This description generally relates to modular building units, and specifically to prefabricated, pre-wired, multi-conduit building panel design for modular building units.
On-site installation of electrical conduit, plumbing conduit, and other conduits of construction projects can often delay project completion, which can burden customers with increased costs and negatively impact contractors' reputations. Further, variations in installation practices among construction professionals can reduce quality uniformity across construction projects.
A modular building unit is a panelized system that is composed of prefabricated panels designed for modular building of construction projects, including residential and commercial construction projects. A modular pre-wired building panel design facilitates the standardization of wiring, plumbing, and other conduit installation practices across construction projects. Panels (such as walls or ceilings) are prefabricated with a combination of electrical, network, plumbing, fire alarm, fire sprinkler, low voltage, HVAC, and other components pre-installed (e.g., installed within the panel before the transportation of the panel to a construction site). The panels are coupled during project assembly to form building structures. Prefabricated panels may be customized based on the size and configuration of the modular building unit, customer preferences, construction laws, circuit requirements of individual rooms, and the like.
In some embodiments, a modular building unit may include a combination of prefabricated wall panels, ceiling panels, floor panels, utility wall panels, and breaker panels. Modular building structures may include one or more primary wall panels (or “riser wall”) that include a set of conduits pre-wired/pre-installed within the walls. The set of conduits can include any number of pre-installed conduits, which can be housed in any number of conduit housings. The conduits can be routed from the riser wall to one or more other wall panels or ceiling panels throughout a building structure. A first riser wall within a first floor of a building unit can be located below a second riser wall within a second floor of a building unit, enabling the set of pre-installed conduits within the first riser wall to couple to the set of pre-installed conduits within the second riser wall (e.g., via a conduit coupling in the first riser wall and a reciprocal conduit coupling in the second riser wall), providing conduit access to multiple floors within a structure.
Prefabricated wall panels can include cavities located within the wall panels above a door frame that provide space for the routing of a set of conduits within the wall panel. By reserving the space above the door, there is a guaranteed avenue that can be utilized to route the set of conduits from within the wall to another wall panel, or to allow conduit from a first wall panel to be route to a second wall panel via the above-door cavity within a third wall panel. Some modular building units can include rooms of varying heights within the same floor of the building unit. In such instances, the above-door cavity can be used to route a set of conduits from a ceiling of a first room abutting the wall panel including the above-door cavity into a ceiling of a second room abutting the wall panel via the above-door cavity.
Prefabricated wall panels can include fire sprinkler heads pre-installed within the wall panel. For interior wall panels that abut multiple rooms (e.g., a first room abutting a first surface of the interior wall panel and a second room abutting a second surface of the interior wall panel), the wall panels can include multi-headed fire sprinklers. Each wall panel can include a first pre-installed fire sprinkler conduit that carries water or another fire suppressant running vertically from a top surface or a bottom surface of the wall panel. The first conduit can be coupled to a second pre-installed conduit perpendicular to the first conduit and protruding from each of the first surface and the second surface of the wall panel. Each end of the second conduit can be coupled to a separate sprinkler head (e.g., a first sprinkler head within the first room and a second sprinkler head within the second room). Such a prefabricated wall panel can provide fire sprinkler access to multiple rooms, simplifying the design of a fire sprinkler system and improving the safety of the modular building unit.
The figures depict various example embodiments of the present technology for purposes of illustration only. One skilled in the art will readily recognize from the following description that other alternative embodiments of the structures and methods illustrated herein may be employed without departing from the principles of the technology described herein.
The concepts described herein are generally related to modular construction, a field of construction that, in general, relates to the prefabrication of construction materials at a location other than the construction location. For instance, wall panels, ceiling panels, conduit structures, foundation structures, support structures, frames, and the like can be prefabricated at (for example) a manufacturing location, and then transported to a construction location for assembly. By fabricating materials in advance, modular construction can enable the rapid assembly of prefabricated materials at the construction location, often reducing the total construction time significantly.
As used herein, a “modular building” refers to an outcome of a modular construction project, such as a dwelling structure, an office structure, an apartment complex, a skyrise building, or any other suitable residential, commercial, industrial, or other structure. A modular building may include a number of units, such as apartments, condominiums, offices, and the like. Each modular building can include particular sections, such as rooms, bathrooms, hallways, common areas, and the like. Each module building can include a number of prefabricated components or elements, such as prefabricated wall panels, prefabricated ceiling panels, and the like.
Prefabricated panel components may include a combination of power outlets (e.g., GFCI and AFCI outlets), network outlets (e.g., network ports, controls), plumbing pipes (e.g., cold water, hot water, sewage pipes), and other conduits as described herein. Power outlets may be used for various appliances and electronics of the modular building unit, such as cooktops, dishwashers, garbage disposals, refrigerators, microwaves, range hoods, kitchen and bathroom receptacles, washing machines, dryers, bedroom receptacles, living room receptacles, air conditioners, water heaters, and the like. The modular building unit 100 shown includes several power outlets embedded within a utility wall panel 105, including power outlet 120, a prefabricated exterior wall panel 110 with one power outlet 125, and an interior wall panel 115 without power outlets. However, the location and configuration of components within alternative modular building units may vary.
Prefabricated panels may also include electrical junctions that are connected to the power outlets and/or network outlets via electrical conduits or network lines. The location and number of electrical junctions within each prefabricated panel may vary. For example, electrical junctions may be located at the top or the bottom of the prefabricated wall panels, an electrical junction may be coupled to one or more outlets, prefabricated panels may include multiple electrical junctions, and the like. An electrical junction includes a coupling interface that enables electrical and/or communicative coupling of the corresponding prefabricated panel to a reciprocal electrical junction of an adjacent prefabricated panel of the modular building unit 100. In some embodiments, the electrical junctions are embedded within the prefabricated panels with coupling interfaces at locations on the surface of the prefabricated panels (for instance, along a surface of the prefabricated panels that abuts a surface of another prefabricated panel) such that when a coupling interface of a first prefabricated panel couples to a coupling interface of a second prefabricated panel, neither the coupling interfaces nor the electrical junctions are visible from within the structure. Plumbing pipes may also include coupling interfaces such that the plumping pipes are configured to couple to plumbing pipes in adjacent prefabricated wall panels, water systems, mechanical, electrical, plumbing (MEP) rooms, and the like, during assembly of the modular building unit.
The modular building unit 100 further includes one or more breaker panels. Breaker panels (when coupled to an exterior power source) may provide power outlets electricity through feeder lines of the breaker panel. In some embodiments, electricity flows through the feeder lines directly to the power outlets embedded within a prefabricated wall panel. For example, electricity may flow to the power outlets along utility wall panel 105 directly from a feeder line. In alternative embodiments, electricity flows from the feeder lines through one or more electrical junctions coupled to the power outlets.
The breaker panel may be located on an exterior wall of the modular building unit 100, such as the first breaker panel 130. Alternatively, the breaker panel may be located on an interior wall of the modular building unit 100, such as the second breaker panel 135. In some embodiments, the modular building unit 100 includes more than one breaker panel.
While the prefabricated wall panel 300 shown includes one electrical junction 305 coupled to a single power outlet 310, electrical junctions may be coupled to more than one power outlet. Further, prefabricated wall panels may include additional electrical junctions. Additional electrical junctions may be included based on the circuit requirements of the rooms enclosed by and on each side of the wall panel. For example, a first side of a prefabricated wall panel may be a wall of a bathroom with different and distinct circuit requirements than a kitchen on an opposite side of the wall. Prefabricated wall panels may also include additional electrical junctions coupled to network outlets through network lines, discussed in detail with reference to
During prefabrication, the exterior electrical junctions are electrically coupled to the central electrical junction 415 of the prefabricated ceiling panel 405. The central electrical junction 415 enables the flow of electricity from a breaker panel to the power outlets embedded within the prefabricated wall panels of the modular building unit through the central electrical junction 415 and the exterior electrical junctions. In one embodiment, electricity flows from the breaker panel to the central electrical junction 415 via a loose connector wire 420 configured to be coupled to the breaker panel during assembly. The central electrical junction 415 may then distribute electricity to the exterior junctions of the ceiling panel 405. The exterior junctions of the ceiling panel facilitate the flow of electricity to the power outlets of a prefabricated wall panel through the electrical junctions of the prefabricated wall panel and the electrical conduits connecting them. The central electrical junction 415 can electrically couple to a central electrical junction of an adjacent ceiling panel, enabling a daisy-chain of consecutive adjacent ceiling panels from the breaker panel and through each ceiling panel. In alternative embodiments, exterior and central electrical junctions may be located within prefabricated floor panels of a modular building unit. In these embodiments, electricity flows from the breaker panel, through the prefabricated floor panels to the power outlets of the prefabricated wall panels.
The modular building unit 500 shown includes a first ceiling panel with a first central electrical junction 505. The first central electrical junction 505 is electrically coupled to the breaker panel 130. In some embodiments, a second electrical junction 510 of a second ceiling panel and a third electrical junction 515 of a third ceiling panel are serially coupled to the first central electrical junction 505. In other embodiments, the central electrical junctions may be connected in parallel, or connected in any other suitable configuration.
In some embodiments, the central electrical junction of the ceiling panel adjacent to the utility wall of the modular building unit is electrically coupled to an electrical junction of the utility wall. In other embodiments, as discussed with reference to
In some embodiments, the network outlets are communicatively coupled to a smart home hub that allows users to control settings of the network connectors via one or more control panels and/or through a user device, such as a smart phone, tablet, or computer. For example, control panels may allow users to adjust the temperature of the modular building unit, raise blinds, shut off lights, and the like. The number of control panels may vary based on the size and configuration of the modular building unit. For example, a modular building unit with three rooms may include three control panels.
The modular building unit 700 shown includes a smart home hub 705 that is communicatively coupled to the network outlets. The arrangement of network outlets may vary based on the configuration of the modular building unit, user preferences and habits, and the like. Network outlets may be located on prefabricated exterior wall panels, interior wall panels, ceiling panels, floor panels, etc. Similarly, network outlets may be located on either side of a prefabricated panel. For example, the lighting fixture 710 of the prefabricated exterior wall panel 715 is located on the interior side of the prefabricated panel 715. The prefabricated exterior wall panel 720 includes network connectors on both the interior and exterior sides of the prefabricated panel 720. As shown, the prefabricated exterior wall panel 720 includes a doorbell 725 and light fixture 730 on the exterior side and a control panel 735 and ethernet port 740 on the interior side.
The illustration 800 shows two electrical junctions. The first electrical junction 805 is electrically coupled to the doorbell 725 and to two power outlets, power outlet 810 and power outlet 815 through electrical conduits, e.g., electrical conduit 820. The first electrical junction 805 may provide a standard power voltage (e.g., 110V AC) to the power outlets it is coupled with. The second electrical junction 825 includes a group of connectors that are each connected to a network outlet through a network line. As shown, the second electrical junction 825 includes connectors coupled to a light fixture 730, control panel 735, and an ethernet port 740. The second electrical junction 825 enables data to flow from the network lines to each of the network outlets. The second electrical junction 825 may also enable the flow of electricity (e.g., low voltage electricity) to each of the network outlets. As shown, the second electrical junction 825 includes a dedicated connector for each network outlet. However, in alternative embodiments, a connector of the electrical junction may be coupled to more than one network outlet.
The wall panel 900 illustrated in
The home automation box 1110, after decoding the data signals, can use the data signals to control the utilities within the prefabricated wall panel 1100. The utilities in the prefabricated wall panel 1100 shown include two power outlets, namely power outlet 1115 and power outlet 1120, a doorbell 1125, a light fixture 1130, a control panel 1135, and an ethernet port 1140. In some embodiments, information received from the utilities (such as doorbell signals, light levels, ethernet data, and the like) can be provided back to the home automation box 1110, which can encode the information into data signals for transmission back through the single connector 1105 within the power signals.
By combining data and power signals within a single conduit, the prefabricated wall panel 1100 can include just the single connector 1105. This simplifies manufacturing of the prefabricated wall panel 1100, it simplifies assembly of a structure using the prefabricated wall panel (since connecting the wall panel to other wall panels requires coupling only the single connector 1105 and not multiple connectors), and it centralizes all data and power transmission within the structure. Accordingly, the use of a single connector 1105 can reduce the cost and difficulty of both manufacturing and assembling prefabricated wall panels or structures made of the prefabricated wall panels.
In the embodiment of
The riser wall 1200 includes building fire alarm and unit smoke alarm conduits 1205 within a first riser wall spacing, refrigerant line sets and communication cable conduits 1210 in a second riser wall spacing, ethernet and coaxial conduits 1215 in a third riser wall spacing, fire sprinkler and cold water (“DCW”)/hot water (“DHW”) conduits 1220 in a fourth riser wall spacing, and high voltage conduit 1225 in a fifth riser wall spacing. Although the conduits of the riser wall 1200 are illustrated as being routed vertically through the riser wall, in practice the conduits can be routed horizontally through the riser panel, in any direction through the riser panel, and in any combination of directions.
Although particular conduits are illustrated in the embodiment of
Each conduit within a set of conduits can be coupled to one or more systems, objects, devices, outlets, plugs, interfaces, appliances, or fixtures within a building unit or structure, both within the riser wall 1200 or within another wall, ceiling, or portion of the building unit or structure. For instance, electrical conduits (such as high voltage power conduit) can be coupled to electrical conduits in other walls or ceilings, and in turn to one or more outlets within those walls or ceilings, thereby providing electricity throughout the building unit or structure. In some embodiments, each prefabricated wall within a building unit or structure includes electrical conduit pre-installed within the wall panel, and each wall panel is electrically coupled either directly or via one or more additional wall panels to the riser wall such that electricity is provided from the electrical conduit of the riser wall into and through the electrical conduit within the additional wall panels.
In some embodiments, each wall panel includes an electrical conduit coupling to enable the efficient coupling of electrical conduit throughout a building unit or structure. For instance, each wall panel can include one or more electrical plugs and/or one or more electrical sockets to enable an installer to quickly plug a first wall panel plug into a second wall panel socket, thereby electrically coupling the first wall panel and the second wall panel. In some embodiments, each wall panel includes an electrical conduit couple within a threshold distance of an edge or a corner of the wall panel, thereby reducing or minimizing the amount of conduit required to electrically couple wall panels together.
In some embodiments, communications conduit (such as Ethernet cable, CAT cable, USB cable, low voltage cable, and the like) to be coupled to one or more digital devices, IoT devices, or communications outlets, allowing for the transmission of data via the communications conduit within the building unit or structure. In some embodiments, a fire alarm conduit can couple to a smoke detector, and a fire sprinkler conduit can couple to a fire sprinkler, thereby enabling smoke detected in a first room to cause the fire sprinkler to spray either within the first room and/or within one or more additional rooms within the building unit or structure. In some embodiments, HVAC conduit can couple to a vent, an air conditioning unit, a heater or furnace, or a fan. In some embodiments, plumbing conduit can couple to a sink, a drain, a toilet, a shower, a bathtub, a washer/dryer, a dishwasher, or to any other suitable appliance or object that requires water and/or the removal of waste water.
The arrangement of combination of conduits within the riser wall 1200 of the embodiment of
The riser wall 1200, when installed within a building or other structure, can couple to a second panel (such as another wall panel or a ceiling panel) with reciprocal conduits such that the conduits from the riser wall can couple to the reciprocal conduits of the second panel. As noted herein, coupling conduit together can include physical couplings on a first wall panel and reciprocal physical couplings on a second wall panel (such as network cable plugs and sockets, male and female plumbing pipe fixtures, electrical plugs and sockets, and the like). Accordingly, the conduits routed through the riser wall 1200 prior to installation of the riser wall can be coupled to conduits throughout the building structure (such as conduits pre-installed without other wall panels or ceiling panels) without requiring the manual routing of these conduits throughout the building structure (and instead requiring only the coupling of the pre-installed conduits to each other in some instances).
The prefabricated panels described herein can include any number or combination of conduits, including the example conduits specifically described herein. However, for the sake of simplicity, reference is made in the description of various wall panel embodiments herein to a “set of conduits”. It should be noted that this is not limiting, and that reference to a set of conduits can likewise include any number or combination of conduits.
In one example, the conduit 1310 is plumbing conduit and the conduit 1312 is fire sprinkler conduit. In this example, the conduit coupling 1305 includes plumbing fixtures enabling the plumbing conduit and fire sprinkler conduit to be coupled to reciprocal plumbing fixtures in another wall panel or ceiling panel. Likewise, in this example, the conduit 1320 is digital communications conduit, the conduit 1322 is fire alarm conduit, and the conduit 1324 is electrical conduit. Continuing with this example, the conduit coupling 1315 includes power and communication outlets enabling the digital communications conduit, fire alarm conduit, and electrical conduit to be coupled to reciprocal power and communication outlets in another wall panel or ceiling panel. Finally, in this example, the conduit 1332 is HVAC conduit, and the conduit coupling 1330 is a vent, enabling the HVAC conduit to couple to reciprocal ducting in another wall panel or ceiling panel.
In some embodiments, a first riser wall in a first floor can be located under another riser wall in a second floor above the first floor. In such embodiments, the conduit pre-installed within the first riser wall can be routed up and into the second riser wall, enabling conduit to be routed to multiple floors within a building unit or structure. The conduit can be routed from each riser wall to other walls, systems, outlets, devices, appliances, or fixtures within the corresponding floor.
The set of conduits 1415 can be coupled to a first set of conduits 1418a pre-installed within a first prefabricated ceiling panel 1410a. Likewise, the set of conduits 1415 can be coupled to a second set of conduits 1418b pre-installed within a second prefabricated ceiling panel 1410b. In the embodiment of
In some embodiments, a floor of a building or structure can include one riser wall, while in other embodiments, a floor can include two or more riser walls. For instance, in some embodiments, if the floor of a structure is above a threshold size (e.g., above a threshold footprint, square footage, length, width, or the like), the floor of the structure can include one or more additional riser walls, each including a pre-installed set of conduits for routing within the floor. In some embodiments, if the floor of a structure or building includes multiple housing units, such as the floor of an apartment building or condo building), then each housing unit may include a separate riser wall. In some embodiments, adjacent housing units within a floor may share a riser wall such that the set of conduits pre-installed within the riser wall can be routed within each adjacent housing unit.
In order to assist with installation of prefabricated wall panels and ceiling panels within a structure, and with the coupling of conduits pre-installed within each wall panel and ceiling panel, prefabricated wall panels can include one or more cavities within the wall panel to enable the routing of conduits between the wall panel and one or more additional wall panels or ceiling panels. In certain embodiments, such cavities can be included above door frames within the prefabricated wall panels.
In the embodiment of
The above-door cavity 1520 can be located in a prefabricated wall panel other than a riser wall, such as the wall panel illustrated in
The prefabricated wall panel 1602 includes a door frame 1604a, a top support 1604b, and an above-door cavity 1607 located above the top support. The room 1600a includes a prefabricated ceiling panel 1605a, which couples to the prefabricated wall panel 1602 at a height greater than the door frame. Likewise, the room 1600b includes a prefabricated ceiling panel 1605b, which couples to the prefabricated wall panel 1602 at a height greater than the door frame (and indeed, at a height greater than the ceiling panel 1605a).
A set of conduits 1615a preinstalled within the ceiling panel 1605a is coupled to a fixture 1610a (such as a light fixture). The set of conduits 1615a is routed from the ceiling panel 1605a and into the above-door cavity 1607, where the set of conduits 1615a are coupled to a set of conduits 1615b pre-installed within the wall panel 1602. The set of conduits 1615b are routed vertically through the above-door cavity 1607 and into the ceiling panel 1605b, where the set of conduits 1615b are coupled to a set of conduits 1615c pre-installed within the ceiling panel 1605b. The set of conduits 1615c is coupled to a fixture 1610b. Accordingly, a continuous set of conduits is routed between the fixture 1610a and the fixture 1610b, from the ceiling panel 1605a through the above-door cavity 1607 of the wall panel 1602 and into the ceiling panel 1605b, and is formed by the combined coupled sets of conduits 1615a, 1615b, and 1615c.
As illustrated in the embodiment of
As noted above, the sets of conduits 1615a, 1615b, and 1615c can be coupled via one or more conduit couplings. For instance, the ceiling panel 1605a can include a conduit coupling within a threshold distance of the portion of the ceiling panel 1605a that abuts the wall panel 1602. Likewise, the wall panel 1602 can include a reciprocal conduit coupling that couples to the conduit coupling of the ceiling panel 1605a. The conduit couplings, when coupled, enabling the set of conduits 1610a to couple to the set of conduits 1605b. For example, the conduit couplings can include electrical connectors enabling an electrical conduit to couple to another electrical conduit, can include plumbing conduits enabling pipes to be coupled, or can include networking cable conduits enabling networking cables to be physically or communicatively coupled.
The prefabricated wall panel 1652 includes a door frame 1654a, a top support 1654b, and an above-door cavity 1657 located above the top support. The room 1650a includes a prefabricated ceiling panel 1655a, which couples to the prefabricated wall panel 1652 at a height greater than the door frame. Likewise, the room 1650b includes a prefabricated ceiling panel 1655b, which couples to the prefabricated wall panel 1652 at a height greater than the door frame and equal to the height of the ceiling panel 1655a.
A set of conduits 1665a preinstalled within the ceiling panel 1665a is coupled to a fixture 1660a (such as a light fixture). The set of conduits 1665a is routed from the ceiling panel 1655a and into the above-door cavity 1657, where the set of conduits 1665a are coupled to a set of conduits 1665b pre-installed within the ceiling panel 1655b and routed into the above-door cavity. The set of conduits 1665c is coupled to a fixture 1660b. Accordingly, a continuous set of conduits is routed between the fixture 1660a and the fixture 1660b, from the ceiling panel 1655a through the above-door cavity 1657 of the wall panel 1652 and into the ceiling panel 1655b, and is formed by the combined coupled sets of conduits 1665a and 1665b.
By including above-door cavities for routing conduiting, when the prefabricated wall panels are installed within a building unit or structure, the people installing the prefabricated wall panels have predictable portions of the structure where conduit can be routed without obstacle. Likewise, designers of building units or structures that are creating designs using prefabricated wall panels are able to rely upon the above-door cavities for the purposes of routing conduit when creating their design. Further, above-door cavities can be leveraged to enable the routing of conduit between rooms of different heights. In such instances, without the presence of dedicated space for conduit routing within a wall panel, an installer has to manually route conduit through a portion of the wall panel that may not otherwise be configured for routing conduit within (or that may not otherwise have conduit pre-installed within).
It should be noted that although reference is made herein to above-door cavities, in practice, the principle of including cavities within prefabricated wall panels for the purposes of reserving space within a prefabricated wall panel for routing cable between wall panels and/or ceiling panels is not limited to areas above doors. For instance, prefabricated wall panels can include cavities above or below windows within the prefabricated wall panels, above or below vents, above or below outlets, or at any location within the prefabricated wall panel (e.g., within a reserved space between wall panels supports, at pre-determined distances from a side, top, or bottom of a prefabricated wall panel, at a manufacturer—or designer-selected location, or at any suitable location with the prefabricated wall panel).
The first pipe component is coupled to the second pipe component 1710 via a right-angle coupling. The first pipe component 1705 is perpendicular to the second pipe component 1710. In some embodiments, the first pipe component 11705 is a component of the fire sprinkler mechanism 1700, and the entire fire sprinkler mechanism is installed with a prefabricated wall panel. In other embodiments, the first pipe component 11705 is routed within a different prefabricated wall panel, such as a ceiling panel, and the second pipe component 1710 extends downward into a prefabricated wall panel coupled to the ceiling panel.
The second pipe component 1710 is coupled to the third pipe component 1720 via a “T” coupling. The third pipe component 1720 is perpendicular to the second pipe component 1710. In some embodiments, the entirety of the third pipe component 1720 is embedded within a prefabricated wall panel, while in other embodiments, the third pipe component extends through surfaces of the prefabricated wall panel and into rooms abutting the prefabricated wall panel. In the embodiment of
The multi-head fire sprinkler mechanisms described herein can reduce the overall number of fire sprinkler mechanisms required to provide sprinkler coverage in every room of a building unit or structure, since each can spray into up to two different rooms. Accordingly, in some embodiments, the number of fire sprinkler mechanisms required for a structure, building unit, or floor is less than the number of rooms within the structure, building unit, or floor. In some embodiments, the number of fire sprinkler mechanisms required is equal to half the number of rooms within the structure, building unit, or floor. In some embodiments, the number of fire sprinkler mechanisms required is a number greater than half the number of rooms, but less than the number of rooms within the structure, building unit, or floor.
A first prefabricated ceiling panel 1704a is coupled to the first prefabricated wall panel 1702a. A second prefabricated ceiling panel 1704b is coupled to the first prefabricated wall panel 1702a and the second prefabricated wall panel 1702b. A third prefabricated ceiling panel 1704c is coupled to the second prefabricated wall panel 1702b and the third prefabricated wall panel 1702c. A fourth prefabricated ceiling panel 1704d is coupled to the third prefabricated wall panel 1702c.
A fire sprinkler conduit 1706 is pre-installed within the first prefabricated wall panel 1702a, and is routed vertically through the first prefabricated wall panel 1702a. The first sprinkler conduit 1706 is coupled to a second fire sprinkler conduit 1708 that is pre-installed and routed horizontally within the ceiling panels 1704b and 1704c. The second fire sprinkler conduit 1708 is coupled to a third fire sprinkler conduit 1709 that is pre-installed and route vertically within the third prefabricated wall panel 1702c. Accordingly, the fire sprinkler conduits 1706, 1708, and 1709 form a collective fire sprinkler conduit that is routed through two prefabricated wall panels (1702a and 1702c) that collectively abut each of the four rooms 1700a, 1700b, 1700c, and 1700d.
A first multi-head fire sprinkler mechanism 1710a is coupled to the fire sprinkler conduit 1706 and a second multi-head fire sprinkler mechanism 1710b is coupled to the fire sprinkler 1709. The first multi-head fire sprinkler mechanism 1710a extends through the prefabricated wall panel 1702a and into the room 1700a and the room 1700b. A first sprinkler 1712a is coupled to a first side of the first multi-head fire sprinkler mechanism 1710a within the room 1700a, and a second sprinkler 1712b is coupled to a second side of the first multi-head fire sprinkler mechanism 1710a within the room 1700b. A third sprinkler 1712c is coupled to a first side of the second multi-head fire sprinkler mechanism 1710b within the room 1700c, and a fourth sprinkler 1712d is coupled to a second side of the second multi-head fire sprinkler mechanism 1710b within the room 1700d.
