[0025] Embodiment 1

[0026] As Figures 1 - 4As shown in the figure, an inclined beam installation structure mainly includes a column 3 with a notch and a connecting part 7 opened at the top, and an inclined beam 6. The inclined beam 6 is fixedly connected to the notch at the top of the column 3. A backing plate 8 is arranged between the connecting part 7 and the inclined beam 6. The inclined beam 6, the backing plate 8, and the connecting part 7 are fixedly connected by screws. The notch at the top of the column 3 is preferably formed by cutting. By installing the inclined beam 6 through the notch at the top of the column 3 and cooperating with the backing plate 8 to strengthen the connecting part 7 of the structure, it is possible to avoid deformation of the connecting part 7 due to excessive load. The inclined beam 6, the backing plate 8, and the connecting part 7 are fixedly connected by a single screw to form a stable connection structure. Compared with the prior art method of additionally installing a connecting piece at the top of the column 3, the construction cost and material cost of fitting installation are reduced, raw materials can be saved, and the construction cost can be reduced. Compared with the form of grooving at the top of the column, reinforcement is carried out through the backing plate 8 and screws, and the structural strength at the connecting part 7 is improved.

[0027] In some alternative embodiments, the backing plate 8 is welded to the connecting part 7. A bending part 13 is arranged at the top of the backing plate 8. The backing plate 8 is designed in an L shape. The top of the backing plate 8 is installed at the upper part of the column 3 through the bending part 13 to increase the contact area between the inclined beam 6 and the backing plate 8. The backing plate 8 is provided with a first round hole 15 for the screw to pass through. A second round hole is opened on the side of the connecting part 7 away from the backing plate 8. After the screw passes through the second round hole, it is locked by a nut.

[0028] In addition, the notch at the top of the column 3 and the connecting part 7 can be directly prefabricated and processed in the factory, avoiding on-site construction. The welding of the backing plate 8 can also be directly completed inside the factory.

For example, when the column 3 is set as a round tube, both the connecting part 7 and the clamping ring 14 are arc-shaped. When the column 3 is set as a rectangular tube, both the connecting part 7 and the clamping ring 14 are set as U-shaped.

[0030] In some alternative embodiments, a plurality of first kidney-shaped holes 9 are opened on the inclined beam 6. By connecting the first round hole 15 with the first kidney-shaped holes 9 at different positions, the installation angle of the inclined beam 6 is adjusted. The screw passes through the first kidney-shaped hole 9, the first round hole 15, and the second round hole in sequence to fixedly connect the inclined beam 6, the backing plate 8, and the connecting part 7.

[0031] Optionally, the column 3 is set as a round tube or a rectangular tube, and the inclined beam 6 is set as one of a C-shaped steel, a U-shaped steel, and an angle steel.

A number of second kidney-shaped holes for adjusting the connection positions with the first diagonal brace 4 and the second diagonal brace 5 are provided at both ends of the inclined beam 6.

[0034] In some alternative embodiments, a purlin 10 is fixedly connected to the top of the inclined beam 6, and the purlin 10 is used for installing photovoltaic modules 11.
