US 2021/0189722 A1 · PRE-CAST CONCRETE FLOORING SYSTEMS AND METHODS OF USE

Abstract

Various implementations include a corrugated concrete floor system that includes a plurality of elongated pre-cast concrete floor support units disposed in a horizontal arrangement relative to each other for each floor of a building. The concrete floor support units are disposed between floors of a multi-story building. The units define a plurality of supply air plenums and return air plenums that are arranged alternately in the sandwich space between each floor. The supply air plenums are in fluid communication with the building level above them, and the return air plenums are in fluid communication with the building level below them. By having the supply-air plenum and the return-air plenum share the volume occupied by concrete floor support units, the height of the sandwich space is reduced.

Dependent claims

A pre-cast concrete floor support system, comprising:

at least a first elongated floor support unit and a second elongated floor support unit, each elongated floor support unit comprising:
a first wall;
a second wall;
a third wall;
a first web extending between the first wall and the second wall;
and
a second web extending between the first wall and the third wall,
wherein the second and third walls are coplanar and lie in a plane that is parallel and spaced apart from the first wall, the first and second webs are spaced apart from each other, and the first wall and the first and second webs define a channel therebetween;
and
a distal edge of the third wall of the first elongated floor support unit abuts against a distal edge of the second wall of the second elongated floor support unit, wherein the distal edges of the second and third walls are spaced apart from the first and second webs, respectively,
wherein the channel defined by the first wall and the first and second webs of each elongated floor support unit is a first channel and faces a first vertical direction, and a second channel is defined by the third wall and the second web of the first elongated floor support unit and the abutting second wall and the first web of the second elongated floor support unit, the second channel faces a second vertical direction that is opposite from the first vertical direction.
