ASSEMBLY OF COLLAPSED BUILDINGS FOR SHIPPING
Abstract
A building made up of a plurality of sections at least one of
which is collapsible for shipping and of which preferably all may
be collapsed if desired or one or more may be shipped erect and
filled with equipment. The roof is provided with a depending skirt,
which in a collapsed condition either overlies the floor or
cooperates with an additional skirt member which extends between
the floor and the roof skirt to exclude water from the shipping
package. When the building is erected, the roof skirt extends down
over the joint between the roof and walls to form a seal there
between. The skirt is of thin material which pulls into an
out-of-the-way position over the interior walls which interior
walls support the roof. Electrical outlets are provided in the
walls with pigtails, which are exposed at the upper end of the
walls through an access panel. A breaker box is provided in the
ceiling and the wires run from the breaker box to the perimeter of
each roof section and thence down through the top plates of the
walls where they are connected to the pigtails running from the
wall outlets.

Description
This invention relates to buildings and more particularly to
portable collapsible buildings which may be collapsed during
shipment and easily erected into finished form with a minimum
amount of assembly.
Portable buildings in which single piece roofs and walls are
designed to be collapsed for shipping and readily erected into a
finished product are well known. (See Bigelow U.S. Pat. No. Re.
25,827.) While these buildings have been arranged and used together
in various manners, they have essentially been individual buildings
positioned together with suitable access between buildings.
Prewired buildings of the type shown in the Bigelow Patent where
the walls are completed, conventionally employ surface mounted and
exposed electrical receptacles and wiring on the walls which is
undesirable. The method taught therein permits production line
manufacturing of prefabricated housing where wiring is concealed in
the walls and ceiling and may be readily joined together with
relatively semi-skilled labor.
It is an object of this invention to provide a portable building
which is moved in sections, at least some of which are designed to
be collapsed for shipping, and which may be easily erected into a
single unitary building with common walls between adjacent
sections.
Another object is to provide a portable building which is
constructed of several sections, at least some of which are adapted
to be collapsed for shipping, in which the wiring of the building
is totally concealed, giving the appearance of a home fabricated on
the site; and in which the building is prewired before
shipping.
Another object is to provide a building composed of sections in
which some sections may be collapsed for shipping; and in which the
skirt depends from the roof and may engage with the floor or with a
disposable piece which depends to the floor to protect the interior
of the package during shipping; and in which the skirt corporates
with the outer wall of the building to provide a seal between the
roof and wall; and in which the skirt may be moved to an
out-of-the-way position over interior walls where it will not
interfere with support of roof sections by interior walls.
Another object is to provide a concealed lifting eye for a
roof.
Other objects, features, and advantages of the invention will be
apparent from the drawings, the specification, and the claims.
In the drawings wherein an illustrative embodiment of this
invention is shown and wherein like reference numerals indicate
like parts;
FIG. 1 is an isometric view of four building sections with one
section in erected condition and the remaining sections in
collapsed condition for shipping, illustrating the manner in which
the collapsed sections may be stacked, one upon the other;
FIG. 2 is an isometric view of the building when completely
erected;
FIG. 3 is a cross sectional view through a portion of the building
illustrating the manner in which the building is wired and the
manner in which building sections are connected together;
FIG. 4 is a fragmentary sectional view through an interior wall
supporting adjacent roof sections illustrating the manner in which
the wiring is handled for electrical outlets on interior walls;
FIG. 5 is a top plan view of the roof of the building with the top
sheathing removed to expose the ceiling and with interior walls
shown in dashed lines and illustrating the manner in which the roof
sections are prewired;
FIG. 6 is an elevational view of an exterior wall of the building
with the internal wall covering removed;
FIG. 7 is a view on an enlarged scale of a fragment of the building
showing the manner in which end walls of the building sections are
tied together and the manner in which the roof sections are tied
together and a seal provided between adjacent roof sections;
FIG. 8 is a fragmentary view in sections through a collapsed
building section illustrating the manner in which the building is
sealed against entry of water during shipping; and
FIG. 9 is a fragmentary isometric view of a section of a roof to be
positioned over an interior wall showing the suspension strap for
attachment to a lifting cable.
Referring first to FIGS. 1 and 2, the building is shown in erected
form in FIG. 2 to comprise the four sections 11, 12, 13, and 14. If
desired, a carport 10 may be added.
The building may be shipped completely equipped with kitchen, bath,
and laundry facilities, as well as furniture if desired. In this
event, one section 14 would normally be shipped in erected form and
all of the furniture would be packed therein. Preferably all
utilities are preinstalled at the factory in this section 14. The
section 14 may be fully erected with an outside wall from one of
the other sections, but it is preferred that the wall indicated
generally at 15 be a temporary wall for shipping purposes. The
temporary wall might be provided by any desired construction, such
as a continuous sheet of plastic material overlaid with sections of
plywood 15a. In this manner, the necessity of dismantling one side
wall is avoided.
The remaining sections are shipped knocked down as shown in FIG. 1.
Sections 12 and 13 are shown in stacked relationship, one upon the
other. Section 11 is shown ready to be stacked on section 13.
During shipping, section 11 would be supported on the stacking
racks 16 of section 13 in the manner taught by the aforesaid
Bigelow patent. These stacking racks would be temporarily supported
on the skid and would be removed during erection of the
building.
The plan of the building is shown in FIG. 5. The areas 16, 17, and
18 are open to each other and provide a living room. The areas 19,
20, and 21 are three bedrooms. In area 22, the kitchen is provided.
Area 23 is the utility room and areas 24 and 25 are two baths. It
will be noted that the bath 25 is associated with bedroom 21 to
give a private bath for one bedroom.
FIG. 5 also illustrates the manner in which the wiring for the
building is handled in the roof sections. Referring to section 14,
the main line power line for the building enters through box 26 and
a lead to the other building sections is provided in conduit 27
which passes through junction boxes 28, 29, and 30 on the building
sections 13, 12, and 11, respectively. A similar junction box 31 is
provided on building 14 and from this box conduit 32 connects to
the breaker box A in the ceiling of building 14. Like breaker boxes
B, C, and D are provided in the other sections. In accordance with
this invention, all wiring for each building section as exemplified
by building 14 is provided by conduit extending from the breaker
boxes. These conduits extend to the perimeter of the roof at
desired points as exemplified by conduit 33 and to points for
connection with interior walls as exemplified by wire 34. The
conduits extend downwardly from the ceiling and terminate shortly
therebelow as will be apparent from FIGS. 3 and 4 where the wires
in the conduits are connected to wires in the walls of the
building. Thus, for instance, in FIG. 3 the wall receptacle 35 has
its pair of leads in a common conduit 37 extending upwardly to a
position indicated generally at 38 just below the roof. The conduit
33 extends downwardly through the ceiling 34 of the roof and the
top plate 36 of the wall. As shown in FIG. 3, the two wires within
the conduit 37 are electrically connected to the two wires within
the conduit 33.
The construction of the building and the manner in which the
building sections are ties together is exemplified in FIG. 3. The
building sections are supported on skids made up of suitable
longitudinal I beams 39 and 40 which are tied together at spaced
points with suitable cross beams. A metal pan 41 is laid over the
skid, and floor sills 42, 43, and 44 are secured together and
suitably attached to the skid. A base floor covering, preferably of
plywood, 45 is laid over the floor sills and the base floor
covering is itself covered with a suitable material, such as
linoleum 46.
By reference to FIGS. 3 and 6, it will be seen that each exterior
wall includes studs 47, top plate 36, and lower plate 48. An inner
covering, such as plywood 49, covers the inside of the wall. In
areas in which electrical connections are to be made between
conduits in the roof and in the wall, the inner wall covering 49
will terminate short of the top plate, preferably at a horizontal
stringer 51 as shown in FIG. 3. The remaining inner wall covering
is provided by a removable panel 52 which is nailed in place after
the electrical connections have been completed.
The exterior wall covering is provided preferably by plywood 53
having bonded to the exterior thereof an impervious covering such
as an aluminum 54. This aluminum preferably has a bonded coating of
paint thereon. It will be noted that the exterior covering 53-54
extends downwardly below the bottom plate 48. Preferably, it
extends to the bottom of sill 44 to provide a water-tight covering
over the juncture between the wall and floor and to conceal the
floor sill. The same construction is followed on all of the
peripheral walls.
The construction of the interior walls are shown in FIGS. 3 and 4.
The interior wall consists of an upper plate 55 and a lower plate
56 covered with suitable material such as plywood 57, preferably up
to the level of the stringers 51. Where no electrical connections
are to be made in a particular wall, the covering 57 may be
extended up to the top plate if desired. In the interest of
conformity, it is preferred that the portion of the wall above the
stringers 51 be covered with the removable panel 52, which may be
the same throughout the building. It is pointed out that the panel
52 would also cover the access hole on the exterior wall. In FIG.
4, an interior wall having an electrical conduit 58 therein is
shown, and the removable panel 52 gives access to secure the wires
in the conduit 58 to like wires in the conduit 59 extending down
from the ceiling.
It might be noted that the top plate 55 has a hole 61 cut
approximately in its center to underlie the space between the edges
of contiguous roof sections. A notch 62 is cut in the lower edge of
the longitudinal rafter 63 which may for instance be a 2-by-12. The
notch also extends down through the ceiling board 76 as shown at
64. Thus, the conduit 59 may turn about a relatively gentle radius
and extend downwardly in the space between adjacent roof sections.
While the roof sections are shown to be very close together, it
will be understood that the conduit is disproportionately large in
the drawings and there is room enough for the conduit to extend
downwardly between two adjacent roof sections and into the interior
wall. By contrast, it will be noted from FIG. 3 that the conduit
for the exterior walls extends downwardly through the ceiling 34 at
a point slightly inboard from the longitudinal rafter 65 and
through the hole 66c in the top plate.
One or more of the building sections will be shipped in collapsed
position, as shown in FIGS. 1 and 8. As shown in FIG. 8, the walls
indicated generally at 67 and 68 are stacked on the floor indicated
generally at 69. A plurality of spacers 71 are laid on the
uppermost wall in a position not to interfere with the conduits
depending from the roof section. The roof is then set down on these
spacers with the conduits, such as shown at 72, turnedin and lying
on top of the uppermost wall between the spacers. These spacers may
be short sections of 1-by-2 lumber covered with paper to avoid
marring the finish on the walls and ceiling. It will be noted that
the skirt 66 terminates above the floor. In order to protect the
shipping package, a piece of plywood 73 is secured in position and
extends from the floor upwardly to a position underlying the skirt
66. The skirt may then be temporarily secured to the piece of
plywood 73, and there results a shipping package which will exclude
the elements from the interior of the package. In those instances
where it is desired to ship all of the walls in two of the
collapsed sections, the third section may be made up merely of the
floor and ceiling, and in this instance the skirt 66 would
cooperate with the floor to exclude weather from the interior of
the shipping package.
At the site the roof is lifted from the shipping package and the
several walls stood up and secured in upright position, as shown in
FIG. 3. Where one of the packages is shipped with the equipment
installed, the temporary wall 51 will be removed and the next skid
and floor may be positioned immediately adjacent to the erected
section. Preferably a foundation not shown is provided upon which
the several building sections are erected. The additional sections
may be erected one at a time, or they may be erected with the
exception of the roof until all are erected and then the several
roof sections placed in position. In either event, the skirt 66 on
the outer peripheral of the building will extend down over the
peripheral wall, as shown in FIG. 3, to provide a weather-tight
seal. Where roofs butt each other, the skirt 66a is turned
upwardly, as shown in FIG. 3, to a position where it will not
interfere with the roof resting upon the interior wall. Lag bolts,
such as shown at 74, will tie the upper plate of the walls to the
longitudinal rafter 65 of the roof structure, as shown in FIG. 3,
to hold the roof in position.
It will be noted from FIG. 5 that at the juncture of each pair of
sections of the building at least a short stub wall, such as shown
at 66b, is employed at the peripheral of the building to support
the roof at its corners and to provide a means for securing two
sections of the building together as will appear hereinafter.
The roof is made up of the longitudinal rafters 65 and cross
members 75, extending therebetween together with ceiling board 76
applied to the underside of the roof, and a top board 77 applied to
the upper side of the rafters. An impervious covering 78 is applied
over the top board. When the roof is set in position on the walls,
the ceiling board 76 rests upon the walls.
From FIG. 3 it will be noted that the skirt 66 extends upwardly to
a position where it underlies the top impervious covering 78. This
covering 78 may be aluminum having suitable paint bonded thereto.
It will be appreciated that the covering 78 provides a water-tight
structure for each roof section.
In order to tie the roof sections together, wooden members 75
preferably extend the length of each side of each roof. Thus, when
two roof sections are positioned side by side, the members 75 will
lie parallel to each other. A length of plywood 76 is then placed
over the members 75 and nailed into position to secure the two roof
sections together. Preferably, suitable calking material is placed
between the aluminum skin 78 over the roof and the member 75 before
the members 75 are fastened into place on the roof. An inverted
channel shaped section of impervious material 79, preferably
aluminum having a suitable paint bonded thereto, is then placed
over the plywood 76 and nailed in place with nails passing through
the legs of the channel shaped member into the elongated members
75. Suitable sealing means such as calking material 81 is
positioned between the channel shaped member 79 and the roof cover
78 to seal therebetween. At the ends of the roof the legs of the
channel are cut away and the web 79a is turned down and nailed into
position, as shown in FIG. 7.
The peripheral walls of the building are secured together by
fastening a metal strap 82 to each peripheral wall at spaced
vertical points opposite an interior wall. A lag bolt 83 is then
extended through a hole in the strap 82 into the adjacent stud in
the interior wall to thus provide for securing of the peripheral
walls to the interior walls at the juncture between adjacent
building sections. A strip of material 84, which is the same as the
material providing the outer skin 54 of the building, is then
placed in position to overlie the joint between adjacent buildings
and cover the strap 82. After the material 84 has been placed into
position, the channel 79 has its end portion 79a turned down and
nailed into position, as shown in FIG. 7.
With buildings having roof sections of considerable length, it is
desirable in lifting the roof section to attach to the roof section
at points along its length. On the peripheral of the roof this
presents little problem as a bolt 85 (FIG. 3) may be carried in the
rafter 65 and a strap 86 having an eye 87 therein may be provided
to which a hook can be attached. After the building is erected, the
bolt 85 may be removed and the hole filled with calking compound.
However, this type of arrangement cannot be used where roof
sections are adjacent to each other, as there is no access to a
bolt such as 85. In FIG. 9, there is shown a construction of a
strap which may be raised for lifting, and after the roof is in
place may be lowered into an out-of-the-way position. The rafter 65
has a notch 88 cut in its lower face. A J-shaped strap 89 is
provided with the hook on the J-being shown in dashed lines at 89a
to extend into the notch and when the strap is raised to hook about
the downwardly facing surface of the notch 88 and extend upwardly
about the inside of the rafter 65 so that the strap cannot
disengage from the rafter. The strap has a slot 91 therein, and a
pair of nails or bolts 92 are provided to extend through the slot
and hold the strap in place. A suitable eye 93 is provided at the
upper extremity of the strap to which a lifting hook can be
attached. The strap is shown in its operative position in FIG. 9.
It will be appreciated that after the roof is in position, the
strap is pushed downwardly and at this time the upper end of the
strap will be down to at least the level of the upper surface of
the wooden members 75 on the top of the roof so that the strap will
not interfere with the placement of the sheet of plywood 76
thereover.
The foregoing disclosure and description of the invention are
illustrative and explanatory thereof and various changes in the
size, shape and materials, as well as in the details of the
illustrated construction, may be made without departing from the
spirit of the invention.
