Core and beam suspension system for a building construction and method of construction

A method of constructing a multi-floor building of the kind in which floors are suspended from a central support, said method comprising,

• (a) forming at least one support core with a plurality of vertically spaced openings for individual floor support beams,
• (b) building an upper floor at ground level,
• (c) lifting the floor to the desired height on the support core,
• (d) inserting a floor support beam into an opening in the support core beneath the floor,
• (e) setting the floor on the support beam to support the floor at that level directly from the core and independently of all the other floors of the building,
• (f) repeating steps (b) through (e) to add a selected number of additional floors, and
• including positioning at least one jack rod support beam on top of the support core, connecting jack rods down from the jack rod support beam, lifting the floor to the desired height by jacking the floor up on the jack rods, and
• including forming the support core of concrete by slip forming and taking the jack rods support beam up the core concurrently with the slip forming, and
• wherein the concrete core is a hollow core having two laterally spaced sidewalls and wherein the openings in the core are horizontally aligned in the sidewalls at each floor level and including conveying each support beam by a conveyor beam to a level in the line with a pair of horizontally aligned openings in the sidewalls beneath the floor, inserting the support beam from the conveyor beam through the pair of aligned openings, and then lowering the conveyor beam to the ground level for use with the next floor being built up.
