Abstract

Fabrication of a multi-story building includes fabricating floor plates at or near ground level, and lifting them to a final position on a vertical support core. A method for assembling one of the floor plates assembling a floor plate frame near ground level. Cambers are imparted into framing members based upon expected deflections, and metal decking is installed onto the floor plate frame. A plurality of permanent support points for the floor plate are determined, wherein the floor plate is attachable to the vertical support core at the permanent support points. First pedestals are installed between ground level and the floor plate frame proximal to the permanent support points for the floor plate. Hardenable material is dispersed onto the metal decking of the floor plate frame while the floor plate frame is lifted at the permanent support points.

Dependent claims

A method for assembling a floor plate for a multi-story building, the method comprising:

determining expected loads for the floor plate;
determining expected deflections for cantilevered portions of the floor plate based upon the expected loads;
assembling a floor plate frame, wherein the floor plate frame includes a plurality of framing members disposed on a plurality of girders;
imparting cambers into the plurality of framing members of the floor plate frame based upon the expected deflections;
installing metal decking onto the floor plate frame;
determining a plurality of permanent support points for the floor plate;
installing a plurality of first pedestals between a base and the floor plate frame, wherein the plurality of first pedestals are disposed to support the floor plate frame proximal to the permanent support points;
installing a plurality of secondary pedestals between the base and the floor plate frame, wherein the secondary pedestals are attached to the floor plate frame;
and wherein the secondary pedestals are disposed to oppose upward and downward deflections of the floor plate frame;
controlling vertical heights of the secondary pedestals based upon the cambers of the plurality of the framing members of the floor plate frame;
and
dispersing hardenable material onto the metal decking of the floor plate frame.

wherein the first end of the first cantilevered beam is attached to the first end of the medial beam at a first junction;
wherein the first cantilevered beam and the medial beam define a first camber;
wherein the first end of the second cantilevered beam is attached to the second end of the medial beam at a second junction, wherein the second cantilevered beam and the medial beam define a second camber;
and
wherein the first and second cambers are selected to achieve a flat horizontal surface on an upper planar surface of the floor plate frame;
and
wherein the metal decking is attached to an underside portion of the floor plate frame;
and
wherein the hardenable material is dispersed onto the metal decking.
