Erection of framing on the foundation. Wood and steel are usually used for framing members. Openings are left in the framing for placement of doors and windows.
Installation of windows and doors.
Construction of roofing on top of the framing.
Installation of exterior walls and/or siding.
Installation of rough electrical wiring.
Installation of rough plumbing.
Installation of rough heating, ventilation and air conditioning (HVAC).
Installation of alarm system wiring.
Installation of phone system wiring.
Installation of local area network LAN wiring.
Installation of insulation in exterior walls and attic.
Attachment of drywall to interior of framing.
Installation of underlayment for floors.
Installation of trim
Painting.
Installation of finish electrical, such as switches and lights.
Installation of finish alarm system.
Installation of LAN and phone system jacks and cover plates.
Installation of bathroom and kitchen counters and cabinets
Installation of finish plumbing, such as sinks, toilets and faucets.
Installation of carpet and other flooring.
Installation of HVAC units.
Hookup to water main or well.
Hookup to sewer or septic system
Correction of problems.
Homes are built to the current standards and government codes and with the latest available amenities. But such construction does not allow for adaptability and installation of new technology. For example, demolition and reconstruction are required if the homeowner wishes to upgrade the existing home's layout and fixtures, or they wish to upgrade the infrastructure (plumbing, electrical, communications, etc.). Since the home's infrastructure is so integrated into the superstructure, it is nearly impossible to simply rearrange spaces without also reconfiguring the main systems of the house as well.
Another problem with typical home construction is that it takes a long time. Usually the foundation is poured quickly and the framing is built very fast but after that it takes a long time to for all the subcontractors to install the electrical, plumbing, etc.
A number of inventors have attempted to solve one or other of these problems.

This reference is directed to a compact service core structure. The walls of the prefabricated compact service core structure are higher than the total height of the floor, wall and ceiling structure of an ordinary one-storey residential building, but lower than the total height of a two-storey building of any kind. The height of the walls is large enough to e.g. accommodate the serviced fixtures of complete main floor bathroom, kitchen, and possibly laundry and utility rooms, as well as lower parts of the same rooms of the second storey of a two-storey structure. On the other hand, the height is small enough to make the prefabricated compact service core structure possible to ship on standard low trailers anywhere in the world. The prefabricated compact service core structure allows for factory completion of all major plumbing, heating, ventilation, and electrical work for a two-storey building, and easy on site hook-up to sewer, water, gas and electrical services from the bottom of the prefabricated compact service core structure ventilation and possibly electrical services may be extended above the top of the core through one or more extension service panels. As all portions of the floor of both storeys and high plumbing wall are suspended, pre-manufacturing of the service core in the plan can easily match all custom designed floor heights or deviations from them usually originating from the supply of building lumber of irregular dimensions.
(9) U.S. Pat. No. 5,890,341
This reference is directed to a modular structure consisting of three modular units of approximately the same size, the center module being the primary module containing the mechanical components of the building, with plumbing, air conditioning and heating ducts, and electrical wiring in the slab floor structural foundation and door jambs. The primary module used to transport the entire structure is completed at the factory, requiring no further work at jobsite, with heating and cooling unit, hot water heater, cabinets and appliances, plumbing and light fixtures and accessories installed at the factory in permanent locations. The major exterior walls, slab floor foundation panels, and ceiling/roof panels for all three modules are similarly manufactured in one piece in full width and the length of the building, eliminating joints, speeding assembly and strengthening the components. The major components of the side modules, consisting of the slab floor foundation panels, ceiling/roof panels and the exterior side walls, are all hinged so that they fold to the side and on top of the primary module. Accessories and wall panels and partitions not hinged are placed on top of the primary module for transportation. Two end walls are bolted to the center module during transportation to the site. At the pre-leveled permanent site, the primary module is lowered to the ground and the hinged slab floor foundation panels, which include hinged and folded exterior walls, along with the ceiling/roof panels, are unfolded and permanently fastened in place for that site, but can be refolded if later relocation is needed. The slab floor foundation panels for all three modules are placed directly on the ground or on a pre-built foundation, single or multi-level design. If a pitched roof was ordered, trusses and pre-sized roofing panels transported on top of the primary module are attached to the flat roof of the center module. Two or more of these triple modules can be joined side-to-side or end-to-end or on top of each other, for erection of multiple-unit buildings.
However, none of these inventions allow a house to be built without waiting for installation of services and none of these inventions allow for ease of maintenance or avoidance of damage during remodeling and renovations.
What is needed is a way of allowing a house to be built without waiting for installation of services and which, when built, would be easy to maintain and remodel.
Development of a way to allow houses to be built without waiting for installation of services and which, when built, would be easy to maintain and remodel represents a great improvement in the field of construction and satisfies a long felt need of the contractor and homeowner.

The present invention is a module that will allow a house to be built without waiting for installation of services. This is because the module is prefabricated with all services already built in. Further, this module allows access to all of the services thus allowing for ease of maintenance and avoidance of collateral damage during renovations and remodeling. It will be recognized by those familiar with the art to which this invention pertains that this invention could, alternatively, be built on site.
The module of this invention separates the infrastructure from the superstructure in a way that allows the two buildings to be altered independent of each other. This is done by prefabricating an “Infrastructure Core,” which contains all the plumbing, mechanical and electrical/communications equipent into one central location that serves the entire house and is easily accessible.
A central infrastructure core makes distribution much simpler. Plumbing only needs to go a short distance, making repairs and replacements easier, and electrical and mechanical systems also benefit from the location of the core and are able to radiate out into the home in an efficient manner.
This core serves as: 1. the housing for all the home's mechanical, plumbing and electrical sources, and 2. a major structural support, providing three shear walls to the structure.
This infrastructural core houses the utilities and electronics of the home in such a way that allows the remaining floor plan to be substantially more flexible than traditional floor plans.
The house will preferably be wired with smart technology that will allow the lighting and electrical systems to be remotely observed and controlled. Individual web sites will allow home owners to monitor, control and maintain the health of their house from inside or remotely over the internet.
The core has an inherent effect on the architecture of the house in the following ways. 1. The vertical orientation of the core, designed to maximize efficiency in floor space and materials, lends itself to a multi-story home. 2. Because of the consolidation of infrastructure in the core, there are fewer ducts and wires running through the home, resulting in fewer essential walls and fixed floor planes. 3. By using lower ceiling heights, three floors can be provided in a space that would normally accommodate only two floors in a traditional home.
Balloon framing was chosen as the main method of construction for the wall panels for several reasons: 1. Components can be created off-site, saving time and money while increasing accuracy. 2. Vertically-oriented walls work seamlessly with window systems. 3. They make it easy to run electric and communication wiring up and down.
It is an objective of this invention to provide a central core for a house that includes all the functionality of a modern infrastructural system. Modern infrastructure needs to be upgradeable, interconnected and monitorable. For example a modern infrastructure should provide notification when FAU filters need to be changed, the water filtration needs filter change, a backup battery for the security system or tech rack needs to be changed, etc.
It is an objective of this invention to provide a core that contributes to the structural stability of the house. The shell of the core provides lateral stability and floor/roof support for the rest of the house. It can be either a wood structure or steel structure. It can be made up of either a rigid frame construction with infill panels or it can be stud wall system.
It is an objective of this invention to provide end use plumbing fixtures such as valves, faucets and toilets, already connected to the hot, cold and sewer distribution system. This minimizes plumbing time at the site and yields better and more consistent quality work since it is completed in a more controlled environment.
It is an objective of this invention to provide 90% of the infrastructural distribution (i.e. pipes, ducts and wires) and 100% infrastructural source hardware (i.e. FAUs, condensers, low voltage controls for lighting or security, water filtration system, electrical panels, fire sprinkler riser, ventilation fans, etc.) within a prefabricated core. This minimizes the work, the time, and the need for many of the trades.
It is an objective of this invention to provide a house in which repair, upgrade or maintenance can be easily and readily accomplished. This obviates the need to tear up concrete floors, finished ceilings or finished walls to access a defective solder joint that was leaking. It also obviates the need to cut into bathroom walls to replace worn out shower valves. In this invention all hardware is organized and installed so that it is easily accessible. Any aspect of the infrastructure can be updated, maintained or repaired without touching the finishes. One does not have to open the superstructure or structure to access any aspect of the infrastructure.
It is an objective of this invention to provide the most efficient vertical and horizontal distribution of the infrastructural elements. This invention is crawl space plus attic plus the vertical and horizontal chases and raceways. This invention facilitates the interconnectivity of the modern infrastructural system. For example: the HVAC system needs electricity, hot & cold water, sewer drain and low voltage control; the security system needs electricity, phone and network connection; the water heater needs electricity or gas, ventilation, connection to the water mains and connection to the plumbing fixtures; security cameras need electricity, back up batteries, phone system and access to the network. All of this access and more is provided conveniently and accessibly within the core of this invention.
It is an objective of this invention to provide a complete, sophisticated and ideal infrastructural system to a house while consuming very little time in construction schedule. It is not only that minimizing the construction time saves money. But also the inherent efficiency of the system plus its factory production will make it cost much less than a site built house. Further, since the core of this invention is factory built it is less likely to be built wrongly. The core of this invention will be pretested and thus will be fully functioning at installation. It will be recognized by those familiar with the art to which this invention pertains, that this invention could, alternatively, be built on site.
It is an objective of this invention to provide a core that is sized to be carried on smaller semi trailers without wide load transport provisions. This invention is light and rigid which makes it easy to transport and install. There are no finishes such as tile or paint that would be vulnerable to damage in shipment.
It is an objective of this invention to provide data on water and electricity consumption, and to operate switches, control temperature, control irrigation system, turn the security system on or off, view the security cameras, and move the shades up and down.
It is an objective of this invention to provide consumer benefits because one company is behind the entire infrastructural system. Instead of dealing with multiple subcontractors customers will deal with the manufacturer of this invention.
It is an objective of this invention to provide remote monitoring through the internet of many aspects of the health of the infrastructure through sensors, cameras and internet.
An appreciation of the other aims and objectives of the present invention and an understanding of it may be achieved by referring to the accompanying drawings and description of a preferred embodiment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
While the present invention is described herein with reference to illustrative embodiments for particular applications, it should be understood that the invention is not limited thereto. Those having ordinary skill in the art and access to the teachings provided herein will recognize additional modifications, applications, and embodiments within the scope thereof and additional fields in which the present invention would be of significant utility.
FIGS. 1-5 show structural aspects of the 3 storey core. The core is essentially a room 14 which has one exterior wall segment 18 and three interior wall segments 22, 26, 30. The core is two or more storeys high and built of framing in standard fashion. Preferably the framing is balloon framing (illustrated in almost all of the Figures), in which the studs 34 run from the foundation 38 to the roof (not shown). Balloon framing is stronger and more rigid than platform framing. An alternate type of framing is shown in FIG. 1A. This type of framing has steel corner posts 31 and beams 32 which are connected with very rigid joints or reinforced with cross braces 33. In this case, intermediate studs 34a are not necessary but may be included to frame openings.
Openings 42, 46 are constructed in the framing for the outside wall for an access door and a fresh air louver. One or more spaces 50 are constructed in one or more of the inside walls 22, 26, 30 for a toilet mechanism. Structural hold downs 54 are attached to the core at each corner 58. These hold downs 54 are used to attach the core to the foundation 38 at the construction site.
FIG. 5B is a detail of a structural hold down 54. The hold down 54 is bolted to a stud 34 and to the sill 36 and foundation 38.
Built in to the core are one or more interior platforms 62 for mechanical units such as the HVAC unit. In cores three storey or more in height, a floor supported by joists 66 is located one storey below the top 68.
The outside of the framing is sheathed with panels 70 so that the walls 18, 22, 26, 30 of the core become shear walls, i.e. able to resist lateral loads. To conform to standard building codes, the panels 70 must be structural plywood. Then the outsides 74 of the interior wall segments 22, 26, 30 are finished with an interior finish, preferably with wall board, to match the interior finish of the house and the outside 78 of the exterior wall segment 18 is finished with an exterior finish, for example, stucco or siding to match the exterior finish of the house.
FIG. 5B shows how interior floors of the house are attached to the interior wall segments of the core. Floor joists 82 are attached to a ledger board 85 provided on the outsides 74 of each of the interior segments 22, 26, 30 with joist hangers 84. This is typically done with nails 83. The floor joists 82 will be attached after delivery of the prefabricated core to the site.
FIGS. 6-14 show plumbing, waste and fuel aspect of the core. The main utilities, i.e. water 86 and gas 90, come into the core from outside the building footprint. Preferably these are provided from underground. Connection 94, 98 is made with main shut off valves (not shown) just outside the outside 78 of the exterior wall segment 18. An irrigation line 96 for hose bibs and sprinklers (not shown), branches off the water main 94 just outside the outside wall 18. A sprinkler controller 100 may be installed on one of the walls of the core and connected electrically to each sprinkler circuit.
Sewer connections 102 are provided within the core. The main sewer line 106 from the street comes under the core slab 38 and branches out to three stub outs 110. The branching and stub outs 110 will be done before the slab 38 is poured in a coordinated location that will connect to the sewer lines 114, 118 of the core. When the core is built all 3 main sewer lines 114 will terminate about 6′′ above ground. Once installed the sewer lines 114 will be connected to the stub outs 110. The 6′′ will allow for some adjustment, just in case the core's sewer lines 114 and stub outs 110 are not perfectly aligned.
In the core, the cold water line 122 is connected to a water heater 126, and to shut off valves (not shown) for all cold water appliances such as faucets 130, toilets 134, mixing valves 138, washers 142, etc. The valves will be located just behind the interior walls 22, 26, 30. Piping will run from these shut off valves through the interior walls 22, 26, 30 of the core. Faucets 130, toilets 134 and mixing valves 138 will be attached to the pipes on the outsides of an interior wall section 22, 26, 30. The other appliances will be attached to the piping later. In the core, the gas line 146 is connected to the water heater 126 and gas cocks for appliances such as ranges 150, driers 154, ovens 158, etc, if they are gas powered. Piping will run from these cocks through the interior 22, 26, 30 walls of the core. All such appliances will eventually be located next to the outside 74 of an interior wall 22, 26, 30. In the core, the hot water line 162 from the water heater 126 is connected to shut off valves (not shown) for all hot water using appliances, such as faucets 130, mixing valves 138, washers 142, etc. Again the valves will be located just behind the interior walls 22, 26, 30 and piping will run from these shut off valves through the interior walls 22, 26, 30 of the core. Faucets 130, and mixing valves 138 will be attached to the pipes on the outsides of an interior wall section 22, 26, 30. The other appliances will be attached to the piping later.
The water heater 126 is located within the core. It may be tankless and attached to the inside 166 of one of the wall segments 18, 22, 26, 30 or it may have a tank and may be attached on one of the interior platforms 62. All other appliances are wall mounted and located next to or attached to the exterior of an interior wall segment. The operating mechanism 134 of all toilets, usually the tank and flush valve, is installed in specially provided openings 50 in the interior wall segments 22, 26, 30. Then the bowl 170 is attached to the mechanism 134 on the outside 74 of the interior wall segment 22, 26 or 30. Suitable toilets for this application are available from Duravit AG of Hornberg, Germany. All cold water piping 122 and gas piping 146 are run within the core and only go through the wall 22, 26, 30 just behind the appliance. Sewer pipes (not illustrated) run from the appliances, such as sinks 174, toilets bowls 170 and washers 142 through the wall 22, 26, 30 directly behind the appliance and then are connected via vertical 114 and lateral runs 118 within the core to the main sewer line 106.
Alternatively, in three storey houses, i.e. ones incorporating three storey cores, the third floor may be a bathroom. In this case the walls 18, 22, 26, 30 of the core are finished and the fixtures are attached to the insides 166 of the interior walls 22, 26, 30. The toilet 134, 170 in such a third floor bathroom is also, preferably wall mounted. A floor plan of such a third storey bathroom is shown on FIG. 14A. A more conventional floor mounted toilet could be used, however this would necessitate increased plumbing labor at a later stage in construction of the house.
In either case, when the core is provided prefabricated, all fixtures are attached in their proper locations prior to delivery of the core to the job site. Then it is only necessary to do any final wall finish, such as tile, paint or wallpaper, and attach any necessary trim and the toilet bowls 170.
FIGS. 15-17 show the electrical power aspect of the core. The electric main 190 is provided to the building, preferably underground. The main 190 runs to a meter 194 located on the exterior of the building, preferably on the outside 78 of an exterior wall segment 18 of the core. From here a line 198 runs inside the core to a main electric subpanel 202. Electric circuits 206 are later run from here to all wall outlets in the house.
Lighting could be done with standard high voltage circuits and switches with circuits 206 running from the main electric subpanel. Preferably, however, lighting will be done with internet protocol (IP) switches. Suitable systems are available from Lutron of Coopersburg, Pa. In this case lighting will be done as shown in FIGS. 18-20. A lighting control panel 210 is electrically connected to the main electric subpanel. From here power runs to each light fixture 218 or zone of light fixtures 218 over a switched power line 226 that runs through conduit 230. Also from panel 210 Category 5 (CAT 5) cable, which is the standard cable used for connecting computer networks, or plain twisted pair wiring 214 runs to a low voltage switch 222 for each light 218 or zone of lights 218. The standard RJ45 connectors on the ends of the cable 214 simply plug into the switches 222 and the control panel 210. Twisted pair wiring 214 is connected with connector blocks. Alternatively, the switches may be wireless. Wired or wireless controls 222 can be located wherever desired within the house. Programming of each control 222 is accomplished from the lighting control panel 210. Preferably power line 226 runs through conduit 230. IP lighting systems are complicated. It is not possible to fully describe such systems in this document. For further details one should consult the technical literature issued by Lutron or equivalent companies.
FIGS. 21-23 show air distribution aspects of the core. Preferably, in larger houses there are two forced air units 234, 238 and an air conditioning condenser unit 242 mounted on the platforms 62 inside the core. In smaller houses there would preferably be only one forced air unit 234 and an air conditioning condenser unit 242. All ducting 246, 250 is preinstalled in the core during prefabrication. Supply air and return air stubs 258 run through the interior walls 22, 26, 30 of the core. These are then connected to the supply air and return air ducts in the remainder of the house, after the house has been constructed around the core. Hot air blown out of the air conditioner condenser unit 242 is able to exit the core through the fresh air louver 254. Air flow is indicated by arrows on FIGS. 21 and 23.
FIGS. 24-26 show the optional whole house water filtration aspects of the core. These are designed to remove, sediments, objectionable tastes and odors, organic chemicals, chlorine and dissolved solids from the water delivered by the mains. To accomplish this there may be one or more filters 262; a water softener 266 with backwash tank 268; and reverse osmosis equipment 274 in the incoming water line.
FIGS. 27-29 show the telephone, TV, data and security aspects of the core. Telephone and cable connections may be located on the outside of the exterior wall section 18 of the core. Inside the core are a security panel 290, a phone punch block 286 and a signal splitter 306. The modem (either DSL or cable), server (if desired) and computer (if desired) are mounted in the rack 298. The incoming phone/DSL 282 or cable line 278 connects to the input of the modem. From there the data lines 310 go through a switch and patch panel to specific locations within the house, where computers or other equipment need to be connected to the network. Alternatively or additionally a wireless modem (not shown) may be connected to the switch and mounted within the core. If only a wireless modem is used, data connections 310 to specific locations within the house will be unnecessary. Incoming phone lines 282 are punched down in the punch block and telephone lines 314 run from there to specific locations within the house where telephone equipment is to be located. Low voltage wiring 302 runs from the security panel 290 to switches on doors and windows; interior detectors; and other security devices.
The house may be provided with a central vacuum system. FIGS. 30-32 show the central vacuum aspect of the core. A central vacuum canister 318 is located in the core. Ducts 322 run from the canister to outlets 326 on each floor, on the exterior of the core. An exhaust duct 330 runs from the canister 318 through the exterior wall segment 18, to the exterior of the core.
FIGS. 33-35 show the fire suppression aspect of the Core. Conventional fire suppression systems are used. A main line 334 runs from the water mains 86 to the riser box 338, which is mounted inside the core and electrically connected to the alarm system in conventional fashion. Fire sprinkler lines 342 run from there to stubs 346 passing through the walls 22, 26, 30 of the core. These are then connected to fire sprinkler lines and heads throughout the house after it is constructed around the core.
FIGS. 36-38 show the central exhaust aspect of the core. The bathrooms and laundry room are exhausted by a remote fan 338. Inlet ducting 342 passes through the walls 22, 26, 30 of the core and connects to the fan 338. An exhaust duct 346 runs from this fan 338 to the fresh air louver 254 so the air can be vented outside the core. Control switches 350, electrically connected to the fan are located in each room. A drier vent runs from the rear of the drier through the core and then through an outside wall of the core.
FIGS. 39-41 show discharge of hot air. A wall fan 358 is installed near the top of the fresh air louver 254 to push the air out. A thermostat switch 362, electrically connected to this fan 358, is located on the inside of one of the interior walls 22, 26, 30 of the core. In this way the core is cooled when the temperature rises above a preset level. This helps in cooling the whole house also. In addition the kitchen air vent 366 is connected via ducting 370 to an exhaust fan 374 within the core. This fan 374 is connected to an exhaust duct 378 which vents through the fresh air louver 254.
FIGS. 42-44 show structural aspects of the two storey core. The two storey core is built similarly to the three storey core except there is no third storey, no third storey floor and no third storey bathroom. All other facilities and appliances are installed and attached the same way in the two and three storey cores. By way of example, FIG. 45 shows some plumbing and waste aspects of the two storey core.
This invention is preferably made prefabricated. It is light and rigid which makes it easy to transport. It is sized to be transported on a standard semi-trailer without wide load provisions. It will be understood that the following items will be installed during prefabrication of the core: structural hold downs 54, interior platforms 62, an access door, a fresh air louver 254, a water main connection 94, a gas main connection 98, drain lines 114, 118 and sewer connections 102, a clothes washer connection, a drier connection (including the gas connection 178), stove and oven connections (including the gas connection 182) a dishwasher connection, toilet mechanisms 134, all faucets 130 and mixing valves 138, all plumbing 122, 146, 162 and shut off valves, a water heater 126, an electric mains connection, a breaker box 202, at least one forced air unit 234, an air conditioning condenser 242, a return air duct 246 and stub, a supply air duct 250 and stub 258, a phone line connection, a television line connection, a punch block 286, a signal splitter 294, a modem, a security panel 290, a fire suppression unit 338, sprinkler line 342 and stubs 346, an exhaust fan 338 with inlet 342 and outlet ducting and control switches 350, a drier vent 354, a range hood 336 with remote fan 374, ducting 370, 378 and electrical wiring, and a core exhaust fan 358 with thermostatic control 362.
