Vertical slip form construction system with multi-function platform, and method of constructing a building therewith

A method of assembling a liftable floor plate for a building, wherein the building includes a vertical support core, the method comprising:

• arranging first and second girders in parallel on opposed sides of the vertical support core at ground level, wherein the first and second girders each includes a vertically-oriented web portion and a flange portion, and wherein a plurality of apertures are disposed in the web portions of the first and second girders;
• and
• assembling a plurality of framing members transverse to and supported by the first and second girders, wherein each of the framing members includes a medial beam attached to first and second cantilevered beams, the assembling including:
• inserting a first end of the first cantilevered beam into one of the apertures of the first girder,
• inserting a first end of the second cantilevered beam into one of the apertures of the second girder,
• joining the first end of the first cantilevered beam to a first end of the medial beam at a first junction,
• setting a first camber between the medial beam and the first cantilevered beam,
• securing the first junction of the medial beam and the first cantilevered beam at the first camber;
• joining the first end of the second cantilevered beam to a second end of the medial beam at a second junction,
• setting a second camber between the medial beam and the second cantilevered beam, and
• securing the second junction of the medial beam and the second cantilevered beam at the second camber.

A building, comprising:

• a plurality of floor plates disposed on a vertical support core;
• wherein each of the floor plates includes:
• first and second girders arranged in parallel and configured to be slidably disposed on opposed sides of the vertical support core, wherein the first and second girders each includes a web portion and a flange portion, and wherein a plurality of apertures are disposed in the web portions of the first and second girders;
• and
• a plurality of framing members, wherein each of the framing members includes a medial beam attached to first and second cantilevered beams, and wherein each framing member is arranged transverse to the first and second girders and supported by the first and the second girders;
• wherein each of the first and second cantilevered beams has a defined cross-sectional shape;
• wherein each of the apertures disposed in the web portions of the first and second girders has a cross-sectional shape corresponding to the defined cross-sectional shape of the first and second cantilevered beams of the framing members;
• wherein each of the medial beams of each of the framing members is disposed between the first and second girders;
• wherein each of the first cantilevered beams includes a first end and a second end;
• wherein each of the second cantilevered beams includes a first end and a second end;
• wherein the first end of each of the first cantilevered beams is threaded through one of the apertures of the first girder and joined to the first end of the respective medial beam at a first junction, wherein the first cantilevered beam and the medial beam define a first camber;
• wherein the first end of each of the second cantilevered beams is threaded through a corresponding one of the apertures of the second girder and joined to the second end of the respective 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 surface of the floor plate when the floor plate is fixedly attached to the vertical support core.
