Abstract

PURPOSE:To automatically and positively incorporate an H-shape steel of an optional size by providing a pushing-up child truck on which a pushing-up link- arm piece capable of being freely erected and fallen is journalled so as to be set to a specified push-up position, in an alignment parent truck so that it can freely move laterally. CONSTITUTION:A dog 3C pushes and advances the flange of a left H-shape steel 20a, and H-shape steels slide on a skid 12 all together. The pushing-up projection 9a of a pushing-up link-arm piece 9 faces a position situated eccentrically from a center line of the web of a central H-shape steel 20b out of three H-shape steels to the left. When the left half of the flange-underside of the H-shape steel 20b is pushed up, the H-shape steel 20b is tilted to the right to produce a gap S between the flange-underside and the skid 12-surface. Further, when the left side of the H-shape steel 20a is pushed and advanced by the dog 3c, the lower flange of the H-shape steel 20a slides into the gap S. Finally, when the pushing-up projection is retracted below the skid 12-surface, the upper and lower flanges of the central H-shape steel overlap the flange surfaces of the right and left H-shape steels.
