Description
This invention relates to a portable housing structure, and more
particularly, to a prefabricated, self-packaging housing
structure.
Prefabricated, portable housing structures are now commonly used by
the military and many commercial operations such as mining,
drilling and exploration setups. A wide variety of structures are
in use, and many have proved unsatisfactory or at least have
undesirable characteristics. Some are difficult and awkward to
erect and require considerable time to dismantle. In some cases,
after having been erected and dismantled, the structure cannot be
readily assembled again, and indeed some are not constructed in a
manner to be disassembled for relocation. Additionally, some types
of structures are awkward to handle when in the dismantled
condition and are subject to weather damage. Although structures
have been developed to have a self-packaging feature, these
structures have included heavy and bulky framework to permit
stacking of the dismantled structures, and have required
considerable hardware for fastening the components together either
in the shipping or erected condition. Since the housing structures
are used under extreme climatic conditions, many known housing
structures have not proved to be sufficiently weather
resistant.
According to the present invention, which overcomes the above
disadvantages, there is provided a box beam roof component having a
roof panel and downwardly depending edge members formed integrally
with the roof panel about the periphery thereof. The present
invention also includes a plurality of wall panels, a floor
component including a floor panel carried on a frame structure, and
tie-down means for securing the roof component to the floor
component with the wall panels held in a vertical position between
the edge members of the roof component and the floor component when
the housing structure is in the erected condition. The same
tie-down means are adapted to secure the roof component directly on
the floor component with the wall panels contained under the roof
component when the housing structure is in a shipping condition so
that entire structure is thus self-contained as a single easily
handled package. The roof component has means thereon for
engagement with the frame structure of a like structure, so that
the package, without any additional framework, can carry another
like structure on it in a stacked relation with one housing
structure carried directly on the roof component of another.
Preferably the bottom edge surface of the edge members and the
upper edge surface of the wall panels have matching keyslots and
keystrips. It is also preferable to have matching keyslots and
keystrips in the bottom edge surfaces of wall panels and the upper
peripheral portion of the floor panel. Moreover, the keyslots and
keystrips on the bottom edge surface edge members of the roof
component and the upper peripheral portion of the floor panel may
match. Thus, in the erected condition a good weather resistant
joint is provided between the wall panels and the roof and floor
components, and in the shipping condition the package formed by the
roof component and the floor component is well sealed.
Additionally, the matching keyslots and keystrips facilitate the
locating and accurate placement of components during assembly or
when placing the components in a shipping condition.
The tie-down means preferably include a plurality of members for
connection between the roof and floor components at spaced
intervals about the housing structure, each member including a
device of adjustable length, such as a turnbuckle, and an elongated
element, such as a cable, for connection to the device for securing
the roof component to the floor component when the housing
structure is in the erected condition. The device may be separable
from the element for use in securing the roof component to the
floor component when the housing structure is in the shipping
condition.

In the drawings, the reference numeral 10 generally denotes the
housing structure of the present invention, the housing structures
10, including a roof component 11, wall panels 12, 13, 14 and 15,
and a floor component 16. In the embodiment of the invention shown,
the floor plan of the housing structure is of rectangular shape,
wall panel 12 forming a front wall, wall panel 14 forming a back
wall, and wall panels 13 and 15 forming end walls.
The roof component 11 is in the form of an integrated box beam,
i.e., it has the configuration of a shoe-box lid, and thus
contributes greatly to the strength and rigidity of the housing
structure in either the erected or shipping condition. The roof
component 11 is basically formed by a roof panel 17, which in the
present invention is a flat horizontal member, and downwardly
depending edge members 18 about the periphery of roof panel 17 and
formed integrally with the roof panel 17. Thus in either
longitudinal cross-section or transverse cross-section the roof
component is of an inverted U-configuration with the roof panel 17
forming a web and the edge members forming downwardly depending
flanges. The roof panel 17 includes a plurality of joist members 20
having an exterior skin 21 and an interior skin 22 (FIG. 3). The
skins may be plywood or other satisfactory sheeting material.
Similarly the edge members 18 include a plurality of studs 23,
which are fixed at their lower ends to plate members 24 and 24';
the studs 23 having exterior skins 25 and interior skins 26 secured
thereto.
Extending along the upper corner edges and about the periphery of
the roof component 11, are rub-rails 27 which may be in the form of
steel angle members secured to the wood parts making up the roof
component. As is described in more detail below, laterally
projecting lugs 28 are provided integrally with the rub-rails 27 at
spaced intervals therealong, the lugs preferably having an outer
end portion sloping slightly upward.
Above the upper surface of the exterior skin 21 of the roof
component 11, diagonal roof struts 27' extend between the rub-rails
27 along the sides and ends of the roof component, the horizontal
portion of the rub rails 27 and the struts 27' providing means on
the roof component for carrying another structure thereabove in a
manner described below. Indexing pins or protuberances 29 (FIG. 7)
are fixed to these means and project upwardly therefrom.
At the vertical corners of the roof component, there are provided
protective corner brackets 30 secured to the roof component. The
corner brackets 30 may also be steel angle members which are capped
at their upper ends. The corner brackets have flared lower ends 31
which project below the depending edge members 18, as best seen in
FIG. 2.
The bottom plate member 24 provides a bottom edge surface 32 around
the periphery of the roof component 11. The bottom edge surface has
a keyslot 33 formed therein, which keyslot also runs about the
periphery of the roof component.
The floor component 16 has a floor panel 34 mounted on and secured
to a frame structure 35. The frame structure is preferably of
simple design, including a pair of longitudinal members 36, 36,
which may be I-beams, joined at opposite ends by a transverse steel
tubular member 37. At the ends, the lower flange of the
longitudinal members 36, 36 slopes upwardly at 38 to the tubular
member so that the members may function as a skid frame. The lower
flange is also provided with openings 40 (FIG. 7) adjacent the ends
of the longitudinal members 36, 36, the openings being spaced to
receive protuberances 29 as more fully described below.
The floor panel 34 has the exact outer dimensions as the roof
component 11 and includes joist members 41 on which is secured a
skin or floor boarding 42. The joist members may be carried
directly on the longitudinal members 36, 36 of the frame structure
and are bolted thereto.
The floor panel 34 has rub-rails 43, which may be of the same
configuration as rub-rails 27 extending along the lower corner
edges and about the periphery of the floor panel. The rub-rails 43
also have laterally projecting lugs 44 which are aligned vertically
with the lugs 28 and have downwardly sloping end portions.
The floor boarding 42 provides a floor surface within the housing
structure, and the upper peripheral portion 45 has a keystrip 46
which extends continuously around the perimeter of the floor panel
34, and as shown in FIG. 5, the keystrip is located and shaped to
be received in keyslot 33 of the roof component when the housing
structure is in the shipping condition.
Wall panels 12, 13, 14 and 15 are of similar construction, and
depending on the required function the wall panels have windows and
doors built therein. Each wall panel includes studs 47 secured
between lower plate members 50, 50' and upper plate member 51 (FIG.
3), and exterior skins 52 and interior skins 53 are fastened to the
studs. The skins may be in the form of any well known sheeting,
panelling or like material having the desired appearance and
structural characteristics.
Each wall panel thus provides an outside surface 54, an inside
surface 55, and end edge surfaces 56 (FIG. 4). The upper plate
member 51 provides an upper edge surface 57 for engagement with the
bottom edge surface 32 of the roof component 11 when the housing
structure is in the erected condition. Extending along the entire
length of the upper edge surface 57 of each wall panel is a
keystrip 60 arranged to be received in the keyslot 33 when surfaces
57 and 32 are in engagement. The lower plate member 50 provides a
bottom edge surface 58 for the wall panel and has keyslot 61
extending therealong for reception of keystrips 46 of the floor
component when bottom surface 58 engages upper peripheral portion
45 of the floor panel.
When the housing structure is in an erected condition the roof
component 11 is fastened to the floor component with the wall
panels clamped therebetween by way of a tie-down means 62. The
tie-down means 62 includes a plurality of members each having a
device of adjustable length, such as a turnbuckle 63, connected in
end-to-end relation with an elongated element, such as a cable
member 64. At opposite ends the turnbuckle 63 and cable member 64
provide eyes or similar means for reception of vertically aligned
lugs 28 and 44. Thus after each tie-down means is connected between
the lugs, the turnbuckle may be tightened to hold the components in
the erected condition, and the tie-down means is maintained taut
until it is desired to dismantle the housing structure (FIG. 3).
After the housing structure is dismantled, a removable pin 65 or a
similar means may be displaced to permit the cable member 64 to be
dismantled from the turnbuckle 63 which may be connected between
the same lugs of the roof and floor components but with the wall
panels removed so as to secure these components in a shipping
condition (FIG. 5). The length of the turnbuckle is preferably
selected so that it satisfactorily spans the distance between lugs
28 and 49 when the roof component 11 rests directly on floor
component 16 and may be tightened to firmly secure the roof
component in place on the floor component.
The wall panels 12, 13, 14 and 15 are slightly shorter in length
than the outer dimensions of the floor and roof components. For
example, front and back wall panels 12 and 14 are shorter than the
length of the floor and roof components by a few inches, and the
end wall panels 13 and 15 are shorter by a few inches than the
width of the floor and roof components. Thus the end edge surfaces
56 of adjacent wall panels are spaced at the vertical corners of
the housing structure as shown in FIG. 4. The wall panels are held
together, however, by corner brackets 66 each of which includes an
inside angle member 67 and an outside angle member 68. The inside
angle member 67 is an angle iron defining flanges or leg portions
70, 70 disposed at right angles and having outside surfaces 71, 71
for engagement with the inside surfaces 55 of the wall panels. The
outside angle member is also an angle iron defining leg portions
72, 72 disposed at right angles and preferably joined by a flat
angled middle portion 73. The leg portions 72, 72 have inside
surfaces 74, 74, for engaging the outside surfaces 54, 54 adjacent
the vertical corners of the housing structure. The inside surfaces
74,74 have locating stops 75 secured thereto, the stops 75 being in
the form of a small angle iron welded or otherwise secured to the
inner surfaces of the outside angle member so as to project from
the inside surfaces 74, 74 and to provide an abutment for
engagement with the end edge surfaces 56. Bolt means are provided
for securing the inside and outside angle members together and
thereby clamping adjacent walls together at the vertical corners of
the housing structure, the bolt means being in the form of a
plurality of bolts 76 passing through aligned holes in the inside
and outside angle members. The bolts 76 have heads engageable with
the angled middle portion 73 of the outside angle member and pass
inwardly through the corner bracket 66. The inner ends of the bolts
are threaded and are screwed into a nut section 77 secured to an
inner corner bolt adapter 78 which engages the inner side of inside
angle member 67.
When it is desired to complex two or more of the housing structures
10 together, the housing structures are erected side-by-side. The
adjacent walls of the structure are slightly spaced in parallel
relation (FIGS. 8 and 9). In order to provide a door opening
between the structures, the wall of each structure is formed by a
pair of stub wall panels 80, the total length of the pair of stub
wall panels being less than a regular wall panel 12 or 14. The pair
of stub wall panels are spaced longitudinally so that an opening is
formed therebetween. The opening thus formed in the wall of one
structure is aligned with the same type of opening in the adjacent
structure. Cover strips 81, such as sheets of plywood are then
secured to the stub wall panels so as to span the space between the
adjacent walls and thereby frame in the sides of the door opening.
A cover strip 82 is also secured to the bottom edge surfaces 32 of
the adjacent depending edge members 18 of the two housing
structures to frame in the top of the door opening. A preformed
metal threshold member 83 is placed on the floor panels 34 of the
adjacent structures to span the space between the floor components,
the threshold member overlying the keystrips 46 extending along the
upper peripheral portions 45 of the housing structures. A strip 84,
which may be in the form of a heavy tape is secured on top of the
horizontal portions of the rub-rails along the upper corner edges
so as to seal off the space at the roof line of the two housing
structures.
It is believed readily apparent from the above description that the
housing structure 10 of the present invention is one which may be
readily transported, erected and dismantled for shipment to another
site where it may again be erected. In a package or shipping
condition, the housing structure is completely self-contained and
in a form which may be easily handled. As shown in FIG. 5, the roof
component 11 is tightly secured to the floor component 16 by
turnbuckle 63 of the tie-down means 61. Due to the strength
provided by the box beam structure of the roof component 11, the
structure is entirely capable of supporting its own weight plus
others stacked thereon even though the frame structure 35 is of
light and simple construction.
When preparing the housing structure 10 for shipment the wall
panels 12, 13, 14 and 15 are laid one above the other, and even the
front and back wall panels 12 and 14 are contained entirely within
the upper peripheral portion 45 of the floor panel since the wall
panels are slightly shorter than the full length of floor component
11, as described above. The roof component 11 is then placed over
the wall panels, and the bottom edge surface 32 rests on upper
peripheral portion 45 of the floor component with the keystrips 46
being received in the keyslot 33. The turnbuckles are then
connected between aligned lugs 28 and 44 and tightened to tightly
secure the roof component 11 to the floor component 16. The upper
and lower corner edges of the shipping package are protected by the
rub-rails 27 and 43. The vertical corners are protected by the
corner brackets 30. The corner brackets 30 extend from the upper
surface of the roof component 11 along the vertical height of the
roof component and then project below a distance equal to the depth
of the floor panel 34 so as to also protect its corner. Thus, in
addition to forming a rigid self-contained package, it may be seen
that with various means for providing protection to the housing
structure in the shipping condition, special care need not be given
to avoid damage and crushing during shipment. The interior of the
package including the wall panels, are well protected from poor
exterior conditions during shipment since it is well sealed by the
keystrip and keystrip combination which also resists shifting of
the roof and floor components.
Several housing structures 10 may be stacked together or
illustrated in FIGS. 6 and 7 without the use of a shipping
framework or supporting structures carried externally of the
housing structure. The frame structure 35 of one structure is
placed directly on the roof component 11 of another structure, and
it may be quickly and accurately located by the reception of
protuberances 29 in openings 40. After a plurality of structures
have been stacked as indicated in FIG. 6, the structure may be
secured together by means such as steel strapping to form a
shipping unit of several housing structures.
When the housing structure is being erect on site, the turnbuckles
63 are removed, the roof component 11 raised, and the walls put in
their vertical positions. The walls are accurately located by the
reception of the keystrips 46 in the keyslot 61 and by engagement
of the end edge surfaces 56 with locating stops 75 of the corner
brackets 66. Once the corner brackets have been secured to the wall
panels, the roof component 11 is lowered onto the walls and
keystrip 60 is received in keyslot 33 as bottom edge surface 32
comes into engagement with upper edge surfaces 57 of the wall
panels. Cable members 64 are then joined to turnbuckles 63 to form
the tie-down means 62 which are tightened between aligned lugs 28
and 44 on the roof and floor components.
The erected housing structure 10 is highly resistant to weather
conditions since the components are tightly secured together by the
tie-down means 62. The surfaces 32 and 57 and surface 58 and 45 are
held in tight engagement by the tie-down means to form
weather-resistant joints in combination with the reception of
keystrips in the keyslots. The corners are also well sealed by the
corner brackets 66. Moreover, the flared lower ends 31 of the
protective corner brackets 30 overlap the upper ends of the corner
brackets 66.
As pointed out above, the longitudinal members 36, 36 together with
tubular member 37 provide a skid frame so that even the erected
housing structure may be towed short distances. As in the case of
the structure in the shipping condition, all edges are protected by
rub-rails or corner brackets so that the structure is not easily
damaged.
To dismantle the erected housing structure 10, the tie-down means
are dismantled, the roof component raised, and the corner brackets
are removed so that the wall panels may be laid upon the floor
component. Regardless of the number of times the housing structure
is erected and dismantled, all components are left in useable
condition. Even the end portion of the wall panels are undamaged by
repeated dismantling since the corner structures require no nails
or drill holes for bolts or screws.
Very little additional supplies are required to complex two or more
housing structures together. The single wall panel normally used is
replaced by a pair of stub panels 80 as to allow for a door opening
as is described above. The extra strips used to frame the door, the
threshold member and the top cover strip are, of course, only minor
items easily provided within the package as prepared for
shipping.
The above illustrates a preformed embodiment of the invention, it
being readily apparent to one skilled in the art that various
modifications are possible without departing from the spirit of the
invention as defined in the appending claims.
