The present invention relates to housing shelter structures that can be rapidly and easily assembled for persons in need after a natural or man-made disaster, and which can also be easily and quickly disassembled when their emergency use is completed, so that they can be transported quickly to another nearby location at the disaster site, or be transported to a distant location after a different natural or man-made disaster has occurred elsewhere.
T-shaped joists have been used previously in housing structures to support flat wall panels, which walls may be between two spaced apart T-shaped joists, where the T shaped joists have a flat base located on the exterior of the walls of the structure, and the protruding mid flange of each of the T shaped joists extends inward into the interior of the structure.
One problem with using T shaped joists with an interior extending/protruding mid flange is that the bottom of the wall panel held between the T-shaped joists is positioned flush with the floor of the interior of the structure. Therefore, rainwater or flood water can seep in at the bottom of the joists and the bottom of the wall panels right into the level of the interior floor of the structure. Often such structures that may be built as replacement housing have to be installed at an elevated location being several feet off the ground, to avoid ground level seepage.
Some prior art patents for portable housing include U.S. Pat. Nos. 3,069,224 to Bigelow and 5,070,667 to Bigelow, Republic of Korea patent application number KR100978578 B1 and French Patent Number 482,354 of Société Civile D'Architecture Industrielle. Bigelow teaches the use of an inwardly extending T-shape, as shown in
In keeping with the following objects and others which may become apparent, the present invention is for quick and easily deployable and disassemblable housing shelters for disaster sites and other areas where there is a need for rapidly deployable housing structures for people in need.
The herein disclosed house structures can be rapidly deployed to, and be quickly assembled on location at, a disaster area (flood, earthquake, fire, hurricane, Covid etc.), and which, on the other hand, can also be rapidly disassembled, after the temporary shelter is no longer needed. A single housing shelter as disclosed herein may constitute a bundled up set of longitudinally extending T-shaped upright posts, which support nested in spaces between corners of base legs and outwardly extending base web unit the vertical wall panels, where the uprights can also function as longitudinally extending T-shaped roof rafters, also for nesting the same panels as roof panels.
All of the components of the housing shelter structure can be taken apart and reassembled a multitude of times, particularly because no nails are used, which would otherwise cause degradation of the components when being hammered for disassembly. The nails also leave indelible marks. All of the holes for the screws are also predrilled so as not to rip apart the wall panels, and cause irreparable damage when the unit may be destined for immediate reassembly at another location of critical need.
Basically, the T-shaped upright posts are set with protruding lengthwise extending buttressing web leg sections, extending out perpendicular to the lengthwise extending surface of the base legs, forming generally squared-off, concave receding areas between two of the perpendicular protruding lengthwise extending web leg sections. As such, two adjacent upright posts, spaced about 30 inches apart, may be provided to “nest” two or three inch thick foam risen filled panels, having rectangular shapes of about thirty inches in width and eight feet in length, so that the wall panels nest in the squared off, concave receding areas between the perpendicularly and outwardly extending lengthwise buttressing web leg sections of the eight foot T-shaped uprights.
The roof of the housing shelter structure forms a gable with a lengthwise extending peak, formed by pairs of angularly extending roof rafters, which may have the same dimensions as the upright posts, except that the roof rafters have corresponding angular notches accepting the corresponding vertically extending T-shaped uprights, to maintain the T-shaped roof rafters in place above the T-shaped uprights, while also assuring a vertical plumb line of the vertical walls of the housing structure.
Preferably the angle of the roof gable has a 12 over 6 horizontal to vertical ratio.
The tops of the T-shaped uprights fit into the angularly cut notches of the T-shaped roof rafters, to securely accommodate the angularly placed T-shaped roof rafters. These angled notches are provided in the lower end of the T-shaped roof rafters, which nest the roof panels therebetween. The distal one-foot lengths of the nested roof panels form collectively the roof overhang tails of the deployable and disassemblable housing shelter structure.
The eight-foot by thirty-inch wall (and roof) panels also nest between the aforementioned pairs of the upright T shaped posts which act as roof rafters. Like the upright posts, the roof rafters are also T-shaped in cross section, with a base leg portion and a perpendicularly and outwardly extending buttressing web leg portion. They connect angularly at a peak, forming a truss, but not a truss that can't be disassembled. The same wall panels become roof panels, where seven feet of each roof panel slidably nests between perpendicular buttressing web leg sections of adjacent rafters (T-shaped also), so that the extra one foot remaining of the 8-foot panels form the overhang tails of the roof. Therefore, the sets of two joining roof rafters having the nested panels therebetween form the room where seven feet of each panel forms the sloped roof and the remaining one foot at the distal ends of the panels forms the roof overhang tail for each panel of the roof.
Windows and a door are pre-built into panels. For safety, one of the windows is preferably an “egress ” window.
These rapidly deployable and disassemblable housing structure shelters are assembled on site, and can be disassembled after their use is complete, and then be deployed to another disaster location. The components are built in a factory setting, so that all the tolerances can be maintained, and so that every part is identical to the next part. The parts for different houses can be interchanged because the components are identical. Unlike conventional SIP panels (“Structurally Insulated Panels”) which require all kinds of adhesives, fmishings and coatings, the panels of the housing structure shelters disclosed herein are coated with a specialized polyurea coating, which is a very rugged coating that is completely waterproof, mold-proof, with no corrosion. It is noted that the same polyurea coating is used by the military for blast mitigation. Polyurea compounds are inert elastomeric substances created by combining an isocyanate compound with a synthetic resinous compound.
Each housing shelter structure goes together with screws (or other similar fasteners) that are installed using a powered screw gun, and the entire housing shelter structure comes apart with the same screw gun or other similar powered devices. The screws or threaded fasteners fit within pre-drilled holes, so that the threads of the screw or other fastener do not damage the panels or upright studs into which they are inserted. When the housing shelter structure is fully complete and fully assembled, there's a 360-degree connection point all the way around, floor to wall, wall to ceiling, back down around again. Therefore, when the wall panels stand up and the roof panels are laid in place on-site, there is no separate roofmg needed over the positioned roof panels and there is no separate siding shingles or boards required over the standing wall panels. The assembled housing shelter structure is completed and done. It is a fully panelized, interlocking system that's put together, fully with removable fasteners in predrilled holes. No permanently installed nails or roofing connectors are needed.
Because of the housing shelter is intended to be assembled and disassembled rapidly, and a multitude of times, it is formed of the aforementioned unique connection details, and as such, the assembled shelter housing structures can withstand Category 1 Hurricane force winds, depending upon how the housing structure is fastened to the ground.
The plumbing is also created in the factory setting, and may be installed in one single step. A bathroom module of the shelter housing structure is delivered as a singular unit and simply placed inside. The kitchen also formed as a manufactured module, which may be placed next to the bathroom module, so that water for the kitchen is accessible through the hollow space under the bathroom flooring. The kitchen module is essentially a one-piece kitchenette, with a stove, refrigerator, sink, etc. There's no additional plumbing required when the housing shelter structure is assembled on-site. Electric power wiring comes in a system of flexible harnesses that merely get rolled out in the house. The interior lighting is preferably provided by LEDs, which require very little electric power. Utility heating and air conditioning is efficient because of the use of a mini split extremely efficient HVAC unit, which is preferably powered by a solar panel. Therefore, the shelter housing structure can typically be one hundred percent “off grid” from local power utility companies, with these bathroom and kitchen module units and the mini-split HVAC unit. The standard base unit is a one-bedroom, one-bath unit, typically having interior floor space size of 12 feet×24 feet (i.e., 288 square feet). A two-bedroom unit can be proportionately larger, with more T-shaped uprights and rafters, combined with standard eight feet by 30 inch wide wall and roof panels. The house shelter unit can be altered by size, preferably being in increments of four feet to create shelters that may be one bedroom, two-bedrooms, three-bedrooms, etc. Optionally the housing shelter structure can be 16×32 feet as a base model, as opposed to the current model of 12×24 feet in dimensions. The uniqueness in these housing shelter structures is that they were designed not just to be assembled and built at one location, but they were specifically designed to also be disassembled and shipped to another geographic location in need. All of the structural elements and fasteners are specifically designed to come apart, without any peimanent elements, such as non-removable nails or adhesives. Therefore, the housing shelter structures can be disassembled, cleaned, flat packed, stored in a 16-foot pod, and used at a different location at a different time, over and over again.
Everything arrives at the new site in the transportation pod, including the kitchen, the bathroom, the doors, and the windows, which may already be installed in some of the panels. All of the components of each housing shelter structure are constructed in a factory, piece-by-piece, and then assembled in place, in the field of the geographic area in need, due to natural disasters, such as flooding, fire, earthquake or other weather or man-made disasters.
But, when the housing shelter structures are disassembled, there is zero footprint left at the previously build site. Everything is left undisturbed, and the build site is vacated as if the assembled housing shelter structure was never there.
The assembled housing shelter structures are particularly suited for a natural or man-made disaster area that needs quick, well-constructed homes for people who have lost their homes.
The main focus of the method of assembling rapidly built housing shelter structures is primarily on disaster relief, but the housing shelter structures can function as remote recreational camping or hunting cabins up in wooded and other remote areas. The housing shelter structures can also function as a recreational lakeside fishing cabin, or they can be assembled in a residential backyard to be used by an aging parent that wants a little bit of separation from grown-up children occupying a primary residence.
These shelters are suitable for purchase by the United States Federal Emergency Management Agency (FEMA), which organization may install the housing shelter structures at various locations for residential occupancy in disaster areas, where people in need occupy these housing shelter structures for a period of time, such as for six, eight or ten months, after which the housing shelter structures are disassembled, cleaned and inspected for subsequent assembly elsewhere. Any damage to any components results in replacement of the damaged component before it's packed in a transportation and storage pod for subsequent reuse. Therefore, the life cycle assembly and occupancy costs on these housing shelter structures is very low.
The housing shelter structures can be transported all over the world in a storage and transportation pod and be assembled/reassembled in about a day's time so that, by the end of the assembly day, somebody in need of immediate substitute housing can be living within a well-constructed housing shelter structure that is energy efficient, comfortable, and beautiful in architectural exterior and interior occupancy.
For example, while the protruding exterior ribs of the uprights and roof rafters' function in a utilitarian way to nest the wall or roof panels tightly in place, with accurate plumb lines established and weatherproofing stability, the array of these protruding buttress-like exterior support elements offer a crisp design element to the exterior look and feel of the housing shelter structure itself. These design elements greatly enhance the shape of the housing shelter structure, while maintaining its utility as a rapidly assembled or disassembled housing shelter structure for persons in need after a natural or man-made disaster.
The present invention can best be understood in connection with the accompanying drawings. It is noted that the invention is not limited to the precise embodiments shown in the following drawings, in which:
The present invention has broad applications to many technical fields for a variety of articles. For illustrative purposes only, a preferred mode for carrying out the invention is described herein, for a structurally sound quick assembly deployable and reusable housing shelters is assembled and disassembled at natural or man-made disaster sites in need of emergency housing shelters for residents.
For example, as shown in drawing
The modular house shelter unit 1 also includes a gabled roof 3 provided with a front roof portion 3a and a rear roof portion 3b. The roof 3 includes a plurality of pairs of roof rafters 20; each roof rafter 20 formed with a T-shaped cross-section having a base leg 22 and an outstanding web leg 24 protruding away from the base leg of the rafter 20. Each pair of roof rafters includes a first rafter 20, a second rafter 21, and a connector 44. Each connector 44 is configured to join a first end 20a of the first rafter 20 to a first end 21a of the second rafter 21 to form a triangular, gabled shape, wherein each respective pair of roof rafters 20, 21 are positioned, in the triangular shape, to rest upon, and releasably secure to, an opposing pair of the plurality of uprights 10, 10a. The roof 3 also includes a plurality of roof panels 40, 40a wherein each of the plurality of roof panels 40, 40a is configured to nest in modular spacing 25 between respective pairs of outstanding legs 24 of each adjacent pair of the roof rafters 20, 20a, to form a gable roof 3 without a conventional ridge plank.
The roof connectors 44 are preferably a hinge, such as, for example, a pivoting hinge strap, where each hinge 44 is configured to pivotally couple the first end 20a of the first rafter 20 to the first end 21a of the second rafter 21, being thereby configured to occupy a retracted position for transport. The first and second rafters 20, 21 are positioned substantially parallel to each other, and in an extended position, where the first end 20a of the first rafter 20 butts against the first end 21a of the second rafter 21, and the first and second rafters 20, 21 form the gabled triangular shape of the roof.
The components of the modular house shelter unit 1, include namely a foundation 4 (which may be concrete), pier footings 5 (which may be made of concrete), circumferentially extending exterior rim frame joists/girders 6, parallel interior floor beams 52 supporting insulated floor panels 50, to form a complete floor 50a, (as shown in

To further inhibit water intrusion, a small bottom portion of between six and fifteen inches, preferably twelve inches, of the bottom length of the wall panels 30, extends down below the height of the floor panels 50, so that no water will seep below the bottom of each wall panel into the floor of the housing shelter unit 1. It is noted that the floor panels are similar in material and configuration to the wall and roof panels 30, 40, in that each foam filled panel, whether it be wall, roof or floor panels are each about two to three inches in thickness. The wall and roof panels are preferably thirty inches wide and eight feet in length, but the floor panels can have a smaller width and horizontal length than the wall panels 30 and roof panels 40. It is also noted that the wall panels of the front and rear facades 2a and 2b, as well as the roof panels 40 are rectangular with dimensions of thirty inches in width by eight feet in length, with a thickness of between two and three inches. However, for the left and right end facades 2c and 2d, the 8-foot by 30-inch wall panels have cutouts to accommodate the triangular gable shape of the ends of each housing shelter unit 1. For example, the end wall panel 30 in the middle of the gabled sides will have an angled, equal sided peaked top portion, but the adjacent side wall panels 30, 30 will have an angular portion of opposite angles, depending upon which side of the middle panel 30 they are located adjacent to.
