surface's anti-clogging micropores 21 reduce impurity accumulation, while the hydrophobic texture 22 on its bottom reduces the risk of water penetration. On this basis, the reinforcing support plate 3 is connected to the drainage guide channel 2 to enhance the overall structural strength, while the sealing layer 4 covers the opening of the drainage guide channel 2 to prevent water from seeping into the substrate. Next, the inclined drainage plate 5 is fixed to one end above the sealing layer 4, enabling the water flow from the roof to be quickly and orderly guided into the drainage guide channel 2 for discharge. Finally, fixing fasteners 6 are distributed around the perimeter of the leak-proof base layer 1 and securely installed on the roof using fasteners to ensure stable operation of the device.
