Abstract
Abstract The method of constructing and elevating a building floor slab which comprises the utilization of a frame in the center of the floor slab to which a plurality of sections, such as four sections, are hinged or flexibly connected and then moving the sections about their connection to the frame into a contracted position in plan view of the slab and then elevating the slab to the desired height and then expanding the slab and positioning it on the framework of the building and then subsequently elevating similar slabs by cables passing through the center frame of the slab as a hoistway to position additional slabs below the uppermost slab. In some cases the top slab may be used as a roof.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
143 words
The method of constructing a building comprising erecting a multi-story building framework having vertical elements to define bays providing along said vertical elements a multiplicity of levels, means resisting horizontal and vertical reactions, forming floor slabs from a plurality of sections, flexibly connecting the sections of each floor slab in angularly adjustable relation whereby said sections can move from open expanded position to contracted position, angularly moving the sections to contracted position, elevating the contracted slab upwardly through vertically aligned bays to the desired position, angularly moving the sections to expanded position and supporting the expanded floor slab on its peripheral edges at its desired level on said means along saId vertical elements, the horizontal dimension of said floor slabs in a planar relationship being greater than the spacing between said means whereby said slab is under compression in its at rest position.

Claim 5
Dependent Claim
21 words
The method of claim 1 wherein the floor slab is formed by hinging a plurality of sections to an open framework.
Claim 6
Dependent Claim
59 words
The method of claim 1 wherein the floor slab is formed by hinging a plurality of slab sections to an open frame located generally in the center of the floor slab plan, using the space enframed by said frame as a hoistway for hoisting means and elevating through said hoistway and locating in place beneath it another floor slab.
