Purline assembly and photovoltaic support

By introducing reinforcing members into the purlin assembly, covering the purlin flanges and abutting against the limiting part to form a closed cross section, the problem of purlin deformation under wind pressure is solved, thereby improving the strength of the purlins and simplifying installation, and enhancing the structural stability of the photovoltaic support.

AI Technical Summary

Technical Problem

The zigzag purlins in existing photovoltaic brackets have insufficient bending and torsional stiffness when subjected to lateral wind pressure or external loads, causing the flanges connecting adjacent photovoltaic modules to shift, resulting in the purlin openings shrinking inward or expanding outward, thus damaging the photovoltaic brackets.

Method used

The system employs purlin modules and photovoltaic brackets, including purlins and reinforcing members. The purlins consist of a base plate and a side plate, with the side plate bent to form a wing plate. The reinforcing members include a mounting part and a limiting part. The mounting part covers the wing plate, and the limiting part abuts against the wing plate to form a closed cross section, thereby increasing the contact area between the purlin and the photovoltaic module and preventing purlin deformation.

Benefits of technology

Improve the strength and fixing effect of purlins, reduce purlin deformation, enhance structural reliability, simplify the installation process, improve construction efficiency, and enhance resistance to deformation.

Abstract

The purline assembly comprises a purline and a reinforcing piece, the purline comprises a bottom plate and two side plates, the two side plates are connected to the two ends of the bottom plate respectively, and the ends, away from the bottom plate, of the two side plates are bent towards the sides away from each other to form wing plates; the reinforcing piece comprises a mounting part and limiting parts, the two limiting parts are arranged at the two ends of the mounting part in the first direction, the mounting part is at least partially attached to the two wing plates, and at least parts of the sides, away from each other, of the two wing plates abut against the limiting parts. The purline assembly and the photovoltaic support are matched in size and easy to install, the field construction efficiency is improved, the structure is stable, and the non-deformability is high.
