Description

  The present invention relates to a solar cell array installation apparatus that is installed on a flat roof, such as a flat roof and an inclined land, and a flat roof such as a building roof, particularly as a large-scale photovoltaic power generation facility such as a mega solar.

In recent years, from the viewpoints of environmental protection, resource saving, CO ₂ reduction, etc., large-scale photovoltaic power generation facilities such as mega-solar power generation systems, where a large number of solar cell arrays are arranged side by side on a flat roof such as the ground or a building roof, including flat and sloping land Is spreading. However, in general, the solar cell array is heavy in the form of a large panel having a short side number of m and a long side number of m to several tens of meters in which a plurality of solar cell modules are arranged in a plane, and is more predetermined than the light receiving efficiency surface. Because it is easy to receive wind pressure by placing it at an inclination angle, the installation part needs to have a large support strength and wind pressure strength, and it is also required to reduce the overall weight, facilitate installation work, reduce costs, etc. .

  Conventionally, as a means for installing such a solar cell array on the ground or on a flat roof, a method of constructing a frame made of a steel plate or the like based on a concrete pile or base and installing the solar cell array on the frame is often used. ing. As the gantry, a plurality of support columns are projected along the longitudinal direction (left-right direction) of the solar cell array at intervals, and the upper end portion of each support column is in the short side direction of the gantry frame that supports the solar cell array. A structure (Patent Document 1) in which an inclined arm is connected between the middle portion of each column and the front side of each vertical beam or both front and rear sides thereof, while being connected to an intermediate position of the vertical beam along the (front-rear inclination direction) A structure in which the frame of the solar cell array is supported by pillars arranged in the front-rear and left-right directions, and diagonal and horizontal reinforcing bars are connected between the pillars adjacent in the front-rear and left-right directions (Patent Document 2) is representative.
