Abstract
A staircase assembly is installed in a multi-story building, including first and second flights of stairs that are hingably coupled to a landing, and a plurality of vertically-oriented columns coupled to the landing. The staircase assembly is assembled into a first liftable floor plate, and is disposed in a folded arrangement when the liftable floor plate is positioned at an assembly level elevation. The staircase assembly is disposed in an unfolded arrangement when the first liftable floor plate is positioned at a first design level elevation and a second liftable floor plate that is positioned at a second design level elevation below the first liftable floor plate.
Claims19
A staircase assembly disposed in a multi-story building that includes a first liftable floor plate and a second liftable floor plate, the staircase assembly comprising:
- first and second flights of stairs hingably coupled to a landing;
- and
- a plurality of vertically-oriented columns coupled to the landing;
- wherein the staircase assembly is attached to a floor plate frame of the first liftable floor plate;
- wherein the staircase assembly is configured to be disposed in a folded arrangement and an unfolded arrangement;
- wherein, in the folded arrangement, the staircase assembly and the first liftable floor plate are positioned at an assembly level elevation;
- and
- wherein, in the unfolded arrangement, the staircase assembly is disposed between the first liftable floor plate and the second liftable floor plate, the first liftable floor plate is positioned at a first design level elevation, and the second liftable floor plate is positioned at a second design level elevation below the first liftable floor plate.
A liftable floor plate for a multi-story building, comprising:
- a floor plate frame slidably disposed on an external portion of a vertical support core;
- and
- a staircase assembly including first and second flights of stairs, a landing, and a plurality of vertically-oriented columns;
- wherein the staircase assembly is attached to the floor plate frame;
- wherein the first and second flights of stairs are hingably coupled to the landing;
- wherein the plurality of vertically-oriented columns are coupled to the landing;
- wherein the staircase assembly is disposed in a folded arrangement when the liftable floor plate is positioned at an assembly level elevation;
- and
- wherein the staircase assembly is disposed in an unfolded arrangement when the liftable floor plate is positioned at a design level elevation.
A method for assembling a staircase assembly into a multi-story building, comprising:
- fabricating a first liftable floor plate at an assembly level elevation;
- fabricating a staircase assembly including hingably attaching first and second flights of stairs to a landing;
- arranging the staircase assembly in a folded state;
- attaching the staircase assembly to the first liftable floor plate at the assembly level elevation, wherein the staircase assembly is arranged in the folded state;
- lifting the first liftable floor plate to a first design level elevation;
- and
- unfolding the staircase assembly, including attaching a portion of the first flight of stairs to the first liftable floor plate and attaching a portion of the second flight of stairs to a second liftable floor plate, wherein the second liftable floor plate is disposed below the first liftable floor plate.
