本発明の実施形態に係る安全ブロック支持構造は、その構成により、以下の効果を有する。
使用状態で水平に延び断面が下方に向いた開口部Оを設けられる矩形の板形状をもつレール部２１の両端に一対の係合部２２を各々に固定され、係合部２２が足場用支柱１０の各々の連結部１２に上から係合する様にしたので、足場用支柱１０に支持されるレール部２１に沿って安全ブロック４０を支持できる。
また、一対の係合部２２を一対の足場用支柱１０の連結部１２に係合するときに開口部Оが斜め前方の下方に向く様にしたので、作業領域の上方に固定すると作業領域に向いた開口部Оに沿って安全ブロックを固定できる。
また、係合部２２の板状部材に連結部１２のコの字状の板形状の嵌まるスリットを設け、板状部材の端面が支柱部１１の側面に当接して連結部１２に係合する様にしたので、安全ブロック用レール２０が足場用支柱１０に固定される。
また、連結部材３１の上部に固定される車輪３２をレール部２１の矩形の板形状の内僻で回転移動させ、開口部Оから下方へ露出する連結部材３１の下部に安全ブロック４０を連結できる様にしたので、安全ブロック４０を安全ブロック用レール２０に沿って移動できる。 The safety block support structure according to the embodiment of the present invention has the following effects due to its configuration.
A pair of engaging portions 22 are fixed to both ends of a rail portion 21 having a rectangular plate shape that is provided with an opening О that extends horizontally in the use state and has a cross section facing downward, and the engaging portions 22 are used as scaffolding struts. Since each of the ten connecting portions 12 is engaged from above, the safety block 40 can be supported along the rail portion 21 supported by the scaffolding column 10.
In addition, when the pair of engaging portions 22 are engaged with the connecting portions 12 of the pair of scaffolding struts 10, the opening О is directed diagonally forward and downward. The safety block can be fixed along the facing opening О.
In addition, the plate-like member of the engaging portion 22 is provided with a U-shaped plate-shaped slit of the connecting portion 12, and the end surface of the plate-like member abuts the side surface of the column portion 11 to engage with the connecting portion 12. Therefore, the safety block rail 20 is fixed to the scaffolding column 10.
Further, the wheel 32 fixed to the upper part of the connecting member 31 can be rotated and moved by the rectangular inner shape of the rail part 21 to connect the safety block 40 to the lower part of the connecting member 31 exposed downward from the opening О. Thus, the safety block 40 can be moved along the safety block rail 20.

本発明は以上に述べた実施形態に限られるものではなく、発明の要旨を逸脱しない範囲で各種の変更が可能である。   The present invention is not limited to the embodiments described above, and various modifications can be made without departing from the scope of the invention.
