PROBLEM TO BE SOLVED: To provide a binding device in a structurally simple wedge binding type scaffold.SOLUTION: A binding device in a wedge binding type scaffold is composed of a receiving metal fitting of a column and a locking metal fitting of a bracket material end part. The receiving metal fitting is a U shape when viewed from a plane. The locking metal fitting is composed of: a vertically long plate-like wedge composed of a U-shaped part, an upward dog-legged part and a downward dog-legged part downward from above; a wedge guide member provided with a backward projecting peripheral edge on a vertical wall, fixing its rear upper part to the bracket material front end, forming a downward step part for hooking on the receiving metal fitting in its lower part, forming a lower part than this as a receiving metal fitting penetration part, fitting in the wedge by leaving the U-shaped part above the backward projecting peripheral edge from a recessed part of the backward projecting peripheral edge upper end, contacting the bending front end of the upward dog-legged part of the wedge with the vertical wall, contacting an upper half of the downward dog-legged part with a central wall of the receiving metal fitting and formed so as to contact with a rear surface of the backward projecting peripheral edge by projecting a lower part of the downward dog-legged part under the receiving metal fitting; and a plate spring fixed to a front end lower part of a bracket material and coming into pressure contact with an upper half rear surface of the upward dog-legged part of the wedge. |
