Description

  The present invention relates to a photovoltaic power generation panel gantry, and more particularly to a gantry for firmly attaching the photovoltaic power generation panel.

  In recent years, solar power generation has been developed and improved as a clean energy that can save resources instead of thermal power generation, and has been actively introduced widely. Solar power generation equipment (i.e., solar power generation panels) is generally installed on a flat surface, the roof of a building, or the roof of a house. Usually, a photovoltaic power generation panel is supported at a predetermined inclination angle using a photovoltaic power generation panel mounting base so that sunlight can be received efficiently.

  Since the photovoltaic power generation panel is installed outdoors due to its characteristics, it receives wind from various directions, and upward wind pressure or downward wind pressure acts on the panel. Accordingly, there is a need for a pedestal that is firmly attached so as to withstand wind loads caused by strong winds in a posture in which the photovoltaic power generation panel is inclined.

  In order to satisfy these requirements, usually a strong steel material (for example, C-type steel) is used to assemble a mount with an inclined surface for installing a photovoltaic power generation panel, and pillars, beams, anchors, bolts -The thing assembled using the nut is known (for example, refer patent document 1).

  However, in the case of the photovoltaic power generation panel pedestal disclosed in Patent Document 1, a steel material (for example, C-type steel) such as a building material is used, so that the weight becomes excessively large and a great deal of labor is required for movement. In addition, there is a problem that the load applied to the floor surface during installation is increased.

  By the way, in recent years, square steel (for example, square steel in which both ends are caulked at a corner portion) has been frequently used instead of C-shaped steel. This square steel is lighter and more resistant to twisting than the C-shaped steel, and has a closed cross section, so that the strength is dramatically increased and is advantageous in terms of weight reduction, accuracy (for example, flatness) and cost.
