But the elastic modulus of aluminum profile is low and the cost is high, and the price is much higher than that of carbon steel material. Carbon steel material cannot be extruded like aluminum profile, and is usually used as track by punching holes on C-shaped steel up and down, but because of the diversity of component specifications and the difference of column span, C-shaped steel needs to make different number of holes and hole positions according to the different needs of actual scheme on site, resulting in low versatility of carbon steel track.

[0025] The specific embodiment of the utility model is described below with reference to the drawings. In order to fully understand the utility model, many details are described below, but the utility model can be realized without these details for those skilled in the art.

[0026] As Figure 1 And Figure 2 The box-shaped track of the photovoltaic support is made of a plate material through a roller forming process. The plate material is a carbon steel plate, especially a carbon steel plate plated with an alloy plating layer on the surface, and the alloy plating layer includes but is not limited to zinc-aluminum-magnesium.

[0027] As Figure 1 And Figure 2 The box-shaped track includes an upper surrounding surface 11, one side surrounding surface 12, a lower surrounding surface 13 and the other side surrounding surface 12, which are sequentially connected to form a box-shaped structure. During processing, the plate material is bent into the upper surrounding surface 11, the one side surrounding surface 12, the lower surrounding surface 13 and the other side surrounding surface 12 along the width direction through the roller forming process, and the two ends of the plate material in the width direction are arranged on the lower surrounding surface 13 and welded with each other, thereby forming a welding node 130.

[0028] The specific structure of the welding node 130 is that the plate material is provided with a fourth bending section 131 and a first U-shaped bending section 132 which are sequentially connected at one end in the width direction through the roller forming process, and is provided with a second U-shaped bending section 133 at the other end in the width direction; the first U-shaped bending section 132 and the second U-shaped bending section 133 are mutually engaged and welded, and the fourth bending section 131 is attached to the bending part of the second U-shaped bending section 133, thereby forming the welding node 130.

[0029] Of course, the welding node 130 can also be arranged on other surrounding surfaces.

[0030] As Figure 1 And Figure 2 The upper surrounding surface 11 is provided with a first connecting part 110 for fixing and assembling the photovoltaic plate 4.

[0031] Specifically, the first connecting part 110 is a pre-embedded groove, and the cross-sectional inner profile thereof is in the shape of an inverted T. The pre-embedded groove is arranged along the length direction of the box track, i.e., the length direction of the plate, and is made of the plate through a roll forming process.

[0032] As shown in Figures 1-4 , during use, a plurality of box tracks 1 are arranged at intervals to form a support frame, and a plurality of photovoltaic panels 4 are arranged in the support frame and are locked by the connecting assembly. Taking the installation of the photovoltaic panel at the edge as an example, the connecting assembly includes a screw, a nut, and a second pressing block 5. First, a plurality of screws (or nuts) are placed in the pre-embedded groove as the first connecting part 110; then, the photovoltaic panel 4 is placed on the plurality of box tracks 1, and the second pressing block 5 is locked to the pre-embedded groove of the box track 1 by the nut cooperating with the screw, so that the upper pressing plate 51 of the second pressing block 5 abuts against the upper end surface of the photovoltaic panel 4, and the lower pressing plate 52 abuts against the upper surrounding surface 11 (specifically, the pre-embedded groove) of the box track 1, thereby locking the photovoltaic panel 4 to the box track 1. Since the pre-embedded groove is arranged along the length direction, the second pressing block 5 can be locked at any position by the bolt according to the installation needs.

[0033] Of course, the first connecting part 110 can also be a plurality of through holes, and the box track 1 can also be locked to the support beam 2 by cooperating with the connecting assembly (including the first pressing block 3 and the bolt) and the threaded hole. However, compared with the first connecting part 110 composed of the pre-embedded groove, the position of the through hole is fixed, and the versatility is poor.

[0034] As shown in Figure 1 and Figure 2 , the side surrounding surface 12 is provided with a groove 120 through a roll forming process, the groove 120 is arranged along the length direction of the box track 1, and the lower side wall of the groove 120 is inclined downward from the groove opening to the groove bottom or is arranged horizontally.

[0035] Specifically, the plate is made of the first connecting section 121, the first bending section 122, the second bending section 123, the third bending section 124, and the second connecting end 125 connected in sequence from top to bottom through a roll forming process. The first connecting section 121 is connected with the upper surrounding surface 11; the groove 120 is composed of the first bending section 122, the second bending section 123, and the third bending section 124; and the second connecting section 125 is connected with the lower surrounding surface 13.

[0036] As shown in Figure 1 and Figure 2 , the upper side wall of the groove 120 is inclined downward from the groove opening to the groove bottom. Specifically, the upper side wall of the groove 120 is composed of the first bending section 122.

[0037] As shown in Figure 1 and Figure 2As shown, the lower sidewall of the groove 120 slopes downwards from the groove opening to the bottom. Of course, the lower sidewall of the groove 120 can also be horizontal. Specifically, the lower sidewall of the groove 120 is formed by a third bent section 124.

[0038] like Figure 1 and Figure 2 As shown, the upper and lower sidewalls of the groove 120 are both inclined downwards from the groove opening to the bottom of the groove, and with the horizontal as the reference plane, the inclination angle of the upper sidewall is greater than that of the lower sidewall. In this way, the groove opening of the groove 120 is larger than the groove bottom, which facilitates the placement of the first pressure block 3.

[0039] like Figures 1-5 As shown, in use, the box-shaped track 1 is placed on the support beam 2 and the two are locked together by the connecting assembly. Specifically, the connecting assembly includes a first pressure block 3 and bolts (including nuts and screws). One end of the first pressure block 3 is provided with a first abutment portion 31 and a second abutment portion 32, and the other end is provided with a third abutment portion 33. When the first pressure block 3 is locked to the support beam 2 by the bolts, the first abutment portion 31 abuts against the third bent section 124 (i.e., the lower sidewall of the groove 120), the second abutment portion 32 abuts against the second connecting section 125, and the third abutment portion 33 abuts against the upper end face of the support beam 2, thereby locking the box-shaped track 1 to the support beam 2.

[0040] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
