A frame provided extending in the vertical direction of the post frame; a scaffold member attached to the frame; and a connecting member provided on the frame and detachably connected to the post frame. It is characterized by that.

  In the present invention, even if there is no veranda structure or the like near the post frame, the worker's scaffold can be secured around the post frame with the work scaffold unit alone. Moreover, since this work scaffold unit is detachable with respect to the post frame, it can be used at various construction sites where the post frame is installed.

  Further, the frame is provided with a displacement prevention member that abuts on the post frame and prevents the displacement of the frame with respect to the left-right direction of the post frame. The structure provided in a low position may be sufficient.

  In this way, it is possible to prevent the frame from being displaced relative to the left-right direction of the post frame. Therefore, regardless of the shape of the post frame, the work scaffold unit is firmly fixed to the post frame by the position shift prevention member. In addition, since a displacement prevention member is provided at a position lower than the connection member, when the operator gets in, the connection member serves as a fulcrum, and the displacement prevention member serves as an action point. The member is strongly pressed against the post frame.
