[0032] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0033] Reference Figures 1 to 3 , the present application provides a complex roof drainage system, comprising:

[0034] Roof 1, the roof 1 is arc-shaped, and multiple water guide columns 2 are respectively arranged on both sides of the top center line of the roof 1, and the top of the water guide column 2 is close to the top center line of the roof 1; a water guide trough 3 is provided in the gap between two adjacent water guide columns 2; a support column 4, close to the end of the roof 1 and connected to the bottom surface of the roof 1, the support column 4 is provided with a groove 41 near the roof 1; a water collecting box 5, arranged in the groove 41, a water collecting box 5 is provided with a water collecting box 5 on the top, the water collecting box 5 is connected to the water guide trough 3, the water collecting box 5 is used to collect rainwater from the water guide trough 3, and a water outlet is provided at the bottom of the water collecting box 5; a water pipe 6, one end of which is connected to the water outlet, the water pipe 6 is connected to the support column 4, and along the support column 4, the other end of the water pipe 6 is connected to the ground drainage system.

[0035] This embodiment provides a complex roof drainage system. The roof 1 is made of a metal material (such as steel plate) or a new composite material with a certain strength and waterproof properties. It is bent into an arc shape using a specific mold or processing technique. This arc shape facilitates the flow and collection of rainwater to both sides under the action of gravity. Positioning marks or grooves are pre-installed at the top centerline of the roof 1 to ensure more precise positioning of the water guide columns 2 when they are subsequently installed near the top centerline. By installing multiple water guide columns 2 on the roof 1, rainwater that drips onto the roof 1 or the water guide columns 2 is directed back into the water guide troughs 3 between the columns 2 during rain. The V-shaped water guide troughs 3 facilitate the rapid channeling of rainwater into the water collection tank 5. The water guide troughs 3 have a certain inclination, determined according to the roof's inclination (typically 1% to 3% toward the water collection tank 5), to ensure smooth flow of rainwater into the water collection tank 5. Rainwater flows along the extension of roof 1, along gutter 3, to sump 51. Gutter 3 collects the rainwater and flows it into sump 5. The water is then discharged into the ground drainage system through aqueduct 6 connected to the bottom of sump 5. The provision of multiple gutter columns 2 forms multiple gutter 3 on roof 1. Increasing the number of gutter 3 disperses rainwater from roof 1 into multiple small streams, improving drainage and breaking up the rainwater flow. This reduces the pressure on sump 5 and allows for better collection of rainwater from roof 1.

[0036] Support columns 4 are constructed of concrete, steel, or aluminum alloy. Concrete columns offer excellent stability and cost-effectiveness, steel columns are strong and easy to construct, and aluminum alloy columns are lightweight and corrosion-resistant. A slot 41 is provided at the end of support column 4 near roof 1. The dimensions of slot 41 are designed based on the dimensions of water collection tank 5 to ensure smooth insertion and secure installation. The inner wall of slot 41 can be treated with rust or corrosion protection, such as by applying anti-rust paint or installing an anti-corrosion lining, to extend the service life of support column 4. The water collection tank 5 is constructed of plastic or metal. The top water collection trough 51 is an open, elongated groove. Its width matches the outlet of the water channel 3, and its depth is determined based on the expected maximum rainfall and water collection rate, typically between 100 mm and 300 mm, ensuring a maximum water capacity of at least 6 liters. The bottom water outlet of the water collection tank 5 is located at the lowest point and fitted with a filter to prevent debris from entering the water pipe 6 and causing blockage. Once the water collection tank 5 is placed in the slot 41 of the support column 4, it can be secured to the support column 4 using bolts, clamps, or welding to ensure it does not wobble or shift under the weight of rainwater and external forces such as wind. The water pipe 6 is constructed of plastic or metal tubing. The diameter of the tubing is calculated based on the roof area and rainfall to ensure that rainwater can be drained promptly and smoothly to the ground drainage system. When connecting the water pipe 6 to the water outlet of the water collection tank 5, use sealing rings or threaded connections to ensure a tight, leak-proof connection. Pipe clamps can be used to secure the water pipe 6 along the support column 4, spaced 1 to 2 meters apart. They securely fasten the water pipe 6 to the surface of the support column 4. Rubber pads or other cushioning materials can be placed where the water pipe 6 contacts the support column 4 to prevent damage to the support column 4 and the water pipe 6 from prolonged friction. When connecting the other end of the water pipe 6 to the inspection well or drainage pipe of the ground drainage system, ensure a smooth connection that complies with drainage regulations to avoid backflow or leakage.

[0037] In this application, the setting of the water guide column 2 can divert rainwater to a designated point, prevent rainwater from flowing out along the edge of the roof 1, avoid rainwater leakage and seepage, prevent rainwater from flowing into the room, protect indoor buildings, and play a protective role on interior decoration.

[0038] By placing the water collection tank 5 at a high location, the rainwater inside is concentrated at a high level. A siphon effect draws the rainwater downward through the aqueduct 6. Advanced siphon technology is employed between the aqueduct 6 and the water collection tank 5, leveraging the pressure differential created by the water level difference to rapidly drain the rainwater through the aqueduct 6 without the need for external power. This siphon technology eliminates the need for additional power to drain the rainwater from the water collection tank 5, reducing energy consumption and significantly lowering system maintenance costs. The aqueduct 6 on the roof 1 is designed as a multi-stage siphon system, ensuring efficient drainage under varying rainfall intensities. This improves the efficiency of the drainage system and makes the entire system more efficient and reliable.

[0039] In one feasible embodiment, the rainwater in the water collection tank 5 can be recycled and reused. A rainwater collection system can be provided, with the aqueduct 6 connected to the rainwater collection system. By integrating the drainage system of the roof 1 with the rainwater collection system, the collected rainwater can be used for non-potable purposes such as landscaping irrigation and toilet flushing, thereby conserving precious water resources. Furthermore, a filtration device can be installed in the rainwater collection system to filter the collected rainwater for reuse, ensuring that the collected rainwater meets usage standards and is in line with environmental protection and sustainable development concepts.

[0040] At the same time, the water collecting tank 5 is hidden in the slot 41 of the support column 4, so that the water collecting tank 5 can be hidden in the decorative structure of the roof 1, preventing the water collecting tank 5 from leaking out, which can not only increase the aesthetics without affecting the overall appearance of the building, but also can prevent the roof 1 from leaking and seeping water when the water collecting tank 5 overflows. In this application, the water pipe 6 is also connected to the support column 4, which can hide the position of the water pipe 6. The setting of the water guide column 2 on the roof 1, combined with the curved shape of the roof 1, can make the roof 1 drainage system more beautiful as a whole, so that the design of the entire roof 1 drainage system fully considers the aesthetics of the building. It ensures the realization of the function without affecting the overall appearance of the building and enhances the aesthetic value of the building.

[0041] In one feasible embodiment, a backup drainage device may also be included. The backup drainage device may be a pump disposed in the water collecting tank 5, which can serve as a backup drainage method in extreme weather conditions when the rainwater in the water collecting tank 5 cannot be discharged in a short period of time through the water conduit 6 or when the water conduit 6 is blocked, causing the rainwater to drain slowly. By providing a backup drainage device, when the main drainage system fails or exceeds its processing capacity, the backup drainage device can be quickly activated to ensure that rainwater does not accumulate on the roof 1, thereby avoiding potential structural damage risks. The backup drainage device may also be a water conduit 6 disposed on one side of the water collecting tank 5 that also uses siphon technology. The use of a backup drainage device that does not rely on power can ensure that the drainage function can still operate normally even in emergency situations such as power outages.

[0042] The above technical solution can achieve good water-guiding and water-repellent effects, increase service life, and achieve beautiful appearance while also having excellent waterproof and water-repellent effects.

[0043] In an implementable embodiment, the water guide columns 2 on both sides of the roof 1 are arranged at equal intervals, and the top ends of the water guide columns 2 are arranged in a cross shape on the roof 1 in sequence.

[0044] In this embodiment, the top ends of the water guide columns 2 are arranged in a cross shape on the roof 1 in sequence, which can divide rainwater into multiple water collection areas. Each water collection area is a water guide trough 3 between each water guide column 2. Each area guides rainwater into the water collection tank 5 through an independent drainage trough, effectively avoiding the problem of local water accumulation.

[0045] In an implementable embodiment, it also includes a water baffle 8, which is arranged in the gap between two adjacent water guide columns 2. There is also a gap between the bottom of the water baffle 8 and the water guide groove 3. The distance between the bottom of the water baffle 8 and the bottom of the water guide groove 3 is 50 mm.

[0046] In this embodiment, baffle 8 is made of plastic or thin metal. Its shape matches the gap between adjacent water guide columns 2, and its width is slightly smaller than the gap width for ease of installation. During installation, baffle 8 is vertically inserted into the gap between adjacent water guide columns 2, leaving a 50 mm gap between its bottom and the water channel 3. The top of baffle 8 can be connected and fixed to the water guide column 2 or the underside of the roof 1 to prevent it from shaking or tilting. This ensures that the water flow is effectively separated during rainwater flushing, reduces turbulence in the water channel 3, and improves drainage efficiency.

[0047] A plurality of water-blocking plates 8 are arranged at equal intervals along the extension direction of the gap of the water guide column 2. The distance between the bottom of each water-blocking plate 8 and the bottom of the water guide trough 3 is 50 mm. The water guide trough 3 is used to divert rainwater into the water collecting tank 5. In extreme weather, a large amount of rainwater will flow into the water collecting tank 5 in a short time. The opening of the water collecting tank 5 is fixed. In order to prevent the rainwater from being unable to be collected in the water collecting tank 5 in time, the water-blocking plates 8 are used to partially block the rainwater and slow down the flow of rainwater to the water collecting tank 5, so that the water collecting tank 5 can discharge the rainwater in the box in time.

[0048] In an implementable embodiment, a water retaining plate 7 is further included, and the water retaining plate 7 is arranged at the end of the roof 1.

[0049] In this embodiment, a water retaining plate 7 is installed at the eaves of the roof 1 to prevent rainwater from splashing onto the roof 1. The installation of the water retaining plate 7 not only prevents splashing but also acts as a water barrier. The water retaining plate 7 is 600mm high, effectively preventing rainwater from splashing and maintaining an unobstructed drainage channel. The installation of the water retaining plate 7 not only improves drainage efficiency but also ensures the long-term stable operation of the drainage system. The water retaining plate 7 is typically made of aluminum alloy, which offers excellent corrosion resistance and strength, suitable for roofs exposed to the outdoors for extended periods. The water retaining plate is generally elongated with an L-shaped cross-section. The vertical portion is 600mm high, preventing rainwater from splashing and directing water flow. The horizontal portion is 100mm wide and is secured to the eaves of the roof 1. Holes are pre-drilled at the edge of the eaves of the roof 1 and the horizontal portion of the water retaining plate 7 is secured to the eaves using stainless steel bolts, with bolt spacing of 300mm to ensure a secure installation. Waterproof sealant is applied to the contact area between the water retaining plate 7 and the eaves to prevent rainwater leakage.

[0050] In one embodiment, the roof 1 includes a waterproof layer made of an aluminum-magnesium-manganese composite material. The roof 1 includes an aluminum-magnesium-manganese metal layer, a stainless steel metal layer, and an aluminum plate metal layer from top to bottom.

[0051] In this embodiment, the roof 1 uses an aluminum-magnesium-manganese metal layer as a waterproof material, which is combined with a stainless steel metal layer and an aluminum plate metal layer to enhance the overall aesthetics and durability of the roof. The use of a standing seam aluminum-magnesium-manganese metal layer enables the roof 1 to have a thermal insulation effect and has Class I waterproof performance. The aluminum-magnesium-manganese metal layer is not only corrosion-resistant and high-strength, but also has excellent thermal insulation functions, thereby improving the energy efficiency of the building. The aluminum-magnesium-manganese metal layer has good waterproof and moisture-proof properties, and can achieve 100% structural waterproofing through a standing seam bite design. In addition, the aluminum-magnesium-manganese metal layer can be fixed using a concealed buckle plus a mechanical lock edge, which avoids screws passing through the roof, thereby effectively preventing potential water leakage hazards.

[0052] In this application, a 1mm thick aluminum-magnesium-manganese metal layer is used as a waterproof layer. It achieves 100% structural waterproofing through a vertical lock-edge bite design. The aluminum-magnesium-manganese metal layer can use hidden buckles and mechanical lock edges. For example, using professional vertical edge and bite equipment, the vertical edges of the two boards are bitten along the length of the slats, so that the roof or wall is connected as a whole. No glue is required, which effectively avoids the hidden danger of water leakage caused by screws passing through the roof. The aluminum-magnesium-manganese metal layer has Class I waterproof performance. At the same time, the aluminum-magnesium-manganese metal layer has good waterproof, moisture-proof, thermal insulation and heat insulation functions. The stainless steel metal layer is 3mm thick and is located below the aluminum-magnesium-manganese metal layer. It plays a role in enhancing the overall structural strength of the roof and providing a certain auxiliary waterproofing effect. The material selection must comply with the relevant building metal material standards and must be closely fitted with the aluminum-magnesium-manganese metal layer to ensure the stability and sealing of the overall structure. The aluminum plate metal layer is also 3mm thick and is located at the bottom as a decorative layer. While meeting certain decorative and aesthetic requirements, it also plays a certain protective role for the overall structure of the roof. Its surface can be treated accordingly (such as spraying, etc.) to make its appearance more textured and firmly connected to the stainless steel metal layer above.

[0053] The use of a 1mm thick aluminum-magnesium-manganese metal waterproof layer and a 3mm stainless steel metal layer, supplemented by 3mm thick aluminum plate decoration, ensures the stability and sealing of the structure. The roof of this application also has a double-slope drainage, with a drainage slope of 60%-100% from the center to both sides, ensuring that rainwater can be discharged quickly and smoothly, effectively preventing water accumulation. This design conforms to the principle of "combining water prevention and drainage", reducing the burden on the roof waterproof layer by quickly draining rainwater and reducing the chance of leakage.

[0054] The aluminum-magnesium-manganese metal standing seam system uses specialized standing and locking equipment to interlock the edges of two panels along the length of the strips, thus connecting the roof or wall into a single piece. This system requires no glue and achieves 100% structural waterproofing. The 180° flat-lock connection and unique waterproof structure further enhance waterproofing performance.

[0055] In an implementable embodiment, six water guide columns 2 are provided, with three water guide columns 2 provided on each side of the roof 1 , and the shape of the water guide columns 2 is pyramidal.

[0056] In this embodiment, three pyramidal water guide columns 2 are arranged on both sides of the roof 1. The pyramidal arrangement can reduce the impact force of the water guide columns 2 when raindrops fall on the water guide columns 2, thereby increasing the service life of the water guide columns 2. The water guide columns 2 carefully divide the entire roof into 8 water collection areas, and each area is guided to the water collection tank 5 through an independent water guide trough 3, effectively avoiding the problem of local water accumulation. Figure 1, a structural schematic diagram showing six water guide columns 2 are provided on the roof 1 , but the present application does not limit the number of water guide columns 2 , and the number of water guide columns 2 on the roof 1 may also be 8 or 10.

[0057] In an implementable embodiment, the shape of the water guide column 2 can also be conical. Setting the water guide column 2 to a conical shape can increase the wind resistance of the water guide column 2, better disperse the pressure on the water guide column 2, reduce the local stress concentration of the water guide column 2, and increase the service life of the water guide column 2. At the same time, setting the water guide column 2 to a conical shape can increase the architectural beauty of the water guide column 2.

[0058] Continue to refer to Figure 4 In an implementable embodiment, the support column 4 is supported by a lattice column support steel frame 43, and the water pipe 6 is set in the support column 4 and connected to the ground drainage system along the support column 4.

[0059] The support column 4 includes an outer plate 42 , which wraps the lattice column support steel frame 43 . Two adjacent outer plates 42 are connected by a connecting plate 44 , and the end of the connecting plate 44 close to the outer plate 42 is connected to the outer plate 42 .

[0060] In this embodiment, support columns 4 are supported by lattice column support steel frames 43. Lattice column support steel frames 43 are compression-bending components, which conserves material. Lattice column support steel frames 43 distribute material away from the axis of inertia, ensuring enhanced component bending resistance under the same axial resistance conditions while also conserving material. Lattice column support steel frames 43 also have an axis of symmetry. When the component loses overall stability due to axial compression, torsional and flexural-torsional buckling will not occur, resulting in improved support. The water conduit 6 is located within the support column 4, concealing it and preventing it from affecting the building's aesthetics.

[0061] The lattice column support steel frame 43 is constructed from high-strength, corrosion-resistant steel. By strategically arranging the lattice column support steel frame 43 away from the axis of inertia, the lattice column support steel frame 43 enhances its bending resistance while maintaining consistent axial resistance, while also conserving material. For example, the lattice column support steel frame 43 can be welded together into a lattice structure using I-beams, channel steel, and other materials according to design requirements. This lattice column support steel frame 43 has an axis of symmetry. When the component is subjected to axial compression and loses overall stability, it will not experience torsional buckling or flexural-torsional buckling, providing excellent support.

[0062] The outer panel 42 wraps the lattice column support steel frame 43, and two adjacent outer panels 42 are connected by a connecting plate 44. The end of the connecting plate 44 close to the outer panel 42 is connected to the outer panel 42, which can avoid the connection weld between the connecting plate 44 and the outer panel 42 being exposed, which affects the appearance.

[0063] Although the present invention has been illustrated and described with reference to certain preferred embodiments of the present invention, it should be understood by those skilled in the art that the above description is provided to further illustrate the present invention in conjunction with specific embodiments, and that the present invention should not be construed as being limited to these descriptions. Those skilled in the art may make various changes in form and detail, including simple deductions or substitutions, without departing from the spirit and scope of the present invention.
