Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to a novel water-guiding and anti-clogging metal roof panel. Background Technology
[0002] In the field of industrial plant construction, the smoothness of the roof drainage system is directly related to the structural safety and service life of the plant. Currently, most industrial plant roofs generally use gutters as the core drainage facility. To ensure that rainwater can naturally flow along the roof to the gutters, the roof of the plant is usually designed as a sloping structure with a specific gradient. Although this design can meet the basic drainage requirements, under the action of gravity, garbage, fallen leaves, dust and other debris accumulated on the roof will continuously slide into the gutters along the roof slope. This not only easily causes blockage of the gutter cavity, but also forms silt at the drain outlet, preventing rainwater from being discharged in a timely manner.
[0003] Clogged gutters cause water accumulation and silt buildup, which significantly increases the structural load on the gutters. Over time, this can lead to deformation and cracking, posing a safety hazard to the overall structural stability of the roof. Furthermore, prolonged water retention accelerates the corrosion of the gutter's metal components, shortening the drainage system's lifespan. More seriously, during heavy rainfall, the roof's water volume surges, and a large amount of rainwater flows rapidly along the roof slope, ultimately impacting the waterproofing membrane seams on the inner gutter sidewalls with considerable force. This repeated and intense water erosion gradually damages the seal at the seams, causing the waterproofing membrane to peel and crack, creating leakage channels and leading to internal leaks in the factory. This not only disrupts normal production operations but also damages equipment and goods within the factory.
[0004] Therefore, developing a roof panel that can prevent water blockage and protect the waterproof structure of the gutter from the source has become a key problem that urgently needs to be solved in the current industrial plant roof drainage system. Utility Model Content
[0005] To address the aforementioned problems, this utility model provides a novel water-guiding and anti-clogging metal roof panel.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a novel water-guiding and anti-clogging metal roof panel, comprising an inclined metal roof panel body, wherein the lower end of the metal roof panel body extends out of the inner edge of the gutter and at least two rows of water-guiding baffles are spaced apart along the length direction of the extended portion of the panel, the surface of the water-guiding baffles is perpendicular to the surface of the metal roof panel body, the length direction of the water-guiding baffles is consistent with the width direction of the metal roof panel, and several water-guiding baffles are spaced apart in each row, and each water-guiding baffle is arranged in the interrib plane area of the metal roof panel body.
[0007] Furthermore, the spacing between two adjacent water guide baffles in the same row is less than or equal to 30mm.
[0008] Furthermore, the multiple rows of water-guiding baffles are arranged in a staggered manner.
[0009] Furthermore, the length of the lower end of the metal roof panel extending beyond the inner edge of the gutter is half the width of the gutter.
[0010] Furthermore, a drainage hole is provided on the upper side of the water guide baffle on the metal roof panel body, and a dustproof net is provided on the bottom surface of the portion of the metal roof panel body extending out of the inner edge of the gutter.
[0011] Furthermore, the length of the dustproof net is the width of the metal roof panel body minus 10mm and it is centered, the width of the dustproof net is half the width of the gutter minus 40mm, and the lower edge of the dustproof net is no more than 20mm away from the lower edge of the metal roof panel body.
[0012] Furthermore, the dustproof net has rectangular holes with a side length of less than or equal to 10 mm.
[0013] In summary, this utility model has the following beneficial effects: In this application, by setting at least two rows of water-guiding baffles at intervals at the lower end of the metal roof panel body, the water-guiding baffles perpendicular to the roof surface can effectively block garbage, fallen leaves and other debris carried by rainwater as it slides down, preventing garbage, fallen leaves and other debris from directly entering the gutter and causing gutter blockage; the baffles are arranged at intervals along the length of the panel and located in the inter-rib plane area of the roof panel, which can not only adapt to the conventional rib structure of the metal roof panel without affecting the original mechanical properties of the roof, but also guide the water flow through multiple rows, so that rainwater flows in an orderly manner along the gaps between the baffles, improving drainage efficiency.

[0016] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0017] like Figure 1-6 As shown in the figure, this application discloses a novel water-guiding and anti-clogging metal roof panel, including a metal roof panel body 10 and a water-guiding baffle 20. The metal roof panel body 10 is inclinedly arranged on the building roof. When arranged, the lower end of the metal roof panel body 10 extends out of the inner edge of the gutter by half the width of the gutter, so that the lower end of the metal roof panel body 10 extends to the middle of the gutter. In this way, the water flows smoothly into the middle of the gutter through the extended section, instead of flowing along the edge of the gutter. On the one hand, it reduces the risk of rainwater forming vortices or siltation in the gutter and improves drainage smoothness; on the other hand, it can prevent rainwater from directly impacting the sidewall of the gutter, reduce the erosion and damage to the joints of the waterproof membrane on the inner side of the gutter, and extend the service life of the waterproof layer.
[0018] A water-guiding baffle 20 is installed on the surface of the portion of the metal roof panel body 10 that extends beyond the inner edge of the gutter, and at least two rows are spaced apart along the length of the metal roof panel body 10. When installed, the surface of the water-guiding baffle 20 is perpendicular to the surface of the metal roof panel body 10, and the length direction of the water-guiding baffle 20 is consistent with the width direction of the metal roof panel. The water-guiding baffle 20, perpendicular to the roof surface, effectively blocks garbage, fallen leaves, and other debris carried by rainwater as it slides down, preventing these debris from directly entering the gutter and causing blockage.
[0019] Several water-guiding baffles 20 are arranged in each row at intervals, with each baffle 20 positioned within the ribbed plane of the metal roof panel body 10. This arrangement adapts to the conventional ribbed structure of the metal roof panel without affecting its original mechanical properties, while the multiple rows guide water flow, allowing rainwater to converge orderly along the gaps between the baffles and improving drainage efficiency. The spacing between two adjacent water-guiding baffles 20 in the same row is less than or equal to 30mm to prevent debris and other contaminants from flowing between the baffles 20. The spacing between the multiple rows of water-guiding baffles 20, the distance between the baffles 20 and the edge of the metal roof panel, and the dimensions of the baffles 20 themselves are all adjusted according to the width and overhang length of the metal roof panel body 10 to ensure the water-repellent and debris-blocking effect of the baffles. In practice, the multiple rows of water-guiding baffles 20 are arranged in a staggered manner. This design fills the straight gaps created by the spacing of a single row of baffles, allowing debris to be intercepted by multiple rows of baffles as it slides down, significantly reducing the probability of small debris leaking into the gutter. At the same time, the staggered arrangement does not affect the flow area of rainwater through the gaps in the baffles, strengthening the anti-blocking function while avoiding the risk of water accumulation on the roof, achieving a balance between blocking debris and not blocking water, and optimizing interception efficiency.
[0020] Preferably, a drainage hole 11 is provided on the metal roof panel body 10 above the water guide baffle 20, and the size of the drainage hole 11 is the same as the size of the water guide baffle 20. When making the drainage hole 11, only the upper side and the left and right sides are cut on the metal roof panel body 10. Then, the metal sheet cut out of the drainage hole 11 area is folded upward along the lower side by 90 degrees. The folded metal sheet forms the water guide baffle 20, and the original position of the metal sheet forms the drainage hole 11. In this way, the water guide baffle 20 and the drainage hole 11 can be formed using the original structure of the metal roof panel body 10 without increasing the load on the metal roof panel body 10.
[0021] A dustproof net 12 is installed on the bottom surface of the part of the metal roof panel body 10 that extends out of the gutter. The drainage hole 11 is blocked by the dustproof net 12. The dustproof net 12 has a mesh structure, which allows rainwater to pass through, while garbage, fallen leaves and other debris are blocked by the dustproof net.
[0022] Specifically, the dustproof net 12 is made of metal with rectangular mesh openings and a side length of 10mm or less. The length of the dustproof net 12 is the width of the metal roof panel 10 minus 10mm, and it is centered. The width of the dustproof net 12 is half the width of the gutter minus 40mm, and the lower edge of the dustproof net 12 is no more than 20mm from the lower edge of the metal roof panel 10. During installation, the dustproof net 12 is spot-welded to the bottom surface of the metal roof panel 10 on all four sides to ensure a secure installation and prevent it from falling off.
[0023] The working principle of this novel water-guiding and anti-clogging metal roof panel in this embodiment is as follows: When it rains, rainwater carrying garbage, fallen leaves, and other debris flows downwards along the metal roof panel body 10. When passing through the area where the water-guiding baffle 20 is arranged, the rainwater continues to flow downwards from the drainage hole 11 on the upper side of the water-guiding baffle 20 and the gap between the water-guiding baffle 20 and the baffle 20. Meanwhile, the garbage, fallen leaves, and other debris are blocked by the water-guiding baffle 20 and the dustproof net 12 and accumulate in the area on the upper side of the water-guiding baffle 20. This effectively prevents garbage, fallen leaves, and other debris from accumulating in the gutter and causing gutter blockage. The metal roof panel in this embodiment also requires manual cleaning. The specific cleaning cycle is determined according to the local rainfall frequency, surrounding garbage, fallen leaves, dust, and other actual conditions.
[0024] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
