Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic module installation. Specifically, it relates to a profiled metal sheet, a module, and a profiled metal roof panel. Background Art

[0002] Photovoltaic modules can convert solar energy into electrical energy, which is one of the important ways to utilize solar energy. In order to install photovoltaic modules on a building roof, usually a profiled metal sheet capable of carrying the photovoltaic modules is fixed on the roof, and the photovoltaic modules are fixed on the profiled metal sheet.

[0003] Although there are various forms of profiled metal sheets currently, most of them cannot achieve the stable installation of photovoltaic modules and have poor wind uplift resistance. For example, a commonly used profiled metal sheet has a relatively wide and long plate shape. Looking along the width direction, convex bearing surfaces are provided on both sides, and a convex bearing portion is provided in the middle. When in use, multiple profiled metal sheets are arranged side by side, and the adjacent sides are bent and fixed together. A boat-shaped support fixed to the roof is provided below the adjacent bearing surfaces of the adjacent profiled metal sheets, and an intermediate support fixed to the middle of the roof is provided inside the bearing portion. The profiled metal sheet is supported and fixed through the boat-shaped support and the intermediate support. The photovoltaic module is placed on the bearing surface and the bearing portion of the profiled metal sheet from above, and both sides of the photovoltaic module are limited by the two sides of the corresponding profiled metal sheet.

[0004] Since the intermediate support corresponding to the bearing portion in the middle is a single-sided suspended structure, it is easily pressed and deformed, thus disengaging from the bearing portion, causing the profiled metal sheet to lose its wind uplift resistance; moreover, the profiled metal sheet does not fix the photovoltaic module, and under the action of negative wind pressure, the photovoltaic module is easily disengaged from the profiled metal sheet, resulting in poor wind uplift resistance. Summary of the Invention

[0005] The purpose of the embodiments of the present application is to provide a profiled metal sheet, a module, and a profiled metal roof panel, which can improve the wind uplift resistance of the profiled metal sheet; and can achieve the stable installation of the photovoltaic module and ensure the wind uplift resistance of the photovoltaic module.

[0006] In a first aspect, the embodiments of the present application provide a profiled metal sheet, which includes a long strip-shaped plate body. Edge convex ribs extending along the length direction are respectively bent on both sides of the plate body. The upper surface of the edge convex rib is an edge support surface. The plate body below each edge support surface is bent to form a snap groove, and the opening of the snap groove faces away from the other edge convex rib. At least one middle convex rib extending along the length direction is bent on the plate body between the two edge convex ribs. The upper surface of the middle convex rib is a middle support surface. A cavity with an opening facing downwards is provided inside the middle convex rib. The cavity includes a clamping member space and a guiding space arranged adjacent to each other up and down. The width at the boundary between the clamping member space and the guiding space is smaller than the width of the adjacent upper and lower regions.

[0007] In the above implementation process, the middle support surface and the edge support surface of the corrugated metal plate are used to support the photovoltaic module. The snap groove below the edge support surface can be used to set the snap parts to lock the edge of the photovoltaic module with the corrugated metal plate; the internal cavity of the middle ridge is used to facilitate the arrangement of the support part to support the middle ridge; and the boundary between the clamping space and the guide space adopts a tight mouth design, so that the support part can be easily clamped by the clamping space, which can prevent the corrugated metal plate from separating from the support part, thereby improving the wind-resistant performance of the corrugated metal plate; and the design of the above-mentioned edge ridges and middle ridges can achieve stable installation of the photovoltaic module and ensure the wind-resistant performance of the photovoltaic module.

[0008] In one possible implementation, the central ridge includes a central supporting surface, an inclined surface formed by extending outward from both sides of the central supporting surface, a clamping surface formed by extending inward from the inclined surface on each side, and a guide surface formed by extending outward from the clamping surface on each side. The central supporting surface, the inclined surface and the clamping surface together form a clamping space that is narrow at the top and wide at the bottom; a guide space that is narrow at the top and wide at the bottom is formed between the two guide surfaces of the central ridge.

[0009] In the above implementation process, the card space of the middle ridge is narrow at the top and wide at the bottom, and the guide space is narrow at the top and wide at the bottom, which makes it easy to insert a specific support into the middle ridge, especially into the card space. Moreover, due to the limitation of the card space, the support is not easy to fall out of the middle ridge.

[0010] In one possible implementation, the central ridge includes a central supporting surface, an inclined surface formed by extending inward from both sides of the central supporting surface, and a guide surface formed by extending outward from the inclined surface on each side. The central supporting surface and the inclined surface together form a card space that is wide at the top and narrow at the bottom; a guide space that is narrow at the top and wide at the bottom is formed between the two guide surfaces of the central ridge.

[0011] In the above implementation process, the card space of the middle ridge is wide at the top and narrow at the bottom, and the guide space is narrow at the top and wide at the bottom. As long as a specific support member can be inserted into the middle ridge, especially into the card space, the narrowest position inside the middle ridge can prevent the part of the support member inserted into the card space from falling out.

[0012] In a possible implementation, the edge ridge above the snap groove is a hollow structure, and the upper surface of the plate forming the snap groove is inclined toward the opening direction of the snap groove;

[0013] Alternatively, the edge ridge above the snap groove is a solid structure, and the upper surface of the plate body forming the snap groove overlaps below the corresponding edge support surface.

[0014] In the above implementation process, since the edge convex rib is a hollow structure and the surface of the plate body adjacent to the buckle groove is inclined at a specific angle, when a buckle member for locking the photovoltaic module is arranged in the buckle groove, under the action of the buckle member on the edge convex rib, the inclined surface of the edge convex rib will be flattened, thereby ensuring the straight state of the edge convex rib, especially the straight state of the edge support surface.

[0015] Since the surface of the plate body adjacent to the buckle groove overlaps below the corresponding edge support surface, the effect of strengthening the edge support surface can be achieved, reducing or even avoiding the deformation of the edge support surface due to force.

[0016] In a possible implementation manner, the plate bodies on the outer side of the edge convex rib are respectively bent to form connecting portions. Each connecting portion includes a vertical surface formed by the upward extension of the plate body on the outer side of the corresponding edge convex rib and a horizontal surface extending from the vertical surface to one side, and the outer shapes of the two connecting portions are matched.

[0017] In the above implementation process, the same profiled metal plates are arranged side by side, and the adjacent sides of the adjacent plate bodies have connecting portions with matching outer shapes, and the connecting portions are all composed of vertical surfaces and horizontal surfaces, so that they can overlap with each other, thereby realizing the connection setting of multiple profiled metal plates to meet the requirements of roof laying.

[0018] In a possible implementation manner, the plate body between the edge convex rib and the middle convex rib is further provided with protruding reinforcing ribs, which are arranged at intervals, and the reinforcing ribs are not higher than the heights of the edge convex rib and the middle convex rib.

[0019] In the above implementation process, the reinforcing ribs are formed by the bending and undulating design of the plate body to strengthen the strength of the plate body.

[0020] In a second aspect, the embodiments of the present application provide a profiled metal plate assembly, which includes a plurality of profiled metal plates provided in the first aspect, all the plate bodies are arranged side by side, and the adjacent side edges of the adjacent plate bodies are connected side by side.

[0021] In the above implementation process, a plurality of profiled metal plates are connected side by side to form a profiled metal plate assembly, and then the photovoltaic module is laid and installed, which can meet the requirements of roof laying.

[0022] In a third aspect, the embodiments of the present application provide a profiled metal roof panel, which includes a profiled metal plate. The middle part of the profiled metal plate is bent to form at least one middle convex rib. The upper surface of the middle convex rib is a middle support surface. The inside of the middle convex rib has a cavity with an opening facing downwards. The cavity includes an upper and lower adjacent card member space and a guiding space. The width at the boundary between the card member space and the guiding space is smaller than the width at other positions of the middle convex rib; a middle support is arranged inside the middle convex rib. The middle support includes a buckle portion and a support portion. The buckle portion is clamped in the card member space, the support portion passes through the guiding space, and one end is connected to the buckle portion and the other end extends out of the opening for fixing to the roof.

[0023] In the above implementation process, the middle support surface of the middle convex rib can carry the photovoltaic module, and both the middle convex rib and the middle support seat inside it are designed according to a specific structure, which can ensure the support effect of the middle convex rib on the photovoltaic module. The buckle part is clamped in the card space, and the wind uplift resistance performance of the photovoltaic module can also be ensured.

[0024] In a possible implementation manner, the middle support seat is formed by bending a single sheet of material or composed of two sheets of material arranged in a bent manner. The support part of the middle support seat is a hollow structure and its outer shape matches the card space. The support part can be a hollow structure or a solid structure.

[0025] In the above implementation process, the middle support seat is easy to process, and the support part is a hollow structure with a certain elasticity. It can deform and insert into the card space through the guiding space, and can also deform under the action of the card space and can restore its original shape.

[0026] In a fourth aspect, an embodiment of the present application provides a profiled metal roof panel, which includes the profiled metal plate assembly provided in the second aspect. A middle support seat is arranged inside the middle convex rib. The middle support seat includes a hollow buckle part and a support part. The buckle part is clamped in the card space, the support part passes through the guiding space, and one end is connected to the buckle part, and the other end is used to be fixed to the roof surface; and an edge support seat for fixing to the roof surface is arranged below the edge support surface at the connection of adjacent plate bodies.

[0027] In the above implementation process, the stable installation of the photovoltaic module can be realized through the profiled metal plate assembly, and through the profiled metal plate assembly, the edge support seat and the middle support seat, the whole can be installed on the roof surface and the wind uplift resistance performance can be ensured.

[0054] First Embodiment

[0055] Please refer to Figure 1 and Figure 2 , a profiled metal sheet 100 provided in this embodiment includes a strip-shaped plate body 110. From the cross-section in the width direction of the plate body 110, both sides of the plate body 110 are bent to form edge ridges 120 extending along the length direction. The upper surface of the edge ridge 120 is an edge support surface 1, and the plate body 110 below each edge support surface 121 is bent to form a snap groove 122. The opening of the snap groove 122 faces away from the direction of the other edge ridge 120. The plate body 110 between the two edge ridges 120 is bent to form a middle ridge 130 extending along the length direction. The upper surface of the middle ridge 130 is a middle support surface 131. The middle support surface 131 and the edge support surface 121 are usually in the same plane. The middle ridge 130 has a cavity with an opening facing downwards inside. The cavity includes a card member space 136 and a guiding space 137 arranged adjacent to each other up and down. The width at the boundary between the card member space 136 and the guiding space 137 is smaller than the width of the adjacent areas above and below.

[0056] It should be noted that in the embodiments of the present application, unless otherwise specified, all shape descriptions are viewed from the cross-section in the width direction of the plate body 110. For example, the width at the boundary between the card member space 136 and the guiding space 137 is smaller than the width of the upper and lower adjacent regions, which means that when viewed from the cross-section in the width direction of the plate body 110, the boundary between the card member space 136 and the guiding space 137 is relatively the narrowest, thus forming a constriction to prevent the components in the card member space 136 from coming out.

[0057] In order for the middle convex rib 130 to provide a middle support surface and form the card member space 136 and the guiding space 137, in this embodiment, the plate body 110 forming the middle convex rib 130 includes a middle support surface 131, inclined surfaces 132 respectively extending outward from both sides of the middle support surface 131, card member surfaces 133 extending inward from each side of the inclined surface 132, and guiding surfaces extending outward from each side of the card member surface 133. The middle support surface 131, the inclined surfaces 132 and the card member surfaces 133 together form a card member space 136 that is narrower at the top and wider at the bottom. The card member surfaces 133 are inclined towards the corresponding middle support surface 131, thus forming a hooked corner with the inclined surfaces 132; a guiding space 137 that is narrower at the top and wider at the bottom is formed between the two guiding surfaces of the middle convex rib 130; the guiding surface includes two sections, one end is a guiding horizontal surface 134 connected to and extending outward from the card member surface 133, and a guiding inclined surface 135 connected to and extending outward from the guiding horizontal surface 134. Such a design of the guiding surface forms a larger guiding space 137, which is convenient for later setting of the support member and the fixing member for fixing the support member.

[0058] It should be noted that the form of the middle convex rib 130 can be various, as long as there is a constriction design between the card member space 136 and the guiding space 137. The number of the middle convex ribs 130 can also be set at two or more at intervals according to actual needs.

[0059] In order for the edge convex rib 120 to provide an edge support surface and form the snap groove 122, the plate body 110 forming the edge convex rib 120 includes an edge support surface 121 and a bent portion formed by bending the edge support surface 121 downward, and the bent portion needs to be able to form the snap groove 122. In this embodiment, the edge convex rib 120 above the snap groove 122 of the middle support surface 131 is a hollow structure, and the upper surface of the plate body 110 forming the snap groove 122 is inclined towards the opening direction of the snap groove 122. In other embodiments, the edge convex rib 120 above the snap groove 122 can also be a solid structure, and the upper surface of the plate body 110 forming the snap groove 122 overlaps below the corresponding edge support surface 121.

[0060] To achieve the connection between profiled metal sheets 100, the sheet bodies 110 outside the side convex ribs 120 are respectively bent to form connection parts 140. Each connection part 140 includes a vertical surface 141 in a vertical state formed by the upward extension of the sheet body 110 outside the corresponding side convex rib 120, and a horizontal surface 142 in a horizontal state extending from the vertical surface 141 to one side. The outer shapes of the two connection parts 140 match, that is, when the two profiled metal sheets 100 are arranged in parallel, the connection part 140 of one sheet body 110 can overlap with the adjacent connection part 140 of the adjacent sheet body 110, and then the overlapping part is processed to be deformed, so that the two sheet bodies 110 are connected together. In this embodiment, the horizontal surface 142 of one connection part 140 also extends downward to form a short vertical surface 143, and the horizontal surface 142 of the other connection part 140 does not form a short vertical surface 143, but the end of the horizontal surface 142 is folded back and overlaps under the horizontal surface 142.

[0061] In this embodiment, the sheet bodies 110 between the side convex ribs 120 and the middle convex ribs 130 are also provided with protruding reinforcing ribs 150 at intervals. The reinforcing ribs 150 are all directly bent from the sheet bodies 110, and the reinforcing ribs 150 are not higher than the heights of the side convex ribs 120 and the middle convex ribs 130. In this embodiment, the shape of the reinforcing ribs 150 is trapezoidal. In other embodiments, the reinforcing ribs 150 can also be triangular, oval or circular.

A profiled metal sheet 200 provided in this embodiment has a structure substantially the same as that of the first embodiment, except that: in this embodiment, the vertical surface 241 of each connection part 140 is also bent, but the overall is in a vertical state. This setting can ensure that after the matching connection parts 140 overlap, the bent parts of the vertical surface 241 can overlap and be clamped together, and they can be connected together without special processing.

[0064] Third Embodiment

[0065] Please refer to Figure 1 and Figure 4 . A profiled metal sheet 300 provided in this embodiment has a structure substantially the same as that of the first embodiment, except that: in this embodiment, the card member surface 133 inclines away from the corresponding middle support surface 131, so as to form an open corner with the inclined surface 132, and the card member space 136 is narrow at the top, wide in the middle and narrow at the bottom; an auxiliary convex rib 310 is also provided between each connection part 140 and the corresponding side convex rib 120. The structure of the auxiliary convex rib 310 is symmetrically designed with the side convex rib 120 and has an auxiliary snap groove with the snap direction facing inwards. The corresponding snap groove 122 and the auxiliary snap groove act together to facilitate the setting of the card member.

The guiding surface 433 is designed as an inclined surface. The middle support surface 131 and the inclined surfaces 432 together form a clamping member space 434 that is wider at the top and narrower at the bottom; a guiding space 435 that is narrower at the top and wider at the bottom is formed between the two guiding surfaces 433 of the middle convex rib 430.

[0068] Fifth Embodiment

[0069] Please refer to Figure 5 、 Figure 6 and Figure 7 ,A profiled metal sheet 500 provided in this embodiment has a structure substantially the same as that of the fourth embodiment, except that: in this embodiment, the guiding surface in the middle convex rib 530 includes two sections, one is a guiding horizontal surface 533 connected to and extending outwards from the inclined surface 432, and a guiding inclined surface 534 connected to and extending outwards from the guiding horizontal surface 533.

[0070] Sixth Embodiment

[0071] Please refer to Figure 2 、 Figure 8, a profiled metal roof panel 600 provided in this embodiment includes a profiled metal plate 100. At least one central convex rib 130 is formed by bending the middle part of the profiled metal plate 100. The structure of the central convex rib 130 is the same as that of the central convex rib 130 in the first embodiment. The upper surface of the central convex rib 130 is a central support surface 131. The inside of the central convex rib 130 is a hollow structure and is divided into a clamping member space 136 and a guiding space 137 arranged up and down. The width at the boundary between the clamping member space 136 and the guiding space 137 is smaller than the width at other positions of the central convex rib 130. Specifically, the plate body 110 forming the central convex rib 130 includes a central support surface 131, inclined surfaces 132 extending outward from both sides of the central support surface 131 respectively, clamping member surfaces 133 extending inward from each inclined surface 132, and guiding surfaces extending outward from each clamping member surface 133. The central support surface 131, the inclined surfaces 132 and the clamping member surfaces 133 together form a clamping member space 136 that is narrower at the top and wider at the bottom. The clamping member surfaces 133 are inclined towards the corresponding central support surface 131, thus forming a hook-shaped corner with the inclined surfaces 132; a guiding space 137 that is narrower at the top and wider at the bottom is formed between the two guiding surfaces of the central convex rib 130; the guiding surface includes two sections, one end is a guiding horizontal surface 134 connected to the clamping member surface 133 and extending outward, and a guiding inclined surface 135 connected to the guiding horizontal surface 134 and extending outward.

[0072] A matching central support 610 is arranged inside the central convex rib 130. The central support 610 includes a clamping part 611 and a support part 612. The clamping part 611 is clamped in the clamping member space 136, the support part 612 passes through the guiding space 137, and one end is connected to the clamping part 611, and the other end is used to be fixed on the roof. The central support 610 is usually formed by bending the same sheet of material. The clamping part 611 of the central support 610 is a hollow structure and its outer shape matches the clamping member space 136, and the support part 612 is a solid structure.

[0073] Specifically, the central support 610 is in a T shape, and the widest position of the clamping part 611 as the T-shaped head is stuck in the widest position of the clamping member space 136, that is, the corner formed by the inclined surface 132 and the clamping member surface 133; the support part 612 as the T-shaped tail is composed of the sheets extending downward from both sides of the sheet of the clamping part 611 and fitting together; and the sheets of the support part 612 also extend outward respectively to form fixing parts 613. By setting fixing members 614 such as screws on the fixing parts 613, the central support 610 can be fixed on the roof.

[0074] Please refer to Figure 9 and Figure 10, in this embodiment, both the middle convex rib 130 and the middle support 610 are barbed and are engaged with each other. Under the action of negative wind pressure, when the hollow snap part 611 of the middle support 610 is subjected to an upward pulling force, it is more firmly engaged with the clamping space 136 of the middle convex rib 130 by expanding and contracting outwards; the support part 612 of the middle support 610 plays a supporting role, and eliminates the positioning error of its own installation by slightly swaying left and right, improving the convenience and efficiency of construction and installation.

Inside the middle rib 130 of each profiled metal plate 100, there is a middle support 910. The designs of the middle rib 130 and the middle support 910 are the same as those in the sixth embodiment and will not be elaborated here. Below the edge support surface 121 at the connection of the adjacent plate bodies 110, there is an edge support 920 for fixing to the roof, such as a boat-shaped support. Through the edge support 920 and the middle support 910, the profiled metal plate 100 can be installed on the purlins of the roof. In other embodiments, the middle rib 130 and the middle support 910 can be adjusted otherwise, and the edge rib 120 can also be adjusted otherwise.

[0081] Tenth Embodiment

[0082] Please refer to Figure 1 and Figure 14 , a profiled metal plate provided in this embodiment has a structure substantially the same as that of the first embodiment, except that: in this embodiment, the edge rib 930 above the snap groove 122 is a solid structure, and the upper surface of the plate body 110 forming the snap groove 122 overlaps below the corresponding edge support surface. In other embodiments, an auxiliary rib is further provided between each connecting part 140 and the corresponding edge rib 930. The structure of the auxiliary rib is symmetrically designed with the edge rib 930, both are solid structures, and have an auxiliary snap groove with the snap direction facing inwards. The auxiliary snap groove is symmetrically arranged with the opposite snap groove 122. It should be noted that the "solid structure" in the embodiments of this application is relative to the "hollow structure", and its interior is not completely without space, but refers to the structure formed when the plate bodies 110 are as close to each other as possible and even in contact with each other.

[0083] Eleventh Embodiment

[0084] Please refer to Figure 1 and Figure 15 , a profiled metal plate provided in this embodiment has a structure substantially the same as that of the first embodiment, except that: in this embodiment, the shape of the reinforcing rib 940 is approximately triangular, with a relatively small width and a relatively large number.

[0085] Twelfth Embodiment

[0086] Please refer to Figure 16, a profiled metal roof panel provided in this embodiment has a structure substantially the same as that of the sixth embodiment, except that: the middle support 951 is formed by bending a sheet into a specific shape and symmetrically arranging it. Specifically, the buckle part 952 of the middle support 951 is divided into left and right parts, and there is a certain distance between the two parts. The support parts 953 connecting the sheets of the left and right buckle parts 952 are also separated left and right, that is, a hollow structure. The sheets of the support parts 953 of the left and right parts also extend outwards respectively to form fixing parts 613, and finally the two sheets are connected together. Although the buckle part 952 of the middle support 951 is a split type, it is still a hollow structure and its outer shape matches the clamping space of the middle convex rib 130, jointly supporting the middle convex rib 130.

[0087] The thirteenth embodiment

[0088] Please refer to Figure 17 , a profiled metal roof panel provided in this embodiment has a structure substantially the same as that of the twelfth embodiment. The middle support 961 is formed by bending a sheet into a specific shape and symmetrically arranging it. The buckle part 962 of the middle support 961 is divided into left and right parts. The support parts 963 connecting the sheets of the left and right buckle parts 962 are also separated left and right. The sheets of the support parts 963 of the left and right parts also extend outwards respectively to form fixing parts 613, and finally the two sheets are connected together. The difference is that: the outer shape of the buckle part 962 of the middle support 961 does not match the clamping space of the middle convex rib 130, that is, the vertex of the buckle part 962 is separated from the middle convex rib 130 by a certain distance, and both sides of the buckle part 962 can be clamped at the corresponding positions in the clamping space of the middle convex rib 130, so as to achieve the effect of supporting the middle convex rib 130.

[0089] It should be noted that for different forms of the middle convex rib 130, the split middle support 951 formed by the above two sheets can be used, as long as the outer shape of the buckle part 952 of the middle support 951 matches the clamping space of the middle convex rib and can play a role in supporting and preventing the profiled metal plate from coming off.

[0090] In summary, the profiled metal plate, component and profiled metal roof panel of the embodiments of the present application improve the wind uplift resistance performance of the profiled metal plate; and can realize the stable installation of the photovoltaic module and ensure the wind uplift resistance performance of the photovoltaic module.

[0091] The above are only the embodiments of the present application and are not used to limit the protection scope of the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
