In addition, the solar cell array 10 can be attached to the gantry frame 1 by bolting one peripheral frame F to the vertical beam 11 of the gantry frame 1 even at positions adjacent to the front and rear photovoltaic panels P, P. It is fastened.

  At the connecting portion between the vertical beam 11 and the vertical columns 2A and 2B of the gantry frame 1, as shown on the rear side shown in FIG. 3, a downward-opening U-shaped frame-shaped connecting metal 5 connects the upper plate portion 5a to the vertical beam. In a state where it is joined to the lower surface of the belt 11, the nut N is screwed and fastened to the bolt B passing through the upper plate portion 5 a and the vertical beam 11, thereby being fixed to the vertical beam 11. The vertical strut 2B (2A) has an upper end 21 that is obliquely cut at an angle corresponding to the inclination of the gantry frame 1, and the connecting metal fitting 5 is straddled over the upper end so that both side pieces 5b, 5b of the connecting metal 5 And the vertical column 2B (2A) are connected to the vertical beam 11 of the gantry frame 1 by screwing and tightening a nut N to a bolt B penetrating from the side.

B is inserted into the vertical beam 11 and penetrated through the brace mounting beam 13, and a nut is screwed and tightened to the bolt B to fix both ends to the vertical beam 11. Further, the pivotal support metal 4A pivotally attaching the upper ends of the braces 3A and 3B to the left and right ends of the brace mounting bar 13 is composed of a pair of front and rear clamping plates 41 and 42 each made of a single metal plate. Yes. Both sandwiching plates 41, 42 are separated into left and right plate pieces 41a, 41b and plate pieces 42a, 42b by a central notch on the lower side, and the left side plate pieces 41a, 42a of both are forward and right side plate pieces. 41b and 42b are bent rearward at the same angle with respect to the upper part.

  Thus, the pivotal support 4A contacts the both sides of the brace mounting bar 13 with the upper side of both clamping plates 41, 42, and the nuts N are screwed into the bolts B penetrating from the side to the contact portions. The upper end portion of the brace 3A on the front side is sandwiched between the left side plate pieces 41a and 42a projecting in parallel obliquely forward of the both clamping plates 41 and 42 in a state where the brace mounting bar 13 is firmly fastened and obliquely The upper brace 3B on the rear side is sandwiched between the left side plate pieces 41a and 42a projecting in parallel to the rear, and nuts N are screwed onto the bolts B penetrating from the side at the respective clamping positions, whereby both braces The upper ends of 3A and 3B are pivotally attached to the brace mounting bar 13.

  On the other hand, the bracket 7A for pivotally attaching the lower end of each brace 3A, 3B to the vertical support 2A, 2B is made of a metal plate bent in a dogleg shape as represented by the rear side shown in FIG. 71 is fixed to the base side of the vertical support 2B (2A) with a bolt B and a nut N, and the lower end portion of the brace 3B (3A) is fixed to the pivot piece 72 projecting obliquely upward with a bolt B and a nut N. It is pivotally attached. Note that the vertical support 2B (2A) is erected on the base 17 by fitting the lower end side to the upper part of the anchor cylinder 17 with the lower part embedded in the base 17 and screwing it.

The upper ends of the short braces 6 are placed between the lower portions of the two metal plate members 74 and 75 hanging down while the upper portions of the two metal plate members 74 and 75 are in contact with both side surfaces of the horizontal rail 12 and fixed with bolts B and nuts N. The short brace 6 is pivotally attached by screwing a nut N to a bolt B that is sandwiched between the bolts and penetrated from the side. The bracket 7C for pivotally attaching the lower end of the short brace 6 to the rear vertical column 2B is made of an angle material, and one side piece 76 is fixed to the vertical column 2B with bolts B and nuts N. A lower end portion of the short brace 6 is pivotally attached to the other side piece 77 projecting sideward by a bolt B and a nut N.

  In the solar cell array installation apparatus having the above-described configuration, the gantry frame 1 that supports the solar cell array 10 is supported by four vertical columns 2 on the front, rear, left, and right for each rectangular unit U of the solar cell array 10. Since four braces 3 are inclined in the front-rear direction and the left-right direction for each unit U, the frame structure constructed from the frame 1, the vertical columns 2A, 2B and the braces 3A, 3B has a truss structure. When formed, the strength becomes very high, and a large support strength and wind pressure strength can be ensured even in a place that is easily exposed to strong winds, and there are fewer restrictions on the installation location. Further, since the vertical beam 11 and the horizontal beam 12, the brace mounting beam 13, the vertical columns 2A and 2B, and the braces 3A and 3B of the gantry frame 1 are all made of lightweight hollow aluminum material, the weight of the entire installation apparatus is reduced. At the same time, the workability during installation is improved. In addition, since the frame structure has high strength as described above, the material cost can be reduced by using a light and thin hollow aluminum material for the vertical support 2.

  In particular, in the above embodiment, the support position by each brace 3A, 3B is on the center side in the rectangle whose apexes are the positions of the four vertical struts 2A, 2A, 2B, 2B on the front, rear, left and right in the rectangular unit U. Even if the size of the rectangular unit U is increased, it is possible to prevent the deformation of the gantry frame 1 on the center side, and to avoid the damage to the photovoltaic power generation panel P and the decrease in power generation efficiency due to the bending deformation, Since the load of the load applied to the brace 3 is received at the base side of the vertical columns 2A and 2B and the load hardly acts as a bending force on the vertical columns 2A and 2B, the vertical columns 2A and 2B are thin hollow aluminum materials. However, sufficient durability can be obtained. Further, as in the embodiment, a reinforcing beam 14 is installed between the upper portions of the front and rear vertical columns 2A and 2B, or a short length is provided between the middle portion of the vertical column 2B on the rear side and the horizontal beam 12 of the gantry frame 1. By installing the brace 6 or by installing the reinforcing bar 15 between the base portions of the front, rear, left and right vertical columns 2A and 2B, the strength of the frame structure is further improved.

  On the other hand, since the brace mounting bar 13 has a rectangular tube shape, it can be firmly and easily attached to the rectangular tube-shaped vertical beam 11 or the horizontal beam 12 of the gantry frame 1 in a surface contact state. In addition, the upper ends of the braces 3A and 3B can be pivotally attached to the brace mounting bar 13 via the pivotal support 4A so that the angle of the braces 3A and 3B can be adjusted. obtain. Accordingly, when the inclination degree and installation height and size of the solar cell array 10 are different, the inclination angle and inclination direction of the braces 3A and 3B change, but a common member is used for each component including the pivotal support metal 4A. Thus, the material cost can be reduced, and the braces 3A and 3B can be pivotally attached in the same procedure, so that the construction work becomes easy. Further, the pivotal support 4A has an advantage that it can be very easily connected to both the brace mounting bar 13 and the braces 3A and 3B by bolting.

  Further, in the above embodiment, the upper end 21 of each vertical support 2A, 2B that is obliquely cut corresponding to the inclination of the gantry frame 1 is straddled with a downwardly-opening U-shaped frame-like connecting bracket 5 and bolted, Since the upper plate portion 5a of the coupling metal 5 is joined to the lower surface of the vertical beam 11 or the horizontal beam 12 of the gantry frame 1 and bolted, the vertical beam 11 or the horizontal beam 12 and the upper ends of the vertical columns 2A and 2B Can be firmly and easily connected in a surface contact state without backlash through the connecting metal fitting 5. Further, the brace mounting bar 13 can be firmly and easily attached to the vertical bar 11 by bolting in a state where the upper surface is joined to the lower surface of the vertical bar 11 of the gantry frame 1.

  In the above embodiment, the pivotal support 4A composed of the pair of front and rear clamping plates 41, 42 is exemplified. However, in the present invention, instead of the pivotal support 4A, for example, the pivotal support 4B shown in FIGS. Various types of pivot brackets such as ˜4E can be used. The pivot brackets 4B and 4C shown in FIG. 7 are pivotally attached to the front and rear braces 3A and 3B. The pivot bracket 4B in FIG. The front-side diagonally downward U-shaped fitting portion 44 with respect to the brace 3A of the portion is integrated, and the pivot metal fitting 4C of (b) is inclined backward and downward with respect to the same upward-shaped U-shaped fitting portion 43 and the rear brace 3B. The U-shaped fitting part 45 is integrated. Further, in the pivot metal fitting 4D shown in FIG. 8, the upward U-shaped fitting portion 43 with respect to the brace mounting bar 13 and the U-shaped fitting portions 44 and 45 with respect to the front and rear braces 3A and 3B are integrated. In these pivotal support brackets 4B to 4D, in each of the U-shaped fitting portions 43 to 45, the fitted brace mounting bar 13 and both the front and rear braces 3A and 3B are bolted as shown by the one-dot chain line in the drawing (the above-described embodiment). Bolts using bolts B and nuts N). 7 and 8, the bolting of the vertical beam 11 and the horizontal beam 12 of the gantry frame 1 is also indicated by a one-dot chain line.

And a nut N, a rectangular frame portion 47a of the pivot member 47 is pivotally attached. Between the leg plate portions 47b, 47b of the pivot member 47, the upper end of the brace 3A (3B) along the longitudinal direction, the bolt B and the nut N is pivotally attached. In this case, the pivot member 47 can swing in the front-rear direction with respect to the brace mounting bar 13, and the brace 3A (3B) can swing in the left-right direction with respect to the pivot member 47. The tilt direction and tilt angle of (3B) can be set freely.

  As the solar cell array 10 to which the present invention is applied, the configuration in which the three photovoltaic power generation panels P are arranged along the tilted front-rear direction is exemplified in the above embodiment, but the number of the power generation panels P arranged in the front-rear direction is exemplified. There is no particular restriction on the overall width. Therefore, the number of vertical support columns along the front-rear (inclination) direction in the installation device increases or decreases depending on the overall width of the solar cell array 10 in the front-rear direction. Moreover, about the length of the solar cell array 10 in the left-right direction, there are only restrictions due to the size of the site, the scale of the power generation system, and the layout. On the other hand, the inclination angle of the solar cell array 10 may be set to an angle at which the light receiving efficiency becomes the highest on an average annually according to the latitude of the installation location, and is arbitrarily set from 0 ° immediately below the equator to 90 ° in the polar region. it can. Incidentally, FIG. 10 to FIG. 12 show configuration examples of the installation device depending on differences in the overall width, inclination angle, and installation height of the solar cell array when the inclination width of the photovoltaic power generation panel P is about 1 m.

  First, in the installation apparatus of FIG. 10 (a), in order to install a solar cell array 10A having a narrow overall width in which two photovoltaic power generation panels P are arranged in an inclined direction at a high level, two vertical front and rear elevations are provided. Two upper and lower reinforcing bars 15 and 17 are installed between the columns 2A and 2B, and braces 3 and 3 are installed in an inverted V shape between the middle part of the gantry frame 1 and the bases of both vertical columns 2A and 2B. Furthermore, the brace 3C is installed between the middle part of the gantry frame 1 and the middle part of the vertical column 2B on the higher rear side, thereby ensuring the overall strength of the gantry structure. Further, in the installation apparatus of FIG. 10B, in order to install the similar solar cell array 10A at a low position, one reinforcing bar 15 is installed between the roots of the two front and rear vertical columns 2A and 2B, By bracing the braces 3A and 3B in an inverted V shape between the middle portion of the frame 1 and the base portions of both vertical supports 2A and 2B, the overall strength of the gantry structure can be ensured. However, as indicated by the solid and virtual lines in the figure, the opening angle of the inverted V-shape of the braces 3A and 3B varies depending on the inclination angle of the solar cell array 10B, and when the inclination angle is low and long in the front-rear direction, The distance between the vertical struts 2A and 2B is increased.

  In the installation apparatus of FIG. 11A, the solar cell array 10B having a slightly wider front and rear width in which the three photovoltaic power generation panels P are arranged in the inclination direction is installed at a high level, but is the same as in the case of the solar cell array 10A. In addition, two upper and lower reinforcing bars 15 and 17 are installed between the two front and rear vertical struts 2A and 2B, and the braces 3A and 3B are placed between the intermediate portion of the gantry frame 1 and the base portions of the two vertical struts 2A and 2B. Further, a brace 3C is installed between the intermediate portion of the gantry frame 1 and the intermediate portion of the vertical column 2B on the rear side, thereby ensuring the overall strength of the gantry structure. Further, in the installation apparatus of FIG. 11B, the similar solar cell array 10B is installed at a low position, but, similarly to the case of the solar cell array 10A, between the base portions of the front and rear vertical columns 2A and 2B. One reinforcing bar 15 is installed, and braces 3A and 3B are installed in an inverted V shape between the middle part of the frame 1 and the bases of the two vertical columns 2A and 2B, so that the overall strength of the frame structure is achieved. The opening angle of the inverted V-shape of the braces 3A and 3B changes depending on the inclination angle of the solar cell array 10B, and the distance between the front and rear vertical columns 2A and 2B can be increased when the inclination angle is low. Is the same.

  In the installation apparatus of FIG. 12, in order to install the solar cell array 10C having a wide front-rear width in which the four photovoltaic power generation panels P are arranged in the tilt direction, the vertical vertical part 2A, 2B in addition to the front and rear vertical columns 2A, 2B While using the support 2C, between the base of the vertical support 2A, 2C of the front part and the intermediate part and the frame 1 and between the base of the vertical support 2C, 2B of the rear part and the support frame 1 Each of the braces 3A and 3B is installed in an inverted V shape, and a reinforcing bar 15 is installed between the root portions of the three vertical columns 2A to 2C of the front and rear portions and the middle portion, thereby improving the overall strength of the frame structure. Secured. In this case, since the solar cell array 10C is large in size and the change in the length in the front-rear direction due to the difference in the inclination angle is large, the positions of the middle and rear vertical columns 2C, 2B with respect to A with respect to the front vertical column 2 However, the lower the angle of inclination, the more it moves backward.

  In the embodiment, since the solar power generation panel P of the solar cell array 1 is horizontally long, the solar cell array 1 is supported by the vertical rail 11 of the gantry frame 1, but the solar power generation panel P is vertically long. In this case, the solar cell array 1 is supported by the horizontal rail 12 of the gantry frame 1. In the embodiment, the brace mounting bar 13 is installed between the vertical bars 11 and 11 of the gantry frame 1 along the left-right direction. However, the brace mounting bar 13 extends between the horizontal bars 12 and 12 of the gantry frame 1 along the front-rear direction. You may build in the form. Further, in the embodiment, the vertical columns 2A and 2B are erected on the base 16, but a concrete pile such as a screw pile or a PC pile may be used when the installation place is a ground that can be piled.

  In the solar cell array installation apparatus according to the present invention, the number and interval of braces arranged in a rectangle whose apexes are four vertical struts adjacent to the front and rear and right and left, and the inclination angle of each brace are illustrated by the embodiments. Not limited to the configuration, various settings can be made according to the size of the rectangular unit, the inclination angle of the gantry frame, and the like. As shown in FIG. 13, for example, as shown in FIG. 13, the upper ends of the braces 3A and 3B are placed near the upper ends of the vertical support columns 2A to 2C as shown in FIG. ), And by pivotally attaching the lower end side thereof on the base or the like via an appropriate attachment means at an intermediate position between the vertical struts 2A, 2C and 2C, 2B adjacent to each other. A configuration in which two adjacent braces 3A and 3B are arranged so as to form a V-shape contrary to the above-described embodiment can also be adopted. However, in this case, although the strength as the gantry structure is increased by the truss structure, the support position of the gantry frame 1 by the braces 3A and 3B is not close to the center of the rectangle, so that the size of the rectangle is large. It becomes easy to produce the bending deformation of the mount frame 1 in the center side.

  Furthermore, in the present invention, the form of the connecting metal fitting 5 and the brackets 7A to 7C and their mounting structure, the mounting structure of the solar cell array 10 to the mounting frame 1, the vertical beam 11 and the horizontal beam 12 of the mounting frame 1, the brace mounting beam 13, various configurations can be changed in addition to the embodiment, such as the cross-sectional shape of the hollow aluminum mold material used for the reinforcing bars 14 and 15, the vertical supports 2A and 2B, the braces 3A and 3B, and the short braces 6.
