2. Description of the Related Art In laying a beam reinforcing bar, facing sets of work columns, which are conventionally prepared as multi-types having different heights, are firstly set on a ground of a work site at required intervals. Several upper main reinforcements are placed in parallel on a reinforcing bar support bar laid across one set of columns, and a large number of star wraps are hung in a state where they are passed through.
By binding the upper main bar and the star wrap, and then lifting the rebar support bar, replacing the work column with a tall separate product, the support bar is raised to an adjustment height that facilitates assembly work. The lower main bar is inserted into the frame of the star lap, and the lower main bar and the star lap are bound.
