Abstract
A floor structure comprises a plurality of steel beams 4 arranged in parallel, each steel beam 4 including a web, an upper flange disposed at an upper end of the web, and a lower flange disposed at a lower end of the web, a floor surface being formed on the upper flange 2. The floor structure further includes displacement preventing spacers interposed between the upper flanges and/or lower flanges of the adjacent steel beams. Each displacement preventing spacer includes a load receiving part which is brought into engagement with the adjacent upper flanges and/or lower flanges to receive an active load incurred by the individual steel beams 4 so as to inhibit the steel beams 4 from displacing downward.
