Large scale solar power generation facilities are spreading. However, in general, a solar cell array is large and heavy with a short side number m and a long side number m to several tens of meters in which a plurality of photovoltaic power generation panels (solar cell modules) are arranged in a plane, and has a light receiving efficiency. It is easy to receive wind pressure by being placed at a predetermined inclination angle from the surface, and it is also susceptible to shaking due to earthquakes.Therefore, a large structural strength is required. It is also necessary to cope with equal settlement, etc. In addition, it is required to facilitate installation and reduce costs.

  Conventionally, as a means of installing such a solar cell array on the ground or on a flat roof, a method of constructing a base made of a steel plate or the like based on a concrete pile or base and installing a photovoltaic power generation panel on this base is often used. Has been. As the gantry, a plurality of support posts projecting at intervals along the longitudinal direction (left-right direction) of the solar cell array, and a vertical rail along the longitudinal tilt direction of the gantry frame for supporting the photovoltaic power generation panel is provided. A structure in which an upper end of each column is connected to an intermediate position and an inclined arm is connected between the body of each column and the front side or both front and rear sides of each vertical beam (Patent Document 1), solar power generation A structure in which a frame for supporting a panel 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 to the front-rear and the left-right (Patent Document 2) is representative.

Both are heavy, and because they are both heavy, they are likely to be misaligned when they are lifted sequentially by mechanical force and installed at predetermined intervals along the left-right direction, but the vertical and left-right directions via the mounting brackets 5A, 5B With this position adjustment, the position of the support portion on the gantry frame 1 side can be easily aligned without performing a position correction operation requiring labor of the concrete foundations 4A and 4B itself.

  According to the invention of claim 3, the mounting brackets 5A and 5B are fastened to the concrete foundations 4A and 4B with the nuts N through the anchor bolts 41 projecting from the top surfaces thereof through the long holes 51 of the horizontal plate portion 5a. Fixing and mounting, and fixing bolts through nuts N through the mounting holes B through the long holes 52 of the vertical wall portions 5b and 5c with respect to the support portion (the cross beam 12 and the support column 2) on the gantry frame 1 side Therefore, the position of the support portion can be adjusted in the vertical and horizontal directions with an extremely simple structure.

According to the invention of claim 4 , in the configuration in which the lower front side of the gantry frame 1 is directly fixed to the mounting bracket 5A as described above, the brace 3 is provided between the higher rear support columns 2 and 2. Therefore, the seismic strength and body wind pressure strength are further improved.

According to the invention of claim 5 , since the brace 3 is made of a square member having a reinforcing hollow portion 3a that is partitioned by a plurality of reinforcing pieces 3b, the brace 3 has high rigidity and extremely high strength, and can be bent in an attached state. It is hard to bend and exhibits a high reinforcing action as a brace, and even if both ends are firmly bolted to the support column 2, there is no fear that the bolted portion will be bent.

According to the invention of claim 6 , in the configuration in which the front side of the gantry frame 1 is directly fixed to the mounting bracket 5A as described above, and the brace 3 is provided between the support columns 2 and 2 on the rear side, the front side Because the concrete foundation 4A is set higher than the concrete foundation 4B on the rear side, even if the support position on the front side of the gantry frame 1 is set behind the frame front end, the lower frame front end is made high concrete. The foundation 4A can be reliably separated upward from the installation surface. On the other hand, even if the support position on the rear side of the gantry frame 1 is set to a position deeper forward than the rear edge of the frame, the support column 2 is lengthened by the low concrete foundation 4B, and the inclination angle of the brace 3 is increased accordingly. The reinforcing effect can be enhanced. And, since the distance between the front and rear support positions is shortened by supporting the front side and the rear side of the gantry frame 1 at a deeper position in this way, the gantry frame 1 is less likely to bend in the front and rear direction, and as a gantry structure The overall strength of the is improved.

According to the seventh aspect of the present invention, the gantry frame 1 has a left and right length of 3 spans or more with the span between the adjacent support columns 2 and 2 as one span, and each one or every two spans including the spans on both the left and right sides. Since a pair of braces 3 and 3 crossing each other in an X shape are provided on the span, even if the number of attached braces 3 is reduced and the member cost is reduced, it is possible to secure a large strength as a gantry structure. There is.

At the same time, the pillars 2 attached to the rear side rails 12 at predetermined intervals are supported and fixed to the concrete foundations 4B via the mounting brackets 5B. These support portions are vertically and horizontally moved by the mounting brackets 5A and 5B. Since the position can be adjusted, even if the solar cell array is enlarged as mega solar or giga solar, the height and position of a large number of the supporting portions can be easily and evenly arranged, and high construction accuracy can be obtained.

  That is, when the concrete foundations 4A and 4B are laid foundations, the top heights are likely to be uneven due to unevenness of the installation surface, and when the foundations are pile foundations due to variations in embedding depth. Therefore, when it is lifted by mechanical force sequentially and installed at predetermined intervals along the left and right direction, it is easy to cause a position shift, but the concrete foundation can be adjusted by adjusting the position in the vertical and left and right directions via the mounting brackets 5A and 5B. The position of the support portion on the gantry frame 1 side can be easily aligned without performing a position correction operation requiring labor of 4A and 4B itself. In addition, even if some concrete foundations 4A and 4B float due to uneven settlement of the ground after construction or surface erosion due to rainwater, the upper and lower positions of the supporting parts are readjusted so that the original load load is reduced. By returning to the applied state, damage to the photovoltaic power generation panel P due to stress concentration when subjected to earthquake motion or wind pressure can be avoided.

  As the photovoltaic power generation panel frame of the present invention, a column is also provided on the lower front side of the inclined frame 1 and the lower end of the column is supported and fixed to the concrete foundation 4A via the mounting bracket 5A in the same manner as the rear side. It is possible to adopt a configuration that However, as in the embodiment described above, the cross rail 12 is directly fixed to the mounting bracket 5A on the lower front side of the inclined gantry frame 1, and is fixed to the mounting bracket 5B via the support column 2 on the higher rear side. With this configuration, the front side is rigidly supported and fixed to the concrete foundation 4A, so that it can be prevented from collapsing even when subjected to large shaking or wind pressure due to an earthquake, and it is difficult to cause damage or distortion. By not using a support on the part side, the number of members is reduced, so that the assembly work is facilitated and the member cost is reduced.

  Further, in a configuration in which the lower front side of the gantry frame 1 is directly fixed to the mounting bracket 5A, the seismic strength and the body wind pressure strength are further improved by providing the brace 3 between the high rear side support columns 2 and 2. Furthermore, if the concrete foundation 4A on the front side is set higher than the concrete foundation 4B on the rear side as in the embodiment, the support position on the front side of the gantry frame 1 is set to a position recessed behind the front end of the frame. The low frame front end can be reliably separated from the installation surface by the high concrete foundation 4A, while the support position on the rear side of the gantry frame 1 is set to a position recessed forward from the frame rear edge. The support 4 is lengthened by the foundation 4B, and the inclination angle of the brace is increased accordingly, so that the reinforcing effect can be enhanced. Since the distance between the front and rear support positions is reduced by supporting the front and rear sides of the gantry frame 1 in such a deep position, the gantry frame 1 is less likely to bend in the front and rear direction. As a whole, the overall strength is improved.

  In the present invention, as mounting brackets interposed between the concrete foundations 4A and 4B and the support portions on the front side and the rear side of the gantry frame 1, there are various mechanisms and structures for adjusting the vertical and horizontal positions. Different ones can be adopted. However, in the mounting brackets 5A and 5B including the horizontal plate portion 5a having the left and right elongated holes 51 and the vertical wall portions 5b and 5c having the elongated holes 52 in the vertical direction as in the embodiment, the concrete foundation 4A is used. 4B, an anchor bolt 41 protruding from the top surface thereof is passed through the long hole 51 and fixed with a nut N, and the long hole 52 is fixed to the support portion (the cross beam 12, the column 2) on the gantry frame 1 side. By simply passing the mounting bolt B through and tightening and fixing with the nut N, the position of the support portion can be adjusted in the vertical and horizontal directions, so that it is easy to operate and high working efficiency is obtained. Since it is extremely simple in structure, there is an advantage that it can be manufactured at low cost. In the embodiment, the vertical wall portions 5b and 5c having the long holes 52 in the vertical direction form a parallel plate shape. However, the vertical wall portions can be provided in an upright rectangular tube shape, an angle shape, a channel shape, or the like. is there.

  The gantry frame 1 illustrated as an embodiment has a vertical beam 11 along the front-rear direction inclined to the upper side and a horizontal beam 12 on the lower side. In the present invention, the vertical relationship between the vertical beam 11 and the horizontal beam 12 is provided. May be reversed. For example, when each photovoltaic power generation panel P has a long shape in the tilted front-rear direction, the number of arrangements in the tilt direction is reduced, so the horizontal rails 12 having a larger number so that each panel P can be supported at a plurality of locations. As the upper side, if these horizontal rails 12 are received by the vertical rails 11 arranged at intervals corresponding to the concrete foundations 4A and 4B, and supported by the concrete foundations 4A and 4B on the front side and the rear side of each vertical rail 11 respectively. Good.

  On the other hand, the inclination angle of the gantry frame 1 is not limited to 10 ° exemplified in the above-described embodiment, and may be set as appropriate in consideration of the surrounding conditions of the installation place, the light receiving efficiency depending on the latitude, and the like. For example, FIG. 9A shows a photovoltaic power generation panel mount in which the inclination angle is set to 20 °, and FIG. 9B shows the inclination angle set to 30 °.
