The characteristics of small axial pull-out force and large shearing resistance of the riveting convex points of the rivet-free press riveting are perfectly matched with the stress mode of the purline.

As shown in fig. 3, the U-shaped purlin reinforcing plate is divided into four rivet-free press-riveting salient point areas which are symmetrically arranged at the end part of the U-shaped purlin reinforcing plate and the position close to the end part of the U-shaped purlin reinforcing plate, and when the photovoltaic tracker operates and bears external force load, the stress of a single riveting salient point is extremely small, so that the safety of the supporting structure is guaranteed; and a plurality of riveting salient points are distributed in each group of riveting salient point areas. The rivet-free press-riveting salient points of the U-shaped purline reinforcing plate are formed to be inwards concave at the outer surface of the U-shaped purline reinforcing plate, so that damage caused in the transportation and installation processes can be effectively avoided. The recess is coated with antirust paint.

Specifically, referring to fig. 4, the equipment extrudes the rivet-free riveting convex points with the depressions on the U-shaped purlin reinforcing plate 120 into the n-shaped purlins 110, so that small depressions protruding inwards are formed on the surface of the n-shaped purlins 110, and the small depressions are just used for matching with the rivet-free riveting convex points 121 on the U-shaped purlin reinforcing plate 120 to form limiting fixation of the rivet-free riveting convex points 121.
