Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic brackets, and in particular relates to a photovoltaic bracket purlin connection structure for increasing the strength of the purlin connection. Background Art

[0002] At present, photovoltaic bracket C-shaped steel is a bracket material widely used in the field of solar power generation. It has a unique C-shaped cross-sectional shape and excellent mechanical properties. It has the characteristics of corrosion resistance, long life, high strength and high rigidity. It is easy to install, cost-saving, environmentally friendly and energy-saving. During the installation and use of photovoltaic brackets, purlins also use C-shaped steel materials. As one of the main load-bearing parts, the strength of the purlin has a significant impact on the overall stability of the photovoltaic bracket structure. The purlin connector used when connecting the two purlins is a C-shaped material wrapped around the outside of the purlin. This C-shaped connector is generally low in thickness and strength. In the application scenario, when the purlin is subjected to upward tension or downward pressure, the purlin connector is very easy to deform or damage; the announcement number is CN221127165U, a photovoltaic bracket purlin structure that can improve the bearing capacity also has the problem of different force strengths in different directions. Summary of the invention

[0003] The utility model provides a photovoltaic bracket purlin connection structure to solve the problem that the purlin connection parts of the photovoltaic bracket products are often damaged due to tension or pressure when the products are used.

[0004] The utility model describes a photovoltaic bracket purlin connection structure, comprising two purlins and a connecting piece connecting the two purlins; the connecting piece is an equilateral channel steel whose height and leg width are adapted to the inner height and width of the purlins, the outer surface of the connecting piece is tightly attached to the inner surface of the ends of the two purlins, matching bolt holes are provided on the ends where the two purlins are connected and the connecting piece, and the two purlins are fixedly connected by fastening bolts passing through the bolt holes of the purlins and the connecting piece.

[0005] More than two stiffening plates are welded inside the connecting piece.

[0006] Four bolt holes are arranged on the groove bottom plate and the two wing plates of the connecting member, and two by two correspond to the bolt holes at the ends of the two purlins to enhance the stability of the connection.

[0007] The utility model discloses a photovoltaic bracket purlin connection structure, which improves the strength of the purlin connection by adopting high-strength equilateral channel steels embedded in the purlins, thereby solving the problem that the purlin connection is often damaged due to tension or pressure when the photovoltaic bracket product is used; by adding stiffening plates in the equilateral channel steels, the overall stability of the photovoltaic bracket structure is further enhanced; and by adopting bolt connection, the photovoltaic bracket is more convenient to install.
