Firstly, a roof panel used with a bracket is introduced, fig. 1 is a schematic side view of a roof panel in an embodiment of the present invention, and fig. 2 is a schematic perspective view of a roof panel in an embodiment of the present invention, as shown in fig. 1 and fig. 2.

An embodiment of the present invention provides a roof panel, including: a main body section 10 and side sections 20. Wherein, the main body section 10 is provided with a wave crest structure 11, the wave crest structure 11 is provided with a first bearing surface 12 and a limit space 13, and two sides of the wave crest structure 11 are respectively provided with a limit structure 14. The opposite sides of the main body 10 are respectively provided with a side section 20, and each side section 20 is respectively provided with a second bearing surface 21 and a locking structure 22. The lockstitching structure 22 on one side of a roof panel can be locked with the lockstitching structure 22 on the other side of an adjacent roof panel.

According to the technical scheme provided by the embodiment of the invention, referring to fig. 3 and 4, the photovoltaic module 30 can be integrated on the roof panel by the first bearing surface 12 on the peak structure 11 and the second bearing surface 21 on the side section 20. Meanwhile, referring to fig. 5, the limiting structure 14 is arranged on the wave crest structure 11 of the roof panel, the limiting structure 14 is matched with a corresponding support structure, the support structure is a support capable of state conversion, and can also be called as a middle support 40, the roof panel is limited on a roof purline 60, and therefore the roof panel has good wind resistance.

In the embodiment of the present invention, the main body 10 may be a plane or a non-plane, and may be made into a corresponding shape according to different requirements. For example, when a flat surface is used, a convex or concave reinforcing structure may be provided on the flat surface for the purpose of enhancing rigidity and strength. Roofing panels include, but are not limited to, sheet metal that is formed by stamping, rolling, etc., processes that include sheet metal having an anti-corrosive coating on the surface thereof to improve the corrosion resistance of the sheet material, including, but not limited to, steel sheet, and anti-corrosive coatings including, but not limited to, paint coatings, zinc coatings, etc.

The side section 20 and the main body section 10 may be an integrally formed structure, and are manufactured by a bending process or a stamping process. One way of forming the side edge sections 20 is to select a section with a predetermined length at both ends of the main body section 10, and then to bend the main body section 10 upward by a bending process, which is taken as an example of the orientation in fig. 1, thereby forming the side edge sections 20 at both sides. Then, taking the right side section 20 as an example, the side section 20 is bent to the right by a predetermined distance to form a second bearing surface 21, the second bearing surface 21 is bent to form a bent section 23 to form a drainage channel, and the bent section 23 is bent upward to form a locking structure 22.

The peak structures 11 may be formed on the body segment 10 by a rolling or stamping process. The peak structures 11 may be one, two or more, and the photovoltaic panel may be supported by the peak structures 11 away from the first carrying surface 12 of the main body segment 10. Simultaneously, can further strengthen the intensity of roof boarding through crest structure 11. Furthermore, a plurality of reinforcing ribs 15 are uniformly arranged on the main body section 10 side by side at positions different from the convex ribs, and the convex direction of the reinforcing ribs 15 is consistent with the convex direction of the wave crest structure 11.

Referring to fig. 5, when the roofing system is formed by assembling roof panels on roofing purlins 60, the roof panels can also be used with a plurality of support structures, such as middle support 40 used with peak structure 11 and side supports 50 used with lockrand structure 22. The middle support 40 and the side supports 50 are fixedly connected with the roof purline 60 through self-tapping screws respectively, meanwhile, the middle support 40 is connected with the limiting structure 14 on the wave crest structure 11, and the side supports 50 are connected with the locking edge structure 22, so that the roof panel is limited through the middle support 40 and the side supports 50, and the wind resistance of the roof panel is improved.

With continued reference to fig. 5, in the embodiment of the present invention, one implementation manner of the middle support 40 is that the middle support 40 includes a base 41 and a connector 42, and the connector 42 can be disposed in the limiting space 13 and cooperate with the limiting structure 14 to define a relative position between the roof panel and the middle support 40. The base 41 serves to connect with the roof purlin 60 and provides support for the connector 42. The specific implementation manner of the base 41 is not particularly limited herein as long as the above-described functions can be achieved. The connector 42 is arranged in the limiting space 13 and is matched with the base 41 to restrict the position of the roof panel, so that the position and the state of the roof panel are ensured to be stable. Of course, the specific implementation manner of the connection head 42 is not specifically limited herein as long as the above-mentioned functions can be achieved.

Further, in some practical embodiments of the present invention, one way to realize the connection head 42 is that the portion of the connection head 42 engaged with the position-limiting structure 14 is fixed relative to the base 41, and the shape of the connection head 42 matches with the shape of the position-limiting space 13. Another implementation manner of the connector 42 is that the part of the connector 42, which is matched with the limiting structure 14, is rotatable relative to the base 41, the connector 42 has two states, one state is a vertical state, and at this time, the wave crest structure 11 on the roof panel can be conveniently buckled on the connector 42, or in other words, the connector 42 can conveniently extend into the limiting space 13. When the connector 42 is converted from the vertical state to the horizontal state, the connector 42 can be clamped on the limiting structure 14, so that the roof panel is limited by the limiting structure 14.

With continued reference to fig. 1 and 2, to support the photovoltaic device 30, the first supporting surface 12 and the second supporting surface 21 are located on the same plane. Because first bearing surface 12 is located the coplanar with second bearing surface 21, then when installing photovoltaic module 30, the both ends of photovoltaic module 30 coincide respectively the butt on the second bearing surface 21 of both sides, the anastomotic support in middle part of photovoltaic module 30 is on first bearing surface 12, can carry out better bearing to photovoltaic module 30, under the effectual condition of bearing, can reduce the requirement of photovoltaic module 30 self intensity, along with the reduction to self intensity requirement, can reduce the thickness of photovoltaic module 30 self, in order to reduce weight and manufacturing cost. Generally, the thickness of the photovoltaic module 30 itself can be reduced by reducing the thickness of the glass package plate on the front side of the photovoltaic module 30, and as the thickness of the glass package plate on the front side is reduced, the light transmittance of the photovoltaic module 30 is enhanced, and the photoelectric conversion performance is improved accordingly.

Further, one way of connecting the photovoltaic module 30 to the roof panel is that the photovoltaic module 30 is adhered to the first bearing surface 12 and the second bearing surface 21 of the roof panel, for example, the photovoltaic module 30 can be adhered to the first bearing surface 12 and the second bearing surface 21 by an adhesive or an adhesive tape, which has an effect of convenient operation. The adhesive can be a silicone structural adhesive or other materials, and the adhesive tape can be a pressure-sensitive adhesive or other material adhesive tape.

Another way of attaching photovoltaic assembly 30 to a roof panel is to secure photovoltaic assembly 30 to the roof panel by a clip assembly, see fig. 6. One way of achieving the clamp assembly is that the clamp assembly includes a middle clamp 70 assembly and side clamps 71. The middle fixture 70 assembly is connected to the wave crest structure 11 on the roof panel and forms a first clamping structure with the first bearing surface 12 to restrain the photovoltaic assembly 30. The side fixture 71 is connected to the locking edge structure 22 on the roof panel and forms a second clamping structure with the second bearing surface 21 to limit the photovoltaic module 30. Based on the clamping effect of the clamp assembly, the photovoltaic assembly 30 can be effectively fixed, and the stability of the photovoltaic assembly 30 is improved. Further, the mode of bonding can cooperate the use with the anchor clamps subassembly, is about to when photovoltaic module 30 bonds on the roof boarding, and the rethread anchor clamps subassembly is fixed photovoltaic module 30 once more to make photovoltaic module 30's position more stable.

In order to further ensure the drainage function of the roof system, it is possible to provide the side edge sections 20 with bent sections 23, and the bent sections 23 are located between the second bearing surface 21 and the serging structure 22. The bent section 23 is bent downward far from the second bearing surface 21, and rainwater falling onto the roof system can flow away through the bent section 23 to ensure the drainage function of the roof system. Rainwater falling onto the roof panel can flow away through the gap between the main body section 10 and the photovoltaic assembly 30. Meanwhile, a heat dissipation channel can be formed through a gap between the main body section 10 and the photovoltaic module 30, so that air can circulate, and the heat dissipation performance of the roof system can be ensured. Further, in order to ensure that the formed heat dissipation channel has sufficient heat dissipation performance, the distance between the main body 10 and the photovoltaic module 30 may be set according to different requirements, for example, may be greater than 2 cm, and the distance is set so that the heat dissipation channel has sufficient cross-sectional area to ensure sufficient air flow to dissipate heat of the photovoltaic module 30.

With continued reference to fig. 1 and 2, one way to implement the wave crest structure 11 is that the wave crest structure 11 includes a top plate and two side plates, and the top plate is provided with a first bearing surface 12. The limit structure 14 is a groove structure which is positioned on the side plate and is sunken towards the limit space 13. In this arrangement, the groove structures on the two side plates extend in opposite directions, or in other words, the groove structures extend into the limiting space 13 enclosed by the two side plates. The groove structure can accommodate the connector 42 of the middle support 40, and the roof panel can be restrained by matching the connector 42, so that the position and the state of the roof panel are prevented from being changed.

Further, for the spacing effect between spacing recess and the connector is better, continue to refer to fig. 1 and fig. 2, groove structure level extension or gradually towards roof place plane perk. Under this kind of mode of arrangement, groove structure can be better with the connector 42 block on the well support 40, and change the interact power, when the roof boarding under the condition of blowing, has the trend of rebound, and groove structure cooperation connector 42 more is favorable to exerting decurrent effort to the roof boarding to can avoid the roof boarding rebound better.

In order to further improve the strength of the roof panel, the main body section 10 is provided with a plurality of reinforcing ribs 15, and the extending direction of each reinforcing rib 15 intersects with the longitudinal direction of the main body section 10. The ribs 15 may be formed on the body segment 10 by a rolling or pressing process, one, two or more ribs 15 may be provided, and when two or more ribs 15 are provided, the intervals between the adjacent ribs 15 may be equal or unequal. As the number of reinforcing ribs 15 increases, the strength of the roof panel will also increase accordingly. In the embodiment of the present invention, the reinforcing rib 15 includes, but is not limited to, a long bar shape, a trapezoid shape, a cross shape, etc. Further, in order to achieve a preferable reinforcing effect, the extending direction of each rib 15 is perpendicular to the longitudinal direction of the main body section 10.

In the embodiment of the invention, one construction mode of the roof panel is as follows: for convenience of description, taking the orientation in fig. 1 as an example, the left-right direction in fig. 1 is defined as the longitudinal direction of the roof panel, and the direction perpendicular to the paper plane in fig. 1 is defined as the width direction of the roof panel.

During construction, a plurality of support structures are arranged at intervals along the length direction of the roof panel and are fixed on the roof purlines 60 in a fixing mode including but not limited to fixing through self-tapping screws. The plurality of support structures arranged at intervals can be arranged corresponding to different limiting spaces 13, for example, the middle support 40 is arranged corresponding to the limiting space 13 of the wave crest structure 11, and the side supports 50 are arranged corresponding to the overlocking structures 22. Further, for one spacing space 13, the corresponding connected middle support 40 may be one, and one middle support 40 extends along the width direction of the roof panel and penetrates through the whole spacing space 13. The number of the middle supports 40 can also be multiple, and the multiple middle supports 40 are arranged at intervals along the width direction of the roof panel and are connected with the same limiting space 13 correspondingly. In the embodiment of the present invention, an example that one limiting space 13 corresponds to one supporting structure is described, which does not limit the embodiment of the present invention.

Secondly, because the roof panel can be made of metal plates and the side sections 20 have certain elasticity relative to the main body section 10, the roof panel can be clamped between the two side supports 50 in an extrusion mode and is covered and buckled on the middle support 40 through the wave crest structure 11, and the middle support 40 can be connected with the limiting structure 14 after entering the limiting space 13 so as to limit the position of the roof panel.

After assembly, the opposed lockrand structures 22 on two adjacent roof panels can be interlocked. After the roof panel is assembled, the connector 42 on the middle support 40 is located in the limiting space 13, the limiting space 13 provides a limiting structure 14 for resisting wind for the roof panel, and the limiting structure 14 is connected with the middle support 40. When the roof panel is in a wind uncovering condition in a windy environment, the limiting structure 14 is matched with the middle support 40, and the side supports 50 are matched with the locking edge structure 22 to resist wind uncovering together, so that the roof panel is ensured to be stable in state, and the wind resistance effect of the roof panel and a roof system formed by the roof panel is improved remarkably.

Further, after the adjacent roof panels are assembled, the lockstitching structure 22 on one side of the roof panel can be locked with the lockstitching structure 22 on the other side of the adjacent roof panel. The locking mode includes, but is not limited to, wrapping one overlock structure 22 with the other overlock structure 22 and bending inward to obtain a full-length gapless overlock seam, so as to ensure good waterproof effect of the overlock seam, and certainly, the bending degree of the overlock seam can be increased so as to ensure better waterproof performance. The two sides of the roof panel adopt a waterproof mode of gapless seam locking of 360 degrees (and above), and meanwhile, a limiting structure 14 is arranged to provide a wind-resistant bending bearing surface, and a support structure is utilized for wind resistance.

In the embodiment of the present invention, the implementation manner of the support structure includes multiple manners, one of which is that, referring to fig. 7 to 8, one implementation manner of the support structure in the embodiment of the present invention is that, the support structure is a support capable of state transition, and includes: base 41, bracing piece 421, limit baffle 44 and trigger device 423.

The limit stop 44 is the connecting head 42 connected with the limit structure 14. Referring to fig. 11, the trigger device 423 is disposed on the support bar 421, and the trigger device 423 is provided with a limit protrusion 442 matching with the limit groove 441 and a positioning leg 45 matching with the positioning portion.

With continued reference to fig. 7, when the trigger 423 is located at the first position, the limiting protrusion 442 at least partially extends into the limiting groove 441, and the positioning leg 45 is connected to the positioning portion to constrain the limiting baffle 44 to the vertical state. The vertical state of the limit baffle 44 means a state in which the extending direction of the limit baffle 44 is the same as the extending direction of the limit space 13. When the limit baffle 44 is in a vertical state, the bracket can conveniently enter the limit space 13, and further the assembly between the bracket and the wave crest structure 11 is convenient.

With continued reference to fig. 8, when the trigger 423 is located at the second position, the positioning leg 45 is separated from the positioning portion, the limit protrusion 442 is separated from the limit groove 441, and the limit baffle 44 is switched from the vertical state to the horizontal state under the elastic force of the elastic member 4221. The horizontal state of the limit stopper 44 means a state in which the extending direction of the limit stopper 44 intersects with the extending direction of the limit space 13. When limiting baffle 44 is horizontal, can cooperate limit structure 14 on the crest structure 11, inject the roof boarding on roofing purlin 60 to make the roof boarding have good wind resistance, and limiting baffle 44 on the support can be two kinds of states, so that with the installation between the roof boarding.

The connecting portion 411 is used for being connected and fixed with the roof purline 60 so as to fix the position of the whole bracket. For the connection of convenient connecting portion 411, the porose structure of predetermineeing on the connecting portion 411, can realize being connected of connecting portion 411 and roofing purlin 60 through self-tapping screw. The boss 412 is higher than the connecting portion 411 so as to raise the relative height of the support rod 421, so that the support rod 421 is not connected with the roof purlin 60, and meanwhile, an avoiding space is provided for the downward movement of the positioning support leg 45. The supporting rod 421 is disposed on the boss 412, the base 41, the triggering device 423 and the limiting baffle 44 are integrated together through the supporting rod 421, and the limiting baffle 44 can rotate around the supporting rod 421, so that the vertical state and the horizontal state can be switched.
