Japanese Patent JP2016017316

A

PROBLEM TO BE SOLVED: To provide a binding device for a wedge binding-type scaffold of a simple structure.SOLUTION: A binding device for a wedge binding-type scaffold comprises a bracket fixed on a column and formed into a U shape when seen in a planar direction, and an engaging metal fitting installed at an edge part of a wooden arm member. The engaging metal fitting comprises a wedge guiding member and a wedge. The wedge guiding member includes: a perpendicular part fixed at a notched edge at front ends on right and left sides of a recessed part of the U-shaped tubular wooden arm member, at a mid-point of the length; an inclined lower edge part; a pointed tool insertion hole opened at a top edge of the perpendicular part; a rearward protrusion formed below the insertion hole; and a flat spring curved rearward fitted on the rear protrusion at a central hole, with a top edge and a bottom edge of the flat spring coming in contact with the perpendicular part. The wedge includes: a bent part at a top end being bent horizontally rearward; a perpendicular part and an inclined lower edge part similar to the perpendicular part and the inclined lower edge part of the wedge guiding member; a pointed tool insertion hole opened at a top edge of the perpendicular part; and a long guide hole formed below the insertion hole, for inserting the rearward protrusion that penetrates through the curved flat spring of the wedge guiding member.SELECTED DRAWING: Figure 4
