CENTRAL CORE FOR A BUILDING

BACKGROUND OF THE INVENTION

(1) Field of the Invention. The present invention relates to the field of building construction and more particularly to the field of prefabricated building construction.

(2) Description of the related art

Currently, houses are built in a standard sequence. The following is a typical sequence. Grading and site preparation

Construction of foundation. Typically premixed concrete is poured or pumped into molds constructed on the site.

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. (l) U.S. Patent 4,447,996

This Patent is directed to prefabricated building structures for use in buildings with multiple units. The building will have modules to accept cubicles that are factory built containing an entire bathroom complete with lavatory, bathtub, water closet, and their associated plumbing, electrical wiring, outlets, in-line exhaust fan and the like. The module likewise could be a complete kitchen with appliance, wiring and the like. The prefabricated module that receives the cubicle can be placed to form the building by means of a crane and if the crane is of sufficient capacity the prefabricated cubicle could be positioned in the module and both installed at the same time. The cubicle will have one wall that is an exterior wall so that at a time to upgrade or repair a fire damaged unit a refurbished or new unit can be brought on site and the old one removed with the aid of rollers so that it can be rolled out to the crane. It would also be possible to change the type of cubicle from for instance kitchen to bathroom or bathroom to kitchen.

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-story residential building, but lower than the total height of a two-story 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 story of a two-story 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-story 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 stories 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. Patent 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 j obsite, 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.

SUMMARY OF THE INVENTION

This invention is a core for a building, which has a cuboid framework. Preferably the framework is made of vertical and horizontal metal beams connected to each other. The core has an exterior wall section and three interior shear wall sections joined together to form a room at least two stories tall. The outsides of the interior wall sections are finished with an interior finish; the outside of the exterior wall section are finished with an exterior finish. Building subsystems are attached inside of the framework. Some of these subsystems are provided with connections for connecting with city services.

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 equipment 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.

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.

The figures from incorporated US Patent Application Serial No. 12/748,751 illustrate aspects of embodiments of the invention pertaining to the building infrastructure incorporated into the completed core. In the embodiment described in US Patent Application Serial No. 12/748,751 , the prefabricated core is constructed as one unit, and is transported to the building site, as a four-sided room including an exterior panel and three interior panels joined together. The embodiment described in the instant application is an improvement of that described in US Patent Application Serial No. 12/748,751. In the embodiment described in the instant application, the prefabricated core 174 is constructed, and may be transported to the building site, as two half-cores 182 186. At the building site, the two half-cores 182 186 are joined together to form a four sided room. Figures 1-45 of application No. 12/748,751 illustrate how the infrastructure components are incorporated into the completed core four-sided room. Figures 1 -25 of the instant application illustrate aspects of prefabri cation of the core 174 in two half-cores 182 186.

Advantages to constructing the core 174 in two half-cores 182 186 include enabling two people to work in parallel on different components, e.g., electrical and plumbing. Additionally, the sizes of the two half-cores 182 186 are designed so that transport of the two half-cores 182 186 to the building site can be accomplished with available transportation without the need for wide load carriage.

In the instant invention some components need to be connected across the midline 178 between the two half-cores 182 186. In these cases, connections are made between a component in the front half-core 182 and the corresponding component in the rear half-core 186 for testing purposes. Then the components are disconnected for transport. Finally, the affected components are reconnected when the two half-cores 182 186 are joined on the building site.

Figures 24 and 25 illustrate the fully assembled, prefabricated core 174 of this invention. While Figures 24 and 25 illustrate a two story core 174, those familiar with the field to which this invention pertains will realize that the core 174, can be one or more stories tall.

The completed core 174 is a room which has one exterior panel 172 and three interior panels 1 10. In embodiments described in this application, the completed core 174 is constructed of two core half-cores 182 186. Each half-core 182 186 of the core 174, described in this application, comprises a three-sided room having three closed sides and one open side. At the job site, the two half-cores 182 186 are placed next to each other open side to open side, with the exterior wall 173 at a location which will become the outside of the house and joined together to form the completed core 174.

Each half-core 182 186 of the core 174 may be constructed on a half-framework 10 26 of vertical 12v and horizontal 12h metal beams. Brackets 22 may be attached at the ends 16 of the horizontal beams 12h. All components are mounted on these half- frameworks 10 26, and the interior panels 1 10 and exterior panel 172 may be attached to the brackets 22. The interior panels 110 are made of a framework of wood or metal studs 210 covered with interior panel facings 226. The interior panel facings 226 may be plywood or particle board or similar material. The exterior wall 173 is likewise made of a framework of wood or metal studs 210 covered with an exterior panel facing 236 and coated with an exterior finish 170. The exterior panel facing 236 is, preferably, a polyvinyl chloride composition, or equivalent.

The half-cores 182 186 of this invention are preferably made prefabricated. They are light and rigid which makes them easy to transport. They are sized to be transported on standard semi-trailers without wide load provisions. It will be understood that some or all of the following items will be installed during prefabrication of the half-cores 182, 186: structural hold downs, platforms 14, an access door 154, an air intake louver 158, a water main connection, a gas main connection, drain pipes 98 and sewer connections, a clothes washer connection 282, a drier connection 306 stove connections 302, a dishwasher connection 294, toilet mechanisms, all faucets 198 and mixing valves, all plumbing and shut off valves, a tankless water heater 106 , an outdoor electric meter 30, a subpanel 34, at least one forced air unit, an air conditioner condenser 162, a return air supply duct 86, a air supply duct 82 , a phone line connection, a television line connection, a punch block , a signal splitter , a modem , a security panel , a fire suppression unit, sprinkler line and stubs, an in-line exhaust fan 54 with inlet and exhaust duct 50 and control switches, a drier vent 150h, a range hood 194 with remote in-line exhaust fan 54, ducting 50 82 86 and electrical wiring, and a core in-line exhaust fan 54 with thermostatic control .

Figure 29 is a flow diagram illustrating the steps of building a house employing a two-piece core 174.

In step 510 and 520, the two half-frameworks 10 26 are built. They are then placed next to each other and separated by a small distance on a level sill 218, step 530. Preferably steps 510 through 530 are done at a site remote from the site where the house will be built but could be done at the building site.

In step 540, the subsystems are installed in each half-framework 10 26. Because components of some subsystems are installed in each half- framework 10 26 it may be necessary to make temporary connections across the gap, step 550.

In step 560, the interior panels 1 10 are attached to the S, E and W sides of the half-frameworks 10 26 and the exterior wall 173 is attached to the N side of the front half- framework 26. The interior panels 1 10 and wall 173 can be attached prior to or after the next step but this the preferred timing.

Subsystems are tested, step 570. After all subsystems pass testing, the temporary connections are disconnected, step 580.

In step 590 the two half-cores 182, 186 are lifted, tilted and laid on separate flatbed trucks. They are then trucked to the building site, step 600, where they are lifted of the trucks and tilted upright.

The foundation may be laid at the building site at any point in the prior steps but it must be laid prior to placing the half-cores 182 186 at the building site, step 605. The half-cores 182, 186 are placed on the foundation abutting each other with the exterior wall 173 at a location on the foundation that will become the exterior of the house.

In steps 630 and 640 the half-cores 182 186 are fastened to each other, the half- frameworks 10 26 are attached to the foundation, and components of subsystems in each half are connected to each other as necessary.

After the core 174 is completed, the building is constructed around the core, wet components (see, for example Figure 25) are installed in the proper locations on the core, and utilities (electrical, plumbing, etc.) are run from the core to wherever they are needed in the house, step 650. After this construction proceeds as follows.

Erection of prefabricated wall panels 1 10 172 for the rest of the house on the foundation. Openings are left between panels 110 172 for placement of doors and windows.

Construction of upper floor(s) and ceiling, including connecting floor and ceiling joists to the ledger boards 132 136 in known fashion.

Installation of windows and doors .

Construction of roof ing 114 on the top 56 of the core 174 and prefabricated wall panels 1 10 172.

Figure 29 is a flow diagram illustrating the steps of building a house employing a one-piece core 174.

In steps 710 and 720, the core framework 8 is built and placed on a level sill 218. Preferably these steps are done at a site remote from the site where the house will be build but could be done at the building site.

The subsystems are installed in the framework at step 730, and tested at step 740

In step 750, the interior panels 1 10 are attached to the S, E and W sides of the frameworks and the exterior wall 173 is attached to the N side. In step 760 the core 174 is lifted and laid on a flatbed truck. It is then trucked to the building site, step 770, where it is lifted of the truck, step 780, and placed on the foundation, step 790

The foundation may be laid at the building site at any point in the prior steps but it must be laid prior to placing the core 174 at the building site, step 705.

The core 174 is placed on the foundation with the exterior wall 173 at a location on the foundation that will become the exterior of the house.

In steps 800 the framework 8 of the completed core 174 is fastened to the foundation.

After the core 174 is installed, the building is constructed around it. Wet components (see, for example Figure 25) are installed in the proper locations on the interior panels, and utilities (electrical, plumbing, etc.) are run from the core 174 to wherever they are needed in the house, step 810. After this construction proceeds as follows.

Erection of prefabricated wall panels 1 10 172 for the rest of the house on the foundation. Openings are left between panels 110 172 for placement of doors and windows.

Construction of upper floor(s) and ceiling, including connecting floor and ceiling joists to the ledger boards 132 136 in known fashion.

Installation of windows and doors .

Construction of roofing 114 on the top 56 of the core 174 and prefabricated wall panels.

ONE OR TWO-PIECE CORE

One embodiment of this invention is a core 174 for a building, which has a rectangular prism or cuboid shape. For the purposes of this disclosure,

"rectangular prism" will be used interchangeably with "cuboid". The dictionary definition of "cuboid" is a "rectangular parallelepiped", which is a box shape. For convenience the sides of the core 174 will be designated throughout this document as N, E, S and W. In no way does this imply the direction in which this invention faces. Preferably the core 174 is built on a framework 8 of vertical 12v and horizontal 12h beams connected to each other as illustrated in Figures 1 and 2. Portions 12p of the horizontal beams 12h protrude past the vertical beams 12v.

Building subsystems are attached inside of the framework 8. Some of these subsystems are provided with connections for connecting with city services, such as water, gas, sewer, phone, cable and electricity.

An interior panel 1 10 is attached to the E, S and W sides and an exterior wall 173 is attached to the N side. For the purposes of this application an interior panel 110 is one that is suitable for installation in the interior of a building and an exterior panel 172 is one that is suitable for installation on the exterior of a building. The major difference between these panels is that the exterior panel 172 is constructed to withstand the elements whereas an interior panel 110 does not have to be. Persons familiar with the art to which this invention pertains will know the difference in such panels.

The framework 8 may be in two halves: a front half-framework 10 and a rear half- framework 26. The front half-framework 10 includes a front E half-side, a front W half-side and the N side and the rear half-framework 26 includes a rear E half- side, a rear W half-side and the S side. The front S side of the front half- framework 10 and the rear N side of the rear half-framework 26 are open.

TWO-PIECE CORE

A second embodiment of this invention is a core 174 for a building which has a cuboid front half-framework 10, and a cuboid rear half-framework 26. The front half-framework 10 has a front top 56a, front E and W half-sides, and front N and S sides, with the front S side being left open. The rear half-framework 26 has a rear top 56b, rear E and W half-sides, and rear N and S sides, with the rear N side being open. Note that the designations N, E, S, and W are for convenience, and do not imply the direction in which the invention faces. Preferably the half- frameworks 10 26 are made of vertical 12v and horizontal beams connected to each other as illustrated in Figures 1 and 2. Portions 12p of the horizontal beams 12h protrude past the vertical beams 12v. Lifting mechanisms 44, comprising a lifting beam 40 and lifting hook 42 are attached to the front top 56a and the rear top 56b. Building subsystems are attached inside the front 10 and rear 26 half-frameworks. Some of these subsystems are provided with connections for connecting with city services, such as water, gas, sewer, phone, cable and electricity.

An interior panel 1 10 is attached to the front E and W half-sides, the rear E and W half-sides, and the rear S side, and an exterior wall 173 is attached to the front N side.

METHOD OF FABRICATING A ONE-PIECE CORE

This invention further describes a method of constructing a core 174 for a building, which includes the steps of: connecting vertical 12v and horizontal 12h beams to form a framework 8 of cuboid shape having a top, and N, E, S and W sides with portions 12p of the horizontal beams 12h protruding past the vertical beams 12v; attaching a lifting mechanism 44 to the top; attaching a number of building subsystems inside of the framework 8 ; some of the subsystems being provided with connections for connecting with city services; attaching an interior panel 1 10 to the E, S and W sides; and attaching an exterior wall 173 to the N side. The method may further include the steps of: pouring a foundation at a building site; constructing the core 174 at a location remote from the building site: lifting the core 174 with the lifting mechanism 44; placing the core 174 on a vehicle; transporting the core 174 to the building site on the vehicle; and placing the core 174 on the foundation so that the exterior wall 173 is at an exterior of the building. METHOD OF FABRICATING A TWO-PIECE CORE

An embodiment of this invention describes a method of constructing a core 174 for a building, which includes the steps of: connecting a set of vertical 12v and horizontal 12h beams to form a front half- framework 10 of cuboid shape, as shown on Figures 1 and with portions 12p of the horizontal beams 12h protruding past the vertical beams 12v; connecting a set of vertical 12v and horizontal 12h beams to form a rear half- framework 26 of cuboid shape, with portions 12p of the horizontal beams 12h protruding past the vertical beams 12v; attaching lifting mechanisms 44 to the tops 56a 56b of the front 10 and rear 26 half-frameworks; attaching building subsystems inside the front 10 and rear 26 half-frameworks 10, 26 some of the subsystems being provided with connections for connecting with city services; components of some subsystems being installed in both half- frameworks 10 26; attaching interior panels 110 to the E and W sides of the front half-framework 10 and the E and W and S sides of the rear half-framework 26; and attaching an exterior wall 173 to the N side of the front half-framework 10.

This produces a front half-core 182 and a rear half-core 186.

This method may further include the steps of: pouring a foundation at a building site; providing a level location remote from the building site; constructing the front 182 and rear 186 half-cores adjacent each other on the level location; testing one or more building subsystems as appropriate; lifting the half-cores 182 186 with their respective lifting mechanisms 44; placing the front half-core 182 on a first vehicle; placing the half-core 186 on a second vehicle; transporting the half-cores 182, 186 to the building site; and placing the half-cores 182, 186 on the foundation with the S wall of the front half- core 182 abutting the N wall of the rear half-core 186 and the exterior panel 72 at the exterior of the building.
