率向上を可能にする。Further, the perforated steel flooring materials are arranged in parallel in the width direction, and a plurality of spacers are arranged between the side surface portions of adjacent perforated steel flooring materials. Are connected by a connecting member passing through the through hole in the side surface portion, so that a stable floor can be formed when a plurality of perforated steel floor materials are arranged side by side in the width direction with a predetermined gap. In addition, the gap enables the adjustment of the width, the ventilation, and the lighting efficiency.
