次に、図６(ｃ) に示すように、断面略コ字状の支柱３の下端部に該支柱３を水平方向に貫通する横筋８を固定した状態（図７参照）で、該支柱３を鉄筋７の内側に差し込み、支柱３を支柱自立用固定三脚１の固定部４で縦孔６の底部６ａから支柱３を浮かした状態でセットする（第３工程）。   Next, as shown in FIG. 6 (c), in the state in which the horizontal streak 8 penetrating the support column 3 in the horizontal direction is fixed to the lower end portion of the support column 3 having a substantially U-shaped cross section (see FIG. 7). Is inserted into the inside of the reinforcing bar 7, and the support column 3 is set in a state where the support column 3 is floated from the bottom 6a of the vertical hole 6 by the fixing part 4 of the fixing tripod 1 for supporting the support column independently (third step).

次に、図６(ｄ) に示すように、縦孔６にコンクリート９を流し込んで固めることにより、コンクリート９に対し支柱３を垂直状態に立設固定する（第４工程）。   Next, as shown in FIG. 6 (d), the concrete 9 is poured into the vertical hole 6 and hardened to fix the column 3 upright and fixed to the concrete 9 (fourth step).

次に、図６(ｅ) に示すように、固定部４による支柱３の固定を解除して支柱自立用固定三脚１を取り外すことにより、支柱３の設置を完了する（第５工程）。   Next, as shown in FIG. 6 (e), the fixing of the supporting column 3 by the fixing unit 4 is released and the supporting column self-supporting fixing tripod 1 is removed, thereby completing the installation of the supporting column 3 (fifth step).

次に、この実施例１の効果を説明する。   Next, the effect of the first embodiment will be described.

この実施例１のキャストイン・パーカッション方式によるソーラーパネル架台用支柱の設置方法では、上述のように、ロータリーパーカッションドリルで支柱設置用縦孔６の削孔を行うようにしたことで、転石や岩の存否にかかわらず、あらゆる地層の敷地にソーラーパネルを設置することができるようになるという効果が得られる。   In the installation method of the solar panel frame support column according to the cast-in percussion method of Example 1, as described above, the vertical perforation hole 6 was drilled with a rotary percussion drill, so Regardless of whether or not there is an effect, solar panels can be installed on any strata.

また、支柱３と縦孔６の内周面との間の管状隙間に４本の縦筋７１と縦筋７１に溶接固定されたフープ筋７２とで構成される鉄筋７を収容し、縦筋７の内側に支柱３を差し込んだ状態で縦孔６内にコンクリート９を流し込んで固めることにより、縦孔６の径が小さくても、支柱３の横揺れに対するコンクリート９の破壊を防止できるようになる。
これにより、コンクリートの量が少なくてすみ、材料コストの低減が可能になる。
また、縦筋の下端部を孔の底部に打ち込むことにより、鉄筋を孔の中央にバランスよくセットした状態でコンクリートを流し込むことができるようになる。 Further, a reinforcing bar 7 composed of four vertical bars 71 and hoop bars 72 welded and fixed to the vertical bars 71 is accommodated in a tubular gap between the support column 3 and the inner peripheral surface of the vertical hole 6. By pouring the concrete 9 into the vertical hole 6 with the support 3 inserted inside 7, the concrete 9 can be prevented from breaking due to the roll of the support 3 even if the diameter of the vertical hole 6 is small. Become.
Thereby, the amount of concrete can be reduced, and the material cost can be reduced.
Moreover, by driving the lower end of the vertical bar into the bottom of the hole, the concrete can be poured in a state where the reinforcing bar is set in a balanced manner at the center of the hole.

また、支柱３の下端部に該支柱３を水平方向に貫通する横筋８を固定することにより、コンクリート９からの支柱３の引き抜き強度を高めることができるようになる。
また、下部を開いた３本の支持脚１ａ、１ｂ、１ｃの上部結束部２に、支柱３を空中に浮かせた垂直起立状態で自立支持固定可能な固定部４を備えることで、コンクリート９が固まるまでの間コンクリート９内において支柱３を規定のレベル位置で垂直状態に立設維持させることができるようになる。 Further, by fixing the horizontal bar 8 penetrating the support column 3 in the horizontal direction at the lower end portion of the support column 3, the pulling strength of the support column 3 from the concrete 9 can be increased.
Moreover, the concrete 9 is provided with the fixing part 4 that can be supported and fixed in a vertically standing state in which the support column 3 is suspended in the air on the upper binding part 2 of the three support legs 1a, 1b, and 1c with the lower part opened. Until it is hardened, the pillars 3 can be erected and maintained in a vertical state at a predetermined level in the concrete 9.

また、上述のように、支柱３の断面形状を略コ字状とすることで、横筋８によるコンクリートからの支柱３の引き抜き強度をさらに高めることができるようになる。   Further, as described above, by making the cross-sectional shape of the support column 3 substantially U-shaped, the pulling strength of the support column 3 from the concrete by the horizontal bars 8 can be further increased.

また、支柱自立固定三脚（固定手段）１は、下部を開いた３本の支持脚１ａ、１ｂ、１ｃの上部結束部２に、支柱３を空中に浮かせた垂直起立状態で自立支持固定可能な固定部４を備えることで、支柱の下端を縦孔６の底部６ａから浮かせた状態でコンクリート９内に埋め込むことができ、これにより、地中の水分で支柱３の下端から錆を発生させることを阻止することができるようになる。   In addition, the support column self-supporting tripod (fixing means) 1 can be supported and fixed in a self-supporting manner in a vertically standing state in which the support column 3 is suspended in the air on the upper bundling portion 2 of the three support legs 1a, 1b, and 1c that are open at the bottom. By providing the fixing portion 4, the lower end of the support column can be embedded in the concrete 9 in a state of floating from the bottom portion 6 a of the vertical hole 6, thereby generating rust from the lower end of the support column 3 with moisture in the ground. Can be prevented.

また、上述のように、固定部４は、上下２箇所に備えられた上部結束部２と中間の固定部材４３との間に支柱３を挟持固定するもので、支柱受け部４１、４２の形状を平面視で略く字状とすることで、あらゆる断面形状の支柱を挟持固定することができるようになる。   In addition, as described above, the fixing portion 4 is for fixing the support column 3 between the upper binding portion 2 provided at the two upper and lower portions and the intermediate fixing member 43, and the shape of the support receiving portions 41 and 42. By making the substantially square shape in a plan view, it becomes possible to sandwich and fix the pillars having any cross-sectional shape.

また、上述のように、上部結束部２には、水準器５を備えることで、支柱３を容易かつ正確に垂直起立状態にセットすることができるようになり、これにより、作業効率を高めることができるようになる。   In addition, as described above, the upper binding unit 2 includes the level 5 so that the support column 3 can be easily and accurately set in the vertically upright state, thereby improving work efficiency. Will be able to.

また、上述のように、３本の支持脚１ａ、１ｂ、１ｃの内の１本に上部結束部２が固定され、残りの２本が上部結束部２を中心として回動自在に連結されることにより３本の支持脚１ａ、１ｂ、１ｃの側面が互いに重なる状態に折り畳み可能に構成されることで、コンパクトな状態での運搬や収納が可能になる。   Further, as described above, the upper binding portion 2 is fixed to one of the three support legs 1a, 1b, and 1c, and the remaining two are rotatably connected around the upper binding portion 2. Thus, the three support legs 1a, 1b, and 1c can be folded so that the side surfaces thereof overlap each other, thereby enabling transportation and storage in a compact state.
