[0025] 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.

[0026] 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 preferred choice of many users, and the waterproof performance of metal roofs has a profound impact on metal roofing. Currently, a common waterproofing measure is to apply a waterproof organic coating to the surface of the color-coated steel sheets. However, adjacent color-coated steel sheets are usually connected with fasteners such as bolts, rivets, or self-tapping screws. Exposed fasteners are prone to rust in the natural environment, which in turn makes the color-coated steel sheets in contact with the fasteners susceptible to oxidation and rust. In addition, the color-coated steel sheets expand and contract with changes in the natural temperature, causing the nail holes in the color-coated steel sheets to become larger and larger, resulting in roof leaks, affecting indoor production and life, and increasing maintenance costs.

[0027] FIG1 is a schematic structural diagram of a roof panel assembly according to an embodiment of the present disclosure. As shown in FIG1 , the roof panel assembly 10 includes a support plate 100 , a fastener 200 , and a fastener cover sheet 300 .

[0028] Specifically, the support panel 100 includes troughs 140 and crests 130 periodically spaced in a first direction (e.g., left-right in FIG. 1 ), with the crests 130 protruding from the troughs 140. Fasteners 200 are used to securely connect the troughs 140 to the purlins 20, thereby enhancing the wind-resistant properties of the roof panel assembly 10. A fastener cover sheet 300 is secured to the side of the troughs 140 facing away from the purlins 20, and covers the fasteners 200.

[0029] For example, the crests 130 have a generally trapezoidal structure. Each crest 130 may include a straight section and two oppositely disposed inclined sections. One end of each inclined section is connected to the straight section and the other end is connected to the trough 140. Each trough 140 may extend horizontally, i.e., both sides of the trough 140 in the thickness direction may be parallel to the first direction. Fasteners 200 may pass through the support plate 100 and be fixedly connected to the purlin 20.

[0030] For example, the fastener 200 may be a bolt, a rivet, or a self-tapping screw. The fastener cover sheet 300 may be made of a thermoplastic polyolefin material, i.e., a new waterproof material made from a thermoplastic polyolefin (TPO) synthetic resin that combines ethylene propylene rubber and polypropylene using advanced polymerization technology, with antioxidants, anti-aging agents, and softeners added. A reinforced waterproof material may be made by using polyester fiber mesh as internal reinforcement, and is a synthetic polymer waterproof material.

[0031] According to the roof panel assembly 10 of the disclosed embodiment, by fixing and connecting the fastener cover sheet 300 to the surface of the trough portion 140 facing away from the purlin 20, and by covering the fastener 200 with the fastener cover sheet 300, the fastener 200 or the connection hole can be effectively prevented from being exposed, thereby protecting the fastener 200 from contact with the natural environment. This can prevent the fastener 200 from rusting or falling off, prevent roof leaks, ensure normal indoor production and life, and reduce maintenance costs. In addition, because the trough portion 140 is relatively flat, the connection between the fastener cover sheet 300 and the support plate 100 is simpler and more convenient, thereby improving the installation efficiency of the roof panel assembly 10.

[0032] In one embodiment, the thickness of the edge region of the fastener covering sheet 300 is less than the thickness of the middle region of the fastener covering sheet 300. For example, the edge region of the fastener covering sheet 300 may be fixedly connected to the trough portion 140. The middle region of the fastener covering sheet 300 is disposed opposite the fastener 200, and the middle region of the fastener 200 may further protrude beyond the edge region of the fastener 200.

[0033] It should be noted that the “central region” in this application should be understood in a broad sense, referring to the region located within the edge region of the fastener covering sheet 300 , and is not limited to the central region of the fastener covering sheet 300 .

[0034] In this embodiment, the thickness of the edge area of ​​the fastener covering sheet 300 is less than the thickness of the middle area of ​​the fastener covering sheet 300. The middle area of ​​the fastener covering sheet 300 has a higher structural strength than the edge area, can withstand a larger load, and is not easy to be damaged, thereby better protecting the fastener 200, preventing external impurities such as rainwater and dust from entering the room, and ensuring normal production and life indoors.

[0035] In one embodiment, the edge region of the fastener cover sheet 300 is connected to the trough portion 140, and the portion of the edge region of the fastener cover sheet 300 connected to the trough portion 140 forms a closed pattern. For example, the edge region of the fastener cover sheet 300 and the trough portion 140 can be connected using hot air welding. Hot air welding uses preheated compressed air or inert gas to heat the plastic weldment and welding rod until they become viscous, and then performs welding under low pressure.

[0036] Therefore, by making the portion of the edge area of ​​the fastener covering sheet 300 connected to the trough portion 140 form a closed figure, a closed space for protecting the fastener 200 can be defined between the fastener covering sheet 300 and the trough portion 140, thereby preventing rainwater and impurities such as dust in the external natural environment from entering the room through the gap between the fastener covering sheet 300 and the trough portion 140, further ensuring that the fastener covering sheet 300 has good waterproof and dustproof properties, ensuring normal production and life indoors.

[0037] In an optional embodiment, the outer contour of the fastener cover sheet 300 can be circular, and the diameter of the fastener cover sheet 300 can be 118 mm to 122 mm (inclusive). Specifically, for example, if the diameter of the fastener cover sheet 300 is less than 118 mm, the diameter of the fastener cover sheet 300 is too small, which may result in a small connection area between the edge area of ​​the fastener cover sheet 300 and the trough portion 140, affecting the connection strength between the fastener cover sheet 300 and the trough portion 140. If the diameter of the fastener cover sheet 300 is greater than 122 mm, the diameter of the fastener cover sheet 300 is too large, which may result in a waste of cost.

[0038] Thus, by setting the diameter of the fastener cover sheet 300 to 118 mm to 122 mm, a reasonable diameter of the fastener cover sheet 300 can ensure a high connection strength between the fastener cover sheet 300 and the trough portion 140, thereby effectively protecting the fastener 200 from corrosion and reducing costs. Furthermore, the diameter of the fastener cover sheet 300 can optionally be 120 mm, but is not limited thereto.

[0039] In one embodiment, referring to FIG. 1 , a support panel 100 may include a support layer 110 and a waterproof layer 120. The waterproof layer 120 is disposed on a side of the support layer 110 facing away from the purlin 20. A fastener cover sheet 300 is fixedly connected to a surface of the waterproof layer 120 in the trough portion 140 facing away from the support layer 110. For example, the shape of the waterproof layer 120 may be adapted to the shape of the support layer 110. The support layer 110 may be a thermoplastic polyolefin metal sheet (fused tile). The material of the waterproof layer 120 may be the same as that of the fastener cover sheet 300, for example, TPO, thereby reducing the number of materials used in the roof panel assembly 10. In other embodiments, the support panel 100 may be a fused tile, wherein the support layer 110 is a metal sheet and the waterproof layer 120 is a thermoplastic polyolefin layer.

[0040] Thus, by ensuring that the support plate 100 includes a support layer 110 and a waterproof layer 120, the support layer 110 provides support, effectively ensuring the structural strength of the roof panel assembly 10 and protecting the roof panel assembly 10 from damage due to external forces. The waterproof layer 120 forms a sealed, waterproof structure with the fastener cover sheet 300, effectively preventing corrosion of the fasteners 200 and the support layer 110, thereby preventing water leakage from the roof panel assembly 10. Furthermore, compared to the organic coating method used in related art, the waterproof layer 120 provides physical waterproofing and corrosion resistance, preventing roof corrosion and leakage.

[0041] In one embodiment, a plurality of support plates 100 are arranged in a first direction. The support layer 110 of each support plate 100 has two end regions in the first direction, namely a first end region and a second end region. The waterproof layer 120 of each support plate 100 has two end regions in the first direction, namely a third end region corresponding to the first end region and a fourth end region corresponding to the second end region. The fourth end region of the waterproof layer 120 has a portion 121 that extends beyond the second end region of the corresponding support layer 110, and the portion 121 overlaps the third end region of the adjacent waterproof layer 120. In this application, "plurality" means two or more. For example, the portion 121 of the fourth end region of the waterproof layer 120 that extends beyond the second end region of the corresponding support layer 110 can be connected to the third end region of the adjacent waterproof layer 120 using hot air welding. In this way, after welding, the multiple waterproof layers 120 form a complete waterproof structure, thereby preventing roof leaks.

[0042] In this embodiment, by overlapping the protruding portion 121 with the third end region of the adjacent waterproof layer 120, the second end region of the supporting layer 110 can be stably overlapped with the first end region of the adjacent supporting layer 110 through the connection between the two adjacent waterproof layers 120. While ensuring that the structure of the roof panel assembly 10 is more stable and reliable, the two adjacent supporting layers 110 do not need to be directly connected, thereby effectively reducing the difficulty of installation.

[0043] In one embodiment, a portion of the protruding portion 121 overlaps the waterproof layer 120 of the crest portion 130 of the adjacent support plate 100, and another portion of the protruding portion 121 overlaps the waterproof layer 120 of the trough portion 140 of the adjacent support plate 100 (not shown). For example, a portion of the protruding portion 121 may overlap the waterproof layer 120 of the inclined section of the crest portion 130 of the adjacent support plate 100, and another portion of the protruding portion 121 may be connected to the waterproof layer 120 of the trough portion 140 connected to the inclined section.

[0044] Therefore, through the above arrangement, the protruding portion 121 can overlap the crest portion 130 and the trough portion 140 of the adjacent support plate 100 at the same time, thereby increasing the connection area of ​​the two adjacent support plates 100 and making the structure of the roof panel assembly 10 more stable and reliable.

[0045] In one embodiment, the area of ​​another portion of the protruding portion 121 is larger than the area of ​​one portion of the protruding portion 121. In other words, the area of ​​the waterproof layer 120 of the protruding portion 121 overlapping the trough 140 of the adjacent support panel 100 is larger than the area of ​​the waterproof layer 120 of the protruding portion 121 overlapping the crest 130 of the adjacent support panel 100. Therefore, because the trough 140 is relatively flat, the connection between the protruding portion 121 and the waterproof layer 120 of the trough 140 of the adjacent support panel 100 is simpler and more convenient, and the adjacent waterproof layers 120 are more securely fixed, thereby improving the long-term reliability of the roof panel assembly 10.

[0046] In one embodiment, the other portion of the protruding portion 121 can have a dimension in the first direction of 60 mm to 80 mm (inclusive). This provides a reasonable dimension in the first direction for the other portion of the protruding portion 121, ensuring a high connection strength between the protruding portion 121 and the third end region of the adjacent waterproof layer 120, thereby further improving the long-term reliability of the roof panel assembly 10. Alternatively, the other portion of the protruding portion 121 can have a dimension in the first direction of 70 mm, but is not limited thereto.

[0047] In one embodiment, the minimum distance between the fastener 200 and two adjacent crests 130 is equal. In this way, the fastener 200 can be located at the center of the trough 140 in the first direction, thereby making the force applied to the support plate 100 more uniform and improving the overall wind-resistant ability of the roof panel assembly 10.
