The vertical beam holding bracket 52 has a vertical cross-sectional shape similar to that of the upper member 6A of the coupling metal 6, and holds the vertical beam 11 in a state where the vertical beam 11 is held by an upward U-shaped holding frame portion 52a. The nut N is screwed and fastened to the bolt B penetrated to the position, thereby being fixed to the vertical beam 11. And the bracket main body 51 and the vertical beam holding | maintenance metal fitting 52 are bolted and integrated with the flat plate part 51b and 52b which both joined. Further, as shown in FIG. 9, the bracket 5B for erection of the trunk frame 14 at the base portion of the vertical column 2 has the same form as the bracket body 51 of the bracket 5A, and the trunk frame 14 is inserted into the annular portion 51a. In this state, the nut N is screwed and tightened to the bolt B passed through the annular portion 51a and the vertical column 2 at the insertion position, thereby fixing the body frame 14 and contacting the side surface of the vertical column 2 A nut N is screwed and tightened to a bolt B penetrated by the flat plate portion 51b and is fixed to the vertical column 2.

  As shown in FIGS. 5 and 6, the mounting bracket 9 for attaching the solar cell array 10 to the vertical rail 11 of the gantry frame 1 includes a holding frame portion 91 having the same vertical cross-sectional shape as the upper member 6 </ b> A of the coupling bracket 6. The spacer 92 is disposed on the holding frame portion 91 and a U-shaped locking piece 93. In this mounting bracket 9, the vertical frame 11 of the gantry frame 1 is held from above by the holding frame portion 91 and bolted, and the spacer 92 is surrounded by the solar power generation panels P, P adjacent in the front-rear direction. Between the frames F and F, the front and rear edges of the solar cell array 10 are arranged between the peripheral frame and the outer abutment plate 94, and the protruding ends of the U-shaped locking piece 93 are the upper surfaces of the peripheral frames F and F. Alternatively, the nut N is screwed and fastened to the bolt B passing through the holding frame portion 91 and the vertical rail 11 and the U-shaped locking piece 93 from below by locking the peripheral frame and the upper surface of the plate. Each photovoltaic power generation panel P is fixed to the crosspiece 11.

  It should be noted that the fastening bracket 4, the bracket body 51 of the bracket 5 </ b> A and the vertical beam holding bracket 52, the bracket 5 </ b> B, the upper and lower members 6 </ b> A and 6 </ b> B of the coupling bracket 6, the connecting bracket 7, the upward holding frame portion 7 a, and the mounting bracket 9. Each of the holding frame portions 91 is made of a short cut material of an aluminum mold material. The aluminum mold material and the hollow aluminum mold material described above include those made of aluminum and aluminum alloys.

  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 including the frame 1, the vertical column 2, the brace 3, the body frame 14, and the reinforcement frame 16 is trussed. A structure is formed so that the strength becomes very high, and a large support strength and wind pressure strength can be secured even in a place that is easily exposed to strong winds, and there are less restrictions on the installation location. In addition, since the vertical beam 11 and the horizontal beam 12, the vertical column 2, the brace 3, the brace mounting frame 13, the body frame 14, and the reinforcing frame 16 of the gantry frame 1 are all lightweight hollow aluminum materials, The weight is reduced, and 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 addition, in the above-described embodiment, the support position by each brace 3 is on the center side in the rectangle with the positions of the four vertical struts 2 on the front, rear, left and right in the rectangular unit U as the apexes. Even if it becomes larger, it is possible to prevent the deformation of the gantry frame 1 at the center side, to avoid damage to the photovoltaic power generation panel P and a decrease in power generation efficiency due to the bending deformation, and to apply a load applied to each brace 3. Since it is received on the base side of the vertical support 2 and the load is less likely to act as a bending force on the vertical support 2, sufficient durability can be obtained even if the vertical support 2 is a thin hollow aluminum material.

  The brace mounting bar 13 assembled to the gantry frame 1 and the body frame 14 installed between the lower end portions of the vertical column 2 form a cylindrical shape, and are fitted and fixed to the brace mounting frame 13 and the body frame 14. Since the upper and lower end portions of each brace 3 are fixed to the brace mounting bar 13 and the trunk bar 14 via the fixing metal fitting 4 that is made, the inclination angle and the inclination direction of each brace 3 are different. It is possible to cope with the problem by adjusting the fitting position and the rotation posture with respect to the brace mounting bar 13 and the body bar 13 using the same fastening metal fitting 4, and a common member can be used for the difference in the overall size of the solar cell array 10. Thus, the material cost can be reduced accordingly, and each brace 3 can be fixed by the same operation procedure, so that the construction work is facilitated.

  In particular, in the fastening bracket 4 in the above-described embodiment, the pair of brace mounting pieces 4b and 4b extend outward from the annular portion 4a into which the brace mounting bar 13 or the trunk bar 14 is inserted, and both brace mounting pieces 4b and 4b. Since the upper and lower end portions of the brace 3 are sandwiched between them, the brace is fitted in advance to the brace mounting bar 13 and the body bar 14 at the time of installation work, and the brace according to the direction and position of the front end side of the brace 3 By adjusting the fitting position and the rotational posture with respect to the mounting bar 13 and the body bar 14, there is an advantage that the fastening operation of the brace 3 becomes extremely easy. Further, a brace mounting bar 13 is installed between adjacent vertical members 11 and 11 of the gantry frame 1 via a bracket 5A, and the bracket 5A is inserted between the annular part 51a into which the brace mounting bar 13 is inserted and the vertical frame of the gantry frame 1. Since the crosspiece mounting bracket 52 attached to the material 11 is provided, the brace mounting crosspiece 13 can be easily and securely attached firmly to the gantry frame 1.

  On the other hand, the vertical beam 11 and the horizontal beam 12 of the gantry frame 1 are coupled via the coupling bracket 6, and each vertical column 2 is coupled to the vertical beam 11 or the lateral beam 12 via the coupling bracket 7 at the upper end. Because of the fixed configuration, the gantry frame 1 that is inclined can be easily and securely attached to each vertical column 2 firmly. Further, the coupling metal 6 and the coupling metal 7 hold the vertical cylindrical beam 11 and / or the horizontal beam 12 of the gantry frame 1 by the holding frame portions 6a, 6b, 7a, and from the side at the holding position. Since the nut N is screwed and tightened to the bolt B that has been passed through, the attachment portions of the metal fittings 6 and 7 to the vertical beam 11 and / or the horizontal beam 12 become high in strength, and the installation work is easy and reliable. It can be done. In particular, in the configuration in which the steel reinforcing pipe 15 is inserted into the connecting position of the horizontal beam 12 and the vertical column 2 by the connecting metal fitting 7 as in the embodiment, and the bolt B is passed through the insertion portion, the frame 1 The fixing portion of the vertical column 2 with respect to is extremely high in strength, and the strength as a frame structure is improved accordingly.

  Further, as in the embodiment, the upper and lower portions of the rectangular columnar vertical beam 11 and the horizontal beam 12 of the gantry frame 1 form wide rectangular frame portions 11a and 12a, and the holding frame portions of the coupling metal 6 and the coupling metal 7 are formed. 6a, 6b, 7a is configured to hold the square frame portions 11a, 12a so as not to be vertically disengageable and slidable in the longitudinal direction, with respect to the vertical beam 11 and the horizontal beam 12 of the gantry frame 1 during installation work. There is an advantage that the work operation can be performed more easily by fitting both the metal fittings 6 and 7 in advance and moving them to the required position at the time of assembly.

  In addition, in the coupling bracket 6 and the coupling bracket 7 of the embodiment, when the coupling bracket 7 is attached to the rectangular cylindrical vertical beam 11 and the horizontal beam 12 of the gantry frame 1 using the bolt B and the nut N, the nut By screwing and tightening N, the pair of protruding strips 63, 63, 68, 68, 72, 72 on the inner surface facing the holding frame portions 6a, 6b, 7a are formed into the vertical beam 11 and the recessed portion 11b of the horizontal beam 12. , 12b, so that the tightening force by the nut N is distributed over a wide area, so that the vertical beam 11 and the horizontal beam 12 are not easily deformed due to local concentration of the tightening force, and the tightening is performed accordingly. There is an advantage that the force can be increased to form a strong bonded state. In the case of the present embodiment, the effect of suppressing distortion deformation due to such dispersion of the tightening force is due to the fixing portion of the bracket 5A to the vertical beam 11 by the vertical beam holding bracket 52 and the holding frame portion 91 of the mounting bracket 9. It can be obtained in the same manner in the fixed portion with respect to the vertical beam 11. In particular, in the configuration in which the reinforcing pipe 15 is inserted into the connecting position of the horizontal beam 12 and the vertical column 2 by the connecting bracket 7, each of the recessed portions 12b, 12b on the both sides of the horizontal beam 12 as shown in the embodiment. If a pair of ridges 12c, 12c along the longitudinal direction is provided and the tightening force by screwing and tightening the nut N is applied to the reinforcing pipe 15 via the ridges 12c, 12c, Strain deformation can be prevented more reliably.

  As the solar cell array 10 to which the present invention is applied, the configuration in which the four photovoltaic power generation panels P are arranged along the inclined front-rear direction in the above embodiment is exemplified. However, 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 the vertical support | pillars 2 along the front-back (inclination) direction in an installation apparatus will increase / decrease with the breadth of the whole width | variety of the front-back direction of the solar cell array 10. FIG. 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 16 and 16 are installed between the columns 2 and 2, 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 the two vertical columns 2; Furthermore, the brace 3 is installed between the middle part of the gantry frame 1 and the middle part of the vertical column 2 on the high rear side, thereby ensuring the overall strength of the gantry structure. Further, in the installation apparatus of FIG. 10 (b), in order to install the similar solar cell array 10A at a low level, one reinforcing bar 16 is installed between the root portions of the two front and rear vertical columns 2, 2, By bracing the braces 3 and 3 in an inverted V shape between the middle portion of the frame 1 and the base portions of the two vertical struts 2, the overall strength of the gantry structure can be ensured. However, as shown by the solid line and the virtual line in the figure, the opening angle of the inverted V shape of the braces 3 and 3 changes 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 supports 2 and 2 will be 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. Further, two upper and lower reinforcing bars 16, 16 are installed between the two front and rear vertical struts 2, 2, and the brace 3 is placed between the middle part of the base frame 1 and the base part of the two vertical struts 2 and the base frame 1. The overall strength of the gantry structure is ensured by erection between the middle part of the vertical column and the middle part of the vertical column 2 on the rear side. 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 root portions of the front and rear vertical columns 2, 2. One reinforcing bar 16 is installed, and braces 3 and 3 are installed in an inverted V shape between the middle part of the gantry frame 1 and the base parts of the two vertical columns 2, thereby ensuring the overall strength of the gantry structure. The opening angle of the inverted V-shaped braces 3 and 3 changes depending on the inclination angle of the solar cell array 10B, and the distance between the front and rear vertical columns 2 and 2 can be increased when the inclination angle is low. It is.

  In the installation apparatus of FIG. 12, in order to install a solar cell array 10C having a wide front-rear width in which four photovoltaic power generation panels P are arranged in an inclination direction, three vertical columns 2 of the front-rear part and the middle part are used. The braces 3, respectively, are arranged between the base of the vertical struts 2, 2 at the front and the middle and the gantry frame 1, and between the base of the vertical struts 2, 2 at the rear and the pedestal frame 1, respectively. 3 is installed in an inverted V-shape, and a reinforcing bar 16 is installed between the root portions over the three vertical columns 2 at the front and rear and the middle, thereby ensuring the overall strength of the gantry structure. 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 inclination angle is large, the positions of the middle and rear vertical struts 2, 2 with respect to the front vertical strut 2 are 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, each vertical support 2 is erected on the screw pile 8, but a concrete pile such as a PC pile may be used instead of the screw pile 8, and a non-pileable installation such as a flat roof is possible. At the place, the vertical support 2 may be erected on a concrete base.

  In the solar cell array installation apparatus according to the present invention, the number of braces 3 placed and the spacing between the four vertical struts 2 adjacent to the front and rear and right and left, and the inclination angle of each brace 3 are Not limited to the exemplary configuration according to the form, various settings can be made according to the size of the rectangular unit, the inclination angle of the gantry frame 1 and the like. As shown in FIG. 13, for example, as shown in FIG. 13, the upper end side of each brace 3 is fixed to a brace mounting bar (not shown) in the vicinity of the upper end of the vertical column 2 as the frame structure of the truss structure by the brace 3. At the same time, the lower end side is fixed on the base 17 at an intermediate position between the vertical struts 2 and 2 adjacent to each other by an appropriate attachment means, so that 2 A configuration in which the braces 3 and 3 of the book 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 brace 3 is not close to the center in the rectangle, so that the center side when the size of the rectangle is large It becomes easy to produce the bending deformation of the mount frame 1 at.

  Furthermore, in the present invention, the form of the fixing metal fittings 4, brackets 5A and 5B, coupling metal fittings 6 and connecting metal fittings 7 and their attachment structures, the attachment structure of the solar cell array 10 to the frame frame 1, the vertical beam of the frame frame 1 11 and various configurations other than the embodiment can be changed in detail, such as a cross-sectional shape of a hollow aluminum mold member used for the horizontal rail 12, the brace mounting rail 13, the trunk rail 14, the vertical column 2, and the brace 3.
