  2. Description of the Related Art Conventionally, as a working or inspection scaffold attached along a structure such as a building or a bridge pier, one that supports a floor board in a cantilever manner using a bracket for scaffold is often used (for example, Patent Document 1). reference).

Japanese Utility Model Publication No. 6-56328

  In the conventional scaffold as described in Patent Document 1, when the mounting position of the bracket for the scaffold is shifted from a predetermined position, the scaffold cannot be mounted as it is. For this reason, it is necessary to process a bracket and other members at the site, and there is a problem that the work time at the site for attaching the scaffold becomes long and the work cost increases. In particular, in the bridge inspection road, unevenness occurs due to the construction accuracy on the side of the frame to which the scaffold is attached, and it becomes difficult to adjust the attachment of the bracket for the scaffold and the like, and the work time on the site is often prolonged.

  The present invention has been made by paying attention to such a problem, and can easily adjust the mounting position, shorten the work time in the field for mounting the scaffold, and can reduce the work cost. And to provide a scaffold structure.

  To achieve the above object, a scaffold bracket according to the present invention is a scaffold bracket for supporting a floor plate of a scaffold attached along a structure, and has a fixed surface, and the installation of the structure A fixing portion for fixing the fixing surface along the fixing portion, and a support portion that extends in a direction perpendicular to the fixing surface and supports the floor board, and the fixing portion is provided on the left and right sides of the installation portion.
