As shown in FIGS. 1 to 5, a solar panel support construction jig 10 according to an embodiment of the present invention has a solar panel on a rectangular mold 12 in plan view having a flange 11 around the upper side. The support column 13 that supports is temporarily fixed.

The formwork 12 is configured by combining steel panel plates 15 having flanges around them, creating a space 16 having a required size inside, and fixing each panel plate 15 with a simple gripping tool such as a giant clam. Then, necessary reinforcing bars are applied to the internal space 16, the support column 13 is temporarily fixed by the solar panel support building jig 10, and concrete is filled in the mold 12 to form a foundation. These will be described in detail below. In FIG. 1, PP is the short width direction and QQ is the long direction.

A solar panel support construction jig 10 includes a horizontal beam 18 having a square cross-section having a length straddling the formwork 12 in the short width direction, and legs 19 and 20 provided in pairs with the horizontal beam 18. And a temporary fixing member 21 that temporarily fixes the support column 13 at a predetermined angle at an intermediate position of the horizontal beam member 18. In this embodiment, the horizontal beam 18 uses a steel square pipe having a thickness of 1.6 mm and a square of 50 mm. However, the present invention may also be used in cases where the dimensions, thickness and material are different (for example, aluminum squares). Applied. In this embodiment, the horizontal beam 18 is arranged in the short width direction, and further, since a square pipe is used, it is lighter than a square steel pipe arranged over the conventional longitudinal direction. That's it.

As shown in FIGS. 2 (A) and 2 (B), the horizontal beam member 18 has a first through hole 23 that penetrates in the vertical direction and pairs in the short width direction, depending on the dimensions of the mold 12. 24 (when the inner width of the mold 12 is 1200 mm) is provided. The distance between the centers of the first through holes 23 and 24 is such that the inner dimension of the mold 12 is k (1200 mm), the width of the flange 11 is w (for example, 50 mm), and the width of the legs 33 and 34 is s ( 50 mm), (k + 2w + s) = 1350 mm. The third through holes 25 and 26 are formed at an interval of 750 mm with k = 600 so that it can be used even when the inner width of the mold 12 is 600 mm. The present invention is not limited to this dimension and may have other dimensions according to circumstances.

FIG. 1 shows an example in which the inner width of the mold 12 is 600 mm, and FIG. 2 shows an example in which the inner width of the mold 12 is 1200 mm.
The first through holes 23 and 24 and the third through holes 25 and 26 are symmetrical with respect to the center in the length direction of the horizontal beam member 18 and are provided at intermediate positions in the width direction of the horizontal beam member 18. Yes.

The leg members 19 and 20 are attached to the outer side of the horizontal beam member 18 so as to be slidable, and are connected to the horizontal beam member 18 by pins 28 and 29 at predetermined positions. Legs 33 and 34 that are vertically disposed directly below the centers of 30 and 31, and fixed at midway positions of the legs 33 and 34, are mounted on the flange portion 11 of the mold 12, and the horizontal beam member 18 is attached to the mold 12. Horizontal support members (consisting of angle members) 36 and 37 which are kept at a fixed height position. Thus, the solar panel support construction jig 10 can be installed at a certain height with respect to the mold 12.

Second through holes 38 and 39 (see FIGS. 3 and 5) through which the pins 28 and 29 can vertically pass are provided at the central positions of the rectangular tube portions 30 and 31. As a result, the pins 28 and 29 are inserted into the first through holes 23 and 24 or the third through holes 25 and 26 and the second through holes 38 and 39, and the legs 19 and 20 are moved to the horizontal beam members. It can be fixed at 18 predetermined positions (distance between centers is 750 mm or 1350 mm).

In this embodiment, the pins 28 and 29 are made of steel rods bent in an L shape having a diameter of 12 to 13 mm. The gap between the rectangular tube portions 30 and 31 and the horizontal beam member 18 is very small, and it is possible to move the rectangular tube portions 30 and 31 along the horizontal beam member 18, but it is not possible to wobble in the mounted state. Absent. In addition, the rectangular tube parts 30, 31 and the leg parts 33, 34 and the horizontal receiving members 36, 37 constituting the leg members 19, 20, respectively, are firmly joined by welding.

Next, the temporary fixing member 21 provided at the approximate center of the horizontal beam member 18 will be described. As shown in FIG. 4, the temporary fixing material 21 is configured by welding and joining a mounting portion 41 made of a metal (for example, steel) square pipe and a guide portion 42 made of an angle material, and the mounting portion 41 is a horizontal beam. The material 18 is fixed by screws with a single bolt 44 and a nut 45 at a substantially central position. Therefore, when the nut 45 is loosened, the angle between the temporary fixing member 21 and the horizontal beam member 18 can be arbitrarily changed (that is, tilted). This is because the temporary fixing member 21 can be tilted with respect to the horizontal beam member 18 when the column 13 is temporarily fixed to the inclined surface having a slight angle by using the solar panel column building jig 10. I am doing so.

The guide member 42 is made of an angle material so that the support column 13 can be fixed along the temporary fixing material 21 by using the inner orthogonal surface of the angle member. For the fixing, a traditionally used giant killer whale is used. In this embodiment, the support column 13 and the guide portion 42 are fixed by the scale 108. However, the mounting portion 41 (consisting of a square pipe) and the support column 13 can be fixed by the scale.

The temporary fixing material 21 is formed vertically symmetrically around the position of the insertion bolt hole of the bolt 44. Then, as shown in FIG. 2, when the guide portion 42 is directed to the right, the support column 13 to be mounted is attached to the horizontal beam member 18 so as to be the center position in the short width direction of the formwork 12. The position of the bolt 44 is determined. In addition, if this temporary fixing material 21 is replaced with another one, the support column 13 can be disposed at any required position. The guide part 42 is disposed along the support column 13.

The position of the lower end of the temporary fixing member 21 is higher than the lower end positions of the horizontal receiving members 36 and 37 provided on the leg members 19 and 20. Thus, when the solar panel support construction jig 10 is installed, the lower end of the temporary fixing material 21 is not buried in the concrete. The solar panel support construction jig 10 can be disassembled into a horizontal beam member 18, leg members 19, 20, temporary fixing member 21, nut 45, pins 28, 29, and can be assembled on site.

Next, a method for constructing the solar panel support 13 using the solar panel support constructing jig 10 will be described. First, the mold 12 is formed at a predetermined position. Then, the solar panel support construction jig 10 assembled in advance is placed on the mold 12. In this case, the horizontal receiving members 36 and 37 of the leg members 19 and 20 are placed on the flange portion 11 of the mold 12.

In addition, the arrangement position of the column construction jig 10 of the solar panel in the longitudinal direction of the mold 12 is measured in advance, and a mark line is written on the flange portion 11 of the mold 12. The temporary fixing member 21 is attached to the horizontal beam member 18 at a predetermined angle.
In this state, the support column 13 is set on the guide portion 42 of the temporarily fixing material 21 and fixed with the scales. After that, the concrete is put in the mold 12 and cured and hardened. Then, the scale 1047 is removed, and the solar panel prop construction jig 10 is removed to complete the construction.

The present invention is not limited to the above-described embodiment, and the shape and size of the member can be changed without changing the gist of the present invention.
Moreover, in the said embodiment, although steel materials are used as a member, stainless steel, aluminum material, and a synthetic resin material may be sufficient depending on the case.
Further, in the above-described embodiment, the case where two support columns are set up on a common foundation has been described. However, when one or three or more support columns are set up on one foundation, the solar panel support building jig is also provided. Can be used.
