ABSTRACT:
A floor structure comprises a plurality of steel beams4arranged in parallel, each steel beam4including 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 flange2. The floor structure further includes a displacement preventing spacer interposed between the upper flanges and/or lower flanges of the adjacent steel beams. The 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 beams4so as to inhibit the steel beams4from displacing downward.
