Abstract:
1. A method for displacing a floor table, the method comprising the steps of: a) removing a formwork from the floor table after a concrete floor has hardened and lowering the floor table onto at least one roller means; b) mounting at least one front ligament and at least one rear ligament to corresponding front and rear holders of the floor table when the floor table has been retracted from below the hardened concrete floor; c) withdrawing the floor table, supported on the at least one roller means, from below the hardened concrete floor using a crane, wherein the crane keeps the front ligament tightened at a constant length, thereby ensuring a substantially horizontal orientation of the floor table; d) tightening the rear ligament as soon as the hardened concrete floor no longer projects past the rear holder and subsequently gradually shortening the rear ligament and/or gradually extending the front ligament thereby gradually displacing a relocating unit to a center of gravity of the floor table, wherein shortening and/or extension are controlled to keep the floor table in a substantially horizontal orientation; and e) moving, using the crane, the floor table out of the finished storey for further use as soon as the relocating unit has reached a position above the center of gravity of the floor table such that no load acts on the roller means and disposing the floor table onto the hardened concrete floor to produce a further storey.
