The present application is exemplified by a profiled steel sheet in which the splice plate body 100 is a profiled steel sheet body and the first side 110 and the second side 120 are opposite sides of the profiled steel sheet, respectively, for example, when the profiled steel sheet is installed on a roof, the first side 110 and the second side 120 of the profiled steel sheet can be regarded as the top and bottom of the profiled steel sheet due to the inclined arrangement of the roof.

The first male rib side 111 is formed by extending the first side 110, and then the first male rib side 111 is formed by extending the first male rib side 111 to form a first male rib top 112, wherein in operation, the first male rib side 111 is at an angle to the splice plate body 100, and the first male rib top 112 is at an angle to the first male rib side 111 such that the first male rib top 112 is parallel or substantially parallel to the splice plate body 100.

In addition, when water is introduced between the first male rib side 111 and the second female rib side 123 due to capillary action after the first sealing member 810 is partially or completely deactivated due to long use time, the capillary cavity 200 is also used as a second waterproof measure, so that the risk of water leakage can be effectively reduced.

According to the application, the first male rib side edge 111 and the first male rib top edge 112 are arranged on the first side edge 110 of the lapping plate main body 100, the first female rib side edge 121, the first female rib top edge 122 and the second female rib side edge 123 are arranged on the second side edge 120 of the lapping plate main body 100, wherein the first groove 101 is arranged at the joint of the first male rib side edge 111 and the first male rib top edge 112, when two adjacent lapping plate main bodies 100 are lapped, the first female rib top edge 122 of one lapping plate main body 100 is lapped and matched with the first male rib top edge 112 of the other lapping plate main body 100, the second female rib side edge 123 is jointed with the first male rib side edge 111, so that the first female rib top edge 122, the second female rib side edge 123 and the first groove 101 can be jointed to form the capillary cavity 200, and even if water enters the capillary suction force is stopped at the joint of the second female rib side edge 123 and the first male rib side edge 111 due to capillary phenomenon, and water is further discharged through the capillary cavity 200 and an external drainage system, so that water leakage can be effectively reduced.

In some alternative embodiments, the first male rib side 111, the first male rib top edge 112, the first female rib side 121, and the first female rib top edge 122 enclose a cable space 700 for the photovoltaic cable routing.

In practice, the first male rib side 111 and the first male rib top edge 112 may be regarded as being higher than the bent edge of the splice plate body 100, and likewise, the first female rib side 121, the first female rib top edge 122 and the second female rib side 123 may be regarded as being higher than the bent edge of the splice plate body 100, and when the first female rib top edge 122 is overlapped on the first male rib top edge 112, the first male rib side 111, the first male rib top edge 112, the first female rib side 121 and the first female rib top edge 122 are integrally formed into a reverse groove shape, that is, the longitudinal sections of the first male rib side 111, the first male rib top edge 112, the first female rib side 121 and the first female rib top edge 122 are trapezoidal or substantially trapezoidal, and the inner space of the reverse groove shape is the cable space 700, and the cable space 700 is used for routing a photovoltaic cable.

In some possible embodiments, the height of the cable space 700 may be a vertical height between the first male rib top edge 112 and the splice plate body 100, or the height of the cable space 700 may be a vertical height between the first female rib top edge 122 and the splice plate body 100, where the height of the cable space 700 may be set according to a diameter of a cable or a size of space required for a cable routing and a connection terminal, without limitation.

In some alternative embodiments, the first male rib top edge 112 is configured to mate with the mounting bracket 300 for secure mounting to a target member by the mounting bracket 300, the mounting bracket 300 having a cable space 700.

In practice, the fixing bracket 300 is used to support the top edge 112 of the first male rib, and the photovoltaic integral profiled steel sheet is taken as an example and is mounted on the roof purline 400 through the fixing bracket 300. Illustratively, the longitudinal section of the fixing bracket 300 is inverted V-shaped or inverted U-shaped, and both sides of the opening of the V-shaped or inverted U-shaped extend to form mounting feet, which can be fixed to the purline 400 by bolts 500 or self-tapping screws, so that the fixing bracket 300 is inverted on the purline 400. Then, the male rib peak is fastened on the fixing bracket 300, at this time, the first male rib side 111 is tightly attached to one side of the fixing bracket 300, the first male rib top edge 112 is tightly attached to the top edge of the fixing bracket 300, and then the female rib peak is fastened on the male rib peak, at this time, the second female rib side 123 is tightly attached to the first male rib side 111, the first female rib top edge 122 is tightly attached to the first male rib top edge 112, the first female rib side 121 can be tightly attached to the other side of the fixing bracket 300, and of course, a certain distance exists between the first female rib side 121 and the other side of the fixing bracket 300, so that the male rib peak and the female rib peak can be lapped on the fixing bracket 300.

Because the longitudinal section of the fixing bracket 300 is inverted V-shaped or inverted U-shaped, a certain space is provided between the fixing bracket 300 and the purline 400, and the space can be used for cable routing, that is, the space between the fixing bracket 300 and the purline 400 can be regarded as the cable space 700. Similarly, the first male rib side 111, the first male rib top 112, the first female rib top 122 and the first male rib side 111 are in a reverse-buckle bowl shape, that is, a cable space 700 may be formed between the first male rib side 111, the first male rib top 112, the first female rib top 122, the first male rib side 111 and the fixing bracket 300, or a cable space 700 may be formed between the first female rib top 122, the first male rib side 111 and the fixing bracket 300, so as to facilitate cable routing.

In some possible embodiments, the distance between the lapping plate body 100 and the purline 400 may be increased by the fixing bracket 300, so as to form a cavity between the lapping plate body 100 and the purline 400, and of course, if the purline 400 is further provided with a waterproof layer and/or an insulating layer, it may be considered that a cavity is formed between the lapping plate body 100 and the waterproof layer and/or the insulating layer. The cavity can be used for ventilation, when an example photovoltaic integrated profiled steel sheet is installed on a roof, ventilation holes (not shown in the figure) are formed in the ridge and the eave, the ventilation holes are communicated with the cavity, and the chimney effect is utilized for ventilation, so that the temperature of the photovoltaic module 600 can be effectively reduced, and the power generation efficiency of the photovoltaic module 600 is improved.

In some embodiments, a second groove 310 may be disposed on the fixing support 300, where the second groove 310 cooperates with the first groove 101, so as to increase the contact area between the fixing support 300 and the male rib peak (the first male rib side 111 and the first male rib top 112), and make the fixing support 300 more fit with the male rib peak, and make the installation more stable and reliable.

In some alternative embodiments, the first female rib top edge 122, the first male rib top edge 112, and the securing bracket 300 are fixedly coupled by bolts 500. The first female rib top edge 122, the first male rib top edge 112 and the fixing bracket 300 are provided with mounting holes (not shown), which may be through holes, through which one end of the bolt 500 is passed to be engaged with a nut to mount and connect the first female rib top edge 122, the first male rib top edge 112 and the fixing bracket 300 together. In some possible embodiments, the mounting holes may also be internally threaded holes, with which the bolts 500 are threadedly engaged to mount and connect the first female rib top edge 122, the first male rib top edge 112, and the fixing bracket 300 together, with a stable and reliable mounting.

In operation, the first male rib top edge 112 extends to form a V-shaped or U-shaped water guide channel 113, with the water guide channel 113 and the first female rib top edge 122 forming a water guide channel 115. In the use process, because the first female rib top edge 122, the first male rib top edge 112 and the fixing support 300 are fixedly connected through the bolts 500, water seepage possibly exists when the bolts 500 are perforated, namely, water possibly fills the mounting holes and stretches into the first female rib top edge 122, then flows into the water guide groove 113 and is discharged by the water guide groove 113, for example, the water guide groove 113 is connected with an external drainage system so as to discharge water seepage to the external drainage system and then is discharged by the external drainage system, and the waterproof effect is further improved.

In some alternative embodiments, the first female rib top edge 122 is provided with a third groove 124, the third groove 124 being configured to limit the first male rib top edge 112 to conform the first male rib side edge 111 to the second female rib side edge 123.

When the female rib peak is buckled on the male rib peak, the first male rib top edge 112 is attached to the first female rib top edge 122, and the first male rib side edge 111 is tightly attached to the second female rib side edge 123 due to the limiting effect of the third groove 124 on the first male rib top edge 112, and the mounting holes of the first female rib top edge 122, the first male rib top edge 112 and the mounting bracket can be directly aligned to be matched with the bolt 500, so that the mounting is convenient and quick.

In some alternative embodiments, the water guide 113 is formed with a third male rib side 114 extending, the third male rib side 114 being adapted to fit the first female rib side 121, and a second seal 820 being provided between the third male rib side 114 and the first female rib side 121.

In practice, the first male rib side 111 and the third male rib side 114 are the outermost sides of the male rib peak, and likewise, the first female rib side 121 and the second female rib side 123 are the outermost sides of the female rib peak, and when the female rib peak is snapped onto the male rib peak, the first male rib side 111 and the first female rib side 121 are in close contact, and simultaneously the third male rib side 114 and the second female rib side 123 are in close contact, and the waterproof effect can be further improved by providing the second sealing member 820 between the third male rib side 114 and the first female rib side 121.

In some possible embodiments, the number and width of the first and second seals 810 and 820 may be specifically set as desired, without limitation.
