Slab unit, slab base construction method, and floor construction method

摘要

To provide a floor slab unit capable of stably hanging without setting hanging hooks.SOLUTION: A deck plate 1 with reinforcing steel trusses in which a plurality of reinforcing steel trusses 11 are juxtaposed on the upper surface of a metallic substrate 10 are arranged in a direction perpendicular to the longitudinal direction of the reinforcing steel truss 11 so that the substrate 10 is continuous In the assembled slab unit 3, a metal bar 4 is disposed at a position line-symmetrical with respect to the center line c of the slab unit 3 along the direction in which the substrate 10 is continuous, and each bar 4 Passes under the upper end streak 13 of each reinforcing steel truss 11 and is fixed to the upper end streak 13 at the intersecting position with the upper end streak 13.(FIG.
