Title: Prefabricated containerized housing

Description:
TECHNICAL FIELD 
     The present disclosure is directed to prefabricated housing and, more particularly, to a single, self-contained sustainable housing core configured for intermodal containerization and transport with related methods for construction of a complete dwelling and systems, which may utilize unskilled labor to assemble on site. 
     BACKGROUND OF THE INVENTION 
     Prefabricated housing for dwelling is well known. Some prefabricated housing modules were factory built and transported to a local building site via truck trailer. These early housing modules failed when competing with site built homes due to the resultant high costs and/or extreme designs. These high costs and cumbersome transportation methods prevented such prefabricated housing from reaching other markets, making availability within reach of only a limited regional market. 
     More recent attempts have been made to overcome the associated high costs with early prefabrication housing in an effort to compete with conventional homes. These prefabricated housing systems were designed as wide-load truck size sections, which were joined on site. These designs suffered from drawbacks such as the shipping of empty space and the performance of extensive redundant site work to reconnect the modules and their associated components. These attempts also disadvantageously failed to address the issues of very low cost, sustainability and worldwide distribution of housing units for dwelling. 
     These attempts also do not provide a solution to the worldwide challenges of providing a domicile of shelter and safety for those in need of a home and especially in underdeveloped geographies. People living in underdeveloped geographies lack access to safe drinking water, basic sanitation, and have no access to grid electricity. In addition, manufactured housing to date has failed to consolidate demand and as a result are not able to take advantage of high volume mass production to reduce cost. Such limited regional use fails to create the necessary demand in volume to apply high technology solutions to these domicile issues for those in need. As a result, no known prefabricated manufactured housing to date has achieved sustainable, off grid power and water and sanitation in a viable way. 
     Intermodal shipping containers bring goods to every corner of the world. Many cities include shipping ports that have the capability of handling these standard shipping containers. Standards are determined by the International Organization For Standardization (ISO), which is located in Geneva, Switzerland and publishes the International Standards. For example, five common container lengths include 20 foot (ft), 40 ft, 45 ft, 48 ft, and 53 ft. The 20 ft container is the most common length worldwide and the ISO provides International Standards for the 20 foot container. For example, such published International Standards for the 20 ft container include volume (1,169 ft 3 ), maximum gross mass (52,910 lb), empty weight (4,850 lb) and net load (48,060 lb). 
     Containerization is a system of intermodal freight transport using standard ISO containers. Such shipping containers can be transported by ship, rail, truck or air. However, due to the abundant use of these shipping containers, the return and reuse of these shipping containers has become a drawback. 
     Therefore, it would be desirable to overcome the disadvantages and drawbacks of the prior art with a single, self-contained housing core configured for containerization and related methods for construction of a dwelling and systems for intermodal freight transport thereof. Further, it would be desirable if the housing core and related methods and systems for intermodal freight transport provide low cost, sustaining domiciles of shelter and safety for those in need of a house in various geographies for worldwide distribution. It is most desirable that the housing core and related methods and systems of the present disclosure are advantageously employed to provide an affordable home that is self-sustaining, and utilizes renewable energy and conservation techniques such that the home avoids drawing on non-renewable resources. It is contemplated that such a housing core includes internet access. It is further contemplated that the housing core of the present disclosure is easily and efficiently manufactured and assembled. 
     SUMMARY OF THE INVENTION 
     Accordingly, a single, self-contained housing core configured for containerization is disclosed with related methods of construction of a dwelling and systems for intermodal freight transport thereof, which overcome the disadvantages and drawbacks of the prior art. Desirably, the housing core and related methods and systems, provide low cost, sustaining domiciles of shelter and safety for those in need of a home and in various geographies for worldwide distribution. The housing core and related methods and systems may be advantageously employed to provide an affordable home that is self-sustaining, and utilizes renewable energy and conservation techniques such that the home avoids drawing on non-renewable resources or the need to be connected to utility infrastructure. It is envisioned that the housing core has wireless internet access and/or land line internet access. It is further envisioned that the housing core is easily and efficiently manufactured and assembled. 
     It is envisioned that the core includes all the mechanical, electric and hydraulic systems of the dwelling, as well as the spaces and fixtures to use these systems. The core needs no additional work on site for those systems to function. It is contemplated that the core is a rigid, reinforced structure, which provides lateral stability to the construction of the dwelling. This is advantageously enhanced by the construction of a rigid roof using development items (e.g. wood I-beams and panels). This rigid flat plane roof is laterally braced by the core and extends lateral stability to exterior walls. Alternatively, the roof could be a fabric, suspended between the rigid core and columns or other structural elements. 
     It is contemplated that the housing core configured for containerization is a transport mechanism for materials required for the construction of the dwelling. 
     In one particular embodiment, in accordance with the principals of the present disclosure, a single, self-contained housing core configured for containerization is provided. The housing core includes a first section having a floor and a first portion of walls. A second section is connected with the first section to define at least one cavity. The second section includes a ceiling and a second portion of the walls. The second section also includes a reservoir, such as, for example, a water tank. 
     Deployment items such as, for example, a roof membrane and installed components such as, for example, refrigeration units are disposed in the at least one cavity of the first and second sections. Implants are disposed within the first and second sections. The implants may include high pressure laminate floor surfaces, plumbing pipe trees, electric harness and receiver fittings, etc. Incidental or loose items such as flooring, for example, carpet and portland cement, are disposed with the first and second sections. 
     The first and second sections may be injection molded. The sections may also be manufactured by other methods including vacuum forming. The first section may be configured as a lower half and the second section may be configured as an upper half. The first and second sections may be fabricated from plastic, wood, steel and/or aluminum. The first and second sections can be coated with a hard finishing compound so that the wall surfaces are cleanable and sanitary. The first and second sections may include corner and edge reinforcements. The housing core may have a cross-sectional I-beam configuration to provide strength. 
     It is contemplated that the housing core complies with ISO standards for intermodal freight transport. It is further contemplated that the housing core is configured for standard containerization of a 20 ft high cube container and/or stand-alone operation. 
     Alternatively, the housing core includes water conservation components and/or recycling components. Alternatively, the reservoir is configured to collect natural elements. The housing core can include loose items being disposed in the at least one cavity of the first and second sections. The housing core can include installed components disposed with the first and second sections. The deployment items include a septic system. 
     The at least one cavity is configured to support materials for walls. The walls are constructed to enclose at least 1,000 square feet of enclosure. The housing core may be configured for construction having solid walls at its corners. 
     The first section and the second section may be connected to define a plurality of cavities. The deployment items can be disposed with aligned openings of the first and second sections. The housing core may include panels configured to protect the housing core. The panels are removable from the housing core to form a wall extending from the housing core. The housing core is configured for assembly as a dwelling and provides immediate lateral stability of the dwelling. 
     In an alternate embodiment, in accordance with the principles of the present disclosure, a method for intermodal freight transport of a containerized housing core is provided. The method includes the steps of: providing a single, self-contained housing core, the housing core including a first section and a second section; injection molding a first section; implanting components with the first section during injection molding; injection molding a second section; implanting components with the second section during injection molding; joining the first section and the second section, which creates at least one cavity therebetween; disposing deployment items within the at least one cavity; disposing installed items within the at least one cavity; transporting the housing core via intermodal freight transport; installing deployment items with the first and second sections; and constructing a dwelling unit with the housing core. The method may include the step of constructing extension walls with the housing core to construct the dwelling unit. The method may include the step of consolidating deployment items in the cavity, whereby the step of consolidating includes partial installation of the deployment items and expansion of the deployment items during construction of the dwelling unit. The housing core includes a manufactured, affordable dwelling, which utilizes renewable energy and conservation techniques, and can be delivered worldwide. 
     In another alternate embodiment, a single, self-contained dwelling unit configured for containerization is provided. The dwelling unit includes a lower half having a floor and a lower portion of walls. An upper half is joined with the lower half to define a plurality of cavities. The upper half includes a ceiling and an upper portion of the walls. The upper half also includes a reservoir. Deployment items are disposed in the plurality of cavities. Implants are disposed with the lower half and the upper half. Loose items are disposed in the plurality of cavities. The lower half and the upper half are joined in an I-beam configuration. Extension walls are disposed in the plurality of cavities. 
     The housing core is designed to provide the aspects of a shelter in a package that can be deployed by an unskilled worker, or an end user of the housing core. The house core can be a combination of factory built mechanical and electrical systems coupled with local construction of the shell or enclosure. 
     For example, the housing core may include a one kilowatt system, including one hundred square feet of photovoltaic power, as is contemplated, to be built into the housing core&#39;s structure and will produce 1200 to 1600 kilo-watt hours (kwh) of power annually. It is envisioned that such a power supply is sufficient to provide energy for refrigeration, pumps for water management, light and internet capability. The need for battery storage can be minimized by cycling energy use and conservation techniques. Other renewable power sources can be incorporated when appropriate, such as thermal and/or solar in regions where heat is needed, and wind generation. 
     The housing core provides a dwelling, which includes rain harvesting and water management. Even in semi-arid grassland areas, adequate rainfall can be harvested and stored by the components of the housing core to get through dry seasons. A rain harvesting area or water tank of the housing core is contemplated for each unit. For example, the housing core can include a rain harvesting area, which is 28 by 44 feet or about 1200 square feet with primary storage of about 1000 gallons and secondary storage as needed depending on rainfall and frequency. The water management of the housing core may include recycling water, specially designed fixtures, bathing and laundering techniques, etc. Alternatively, sanitary disposal of waste is achieved by specially-designed deployment items such as, for example, septic systems. 
     The dwelling can provide housing for 4 to 8 persons and provide at least 25 gallons of water per day. This can be collected from about 12 inches of rain per year, and this amount can be supplemented by other methods. Purification methods are well known and can be implemented with minimal electric power. 
     The housing core may be configured to provide dwelling for rural areas whereby population densities are low. Alternatively, the housing core may be utilized with areas having densities of 12 housing cores or about 70 people per acre. It is contemplated that the housing core can include 1200 square feet of living space. Thus, each core can house a single family, an extended family or even two families. 
     In one embodiment, the housing core is configured as a one-story structure. The housing core can effectively harvest rainwater and solar energy, and needs no infrastructure. It is envisioned that a plurality of housing cores may be employed in other configurations such as two-story, three-story and/or multiple story structures. In an alternate embodiment, the housing core(s) may be utilized for small schools and medical centers. Walls may be built with indigenous material, which could be customized to fit specific requirements. Multiple cores could be linked for larger structures. 
     Alternatively, each housing core can be constructed with compacted earth foundations and floors, and require no centralized infrastructure. The housing cores can be constructed on platforms. 
     The housing core design utilizes a system of containerization, which is a component for worldwide delivery. This advantageous system eliminates disposal or returning empty space. In one embodiment, the housing core is transported as a 20 ft container and meets ISO standardized dimensions and specifications. It is envisioned that the relatively small size of the housing core, along with its stackable and weatherproof intermodal handling capabilities, allows stockpiling of multiple housing cores at a storage facility. It is further envisioned that a plurality of housing cores, including thousands of units, could be distributed domestically and throughout the world. For example, such housing cores can be shipped by relief agencies or to be received by communities in the process of building. 
     Advantageously, the containerized housing core does not require opening until it reaches its desired transport destination. Once dispatched to a desired location, or shipped to a predetermined geography, all portions and/or components of the containerized housing core are used to complete the housing unit or dwelling. In one embodiment, an outer protective skin of the housing core includes panels, which would be removed at the transport destination. The panels may be used as a roof deck of the housing core upon which a waterproof membrane is disposed. The housing can include reinforced structural corners, employed for shipping and stacking, to form the structure of the housing core. The core provides rigidity and lateral stability for the dwelling, which allows for facile on-site assembly. The housing core configuration provides for no packaging waste, nor any container or portion thereof to return and/or store. Construction and mechanical systems, such as photovoltaic systems, including walls incorporating them, are constructed, assembled and completed prior to shipping and/or transport. 
     Within the containerized housing core, the remaining volume is packed with prefabricated materials for roof span and water harvesting. Windows and doors, also packed with the housing core, are deployed once the housing core is disposed at its desired location and the dwelling including the housing core is site constructed. It is contemplated that there is sufficient remaining space within the housing core, in addition to the deployable construction materials, to include other appropriate items, such as, bicycles, tools (for example, mud brick presses and compaction devices), clothing, sewing machines, bedding, medical items, books, computers and cellular phones, musical instruments and food. It is further contemplated that specialized agencies could supply these items. 
     It is envisioned that the containerized housing core meets the standards of design, and delivers comfort and livability to users of diverse cultures, economic status and geographic location.

     DETAILED DESCRIPTION OF THE INVENTION 
     The exemplary embodiments of the single, self-contained housing core configured for containerization and related methods of construction for dwellings and systems for intermodal freight transport thereof are disclosed and discussed in terms of prefabricated housing and more particularly, in terms of low cost, sustainable dwellings and domiciles of shelter and safety. It is envisioned that the advantages of the present disclosure may be utilized for the benefit of those in need of a home and in various geographies. The housing core and transport system may be employed for domestic, regional and/or worldwide distribution. It is envisioned that the present disclosure may be used with a range of applications including those employing renewable energy and conservation techniques. It is further envisioned that the housing core is constructed to form a dwelling, which is designed to provide a shelter in a package that can be deployed by those at various skill levels including the most basic such as the end user. The housing core may also include components addressing needs such as personal cleanliness, food storage and preparation, and education, and may include water supply, power supply, internet and sanitation. The housing core can be factory built including mechanical and electrical systems, and coupled with the local construction of the shell or exterior walls of the dwelling unit to create a complete dwelling unit. 
     It is also envisioned that the housing core may provide the foundation for a single dwelling unit, combined with other housing core(s) as a plurality of dwelling units and constructed together as a multiple dwelling unit and/or constructed as a plurality of units or plurality of multiple dwelling units to form a community configuration. It is further envisioned that the housing core of the present disclosure may alternatively be used with existing or constructed on site utilities such as appropriate water, sewer and power supply as provided by a local or regional utility and connected as is known to one skilled in the art. 
     The following discussion includes a description of a housing core, related components, assembly of the containerized unit, containerized transport of the housing core, and exemplary methods of constructing dwellings including the housing core in accordance with the principles of the present disclosure. Alternate embodiments are also disclosed. Reference will now be made in detail to the exemplary embodiments of the present disclosure, which are illustrated in the accompanying figures. Turning now to  FIG. 1 , there is illustrated a single, self-contained housing core  10  configured for containerization in accordance with the principles of the present disclosure. 
     The components of the housing core are fabricated from materials suitable for prefabricated housing, such as, for example, wood, compressed particle board, metals, plastics and/or other materials, depending on the particular application and/or preference of the manufacturer and/or end user. Semi-rigid and rigid plastics as well as foam plastics are contemplated for fabrication, as well as resilient materials, such as rubber. The frame, walls, plumbing, circuitry, and interior fixtures of the housing core may be fabricated from those suitable for a dwelling and/or shelter application. One skilled in the art, however, will realize that other materials and fabrication methods suitable for assembly and manufacture, in accordance with the present disclosure, also would be appropriate. 
     Detailed embodiments for the present disclosure are disclosed therein, however, it is to be understood that the described embodiments are merely exemplary of the disclosure, which may be embodied in various forms. Therefore, specific functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present disclosure in virtually any approximately detailed embodiment. 
     Referring to  FIGS. 1-3 , housing core  10  is configured for transport as a 20 foot intermodal container, which is handled and stacked as a standard container pursuant to applicable ISO standards, which are known to those skilled in the art. At the desired location or final building site, the entire container and components of housing core  10  will be used for construction of the dwelling unit. For example, housing core  10  is transported in containerized form having approximate dimensions, 20′×8′×9′6″. It is envisioned that other sized container dimensions, such as 40 ft, 45 ft, 48 ft and 53 ft may be employed including custom configurations. 
     Housing core  10  includes panels  12  used to protect housing core  10  and its components. Panels  12  are configured as an outer cover or protective skin for housing core  10 . Panels  12  are removed at the final building site and reused for construction. For example, panels  12  may be reused to construct roof  86  ( FIG. 5 ) of the dwelling unit for housing core  10 . Panels  12  may be used to construct other portions of the dwelling unit. Panels  12  are rectangular in configuration, however, other shapes are also envisioned such as, circular, triangle, etc. 
     Panels  12  include access cavities  16 , which communicate in between cavity or cavities  14 , discussed in more detail below, of housing core  10 . Cavities  16  are configured for receipt of the forks of a forklift (not shown) or the like. As such, housing core  10  can be easily maneuvered and manipulated for shipping and storage. It is envisioned that housing core  10  may not include cavities  16  or include a single cavity  16 , or multiple cavities  16 . 
     Housing core  10  includes an injection molded first section, such as, for example, a lower half  18 , as shown in  FIG. 2 , including a floor  20  and a first portion, such as, for example, lower portion  22  of walls  24 . It is contemplated that lower half  18  may be formed, alternative to injection molding, by various fabrication methods such as manual construction, machine forming, vacuum forming, etc. Floor  20  may include a platform, poured foundation, etc. 
     Lower half  18  includes a first bathroom  26  with a shower  28 , a toilet  30  and sinks  32 . Lower half  18  also includes a second bathroom  34  with similar components, and a food preparation area  36  with sinks, countertop, etc. It is envisioned that lower half  18  may have various component configurations, such as a single bath, alternate counter design, closets, showers or bathtub arrangement and alternate access openings, and separate toilet rooms. 
     Housing core  10  includes an injection molded second section, such as, for example, an upper half  38 , as shown in  FIG. 3 . Upper half  38  is joined with lower half  18  to define a plurality of cavities  14 . These cavities  14  define space to accommodate disposal of various items, discussed below, as well as rooms, cabinets, fixtures, appliances, etc. of the dwelling unit including housing core  10 . 
     Upper half  38  includes a ceiling  40  and a second portion, such as, for example an upper portion  42  of walls  24  separating the core into two halves. Upper half  38  includes a reservoir, such as, for example, a water tank  44 . It is contemplated that upper half  38  may be formed, alternative to injection molding, by various fabrication methods such as manual construction, machine forming, vacuum forming, etc. It is further contemplated that housing core  10  may be formed as a single structure such that the first section and the second section are connected and subsequent joining of the halves is not required. The first section and the second section may be monolithically formed, integrally connected, etc. It is envisioned that the reservoir may be configured to support other fluids in multiple compartments and/or other materials. 
     Referring to  FIGS. 3A ,  3 B,  3 C and  3 D, the arrangement of cavities disposed with housing core  10 , walls  24  and floor  20  are designed to achieve the maximum strength for each molded half  18 ,  38 . Both upper half  38  and water tank  44  of upper half  38  are reinforced by vertical ribs disposed along housing core  10  in both directions. Housing core  10  includes walls  102  ( FIGS. 2 and 7 ) of the toilet and bath enclosure as well as a longitudinal rib  106  disposed adjacent food preparation area  36 . When halves  18 ,  38  are joined, the resultant section is an I-beam configuration with web  106  such that reinforcing ribs support the top  40  and bottom flanges  20 . The connection between upper half  38  and lower half  18  is proximate to the neutral axis of the structure of housing core  10  and be staggered or offset where the stresses are minimal. Walls  102  create additional reinforcing such as by creating box beam cross sections. 
     The ends of housing core  10  are solid ( FIG. 3A ) as is the center cross section ( FIG. 3C ) and corners  51 , which can be further reinforced, to accommodate the handling and lifting stresses applied to housing core  10  during movement and handling. These stresses distribute through I-beam configuration (106+20+40) ( FIG. 3D ) of the structure of housing core  10 , as well as exterior panel  12  cladding, which is in place when lifting occurs. I-beam configuration (106+20+40) also provides support for internal connections, walking surfaces and attachment points of housing core  10  for reinforcement for day-to-day loads applied to housing core  10  and its components. This configuration also creates lateral stability, which facilitates construction of the completed dwelling. Reinforcement can be incorporated into housing core  10  to accommodate stresses in an efficient manner. 
     Referring to  FIGS. 4 ,  4 A and  5 , beams  78  are used for the structural framing of roof  86 . These beams  78  are placed below ceiling  40  and run the length and the width of housing core  10  through aligned openings  58 . Access through ports  16  allow a forklift type machine to lift housing core  10  utilizing the strength and placement of beams  78  to position it into its final prepared site. 
     Upper half  38  stores a roofing membrane  46  to be deployed out on the deck of roof  86 . Upper half  38  includes intermodal corner fittings  50  and photovoltaic panels  90 , which is installed with the containerized housing core  10  prior to transport. A natural light and ventilation shaft  54  may be disposed with ceiling  40 . Upper half  38  also includes openings  56 , which facilitate alignment of portions  22  and  42  of walls  24 . Openings  58  of upper half  38  facilitate loading and unloading of beams  78  for roof  86 . It is envisioned that upper half  38  may have various component configurations, such as alternate opening disposal, and provide storage for various items. Roof  86  may be constructed from various materials. 
     Deployment items and installed components, as will be discussed in further detail below, are disposed with lower half  18  and upper half  38 . Implants are disposed within lower half  18  and upper half  38  and are included in the molding process. Implants include high pressure laminate floor surfaces, plumbing pipe trees, electrical wire harness, and receiver fittings, etc. Incidental or loose items are also disposed with lower half  18  and upper half  38 , in spaces such as  14 ,  67 ,  67   a,    44  and  82 . 
     Housing core  10  is a system, which facilitates transport and storage of its components. The components are used for the construction of the corresponding dwelling unit including housing core  10 . It is contemplated that components may also be disposed in shower stalls  67 ,  67   a  of baths  26  and  34 , respectively. In its containerized form in preparation for transport, housing core  10  has first bathroom  26  and second bathroom  34 , which define suitable bathing and toilet spaces for use. Each bathroom  26 ,  34  may have natural light and ventilation, as shown in  FIG. 3 . Each bathroom  26 ,  34  may be variously configured and dimensioned with housing core  10 . For example, each bath may be approximately 50 square feet in floor space. It is envisioned that food preparation area  36  has a 13 foot long counter with cabinets and appliances. Water tank  44  and photovoltaic solar array  90  may be built in with ceiling  40 . Water and electric systems along with their fixtures are disposed within housing core  10  and are installed prior to transport. It is envisioned that water tank  44  is a primary water reservoir, however, housing core  10  may include a secondary reservoir, or a plurality of reservoirs. 
     In containerized form in preparation for transport, housing core  10  includes exterior windows and doors  72  disposed within the space and area of cavities  14  defined by first bathroom  26 . It is envisioned that 8-10 windows/doors may be disposed therein. 
     A septic tank  74  is disposed within the space and area of cavities  14  defined by second bathroom  34 . It is envisioned that septic tank  74  is approximately 900 gallons although other sizes are contemplated. A back up battery  52  is stored within housing core  10 . 
     Aligned openings  58  provide access for placement and transport of beams  78 . For example, multiple beams  78 , which are fill length, for example, 19′6″ long, can be stored over or through shower stall  67  and  67   a  and extend the length of housing core  10 . Beams  78  can be accessed for loading and unloading through aligned openings  58 . Beams  78  may be stored at an area just below the ceiling of first bathroom  26  and through second bathroom  34  with access through aligned openings  58  and above windows  72  and tank  74 . Branches  64  extend electric and waste water hook-up to septic tank  74 , and electric to spaces  100 , are also included with core  10 . 
     The advantageous design of the present disclosure does not require installers skilled in the art of electrical or plumbing. If the final site is in a region where heating is required, this can be provided through a separate heating system of housing core  10  such as thermal solar or conventional boilers, which can be included as a loose item. Such loose items can vary in style depending on climate. 
     In another embodiment, a method for intermodal freight transport of the containerized housing core  10  is provided. This method includes the steps of providing housing core  10 , which includes lower half  18  and upper half  38 . The molded shell or lower and upper halves  18 ,  28  of housing core  10  enclose and support the integrated systems for the dwelling structure employing housing core  10 , which are installed prior to transport. 
     The shell of housing core  10  also serves as a structural carrier for other separate and loose components as discussed herein. Lower half  18  and upper half  38  are injection molded as is known to one skilled in the art in a configuration to conform to standard intermodal container dimensions. It is contemplated that housing core  10  may be formed as a single structure. Various components, as discussed herein, are implanted with lower half  18  and upper half  38  during formation of housing core  10 . 
     The lower and upper halves  18 ,  38  are injection molded utilizing a high, (for example, 3 to 6 pound per cubic foot) density foam plastic (for example, Styrofoam) material, which is injected and cured in the mould as is known to one skilled in the art. A wood matrix material and/or recycled waste material may also be used for fabrication of halves  18 ,  38 .
