  However, the solar panel mount described in Patent Document 1 has a large number of parts such as bolt fastening parts and reinforcing members, and there are many fastening points by bolts and nuts, so that the construction work is very complicated and the work time is long. It was.

  The present invention has been made in view of such problems, and an object thereof is to provide a solar panel gantry and a construction method thereof that can be constructed with a small number of parts and can be constructed with simple operations.

  Therefore, in the construction method of the solar panel gantry according to the present invention, in constructing the gantry for installing the solar panel on the surface to be installed, the concrete foundation provided at the position of each vertex of at least the rectangle of the surface to be installed. On the upper side, an upper and lower mold form having an upper edge inclined at an angle corresponding to the inclination angle of the gantry is provided so that one in the inclination direction is low and the other is high. A base rail having a shape with a lower side is mounted and positioned and held, and a joist is mounted on the upper side of the base rail and connected with a mounting bolt, while an anchor bolt protrudes downward on the lower side of the base rail. In this case, the frame is assembled and fixed, the concrete is placed in the above-mentioned formwork, and the anchor bolt is embedded and fixed to the concrete column.

  A first feature of the present invention is that a mold frame having an inclined upper edge is assembled on a concrete foundation, a base rail having a cross-sectional shape having an upper side and a lower side is mounted on the mold, and is positioned and held. A joist is mounted on the upper side, the upper side and the joist are connected with a mounting bolt, and an anchor bolt is fixed to the lower side of the base rail to constitute a frame. Thereby, the stand for solar panels can be assembled with a small number of parts.

  The second feature of the present invention resides in that a gantry is assembled on a formwork, and concrete is placed in the formwork and solidified in that state. As a result, when the cast concrete is solidified, the anchor bolt is embedded and fixed in the concrete support, so that the gantry and the support can be fixed easily and securely, and the work can be easily performed. Shorter work time.

  The base rail may be mounted so as to extend between the high and low molds, but if the H-shaped steel is used for the base rail, it is heavy and it is difficult to position and hold the base rail. Therefore, it is preferable to mount the base rail so as to extend between the molds having the same height.

  The joists need only be mounted on the base rail and may be inclined with respect to the base rail. However, in consideration of mounting a solar panel and mounting it stably, the joists should be orthogonal to the base rail and parallel to each other. It is good.

  The concrete foundation may be provided at least at the position of each vertex of the rectangle, and the concrete foundation can also be provided in the middle of the rectangular side.

  Further, the base rail may be a member having a cross-sectional shape having an upper side portion and a lower side portion. For example, as shown in the following embodiment, an H-shaped steel can be adopted, but an equivalent strength is obtained. It is also possible to employ steel materials such as Z-shaped steel, groove-shaped steel, hat-shaped steel and the like.

  Absorption of unevenness on the floor surface and change of the inclination angle of the gantry can be done by adjusting the height of the concrete foundation, so if the mold is prepared with a fixed mold with high and low mold Of course, of course, molds of various heights may be prepared and selected for use.

  The base rail is positioned and held by attaching a locking tool to the upper edge of the formwork, for example, driving a nail or screwing a screw and positioning and holding the base rail by this locking tool (nail or screw). .

  When connecting joists and base rails with mounting bolts, insertion holes can be formed in the base rail and joists in advance, the mounting bolts can be inserted into the insertion holes, screwed into the nuts, and then tightened. . Further, when the anchor bolt is fixed to the base rail, an insertion hole can be formed in the base rail in advance, and the anchor bolt can be inserted into the insertion hole and screwed into the nut to be fixed.

  The solar panel mount constructed by the method of the present invention is also novel. That is, according to the present invention, in the platform for installing the solar panel, the concrete foundation provided at the position of each vertex of at least the rectangle of the surface to be installed, and the top surface at an angle corresponding to the inclination angle of the platform The concrete foundation is inclined and has a high and low concrete pillar provided on the concrete foundation so that one of the inclination directions is low and the other is high, and a cross-sectional shape having an upper side and a lower side. A base rail mounted on the base rail, an anchor bolt that protrudes downward and is fixed to the lower side of the base rail, and is fixed to the concrete column to fix the base rail to the concrete column; and Mounted on the upper side and connected with mounting bolts for solar panels, characterized in that It is possible to provide a platform.

As shown in FIG. 4, the base rail 11 is made of H-shaped steel and is mounted on the mold 16 so that the H-shaped steel has a horizontal H shape and extends between the molds 16 having the same height. A nail (locking tool) 18 is driven into the upper edge 16A of the mold 16 to position and hold the base rail 11. Instead of the H-section steel, a member having a cross-sectional shape having an upper side portion and a lower side portion and having a strength equivalent to that of the H-section steel, for example, a Z-shape steel, a channel shape steel, a hat shape steel, or the like can also be used.

  On the other hand, a C channel having a U-shaped cross section is used for the joists 12, and a plurality of, for example, six joists 12, are parallel to each other with a predetermined interval, for example, an interval corresponding to the lateral width of a solar panel module (not shown). And mounted on the base rail 11 so as to be orthogonal to the base rail 11.

  Next, as shown in FIGS. 5 and 6, the bolt 13 </ b> A is inserted into a bottle insertion hole formed in advance in the upper side of the side H of the base rail 11 and the U-shaped lower side of the joist 12. Then, the base rail 11 and the joist 12 are connected to each other by screwing into the nut 13B. The other joists 12 are similarly connected to the base rail 11 by mounting bolts 13 including bolts 13A and nuts 13B.

  Further, a J-shaped bolt 14A is inserted from below into a bolt insertion hole formed at a position corresponding to the support on the lower side portion of the horizontal H shape of the base rail 11 and fixed to the nut 14B. Similarly, the anchor bolt 14 including the J-shaped bolt 14A and the nut 14B is fixed to the other end side of the base rail 11 and the other base rail 11 as well.

  When the gantry 10 is assembled on the mold 16 in this way, as shown in FIG. 3, when the concrete 30 is placed in the mold 16 and solidified, and then the mold 16 is released, it is shown in FIG. 7. Thus, the column 20 in which the anchor bolt 14 is embedded and fixed in the solidified concrete is completed, and the solar panel mount is completed.

  As described above, the mold 16 having the upper edge portion 16A inclined at an angle corresponding to the inclination angle of the gantry 10 is assembled on the concrete foundation 15, the base rail 11 is mounted on the mold 16, and the nail 18 is attached to the mold. The base rail 11 is positioned and held by being driven into the upper edge portion 16A of the base plate 16.
