次に、上述のソーラーパネル架台用基礎型枠を用いたソーラーパネル架台基礎の施工工法について説明する。
＜工場にて＞
この実施例１のソーラーパネル架台用基礎型枠では、上述のように構成されるため、先ず、工場において予め２枚の短板型枠パネル１１と２枚の長板型枠パネル１２を平面視で長方形に組み付けられた５枠のコンクリート型枠１と、２本の連結バー２と、間隔保持部材４と、吊金物５を準備し、これらを設置現場まで運ぶ。 Next, the construction method of the solar panel frame foundation using the above-mentioned foundation formwork for the solar panel frame will be described.
<At the factory>
Since the basic form for the solar panel frame of the first embodiment is configured as described above, first, two short plate form panels 11 and two long plate form panels 12 are preliminarily viewed in a plan view at the factory. The five concrete molds 1 assembled in a rectangular shape, two connecting bars 2, a spacing member 4, and a hanging object 5 are prepared and carried to the installation site.

＜現場にて＞
現場では、先ず、２本の連結バー２を敷き並べ水平になるように設置する。
次に、２本の連結バー２相互間において、５枠のコンクリート型枠１を１ｍ間隔のもとに水平かつ同一高さとなるようにレベル及び位置調整して設置する。
次に、コンクリート型枠１に固定された各接続金具３を連結バー２に予め、もしくは現場において開設されたボルト挿通穴２５に挿通し、雄ねじ部３１にナット３２を螺合して締結することにより、両連結バー２−２相互間に５枠のコンクリート型枠１を接続固定し、これを１セットのシステム型枠Ｋとする。なお、図において、６は角鋼管を用いた火打ち、７は桟木である。 <On site>
At the site, first, the two connecting bars 2 are laid and placed horizontally.
Next, between the two connecting bars 2, the five concrete molds 1 are installed with the level and position adjusted so as to be horizontal and at the same height with an interval of 1 m.
Next, each connection fitting 3 fixed to the concrete formwork 1 is inserted into the coupling bar 2 in advance or through a bolt insertion hole 25 established in the field, and a nut 32 is screwed into the male screw portion 31 and fastened. Thus, the five concrete molds 1 are connected and fixed between the two connecting bars 2-2, and this is used as one set of system molds K. In addition, in the figure, 6 is a fire using a square steel pipe, and 7 is a crosspiece.

次に、システム型枠Ｋと路盤との間に砂等を詰めて隙間を塞ぐ。
また、各コンクリート型枠１における左右両長板型枠パネル１２の外周面側である補強用角鋼管１３の外面に沿って上方から間隔保持部材４を差し込んで、補強する。なお、５個のコンクリート型枠１を１ｍ間隔のもとに配置して２本の連結バー２で接続する前に、この間隔保持部材４を用いることにより、コンクリート型枠１、１相互間の配置決めが容易に行えるとともに、コンクリート型枠１、１相互間の寸法精度を高めることができる。
次に、生コン車からシュートを使って各コンクリート型枠１内に直接コンクリートを打設し、木鏝にて天端を均す。 Next, sand or the like is packed between the system formwork K and the roadbed to close the gap.
Moreover, the space | interval holding member 4 is inserted from the upper direction along the outer surface of the square steel pipe 13 for reinforcement which is the outer peripheral surface side of the both left-and-right long plate form panel 12 in each concrete form 1, and it reinforces. In addition, before arrange | positioning five concrete formwork 1 under the space | interval of 1 m, and connecting with the two connection bars 2, by using this space | interval holding member 4, between concrete formwork 1, 1 mutual The layout can be easily determined and the dimensional accuracy between the concrete molds 1 and 1 can be increased.
Next, concrete is placed directly into each concrete formwork 1 using a chute from a ready-mixed car, and the top is leveled with a mallet.

次に、打設したコンクリートが固まった時点で、各間隔保持部材４を上方へ引き抜き、クレーン等にセットされた吊金物５の各フック５３を連結バー２に設けられたフック２４に係合してシステム型枠Ｋを上方に持ち上げることにより、型抜きを行う。   Next, when the placed concrete is hardened, each spacing member 4 is pulled upward, and each hook 53 of the hanging object 5 set on a crane or the like is engaged with the hook 24 provided on the connecting bar 2. The mold is removed by lifting the system mold K upward.

次に、クレーンで持ち上げられたシステム型枠Ｋを次の施工位置に移動して設置し、各コンクリート型枠１にコンクリートを打設する。
なお、前に施工したコンクリート基礎との間隔を１ｍ開けて次のシステム型枠Ｋを設置することにより、ソーラーパネル３機分のソーラーパネル用架台基礎が施工できることになる。 Next, the system formwork K lifted by the crane is moved to the next construction position and installed, and concrete is placed in each concrete formwork 1.
