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 (17)

1. A modular building unit comprising:

a first prefabricated wall panel comprising a front surface and a rear surface separated by a plurality of supports, the first prefabricated wall panel comprising a first set of conduits pre-installed within the first prefabricated wall panel;

a door frame within the first prefabricated wall panel producing an opening within the first prefabricated wall panel and comprising a first side support, a second side support, and a top support coupled to the first side support and the second side support;

a cavity within the first prefabricated wall panel located between the first side support and the second side support and above the top support of the door frame, wherein the cavity is below a top edge of the first prefabricated wall panel and between the front surface and the rear surface of the first prefabricated wall panel; and

a second prefabricated wall panel physically coupled to the first prefabricated wall panel, the second prefabricated wall panel comprising a second set of conduits pre-installed within the second prefabricated wall panel;

wherein the first set of conduits embedded within the first prefabricated wall panel is routed vertically and adjacent to a portion of the first side support of the door frame and horizontally into the cavity above the door frame, is connected to a conduit coupling within the cavity above the door frame, and is routed vertically from the cavity above the door frame, and wherein the conduit coupling is coupled to a reciprocal conduit coupling connected to the second set of conduits.

2. The modular building unit of claim 1 , wherein the first prefabricated wall panel abuts a first room and a second room of the modular building unit, and wherein the conduit coupling couples to the reciprocal conduit coupling via the cavity of the first prefabricated wall panel.

3. The modular building unit of claim 1 , wherein the first prefabricated wall panel abuts a first room and a second room of the modular building unit, wherein a height of a first ceiling of the first room differs from a height of a second ceiling of the second room, and wherein the second prefabricated wall panel comprises a ceiling panel of the second room.

4. The modular building unit of claim 3 , wherein the first set of conduits is routed through the cavity of the first prefabricated wall panel by a distance equal to or greater than a difference between the height of the first ceiling and the height of the second ceiling.

5. The modular building unit of claim 1 , wherein the second prefabricated wall panel comprises a prefabricated ceiling panel.

6. The modular building unit of claim 1 , further comprising a third prefabricated wall panel comprising a second door frame and a second cavity within the third prefabricated wall panel above the second door frame, and wherein a third set of conduits is additionally routed into the second cavity of the third prefabricated wall panel.

7. The modular building unit of claim 6 , wherein the third prefabricated wall panel is coupled to the first prefabricated wall panel such that the conduit coupling of the first prefabricated wall panel is coupled to a second reciprocal conduit coupling of the third prefabricated wall panel.

8. The modular building unit of claim 7 , wherein the first set of conduits is additionally coupled to the third set of conduits.

9. The modular building unit of claim 6 , wherein the third prefabricated wall panel is not directly coupled to the first prefabricated wall panel, and wherein the second set of conduits is coupled to the third set of conduits the second cavity of the third prefabricated wall panel.

10. The modular building unit of claim 1 , wherein the second prefabricated wall panel comprises a wall panel located above the first prefabricated wall panel.

11. The modular building unit of claim 1 , wherein the first set of conduits include one or more of: an HVAC conduit, an electrical conduit, a plumbing conduit, a fire alarm conduit, a fire sprinkler conduit, and a digital communications conduit.

12. The modular building unit of claim 1 , wherein the second side support is adjacent to an external support of the plurality of supports.
