Abstract

Prefabricated wall panels simplify the constructive of building units and other structures. The prefabricated wall panels can include a set of conduits pre-installed within the wall panels that enable simplified installation and conduit routing within a building unit or structure. The set of conduits can include electrical conduit, plumbing conduit, HVAC conduit, networking conduit, fire alarm conduit, and fire sprinkler conduit. The prefabricated wall panels can include above-door cavities to assist with structure design and coupling conduits between prefabricated panels. The prefabricated panels can additionally include dual-headed fire sprinklers that enable one fire sprinkler conduit to spray into multiple rooms, reducing the overall number of fire sprinkler conduits required within a structure.

Claims (26)

1. A modular building unit comprising:

a plurality of prefabricated panels comprising wall panels and ceiling panels coupled to form a first room in a first story of the modular building unit and a second room at least partially above the first room in a second story of the modular building unit,

wherein a first wall panel comprises:

a first surface and a second surface,

a first set of conduits embedded within the first wall panel of the wall panels, the first set of conduits comprising first HVAC conduit, first electrical conduit, first plumbing conduit, first fire alarm conduit, first fire sprinkler conduit, and first digital communications conduit,

a plurality of first supports separating the first surface from the second surface and separating at least one conduit from another conduit in the first set of conduits, a first conduit coupling embedded within the first wall panel within a threshold distance of a top of the first wall panel, wherein the first conduit coupling is configured to reciprocally couple to a second conduit coupling embedded within a ceiling panel such that the first set of conduits extends into the ceiling panel via the first conduit coupling and the second conduit coupling;

wherein a second wall panel comprises:

a third surface and a fourth surface,

a second set of conduits embedded within the second wall panel of the wall panels, the second set of conduits comprising second HVAC conduit, second electrical conduit, second plumbing conduit, second fire alarm conduit, second fire sprinkler conduit, and second digital communications conduit,

a plurality of second supports separating the third surface from the fourth surface and separating at least one conduit from another conduit in the second set of conduits;

wherein the second wall panel is configured to be coupled immediately or within the threshold distance above the first wall panel, and, the first set of conduits at a top of the first wall panel is configured to be coupled to the second set of conduits at a bottom of the second wall panel such that the first HVAC conduit is configured to be coupled to the second HVAC conduit, the first electrical conduit is configured to be coupled to the second electrical conduit, the first plumbing conduit is configured to be coupled to the second plumbing conduit, the first fire alarm conduit is configured to be coupled to the second fire alarm conduit, the first fire sprinkler conduit is configured to be coupled to the second fire sprinkler conduit, and the first digital communications conduit is configured to be coupled to the second digital communications conduit;

a set of electrical couplings embedded within each of the wall panels forming the first room enabling each wall panel forming the first room to be electrically coupled to the first or second set of conduits of the first or second wall panels directly or through one or more adjacent wall panels;

a set of digital devices embedded within one or more of the prefabricated panels forming the first room each communicatively coupled to the first or second set of conduits of the first or second wall panels;

a fire sprinkler embedded within at least one of the prefabricated panels forming the first room and coupled to the first or second set of conduits of the first or second wall panels; and

a fire alarm embedded within at least one of the prefabricated panels forming the first room and coupled to the first or second set of conduits of the first or second wall panels.

2. The modular building unit of claim 1 , wherein each wall panel forming the first room includes at least one electrical coupling of the set of electrical couplings and an embedded electrical conduit electrically coupled to at least one electrical coupling such that embedded electrical conduit is electrically coupled to the electrical conduit of the first wall panel via the at least one electrical coupling.

3. The modular building unit of claim 2 , wherein the embedded electrical conduit within a wall panel further electrically couples to a power outlet within the wall panel.

4. The modular building unit of claim 1 , wherein each electric coupling is within a threshold distance of an edge of a wall panel.

5. The modular building unit of claim 1 , wherein each electric coupling is within a threshold distance of a corner of a wall panel.

6. The modular building unit of claim 1 , wherein the first set of conduits runs vertically within the first wall panel.

7. The modular building unit of claim 1 , wherein the set of digital devices includes one or more of: a computing system, a thermostat, an IOT device, a light switch, a low voltage device, and a digital wall port.

8. The modular building unit of claim 1 , wherein the first digital communications conduit comprises one or more of network cable and a low voltage line.

9. The modular building unit of claim 1 , wherein at least one of the prefabricated panels includes one or more of a vent, an air outlet, an air conditioning unit, and a fan coil unit coupled to the first HVAC conduit, and wherein the first HVAC conduit comprises one or more of: a heated air duct, a cooled air duct, a ventilation duct, a heated refrigerant line, a cooled refrigerant line, and a condensation line.

10. The modular building unit of claim 1 , wherein at least one wall panel includes embedded plumbing conduit and a plumbing fixture coupled to the first plumbing conduit of the first wall panel via the embedded plumbing conduit.

11. The modular building unit of claim 1 , wherein the first plumbing conduit includes one or more of a hot water pipe, a cold water pipe, and a waste water pipe.

12. The modular building unit of claim 1 , wherein the first fire sprinkler conduit enables a flow of water or a fire suppressant.
