Abstract

In general, one aspect disclosed features a concrete-fillable prefabricated cartridge for constructing a structural concrete building, the concrete-fillable prefabricated cartridge comprising: an inner wall frame; a removable form attached to an outer portion of the inner wall frame such that liquid concrete may be poured into a cavity defined by the inner wall frame and the removable form; and one or more reinforcement bars disposed within the concrete-fillable form.

Claims (43)

1 . A process of constructing a structural concrete building using one or more concrete-fillable prefabricated cartridges, the process comprising:

providing a concrete-fillable prefabricated cartridge comprising:

an inner wall frame,

a first removable form attached to an outer portion of the inner wall frame such that liquid concrete may be poured into a cavity defined by the inner wall frame and the first removable form, and

one or more reinforcement bars disposed within the cavity of the concrete-fillable prefabricated cartridge, wherein the one or more reinforcement bars are one or more first reinforcement bars;

placing the concrete-fillable prefabricated cartridge upon a slab foundation;

filling the concrete-fillable prefabricated cartridge with liquid concrete;

allowing the liquid concrete to cure;

removing the first removable form;

providing a concrete-fillable prefabricated panelized wall cartridge comprising:

a panelized wall frame,

a second removable form attached to an outer portion of the panelized wall frame such that liquid concrete may be poured into a wall cartridge cavity defined by the panelized wall frame and the second removable form, and

one or more second reinforcement bars disposed within the cavity of the concrete-fillable prefabricated cartridge;

placing the concrete-fillable prefabricated panelized wall cartridge upon the slab foundation;

attaching the concrete-fillable prefabricated panelized wall cartridge to the slab foundation;

filling the concrete-fillable prefabricated panelized wall cartridge with liquid concrete;

allowing the liquid concrete to cure in the concrete-fillable prefabricated panelized wall cartridge; and

removing the second removable form.

2 . The process of claim 1 , wherein:

the concrete-fillable prefabricated cartridge further comprises:

an interior building component attached to an inner portion of the inner wall frame, and

one or more building systems disposed within the inner wall frame and connected to the interior building component; and

the process further comprises: connecting the one or more building systems to one or more corresponding external building systems.

3 . The process of claim 1 , further comprising:

attaching the concrete-fillable prefabricated cartridge to the slab foundation.

4 . The process of claim 1 , wherein attaching the concrete-fillable prefabricated cartridge to the slab foundation comprises:

placing rebar into the concrete-fillable prefabricated cartridge; and

connecting the one or more reinforcement bars disposed within the cavity to an anchor bolt or rebar set into the slab foundation before filling the concrete-fillable prefabricated cartridge with liquid concrete.

5 . The process of claim 1 , wherein the concrete-fillable prefabricated cartridge further is a first concrete-fillable prefabricated cartridge, the process further comprising:

attaching the first concrete-fillable prefabricated cartridge to a second concrete-fillable prefabricated cartridge.

6 . The process of claim 1 , wherein the concrete-fillable prefabricated cartridge further is a first concrete-fillable prefabricated cartridge, the process further comprising:

providing a lintel formwork and a second concrete-fillable prefabricated cartridge;

attaching the lintel formwork between the first concrete-fillable prefabricated cartridge to the second concrete-fillable prefabricated cartridge;

filling the lintel formwork with liquid concrete;

allowing the liquid concrete to cure; and

removing the lintel formwork.

7 . The process of claim 1 , further comprising:

providing a roof structure; and

attaching the roof structure to the concrete-fillable prefabricated cartridge.

8 . The process of claim 7 , wherein attaching the roof structure to the concrete-fillable prefabricated cartridge comprises:

setting an anchor bolt into the liquid concrete;

allowing the liquid concrete to cure; and

attaching the roof structure to the anchor bolt after the allowing the liquid concrete to cure.
