PURPOSE:To provide a floor construction method executed when an underground structure building frame of a building is constructed by the so-called inversely driving construction method. CONSTITUTION:Excavation of the ground 2 is executed up to a lower level deeper than an under surface of a floor 1 to be constructed, and leveling concrete 3 is placed by a thickness L on an excavation surface, and a ceiling finishing material 4 having a thickness (t) is laid on the leveling concrete 3. Floor concrete 5 is placed on it, and after the floor concrete 5 reveals strength, the leveling concrete 3 is removed together with excavation of the ground 2. Besides the ceiling finishing material 4 laid on the leveling concrete 3 effectively functions as a floor form or an edge cutting material, since a ceiling material driving floor is completed, troublesome form work or the like becomes unnecessary, so that the working efficiency is improved and a construction period is shortened. |
