Description

Technical Field

[0001] This application belongs to the field of photovoltaic technology, specifically relating to a metal roofing panel. Background Technology

[0002] To improve construction efficiency, reduce construction costs, and increase power generation efficiency in photovoltaic (PV) buildings, wide-panel PV modules are increasingly being used. Because wide-panel PV modules have a wider span, the corresponding width of the metal roof panels supporting them is also correspondingly wider. To enhance the wind uplift resistance of the PV modules, intermediate support sections are typically installed on the metal roof panels. By bonding the PV modules to these intermediate support sections and fixing them to the roof purlins using intermediate brackets, the wind uplift resistance of both the PV modules and the metal roof panels can be improved.

[0003] In existing technologies, the bottom of the intermediate support section of metal roof panels is typically equipped with a snap-fit ​​groove for connecting to the intermediate support. The snap-fit ​​groove can be installed on the intermediate support by forced clamping from both sides, making the installation of metal roof panels quite difficult. Moreover, during the process of pressing the snap-fit ​​groove onto the intermediate support, damage or deformation of the snap-fit ​​groove or the intermediate support can easily occur, greatly increasing the risk of water leakage from the metal roof panel and reducing its wind uplift resistance. Summary of the Invention

[0004] This application aims to provide a metal roofing panel to solve the problems of high water leakage risk and low wind uplift resistance of existing metal roofing panels.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] This application discloses a metal roofing panel, which includes: a plurality of base plates and a first overlapping portion disposed between the base plates; wherein...

[0007] The first overlapping portion protrudes from the base plate portion, and the top of the first overlapping portion is used to overlap with the photovoltaic module;

[0008] The first overlapping portion and the two adjacent base plate portions form an installation groove, and a first fastening portion is provided on one side of the installation groove.

[0009] Optionally, the number of mounting slots is at least two, and the first fastening portions of two adjacent mounting slots are symmetrically arranged with respect to the base plate portion between them.

[0010] Optionally, the base plate portion and the first overlapping portion are arranged sequentially along the first direction of the metal roof panel;

[0011] The first fastening part protrudes from one side of the mounting groove.

[0012] Optionally, the number of mounting slots is an even number;

[0013] Along the first direction, the mounting grooves are combined in pairs to form a mounting groove group, and in the two mounting grooves that make up the mounting groove group, the protruding directions of the first fastening part are either far apart or close to each other.

[0014] Optionally, the dimension of the mounting groove in the first direction is greater than the dimension of the intermediate support in the first direction.

[0015] Optionally, the mounting slot further includes: a first extension, a second extension, and a third extension; wherein,

[0016] The first extension extends from one of the two adjacent base plate portions to the first overlap portion;

[0017] The second extension extends from one of the two adjacent base plate portions to the first fastening portion;

[0018] The third extension extends from the first overlapping portion to the first fastening portion;

[0019] The first extension, the first overlapping portion, the third extension, the first fastening portion, and the second extension together form the mounting groove.

[0020] Optionally, the first fastening portion is parallel to the base plate portion.

[0021] Optionally, the first extension portion is inclined relative to the second extension portion and the third extension portion, respectively.

[0022] Optionally, the included angles between the second extension and the first fastening portion, and between the third extension and the first fastening portion, are all acute angles. Optionally, the metal roof panel further includes: a second overlapping portion disposed at the edge of the metal roof panel, the height of the second overlapping portion being flush with the height of the first overlapping portion.

[0023] In this embodiment, the first overlapping portion of the metal roof panel and two adjacent bottom plate portions can be enclosed to form an installation groove for installing an intermediate support. Since a first fastening portion is provided on one side of the installation groove, this first fastening portion can be used to fasten with the intermediate support. During the installation of the installation groove to the intermediate support, only the first fastening portion on one side of the installation groove needs to be fastened to the intermediate support, avoiding the forced pressing of the installation groove to both sides of the intermediate support. This not only reduces the installation difficulty between the intermediate support and the metal roof panel, but also avoids damage or deformation to the installation groove of the metal roof panel and the intermediate support, thereby reducing the risk of water seepage in the metal roof panel and improving its wind resistance.

[0037] Reference Figure 1The diagram shows a structural schematic of a metal roofing panel according to an embodiment of this application. Figure 2 , showed Figure 1 The structural schematic diagram of the metal roof panel at location A is shown below. Figure 3 This illustrates one application of the present application. Figure 1 The schematic diagram of the photovoltaic roofing system with metal roof panels shown is for reference. Figure 4 , showed Figure 3 The diagram shows another structural view of the photovoltaic roof system, for reference. Figure 5 , showed Figure 3 The schematic diagram of the intermediate support of the photovoltaic roof system shown is for reference. Figure 6 , showed Figure 3 The diagram shows the structural schematic of the boat-shaped support for the photovoltaic roofing system.

[0038] Specifically, the metal roof panel 10 includes: a plurality of base plate portions 101 and a first overlapping portion 102 disposed between the base plate portions 101; wherein, the first overlapping portion 102 protrudes from the base plate portion 101, and the top of the first overlapping portion 102 can be used to overlap with the photovoltaic module 12; the first overlapping portion 102 and two adjacent base plate portions 101 enclose to form an installation groove 103, and a first fastening portion 104 is provided on one side of the installation groove 103.

[0039] In this embodiment, the first overlapping portion 102 of the metal roof panel 10 and two adjacent bottom plate portions 101 can be enclosed to form a mounting groove 103 for installing the intermediate support 11. Since a first fastening portion 104 is provided on one side of the mounting groove 103, the first fastening portion 104 can be used to fasten with the intermediate support 11. During the installation of the mounting groove 103 to the intermediate support 11, only the first fastening portion 104 on one side of the mounting groove 103 needs to be fastened to the intermediate support 11, avoiding the operation of forcibly pressing the mounting groove 103 to both sides of the intermediate support 11. This not only reduces the installation difficulty between the intermediate support 11 and the metal roof panel 10, but also avoids damage or deformation to the mounting groove 103 and the intermediate support 11 of the metal roof panel 10, thereby reducing the risk of water seepage in the metal roof panel 10 and improving its wind resistance.

[0040] Specifically, the metal roof panel 10 can serve as the roof panel of a photovoltaic building. The metal roof panel 10 can be made of profiled steel sheets or similar materials to achieve good strength. The metal roof panel 10 can be fixed to the purlins of the building structure via intermediate supports 11 and boat-shaped supports 13, thus connecting the metal roof panel 10 to the building structure. Photovoltaic modules 12 can be bonded to the top of the metal roof panel 10 using structural adhesives or other bonding agents to form a photovoltaic building.

[0041] Optionally, the two sides of the metal roof panel 10 may also be provided with a second overlapping portion 105, which protrudes from the bottom plate portion 101; the photovoltaic roof system may also include: a boat-shaped support 13, which is fastened to the second overlapping portion 105; and a photovoltaic module 12 connected to the second overlapping portion 105.

[0042] In practical applications, the first overlap 102 can be located in the middle region of the metal roof panel 10, and the second overlap 105 can be located in the edge region of the metal roof panel 10. The position corresponding to the first overlap 102 can be connected to the purlin via an intermediate support 11, and the position corresponding to the second overlap 105 can be connected to the purlin via a boat-shaped support 13. In this way, by connecting the middle region and the edge region of the metal roof panel 10 to the purlin respectively, the connection strength of the metal roof panel 10 to the building structure can be improved, thereby improving the wind uplift resistance of the metal roof panel 10.

[0043] For example, the intermediate support 11 and the boat-shaped support 13 can be connected to the purlin first using fasteners such as bolts. Then, the mounting groove 103 of the metal roof panel 10 is fitted into the intermediate support 11, and the second fastening part 111 is fastened to the first fastening part 104. The second overlap parts 105 of the edges of two adjacent metal roof panels 10 are locked together using the hooks of the boat-shaped support 13 to connect the metal roof panels 10 to the building body.

[0044] Specifically, the heights of the first overlapping portion 102 and the second overlapping portion 105 can be set at the same level so that the photovoltaic module 12 can be simultaneously overlapped and bonded to the first overlapping portion 102 and the second overlapping portion 105, thereby improving the connection strength between the photovoltaic module 12 and the metal roof panel 10, and thus improving the wind resistance of the photovoltaic module 12.

[0045] In this embodiment, since the mounting groove 103 of the metal roof panel 10 has a first fastening part 104 on only one side, and the intermediate support 11 has a second fastening part 111 on only one side, the installation process of the metal roof panel 10 onto the intermediate support 11 only requires fastening the mounting groove 103 onto the intermediate support 11 and fastening the first fastening part 104 from one side to the second fastening part 111. This reduces installation difficulty and avoids damage or deformation to the metal roof panel 10 and the intermediate support 11, thereby reducing the risk of water seepage in the photovoltaic roof system and improving its wind uplift resistance. In specific applications, when the risk of water seepage in the metal roof panel 10 is low and its wind uplift resistance is strong, it is convenient to install wide photovoltaic modules 12 on the metal roof panel 10; that is, the width of the photovoltaic modules 12 can be relatively wide. Therefore, the installation and construction efficiency of the photovoltaic module 12 can be relatively high, the power generation efficiency can be relatively high, the gaps between the photovoltaic modules 12 can be relatively small, the installation efficiency can be relatively high, and the overall power generation of the photovoltaic roof system can be relatively high.

[0046] like Figure 1 As shown, the number of mounting slots 103 can be at least two, and the first fastening portions 104 of two adjacent mounting slots 103 are symmetrically arranged with respect to the base plate portion 101 between them.

[0047] In practical applications, when the first fastening portions 104 of two adjacent mounting slots 103 are symmetrically arranged relative to the base plate portion 101 between them, the fastening directions of the two intermediate supports 11 on both sides of the same base plate portion 101 can be opposite, making the connection method simpler. This not only reduces the types of components used to connect the intermediate supports 11 in the photovoltaic roofing system, facilitating standardized component management, but also ensures more even stress distribution on the mounting slots 103 on both sides of the base plate portion 101, further preventing damage to the metal roof panel 10 and improving the connection reliability between the metal roof panel 10 and the intermediate supports 11.

[0048] For example, such as Figure 1 As shown, the first fastening part 104 of the mounting groove 103 on the left side of the middle base plate 101 is located on the left, and the first fastening part 104 of the mounting groove 103 on the right side of the middle base plate 101 is located on the right. That is, the first fastening parts 104 on both sides of the middle base plate 101 are symmetrically arranged relative to the base plate 101. During the process of fastening the metal roof panel 10 to the intermediate support 11, the mounting groove 103 on the left can be fastened to the left, and the mounting groove 103 on the right can be fastened to the right, making the connection method relatively simple. Moreover, it can also make the force on the mounting grooves 103 on both sides of the middle base plate 101 more even, improving the connection reliability between the metal roof panel 10 and the intermediate support 11.

[0049] Optionally, the base plate portion 101 and the first overlap portion 102 can be along a first direction of the metal roof panel 10 ( Figure 1 As shown by the middle arrow, the first fastening part 104 protrudes from one side of the mounting groove 103 to achieve the fastening between the first fastening part 104 and the second fastening part 111. The fastening method is simple and easy to implement.

[0050] Specifically, the second fastening part 111 of the intermediate support 11 protrudes from one side of the intermediate support 11, and the protrusion direction of the second fastening part 111 is opposite to the protrusion direction of its corresponding first fastening part 104, so as to achieve direct fastening between the two.

[0051] It should be noted that, in practical applications, the protruding directions of the first fastening part 104 and the second fastening part 111 can also be set at a preset angle with the first direction. For example, the preset angle can be 30 degrees, 50 degrees, or 65 degrees, etc. The embodiments of this application do not specifically limit the protruding directions of the first fastening part 104 and the second fastening part 111.

[0052] Optionally, the number of mounting slots 103 is even; along the first direction, the mounting slots 103 are combined in pairs to form mounting slot groups, and in the two mounting slots 103 that make up the mounting slot group, the protruding directions of the first fastening parts 104 are either far apart or close together. In this way, during the process of installing the metal roof panel 10 to the intermediate support 11, the intermediate supports 11 in the two mounting slots 103 in the same group of mounting slots can be fastened in directions that are far apart or close together, so as to improve the fastening stability of the two mounting slots 103 in the same group of mounting slots and the intermediate support 11 and avoid damage to the metal roof panel 10. As a result, the risk of water leakage of the metal roof panel 10 can be reduced and the wind resistance of the metal roof panel 10 can be improved.

[0053] Furthermore, during the installation of the metal roof panel 10 to the intermediate support 11, if the intermediate supports 11 in the two mounting slots 103 of the same set of mounting slots are fastened in opposite directions, the intermediate supports 11 can be prevented from detaching from the mounting slots 103 of the metal roof panel 10, thus improving the connection reliability between the metal roof panel 10 and the intermediate support 11 and improving the wind uplift resistance of the metal roof panel 10.

[0054] like Figure 6As shown, the dimension of the mounting groove 103 in the first direction is larger than the dimension of the intermediate support 11 in the first direction; a gap is formed between the intermediate support 11 and the mounting groove 103 along the first direction. Due to the existence of the gap, the intermediate support 11 and / or the metal roof panel 10 can be adjusted in position along the first direction, and the first fastening part 104 of the metal roof panel 10 can be better fastened to the second fastening part 111 of the intermediate support 11, thereby improving the connection strength between the intermediate support 11 and the metal roof panel 10.

[0055] like Figure 2 As shown, the mounting groove 103 further includes: a first extension 1031, a second extension 1032, and a third extension 1033; wherein, the first extension 1031 extends from one of the two adjacent base plate portions 101 to the first overlapping portion 104; the second extension 1032 extends from the other of the two adjacent base plate portions 101 to the first fastening portion 104; the third extension 1033 extends from the first overlapping portion 104 to the first fastening portion 104; the first extension 1031, the first overlapping portion 102, the third extension 1033, the first fastening portion 104, and the second extension 1032 together form the mounting groove 103.

[0056] Specifically, the first extension 1031, the first overlapping portion 102, the third extension 1033, the first fastening portion 104, and the second extension 1032 can be formed by stamping. The first fastening portion 104 can be formed between the second extension 1032 and the third extension 1033, making the forming method relatively simple. Moreover, since the first fastening portion 104 only needs to be formed on one side of the mounting groove 103, the processing technology of the mounting groove 103 can be further simplified.

[0057] Optionally, the first fastening portion 104 is parallel to the base plate portion 101. In this way, during the formation of the first fastening portion 104, the base plate portion 101 can be referenced during processing to improve the processing accuracy of the first fastening portion 104. Furthermore, since the first fastening portion 104 is parallel to the base plate portion 101, during the installation of the metal roof panel 10 onto the intermediate support 11, the movement or adjustment of the metal roof panel 10 along the base plate portion 101 (first overlapping portion 102) can achieve the fastening between the first fastening portion 104 and the second fastening portion 111 on the intermediate support 11, resulting in a simple and easy-to-implement fastening method.

[0058] It should be noted that the first fastening part 104 and the base plate part 101 can also be set at a preset angle, and this embodiment does not limit this.

[0059] Optionally, the first extension 1031 is inclined relative to the second extension 1032 and the third extension 1033, so that the width of the top of the mounting groove 103 is smaller than the width of the bottom, forming a mounting groove 103 with a trapezoidal cross-sectional shape. In this way, when the mounting groove 103 is inserted into the intermediate support 11 from top to bottom, it is easier to insert the mounting groove 103 into the intermediate support 11, thereby improving the installation efficiency of the metal roof panel 10 and the intermediate support 11.

[0060] Optionally, the included angles between the second extension 1032 and the first fastening part 104, and between the third extension 1033 and the first fastening part 104, are all acute angles. In specific applications, by setting the included angle between the second extension 1032 and the first fastening part 104 to an acute angle, and the included angle between the third extension 1033 and the first fastening part 104, it is not only convenient to insert the mounting groove 103 of the metal roof panel 10 into the intermediate support 11, but also to make it difficult for the first fastening part 104 to come off the second fastening part 111 on the intermediate support 11, thereby improving the connection reliability between the metal roof panel 10 and the intermediate support 11.

[0061] In summary, the metal roofing panels described in the embodiments of this application may include at least the following advantages:

[0062] In this embodiment, the first overlapping portion of the metal roof panel and two adjacent bottom plate portions can be enclosed to form an installation groove for installing an intermediate support. Since a first fastening portion is provided on one side of the installation groove, this first fastening portion can be used to fasten with the intermediate support. During the installation of the installation groove to the intermediate support, only the first fastening portion on one side of the installation groove needs to be fastened to the intermediate support, avoiding the need to forcibly press the installation groove onto both sides of the intermediate support. This not only reduces the installation difficulty between the intermediate support and the metal roof panel but also avoids damage or deformation to the installation groove of the metal roof panel and the intermediate support, thereby reducing the risk of water seepage in the metal roof panel and improving its wind resistance.
