ABSTRACT:
A method and apparatus for raising concrete floor slabs to form a multi-floor structure. Slabs are cast near ground level with apertures cast for well placed columns. The slabs are lifted sequentially, uppermost first, by an air cushion backed up by follower means to hold the slabs safely at any elevation reached. The air cushion is created between the current uppermost slab, the slab below, and the walls of a steel enclosure erected around the stacked slabs and extending upward allowing slabs to travel upward.
