[0002] With the continuous development of the construction industry, roof panels have been widely used in various types of buildings. During the construction of traditional metal roof panels, connection pieces are added at the edge-locking positions of the roof panels to connect the edge-locking and the sliding brackets, so as to achieve the effects of waterproofing and wind resistance.

[0003] However, due to the setting of the connection pieces, there is always a thickness difference between the connection pieces and the edge-locking of the roof panel. Once the rainwater overflows the edge-locking seam, the rainwater will flow into the room through the gap of the thickness difference, resulting in water leakage, and the wind resistance effect is not good.

Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without creative efforts shall fall within the protection scope of the embodiments of the present invention.

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments, and are not intended to limit the present invention.

[0042] Figure 1 Schematic side view structure of a roof panel in the embodiments of the present invention, Figure 2 Schematic three-dimensional structure of a roof panel in the embodiments of the present invention, as Figure 1 and Figure 2 shown.

[0043] The embodiments of the present invention provide a side-supported roof panel, including: a main body section 10 and a side section 20.

[0044] Among them, the main body section 10 has opposite first and second surfaces. Side sections 20 that are bent towards the first surface are respectively provided on opposite sides of the main body section 10. A limiting structure 21 and a locking edge structure 22 are respectively provided on each side section 20. A bearing section 23 is provided between the limiting structure 21 and the locking edge structure 22, and each bearing section 23 extends in the same direction.

[0045] Combined with Figure 1 and Figure 2 , see Figure 3 and Figure 4, the limiting structure 21 on one side of the roof panel can enclose a limiting space with the limiting structure 21 on the other side of the adjacent roof panel. The edge-locking structure 22 on one side of the roof panel can be locked with the edge-locking structure 22 on the other side of the adjacent roof panel. The bearing section 23 on one side of the roof panel can form a bearing platform with the bearing section 23 on the other side of the adjacent roof panel.

[0046] The technical solution provided by the embodiment of the present invention, by arranging the limiting structure 21 on the side section 20 of the roof panel, and the limiting structure 21 cooperating with the corresponding connecting bracket 30, enables the roofing system to have good wind resistance. At the same time, it cooperates with the edge-locking structure 22 on the side section 20 to achieve a continuous seamless lock seam, ensuring that the lock seam can achieve a good waterproof effect, thereby improving the waterproof and wind resistance of the roofing system. In addition, referring to Figure 5 , a bearing section 23 is arranged on the side section 20, changing the edge-locking method and the edge style of the panel, so that a bearing platform for integrating the photovoltaic module 50 can be provided after the edge-locking of the roof panel, enabling the roof panel to be used in matching with the photovoltaic module 50 and meeting the requirements of photovoltaic integration.

[0047] In the embodiment of the present invention, the main body section 10 can be a plane or a non-plane, and can be made into corresponding shapes according to different requirements. For example, when a plane is adopted, in order to improve the stiffness and strength, a reinforcing structure with protrusions or depressions can be arranged on the plane, or a platform for support (which can also be called a wave crest structure) and other structures can be arranged. The roof panel includes but is not limited to being made of metal sheets through processes such as stamping and rolling. The metal sheets include sheets with an anti-corrosion layer on the surface to improve the corrosion resistance of the sheets. The sheets include but are not limited to steel sheets, and the anti-corrosion layer includes but is not limited to paint layers, galvanized layers, etc.

[0048] The side section 20 and the main body section 10 can be an integrally formed structure, made by bending or stamping processes. One forming method is to select a section with a predetermined length at both ends of the main body section 10, and then through the bending process, bend along the direction from the second surface to the first surface, so as to Figure 1Taking the middle orientation as an example, it is bent upward relative to the main body section 10, thereby forming the side sections 20 on both sides. Then, taking the side section 20 on the right side as an example, starting from the main body section 10, a predetermined first section a is further selected upward on the side section 20, and then the side section 20 is bent to the left with the vertex of section a far from the main body section 10 as the bending point. Starting from the vertex of section a far from the main body section 10, a predetermined second section b is selected, and the side section 20 is bent upward with the vertex of section b far from section a as the bending point. Starting from the vertex of section b far from section a, a predetermined third section c is selected, and the side section 20 is bent to the right with the vertex of section c far from section b as the bending point, thus completing the limiting structure 21. Starting from the vertex of section c far from section b, a predetermined fourth section d is selected, and section d is used as the bearing section 23. Thus, the limiting structure 21 is formed by sections a, b, and c, section d is the bearing section 23, and a hemming structure 22 is provided at one end of the bearing section 23 far from the limiting structure 21. The extending direction of the hemming structure 22 is not specifically limited. According to different requirements, it can extend to the left side uniformly or to the right side uniformly.

[0049] See Figure 3 and Figure 4 , when the roofing panel is assembled on the roof purlin 40 to form a roofing system, the roofing panel can also be used in cooperation with a plurality of connecting brackets 30. Combining Figure 4 See Figure 5 and Figure 6 , in an embodiment of the present invention, one implementation manner of the connecting bracket 30 is that the connecting bracket 30 includes a base 31 and a connecting head 32. The base 31 has a bearing surface 33 for bearing the main body section 10 of the roofing panel, and the connecting head 32 can be arranged in the limiting space. The function of the base 31 is to connect with the roof purlin 40 and provide support for the connecting head 32. The specific implementation manner of the base 31 is not specifically limited here as long as the above functions can be achieved. The function of the connecting head 32 is to be arranged in the limiting space and cooperate with the base 31 to restrict the position of the roofing panel to ensure the stability of the position and state of the roofing panel. Of course, the specific implementation manner of the connecting head 32 is not specifically limited here as long as the above functions can be achieved.

[0050] Furthermore, the implementation manners of the base 31 and the connecting head 32 include but are not limited to the following manners. Continuing to refer to Figure 5 and Figure 6 , the base 31 includes a top plate 311, two side plates 312, and two connecting plates 313. The top plate 311 and the two side plates 312 form an inverted U-shaped main body. The closed end of the inverted U-shaped main body is the bearing surface 33, and the connecting plates 313 are respectively arranged at one ends of the two side plates 312 far from the top plate 311. The connecting head 32 includes at least one support plate 321 and two limiting plates 322. One end of the support plate 321 is connected to the top plate 311, and the two limiting plates 322 are arranged at one end of the support plate 321 far from the top plate 311 and extend away from each other to adapt to the shape of the limiting space.

[0051] Further, to enhance the strength of the base 31, a plurality of reinforcing plates 35 are provided inside the inverted U-shaped main body. By providing the plurality of reinforcing plates 35, the stress on the inverted U-shaped main body can be assisted in absorption, the strength of the base 31 can be enhanced, and the deformation of the base 31 can be reduced. There are various connection methods between the plurality of reinforcing plates 35 and the base 31. For example, among the plurality of reinforcing plates 35, there are transverse reinforcing plates, and both ends of the transverse reinforcing plate are respectively connected to the side plates 312. The transverse reinforcing plate is used to absorb the transverse stress and prevent the two side plates 312 from deforming. Among the plurality of reinforcing plates 35, there are also vertical reinforcing plates. One end of the vertical reinforcing plate is connected to the top plate 311, and the other end is connected to the transverse reinforcing plate. The position of the vertical reinforcing plate corresponds to the position of the support plate 321. The vertical reinforcing plate is used to absorb the vertical stress and prevent the top plate 311 from deforming.

[0052] Further, to enhance the load-bearing strength of the load-bearing platform, the connector 32 further includes a load-bearing frame 34. The load-bearing frame 34 is arranged on the limiting plate 322 and has a support plane that abuts against the load-bearing section 23. The support plane provides support for the load-bearing platform to share the force on the load-bearing platform, so that the force from the photovoltaic module 50 received by the load-bearing platform can be conducted to the connection bracket 30 and the roof purlin 40, so that the load-bearing platform, the connection bracket 30 and the roof purlin 40 jointly bear the force of the photovoltaic module 50 and prevent the load-bearing platform from deforming.

[0053] In an embodiment of the present invention, a construction method of the roof panel is as follows: For the convenience of description, taking Figure 1 the orientation in Figure 1 as an example, it is now defined that Figure 1 the left-right direction in

[0054] is the length direction of the roof panel, and

[0055] the direction perpendicular to the paper surface in

[0055] is the width direction of the roof panel.

[0055] In the construction, first, a plurality of connection brackets 30 are arranged at intervals along the length direction of the roof panel and fixed to the roof purlin 40. The fixing methods include but are not limited to fixing by self-tapping screws. The plurality of connection brackets 30 arranged at intervals can be set corresponding to different limiting spaces. Further, for one limiting space, the corresponding connection bracket 30 can be one. One connection bracket 30 extends along the width direction of the roof panel and penetrates the entire limiting space. The connection bracket 30 can also be multiple. The multiple connection brackets 30 are arranged at intervals along the width direction of the roof panel and are connected corresponding to the same limiting space. In an embodiment of the present invention, taking one limiting space corresponding to one connection bracket 30 as an example for description, this does not constitute an improper limitation of the embodiment of the present invention.Secondly, a roof panel is assembled between two connecting brackets 30 spaced apart along the length direction. Since the roof panel can be made of metal sheet and the side section 20 has a certain elasticity relative to the main section 10, the roof panel can be snapped into place between the two connecting brackets 30 by extrusion. Alternatively, along the width direction of the roof panel, in accordance with the shapes of the connecting brackets 30 and the limiting structure 21, the roof panel can be inserted between adjacent connecting brackets 30.

[0056] After assembly, the opposing limiting structures 21 on adjacent roof panels can enclose to form a limiting space, and the opposing edge-locking structures 22 can be locked with each other. For the assembled roof panel, its main section 10 is carried on the bearing surface 33 of the connecting bracket 30, and the connecting head 32 on the connecting bracket 30 is located within the limiting space. The limiting space provides a bending load-bearing structure for the roof panel against wind, and the bending load-bearing structure is connected to the connecting bracket 30. When the "wind-lifting" situation occurs to the roof panel in a windy environment, the bending load-bearing structure and the connecting bracket 30 work together to resist the "wind-lifting", ensuring that the roof panel remains stable, thereby significantly improving the wind resistance of the roof panel and the roofing system formed thereby.

[0057] See Figure 7 , after adjacent roof panels are assembled, the edge-locking structure 22 on one side of the roof panel can be locked with the edge-locking structure 22 on the other side of the adjacent roof panel. The locking method includes but is not limited to one edge-locking structure 22 wrapping the other edge-locking structure 22 and bending inward by 360 degrees, resulting in a through-length and gapless lock seam, ensuring good waterproofing effect of the lock seam. Of course, the bending degree of the lock seam can also be increased to achieve better waterproof performance. To prevent the edge-locking structure 22 from affecting the bearing platform, the edge-locking structure 22 can perform the edge-locking operation downward to avoid the plane where the bearing platform is located. The two sides of the roof panel adopt a waterproof method of 360-degree (and above) gapless lock seam, and at the same time, the limiting structure 21 is provided to provide a wind-resistant bending bearing surface 33. The connecting bracket 30 is used for wind resistance, and the wind resistance requirement and the waterproof function of the edge-locking structure 22 are separately processed. The lock seam of the edge-locking structure 22 avoids the connecting bracket 30, so that there is no thickness difference between the lock seam of the connecting bracket 30 and the roof panel, thereby achieving a better waterproof effect of the lock seam. At the same time, the wind-resistant bracket is buckled with the limiting structure 21 on the roof panel to restrain the roof panel, achieving the purpose of wind resistance of the roofing system against wind-lifting.

[0058] At the same time, see Figure 5, the photovoltaic module 50 can be assembled on the bearing platform. The photovoltaic module 50 is assembled on two bearing platforms and can also be installed across multiple bearing platforms. The photovoltaic module 50 includes but is not limited to being connected to the bearing platform by means of bonding. For example, an adhesive layer is provided between the bearing platform and the photovoltaic module 50. The adhesive layer can be an adhesive, a tape. The adhesive can be a silicone structural adhesive or other materials, and the tape can be a pressure-sensitive adhesive or a tape of other materials. When bonding the photovoltaic module 50 to the bearing platform, the adhesive layer can be provided only on the bearing platform, or only on the back of the photovoltaic module 50, or on both the bearing platform and the back of the photovoltaic module 50.

[0059] Continue to refer to Figure 1 and Figure 2 , one implementation of the edge-locking structure 22 and the limiting structure 21 is that the edge-locking structure 22 is located at one end of the bearing section 23 away from the limiting structure 21. The limiting structure 21 is located between the bearing section 23 and the main body section 10. The position of the edge-locking structure 22 is far from the position where the limiting structure 21 is located, so that when the edge-locking operation is performed on the edge-locking structure 22, the formed lock seam can be far from the limiting space formed by the limiting structure 21, that is, far from the connecting bracket 30, so that the wind resistance requirement of the roof panel and the waterproof function of the edge-locking structure 22 are separately processed, and the two do not interfere with each other, so that both the waterproof effect of the lock seam and the wind resistance effect of the roof system reach good effects.

[0060] Continue to refer to Figure 1 and Figure 2 , one implementation of the limiting structure 21 is that the limiting structure 21 is a groove structure formed by being recessed in the direction of the other side segment 20. In this setting method, the groove structures on the two side segments 20 extend in opposite directions, that is to say, the groove structure extends into the space enclosed by the two side segments 20. The groove structure can accommodate the limiting plate 322 of the connecting head 32, and cooperate with the limiting plate 322 to restrict the roof panel to prevent the position and state of the roof panel from changing. The bearing section 23 is a straight structure, and the straight structure can better provide support for the photovoltaic module 50, so that the photovoltaic module 50 is more stable when arranged on the bearing platform.

[0061] Furthermore, to make the limiting effect between the groove structure and the limiting plate 322 better, continue to refer to Figure 1 and Figure 2, the groove structure includes a first side 211 and a second side 212. The first side 211 is the side away from the bearing section 23, and the first side 211 gradually inclines towards the plane where the main body section 10 is located. In this setting, the first side 211 extends downward towards the plane where the main body section 10 is located. When the roof panel has an upward movement tendency under windy conditions, the downward-extending first side 211 cooperating with the limiting plate 322 is more conducive to applying a downward force to the roof panel, thereby better avoiding the upward movement of the roof panel.

[0062] Further, according to different requirements, the first side 211 and the second side 212 are arranged in parallel or at an angle. See Figure 9 and Figure 10 , the first side 211 and the second side 212 are arranged in parallel, and there is also a space for accommodating the limiting plate 322 between the first side 211 and the second side 212. In this setting, the connecting bracket 30 can omit the bearing frame 34, reducing the height of the roofing system so that the roofing system can meet more working condition requirements.

[0063] To further improve the strength of the roof panel, a plurality of reinforcing ribs are provided on the main body section 10, and the extending directions of the reinforcing ribs intersect with the length direction of the main body section 10. The reinforcing ribs can be formed on the main body section 10 by rolling or stamping processes. One, two or more reinforcing ribs can be provided. When two or more reinforcing ribs are provided, the intervals between adjacent reinforcing ribs can be equal or unequal. As the number of reinforcing ribs increases, the strength of the roof panel will also increase accordingly. In the embodiments of the present invention, the reinforcing ribs include but are not limited to shapes such as long strip, trapezoid, cross, etc. Further, in order to achieve a better strengthening effect, the extending directions of the reinforcing ribs are perpendicular to the length direction of the main body section 10.

[0064] Further, to enable the roof panel to better support the photovoltaic module 50, for example, the roof panel can provide support for the photovoltaic module 50. See Figure 9 and Figure 10 , in the embodiments of the present invention, a convex rib 11 protruding in the direction from the second surface to the first surface is provided in the middle area of the main body section 10. The convex rib 11 has a support surface 111 flush with the bearing section 23. The convex rib 11 can be formed on the main body section 10 by rolling or stamping processes. One, two or more convex ribs 11 can be provided. The photovoltaic module 50 can be supported by the end of the convex rib 11 away from the main body section 10. At the same time, the strength of the roof panel can be further enhanced through the convex rib 11. Further, a plurality of reinforcing ribs are evenly arranged side by side at positions on the main body section 10 different from the convex rib 11, and the outward convex direction of the reinforcing ribs is the same as the outward convex direction of the convex rib 11.

[0065] Based on the roof panel in the above embodiments, see Figure 3 and Figure 4The embodiment of the present invention further provides a roof system, including: a plurality of roof panels and a plurality of connecting brackets 30. The roof panels are the roof panels in the above embodiment, and the implementation of the connecting brackets 30 can refer to the content in the above embodiment, which will not be repeated here.

[0066] See also Figure 3 and Figure 4 First, fix the connecting bracket 30 on the roof purlin 40, and then assemble the roof panel on the connecting bracket 30. After the roof panel and the connecting bracket 30 are assembled, the relative limiting structures 21 on the two adjacent roof panels can be enclosed to form a limiting space, and the relative locking structures 22 can be locked with each other. After the roof panel is assembled, its main section 10 is carried on the bearing surface 33 of the connecting bracket 30, and the connecting head 32 on the connecting bracket 30 is located in the limiting space. The limiting space provides a curved bearing structure for wind resistance for the roof panel, and the curved bearing structure is connected to the connecting bracket 30. When the roof panel is "lifted up" in a windy environment, the curved bearing structure cooperates with the connecting bracket 30 to resist the "lifting up" together, ensuring that the roof panel remains stable, thereby significantly improving the wind resistance of the roof panel and the roof system formed by it.

[0067] After the adjacent roof panels are assembled, the locking edge structure 22 on one side of the roof panel can be locked with the locking edge structure 22 on the other side of the adjacent roof panel. The locking method includes but is not limited to wrapping one locking edge structure 22 with another locking edge structure 22 and bending it inward 360 degrees, so that the locking seam is a full-length gap-free locking seam to ensure a good waterproof effect of the locking seam. Of course, the degree of bending of the locking seam can also be increased to achieve better waterproof performance. In order to prevent the locking edge structure 22 from affecting the load-bearing platform, the locking edge structure 22 can be locked downward to avoid the plane where the load-bearing platform is located. The two sides of the roof panel adopt a 360-degree (or more) gapless locking seam waterproofing method, and a limiting structure 21 is set to provide a wind-resistant curved bearing surface 33. The connecting bracket 30 is used for wind resistance, and the wind resistance requirement and the waterproof function of the locking edge structure 22 are handled separately. The locking seam of the locking edge structure 22 avoids the connecting bracket 30, so that there is no thickness difference between the locking seam of the connecting bracket 30 and the roof panel, so that the locking seam waterproofing achieves a better effect. At the same time, the wind-resistant bracket is buckled with the limiting structure 21 on the roof panel to restrain the roof panel, thereby achieving the purpose of wind-resistant roofing system.

[0068] Also, see Figure 5 The roof system further includes a photovoltaic module 50, which is connected to a bearing platform on the roof panel. The photovoltaic module 50 can be mounted on a bearing platform, mounted on two bearing platforms, or installed across multiple bearing platforms. The photovoltaic module 50 includes but is not limited to being connected to the bearing platform by bonding.
