services to victims. Prefabricated structures suited for easy and
quick deployment can further be used in other settings where
preexisting utilities may not be present for temporary use such as
at construction sites, or for more permanent use, such as at
remote, undeveloped homestead.

DETAILED DESCRIPTION
[0044] Common reference numerals are used throughout the drawings
and detailed description to indicate like elements; therefore,
reference numerals used in a drawing may or may not be referenced
in the detailed description specific to such drawing if the
associated element is described elsewhere.
[0045] Embodiments of a prefabricated structure and a system of
cooperating prefabricated structures in accordance with the present
invention can be quickly and efficiently anchored and deployed to
reduce setup time, set up expense, and site preparation. Such
embodiments can benefit structures intended for permanent use,
emergency use such as for disaster relief, and/or for planned
temporary use such as for classroom facilities and construction
site administration.
[0046] Referring to FIGS. 1A and 1B, an embodiment of a
prefabricated structure 100 in accordance with the present
invention is shown in a deployed arrangement. The prefabricated
structure 100 includes a shell 101, an extension 103 deployed from
the shell 101, and a deck 106 extending from an opposite side of
the shell 101 from the extension 103. As shown, the prefabricated
structure 100 is fixed in place by support posts 112 joined with a
concrete base anchored by rebar driven into the ground. The support
posts 112 can be adjusted vertically so that the prefabricated
structure 100 can be leveled. Existing techniques for determining
leveling can be applied to assist adjustment of the vertical
deployment of the support posts 112 from the frames of the shell
101 and extension 103. As will be described below, the
prefabricated structure 100 can be deployed in stages so that the
support posts 112 can be extended and fixed in a systematic
fashion.
[0047] The prefabricated structure 100 can be substantially
self-contained, in that it need not be connected to preexisting
electrical grids, water and/or sewage service lines. The
prefabricated structure 100 includes a service pack comprising one
or more batteries (shown below) providing electrical power for
lighting and appliances, as well as for electrical tools and
gadgets accessorizing the living space. The one or more batteries
are recharged by a solar panel 108 connected with a roof of the
extension 103. The service pack further comprises a generator for
providing electrical power to the prefabricated structure 100
and/or supplementally recharging the one or more batteries. The
generator can be driven by propane, or some other liquid or gas
fuel.
[0048] Panels 114,115,117 can be mated with the shell frame 102 and
extension frame 104 to provide exterior walls and to seal the
prefabricated structure 100 from moisture and suppress undesirable
heat exchange with the environment. Panels can be selected based on
the function or configuration of structures within the
prefabricated structure 100. For example, the prefabricated
structure of FIGS. 1A and 1B can include panels 114 connected with
the extension frame 104 having windows to pass natural light into
the extension 103. Two different types of panels 116a,b are
connected to the shell frame 102 along the length of the shell 101
to provide a wall (116a) and an entryway (116b). In other
embodiments, some other combination and shape of panel can be used.
For example window panels can substitute for solid panels.
[0049] Referring to FIGS. 1C and 1D an alternative embodiment of a
prefabricated structure 200 in accordance with the present
invention differs from the embodiment of FIGS. 1A and 1B in that
panels having three different configurations 116a-c are connected
along the length of the shell frame 102. A panel 216c including a
window is connected with the shell frame 102 and positioned
adjacent to a panel 116b providing an entrance to the prefabricated
structure 200. Use of panels connected between support structures
of the frames 102,104 allows a prefabricated structure in
accordance with the present invention to be adapted to intended use
and/or customized to individual taste. Use of panels may further
require only partial replacement when the prefabricated structure
is damaged by severe weather, for example, or vandalism, or
refurbished for reuse.
[0050] The roofs of the extension 203 and shell 201 of the
prefabricated structure 200 of FIGS. 1C and 1D are removed to
illustrate furniture and appliances that can be installed within
the prefabricated structure 200 prior to delivery to a site. The
shell 201 comprises a kitchen having kitchen appliances 270a, and a
bathroom having bathroom fixtures 270b separated from the kitchen
by a wall 219a. As shown, the shell 201 further comprises sleeping
quarters separated from the entrance by a wall 219b and having a
pair of bunks 272d. The extension 203 includes sleeping quarters
separated into three rooms each of which includes a pair of bunks
272a-c. The bunks are pivotably connected with a fixed wall or
structure separating the shell 201 from the extension 203, and
pivot down into place upon deployment of the extension 203. Walls
218a,b separating the rooms of the extension 203 are positioned
across the shell 201 when the extension 203 is nested within the
shell 201, and are drawn out when the extension 203 is deployed.
The walls 218a,b can be received in the shell 201 so that the walls
218a,b fill unoccupied space. For example, a wall 218a can be
received in a space provided between appliances 270a of the
kitchen. The prefabricated structure 200 as shown is intended to
provide shelter for eight occupants.
[0051] Referring to FIG. 1E a further embodiment of a prefabricated
structure 300 in accordance with the present invention configured
for use as an administrative unit is shown. The shell 301 of the
prefabricated structure 300 includes panels having two different
configurations 116a,b connected along the length of the shell frame
102. Further, the extension 303 of the prefabricated structure 300
includes panels 314 connected along the length of the extension
frame 104 having windows that extend lower than windows of
previously described embodiments. The shell 301 comprises a
receiving area 370a, a bathroom having bathroom fixtures 370b
separated from the receiving area 370a by a wall 319a. The shell
301 further comprises an office 370c separated from the receiving
area 370a by a wall 319b and having a desk that pivots down from a
collapsed position upon deployment of the prefabricated structure
300. The extension 303 includes a reception desk 372a that pivots
down from a collapsed position within a wall 318a. The reception
desk 372a separates two offices 372b,c of the extension 303 and the
two offices 372b,c are accessed by way of the receiving area 370a.
Each office 372b,c includes a desk that pivots down from a
collapsed position upon deployment of the extension 303 from the
shell 301. As above, walls 318a,b separating the offices 372b,c of
the extension 103 are positioned across the shell 301 when the
extension 303 is nested within the shell 301, and are drawn out
when the extension 303 is deployed. The walls 318a,b can received
in the shell 301 so that the walls 318a,b fill unoccupied space.
The prefabricated structure 300 as shown can serve as a stand-alone
administration building, for example at a construction site, or can
be associated with a plurality of other units, for example, the
prefabricated structure 300 can be connected with a cluster of
cooperating units and serve as the administration unit for the
cluster of cooperating units.
[0052] Referring to FIG. 1F a still further embodiment of a
prefabricated structure 400 in accordance with the present
invention configured for use as a medical unit is shown. The shell
401 of the prefabricated structure 400 includes panels having two
different configurations 116a,b connected along the length of the
shell frame 102. Further, the extension 403 of the prefabricated
structure 400 includes panels 314 connected along the length of the
extension frame 104 having windows that extend low. The shell 401
comprises a reception area 470a, a bathroom having bathroom
fixtures 470b separated from the reception area 470a by a wall
419a. The reception area includes a reception desk and seating. The
shell 401 further comprises an examination room 470c separated from
the reception area 470a by a wall 419b and having an examination
table that pivots down from a collapsed position upon deployment of
the extension 403. The extension 403 includes three examination
rooms 472a-c including an examination table that pivots down from a
collapsed position and a pair of additional tables for holding
instruments, charts, etc. that pivot down from a collapsed position
upon deployment of the extension 403 from the shell 401. As above,
walls 418a,b separating the examination rooms 472a-c of the
extension 403 are positioned across the shell 401 when the
extension 403 is nested within the shell 401, and are drawn out
when the extension 403 is deployed. The walls 418a,b can received
in the shell 401 so that the walls 418a,b fill unoccupied
space.
[0053] The embodiments of prefabricated structures shown in FIGS.
1A-1F comprise substantially the same frame structure. Referring to
FIG. 2A, the frame structure is shown without panels or furniture,
and comprises the extension frame 104 nested within the shell frame
102. A floor support of the extension frame 104 telescopingly
engages a floor support of the shell frame 102 and a floor of the
extension 103 can be deployed in roughly the same plane as the
floor of the shell 101. The roof support of the extension frame 104
is positioned at a height shorter than a height of the shell frame
102.
[0054] Referring to FIGS. 2B and 2C, the shell frame 102 is shown
in two portions. An inner portion is shown in FIG. 2B comprising a
first pair of roof beams 120a1,b1 extending lengthwise along the
shell and a second pair of roof beams 122a1,b1 extending between
and transverse to the first pair of roof beams 120a1,b1. The roof
beams 122a1,b1 are connected with corresponding floor beams
128a1,b1 of the floor by vertical structures 124a-d (vertical
structures that provide primary resistance to compressive forces
are hereinafter referred to as columns). The columns 124a-d include
cavities extending through at least a portion of the columns 124a-d
to house support posts 112a-d extendable from the bottoms of the
columns 124a-d and eye hooks 113a-d detachably received in a cavity
in the tops of the columns 124a-d. The eye hooks can enable
positioning of the prefabricated structures through use of a crane
or helicopter, for example. An additional vertical support 123
extends down from a roof beam 120a1. An outer portion of the shell
frame 102 is shown in FIG. 2C comprising a pair of floor beams
134a,b extending lengthwise along the shell and a pair of beams
128a2,b2 having a J-shaped cross-section (seen more clearly in FIG.
2D) fixedly connecting with the floor beams 128a1,b1 of the outer
portion to define a slotted beam 128a,b extending between and
transverse to the pair of floor beams 134a,b of the inner portion.
FIG. 2D is a partial cross-section of the extension frame 104
received within the shell frame 102, illustrating the relationship
between the outer portion and inner portion of the shell frame 102
and between the shell frame 102 and the extension frame 104. As
shown, the outer portion of the shell frame 102 is fixedly
connected with the inner portion of the shell frame 102 so that a
slotted beam 128a is formed that receives a floor beam 148a of the
extension frame 104 in a telescoping fashion, while passing a wall
base 146a and vertical structures 144a of the extension frame 104.
The inner portion comprises a pair of inner roof joists 122a2,b2
connected with or integrally formed with the second pair of roof
beams 122a1,b1 of the outer portion and a plurality of roof joists
126a-e extending between and transverse to the first pair of roof
beams 122a2,b2. The inner portion further comprises a plurality of
floor joists 136a-e extending between and transverse to the floor
beams 134a,b and spaced along the shell frame between the pair of
slotted beams 128a,b and a series of vertical structures 132a-e
extending between a floor beam 134a and a roof beam 120a. In an
embodiment, the vertical structures 132a-e can be C-channels, as
explained in more detail below.
[0055] In a preferred embodiment the outer portion is fabricated
from aluminum or an aluminum alloy and the inner portion is
fabricated from steel or a steel alloy. The components of the inner
portion and the outer portion can be welded, riveted, bonded or
otherwise fixedly connected. In other embodiments, the inner
portion and outer portion can be fabricated from the same material.
Further, the slotted beam 128a,b can comprise the floor beams
128a2,b2 of the inner portion welded to a separate pair of beams
128a1,b2, or alternatively, the slotted beam can be fabricated from
a single piece of material of a single composition. One of ordinary
skill in the art in view of the teachings contained herein will
appreciate the myriad different techniques for fixedly connecting
the components of the shell frame, and the various tradeoffs in
strength and weight for using different materials in fabricating
the shell frame.
[0056] Referring to FIG. 2E, the extension frame 104 is shown. The
extension frame 104 comprises an extension roof support and an
extension floor support. The extension floor support includes a
main floor beam 150 extending lengthwise, a pair of extension floor
beams 148a,b extending from the main floor beam 150 and telescoping
from the respective slotted beams 128a,b of the shell frame 102,
and a pair of extension joists 152a,b extending from the main floor
beam 150 and telescoping from corresponding floor joists 136b,d of
the shell frame 102. The extension roof support includes a pair of
roof beams 140a,b extending lengthwise along the shell and seven
roof joists 142a-g extending between and transverse to the pair of
roof beams 140a,b. The roof beams 140a,b are connected with the
floor beams 148a,b by columns 144a-d. The columns 144a-d include
cavities extending through at least a portion of the columns 144a-d
to house support posts 112e-g extendable from the bottoms of the
columns 144a-d. A series of vertical structures 156a-e extend
between the floor beam 150 and a roof beam 140b. In an embodiment,
the vertical structures 156a-e can be C-channels, as explained in
more detail below. Two of the vertical structures 156b,d support
walls of the extension 104 and are connected to corresponding wall
bases 154a,b. Each wall base 154a,b is connected to an additional
vertical wall support 158a,b. The vertical wall supports 158a,b are
connected with the roof beam 140a by a ledge 160a,b. The vertical
structure 156b,d, the wall base 154a,b, and the vertical wall
support 160a,b together support a wall dividing sections of the
extension 103. The wall protrudes past the roof beam 140a of the
extension to provide the ledge 160a,b, which can apply a force to a
complementary joist 126b,d of the shell roof to assist in
maintaining the cantilever extension approximately horizontal
during deployment. As shown, a pair of spring biased rollers 162a,b
extend from each ledge 160a,b. The rollers 162a,b are biased toward
the complementary joist 126b,d to apply force to at least partially
counterbalance the moment force along the portion of the extension
telescoped from the shell frame 102 while rolling to reduce
impeding deployment of the extension 103 from the shell 101. As can
be seen more clearly in FIG. 2D, the wall base 154a,b is separated
from the floor joist 152a,b by some small gap G so that the wall
base 154a,b passes over the floor joist 134a of the shell frame 102
in a sliding, or separated fashion.
[0057] It can be desirable to seal the prefabricated structure from
environmental elements at least in a deployed configuration, and
preferably in both a deployed configuration and a nested
configuration. In a preferred embodiment of a prefabricated
structure in accordance with the present invention, a T-flange can
extend from structures along the perimeter of the extension. The
T-shaped flange can extend inward from the extension-side columns
124b,d and the extension-side roof beam 120b. Referring to FIGS.
3A-3D and 3F, the t-shaped flange 125 is shown separate from the
extension-side column 124b and extension-side roof beam 120b to
more clearly explain the relationship between the extension and the
T-shaped flange 125. In the embodiment shown, a pair of trim pieces
is connected along the at least three edges of the extension,
including the extension columns 144a-d and the roof beams 140a,b. A
trim piece can have, for example, an L-shape that complements one
half of the T-shaped flange 125. The trim pieces complement
separate halves of the T-shaped flange 125. Referring to FIG. 3A,
the extension is shown in a closed position with a trim piece 145b
mating with the T-shaped flange 125. As the extension 103 deploys,
the trim piece 145b decouples from the T-shaped flange, as shown in
FIG. 3B. As the extension reaches full deployment, the trim piece
145a at an opposite end of the extension approaches the T-shaped
flange 125, as shown in FIG. 3D and FIG. 3E, which shows the
T-shaped flange 125 connected with and extending from the
extension-side column 124a. The trim piece 145a mates with the
T-shaped flange as the extension 103 reaches full deployment, as
shown in FIG. 3F. Referring to FIG. 3G, rubber gaskets are fixedly
connected with one or both of the T-shaped flange 125 and the trim
piece 145a so that when the structures are mated, a seal is formed,
to suppress penetration of water and/or air at the flange.
[0058] Referring to FIG. 4A-4D, floor panels 182a-182c of the
extension 103 pivot from a collapsed, upright position to a flat,
seated position upon deployment of the extension frame 104. The
floor panels 182a-182c are pivotably connected with one or both of
the shell frame 102 and the shell floor 180 and in a collapsed
position are arranged vertically so that the weight of the floor
panels 182a-182c is applied to the wall of the extension 103.
Referring to FIGS. 4B-4D, as the extension frame 103 deploys, the
floor panels slide down the wall of the extension 104 moving from
the deployed position of FIG. 4B to the partially deployed position
of FIG. 4C, to the fully deployed position of FIG. 4D. As can be
seen in FIG. 4D, the telescoping floor joists 152a of the extension
frame 103, include a lock feature that extends laterally from the
floor joist 152a and that receives a complementary lock feature of
the floor panel 182a. The lock features enables the floor panel
182a to lock into position so that a surface of the floor panel
182a is generally coplanar with a surface of the floor joist 152a
and approximately co-planar with floor panels 180 of the shell
101.
[0059] Referring to FIGS. 5A-5C, floor joists 136a-136e and floor
beams 148a,b of the shell frame 102 can be used to position support
structures below floor panels of the shell 101. The floor joists
136a-136c and the floor beams 148a,b can include lock structures
resembling the lock structures of the extension floor joists
152a,b. Between a pair of floor joists 136a-136c, or a floor beam
148a,b, one of a supply water tank for providing water to the
prefabricated structures (e.g., to appliances) and a grey water
tank for receiving used water for filtering and dumping and/or
recycling can be positioned. The tank 190e of FIG. 5B is shown open
for illustration of the geometry of a typical tank. However, in
embodiments of the present invention, supply water tanks and grey
water tanks will be enclosed. Further, the tank 190e includes a
single dividing structure dividing the tank to at least partially
control movement of water within the tank. In further embodiments,
a supply water tank and/or grey water tank of the prefabricated
structure can be baffled to further control movement of water in
the tank. Controlling movement of water within the tank can resist
catastrophic unbalancing of the prefabricated structure during
periods of high winds, such as during tropical storms or
hurricanes. Water within the tank can add weight to the
prefabricated structure while lowering a center of gravity of the
prefabricated structure, thereby increasing stability of the
prefabricated structure. In a preferred embodiment shown in FIG.
5A, the prefabricated structure can include four supply water tanks
and two grey water tanks, so that water tanks are positioned along
substantially the length of the shell 101. Referring to FIG. 5C,
the tanks can be supported by locking structures of the floor joist
136e that complement structures of the tank 190e. As shown, the
tank is supported so that a top of the tank ist below the surface
of the floor joist 136e. Floor panels (180 in FIG. 4A). of the
shell 101 can be positioned above the tanks so that the floor
panels 180 are supported by the tanks 190a-e or alternatively by
additional features of the floor joists 136a-e.
[0060] Referring again to FIG. 5A, a service pack 192 for use with
the prefabricated structure is shown positioned within the shell
frame 102. As shown, the service pack 192 comprises a heat pump 194
and propane tanks 196 for use to fuel a generator or utilities such
as cooking appliances. Though not shown, the service pack 192 can
include batteries, inverter/rectifier equipment, and the
aforementioned generator. As shown, the heat pump 194 can be
accessed by drawing the heat pump 194 from the end of the shell
frame 102 between adjacent columns 124a,124b. However, the heat
pump 194 is typically deployed for long periods of time, and such
an arrangement may be disadvantageous, for example where
cooperating prefabricated structures are positioned in close
proximity to one another. FIG. 5D-5F illustrates an embodiment of a
service pack 292 in accordance with the present invention for use
with prefabricated structures as described herein, for example. The
service pack 292 comprises a heat pump 294 mounted on a cabinet
293. The cabinet 293 is lockable to prevent components of the
service pack 292 from being removed. The heat pump 294 rests on a
platform that can be raised through the roof of the shell, as shown
in FIGS. 5E and 5F. The shell frame 102 comprises an additional
roof joist 126z so that the heat pump 294 and a door or other
structure (not shown) sealing the roof when the heat pump 294 is in
an undeployed position is supported between the additional roof
joist 126z and the roof joist 126a of the shell frame 102 as
described above. The heat pump 294 can be raised by a motor or
mechanically. With the heat pump raised through the roof of the
shell, the heat pump 294 can be left deployed without potentially
interfering with additional prefabricated structures that may be
placed in close proximity so that the prefabricated structures can
cooperate in one or both of electrical and water utilities.
Further, the heat pump 294 may function more efficiently when
placed above the prefabricated structure, allowing air to more
freely circulate around the heat pump 294. Fuel tanks such as
propane tanks 296 can be drawn from the front of the shell 296.
Because fuel tanks 296 are only accessed briefly for replacement,
the fuel tanks 296 do not protrude from the shell when not
serviced. The cabinet 293 also contains a bank of batteries 295
that are recharged by electrical wiring connected with solar panels
of the extension roof and/or by a generator that can be fueled by
the propane tank 296. The cabinet 293 also includes inverter and/or
rectifier equipment 297 to convert DC to AC and AC to DC. Use of a
unified or partially unified service pack 292 can increase likely
reusability of service components of the prefabricated structure,
for example when the prefabricated structure is refurbished for
deployment at an alternative site.
[0061] The shell frame 102 and extension frame 104 can provide
channels for communicating one or both of electrical wiring and
water ducts. FIG. 6A illustrates an extension frame 104 of
embodiments such as shown in FIGS. 1A-5E. Electrical wiring can
communicate, for example, electrical power collected from a solar
panel arranged on a roof of the extension to a battery or bank of
batteries, and can communicate electrical power from the battery or
bank of batteries to lighting and/or outlets of the prefabricated
structure. Electrical wiring can be connected between the extension
103 and the shell 101 as a single harness that extends through both
frames when deployed or undeployed, or alternatively the electrical
wiring can exist as separate harnesses extending through the shell
101 and extension 103, respectively, that can be connected upon
deployment of the extension 103 from the shell 101. The electrical
wiring rests or is seated within channels, for example as defined
by roof beams 140b,142a of the extension frame 104. Roofing can
overlay the channels to protect electrical wiring from
environmental elements. Such an arranged can protect electrical
wiring and water ducts from damage during transport and use and can
provide improved aesthetics by hiding electrical wiring and water
ducts. In alternative embodiments, the extension frame 504 can
comprise channels within roof beams 542a,540b arranged differently
than as shown in FIG. 6A. For example, the channels can face
outwardly.
[0062] Vertical structures of both the shell frame 102 and the
extension frame 104,504 can comprise C-channels adapted to receive
L-channels 372a,372b fixedly embedded in panels 314a or fixedly
connected with panels 314, as shown in FIGS. 6C-6G. Embodiments of
prefabricated structures in accordance with the present invention
can be configured to suit myriad different applications and tasks
using the shell frames 102 and extension frames 104,504 described
above, by selecting and mating panels having suitable features with
the shell frame 102 and extension frame 104,504. The panel 314a of
FIG. 6C resembles panels 314 of FIGS. 1E and 1F, and includes three
windows 376 that extend along a large portion of the height of the
panel 314a. The panel 314a can comprise, in an embodiment, a
structure insulated from environmental elements such as rain and
wind. The panel 314a can further resist heat exchange between air
within the prefabricated structure and the environment, helping to
reduce heating of the prefabricated structure by hot outside air,
and cooling of the prefabricated structure by cold outside air. The
panel 314a can comprise any material or combination of materials
that allow an L-channel to be embedded or fixedly connected with
the panel 314a, and that provides at least insulation from moisture
and wind. For example, as shown in FIG. 6E, the panel can include
exterior siding bonded to insulation, bonded to a light, rigid
material such as plywood which is sealed by a film, such as vinyl.
As shown, the L channel 372a,372b is fixedly embedded between the
exterior siding and insulation of the panel 314a. The panel 314a
can be mated with adjacent vertical structures 156a so that the
L-channel 372a,3732b fits in the C-channel of the vertical
structure 156a and the C-channel is seated between the panel 314a
and the L-channel 372a. A seal 177a can be bonded, for example
adhesively, with the C-channel so that the L-channel presses
against the seal 177a, preventing environmental elements from
penetrating the prefabricated structure. A shim 374a can be placed
between panels 314a to force panels 314a against opposite sides of
the C-channel 156a, improving the seal. An alternative embodiment
of a panel is shown in FIGS. 6F and 6G comprising an L-channel
bonded to an exterior of a panel 514b rather than embedded. The
shim 574a caps adjacent L-channels rather the urging them apart.
The panel 514b of FIGS. 6F and 6G further comprises an L-channel
578b mating with a roof beam 540b of the extension frame. The
window 376 of the panel is shown partially separated from the panel
514b.
[0063] FIGS. 7A-7G illustrate an embodiment of a method of
deploying a prefabricated structure 300 including a shell and an
extension nested within the shell in accordance with the present
invention. The method comprises positioning a container 2 or
support surface such as a flat-bed or rail car supporting the
prefabricated structure at a site. The prefabricated structure 300
can be supported on a plurality of rollers 384 and/or casters
connected with the prefabricated structure 300. The prefabricated
structure 300 can be urged so that a first set of roller 384
extends from the container 2. As shown in FIG. 7B, the first set of
rollers can be separated from columns of the prefabricated
structure 300. A first set of support posts 312 can be lowered from
the columns. The support posts 312 can be lowered, in an
embodiment, using a worm gear device 388, such as shown in FIG. 7D.
A crank 386 can be mated with a gear 388 arrangement and rotated to
lower the support post 312. In alternative embodiments, the support
post 312 can be lowered using a motor. Once the support posts 312
are lowered, the support posts 312 can be anchored. The
prefabricated structure 300 is then drawn from the container 2 or
support structure so that more of the prefabricated structure 300
is cantilevered out from the container 2 or support structure.
Preferably, the prefabricated structure 300 is drawn so that a
column of the shell is cantilevered from the support surface. In a
fashion repeated at each pair of columns along the shell, a set of
rollers or casters is cantilevered from the support surface, and
separated from the column. Support posts are then lowered from the
column and anchored at the site. Referring to FIGS. 7E and 7F, once
the prefabricated structure 300 has been drawn from the support
surface, the extension 303 can be deployed from the shell 301. In a
preferred embodiment, a rack-and-pinion mechanism can be employed
to urge the extension 303 from the shell 301. The rack-and-pinion
mechanism can comprise a shaft extending from the floor beams of
the shell and through the floor joists of the shell, the shaft
including pinions mating with racks at each or several of the floor
joists and floor beams of the shell. The extension 303 can be
cantilevered from the shell 301 in a fully deployed position. Once
the extension is deployed, support posts of the extension 303 are
extended from columns of the extension 303. The support posts are
then anchored. Referring to FIGS. 7F and 7G, the deck 316 can be
deployed, for example to be mated with a set of support posts.
[0064] In alternative embodiments, the prefabricated structure may
be suspended by way of cables attached to eyehooks over a
designated deployment site. The prefabricated structure may be held
suspended over the site by a crane or other device while support
posts are extended from columns of the shell and anchored in
position at the site. Once the support posts are extended, the
extension can be deployed from the shell. After deployment of the
extension, support posts of the extension can be lowered an
anchored in position at the site. In still further embodiments, the
prefabricated structure can be positioned over a site by a
forklift. The prefabricated structure may be held suspended over
the site by the forklift while support posts are extended from
columns of the shell and anchored in position at the site. As
above, once the support posts are extended, the extension can be
deployed from the shell. After deployment of the extension, support
posts of the extension can be lowered an anchored in position at
the site.
[0065] It should be noted, and will be apparent upon review of
FIGS. 1A-1F described above, that the prefabricated structure 300
itself can act as a container. When the extension 303 is nested
within the shell 301, the prefabricated structure is sealed.
Embodiments of prefabricated structures in accordance with the
present invention are advantageously designed to be moved without a
sheltering container, so that prefabricated structures can be
placed directly on flatbeds, railroad cars, cargo ships, etc.
without first being placed in containers. Such a scheme for
transporting the prefabricated structure can reduce transport and
setup time, simplify setup and reduce an amount of space required
for setup (the prefabricated structure need not be drawn lengthwise
from a semi-truck, for example). Further, as noted above the
columns of the shell frame can include detachable eyehooks and
rollers that are fitted at mounting points within the columns.
Columns provide opportune locations for locking additional
prefabricated structures in place when stacked for transport on a
cargo ship, for example. Thus, multiple prefabricated structures
can be stacked as high as can be supported by their frames (which
can vary with materials selected for the frame) and transported on
cargo ships to deliver to disaster relief sites, such as in
Thailand and Indonesia following the Boxing Day tsunami, or Africa
to assist relief efforts for refugees in Darfur, Sudan.
[0066] Embodiments of methods of using prefabricated structures and
systems of cooperating prefabricated structures in accordance with
the present invention can be applied to provide potential
logistical solutions to multiple logistical challenges, for example
encountered at a disaster area. The system can comprise two or more
cooperating prefabricated structures, each prefabricated structure
including a shell and a deployable extension. The prefabricated
structures can cooperate in one or more ways. Cooperation can be
simple, for example, the prefabricated structures can include decks
that are sufficiently close to one another so as to combine to form
a common walkway. Alternatively, cooperation can determine a
selection of panels (e.g., window height, entry positioning and
type) for the shell and extension, and the type of amenities and
furniture contained within the prefabricated structures. For
example, referring to FIG. 8, an embodiment of a system of
cooperating prefabricated structures in accordance with the present
invention is shown comprising eight prefabricated structures
connected together and providing utility for multiple different
logistical challenges. The system as shown comprises eight units
that are arrangeable as desired to support efficient logistical
flow, and the prefabricated structures are sized to be deployed as
a system in a tightly configured arrangement. Thus, for example, a
length of two deployed prefabricated structures is approximately
equal in distance as a width of two deployed prefabricated
structures and a length of one deployed prefabricated structure.
Thoughtful dimensioning of the prefabricated structure to generally
conform with shipping standards, as well as with deployment
configurations can enable a cooperating relationship that is
substantially complete upon deployment of the prefabricated
structures individually. The cooperating relationship and tight
configuration of units allows compact, efficient deployment, safety
of use by design (e.g., little to no gaps in walkways formed by
pivotably deployed decks), and improved logistical flow. The
configuration also allows electrical utilities and water utilities
to be predictably linked. The system of cooperating prefabricated
structures of FIG. 8 can be expanded or reduced in a scaling
fashion, so that in an alternative embodiment only the four inner
prefabricated structures are linked together (e.g., the two
prefabricated structures in the center and the two prefabricated
structures arranged perpendicularly to the center structures).
[0067] Referring again to FIG. 8, as shown, the system comprises a
pair of bunk units ("ERU-BUNK") positioned at opposite ends of the
system. The bunk units can include amenities and furniture
resembling the prefabricated structure of FIGS. 1C and 1D, for
example. The system also comprises an administration unit
("ERU-ADMIN") that includes amenities and furniture resembling the
prefabricated structure of FIG. 1E. The system also comprises a
medical unit ("ERU-MED") positioned between the bunk units and
opposite the administration unit. The medical unit can include
amenities and furniture resembling the prefabricated structure of
FIG. 1F. In addition to prefabricated structures having previously
described amenities, furniture, and functionality, myriad different
functional configurations can be provided to prefabricated
structures including shell frames and extension frames as described
above.
[0068] As shown in FIG. 8, two commissary units ("ERU-CC1 & 2")
are provided to facilitate meetings and provide waiting areas for
visitors to the administration unit and medical unit, for example.
Further, an additional, dedicated communication unit ("ERU-COMM")
is shown which can provide a common hub data uplink/downlink and
communication. For example, the communication unit can include
broadcast transmitting and receiving equipment. Where desired, one
or more of the prefabricated structures can electrically and
communicatively connected to each other so that the prefabricated
structures combine to provide a shared power grid. Such an
arrangement can provide flexible distribution to electricity,
allowing electrical power to be prioritized to one of the
prefabricated structures of the shared grid. For example, medical
units or communication units may be given priority where power is
low. One or both of the shell frame and the extension frame of the
prefabricated structures can include channels that can be accessed,
allowing wire harnesses or electrical cables to be connected with
other prefabricated structures.
[0069] Further, an additional, dedicated water filtering unit
("ERU-WFSS") is shown which can provide a common supply water
collection, filtration and distribution facility, as well as a grey
water processing and dump facility. A water filtering unit can
increase an overall volume of water available and provide more
efficient processing of supply water that may be collected from
rain water or bottled water provided by relief agencies, etc., by
providing a larger and more flexible space for including equipment.
Likewise, grey water can be collected from use, treated and dumped,
for example in a ditch or cesspool (although the water may be
sterile and usable for example for growing foods). One or more of
the prefabricated structures can be connected with the water
filtering unit so that the prefabricated structures combine to
provide a shared water system. Such an arrangement can potentially
increase an overall available amount of water by allowing
dedication of water tanks in some of the prefabricated structures
to supply water, for example, while the water filtering unit
quickly filters and disposes of grey water.
[0070] As mentioned above, the water filtering unit can collect
rain water and filter the water for use by the prefabricated
structures. Referring to FIG. 9, one or more of the decks providing
walkways for the system can further include canopies 198 anchored
to columns 124a of the shell frame 102, for example, the canopies
198 providing shade to the walkways and shielding the walkways from
rainfall. In such embodiments, the canopies 198 can include
mounting structures 199 that direct water beading and rolling from
the canopies 198 to gutters and to tubing housed in channels of the
shell frames and/or extension frames of the prefabricated
structures. The tubing can communicate the water to supply water
tanks, or alternatively to the water filtering unit.
[0071] Embodiments of methods of distributing a prefabricated
structure in accordance with the present invention can be applied
to manage construction and deployment costs associated with the
prefabricated structures and systems of cooperating prefabricated
structures. A method can comprising providing a prefabricated
structure for use at a first site, the prefabricated structure
including a shell with a shell frame, a plurality of wall panels
mated with the shell frame, and a plurality of floor panels mated
with the shell frame, and an extension with an extension frame, a
plurality of wall panels mated with the extension frame, and a
plurality of floor panels mated with the extension frame. The
prefabricated structure can be used at a site, such as a disaster
relief site, and then recovered from the site for refurbishment.
Recovery can comprise a series of steps approximately reversed from
the steps of deployment. For example, a prefabricated structure can
be recovered by retracting the support posts of the extension into
the extension, nesting the extension within the shell, retracting a
first set of supports posts of the shell into the shell, joining a
rollers to columns of the shell, urging a transport surface so that
the set of roller is positioned on the transport surface and can
roll on the surface. One of the transport surface and the shell is
urged in stages at each pair of columns so that the support posts
can be retracted within the column and replaced with rollers that
can transfer weight of the prefabricated structure to the transport
surface, until the prefabricated structure is wholly received on
the transport surface. The prefabricated structure can then be
transported back to a refurbishment facility and refurbished.
Refurbishment may include replacing one or more floor panels and/or
wall panels, amenities and/or furniture. Prefabricated structures
can be refurbished so as to support a different use or the same
use. It is generally believed that the shell frame extension frame
is likely to be undamaged, enabling multiple uses of the
prefabricated structure at multiple sites.
