Description

Technical Field

[0001] This utility model relates to the field of building materials, and in particular to a roofing panel. Background Technology

[0002] A tool shed is a storage room used to store various household or industrial tools. With the development of science and technology, the materials for tool sheds have gradually shifted from various brick and tile structures to wood-plastic composite (WPC) boards, which are easier to transport and disassemble. Although building tool sheds with WPC boards allows for faster material transportation, assembly, and disassembly, waterproofing remains a challenge.

[0003] The simplest way to waterproof is to use wood-plastic composite boards on the roof of a tool shed, with the gaps between adjacent boards extending from the roof to the eaves, so that the gaps follow the slope of the roof, thus minimizing the risk of rainwater seeping into the shed.

[0004] Existing technology CN110894743A discloses a prefabricated roof panel, including a standard panel, a sealing strip, roof panel crests, a groove, a male overlap joint, a female overlap joint, and end sealing plates. The standard panel is hollow inside and open at both ends, with end sealing plates fitting over each opening. The standard panels are placed parallel to each other. A male overlap joint is provided on the bottom of one side of the standard panel, and a female overlap joint that mates with the male overlap joint is fixed on the bottom of the other side. Roof panel crests are symmetrically fixed on both sides of the top surface of the standard panel, and a groove is provided on the mating surface of the roof panel crests. A sealing strip is fitted into the groove. Fixing components are installed at the splicing positions on the sides of the standard panel. This prefabricated roof panel achieves stable sealing installation through parallel and tight splicing, combined with the locking of the sealing strip. It has high waterproof performance, long service life, and the entire installation operation is convenient and easy to maintain later.

[0005] In existing technologies, although roofing panels with symmetrically fixed crests on both sides of the top surface of a standard panel, and grooves on the mating surfaces of the crests, can achieve good waterproof sealing by locking the sealing strip into the grooves and covering the crests, the construction of tool huts using existing roofing panels requires first connecting adjacent standard panels together, then placing the sealing strip on the crests of the roofing panels. The sealing strip and the grooves on both sides of the crests must be aligned for them to engage. To ensure a proper engagement, it may be necessary to tap the sealing strip at various points to ensure a complete engagement between the sealing strip and the grooves. The overall construction process is complex, increasing construction costs. Utility Model Content

[0006] The purpose of this utility model is to provide a roofing panel that solves the problem of complex construction processes and operations leading to increased construction costs, simplifies the construction process, improves construction efficiency, and reduces waterproofing risks to extend the service life of tool sheds.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a roof panel, comprising several panels distributed on the left and right, wherein a first connecting part is provided on one side of the panel and a second connecting part is provided on the other side, the first connecting part and the second connecting part of adjacent panels are fastened together, and a drainage cavity is formed after the first connecting part and the second connecting part are fastened together, and a first water-blocking strip is provided on the lower side of the drainage cavity to prevent rainwater from flowing out of the drainage cavity to the bottom of the panel.

[0008] After adopting the above technical solution, this utility model has the following advantages: When building the roof panel onto the top wall of the tool shed, several panels are connected together by a snap-fit ​​method. During the construction process, one panel is fixed first, and the second connecting part is snapped together with the first connecting part to realize the installation of the roof panel, which simplifies the installation steps and improves construction efficiency. After the first connecting part and the second connecting part are snapped together, the first connecting part and the second connecting part form a drainage cavity. The first water-blocking strip in the drainage cavity prevents rainwater from seeping into the tool shed from the right side of the first connecting part, which plays a waterproof role while simplifying the construction process. Through the setting of the first water-blocking strip, even if rainwater seeps into the drainage cavity, the speed at which the rainwater flows along the drainage cavity to the eaves is greater than the speed at which the rainwater crosses the first water-blocking strip, thus preventing rainwater from entering the house from the drainage cavity.

[0009] Furthermore, the first connecting portion includes a first connecting panel and a second water-blocking strip. The second water-blocking strip is disposed on the side of the first connecting panel away from the plate body, and the first water-blocking strip is located between the second water-blocking strip and the plate body to divide the first connecting panel into multiple drainage zones.

[0010] By adopting the aforementioned technical solution, the setting of the first connecting panel and the second water-blocking strip increases the obstruction on the path of rainwater flowing to the lower side of the first connecting panel. That is, when rainwater enters the drainage chamber, in addition to the first water-blocking strip blocking it, the second water-blocking strip also blocks the rainwater on the right side of the first connecting panel, further preventing rainwater from seeping into the house, thereby improving the waterproof effect of the roof panel.

[0011] Furthermore, the top wall of the first water-blocking strip is provided with a water-blocking return section, which is located on the side of the first water-blocking strip opposite to the second water-blocking strip and extends to return the rainwater flowing towards the second water-blocking strip.

[0012] By adopting the aforementioned technical solution, a water-blocking return section is set on the top wall of the first water-blocking strip. When a large amount of water accumulates in the drainage area on the left side of the first water-blocking strip, the water-blocking return section at the top of the first water-blocking strip causes the rainwater flowing to the drainage area on the right side of the first water-blocking strip to flow back to the drainage area on the left side of the first water-blocking strip, reducing the amount of rainwater seeping into the drainage area on the right side of the first water-blocking strip, and further reducing the possibility of rainwater entering the house from the second water-blocking strip.

[0013] Furthermore, the first connecting portion includes a fastening protrusion on one side of the second panel opposite to the second connecting portion, the fastening protrusion fastening with the second connecting portion to connect adjacent panels.

[0014] When the aforementioned technical solution is adopted, the second connecting part is fastened to the fastening protrusion when two adjacent plates are connected, so as to prevent the second connecting part from separating from the fastening protrusion during deformation. By fastening the second connecting part to the fastening protrusion, the installation steps of the plate are simplified, thereby improving the installation efficiency of the plate.

[0015] Furthermore, the second connecting part includes a second connecting panel and an abutting fastening part. The drainage cavity is formed by adjacent plates, the first connecting part, the second connecting panel and the second water-blocking strip. The abutting fastening part is located on the left side of the second connecting panel and is fastened to the fastening protrusion.

[0016] When the second connecting part is connected to the snap-fit ​​rib, the second connecting panel covers the first connecting panel. Then, by setting the snap-fit ​​part to snap-fit ​​with the snap-fit ​​rib, the gap between the two adjacent panels is reduced, and the waterproof effect is improved.

[0017] Furthermore, the abutting and fastening part includes an abutting part and a fastening part. The abutting part extends toward the first panel, and the fastening part is located at the lower end of the abutting part. The fastening part extends below the fastening protrusion, and the abutting part abuts against the fastening protrusion.

[0018] When the aforementioned technical solution is adopted, the fastening part and the fastening protrusion are fastened together. The fastening part is located below the second connecting panel under the connection of the fastening part, which makes it easy for the fastening part to extend into the lower part of the fastening protrusion and fasten with the fastening protrusion. This improves the ease of installation between adjacent panels. At the same time, the bending design of the fastening part and the fastening part increases the path between the second connecting part and the fastening protrusion, reducing the possibility of rainwater entering the drainage cavity and playing a certain role in waterproofing.

[0019] Furthermore, the abutting part has a first abutting surface, and the right side of the fastening rib is a second abutting surface, with the first abutting surface abutting against the second abutting surface.

[0020] By adopting the aforementioned technical solution, when the abutting part abuts against the interlocking rib, the surface-to-surface contact between the first abutting surface and the second abutting surface further reduces the existence of gaps, thereby improving the waterproof effect.

[0021] Furthermore, the upper side of the fastening part is a waterproof slope, with the right side of the waterproof slope being lower than the left side to prevent rainwater from entering the drainage cavity.

[0022] By adopting the aforementioned technical solution, after rainwater enters through the abutment part and the snap-fit ​​rib, the setting of the waterproof slope reduces the possibility of rainwater entering the drainage cavity, thereby preventing rainwater from entering the house after passing through the first and second water-blocking strips.

[0023] Furthermore, the upper side of the fastening part is provided with a protrusion, which is located on the left side of the fastening part so that a drainage groove is formed between the abutting part and the protrusion. The upper side of the protrusion abuts against the lower side of the fastening rib.

[0024] Using the aforementioned technical solution, after the fastening part is fastened below the fastening rib, a drainage groove is formed between the protrusion and the abutment part, allowing rainwater entering the gap between adjacent panels to be discharged through the drainage groove, reducing the possibility of rainwater seeping into the house after entering the drainage chamber from the gap, and further improving the waterproof effect; in the drainage groove, the rainwater abuts against the lower side of the protrusion and the fastening rib, reducing the gap, and thus reducing the possibility of rainwater in the drainage groove entering the drainage chamber.

[0025] Furthermore, multiple of the first water-blocking strips are distributed on the first connecting panel.

[0026] By adopting the aforementioned technical solution, multiple first water-blocking strips divide the drainage chamber into multiple drainage zones distributed to the left and right, increasing the difficulty for rainwater to come into contact with the second water-blocking strips, thereby improving the waterproof effect.

[0040] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0041] like Figure 1 and Figure 2As shown, this utility model provides a roof panel, comprising a plurality of panels distributed left and right. In this embodiment, each panel includes a first panel 1 and a second panel 2. A first connecting portion 3 is provided on the same side of the first panel 1 and the second panel 2, and a second connecting portion 4 is provided on the other side of the second panel 2. The first connecting portion 3 and the second connecting portion 4 are respectively located on the left and right sides of the panel. Figure 2 , Figure 3 and Figure 5 As shown, the first connecting part 3 and the second connecting part 4 of adjacent plates are fastened together; when installing and fixing the plates, the plates distributed from left to right are respectively defined as the first plate, the second plate, the third plate, the fourth plate, etc., as follows. Figure 2 As shown, first, the first plate is fixed to the roof beam. After fixing the first connecting part 3 of the first plate with screws 5, the second connecting part 4 of the second plate is fastened to the first connecting part 3 of the first plate. Specifically, the fastening operation is as follows: Figure 2 As shown, the end of the second plate that is fastened to the first plate is tilted downwards and inserted into the first connecting part 3, with the right side higher than the left. Then, the other end of the second plate is pressed down, and the first connecting part 3 of the second plate is fixed with screws 5. The remaining plates are then operated in sequence to complete the installation of the roof panel. Figure 3 As shown, after installation, the upper sides of the first plate and the second plate are basically flush. Compared with the prior art, the installation steps are simple. After installation by screws 5, the distance between adjacent screws 5 is fixed, making it difficult for the first connecting part 3 and the second connecting part 4 to separate.

[0042] In another embodiment, the plate may consist of only a first panel 1 or a second panel 2. When it consists of only a first panel 1, a support column 12 is provided on the lower side of the first panel 1. When the plate is used to build a tool hut, the support column 12 is supported on a crossbeam to improve the stability of the plate after construction. The first connecting part 3 and the second connecting part 4 are respectively provided on the left and right sides of the plate. The first panel 1 and the second panel 2 may also be integrally formed solid plates. The integral structure can enhance the strength of the plate.

[0043] To further enhance the waterproof effect, such as Figure 5 and Figure 6As shown, the first connecting part 3 and the second connecting part 4 are fastened together to form a drainage cavity 6. The outlet of the drainage cavity 6 is located at the bottom and is open to allow rainwater accumulated in the drainage cavity 6 to flow out. The lower side of the drainage cavity 6 is provided with a first water-blocking strip 61 to prevent rainwater from flowing out of the drainage cavity 6 to the bottom of the panel. When rainwater enters the drainage cavity 6, the first water-blocking strip 61 prevents rainwater from seeping into the drainage cavity 6. The first water-blocking strip 61 prevents rainwater from flowing along the drainage cavity 6 towards the eaves at a speed greater than the speed at which the rainwater flows over the first water-blocking strip 61, thus preventing rainwater from entering the house from the drainage cavity 6. In this embodiment, multiple first water-blocking strips 61 can be distributed in the left-right direction to divide the drainage cavity 6 into multiple drainage areas, increasing the difficulty of rainwater flowing from left to right, thereby reducing the possibility of rainwater seeping into the house.

[0044] To further improve the waterproof effect, such as Figure 5 and Figure 6 As shown, the first connecting part 3 includes a first connecting panel 31 and a second water-blocking strip 32. The first connecting panel 31 is located on the right side of the first panel 1, and the second water-blocking strip 32 is located on the side of the first connecting panel 31 away from the first panel 1. The first water-blocking strip 61 is located between the second water-blocking strip 32 and the first panel 1 so that the first connecting panel 31 is divided into a second drainage area and multiple first drainage areas. After rainwater enters the first drainage area, it is blocked by multiple first water-blocking strips 61, reducing the possibility of rainwater entering the second drainage area. Through the multiple waterproofing of the first water-blocking strip 61 and the second water-blocking strip 32, the waterproofing effect is further improved.

[0045] To improve the support strength when the first panel 1 and the second panel 2 are installed separately, such as Figure 1 and Figure 5 As shown, a supporting rib 11 is provided between the first panel 1 and the second panel 2. Multiple supporting ribs 11 are distributed along the left-right direction. The arrangement of the supporting ribs 11 significantly reduces the weight of the panel, facilitating its transport, construction, and handling, while also improving its supporting strength. Figure 5 and Figure 6 As shown, the first drainage zone forms a first drainage groove 62 between the supporting rib 11 and the first water-blocking strip 61 or between adjacent first water-blocking strips 61, and the second drainage zone forms a second drainage groove 63 between the first water-blocking strip 61 and the second water-blocking strip 32; the formation of the first drainage groove 62 and the second drainage groove 63 accumulates rainwater, reduces the infiltration rate of rainwater, and thus improves the waterproofing effect.

[0046] To further improve the waterproofing effect of the first water-blocking strip 61, such as Figure 6As shown, the top wall of the first water-blocking strip 61 is provided with a water-blocking return section 611. The water-blocking return section 611 is located on the side of the first water-blocking strip 61 facing away from the second water-blocking strip 32 and extends to return the rainwater flowing towards the second water-blocking strip 32. Specifically, the water-blocking return section 611 extends towards the first drainage channel 62. When the rainwater accumulated in the first drainage channel 62 wants to cross the first water-blocking strip 61, the water-blocking return section 611 at the top of the first water-blocking strip 61 causes the rainwater to flow back into the first drainage channel 62, reducing the possibility of rainwater entering the second drainage channel 63, thereby further improving the waterproof effect.

[0047] In another embodiment, when the first connecting part 3 and the second connecting part 4 are engaged and connected, as follows: Figures 2 to 6 As shown, the first connecting part 3 includes a fastening rib 33 provided on one side of the second panel 2 away from the second connecting part 4. The fastening rib 33 is located on the right side of the second panel 2. The second connecting part 4 includes a second connecting panel 41 and an abutting fastening part 42. The second connecting panel 41 is provided on the second panel 2 and located on the left side of the second panel 2. The abutting fastening part 42 is provided on the left side of the second connecting panel 41. Specifically, when fastening and connecting adjacent panels, the left end of the abutting fastening part 42 extends into the lower side wall of the fastening rib 33 and is fastened and connected with the fastening rib 33.

[0048] Specifically, the abutting and fastening part 42 includes an abutting part 421 and a fastening part 422. The abutting part 421 extends to the left side of the second connecting panel 41 and toward the first panel 1. The fastening part 422 is located below the abutting part 421. As the plate is installed, the fastening part 422 first extends below the fastening protrusion 33, and then, as the plate is fixed, the fastening part 422 and the fastening protrusion 33 fasten in the vertical direction. After the fastening part 422 is fastened, the abutting part 421 is close to the right side of the fastening protrusion 33, reducing the fastening protrusion. The gap between the rib 33 and the second connecting panel 41 reduces the possibility of rainwater seepage; the abutment part 421 can also abut against the right side of the snap-fit ​​rib 33, thereby stabilizing the installation of the two adjacent panels; specifically, the left side of the abutment part 421 is the first abutment surface, and the right side of the snap-fit ​​rib 33 is the second abutment surface. When the abutment part 421 abuts against the snap-fit ​​rib 33, the abutment effect is improved by the surface-to-surface contact of the first abutment surface and the second abutment surface, reducing the possibility of gaps after abutment, thereby improving the waterproof effect.

[0049] To further reduce rainwater infiltration into the drainage chamber 6, such as Figure 6 As shown, the upper side of the fastening part 422 is provided with a waterproof slope 4221. Specifically, the upper side of the fastening part 422 is inclined with the right side lower than the left side to prevent rainwater from entering the first drainage area from between the fastening part 422 and the fastening rib 33, thereby reducing the amount of water stored in the first drainage area and improving the waterproof effect.

[0050] In another embodiment, such as Figure 7As shown, the upper side of the fastening part 422 is provided with a protrusion 4222. The protrusion 4222 is located on the left side of the fastening part 422 so that a drainage groove 4223 is formed between the left side of the abutment part 421 and the protrusion 4222. The drainage groove 4223 stores the rainwater that enters between the adjacent plates and discharges it, reducing the possibility of rainwater entering the drainage chamber 6.

[0051] To further reduce the possibility of rainwater entering the drainage chamber 6, the upper side of the protrusion 4222 may abut against the lower side of the fastening rib 33, thereby reducing the possibility of rainwater entering the drainage channel 4223 entering the drainage chamber 6 between the protrusion 4222 and the fastening rib 33.

[0052] When fixing the plate with screw 5, screw 5 is threaded downwards from the bottom wall of the second drainage zone to the top beam of the tool shed, thus stabilizing the installation of the plate. To prevent screw 5 from shifting and becoming misaligned during fixing, as follows... Figure 8 As shown, the plate body is equipped with a positioning groove 631, which is located in the second drainage area. When the screw 5 fixes the plate body, the screw 5 is fixed along the positioning groove 631 to avoid the possibility that the screw 5 in the length direction of the plate body may be misaligned.

[0053] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
