Description

  The present invention relates to a method of installing a solar panel on a slope including obstacles used for installing a solar panel on a slope including obstacles such as stumps, tree roots, and rocks on a slope such as a mountain or a hill.

In recent years, renewable energy has attracted attention, and a large number of solar power generation systems have been constructed. As a result, on the site where the photovoltaic power generation system is installed, the number of flat places where the equipment is easy to install is reduced, and the slopes such as mountains and hills where the installation of the equipment is difficult tend to increase. In other words, there are few flat lands where solar power systems can be easily installed, and most of the remaining areas are slopes and water surfaces where solar power systems are difficult to install.
When installing a photovoltaic power generation system on a slope such as a mountain or hill, the slope such as the mountain or hill is overgrown with trees and grass. It will be installed through. Such a slope is not flat, has many stumps and tree roots, and is scattered with rocks, etc., and it is often difficult to perform construction on a gantry installed on a flat ground.

A solar panel installation method of this type is proposed in Patent Document 1.
According to the construction method of this document 1 (a solar panel mount and its installation method), a mount supporting the solar panel is formed as a ladder-type mount by vertically or vertically crossing two or more vertical crosses on two or more vertical crosses. Then, install the ladder-type gantry on a slope, ground at least the upper end, middle, upper end, and lower end of the ladder-type gantry, attach a fixing block to these portions, and insert a fixing rod through the fixing block. And stab it in the ground. Then, the solar panels are supported in the partitioned space in the ladder-shaped gantry.

Next, an embodiment for carrying out the present invention will be described with reference to the drawings.
1 to 7 show a solar panel installation method on a slope including an obstacle.
In this solar panel installation method, a gantry made of a core material, a vertical member, and a horizontal member is installed on a slope including an obstacle, and a solar panel is installed on the slope via a gantry. A set shall support a plurality of solar panels, and a set of four or six piles, each having a predetermined diameter and length as a core, and having a bolt through hole at the top, per set As a material, the length can be adjusted for each gantry so that a pair of two vertical materials including a predetermined extra length, and a horizontal material that is approximately the same length as the total length in the horizontal direction of multiple solar panels A pair of two horizontal members having a bolt through hole for sewing (reference numeral 30 in FIG. 5) in accordance with the bolt through hole provided in the solar panel. It consists of a frame approximately the same size as the outer shape of the solar panel. A dummy panel having a through hole is used.
In this case, a steel pile is used as the pile, and the pile is formed with a member strength that can withstand a certain level of unevenness, and plating is performed. Attachments having bolt through holes are previously attached to the upper part of the pile by welding or the like. An angle steel made of a highly corrosion-resistant plated steel sheet is used for a vertical member, and a Z-shaped steel made of a highly corrosion-resistant plated steel sheet is used for a cross member. Since the solar panels are sewn on the horizontal member in units of a plurality of bolts with bolts and nuts, bolts provided on each solar panel in advance for each of the plurality of solar panel installation positions on the horizontal upper surface of the horizontal member in advance. Drill the bolt holes according to the holes. The dummy panel is formed by joining the upper frame, the lower frame, and the left and right side frames made of a steel plate into a rectangular shape approximately the same size as the outer shape of a single solar panel, and the upper and lower portions between the left and right side frames. Two reinforcing frames made of a steel plate are joined and formed in parallel with the frame, and bolt through holes are formed in the upper frame and the lower frame corresponding to the bolt through holes of the solar panel.
Also, in this case, the basic form is to reduce the number of members of the mount and to install three solar panels side by side on one mount to form one set so that the mount can be carried by human power. On slopes without obstacles, the gantry has a structure in which two pairs of cross members are assembled on a pair of vertical members in a regular cross-girder shape, and this is supported by four (six if necessary) piles. This is basically used even on slopes with obstacles, but in order to avoid obstacles, the position of piles (pile holes) and the length and direction of the vertical members are arbitrarily changed to provide a pair of vertical members and a pair of vertical members. Corresponding to the cross-members of the above is assembled in a special cross-shaped girder.
In addition, when about 300 solar panels of about 1.5 m in length and about 1 m in width are to be installed on a slope including obstacles, 100 sets of three sets are required. In this case, a pile (φ65 mm , L = 0.675 m or more) 400 pieces, vertical material (about 3 m) 100 pieces, horizontal piece (about 3 m) 200 pieces, bolt and nut (M-10, M-8) Prepare the number, adding a premium to each number. It can be said that the number of materials is small for 100 frames.
And, in this construction method, using this small material, through the drilling step, the gantry temporary assembling step, the gantry marking step, the gantry on-site processing step, the gantry assembling step, the pile fixing step, and the solar panel mounting step, on the slope including obstacles A large number (for example, 100) of gantry is installed, and a large number (for example, 300) of solar panels are installed on the slope through the large number (for example, 100) of gantry.

(Punching step)
In the drilling step, as shown in FIG. 2, a pile hole 10 is drilled at a pile position which is positioned at two places in a vertical direction and two rows at a time in three places per one stand on a slope. If there is an obstacle at any of the pile positions, the horizontal distance is within the length of the horizontal member, the vertical distance is within the length of the vertical member, Drill a hole 10 at the dodged position.
In this step, the area where solar panels can be installed on the slope after cutting and cutting grass as shown in FIG. 1 is specified, and in this area, first, four solar panels per stand (if necessary) The positions of the six piles). Basically, this ink mark is taken in accordance with the position of the standard four fulcrums (four intersections of the vertical and horizontal members or the vicinity thereof) of the frame assembled in a girder shape on one installation surface of the frame. If there is an obstacle at the position of the stake, the position of the stake is set within the range of the length of the stub, the interval of the stake is within the length of the Change to an arbitrary position by straddling or dodging. For example, if there is an obstacle at the position of the pile on the upper slope, take the position of the pile above the obstacle and straddle the obstacle, or take the position of the pile in the left and right direction of the obstacle and dodge the obstacle. . In addition, if there is an obstacle at the position of the pile below the slope, take the position of the pile below the obstacle and straddle the obstacle, or take the position of the pile in the left and right direction of the obstacle and Dodge.
In this way, the position of the pile is determined on the slope including the obstacle, and the pile hole 10 is drilled manually or mechanically with an attach drill.

(Temporary gantry assembly step)
In the gantry temporary assembling step, as shown in FIG. 3, the piles 11 are installed in the vertical pile holes 10 drilled in the drilling step, and the vertical members 2 are temporarily erected between the respective vertical piles 11. The dummy panel 4 is mounted between the horizontal members 3 by inserting bolts (M8) into the respective bolt holes and tightening the nuts, and the positions of the horizontal members 3 temporarily fixed in parallel and parallel are adjusted between the vertical members 2. Then, the gantry 1 is temporarily assembled.
In this step, as shown in FIG. 8, first, four piles 11 are inserted into four (sometimes six) pile holes 10 drilled in the drilling step, and each pile 11 is inserted between the respective vertical piles 11. Hang each vertical member 2. At this time, each pile 11 and each vertical member 2 are fixed and held by a vise (vise). In this case, when the four pile holes 10 correspond to the four standard fulcrums of the gantry 1, the vertical members 2 are laid in substantially parallel at the same vertical position on the slope. Then, the horizontal members 3 temporarily fixed by the dummy panels 4 on these vertical members 2 are bridged substantially orthogonally. After adjusting the position of each horizontal member 3, each vertical member 2 and each horizontal member 3 are fixed and held by a vise. In this way, the gantry 1 is assembled in a regular cross-girder shape. Further, in this case, when a part or all of the four pile holes 10 straddle or dodge an obstacle, each of the vertical members 2 is one of the vertical members of the gantry 1 installed at a position where there is no obstacle. 2, or one of them is displaced up and down with respect to the other (on the slope), or one is oblique to the other, or both are substantially U-shaped or substantially inverted It is bridged in a C-shaped arrangement or a combination of these. Then, the horizontal members 3 temporarily fixed by the dummy panels 4 are crossed over these vertical members 2 and are bridged. After adjusting the position of each horizontal member 3, each vertical member 2 and each horizontal member 3 are fixed and held by a vise. In this way, the gantry 1 is assembled into a modified cross-girder shape. In addition, the required span of each vertical member 2 and the penetration length and free length of each pile 11 are selected from the maximum and minimum panel installation angles based on the wind load determined in advance for each solar panel installation site.

(Frame marking step)
In the gantry marking step, as shown in FIG. 4, from the gantry 1 temporarily assembled in the gantry temporary assembling step, the joining positions of the bolt through holes 110 of the respective stakes 11 to the respective vertical members 2, the respective vertical members 2 and The joining position with the horizontal member 3 is marked, and the cutting position corresponding to the extra length of the vertical member 2 is marked unless the vertical member 2 has no extra length.
In this step, the position to be fixed to the side surface of each vertical member 2 (in this case, the vertical surface of the angle iron) with the bolt through hole 110 of each pile 11 and the upper surface of each vertical member 2 (in this case, the horizontal plane of the angle iron) ) And the lower surface of each cross member 3 (in this case, the lower horizontal surface of the Z-section steel) is marked with a punch or the like at a position to be fixed with a bolt. When the gantry 1 is assembled in a regular cross-girder shape, the vertical members 2 have the same length as the horizontal members 3. In this case, if one vertical member 2 is approximately 3 m as described above, by dividing into two equal parts, two vertical members 2 of the gantry 1 can be obtained. By taking two vertical members 2 from the two vertical members 2, no extra length is generated in each vertical member 2. In this case, there is no need to mark the cutting position for the extra length on each vertical member 2. On the other hand, when the gantry 1 is assembled in a modified cross-girder shape, each vertical member 2 has a different length. In this case, one or both of the vertical members 2 have an extra length, and the extra length is generated. For cutting, the cutting position corresponding to the extra length of the vertical member 2 is marked.

(Mounting on-site processing step)
In the gantry site processing step, as shown in FIGS. 4 and 5, the gantry 1 marked by the gantry marking step is dismantled while leaving each pile 11 in each pile hole 10, and each vertical member 2, each cross member The bolt passing holes 21, 22, 32 are drilled at the joining positions marked 3 and cut at the cutting positions where the extra length of the vertical members is marked.
In this step, bolt through holes 21, 22, and 32 are formed in each of the vertical members 2 and each of the horizontal members 3 by punching with a punching machine, and the remaining length of the vertical member 2 is cut by a cutting machine.

(Mounting steps)
In the gantry assembling step, as shown in FIG. 6, the vertical members 2 processed in the gantry on-site processing step are erected between the piles 11 in the vertical direction, and each of the horizontal members 3 to which the dummy panel 4 is attached is connected to each of the vertical members. The two bolt holes 110 (see FIG. 4) and 21 (see FIG. 5) which are installed between the members 2 and serve as joining positions of the respective stakes 11 and the respective vertical members 2, the respective vertical members 2 and the respective horizontal members 3. The two bolt through holes 22 and 32 (see FIG. 5) at the joining position with the bolts are aligned with each other, bolts (M10) are passed through and nuts are fastened to assemble the gantry. The height is adjusted to a predetermined height, and the height of each pile 11 is maintained by attaching the fall prevention jig 5 to each pile 11 or the vertical member 2 or the horizontal member 3.
In this step, as shown in FIG. 9, each vertical member 2 is bridged between each vertical stake 11 inserted into each vertical stake hole 10, and the bolt through hole 110 of each stake 11 is connected to each vertical stake 11. The bolt through holes 21 of the material 2 are aligned, a bolt (M10) is passed between these bolt through holes 110 and 21, and a nut is fastened to fix them. In this case, when the four pile holes 10 correspond to the four standard fulcrums of the gantry 1, the vertical members 2 are bridged in substantially parallel with the same vertical position on the slope. Then, the respective horizontal members 3 temporarily fixed by the dummy panel 4 are bridged on the substantially parallel vertical members 2 in a substantially orthogonal manner, and bolts of both bolts at the joining positions of the respective vertical members 2 and the respective horizontal members 3 are passed. The holes 22 and 32 are aligned with each other, and a bolt (M10) is inserted between these bolt through holes 22 and 32 to fasten a nut. In this way, the gantry 1 is assembled in a regular cross-girder shape. Further, in this case, when a part or all of the four pile holes 10 straddle or dodge an obstacle, each of the vertical members 2 is one of the vertical members of the gantry 1 installed at a position where there is no obstacle. 2, or one of them is displaced up and down with respect to the other (on the slope), or one is oblique to the other, or both are substantially U-shaped or substantially inverted It is bridged in a C-shaped arrangement or a combination of these. Then, the cross members 3 temporarily fixed by the dummy panels 4 are crossed over the vertical members 2 that straddle or dodge these obstacles so as to be crossed over, and become the joining positions of the respective vertical members 2 and the respective horizontal members 3. The two bolt holes 22 and 32 are respectively aligned, and a bolt (M10) is inserted between the bolt holes 22 and 32 to fasten a nut. In this way, the gantry 1 is assembled into a modified cross-girder shape. After assembling the gantry 1, each of the piles 11 in each of the pile holes 10 is adjusted to a predetermined height determined at the construction site, and the scissors are placed on the periphery of the pile hole 10 with the peripheral surface of each of the piles 11 interposed therebetween. Each of the pile holes is formed by using a drop-preventing jig 5 (with a non-slip rubber attached to a portion sandwiching the pile 11) or a column-shaped drop-preventing jig 5 that supports the vertical member 2 or the horizontal member 3. Each pile 11 in 10 is held at a predetermined height.

(Pile fixing step)
In the pile fixing step, as shown in FIG. 6, after the gantry assembling step, each pile hole 10 is filled with expanded cement milk and solidified, and the pile 11 is fixed in each pile hole 10 to expand the expanded cement milk. After the solidification, the fall prevention jig 5 is removed from the gantry 1.

(Steps for mounting solar panels)
In the solar panel mounting step, as shown in FIG. 7, after the pile fixing step, a plurality of solar panels S are arranged on the pair of cross members 3 instead of the dummy panel 4, A bolt (M8) is inserted between the bolt through hole 30 for sewing the cross member 3 (see FIG. 5) and the bolt through hole of each solar panel S, and a nut is fastened. The solar panels S are sewn in units of a plurality of sheets.
In this step, as shown in FIGS. 9 and 10, the bolts (M8) for fixing the dummy panel 4 are removed from the pair of cross members 3 which are installed and fixed between the vertical members 2 by bolts, and each horizontal member is removed. The dummy panel 4 is removed from the timber 3, and the solar panels S are arranged in units of a plurality of sheets, in this case, in units of three, on each of the timbers 3. Each of the solar panels S is sewn on each of the cross members 3 by passing bolts (M8) between the bolts and the bolts of the solar panel S and fastening the nuts.

  Through the above steps, the solar panel S is installed on the slope including the obstacle.

As described above, in this solar panel installation method, a plurality of solar panels are supported by one set of gantry, and each gantry has a predetermined diameter and length as a core material with one set of gantry. Four or six piles 11 each having a bolt through hole 110 at the top, and a pair of two vertical members 2 having a length including a predetermined extra length so that the length can be adjusted for each frame as a vertical member, and a horizontal member A pair of two cross members each having substantially the same length as the total length in the lateral direction of a plurality of solar panels and having a bolt through hole 30 for sewing in accordance with a bolt through hole provided in the solar panel. 3. A dummy for a temporary assembly of a pair of two horizontal members 3 having a frame having substantially the same size as the outer shape of the solar panel, and having a bolt through hole 40 corresponding to the bolt through hole 30 of each horizontal member 3. Since the panel 4 is used to assemble with bolts and nuts, The materials required for the less, by human power even less to transport these materials and equipment equipment, it is possible to reduce the costs, including materials costs and labor costs. Further, as the material of the gantry 1 is small, the time required for assembling the gantry 1 is shortened, and the construction period can be shortened.
In addition, according to this construction method, in the drilling step, the pile hole 10 is drilled at the position of the pile 11 of the gantry 1, and when there is an obstacle such as a stump or a tree root at the position of the pile 11, the obstacle is straddled or dodged. Drill a stake hole 10 in the position, and through the following gantry temporary assembling step, gantry marking step, and gantry on-site processing step, the vertical member 2 having a sufficient length can be used in the place where there is no obstacle and where there is no obstacle. The bolts 21, 22, and 32 are punched out at the positions of the vertical members 2 and the horizontal members 3 that are positioned at the site. Since the members 2, the vertical members 2 and the horizontal members 3 are directly fixed by bolts and nuts, the gantry 1 can be flexibly assembled and installed according to the ground conditions at the site of the slope including obstacles. In addition, since the pile 11, the vertical member 2, and the horizontal member 3 are directly fixed by bolts and nuts, there is no welding or gas cutting, and there is no damage to each member. Furthermore, since each horizontal member 2 is temporarily fixed via the dummy panel 4 and fixed on each vertical member 2, the distance between the horizontal members 3 is the same as that of the solar panel S and the dummy panel 4 having the same outer shape. When the solar panel S is mounted on each horizontal member 3 instead of the dummy panel 4, the bolt holes of the solar panel S and the bolt holes 30 of each horizontal member 3 are easily aligned. If there is an obstacle on the pair of vertical members 2 laid between the piles 11 in the respective vertical directions from the gantry assembling step through the pile fixing step and the solar panel mounting step, if there is an obstacle, A pair of cross members 3 temporarily fixed by a dummy panel 4 are erected on the pair of crossed vertical members 2, and the pair of cross members 3 are replaced with the dummy panel 4 and a plurality of (three) units of sunlight Since the panel S is sewn with bolts and nuts, it is easy to fix the solar panel S to each of the cross members 3, and it is possible to easily install the solar panel on a slope including obstacles.
