This invention relates generally to portable housing structures and more specifically relates to self-contained housing kits.
Approximately 40% of humans live within 60 miles of the coast globally, and that number is expected to increase with the trend of growing urban centers. Sea level rise is expected to increase between 0.65 and 1.3 feet by 2050. In addition to added flood risk due to sea level rise, climate change will also increase the risk of fluvial and flash flooding due to more intense rainfall patterns. It is widely recognized that current housing stock in flood prone areas is inadequate and climate change will continue to expand the areas of flood risk. Record rainfall in 2017 from Hurricane Harvey damaged an estimated 136,000 structures, including many that were not in FEMA designated flood zones.
Despite the known present and future risks of flooding, there are a variety of factors that have failed to deliver new flood resilient residential and commercial structures. The cost of traditional elevated housing systems can be a deterrent for their adoption in low-lying flood prone regions, especially in lower income areas.
Additionally, a variety of temporary structures are known in the prior art for use after disasters. For example, it is known for governments to use manufactured housing, tents and “sprung structures” for housing and office structures. These structures suffer from the fact that they provide for living areas typically at ground level or near ground level, which often prevents them from being used on sodden ground or grounds susceptible to flooding. In addition, structures using fabric or thin skins lack robustness and are susceptible to damage or collapse in high winds. There is thus a need in the art for a more robust, yet easily deployable housing system that can be used in flood prone regions and in regions affected by disaster.
Intermodal shipping containers are standardized containers that are transported primarily by ship, train and truck. They are used to move material globally, regionally and locally. The number of existing containers is large and makes them readily available. By report, in 2012, there were over 20 million intermodal shipping containers in the world. They also come in standardized dimensions and include standard castings at the corners for securing them down and interconnection with other containers. The typical container is a rectangular box made from corrugated steel. At one end of the container are doors allowing access to the interior of the container.
Container standards are determined by the International Organization for Standardization (ISO). For example, common container lengths include 20 feet and 40 feet. These sized containers make up some 80% of all shipping containers in existence. For the standard 20-foot container, the published ISO standards are: a) volume—33.1 cubic meters; b) maximum gross weight—30,400 kilograms; c) empty weight—2,200 kilograms; and d) net load—28,200 kilograms. Standard containers are 8 feet wide and 8.5 feet high. The containers also come in taller dimensions (known as “high cube” containers), which measure 9.5 feet high. Given its steel construct, dimensions and required capacity, the intermodal shipping container is a robust and adaptable structure. In particular, intermodal shipping containers make for readily available containers that can house and be used to transport constituent structural parts for a housing system.
The invention overcomes the deficits of prior art self-contained and disaster housing via an inventive housing system and method that utilizes intermodal shipping containers. In contrast to the prior art, the inventive housing system and method provides for robust, self-contained and readily deployable housing. The system and method provide for elevated living quarters and can be used on sodden or flood susceptible terrain. The living quarters can be made ballasted, pillared or both depending on environment.
In one embodiment the invention is directed to a housing system that comprises an intermodal shipping container. The intermodal shipping container has a bottom, a plurality of sidewalls and a top. The intermodal shipping container has contained inside it a plurality of floor-forming panels connectable to form a floor that can be secured directly or indirectly to the top of the intermodal shipping container. Also contained inside the container is a plurality of panels connectable to form an exterior wall around the floor and that can be secured to the floor when the floor-forming panels are secured to the top of the intermodal shipping container. The container also has inside it a plurality of panels connectable to the wall to form a roof. Structural insulated panels (“SIPs”) are preferably used to make the floor-forming panels, wall-forming panels and roof-forming panels. The container preferably includes in its contents a step kit that includes: steps, a ramp or a ladder (collectively referred to herein as “steps”) sized to extend from the bottom of the intermodal shipping container or ground level to the floor when the floor-forming panels are secured to the top of the intermodal shipping container; or materials sufficient to construct such steps.
The described embodiment housing system can include one or more joists interpositionable between and connectable to the floor and the intermodal shipping container. It may also include one or more anchors to secure the intermodal shipping container to a foundation, a footing or to one or more piers. In another version of this embodiment housing system, the container may contain one or more joists interpositionable between and connectable to the intermodal shipping container and the foundation, the footing or the one or more piers.
In a second embodiment of the inventive housing system, the housing system includes a plurality of intermodal shipping containers. Each of the plurality of intermodal shipping containers has a bottom, a plurality of sidewalls and a top. The plurality of intermodal shipping containers has aggregately contained inside them: a) a plurality of floor-forming panels connectable to form a floor that can be secured to the tops of the plurality of intermodal shipping containers; b) a plurality of panels connectable to form an exterior wall around the floor and that can be secured to the floor when the floor-forming panels are secured to the tops of the plurality of intermodal shipping containers; and c) a plurality of panels connectable to the exterior wall to form a roof. The embodiment system preferably includes a step kit so that when finished the embodiment house has steps sized to extend from ground level or the bottom of at least one of the plurality of intermodal shipping containers to the floor when the floor-forming panels are secured to the tops of the plurality of intermodal shipping containers.
Similar to the first embodiment, the second embodiment housing system can include one or more joists interpositionable between and connectable to the floor and one or more of the plurality of intermodal shipping containers. It may also include one or more anchors to secure one or more of the plurality of intermodal shipping containers to a foundation, a footing or to one or more piers. In another version of this embodiment housing system, the plurality of containers may contain one or more joists interpositionable between and connectable to one or more of the plurality of intermodal shipping containers and the foundation, the footing or the one or more piers.
In other embodiments, the invention is directed to methods of using intermodal shipping containers to create a portable housing system.
Embodiments of the present invention include a self-contained housing system contained and erectable upon one intermodal shipping container and a self-contained housing system contained and erectable upon a plurality of intermodal shipping containers. In other embodiments, the invention is directed to methods of using intermodal shipping containers to create a portable housing system.
A first embodiment of a self-contained housing system contained and erectable upon one intermodal shipping container is shown in
The constituent elements of housing system 100 will be further explained.
In the accompanying figures, the inventive system is used to construct a house, designated generally in the drawings with reference number 60 followed by a letter in order to refer to the particular embodiment house shown or under discussion. In this respect,
A multitude of connecting systems may be used to connect floor-forming panels 20 to containers 10. By way of example, as shown in
As shown in
As shown in
The constituent elements of the second embodiment of the inventive housing system 200 will be further explained. Specifically,
Additional details of the features and advantages of the inventive housing system will now be explained. The intact containers supporting a house or work structure may be used as secure storage or to house mechanical or other systems needed for the home or recovery supplies needed in the immediate area of the disaster. SIPs are preferably used to make the floor-forming panels 20, wall-forming panels 21 and roof-forming panels 22. By using SIPs for these constituent components, a rapidly deployable and easily transportable housing system is provided. As shown in
As can be grasped from the images, by virtue of building a house or work structure on top of the intermodal shipping containers, easily-deployable housing can be placed in areas that are sodden from flooding or rain. Second, by virtue of building a house or work structure on top of the intermodal shipping containers, housing can be provided in areas in which further flooding is expected. Ground-based emergency housing solutions, particularly those relying upon fabric, films and wood structural components would not be appropriate for such locales. Moreover, by using intermodal shipping containers to elevate living or work quarters, the inventive housing system includes an easily ballastable container that can provide additional mass and support to any structure. For example, as shown in
Alternatively, the corrugated steel forming the walls of the typical intermodal housing container can be cut out upon installation to create flow paths under a house. The flow would allow water to flow through the container in the event of flooding. The necessity to modify the shipping container after installation will vary based on geographic location, flood type (fluvial vs. coastal) and severity of flood risk.
The present invention is also directed to a first embodiment method of constructing a sheltering structure. The embodiment method includes providing an intermodal shipping container. The intermodal shipping container has a bottom, a plurality of sidewalls and a top and has contained inside it: a plurality of floor-forming panels connectable to form a floor that can be secured to the top of the intermodal shipping container, a plurality of wall-forming panels connectable to form an exterior wall around the floor and that can be secured to the floor when the floor-forming panels are secured to the intermodal shipping container, and a plurality of roof-forming panels connectable to the wall to form a roof. The method further includes: securing to the top of the intermodal shipping container the plurality of floor-forming panels to form a floor on top of the intermodal shipping container; securing to the floor the plurality of wall-forming panels, the wall-forming panels being arranged on the floor so as to create an exterior wall around the floor; and securing to the exterior wall the plurality of roof-forming panels so as to form a roof.
The present invention is also directed to a second embodiment method of constructing a sheltering structure. The embodiment method comprises providing a plurality of intermodal shipping containers. Each of the intermodal shipping containers has a bottom, a plurality of sidewalls and a top. The plurality of intermodal shipping containers has aggregately contained inside them: a plurality of floor-forming panels connectable to form a floor that can be secured to the tops of the plurality of intermodal shipping containers; a plurality of wall-forming panels connectable to form an exterior wall around the floor and that can be secured to the floor when the floor-forming panels are secured to the tops of the plurality of intermodal shipping containers; and a plurality of roof-forming panels connectable to the wall to form a roof. The method further includes: securing to the tops of the intermodal shipping containers the plurality of floor-forming panels to form a floor on the tops of the intermodal shipping containers; securing to the floor the plurality of wall-forming panels, the wall-forming panels being arranged on the floor so as to create an exterior wall around the floor, and securing to the exterior wall the plurality of roof-forming panels so as to form a roof.
While a kit or prefabricated housing modules may conveniently be shipped within the container(s) to the construction site, there may be instances when the complete housing kit may need to be transported in separate shipments. For example, in the event of a bulk order (e.g. multiple kits being delivered to one building site), it may be more convenient and/or economical to ship building panels/modules in bulk manner to maximize the shipping volume within each container. An example would be grouping all interior wall SIPs/modules needed for multiple dwellings within a single container. Based on the specifications of a bulk order, it could be possible to ship all necessary components in fewer (or more) containers than are needed to provide the structural bases for the structures specified within a bulk order. On the other hand, there may be instances where existing unused containers are already present near the building site and only the other building components would be necessary to erect a structure. There also may be instances where additional shipping containers are used to transport materials but not utilized for structure. Accordingly, the invention includes a third method of constructing a sheltering structure. The third embodiment method includes providing: an intermodal shipping container, the intermodal shipping container having a bottom, a plurality of sidewalls and a top; a plurality of floor-forming panels connectable to form a floor that can be secured to the top of the intermodal shipping container; a plurality of wall-forming panels connectable to form an exterior wall around the floor and that can be secured to the floor when the floor-forming panels are secured to the tops of the plurality of intermodal shipping container; and a plurality of roof-forming panels connectable to the wall to form a roof. The embodiment method further includes: securing to the top of the intermodal shipping container the plurality of floor-forming panels to form a floor on top of the intermodal shipping container, securing to the floor the plurality of wall-forming panels, the wall-forming panels being arranged on the floor so as to create an exterior wall around the floor, and securing to the exterior wall the plurality of roof-forming panels so as to form a roof.
A similar method of constructing a sheltering structure may be used utilizing a plurality of intermodal shipping containers. In this respect, a fourth embodiment method comprises providing: a plurality of intermodal shipping containers, each of the intermodal shipping containers having a bottom, a plurality of sidewalls and a top: a plurality of floor-forming panels connectable to form a floor that can be secured to the tops of the plurality of intermodal shipping containers; a plurality of wall-forming panels connectable to form an exterior wall around the floor and that can be secured to the floor when the floor-forming panels are secured to the tops of the plurality of intermodal shipping containers; and a plurality of roof-forming panels connectable to the wall to form a roof. The embodiment method further includes: securing to the tops of the intermodal shipping containers the plurality of floor-forming panels to form a floor on the tops of the intermodal shipping containers; securing to the floor the plurality of wall-forming panels, the wall-forming panels being arranged on the floor so as to create an exterior wall around the floor; and securing to the exterior wall the plurality of roof-forming panels so as to form a roof.
Importantly, the foregoing constituent actions of the described methods need not necessarily be done in the order described and should not be deemed strictly as serial steps. For example, the wall-forming panels may be secured to the floor formed from the floor-forming panels before securing the floor-forming panels or floor to the top of the container. The methods could include the attachment of joists, cross members or a lattice to the top of one container or extending from one container to another. The particular embodiment housing system and methods disclosed above are illustrative and may respectively include other components or steps to enhance the constructed housing structures. The housing structures shown are also merely illustrative of housing structures that can be built utilizing the inventive systems and methods. More ornate or elaborate structures may be constructed using the systems and methods disclosed herein. To better visualize the included drawings, a line may not be present at every joint where panels connect. Panel systems that can be utilized for this invention can be manufactured in a variety of sizes to meet the specific design and structural requirements of each structure.
