According to the actual situation of the construction site, the cross-sectional size is reasonably selected.

[0030] The utility model takes the installation of a 665Wp photovoltaic module (with a size of 2384mm×1303mm) as an example to illustrate the specific method.

[0031] The 665Wp photovoltaic module adopts a double-column and double-diagonal brace foundation. The front column 16 and the rear column 20 are 60x3.0 steel pipes, the front diagonal brace 17 and the rear diagonal brace 18 are channel steel C50x40x10x2.0, the diagonal beam 19 is channel steel C80x40x15x2.2, the first purlin 12, the second purlin 13, the third purlin 14 and the fourth purlin 15 are channel steel C90x50x15x2.0.

[0033] First, the heights of the first crossbar 1 and the second crossbar 2 from the ground are determined according to the heights of the third purlin 14 and the fourth purlin 15, so that construction workers can stand and construct. Then, the lengths of the first crossbar 1, the second crossbar 2, the vertical bar 3, and the diagonal brace 4 are determined in sequence. The length of the anti-sliding block 6 is the same as the cross-sectional width of the second crossbar 2, and the function of the anti-sliding block is to prevent the pedal 21 from sliding off.

[0034] Then, the first cross bar 1, the second cross bar 2, the vertical bar 3, the diagonal brace 4 and the anti-sliding block 6 are welded together in sequence with E43 welding rods, and 6 mm fillet welds are used for four-sided welding.

Construction workers can move forward along the pedals to install and fix the photovoltaic components in turn.

[0037] After the entire device is completed, the entire device is directly clamped on the front diagonal brace 17 and the rear diagonal brace 18 of the photovoltaic bracket through a U-shaped connector, and then a pedal is placed.
