In addition, since the profiled metal sheet 20 can be fixed on the support 30, the edge portion of the profiled metal sheet 20 is fixed, so that the probability of the problem of edge warping of the photovoltaic module 10 can be reduced.

In addition, the photovoltaic module 10 is generally large in area, and after the photovoltaic module 10 is adhered to the profiled metal sheet 20, the middle part of the photovoltaic module 10 has a large pressure on the profiled metal sheet 20, so that the edges of the photovoltaic module 10 and the profiled metal sheet 20 are easily warped, and the wind uncovering resistance of the roof formed by the photovoltaic module 10 and the profiled metal sheet 20 is poor. In the embodiment of the present application, the profiled metal sheet 20 is fixed on the support 30, so that the edge of the profiled metal sheet can be fixed, and at this time, the profiled metal sheet 20 and the photovoltaic module 10 can be fixed together more firmly, so that the wind uncovering resistance of the roof formed by the profiled metal sheet 20 and the photovoltaic module 10 is increased.

In addition, referring to fig. 5, in some embodiments, a schematic view of a supporting member provided in the embodiments of the present application is shown, as shown in fig. 5, a supporting member 30 includes a connecting plate 31, two fixing plates 32, and two supporting plates 33, the connecting plate 31 includes opposite first and second sides, the fixing plates 32 are respectively disposed at the first and second sides, and the fixing plates 32 are used for being connected to the purlins 100. The connecting plate 31 further comprises opposite third and fourth sides, where support plates 33 are provided, respectively, the support plates 33 being adapted to be connected to the profiled metal sheet 20.

Because the supporting members 30 include the connecting plates 31, the fixing plates 32 are respectively disposed at the first side and the second side of the connecting plates 31, when the two ends of the supporting members 30 are respectively connected to two adjacent purlins 100, the fixing plates 32 at the first side and the second side can be respectively fixed to two adjacent purlins 100. Since the support plates 33 are provided at the third side and the fourth side of the connecting plate 31, respectively, the profiled metal sheet 20 can be fixed to the support plate 33 at the third side or the support plate 33 at the fourth side by the support 40 when the profiled metal sheet 20 is fixed to the support 30.

Since the support plate 33 at the third side is provided with the second through hole, and the third side is a side close to the profiled metal sheet 20, when the profiled metal sheet 20 is connected to the support plate 33 at the third side, a tapping screw can be passed through the second through hole so that the third side is connected to the profiled metal sheet 20. That is, by forming the first through hole on the fixing plate 32 and forming the second through hole on the supporting plate 33 at the third side, it is convenient for the two ends of the supporting member 30 to be respectively connected with the two adjacent purlins 100, and it is convenient for the profiled metal sheet 20 to be connected with the supporting plate 33 at the third side.

It should be noted that, in the gravity direction, the supporting plate 33 at the third side is at the same height as the connecting side in the purlin 100, which means that the upper surface of the supporting member 30 is at the same height as the upper surface of the purlin 100, and since the third side is a side close to the profiled metal sheet 20, the height of the third side may be the height of the upper surface of the supporting member 30, and the height of the connecting side may be the height of the upper surface of the purlin 100.

In addition, in some embodiments, the connecting side is provided with a third through hole.
