LOWER CROSSPIECE FOR FRAMEWORK SCAFFOLD AND ITS END COUPLING METAL FITTING
To provide a lower crosspiece for a framework scaffold and an end coupling metal fitting capable of folding a crossing diagonal brace compactly even arranged at the crossing diagonal brace arranged between building frames with a narrow installation interval and also allowing a retrofit to the existing crossing diagonal brace.SOLUTION: A lower crosspiece for a framework scaffold 4 consists of a lower crosspiece body 5 suspended horizontally near downward of a crossing diagonal brace 2 and an end coupling metal fitting 6 mounted to both ends of the lower crosspiece body 5 respectively and coupled to the diagonal brace 2a, 2a. The end coupling metal fitting 6 consists of a sliding metal fitting 7 and a linkage metal fitting 8. The sliding metal fitting 7 is mounted to the diagonal brace 2a slidably in its longitudinal direction. The linkage metal fitting 8 is arranged between the sliding metal fitting 7 and the end of the lower crosspiece body 5 and is coupled rotatably to the sliding metal fitting 7 and the end of the lower crosspiece body 5 in a plane of the crossing diagonal brace 2 by a coupling bolt 9, 10.SELECTED DRAWING: Figure 1
【課題】設置間隔の狭い建枠間に設置された交差筋交いに設置しても、交差筋交いをコンパクト折り畳むことができ、しかも既製の交差筋交いへの後付けも可能にした枠組足場用下桟及び端部連結金具を提供する。【解決手段】枠組足場用下桟4は、交差筋交い2の下方付近に水平に架け渡される下桟本体5と、下桟本体5の両端部にそれぞれ取り付けられ、筋交い2a,2aに連結される端部連結金具6とから構成する。端部連結金具6はスライド金具7とリンク金具8とから構成する。スライド金具7は筋交い2aにその長手方向にスライド自在に取り付ける。リンク金具8はスライド金具7と下桟本体5の端部間に設置し、かつスライド金具7及び下桟本体5の端部にそれぞれ連結ボルト9,10によって交差筋交い2の面内で回転可能に連結する。【選択図】図１
