いた。2. Description of the Related Art Conventionally, the bar arrangement in the construction of a reinforced concrete building has been performed manually by an operator. In other words, taking a wall arrangement as an example, when a horizontal bar is erected on a vertical bar that has been erected at a predetermined interval, first, the operator must position the horizontal bar at a predetermined pitch each time with a choke or the like. The vertical streaks were marked on each occasion, and then at least two workers temporarily held the horizontal streaks at the marked positions and used the binding line to bind the horizontal streaks to the vertical streaks.
