DIAGONAL BRACE CONNECTION STRUCTURE FOR SCAFFOLD
PROBLEM TO BE SOLVED: To provide a diagonal brace connection structure for a scaffold that enables a diagonal brace of a scaffold to be fitted readily on a support post and removed by an extremely simple operation.SOLUTION: A diagonal brace connection structure for a scaffold comprises a body metal fitting H that includes: two plate metal fittings on right and left provided with a slanted diagonal brace connection pipe 3 into which an end of a diagonal brace rod 2 may be inserted; an engagement insertion piece hanging from a tip of the metal fitting; a bracket holding piece connected swingably to the metal fitting; a wedge regulating piece spanned between base parts of the metal fitting; a wedge insertion space formed among the metal fittings, the wedge regulating piece and the bracket holding piece; a wedge piece 6 inserted into the space; and a pull-out hole 10 of the wedge piece 6. A space between an inner top edge 19 of the pull-out hole 10 and a top edge 20 of the plate metal fitting is formed to be large enough to accommodate a wire tightening tool X. The configuration should allow leverage to be utilized effectively for releasing a top piece of the wedge piece 6, the leverage deriving from the wire tightening tool X engaged with a thick wall part of the plate metal fitting and the inner top edge 19 of the pull-out hole 10.SELECTED DRAWING: Figure 7
【課題】足場用筋交を支柱に容易に取り付けることができ、極めて簡単な操作で取り外すことができる足場用筋交連結構造を提供する。【解決手段】足場用筋交連結構造は、筋交ロッド２の端部を挿入可能な筋交連結パイプ３を傾斜して設けた左右二枚のプレート金具と、該金具先端部に垂設した係合差込片と、該金具に揺動自在に連結したブラケット挟持片と、該金具の基部間に架設したくさび規制片と、該金具の間とくさび規制片とブラケット挟持片との間に形成したくさび挿入空間と、該空間に挿入したくさび片６と、くさび片６の引抜き用孔１０と、より本体金具Ｈを構成し、引抜き用孔１０の内径上端縁１９とプレート金具の上端縁２０との間の空間は、しの工具Ｘが挿入可能な大きさに形成し、くさび片６の上片解除のために、しの工具Ｘによりプレート金具の肉厚部と引抜き用孔１０の内径上端縁１９とに係合して行うてこ作用を有効に発揮可能な関係にそれらを構成する。【選択図】図７
