DETAILED DESCRIPTION

[0026] 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 disclosure. Therefore, the drawings and description are to be considered as illustrative in nature and not restrictive.

[0027] With the advancement and development of science and technology, metal roof designs have been widely adopted in the construction industry. However, large areas of metal roofs are currently unused, and the subsequent use of metal roofs requires high costs for renovation. Moreover, the installation of photovoltaic modules on traditional metal roofs requires drilling holes, which can easily cause significant leakage risks, potentially reducing the waterproof functionality of the original roof and shortening the roof's service life. The typical life cycle of photovoltaic modules is 25 years, but the service life of metal roofs is shorter than that of photovoltaic modules. After the metal roof expires, it needs to be refurbished and replaced. The installation and removal of photovoltaic modules during replacement is relatively complicated, and it will also affect production and life, resulting in high renovation costs.

[0028] The typical installation process for photovoltaic modules and metal roofs requires first installing the supports, then the photovoltaic framework, and finally mounting the photovoltaic panels on the framework. This not only increases the roof load but also leads to higher material and labor costs for installing the photovoltaic modules, reducing the economic benefits of photovoltaic roof structures and hindering their widespread adoption. Furthermore, the installation and operation of photovoltaic power stations increase the risk of metal roof leakage and accelerate the corrosion of metal roofs.

[0029] In order to solve the problems of high installation cost and inconvenience of photovoltaic roof structures in related technologies, the present disclosure provides a photovoltaic roof structure. The technical solution of the photovoltaic roof structure is described below with reference to the accompanying drawings.

[0030] Figure 1 is a schematic diagram of the overall photovoltaic roof structure according to an embodiment of the present disclosure. Figure 2 is a schematic diagram of the connection structure of adjacent photovoltaic panels according to an embodiment of the present disclosure. Figure 3 is a schematic diagram of the connection structure of adjacent photovoltaic modules according to an embodiment of the present disclosure. Figure 4 is a schematic diagram of the structure of a fused tile according to an embodiment of the present disclosure. Referring to Figures 1 to 4, an embodiment of the present disclosure provides a photovoltaic roof structure 100. The photovoltaic roof structure 100 may include a fused tile 10, a photovoltaic module 20, and a photovoltaic fixing assembly 30.

[0031] Specifically, the fusion tile 10 includes a support plate 11, which is provided with a plurality of wave peak structures 12 arranged at intervals along a first direction (e.g., the left-right direction in FIG. 1 ). A photovoltaic module 20 is provided on the fusion tile 10, and the wave peak structure 12 is used to support the photovoltaic module 20. The photovoltaic module 20 includes at least one photovoltaic panel 21, and a first overlap portion 211 is formed on both sides of the photovoltaic panel 21 along the first direction. The first overlap portion 211 extends out of the wave peak structure 12 and is suspended. A photovoltaic fixing assembly 30 is provided between adjacent wave peak structures 12 and is fixedly connected to the first overlap portion 211 of the photovoltaic panel 21.

[0032] As shown in Figure 4, for example, the support plate 11 arranges the peak structure 12 and the trough structure periodically at intervals along the first direction, the peak structure 12 protrudes from the trough structure, the cross-section of the peak structure 12 can be trapezoidal, and the peak structure 12 protrudes in the direction away from the roof. The photovoltaic component 20 is placed on the peak structure 12 of the support plate 11, and the photovoltaic component 20 is supported by the top of the peak structure 12.

[0033] As shown in Figures 2 and 3, illustratively, the photovoltaic assembly 20 includes at least one photovoltaic panel 21. Exemplarily, when there is one photovoltaic panel 21, the first overlap portions 211 on both sides of the photovoltaic panel 21 along the first direction are respectively connected and fixed to the photovoltaic fixing assembly 30. When there are two or more photovoltaic panels 21, the first overlap portions 211 of adjacent photovoltaic panels 21 can be connected and fixed through the same photovoltaic fixing assembly 30, and the first overlap portions 211 on both sides of the first direction of the photovoltaic assembly 20 composed of the photovoltaic panels 21 as a whole are connected and fixed through the photovoltaic fixing assembly 30. The first overlap portions 211 on one side of the photovoltaic panel 21 can be continuously arranged or the first overlap portions 211 can be arranged at the corresponding position of the photovoltaic fixing assembly 30. The specific number of photovoltaic panels 21 is not limited here and can be selected according to actual usage requirements.

[0034] As shown in Figure 1, photovoltaic fixing assemblies 30 are positioned between adjacent peak structures 12 and within the trough structure. Multiple photovoltaic fixing assemblies 30 can be positioned along the length of the trough structure as needed. The photovoltaic fixing assemblies 30 are used to securely connect the first overlapped portion 211 of the photovoltaic panel 21. The photovoltaic fixing assemblies 30 limit the freedom of the photovoltaic panel 21 in the first direction and press the photovoltaic panel 21 onto the peak structure 12, thereby achieving the installation and fixation of the photovoltaic panel 21. This reduces the number of intermediate photovoltaic frames, additional building accessories, and holes that damage the fusion tiles, thereby effectively reducing the risk of water leakage, simplifying the construction process, and effectively reducing construction costs.

[0035] The photovoltaic roof structure of the embodiment of the present disclosure is configured by arranging first overlapping portions 211 on both sides of the photovoltaic panel 21 along a first direction, the first overlapping portions 211 extending out of the crest structure 12 and being suspended in the air, and arranging photovoltaic fixing components 30 between adjacent crest structures 12. The photovoltaic fixing components 30 fix the first overlapping portions 211 of the photovoltaic panel 21, and the installation of the photovoltaic panel 21 does not damage the support plate 11, and the waterproof function of the fusion tile 10 is not reduced, thereby avoiding the installation of the photovoltaic panel 21 from reducing the life of the fusion tile 10 and reducing the installation cost of the photovoltaic panel 21.

[0036] As shown in Figures 2 and 3, in one embodiment, the photovoltaic mounting assembly 30 includes a first support platform 31 and a pressure plate 32. The first support platform 31 is positioned between adjacent wave crest structures 12 and is connected to the fusion tile 10 via hot air welding. The pressure plate 32 is positioned opposite the first support platform 31 and is connected to the first support platform 31 via a first fastener 33. A clamping portion 34 is formed between the clamping plate 32 and the first support platform 31 to clamp and secure the first overlap portion 211.

[0037] The first support platform 31 and the trough structure of the fusion tile 10 are hot-air welded. After the first support platform 31 and the fusion tile 10 are welded, the reliability of the connection between the first support platform 31 and the fusion tile 10 can be ensured, and there is no need to drill holes on the fusion tile for fixing, thereby avoiding roof leakage.

[0038] It should be noted that hot air welding is a method of using preheated compressed air or inert gas to heat plastic welding rods and welds so that they can reach a viscous state and perform welding under low pressure. In the embodiment of the present disclosure, by welding the first support platform 31 to the trough structure of the fusion tile 10, the firmness and reliability of the connection between the photovoltaic fixing assembly 30 and the support plate 11 can be ensured. Moreover, no physical damage will be caused to the fusion tile 10, water leakage will be eliminated from the source, and there is no need to add photovoltaic keels. The photovoltaic panels can be installed through the photovoltaic fixing assembly, which saves material costs and reduces later labor costs.

[0039] For example, when the photovoltaic fixing assembly 30 is located between adjacent photovoltaic panels 21, the first fastener 31 passes through the middle of the pressure plate 32, and two clamping parts 34 are formed between the areas of the pressure plate 32 on both sides of the first fastener 31 and the first support platform 31 below. The clamping parts 34 can be fixed to the adjacent photovoltaic panels 21 respectively, and the size of the first support platform 31 can be roughly consistent with the size of the trough structure.

[0040] For example, when the photovoltaic fixing assembly 30 is located on the side of the photovoltaic panel 21 on the outside of the photovoltaic assembly 20 as a whole, a clamping portion 34 can be formed between the pressure plate 32 and the first support platform 31, and the clamping portion 34 clamps and fixes the first overlapping portion 211 on the outside of the photovoltaic panel 21.

[0041] At least one photovoltaic fixing assembly 30 may be provided on both sides of the photovoltaic panel 21 in the first direction, and the specific number of the photovoltaic fixing assembly 30 is not limited herein.

[0042] As shown in Figure 2, in one embodiment, the photovoltaic fixing assembly 30 also includes a base plate 35, the base plate 35 includes a main body 351 and welding parts 352 located on both sides of the main body 351, the base plate 35 and the fusion tile 10 form a sealed cavity, the welding part 352 and the fusion tile 10 are welded by hot air, the first support platform 31 is located on the main body 351, the main body 351 and the first support platform 31 are connected by a second fastener 36, and the end of the second fastener 36 is located in the sealed cavity.

[0043] As shown in Figure 2, the second fastener 36 can, for example, be a bolt, self-tapping screw, or other fastening component. For example, in the disclosed embodiment, the second fastener 36 is a screw. The base plate 35 is generally arched, with the main body 351 forming a relief between the welded portions 352 on opposite sides. The screw secures the first support platform 31 to the main body 351 of the base plate 35, with the screw end cap located within the relief. After the base plate 35 is secured to the support plate by hot air welding, a sealed cavity is formed between the relief and the support plate 11.

[0044] The embodiment of the present disclosure connects and fixes the first support platform 31 to the fusion tile 10 by providing a bottom plate 35, so that there is no need to drill holes on the support plate 11 for fixing, and the second fastener 36 can also be hidden, effectively reducing the hidden danger of water leakage, improving the overall aesthetics, and reducing the risk of exposure of the second fastener 36. The bottom plate 35 is welded and fixed to the trough structure through the welding part 352 provided on the bottom plate 35, thereby reducing the area of ​​the welding area and reducing the difficulty of welding.

[0045] In one embodiment, the photovoltaic fixing assembly 30 further includes an elastic buffer layer (not shown in the figure), which is arranged on opposite sides of the first overlap portion 211 or on opposite sides of the pressure plate 32 and the first support platform 31 .

[0046] For example, the elastic buffer layer can be a rubber pad. By providing the rubber pads on opposite sides of the first overlap portion 211 or on opposite sides of the pressing plate 32 and the first support platform 31, the friction between the contact surface of the clamping portion 34 and the first overlap portion 211 can be increased, thereby enhancing the fastening effect and preventing damage to the first overlap portion 211 and the clamping portion 34 during fastening.

[0047] As shown in Figure 2, in one embodiment, the first fastener 33 includes a screw 331 and a locking nut 332. One end of the screw 331 passes through the first support platform 31 and is fixed through the top of the first support platform 31. The other end of the screw 331 passes through the pressure plate 32. The locking nut 332 is used to lock and fix the pressure plate 32. The pressure plate 32 slides relative to the screw 331 to adjust the size of the clamping part 34 to ensure the firm installation of the photovoltaic panel 21.

[0048] As shown in Figure 2, the first support platform 31 has an inner cavity. One end of the screw 331 extends into the inner cavity and is fixed to the inner wall surface of the top of the first support platform 31. The other end of the screw 331 passes through the pressure plate 32. The pressure plate 32 can be moved up and down along the screw 331 to adjust the distance from the outer wall surface of the top of the first support platform 31, thereby adjusting the size of the clamping portion 34. After the first overlapping portion 211 is inserted into the clamping portion 34, the locking nut 332 is slid downward to press the pressure plate 32 downward on the upper end surface of the first overlapping portion 211, thereby pressing and fixing the photovoltaic panel 21 and improving the wind resistance of the roof photovoltaic structure.

[0049] As shown in FIG3 , in one embodiment, the photovoltaic roof structure further includes an inspection channel 40 (not shown), which is located between adjacent photovoltaic modules 20. The inspection channel 40 is arranged along a second direction, which is perpendicular to the first direction. The second direction can be expressed as a direction perpendicular to the paper. For example, the inspection channel 40 can be a trough structure between two adjacent peak structures, so that an inspection channel can be formed between two adjacent groups of photovoltaic modules 20, making it easier for users to perform maintenance on each group of photovoltaic modules later.

[0050] As shown in Figures 2 and 3, in one embodiment, the fusion tile 10 also includes a waterproof membrane 13, and the support plate 11 includes a first surface and a second surface arranged opposite to each other, the first surface is in contact with the roof, and the waterproof membrane 13 is bonded to the second surface through an adhesive layer. The support plate 11, as the structural body of the fusion tile 10, can play a role in supporting the photovoltaic module 20. The second surface is the side of the fusion tile 10 that needs to be exposed, and the first surface is the side of the support plate 11 facing the inside of the building. In Figure 2, the first surface can represent the lower surface of the support plate 11, and the second surface can represent the upper surface of the support plate 11. The waterproof membrane 13 can be bonded to the second surface through or an adhesive layer (not shown in the figure), and the top surface of the fusion tile 10 has a top surface waterproof function.

[0051] In one embodiment, the support plate 11 is made of metal. The support plate 11 may be a metal plate, comprising a first surface and a second surface disposed opposite each other. The first surface and / or the second surface of the support plate 11 may be provided with a coating. The coating may provide good protection for the metal support plate 11 and enhance the corrosion resistance of the support plate 11.

[0052] In one embodiment, when the support plate 11 is a carbon steel substrate, the coating may be a zinc coating or an aluminum zinc coating. When the support plate 11 is an aluminum alloy or stainless steel, the coating may be an oxide layer on the surface of the aluminum alloy plate or the stainless steel.

[0053] For example, the support plate 11 may be a galvanized steel plate, an aluminum-plated steel plate, an aluminum-zinc-plated steel plate, a zinc alloy-plated steel plate, an aluminum plate, or a stainless steel plate. For example, the support plate 11 in the embodiment of the present disclosure is a galvanized steel plate.

[0054] In one embodiment, the waterproofing membrane 13 is made of thermoplastic polyolefins and polyvinyl chloride. The waterproofing membrane 13 can be made by polymerizing ethylene propylene rubber (EPR) and polypropylene to form a thermoplastic polyolefin synthetic resin base, with antioxidants and anti-aging agents added. The waterproofing membrane can also be reinforced with polyester fiber mesh.

[0055] It should be noted that the waterproof roll 13 may include, but is not limited to, a thermoplastic polyolefin waterproof roll or a polyester fiber reinforced polyvinyl chloride roll. The present disclosure does not limit the specific material of the waterproof roll, and can be set according to actual design and use requirements.

[0056] In one embodiment, the support plate 11 is made of metal, and the waterproof membrane 13 is made of a thermoplastic polyolefin waterproof membrane or a polyvinyl chloride waterproof membrane. For example, the fused tile 10 can be formed by combining the support plate 11 and the waterproof membrane 13, with the waterproof membrane 13 being bonded to the second surface of the support plate 11 via an adhesive structure.

[0057] As shown in Figure 1, in one embodiment, a support plate 11 is provided with multiple wave peak structures 12 arranged evenly spaced along a first direction, with each photovoltaic module 20 supported by an equal number of wave peak structures 12. The evenly spaced, periodic arrangement of wave peak structures 12 ensures consistent force distribution across the photovoltaic module, reducing the risk of localized damage. This ensures more uniform force distribution between the support plate and the photovoltaic module, enhancing the overall wind-uplift resistance of the photovoltaic roof structure.

[0058] For example, in the disclosed embodiment, a photovoltaic module 20 spans ten wave crest structures 12 along a first direction, and an access channel 40 is provided between two photovoltaic modules 20. In this case, the modular arrangement formed by the photovoltaic modules 20 and the fused tiles 10 maximizes the use of the roof area, improving the efficiency of the roof area, thereby increasing the luminous efficiency of the photovoltaic modules 20 and ensuring the maintenance of the photovoltaic modules 20. The modular arrangement of the photovoltaic modules 20 and the fused tiles 10 can be set according to actual usage requirements.

[0059] As shown in Figures 2 and 4, in one embodiment, the peak structure 12 includes a first side 121, a second side 123 and a top edge 122. The first side 121 and the second side 123 are inclined relative to the plane where the support plate 11 is located, and the top edge 122 is parallel to the plane where the support plate 11 is located. The top edge 122 connects the first side 121 and the second side 123, and the photovoltaic component 20 is supported by the top edge 122.

[0060] Exemplarily, the peak structure 12 can be roughly a trapezoidal structure, with one end of the first side 121 connected to the trough structure of the support plate 11, the other end of the first side 121 connected to one end of the top edge 122, one end of the second side 123 connected to the trough structure of the support plate 11, and the other end of the second side 123 connected to the other end of the top edge 122.

[0061] In one embodiment, the fused tile 10 further includes a first adhesive layer located at the top edge of the crest structure. A second adhesive layer is provided in the region where the photovoltaic module 20 supports and contacts the top edge 122 of the crest structure. The first adhesive layer and the second adhesive layer are bonded together. During installation of the photovoltaic module 20, the photovoltaic module 20 and the fused tile 10 can be roughly aligned using the first and second adhesive layers, and then pressed and secured using the photovoltaic fixing assembly 30, thereby preventing displacement during installation.

[0062] For example, the photovoltaic roof structure of the embodiments of the present disclosure can be applied to a photovoltaic building. The photovoltaic building can include a building structure and the photovoltaic roof structure of the embodiments of the present disclosure, with the photovoltaic roof structure installed on the building structure. For example, the photovoltaic building can be a photovoltaic curtain wall or a photovoltaic canopy.
