PROBLEM TO BE SOLVED: To simultaneously lift a plurality of unit floors supported in a layered state.SOLUTION: A unit floor lifting device, which supports a plurality of unit floors 1 in a layered state and lifts the supported unit floors 1, includes: receiving girders 40 on each of which the unit floor 1 is mounted; fixed columns 20 which support the plurality of unit floors 1 in a layered state through the receiving girders 40; movable columns 30 which are installed so as to rise and fall, and rise while supporting the plurality of unit floors 1 in a layered state through the receiving girders 40; a plurality of pins 26, 33 which are installed to the fixed columns 20 and the movable columns 30 at vertical intervals; hooks 42 each of which is movably mounted to the receiving girder 40 and displaces between a support position where the receiving girder 40 is supported by the pin 26 and a retreat position where the hook 42 does not vertically overlap with the pin 26; and hooks 44 each of which is movably mounted to the receiving girder 40 and displaces between a support position where the receiving girder 40 is supported by the pin 33 and a retreat position where the hook 44 does not vertically overlap with the pin 33. |
