And a back surface support structure 112 that supports the back surface, which is a surface. A total of eight support legs 111 extend from the vicinity of the squares of the two solar battery panels 120 to the ground G11.

  A plurality of cloth foundations 130 are installed in parallel to each other on the ground G11 of the installation place A11. The fabric foundations 130 are provided in pairs with respect to one existing solar cell panel support structure 100 with an interval corresponding to the interval between the support legs 111 in the tilt direction. Anchor bolts 131 are provided on the upper surface of the fabric foundation 130 at positions adjacent to the lower ends of the support legs 111. The lower end of each support leg 111 is fixed to each anchor bolt 131 via a base L-shaped metal fitting 132. In this embodiment, each support leg 111 is provided so that the anchor bolt 131 is positioned on the left side in FIG. 2 with respect to the respective lower ends. A bracket 132 is arranged and fixed. In this way, the existing frame 110 is fixedly installed on the plurality of fabric foundations 130.

  In addition, a pair of fabric foundations 130 corresponding to one existing solar cell panel support structure 100 and a pair of fabric foundations 130 corresponding to another existing solar cell panel support structure 100 located next to each other in the inclination direction are: The following intervals are provided. That is, there is a sufficient distance that the shadow of the existing solar cell panel support structure 100 located on the front side in the tilt direction does not fall on the light receiving surface of the existing solar cell panel support structure 100 located on the rear side in the tilt direction. A fabric foundation 130 is provided that is opened.

  Here, in order to increase the power generation capacity of the power generation facility 10, when a new solar cell panel support structure is added, if there is a sufficient margin in the space of the installation location A <b> 11, The cloth foundations 130 are installed at the same intervals. On the other hand, when there is not enough room for the free space, the mutual spacing of the existing solar cell panel support structure 100 is packed in the moving direction D11 in FIG.

However, even if a decrease in power generation due to the shadow is taken into account, a new solar cell panel support A significant increase in power generation can be expected due to the expansion of the structure.

  The solar cell panel construction method of the present embodiment is a construction method in which the existing solar cell panel support structure 100 is moved in the moving direction D11 in FIG. is there.

  In this construction method, first, a rail installation process described below is performed.

  The rail installation process is performed from the vicinity of the existing frame 110 in the existing solar cell panel support structure 100 on the right side in FIG. 1 and the left side in FIG. This is a process of installing an extended rail 140.

  In this embodiment, C steel is used as the rail 140. The rail 140 is installed such that the band plate portion 140a corresponding to one of the pair of upper and lower arms in the C-shape of the cross section is on the upper side. In addition, a pair of rails 140 is installed so as to be parallel to each other with the support legs 111 positioned at the left and right ends in FIG. 2 among the eight support legs 111 of the existing mount 110. As shown in FIG. 1B, each rail 140 is installed so as to cross over a plurality of fabric foundations 130.

  Here, of the pair of rails 140, the left rail 140 in FIG. 2 is arranged adjacent to the left side of the left supporting leg 111 in FIG. 2, and the right rail 140 in FIG. It is arranged adjacent to the right side of the support leg 111. At this time, the rail 140 adjacent to the left side of the left support leg 111 in FIG. 2 will interfere with the anchor bolt 131 and the base L-shaped metal fitting 132 fixing the lower end of the support leg 111. . Therefore, for the existing solar cell panel support structure 100 to be moved, the foundation L-shaped metal fitting 132 that interferes with the rail 140 is removed and the anchor bolt 131 protrudes from the cloth foundation 130 in the rail installation process. The part where it is cut.

  Further, the rail 140 extends to the vicinity of the existing base 110 of the existing solar panel support structure 100 on the left side in FIG. 1 that is not the object to be moved, that is, to the upper side of the cloth base 130 for installing the existing base 110. Installed. As for the existing solar cell panel support structure 100 on the left side in FIG. 1 to be non-moved, it is necessary to maintain the fixed state. Instead, the rail 140 is partially cut to avoid interference.

  The pair of rails 140 installed over the fabric foundation 130 as described above are fixed to the respective fabric foundations 130 using the following chemical anchors, although illustration is omitted. First, a hole is formed so as to communicate with the fabric foundation 130 from the lower strip 140 b of the rail 140 on the fabric foundation 130. The hole of the fabric foundation 130 is filled with an adhesive, and an anchor bolt that penetrates the lower strip 140b of the rail 140 is inserted and fixed. A nut is fastened to the upper part of the anchor bolt to fix the rail 140. Such fixing is performed on each fabric base 130 and the rail 140 is fixed.

  Next, an attaching process of a holding device, which will be described later, and a moving and fixing process of the existing mount 110 are performed on the existing solar cell panel support structure 100 to be moved.

  FIG. 3: is a side view which shows the attachment process of the holding | maintenance apparatus in the solar cell panel construction method concerning 1st Embodiment, and the movement fixed process of an existing mount frame. FIG. 3A shows a side view of the existing solar cell panel support structure 100 to which the holding device 150 is attached and ready for movement. FIG. 3B shows a side view of the existing solar cell panel support structure 100 fixed to the rail 140 after movement. FIG. 4 is a view showing the attaching step of the holding device and the moving and fixing step of the existing gantry as seen in the direction of arrow V11 in FIG. FIG. 4A shows the V11 arrow view in FIG. 3A, and FIG. 4B shows the V11 arrow view in FIG. 3B.

  In the attachment process, the existing gantry 110 is detached from the cloth foundation 130. First, the holding device 150 is attached prior to the removal. The holding device 150 is a device that holds the existing frame 110 after being detached from the fabric foundation 130 so as to be movable up and down along the rail 140. One holding device 150 is attached to each of the four support legs 111 located on the left and right in FIG. 3A and on the left and right in FIG. 4A.

  FIG. 5 is an enlarged view of the holding device shown in FIGS. 3 and 4. 5 (a) shows an enlarged view of the holding device 150 in FIG. 3 (a), and FIG. 5 (b) shows an enlarged view of the holding device 150 in FIG. 3 (b). Yes.

  The holding device 150 includes a jack frame 151 and wheels 152 (rotating bodies). The jack frame 151 includes a jack L-shaped metal fitting 151 a that is bolted to the support leg 111, and a jack portion 151 b that raises and lowers the jack L-shaped metal fitting 151 a by a handle operation. The jack portion 151b includes a lever 151b-1 that is operated by an operator, and a main body portion 151b-2. The tip of the elevating protrusion 151b-2a of the main body portion 151b-2 is the L-shaped metal fitting 151a for the jack. It is fixed to the lower surface. In response to an operation on the lever 151b-1, the jack L-shaped metal fitting 151a moves up and down together with the lifting protrusions 151b-2a.

  Further, a pair of wheel holding frames 151b-3 are provided so as to protrude from the jack portion 151b toward the rail 140 with the main body portion 151b-2 interposed therebetween. A wheel 152 is rotatably attached to each wheel holding frame 151b-3. Each wheel 152 is provided with a flange portion 152 a that is engaged with the edge of the rail 140.

  The holding device 150 is attached to the support leg 111 by fixing the jack L-shaped metal fitting 151a to the support leg 111 with a bolt. At this time, as shown in FIG. 5B, the holding device 150 is attached so that the flange portion 152 a of each wheel 152 is locked to the edge of the rail 140.

  At this time, as shown in FIG. 5, the L-shaped metal fitting 160 for rails is bolted to the support leg 111 so that the lower wall 161 passes between the pair of wheels 152. At this stage of attachment, unlike in FIG. 5, the rail L-shaped metal fitting 160 is such that the lower surface of the lower wall 161 is in contact with the upper surface of the strip 140 a on the upper side of the rail 140.

  Further, in the attaching step, as shown in FIG. 4, the cross beam portion 171 is attached to the existing mount 110. The cross beam portion 171 includes four support legs 111 on the front side in the movement direction D11 (that is, on the lower side in the inclination direction), four support legs 111 on the rear side in the movement direction D11 (that is, on the upper side in the inclination direction), Two are arranged so as to cross each of the above. Each lateral beam portion 171 is bolted to each support leg 111.

  Then, in the attaching process, following the fixing of the holding device 150 and the cross beam portion 171 to the support legs 111, the foundation L-shaped metal fitting 132 is removed from all the support legs 111 of the existing mount 110, and the anchor bolts 131 are fixed. The protrusion is cut.

  When the attachment process is completed, a moving and fixing process is performed in which the existing solar cell panel support structure 100 is moved and fixed to the rail 140 at the destination.

  In the moving and fixing step, first, the existing frame 110 removed from the fabric foundation 130 is lifted together with the solar cell panel 120 via the four holding devices 150. This lifting is performed by raising the jack L-shaped metal fitting 151a together with the lifting projection 151b-2a as shown in FIG. 5 by operating the lever 151b-1 of the jack portion 151b in each holding device 150. As a result, the support leg 111 to which the jack L-shaped metal fitting 151 a is fixed, that is, the existing mount 110 rises with respect to the fabric foundation 130 and the rail 140. By this rise, a gap is opened between the lower end of the support leg 111 and the upper surface of the fabric foundation 130 as shown in FIG. Further, a gap is also opened between the lower surface of the lower wall 161 of the L-shaped metal fitting 160 for rail and the upper surface of the strip 140 a on the upper side of the rail 140.

  In this state, the intermediate support leg 111 positioned between the support legs 111 to which the holding device 150 is attached floats in the air as shown in FIG. 111 is supported by the cross beam portion 171.

  When preparation for movement is completed in this way, the existing frame 110 is moved in the movement direction D11 along the rail 140 to an arbitrary movement destination together with the supported solar cell panel 120.

  At the destination, the existing mount 110 is lowered by operating the lever 151b-1 of the jack portion 151b. The existing mount 110 is lowered until the lower surface of the lower wall 161 of the L-shaped bracket for rail 160 comes into contact with the upper surface of the strip 140a on the upper side of the rail 140. When the descent of the existing mount 110 is completed, the holding device 150 is removed from each support leg 111. Thereafter, the lower wall 161 of the rail L-shaped metal fitting 160 of each support leg 111 is bolted and fixed to the upper band plate portion 140a of the rail 140, which is shown in FIGS. 3 (b) and 4 (b). As shown, the existing frame 110 is fixed to the rail 140.

  FIG. 6 is an enlarged view of a fixing portion between the existing frame and the rail. 6 (a) shows an enlarged view corresponding to FIG. 3 (b), and FIG. 6 (b) shows an enlarged view corresponding to FIG. 4 (b).

  As shown in FIG. 6, the movement destination of the existing gantry 110 to be moved is a position that is out of the fabric foundation 130. In this movement destination, a hole for communicating the lower wall 161 of the rail L-shaped metal fitting 160 of each support leg 111 and the upper band plate portion 140a of the rail 140 is processed. Then, the bolt 162 is passed through the hole, and the nut 163 is fastened. The existing frame 110 is fixed to the rail 140 by this bolting and fixing. At this time, the intermediate support leg 111 that is not fixed to the rail 140 is supported by the cross beam portion 171 even in this fixed state. The movement and fixing step is completed by fixing the lower wall 161 of the rail L-shaped metal fitting 160 of each support leg 111 and the strip 140a on the upper side of the rail 140. With this, the solar cell panel construction method of the present embodiment is completed. Complete.

  In addition, about the support of the intermediate support leg 111 which is not fixed to the rail 140, it is not restricted to the support by the cross beam part 171 like this embodiment. For example, a method of arranging and supporting a spacer between the lower end of the intermediate support leg 111 and the ground G11 may be used, and the specific support method is not questioned. Or you may fix all the support legs to a rail like 3rd and 4th embodiment mentioned later.

  According to the solar cell panel construction method of the first embodiment described above, the existing solar cell panel support structure 100 can be moved, so that the space available for expansion in the original installation location. Can be created. For this reason, the construction cost can be reduced as compared with securing all the additional space outside the original installation location. And in the solar cell panel construction method of this embodiment, the movement of such an existing solar cell panel support structure 100 moves the existing gantry 110 along the rail 140 together with the solar cell panel 120 to move the rail 140 at the destination. It is done by fixing to. Thereby, for example, the existing solar cell panel support structure 100 can be moved at a low cost compared to a method of disassembling the existing solar cell panel support structure 100 and reconstructing it at the destination. Therefore, according to the solar cell panel construction method of the present embodiment, an additional space can be secured while suppressing construction costs.

  Moreover, according to the solar cell panel construction method of the present embodiment, the existing platform 110 (that is, the existing solar cell panel support structure 100) is moved up and down via the holding device 150 including the jack frame 151 and the wheels 152. Can be performed under good workability.

  In the solar cell panel construction method of the present embodiment, relatively inexpensive C steel is used as the rail 140. Thereby, the construction cost is further reduced.

  Moreover, in the solar cell panel construction method of the present embodiment, the holding device 150 is removed from the existing mount 110 at the destination. As a result, for example, the holding device 150 used for the movement of a certain solar cell panel support structure 100 can be reused for the movement of another solar cell panel support structure 100, so that the construction cost can be further reduced. .

  Moreover, in the solar cell panel construction method of this embodiment, a metal rail called C steel is used as the rail 140, and the rail 140 is in a non-contact state with respect to the ground G11 by being laid over the upper surfaces of the plurality of fabric foundations 130. Installed. Thus, by using a metal rail to improve the strength and installing in a non-contact state with respect to the ground G11, corrosion due to direct contact with the ground G11 can be avoided.

  Moreover, in the solar cell panel construction method of the present embodiment, a pair of rails 140 is installed so as to be parallel with a pair of support legs 111 at both left and right ends interposed therebetween. And the flange part 152a of the wheel 152 which rotationally moves the upper surface of the strip plate part 140a of these pair of rails 140 latches from the outer side to the edge of each strip plate part 140a. Thereby, lateral blurring during movement of the existing solar cell panel support structure 100 can be suppressed.

  Moreover, in the solar cell panel construction method of the present embodiment, the existing frame 110 is installed on a plurality of cloth foundations 130 installed in parallel to each other on the ground. In the rail installation process, the rails 140 are installed so as to cross and cross the plurality of fabric foundations 130. Thereby, as FIG.3 (b) shows, the existing solar cell panel support structure 100 can be reinstalled also about the position removed from the fabric foundation 130 after a movement.

  Next, a second embodiment will be described.

  The second embodiment is different from the first embodiment described above in that an independent foundation is used as a foundation instead of a cloth foundation. Hereinafter, the second embodiment will be described by paying attention to differences from the first embodiment.

  As shown in FIG. 10, the rail 340 placed on the spacer 350 is fixed to a support leg 311 which is a circular tubular single pipe pile by two U-shaped bolts 341. Each U-shaped bolt 341 has both ends passing through the rail 340 in a state where the outer periphery of the support leg 311 is held, and a nut 342 is fastened to each end. The rail 340 is fixed to the support leg 311 by fastening the nut 342. Such fixing is performed on all the support legs 311 adjacent to each rail 340 in the existing installation base 310 to be moved and the adjacent installation base 310 located on the front side in the moving direction D31.

  Next, with respect to the existing solar cell panel support structure 300 to be moved, an attaching process of the holding device and a moving and fixing process of the existing mount 310 are performed.

  FIG. 11: is a side view which shows the attachment process of the holding | maintenance apparatus in the solar cell panel construction method concerning 3rd Embodiment, and the movement fixed process of an existing mount frame. FIG. 11A shows a side view of the existing solar cell panel support structure 300 to which the holding device 360 is attached and ready for movement. FIG. 11B shows a side view of the existing solar cell panel support structure 300 fixed to the rail 340 after movement. FIG. 12 is a view showing the attaching step of the holding device and the moving and fixing step of the existing gantry as seen from the arrow V31 in FIG. FIG. 12A shows the V31 arrow view in FIG. 11A, and FIG. 12B shows the V31 arrow view in FIG. 11B. Note that the side view of FIG. 11A is a side view taken along the arrow V32 in FIG. 12A so that the attached holding device 360 can be seen without being blocked by the support legs 311. Similarly, the side view of FIG. 11 (b) shows the fixing position of the support leg 311 after moving to the rail 340 as seen from the arrow V32 in FIG. It is a side view.

  In the attaching process, as will be described later, the existing base 310 is removed from the installation location A31 by cutting the supporting leg 311. Prior to that, the holding device 360 is attached to the supporting leg 311. One holding device 360 is attached to each of the six support legs 311 located on the left and right in FIG. 11A and on the left and right and the middle in FIG. 12A.

  FIG. 13 is an enlarged view of the holding device shown in FIGS. 11 and 12. 13 (a) shows an enlarged view of the holding device 360 in FIG. 11 (a), and FIG. 13 (b) shows an enlarged view of the holding device 360 in FIG. 12 (b). Yes. FIG. 13C is a cross-sectional view in a direction perpendicular to the support legs 311, where a rail L-shaped metal fitting 370 to be described later is fixed to the support legs 311.

  The holding device 360 is the same as the holding device 150 according to the first embodiment described with reference to FIG. 5, and includes a jack frame 361 and wheels 362 (rotating bodies). The tip of the elevation protrusion 361b-2a of the main body portion 361b-2 in the jack portion 361b is fixed to the lower surface of the L-shaped metal fitting 361a for bolt fixing to the support leg 311. In response to an operation on the lever 361b-1, the jack L-shaped metal fitting 361a moves up and down together with the lifting protrusion 361b-2a. Further, a wheel 362 is attached to each of the pair of wheel holding frames 361b-3. The flange portion 362 a of each wheel 362 is engaged with the edge of the upper strip 340 a of the rail 340.

  In the attachment step, the following rail L-shaped metal fitting 370 is fixed to the support leg 311 together with the holding device 360. As shown in FIG. 11A, the rail-shaped metal fitting 370 is fixed not only to the support leg 311 to which the holding device 360 is attached, but also to all the support legs 311 adjacent to the rail 340. .

  The rail L-shaped metal fitting 370 is fixed to the upper portion of the support leg 311 above the strip plate portion 340a of the rail 340 so that the lower wall 371 is in contact with the upper surface of the strip plate portion 340a. When attached together with the holding device 360, as shown in FIG. 13, the rail L-shaped metal fitting 370 is fixed so that the lower wall 371 passes between the pair of wheels 362.

  As shown in FIG. 13, the rail L-shaped metal fitting 370 is fixed to the support leg 311 which is a tubular single tube pile by two U-shaped bolts 372. Each U-shaped bolt 372 has both ends penetrating the L-shaped metal fitting 370 for rails in a state where the outer periphery of the support leg 311 is held, and a nut 373 is fastened to each end. By fastening the nut 373, the L-shaped metal fitting 370 for the rail is fixed to the support leg 311. Such fixing is performed on all support legs 311 to which the rail 340 is adjacent.

  When the attachment of the holding device 360 and the fixing of the L-shaped metal fitting 370 for rail described above are finished, the existing base 310 is removed from the installation location A31 by cutting the support legs 311. As shown in FIG. 13, the cut portion of each support leg 311 is a portion where the height from the ground G31 of the installation location A31 coincides with the upper surface of the strip plate portion 340a on the upper side of the rail 34. is there.

  When the mounting process is completed, a moving and fixing process is performed in which the existing solar cell panel support structure 300 is moved and fixed to the rail 340 at the moving destination.

  In the moving and fixing step, first, the existing frame 310 removed from the installation location A31 by cutting is lifted together with the solar cell panel 320 via the six holding devices 360. As a result, the upper part of the support leg 311 to which the jack L-shaped metal fitting 361a is fixed after cutting, that is, the existing frame 310 removed from the installation place A31 is raised with respect to the lower part remaining on the ground G31 side. By this rise, a gap is opened between the upper and lower portions of the support leg 311 as shown in FIG. Further, a gap is also opened between the lower surface of the lower wall 371 of the rail L-shaped metal fitting 370 and the upper surface of the strip plate portion 340 a on the upper side of the rail 340.

  When preparation for movement is completed in this way, the existing frame 310 is moved in the movement direction D31 along with the supported solar cell panel 320 along the rail 340 to an arbitrary movement destination.

  At this destination, the existing frame 310 is lowered and fixed to the rail 340.

  FIG. 14 is an enlarged view of a fixing portion between the existing frame and the rail. FIG. 14 (a) shows an enlarged view corresponding to FIG. 11 (b), and FIG. 14 (b) shows an enlarged view corresponding to FIG. 12 (b).

  As shown in FIG. 14, at the destination, the existing frame 310 is lowered until the lower surface of the lower wall 371 of the rail L-shaped metal fitting 370 contacts the upper surface of the strip 340 a on the upper side of the rail 340. . This lowering position is a position where the upper part where the rail L-shaped metal fitting 370 is fixed in each support leg 311 is shifted from the lower part remaining on the ground G31 side. When the descent is completed, the holding device 360 is detached from each support leg 311. Then, at the lowered position, a hole that communicates the lower wall 371 of the rail L-shaped metal fitting 370 and the upper strip 340a of the rail 340 is processed. Then, the bolt 374 is passed through the hole, and the nut 375 is fastened. With this bolting and fixing, the existing frame 310 is fixed to the rail 340 and the moving and fixing step is completed. With this, the solar cell panel construction method of the present embodiment is completed.

  Needless to say, the solar cell panel construction method according to the third embodiment described above can secure an additional space while reducing the construction cost, as in the first embodiment described above. Moreover, in this embodiment, the existing installation base 310 is reinforced by connecting the support leg 311 with the rail 340 irrespective of whether it is a moving object. In general, a pile driven alone, such as a single pipe pile, may be in an unstable state depending on the situation of the driven site. And the solar cell panel support structure which has the mount comprised with such a pile may be regarded as insufficient intensity | strength although construction was once completed, and the construction needs to be redone. On the other hand, in this embodiment, the reinforcement effect by connection of the support leg 311 by the rail 340 is acquired also about the existing mount frame 310 other than a movement object. For this reason, even if it is considered that the existing frame 310 before the installation of the rail 340 is insufficiently reinforced, the above-described reinforcement effect by the rail 340 can be obtained, so that it is not necessary to perform costly construction rework, etc. The construction cost can also be suppressed in terms of points.

  Moreover, also in the solar cell panel construction method of the present embodiment, a metal rail called C steel is used as the rail 340 to improve the strength. And by providing the spacer 350 between the ground G31 and the rail 340, the rail 340 is installed in a non-contact state with respect to the ground G31. Even in the case where there is no foundation as in the first embodiment or the second embodiment, in this embodiment, by providing the spacer 350 in this way, corrosion or the like due to the rail 340 directly touching the ground G11 is prevented. It can be avoided.

  Moreover, in the solar cell panel construction method of the present embodiment, at least a pair of rails 340 are installed so as to be sandwiched between at least a pair of support legs 311. Thereby, lateral blurring during movement of the existing solar cell panel support structure 300 can be suppressed.

  Next, a fourth embodiment will be described.

  In the fourth embodiment, the support legs of the existing platform are screw piles in which the lower part is embedded in the ground of the installation place without using the foundation, and the rail installation process, the attachment process of the holding device, and the movement fixing process are as follows. This is different from the first embodiment described above in that it is performed on such an existing frame.

  In this embodiment, each rail 440 is placed on a plurality of concrete spacers 450 arranged along the moving direction D41. Thereby, each rail 440 is installed in a non-contact state with respect to the ground G41.

  The three rails 440 installed in this way are fixed to the adjacent support legs 411 as described below.

  FIG. 17 is an enlarged view showing a portion where the rail shown in FIGS. 15 and 16 is fixed to the support leg. FIG. 17A shows a fixed portion to the left support leg 411 in FIG. 16B as a representative example, and FIG. 17B shows a cross section taken along line V43-V43 in FIG. It is shown.

  As shown in FIG. 17, the rail 440 placed on the spacer 450 is placed on the spacer 450 between the joint flange 411a-1 of the screw portion 411a of the support leg 411 and the ground G41. It is fixed in the state. This fixing is performed using two U-bolts 442 in a state where the interposition part 441 is sandwiched between the outer peripheral surface of the screw part 411a and the rail 440. The support leg 411 side of the interposition part 441 is recessed in a semicircular shape so as to coincide with the outer peripheral surface of the screw part 411a, and the rail 440 side is a flat surface. The outer peripheral surface of the screw portion 411a is fitted into the recess of the interposition portion 441, and the rail 440 is pressed against the opposite plane. Each U-shaped bolt 442 penetrates the interposition part 441 and the rail 440 in a state where the outer periphery of the screw part 411a is held, and a nut 443 is fastened to each end part. By fastening the nut 443, the rail 440 is fixed to the screw portion 411a of the support leg 411. Such fixing is performed on all support legs 411 to which the rails 440 are adjacent in the existing base 410 to be moved and the adjacent base 410 located in front of the moving direction D41.

  Next, an attaching process of the holding device and a moving and fixing process of the existing frame are performed on the existing solar cell panel support structure 400 to be moved.

  FIG. 18: is a side view which shows the attachment process of the holding | maintenance apparatus in the solar cell panel construction method concerning 4th Embodiment, and the movement fixed process of an existing mount frame. FIG. 18A shows a side view of the existing solar cell panel support structure 400 to which the holding device 460 is attached and ready for movement. FIG. 18B shows a side view of the existing solar cell panel support structure 400 fixed to the rail 440 after movement.

FIG. 19A shows the view of arrow V41 in FIG. 18A, and FIG. 19B shows the view of arrow V41 in FIG. 18B.

  In the attaching process, as will be described later, the existing base 410 is detached from the installation place A41 by separating the screw part 411a and the circular pipe part 411b in the support leg 411. Prior to that, the support leg 411 of the holding device 460 is removed. Installation to is performed. One holding device 460 is attached to each of the six support legs 411 located on the left and right in FIG. 18A and on the left and right and the middle in FIG. 19A.

  FIG. 20 is an enlarged view of the holding device shown in FIGS. 18 and 19. 20 (a) shows an enlarged view of the holding device 460 in FIG. 18 (a), and FIG. 20 (b) shows an enlarged view of the holding device 460 in FIG. 19 (b). Yes.

  The holding device 460 is substantially the same as the holding device 150 of the first embodiment described with reference to FIG. 5, and includes a jack frame 461 and wheels 462 (rotating bodies). The tip of the elevation protrusion 461b-2a of the main body 461b-2 in the jack portion 461b is fixed to the lower surface of the jack L-shaped metal fitting 461a that is bolted to the circular tube portion 411b of the support leg 411. In response to an operation on the lever 461b-1, the jack L-shaped metal fitting 461a moves up and down together with the lifting protrusions 461b-2a. In response to an operation on the lever 461b-1, the jack L-shaped metal fitting 461a moves up and down together with the lifting protrusions 461b-2a. A wheel 462 is attached to each of the pair of wheel holding frames 461b-3. The flange portion 462a of each wheel 462 is engaged with the edge of the upper strip 440a of the rail 440.

  When the attachment of the holding device 460 described above is completed, a bolt (not shown) that fixes the joint flange 411a-1 of the screw part 411a and the joint flange 411b-1 of the circular pipe part 411b in the support leg 411 is removed. The two are separated. By this separation, the existing mount 410 to be moved is removed from the installation location A41.

  When the attachment process is completed by this separation, a moving and fixing process is performed in which the existing solar cell panel support structure 400 is moved and fixed to the rail 440 at the moving destination.

  In the moving and fixing step, first, the existing frame 410 removed from the installation location A41 is lifted together with the solar cell panel 420 via the six holding devices 460. As a result, the circular tube portion 411a of the support leg 411 to which the jack L-shaped metal fitting 461a is fixed after the separation, that is, the existing frame 410 removed from the installation location A41 is transferred to the screw portion 411b remaining on the ground G41 side. It rises against. As a result of this rise, a gap is opened between the joint flange 411b-1 of the circular pipe part 411b and the joint flange 411a-1 of the screw part 411a as shown in FIG.

  When the preparation for movement is completed in this way, the existing frame 410 is moved in the movement direction D41 along the rail 440 to the arbitrary movement destination together with the supported solar cell panel 420.

  At this destination, the existing frame 410 is lowered and fixed to the rail 440.

  FIG. 21 is an enlarged view of a fixing portion between an existing frame and a rail. FIG. 21 (a) shows an enlarged view corresponding to FIG. 18 (b), and FIG. 21 (b) shows an enlarged view corresponding to FIG. 19 (b).

  In the present embodiment, as shown in FIG. 21, at the movement destination, the existing frame 410 has the height of the lower surface of the joint flange 411b-1 of the circular pipe part 411b and the joint flange 411a-1 of the screw part 411a. It is lowered until the height of the upper surface coincides with each other. Thereby, the height of the solar cell panel 420 in the existing solar cell panel support structure 400 to be moved matches the height of the solar cell panel 420 in the other existing solar cell panel support structure 400. In the present embodiment, the descent of the existing mount 410 is performed as follows.

  The upper surface of the joint flange 411a-1 of the screw portion 411a is at a position higher than the upper surface of the strip plate portion 440a on the upper side of the rail 440. For this reason, the spacer 470 is first fixed to the upper surface of the strip 440a on the upper side of the rail 440 at the destination. When the spacer 470 is fixed to the upper surface of the upper strip 440a of the rail 440, the upper surface of the spacer 470 is formed so as to coincide with the upper surface of the joint flange 411a-1 of the screw portion 411a. The spacer 470 is fixed to the upper strip 440 a of the rail 440 by fastening bolts 471 and nuts 472.

  The descent of the existing frame 410 at the destination is performed until the lower surface of the joint flange 411b-1 of the circular pipe portion 411b contacts the upper surface of the spacer 470. When the descent is completed, the holding device 460 is detached from the circular pipe portion 411b. And the joint flange 411b-1 of the circular pipe part 411b is fixed to this spacer 470 with the volt | bolt 473, a movement fixing process is complete | finished, and the solar cell panel construction method of this embodiment is completed by this.

  Needless to say, the solar cell panel construction method of the fourth embodiment described above can secure an additional space while reducing the construction cost, as in the first embodiment described above. Also in this embodiment, since the support leg 411 as a screw pile that is driven by itself is connected by the rail 440 regardless of whether it is a movement target, the third embodiment described above for the existing mount 410. The same reinforcing effect as in the case of can be obtained. According to this embodiment, construction cost can also be suppressed in this respect.

  Moreover, also in the solar cell panel construction method of the present embodiment, the rail 440 is installed in a non-contact state with respect to the ground G41 by providing the spacer 450 between the ground G41 and the rail 440. Thereby, the corrosion by the rail 440 touching the earth G41 directly can be avoided.

  Moreover, in the solar cell panel construction method of the present embodiment, a pair of rails 440 are installed so as to be parallel with the pair of support legs 411 on the left and right ends. And the flange part 462a of the wheel 462 which rotationally moves the upper surface of the strip plate part 440a of these pair of rails 440 latches on the edge of each strip plate part 440a from the outside. Thereby, lateral blurring during movement of the existing solar cell panel support structure 400 can be suppressed.

  In addition, embodiment described above showed only the typical form of this invention, and this invention is not limited to these embodiment. That is, various modifications can be made without departing from the scope of the present invention. Of course, such modifications are also included in the scope of the present invention as long as the configuration of the solar cell panel construction method of the present invention is provided.

  For example, in the above-described four embodiments, C steel rails 140, 340, and 440 are illustrated as examples of the rails according to the present invention, and the object is controlled by lever operation as an example of the holding device according to the present invention. The holding devices 150, 360, and 460 that move up and down are illustrated. However, the rail and the holding device referred to in the present invention are not limited to these, and may be another example described below, for example.

  FIG. 22 is a diagram illustrating another example of the rail and the holding device. FIG. 22 shows another example of the rail 140 and the holding device 150 of the first embodiment shown in FIG. 22 (a) shows a diagram corresponding to FIG. 5 (a), and FIG. 22 (b) shows a diagram corresponding to FIG. 5 (b). In FIG. 22, the same reference numerals as those in FIG. 5 are assigned to the same components as those shown in FIG.

  In this example, an H steel rail 510 and a holding device 520 having no operation lever are used. The H steel rail 510 is placed on the fabric foundation 130 with the strip portion 510a corresponding to one of the pair of vertical bars in the H shape facing upward.

  Another example holding device 520 includes a jack frame 521 and wheels 522 (rotating bodies). The jack frame 521 includes a first L-shaped metal fitting 521a that is bolted to the support leg 111 of the existing mount 110, and a second L-shaped metal fitting 521b that is attached to the first L-shaped metal fitting 521a so as to be movable up and down. A bolt shaft 521a-2 projects from the lower wall 521a-1 of the first L-shaped metal fitting 521a, and the bolt shaft 521a-2 penetrates the lower wall 521b-1 of the second L-shaped metal fitting 521b. The jack nut 521a-3 is fastened to the bolt shaft 521a-2 with the lower wall 521b-1 of the second L-shaped metal fitting 521b interposed therebetween. By rotating the jack nut 521a-3 and moving it up and down along the bolt shaft 521a-2, the second L-shaped metal fitting 521b moves up and down with respect to the first L-shaped metal fitting 521a. A rail L-shaped metal fitting 160 is bolted to the support leg 111 at a position below the first L-shaped metal fitting 521a.

  A pair of wheel arms 521c extends from the second L-shaped metal fitting 521b toward the rail 510, and a wheel 522 is attached to each tip. When the jack nut 521a-3 is turned to lower the second L-shaped bracket 521b, the relative position of the second L-shaped bracket 521b with respect to the rail 510 is determined by the length of the wheel arm 521c. Will rise. Conversely, when the second L-shaped metal fitting 521b is raised, the first L-shaped metal fitting 521a is lowered. Thereby, the support leg 111 (namely, the existing mount frame 110) to which the first L-shaped metal fitting 521a is bolted is moved up and down.

  Even if the rail 510 and the holding device 520 of the other examples described above are used, the installation space can be secured while suppressing the construction cost, similarly to the solar cell panel construction method of the first to fourth embodiments described above.
