DETAILED DESCRIPTION

[0027] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0028] With the advancement and development of science and technology, metal has become a widely used material in the construction industry, especially in the metal roofing industry. Metal steel roofs have become the choice of many users, and the waterproofness of metal roofs has a profound impact on metal roofs. Currently, the most common waterproofing measure is to apply a waterproof organic coating to the surface of the color-coated steel plates. However, adjacent color-coated steel plates are usually connected with fasteners such as bolts, rivets, or self-tapping screws. Exposed fasteners are prone to rust in the natural environment, which makes the color-coated steel plates in contact with the fasteners prone to oxidation and rust, causing roof leaks, affecting indoor production and life, and increasing maintenance costs. In addition, the metal roof set up in this way has poor wind-proof performance and is prone to wear and corrosion of adjacent color-coated steel plates due to expansion and contraction, which is not compatible with the service life of photovoltaics.

[0029] The roof panel assembly according to an embodiment of the present application is described below with reference to FIG. 1 to FIG. 4 .

[0030] Figure 1 shows a schematic diagram of the structure of a roof panel assembly according to an embodiment of the present application; Figure 2 shows a schematic diagram of the structure of a support plate of the roof panel assembly according to an embodiment of the present application. As shown in Figures 1 and 2, the roof panel assembly 10 includes: a first fastener 200, a waterproof membrane 300, and a plurality of support plates 100 arranged in a first direction. In the description of this application, "plurality" means two or more.

[0031] The two end areas of the support plate 100 in the first direction are respectively the first end area (and the second end area. The first direction is the left and right direction observed by the observer when observing Figures 1 and 2. Please refer to the schematic marking in Figure 2 for details, wherein the first end area is located in the right end area of ​​Figures 1 and 2, and the second end area is located in the left end area of ​​Figures 1 and 2. The first end area of ​​the support plate 100 has a connecting portion 110, and the second end area of ​​the support plate 100 overlaps the first end area of ​​the adjacent support plate 100 and covers the connecting portion 110 of the adjacent support plate 100. Exemplarily, the connecting portion 110 can extend horizontally, and the two side surfaces of the connecting portion 110 in the thickness direction are parallel to the first direction. The support plate 100 can be a thermoplastic polyolefin metal plate (fusion tile), but is not limited to this.

[0032] The first fasteners 200 connect the connecting portion 110 to the purlin 20, and the second end regions of the support plates 100 cover the corresponding first fasteners 200. The waterproof membrane 300 covers the multiple support plates 100 and the first fasteners 200, effectively preventing the first fasteners 200 from being exposed and exposed to the natural environment. This prevents the first fasteners 200 from rusting or falling off, thereby preventing roof leaks. Furthermore, compared to the organic coating method used in related technologies, the waterproof membrane provides physical waterproofing and corrosion resistance, preventing roof rust and leakage.

[0033] Figure 3 shows an enlarged view of the circled portion A in Figure 1 . For example, referring to Figures 2 and 3 , the first fastener 200 can pass through the support plate 100 and be fixedly connected to the purlin 20, thereby securely connecting the first end region of the support plate 100 to the purlin 20 and improving the overall wind-resistant resistance of the roof panel assembly 10. The first fastener 200 can be a countersunk nail. This allows the surface of the first fastener 200 to be substantially flush with the surface of the support plate 100, and the nail head of the first fastener 200 does not protrude from the surface of the support plate 100, thereby ensuring smooth installation of the roof panel assembly 10.

[0034] Optionally, the waterproof membrane 300 can be a thermoplastic polyolefin waterproof roll, which is a new type of waterproof roll made of thermoplastic polyolefin (TPO) synthetic resin that uses advanced polymerization technology to combine ethylene propylene rubber and polypropylene as the base material, and adds antioxidants, anti-aging agents, and softeners. Polyester fiber mesh cloth can be used as the internal reinforcement material to make an enhanced waterproof roll, which is a synthetic polymer waterproof roll waterproof product.

[0035] According to the roof panel assembly 10 of the embodiment of the present application, by providing a connection portion 110 at the first end region of the support plate 100 and using a first fastener 200 to connect the connection portion 110 to the purlin 20, the connection between the roof panel assembly 10 and the purlin 20 can be strengthened, thereby improving the wind resistance of the roof panel assembly 10. By having the waterproof membrane 300 cover the multiple support plates 100 and the first fastener 200, the waterproof membrane 300 can form a sealed waterproof structure, preventing the first fastener 200 from being exposed, thereby preventing rust on the first fastener 200 and the support plates 100, preventing water leakage in the roof panel assembly 10, and providing effective dust protection. In addition, the installation and construction of the roof panel assembly 10 is simpler and more convenient, with lower precision requirements for the purlin 20, and a wider range of applications.

[0036] In an optional embodiment, the dimension of the connecting portion 110 in the first direction is 14 mm to 16 mm (inclusive). Specifically, for example, when the dimension of the connecting portion 110 in the first direction is less than 14 mm, the distance between the first fastener 200 and the outer edge of the connecting portion 110 in the first direction is too small, affecting the structural strength of the connecting portion 110 and thus the connection reliability between the support plate 100 and the purlin 20. When the dimension of the connecting portion 110 in the first direction is greater than 16 mm, when the second end region of the support plate 100 overlaps the first end region of the adjacent support plate 100, the smoothness of the overlap is affected, and the overall weight of the roof panel assembly 10 is increased.

[0037] Thus, by setting the dimension of the connecting portion 110 in the first direction to 14 mm to 16 mm, the connection between the support plate 100 and the purlin 20 is securely connected while ensuring the smoothness of the overlap between two adjacent support plates 100, thereby reducing the overall weight of the shed panel assembly 10 and lowering costs. Furthermore, the dimension of the connecting portion 110 in the first direction can optionally be 15 mm, but is not limited thereto.

[0038] In one embodiment, as shown in Figures 1 and 3, the waterproof membrane 300 includes a plurality of waterproof segments 310 corresponding one-to-one to a plurality of support plates 100, and the two end areas of each waterproof segment 310 in the first direction are respectively a third end area corresponding to the first end area (for example, the right end area in Figures 1 and 2) and a fourth end area corresponding to the second end area (for example, the left end area in Figures 1 and 2), and the fourth end area of ​​the waterproof segment 310 has an excess portion 311 that exceeds the second end area of ​​the corresponding support plate 100, and the excess portion 311 overlaps the third end area of ​​the adjacent waterproof segment 310.

[0039] For example, the portion 311 of the fourth end region of a waterproof segment 310 that extends beyond the second end region of the corresponding support plate 100 can be connected to the third end region of the adjacent waterproof segment 310 using hot-air welding. In this way, after welding multiple waterproof segments 310, a complete waterproof membrane 300 can be formed, thereby preventing roof leaks. Hot-air welding involves using preheated compressed air or inert gas to heat plastic weldment and welding rods until they reach a viscous state, and then performing the welding under low pressure. For example, a climbing welding machine can be used to weld the extending portion to the third end region of the adjacent waterproof segment 310.

[0040] In this embodiment, by overlapping the protruding portion 311 with the third end region of the adjacent waterproof segment 310, the second end region of the support plate 100 can be stably overlapped with the first end region of the adjacent support plate 100 through the connection between the two adjacent waterproof segments 310. While ensuring that the structure of the roof panel assembly 10 is more stable and reliable, the two adjacent support plates 100 do not need to be directly connected, effectively reducing the difficulty of installation.

[0041] In an optional embodiment, the length of the protruding portion 311 in the first direction can be 80 mm to 100 mm (inclusive). This configuration ensures that the length of the protruding portion 311 in the first direction is reasonable, ensuring that the protruding portion 311 can effectively extend to the third end region of the adjacent waterproof segment 310 and stably overlap the third end region of the adjacent waterproof segment 310, thereby ensuring the waterproof performance of the waterproof membrane 300. Furthermore, the length of the protruding portion 311 in the first direction can be 90 mm, but is not limited to this.

[0042] In one optional embodiment, the overlap between the protruding portion 311 and the third end region of the adjacent waterproof segment 310 has a dimension in the first direction of 60 mm to 80 mm (inclusive). This provides a reasonable dimension in the first direction between the protruding portion 311 and the third end region of the adjacent waterproof segment 310, ensuring a high connection strength between the protruding portion 311 and the third end region of the adjacent waterproof segment 310, thereby effectively improving the long-term reliability of the entire roof panel assembly 10. Furthermore, the overlap between the protruding portion 311 and the third end region of the adjacent waterproof segment 310 can have a dimension in the first direction of 70 mm, but is not limited thereto.

[0043] In one embodiment, referring to Figures 1 and 2 , the first end region of each support plate 100 extends beyond the third end region of the corresponding waterproof segment 310. For example, the third end region of the waterproof segment 310 may be spaced apart from the second end region of the adjacent support plate 100 in the first direction, i.e., the second end region of the adjacent support plate 100 only covers the first end region of the support plate 100, but does not cover the third end region of the waterproof segment 310.

[0044] In this embodiment, by making the first end area of ​​the support plate 100 extend beyond the third end area of ​​the corresponding waterproof segment 310, the third end area of ​​the waterproof segment 310 can be avoided from being covered by the second end area of ​​the adjacent support plate 100. While ensuring a firm connection between the two adjacent waterproof segments 310, the overall length of the waterproof segment 310 can be reduced, thereby effectively reducing costs.

[0045] In one embodiment, each support plate 100 includes a peak portion 120 and a trough portion 130 periodically alternately arranged in a first direction, the peak portion 120 protrudes from the trough portion 130, and the connecting portion 110 is connected to the peak portion 120; the peak portion 120 of the second end region of each support plate 100 overlaps the peak portion 120 of the first end region of the adjacent support plate 100, and the trough portion 130 of the second end region of each support plate 100 overlaps the connecting portion 110 of the adjacent support plate 100.

[0046] For example, in the example of FIG2 , the support plate 100 includes four peaks 120 and three troughs 130. The peaks 120 may include a straight section and two inclined sections. For the two peaks 120 located in the middle, one end of the two inclined sections is connected to the ends of the straight section, and the other end of the two inclined sections is connected to two adjacent troughs 130. For the peaks 120 located in the second end region, one of the two inclined sections has one end connected to one end of the straight section and the other end connected to a trough 130. The other of the two inclined sections has one end connected to the other end of the straight section, and the other end of the inclined section is a free end. The fourth end region of the waterproof section 310 extends beyond the free end of the inclined section of the support plate 100. For the peaks 120 located in the first end region, one of the two inclined sections has one end connected to one end of the straight section and the other end connected to a trough 130. The third end region of the waterproof section 310 extends to the inclined section. One end of the other of the two inclined sections is connected to the other end of the straight section, and the other end of the inclined section is connected to the connecting portion 110. The trough portion 130 may extend horizontally.

[0047] In this embodiment, the overlap of the two wave crests 120 can play a limiting role to a certain extent, preventing the two adjacent support plates 100 from moving relative to each other in the first direction, thereby further improving the stability of the roof panel assembly 10.

[0048] FIG4 shows an enlarged view of the circled portion B in FIG1 . In one embodiment, as shown in FIG1 and FIG4 , the roof panel assembly 10 further includes a second fastener 400, which is used to connect the waterproof membrane 300 and the trough portion 130 to the purlin 20. For example, the second fastener 400 may penetrate the waterproof membrane 300 and the trough portion 130, respectively, and connect to the purlin 20. The second fastener 400 may be a bolt, a rivet, or a self-tapping screw, but is not limited thereto.

[0049] Therefore, by providing the second fastener 400 , the connection reliability between the support plate 100 and the purlin 20 can be further improved, thereby improving the wind-resistant capability of the roof panel assembly 10 .

[0050] In one embodiment, as shown in Figures 1 and 4 , the roof panel assembly 10 further includes a fastener cover sheet 500. The fastener cover sheet 500 is connected to the waterproof membrane 300 and covers the corresponding second fasteners 400. For example, the fastener cover sheet 500 can be secured to the waterproof membrane 300 using hot air welding. This effectively prevents the second fasteners 400 from being exposed and exposed to the elements, thereby preventing them from rusting or falling off, and thus preventing roof leaks. Furthermore, the fastener cover sheet 500 can be made of the same material as the waterproof membrane 300, for example, TPO, thereby reducing the number of materials used in the roof panel assembly 10.
