  Here, in this embodiment, the solar cell panel 2 includes a panel body 21 and a frame 22 that surrounds the outer periphery thereof. The frame 22 is positioned on the horizontal rail 220, and a through hole 22a used for bolting or the like is provided on the lower surface of the frame 22, for example. The through-hole 22a of this frame 22 is utilized for attachment of the solar cell panel 2 to the horizontal rail 220 in this embodiment.

  As shown in FIG. 14, the inner end metal fitting 23 attached to the inner surface of the horizontal beam 220 and the outer metal fitting 24 attached to the outer surface of the horizontal beam 220 are used to attach the solar cell panel 2 at the array end. It is done. Both the outer metal fitting 24 and the inner metal fitting 23 are sheet metal parts that are bent in a C shape so as to follow the cross-sectional shape of the horizontal rail 220. A locking claw 24 a that locks into a locking hole 221 a provided in the side wall 221 is formed at the lower end edge of the outer metal fitting 24 that overlaps the side wall 221 of the horizontal rail 220. Also, a similar locking claw 23 a is provided at the lower end edge of the inner metal fitting 23 that overlaps the side wall 221 of the horizontal rail 220.

The contact protrusion 23 b protrudes from the upper surface of the outer metal fitting 24 through a through hole (not shown) formed in the upper wall 224 and the outer metal fitting 24 of the horizontal rail 220.

  A pair of insertion protrusions 24b that are inserted into the through holes 22a of the frame 2 in the solar cell panel 2 are folded from the outer metal fitting 24 into a tongue-like shape. The solar cell panel 2 is placed on the outer surface metal fitting 24 so that the lower end corner is in contact with the contact protrusion 23 b and the insertion protrusion 24 b is inserted into the through hole 22 a of the frame 22.

  The end of the frame 22 of the solar battery panel 2 placed in such a manner is fixed to the crosspiece 220 by a screw 26 via an end pressing bracket 25 that is pressed from above. As shown in FIG. 14, the end pressing metal fitting 25 is a sheet metal working part formed in a shape bent in an inverted L shape in a side view. The end holding metal fitting 25 is arranged such that the long side portion 25a extends along the side surface of the solar cell panel 2 and the tip end portion of the short side portion 25b is hooked on the upper end corner. And the screw | thread 26 is attached through the through-hole provided in the short side part 25b.

  Here, similarly to the end presser fitting 25, the horizontal rail 220 and the outer metal fitting 24 are provided with through holes for allowing the screws 26 to pass therethrough. On the other hand, the inner metal fitting 23 is provided with a hole having a diameter smaller than the screw diameter at a position where the screw 26 passes. And the screw | thread 26 is screwed in so that this small diameter hole may be expanded while cutting a female screw in the inner periphery. The screw 26 is fixed by screwing with the female screw. By fixing the screws 26 in this way, the end portion of the frame 22 of the solar cell panel 2 is fixed to the horizontal beam 220 in a state where it is pressed toward the horizontal beam 220 by the end pressing metal fitting 25.

  As shown in FIG. 1, the fixing by the inner metal fitting 23, the outer metal fitting 24, and the end pressing metal fitting 25 is performed at two locations for each solar panel 2 in each of the horizontal rails 220 at both ends. 6 places, a total of 12 places.

  FIG. 15 is a diagram showing a state in which the solar cell panel is attached to three horizontal bars connected to the middle part of the vertical bars among the five horizontal bars shown in FIG. 1.

  The edges of the two solar cell panels 2 are positioned next to each other on the horizontal beam 220 connected to the intermediate portion of the vertical beam 210 via the horizontal beam support bracket 240 described above.

  Also in such a place, the through-hole 22a provided in the lower surface of the frame 22 surrounding the panel main body 21 is used for attaching the solar cell panel 2 to the horizontal rail 220.

  Also in this case, the inner surface metal fitting 23 and the outer surface metal fitting 24 also shown in FIG. Here, the two solar cell panels 2 are arranged on the outer surface so that the lower end corners of the two solar cell panels 2 are in contact with the contact protrusions 23b of the inner metal fitting 23 from the width direction of the horizontal rail 220. It is placed on the metal fitting 24. At this time, each of the pair of insertion protrusions 24 b of the outer metal fitting 24 is inserted into the through hole 22 a of the frame 22 of each solar cell panel 2.

  The ends of the frames 22 of the two solar battery panels 2 placed in such a manner are fixed to the horizontal rails 220 by screws 26 through boundary pressing metal fittings 27 that are pressed from above. The boundary presser metal fitting 27 is a sheet metal working part in which an entry protrusion 27a is raised from each of a pair of short sides of a rectangular plate as shown in FIG. The boundary pressing metal 27 is disposed such that a pair of entry protrusions 27a enter between two solar cell panels 2 adjacent to each other. And the screw | thread 26 is attached through the through-hole provided in the part of the rectangular board. As described above, the screw 26 is screwed so that a small-diameter hole provided in the inner surface metal fitting 23 is pushed and expanded while cutting a female screw on the inner periphery thereof. The screw 26 is fixed by screwing with the female screw. By fixing the screws 26 in this way, the end portions of the frames 22 of the two adjacent solar battery panels 2 are fixed to the horizontal beam 220 in a state where they are pressed toward the horizontal beam 220 by the boundary pressing metal fittings 27. Is done.

  As shown in FIG. 1, the fixing by the inner metal fitting 23, the outer metal fitting 24, and the boundary holding metal fitting 27 is performed on each of the three horizontal bars 220 in the middle portion with respect to one solar cell panel 2. It is performed at 6 places, 2 places each, for a total of 18 places.

  Furthermore, in the present embodiment, the following cover member 28 is disposed at the position of the boundary where the two solar cell panels 2 are adjacent in the X-axis direction in the horizontal rail 220.

  FIG. 16 is a diagram illustrating a cover member that is disposed at a position of a border where two solar battery panels are adjacent to each other in the horizontal rail.

  The cover member 28 is a band-shaped member that has been subjected to a corrosion-resistant surface treatment, and is disposed so as to be sandwiched between the horizontal rail 220 and the two solar cell panels 2. The cover member 28 is disposed so as to overlap the upper surface wall 224 of the horizontal rail 220 so as to intersect the horizontal rail 220. On this cover member 28, the two solar cell panels 2 will be mounted so that a boundary may overlap.

  The support frame 10 described above is assembled to the ground A11 by the following procedure.

  First, as shown in FIGS. 2 to 5, four base bodies 110 in the ground side support structure 100 are erected vertically on the ground A <b> 11 having unevenness. At this time, the base body 110 is erected at a sufficient burying depth in the main body 111, which is a screw pile, according to the condition of the rock in the ground A11.

  Subsequently, the support rod 120 is attached to each of the four bases 110 while adjusting the height of the upper end 121 from the ground A11 so that the solar cell panel 2 as the support object has a desired inclined arrangement. Further, a vertical rail support fitting 230 is attached to the upper end portion 121 of each support bar 120 while adjusting the height from the ground A11.

  Two vertical bars 210 are attached to the four vertical beam support brackets 230, and five horizontal bars 220 are attached to the vertical bars 210 via ten horizontal beam support metal parts 240. Then, the panel-side support structure 200 assembled in a lattice shape is assembled.

  At this stage, the vertical beam 210 is attached to the vertical beam support metal 230 and the horizontal beam 220 is attached to the horizontal beam support metal 240 in the following loose state. That is, the fastening of the vertical beam fixing screw 213 passing through the vertical beam long hole 212 and the horizontal beam fixing screw 223 passing through the horizontal beam long hole 222 is performed in a loose state with a certain degree of looseness.

  The following positioning operation using a positioning jig is performed on the panel-side support structure 200 assembled in such a loose state.

  FIG. 17 is a view showing a positioning jig used for the positioning operation with respect to the panel-side support structure shown in FIG.

  In this positioning operation, the vertical beam 210 and the horizontal beam are arranged so that the five horizontal beams 220 in the panel-side support structure 200 of the support frame 10 are arranged in parallel with each other at a distance d11 corresponding to the size of the solar cell panel 2. This is an operation for finely adjusting the position 220. As described above, in the stage up to this positioning operation, the vertical beam 210 is attached to the vertical beam support member 230 and the horizontal beam 220 is attached to the horizontal beam support member 240 in a loose state. The positioning operation is performed by slightly shifting the positions of the vertical beam 210 and the horizontal beam 220 in a relaxed state using the positioning jig 500 shown in FIG.

  The positioning jig 500 is formed by connecting two rail members 510 so as to be able to be opened and closed so as to intersect at the center of each other. A positioning pin 511 protrudes from the end of each rail member 510, and a similar positioning pin 512 protrudes from the central connecting portion. When the positioning jig 500 is opened, the relative positions of the five positioning pins 511 and 512 cause the three horizontal rails 220 to be parallel to each other at the interval d11 and perpendicular to the vertical rail 210. It will be a position to regulate so that they are lined up. Each horizontal bar 220 is provided with a through hole into which the positioning pins 511 and 512 of the positioning jig 500 are inserted.

  In the positioning operation, the positioning pins 511 and 512 of the opened positioning jig 500 are inserted into the positioning through holes in the horizontal rail 220. As a result of this insertion, the vertical beam 210 and the horizontal beam 220 are slightly displaced so as to regulate the position of the horizontal beam 200, and positioning is performed. In the present embodiment, the positioning operation is performed twice. The positioning operation is performed three by three using one positioning jig 500. Various screws for fixing the three cross rails 220 that are positioned are finally tightened and fixed. Then, various screws for fixing the vertical rail 210 to the ground side support structure 100 are finally tightened and fixed at the time of the second work after the positioning of all the horizontal rails 220 is completed.

  In the present embodiment, a mode in which the positioning operation is performed on the panel-side support structure 200 assembled in the above-described loose state is illustrated. However, the assembly before the positioning operation may be performed not in the loose state but in the following temporary assembly state, for example. In the temporarily assembled state, with respect to the vertical beam 210, a bar for temporary assembly, which replaces the vertical beam fixing screw 213, a positioning reference hole 216 and a vertical beam long hole 212 on the lower side in the inclined direction, and the vertical beam support bracket 230 are used. It is supposed to be inserted through a small-diameter hole before screw insertion. On the high-order side in the tilt direction, such a bar is not inserted, and the vertical beam 210 is only put on the vertical beam support fitting 230. On the other hand, all of the horizontal rails 220 are only put on the horizontal rail support fittings 240 on the vertical rail 210. By setting the panel-side support structure 200 in such a temporarily assembled state, it is possible to ensure a great degree of freedom in the positioning operation of the vertical beam 210 and the horizontal beam 220.

  Moreover, in this embodiment, the form which performs the positioning operation | work twice by changing the attachment position of one set of positioning jig | tool 500 is illustrated. However, the positioning operation is not limited to such an operation. For example, the positioning operation may be performed by using a plurality of sets (two sets in the present embodiment) of positioning jigs 500 at a time. In addition, the positioning jig 500 of the present embodiment regulates the positions of the three horizontal bars 200. However, the positioning operation may be an operation for positioning at a time using a set of positioning jigs that regulate the positions of all the horizontal rails 200 (5 in this embodiment).

  Further, in the positioning operation of the present embodiment, a mode in which the positions of the vertical beam 210 and the horizontal beam 220 are adjusted with respect to the panel side support structure 200 is illustrated. However, following this positioning operation, that is, after the construction is once completed, for example, the height of the support rod 120 or the vertical beam support fitting 230 in each ground side support structure 100 may be adjusted. . This height adjustment after construction will be described in detail later as a fifth modification.

  After such positioning work, the reinforcing rails 300 are attached to the support rods 120 of the two ground side support structures 100 located on the back side, which is the higher side of the inclined arrangement of the solar battery panel 2, and the two support members are supported. The bars 120 are connected. Twelve solar battery panels are attached to the support base 10 completed by the attachment of the reinforcing rail 300, and the photovoltaic power generation facility 1 shown in FIG. 1 is completed.

  Of the two support structures constituting the support base 10 in the embodiment described above, according to the ground side support structure 100, the height of the upper end 121 of the support bar 120 can be adjusted. Therefore, even if the ground A11 as the installation location is not flat and uneven, the height of the upper end 121 of the support bar 120 can be adjusted according to the height of each location. Thereby, the solar cell panel 2 which is a support target object can be supported to desired height via the panel side support structure 200 irrespective of the unevenness | corrugation of the earth A11. For this reason, the construction work etc. for making the earth A11 flat are unnecessary, and can be installed while suppressing burdens of labor and costs.

  Here, in the ground side support structure 100 of the present embodiment, the support rod 120 has a screw formed over the entire length including a partial range on the lower end portion 122 side. The base body 110 is provided with a nut 113 so that a partial range on the lower end portion 122 side of the support rod 120 that has passed through the opening 112a of the flange portion 112 is screwed. Thereby, by adjusting the screwing amount of the screw formed on the support rod 120 to the nut 113 in the base body 110, the height of the upper end portion 121 can be easily adjusted, thereby further reducing labor and cost burden. Can be installed.

  Further, in the ground-side support structure 100 of the present embodiment, the base body 110 is provided with a cylindrical main body portion 111 partially embedded in the ground A11, and an end portion of the main body portion 111 and an opening 112a. It is a hollow pile provided with a flange portion 112. Thereby, since the base | substrate 110 can be easily installed in the earth A11, it can install by further suppressing a burden of labor and cost.

  In addition, the base 110 is a hollow screw pile in which screw teeth are formed on the outer periphery of the main body 111. Since the screw pile can be easily installed with less noise and the like compared to a pile installed by driving, it can be installed with further reduced labor and cost.

  Moreover, according to the support base 10 of the present embodiment, the above-mentioned ground side support structure 100 is installed at all four places for supporting the solar cell panel 2 as a support object via the panel side support structure 200. Thereby, the solar cell panel 2 can be supported at a desired height via the panel-side support structure 200 regardless of the unevenness of the ground A11. For this reason, the construction work etc. for making the earth A11 flat are unnecessary, and can be installed while suppressing burdens of labor and costs.

  Moreover, according to the solar power generation facility 1 of this embodiment, since it has the structure which supports the solar cell panel 2 with the support stand 10 of this embodiment mentioned above, the construction work etc. for flattening the earth A11 etc. Is unnecessary and can be installed with reduced labor and cost.

  Moreover, according to the panel side support structure 200 among the two support structures constituting the support frame 10 in the present embodiment, the vertical beam oblong holes are formed in the three vertical beam connecting portions 200a except for one location serving as a positioning reference. 212 is provided. And the panel side support structure 200 is attached to the ground side support structure 100 which is a foundation structure with the freedom degree for the length of the vertical beam long hole 212 about each vertical beam connection location 200a. Further, the horizontal beam long holes 222 are provided in all of the horizontal beam connecting portions 200b. The panel side support structure 200 is attached to the vertical beam 210 with a degree of freedom corresponding to the length of each horizontal beam long hole 222. Thereby, when installing, even if the positioning accuracy of the position of the vertical beam 210 in the ground side support structure 100 or the position of the horizontal beam 220 in the vertical beam 210 is loosened to some extent, the vertical beam long hole 212 and the horizontal beam length A certain amount of misalignment can be absorbed by the holes 222. For this reason, according to the panel side support structure 200 of this embodiment, it can install, suppressing the burden of a labor and cost.

  Here, in the panel side support structure 200 of the present embodiment, a round hole for passing the vertical beam fixing screw 213 through one of the four vertical beam connection points 200a is provided as the positioning reference hole 216, and the other Longitudinal beam slots 212 are provided at all locations. In addition, a horizontal beam elongated hole 222 is provided in all of the 10 horizontal beam connection points 200b. As a result, most of the holes through which the vertical beam fixing screws 213 and the horizontal beam fixing screws 223 are made long are increased in the degree of freedom of attachment. Furthermore, by providing the positioning reference hole 216 in the vertical rail 210 on the side of the ground side support structure 100, the mounting position of the entire panel side support structure 200 with respect to the ground side support structure 100 can be determined.

  Further, in the panel side support structure 200 of the present embodiment, the reference beam member 210 a provided with the positioning reference hole 216 is formed in a different external shape from the other vertical beam 210. Thereby, since the operator can easily identify the reference crosspiece 210a at the time of installation, it can be installed with reduced labor and cost.

  Further, in the panel side support structure 200 of the present embodiment, the vertical beam elongated hole 212 is provided in the side wall 211 extending in the vertical direction in the vertical beam 210, and the horizontal beam elongated hole 222 is formed in the vertical direction in the horizontal beam 220. Is provided on the side wall 211 extending to the side. Further, the vertical beam 210 is covered with a vertical beam member 215 extending so as to intersect the upper surface wall 214 and the vertical beam slot 212, and the horizontal beam 220 is covered with the upper wall 224 and the horizontal beam of the horizontal beam 220. A horizontal belt-like member 225 that extends across the long hole 222 is covered. The vertical beam fixing screw 213 passes through the vertical beam long member 212 through the vertical beam member 215, and the horizontal beam fixing screw 223 passes through the horizontal beam member 225 through the horizontal beam long hole 222. Is done.

  Accordingly, for example, when a force is applied to lift the vertical beam 210 or the horizontal beam 220 upward during or after the installation of the panel-side support structure 200, the force is applied to the vertical beam strip member 215 or the horizontal beam. It is received by the belt-like member 225. As a result, it is possible to suppress the load that such force exerts on the peripheral portions of the vertical beam long hole 212 and the horizontal beam long hole 222.

  Moreover, in the panel side support structure 200 of this embodiment, the horizontal rail 220 is the 12 solar cell panels 2 arranged side by side as a support object. In the horizontal beam 220, the cover member 28 subjected to the corrosion-resistant surface treatment is disposed at a position that becomes the boundary of the solar cell panel 2 so as to be sandwiched between the horizontal beam 220 and the solar cell panel 2. ing. As a result, for example, rainwater or the like that has traveled down the boundary of the solar cell panel 2 to the horizontal beam 220 is received by the cover member 28 that has been subjected to a corrosion-resistant surface treatment, so that the life of the horizontal beam 220 after installation can be extended. it can.

  Moreover, in the panel side support structure 200 of this embodiment, the vertical beam support metal fitting 230 attached to the four vertical beam connection places 200a, and the horizontal beam support metal fittings 240 attached to the ten horizontal beam connection points 200b, It is equipped with. The vertical beam 210 is fixed to the vertical beam support bracket 230 by the vertical beam fixing screw 213, and the horizontal beam 220 is fixed to the horizontal beam support metal fitting 240 by the horizontal beam fixing screw 223.

  As a result, the connection between the vertical beam 210 and the ground support structure 100 and the connection between the horizontal beam 220 and the vertical beam 210 are performed via the vertical beam support fitting 230 and the horizontal beam support fitting 240. As a result, an operator can easily grasp the installation position of the vertical beam 210 in the ground side support structure 100 and the installation position of the horizontal beam 220 in the vertical beam 210 during installation. That is, according to the panel-side support structure 200 of the present embodiment, it can be installed with much less effort and cost.

  Further, in the panel side support structure 200 of the present embodiment, the vertical beam 210 has a concave shape in which the cross-sectional shape in the width direction accommodates the vertical beam support metal 230 inside, and is covered with the vertical beam support metal 230. It is fixed with. Further, the crosspiece 220 has a concave cross-sectional shape in which the horizontal crosspiece support fitting 240 is accommodated inside, and is fixed in a state of being covered with the horizontal crosspiece support fitting 240.

  Thereby, when attaching the vertical rail 210, the operator can temporarily place it in a stable state by placing it on the vertical rail support fitting 230, and then sequentially perform screwing operations. Similarly, when attaching the horizontal rail 220, the operator can temporarily place it in a stable state by placing it on the horizontal rail support bracket 240, and then sequentially perform screwing operations. Thus, according to the panel side support structure 200 of the present embodiment, it can be installed with further reduced labor and cost.

  Further, in the panel side support structure 200 of the present embodiment, the vertical beam support fitting 230 is provided with the vertical beam fulcrum protrusion 232 that supports the vertical beam 210 in a state where the inclination angle is adjustable. Further, the horizontal beam support fitting 240 is provided with a horizontal beam fulcrum projection 245 that supports the horizontal beam 220 in a state where the horizontal beam 220 is tilted so that the inclination angle can be adjusted.

  By supporting the vertical beam 210 and the horizontal beam 220 with the vertical beam fulcrum protrusion 232 and the horizontal beam fulcrum protrusion 245, the vertical beam 210 and the horizontal beam 220 can be easily installed at an inclination. Can be easily tilted.

  Moreover, according to the solar power generation facility 1 of this embodiment, since the above-described support frame 10 of this embodiment is used to support the solar cell panel 2, it can be installed with reduced labor and cost. .

  Next, modifications to the embodiment described above will be described.

  First, the first modification will be described. In the first modified example, the mounting structure of the support bar in the ground side support structure is different from the above-described embodiment. Hereinafter, the first modification will be described by paying attention to this difference.

  FIG. 18 is a view showing a mounting structure of a support bar in the ground side support structure of the first modification. In FIG. 18, components equivalent to those of the ground side support structure 100 shown in FIG. 8 are denoted by the same reference numerals as those in FIG. 8. The duplicate description of is omitted.

  The ground side support structure 600 of the first modification includes a base 610, a support bar mounting portion 620, and a support bar 120 similar to that of the above-described embodiment. The base body 610 is a screw pile similar to the base body 110 in the above-described embodiment except that a nut is not welded to the flange portion 612. Then, a C-shaped support rod mounting portion 620 is fixed to the flange portion 612 of the base 610 so as to cover the center opening 612a in a side view shown in FIG. The support bar mounting portion 620 includes a pair of opposing side walls 621, an upper surface wall 622, and a flange edge 623 that extends from the lower end of each side wall 621 and overlaps the flange portion 612. A through hole 622a through which the support bar 120 passes is provided at the center of the upper surface wall 622, and the support bar mounting portion 620 has a flange portion so that the through hole 622a overlaps the opening 612a of the flange portion 612 in a top view. 612 is fixed.

Two nuts 624 are screwed onto the support bar 120, and a flat washer 625 and an upper surface wall 622 of the support bar mounting portion 620 are disposed thereon. Then, the nut 125 is fastened to the support rod 120 that has passed through the through hole 622 a of the upper surface wall 622 via the flat washer 123 and the spring washer 124. The support bar 120 is fixed to the upper surface wall 622 of the support bar mounting portion 620 by two lower nuts 624 and an upper nut 125. At this time, the lower end portion 122 of the support rod 120 enters the inner space 610a of the base 610 through the opening 612a of the flange portion 612a.

  At this time, the position of the upper end 121 of the support bar 120 in the height direction D11 from the ground A11 is determined by the position of the nut 624 inside the support bar mounting part 620. For this reason, the height of the upper end 121 of the support bar 120 can be adjusted by adjusting the screwing position of the nut 624 and the support bar 120 in the height direction D11.

  The vertical beam 210 is attached to the ground side support structure 600 of the first modified example via the vertical beam support fitting 230 similar to the above-described embodiment.

  It goes without saying that the ground side support structure 600 of the first modified example described above can be installed with reduced labor and cost, similarly to the ground side support structure 100 of the above-described embodiment.

  Next, a second modification will be described. In this second modification, the ground side support structure 100 of the above-described embodiment and the ground side support structure of another structure shown below are used in combination as four bases for supporting the panel side support structure 200 in the support frame. ing. Hereinafter, the second modification will be described by paying attention to this difference.

  FIG. 19 is a diagram illustrating a ground-side support structure of another structure included in the support frame of the second modified example.

  Unlike the above-described embodiment, the ground-side support structure 700 having a different structure in the second modification example includes only a base body without a support bar. The ground-side support structure 700 of this different structure is attached to the flange portion 712 on the main body portion 111 similar to the base body 110 in the above-described embodiment. However, in the ground side support structure 700 having another structure, the flange portion 712 is not provided with an opening.

In the third modification, a member for positioning with respect to the support base 10 assembled in a loose state is different from that in the first embodiment described above. Hereinafter, a third modification will be described by paying attention to this difference.

  FIG. 21 is a diagram illustrating members for performing positioning in the support frame of the third modified example. In FIG. 21, the same components as those shown in FIG. 17 are denoted by the same reference numerals as those in FIG. 17, and the description of these equivalent components will be omitted below.

  In the embodiment described above, the positioning jig 500 shown in FIG. 17 is used for positioning in the support frame 10. The positioning jig 500 is removed after the positioning operation. On the other hand, in the third modified example, the following regulating member 800 that remains as a reinforcing member after the positioning operation is used.

  The regulating member 800 is screwed and fixed to each of the horizontal bars 220 while extending so as to be orthogonal to the five horizontal bars 220. The regulating member 800 is fixed in this manner, so that the five horizontal bars 220 are arranged in parallel with each other at intervals d11 according to the size of the solar cell panel 2 and perpendicular to the vertical bars 210. The position of the crosspiece 220 is regulated.

  When the regulating member 800 is fixed, the vertical beam 210 and the horizontal beam 220 are connected in a loose state. When the positioning is performed by fixing the regulating member 800, various screws for fixing the vertical beam 210 and the horizontal beam 220 are finally tightened and fixed. After that, the regulating member 800 remains in the panel side support structure 200 of the support frame 10 as a reinforcing member.

  According to the third modified example described above, the relative positioning of the five horizontal rails 220 can be performed by attaching the regulating members 800 to the five horizontal rails 220 at the time of installation. The solar panel 2 can be easily attached to the horizontal rail 220.

In the fourth modified example, a member for positioning with respect to the support frame 10 assembled in a loose state is different from the first embodiment described above. The fourth modification is a modification to the restriction member 800 of the third modification described above. Hereinafter, a fourth modification will be described focusing on this difference.

  FIG. 22 is a diagram illustrating members for performing positioning in the support frame of the fourth modified example. In FIG. 22, the same components as those shown in FIG. 17 are denoted by the same reference numerals as those in FIG. 17, and redundant description of these equivalent components will be omitted below.

  In the fourth modified example, as in the third modified example described above, the following regulating member 900 that remains in the panel side support structure 200 of the support base 10 as a reinforcing member after the positioning operation is used.

  The regulating member 900 in the fourth modified example has a horizontal beam as shown in FIG. 22, whereas the regulating member 800 in the third modified example shown in FIG. 220 is fixed obliquely crossing 220. The regulating member 900 fixed in this way also has the horizontal rails 220 such that the five horizontal rails 220 are arranged in parallel with each other at an interval d11 according to the size of the solar cell panel 2 and perpendicular to the vertical rails 210.

  Also in the fourth modified example described above, the relative positioning of the five horizontal bars 220 can be performed by attaching the regulating members 900 to the five horizontal bars 220 at the time of installation. The solar cell panel 2 can be easily attached to the horizontal rail 220. In addition, since the regulating member 900 remains as a reinforcing member even after positioning, the strength of the panel-side support structure 200 can be improved.

  Next, a fifth modification will be described. The fifth modified example is different from the first embodiment described above in that the height adjustment is performed after the construction in which the position adjustment of the vertical beam 210 and the horizontal beam 220 is completed with respect to the panel side support structure 200. Hereinafter, a fifth modification will be described by paying attention to the height adjustment after construction, which is the difference.

  FIG. 23 is a diagram illustrating a ground-side support structure in the support frame of the fifth modified example. In FIG. 23, components equivalent to those in the embodiment shown in FIG. 1 to FIG. 17 are denoted by the same reference numerals as those in FIG. 1 to FIG. Duplicate explanation for components is omitted.

  In the support frame 1000 of the fifth modified example, first, the peripheral shape of the nut 125 inside the vertical beam support fitting 1230 is simplified, and a mounting space for a nut fixing jig 1001 described later is secured. Further, in the ground side support structure 1100, the lower part of the vertical beam support fitting 1230 is supported by a double nut including two nuts 1101. The support bar 120 is fixed to the base 110 by an internal nut 113 and a split nut 1102 attached above the base nut 113.

  FIG. 24 is a diagram showing first and second steps of height adjustment after construction in the support frame of the fifth modified example shown in FIG. 23, and FIG. 25 is a diagram showing the first step shown in FIG. It is a figure which shows the 3rd and 4th step of the height adjustment after construction in the support stand of 5 modifications. 24 and 25, the same components as those in the embodiment shown in FIGS. 1 to 17 are denoted by the same reference numerals as those in FIGS. Then, the overlapping description with respect to these equivalent components is omitted.

  First, in this embodiment, the split nut 1102 shown in FIG. 23 is not yet attached at the start of the height adjustment after construction shown in FIGS. 24 and 25.

  In the first step S1001 of height adjustment after construction, a nut fixing jig 1001 is attached to the inside of the vertical beam support fitting 1230, and the nut 125 is fixed in a non-rotatable manner. The nut fixing jig 1001 has a plate-like jig formed in a substantially C shape in plan view, having two arms inserted between the side surface of the nut 125 and the inner wall surface of the vertical beam support fitting 1230. Then, it is inserted so as to surround the nut 125 from the open side surface of the vertical beam support fitting 1230. By inserting the nut fixing jig 1001, the nut 125 is fixed to be non-rotatable around the support bar 120 inside the vertical beam support fitting 1230.

  In the subsequent second step S1002, the support rod 120 is rotated by scratching and turning the spanner using the double nut consisting of the two nuts 1101 as a clue in the second step S1002. As a result, the upper structure including the support rod 120, the two nuts 1101, and the vertical beam support fitting 1230 is lowered in the direction of arrow D <b> 12. At this time, the nut 125 inside the vertical beam support bracket 1230 is fixed by the nut fixing jig 1001 so as not to rotate, so that the support bar 120 is lowered while the position of the nut 125 remains unchanged. As a result, the fastening of the nut 125 to the support bar 120 is loosened. By loosening the fastening of the nut 125, the support rod 120 and the upper structure using the double nut as a clue can be moved up and down.

  In the third step S1003, the nut fixing jig 1001 is removed, the spanner is scratched by a double nut composed of two nuts 1101, and the support rod 120 is rotated. At this time, the nut 125 inside the vertical beam support fitting 1230 rotates together with the support bar 120. The rotation of the support bar 120 adjusts the screwing amount of the support bar 120 to the nut 113 of the base 110 in the ground side support structure 1100, and as a result, the height of the support bar 120 and the upper structure is adjusted. In the example of FIG. 25, the height of the support bar 120 and the upper structure is raised as indicated by the arrow D13. In the third step S1003, the heights of the support rod 120 and the upper structure are adjusted to a desired height.

  When the adjustment in the third step S1003 is completed, the nut 125 is again non-rotatably fixed by the nut fixing jig 1001 in the subsequent fourth step S1004. Thereafter, the support bar 120 is rotated, and the two nuts 1101 are raised in the direction of the arrow D14 together with the support bar 120 while the fixed nut 125 is left as it is. Thereby, the nut 125 inside the vertical beam support fitting 1230 which has been loosened in the first step S1001 is fastened again. After this fastening, the nut fixing jig 1001 is removed. Finally, the split nut 1002 is attached to the base 110 side of the support rod 120.

  The split nut 1002 is formed in a shape that is split open so that it can be attached to a fitting object (here, the support rod 120). At the time of attachment, first, a split nut 1002 having an open shape is screwed into a screw of the support bar 120 while being closed using a pliers so as to surround the support bar 120 as a fitting object. Thereafter, the closed split nut 1002 is tightened with a spanner.

  With the fastening of the nut 125 inside the vertical beam support fitting 1230 and the fastening of the split nut 1002 in the fourth step S1004, the post-construction height adjustment in the support frame of the fifth modification is completed. In the fifth modification, such height adjustment is performed on a desired one of the four ground side support structures 1100.

  Here, the timing at which the height adjustment after construction is performed is after the position adjustment of the vertical beam 210 or the horizontal beam 220 with respect to the panel-side support structure 200 is completed, but is not limited thereto. This height adjustment may be performed after the solar cell panel 2 is mounted on the panel-side support structure 200. At this time, when the height adjustment is performed once before the solar cell panel 2 is mounted, the already installed split nut 1002 is loosened and the height adjustment is performed.

  According to the fifth modification described above, the height of the support bar 120 and the superstructure after the construction can be adjusted, so that the support frame 1000 can be installed while further reducing labor and cost burden. Can do.
