DESCRIPTION OF THE PREFERRED EMBODIMENT AND BEST MODE
Referring now specifically to the drawings, a foldable building according
to the present invention is illustrated in FIG. 1 and shown generally at
reference numeral 10. The building 10 preferably includes insulation 11
and exterior siding 12 (See FIGS. 5 and 6) which is affixed to the
building 10 at a prefabrication site. From the prefabrication site, the
assembled building 10 is transported in a folded condition to a building
erection site. Preferably, a vehicle 13 including a flatbed trailer 14 and
carriage 15 is used for transporting the folded building 10. The carriage
15 is vertically moveable by operation jacks 16 carried on opposite ends
of the trailer 14. After arriving at the building erection site, the
building 10 is unfolded and mounted on a pre-formed concrete foundation
17, as described in detail below.
General Description of Building 10
The building 10, shown in FIGS. 1-13, is constructed of a central roof
section 21, first and second outer roof sections 22 and 23, and first and
second side walls 24 and 25. The central roof section 21 includes
spaced-apart, opposing central roof beams 21A and 21B at opposite ends of
the building 10 which are vertically supported by the carriage 15 during
transport of the building 10, and prior to unfolding and mounting the
building 10 on the concrete foundation 17. The first and second outer roof
sections 22 and 23 include respective pairs of spaced-apart outer roof
beams, 22A, 22B and 23A, 23B, pivotally connected to the beams 21A and 21B
of the central roof section 21. The first and second side walls 24 and 25
include respective pairs of side beams, 24A, 24B and 25A, 25B, pivotally
connected to the beams 22A, 22B and 23A, 23B of the first and second outer
roof sections 22 and 23.
Each of the corresponding, opposing beams 21A&21B, 22A&22B, 23A&23B,
24A&24B, and 25A&25B of the building 10 are interconnected by a plurality
of horizontal joists 26 (See FIG. 13) for carrying the building insulation
11 and exterior siding 12. As is well known by those of skill in the art,
buildings of greater dimensions will require additional beams and joists
to provide the necessary lateral and vertical support for the building.
According to one embodiment, the building 10 has dimensions of 24
ft..times.24 ft. Alternatively, the building 10 may have dimensions such
as 24 ft..times.36 ft., 30 ft..times.36 ft., or 50 ft..times.50 ft.
A hinge assembly 28, 38 (See FIGS. 5 and 6) is located between each of the
adjacent beams 21A&21B, 22A&22B, 23A&23B, 24A&24B, and 25A&25B of the
building 10 to pivotally connect the beams together. The respective hinge
assemblies 28, 38 permit the walls of the building 10 to fold inwardly
during transport, and to unfold outwardly for mounting the building 10
onto the concrete foundation 17.
Transporting the Building 10
As discussed above, the building 10 is preferably fully assembled at a
prefabrication site where exterior siding 12 and insulation 11 is applied
to the walls of the building 10. The completed building 10 is then mounted
on the trailer 14 and carriage 15, and folded for transport to the
building erection site. Folding the building 10 prior to transport permits
relatively easy relocation of buildings of relatively large dimensions,
such as 50 ft..times.50 ft. buildings.
The jacks 16 mounted on the trailer 14 allow vertical adjustment of the
position of the carriage 15 relative to the trailer 14. This permits the
carriage 15 to lift or lower the building 10, as desired. Preferably, the
jacks 16 are standard railroad jacks. Alternatively, the jacks 16 may be
heavy-duty hydraulically actuated cylinders.
When the building 10 is ready for transport, the jacks 16 and carriage 15
elevate the folded building 10 a sufficient distance above the ground. The
trailer 14 is then attached to vehicle 13 which transports the folded
building 10 to the building erection site. At the erection site, the
folded building 10 is centered on the concrete foundation 17, and the
trailer 14 detached from the vehicle 13.
Erecting the Building 10
FIGS. 2 and 3 best illustrate the arrangement of the central roof section
21, outer roof sections 22 and 23, and side walls 24 and 25 prior to
unfolding and mounting the building 10 on the concrete foundation 17. The
carriage 15 of the trailer 14 supports the building 10 above the concrete
foundation 17 prior to and during unfolding.
As shown in phantom in FIG. 3, the central roof section 21 and outer roof
sections 22 and 23 collectively define the roof "R" of the building 10.
The side walls 24 and 25 extend downwardly from the roof "R" to the
concrete foundation 17. Brackets (not shown) located along the base of the
side walls 24 and 25 align and mate with a plurality of anchor pins 29
extending upwardly from the concrete foundation 17. The anchor pins 29
serve to secure the building 10 to the foundation 17.
To erect the building 10, a lifting arm 30 including a winch 31 and hoist
cable 32 is preferably used to lift each of the outer roof sections 22 and
23 into alignment with the central roof section 21. The lifting arm 30 is
removable from the trailer 14, and is preferably stored in the trailer 14
for convenient and easy access. The trailer 14 includes channel brackets
(not shown) located on opposing sides of the trailer 14 for receiving the
connecting end of the lifting arm 30. A block 33 provides vertical support
for the lifting arm 30 as the respective walls of the building 10 are
moved into their erected position. As shown in FIG. 4, the hoist cable 32
is first attached to an edge of the first outer roof section 22, and is
then retracted using the winch 31 to lift the first outer roof section 22
into position.
FIG. 4 illustrates the pivoting movement of the first outer roof section 22
from the lowered position to the raised position in substantial alignment
with the central roof section 21. When properly aligned, the outer roof
beams 22A and 22B of the first outer roof section 22 are coupled,
respectively, with the central roof beams 21A and 21B of the central roof
section 21 by a plurality of threaded bolts and nuts. Alternatively, the
respective outer roof beams 22A and 22B and central roof beams 21A and 21B
may be connected together by welding.
The connection of a single outer roof beam 22A to an adjacent central roof
beam 21A is best shown in FIG. 5. The hinge assembly 28 and connection of
the remaining outer roof beams 22A, 22B, 23A, and 23B to the central roof
beams 21A and 21B are identical to that shown in FIG. 5.
Once the first outer roof section 22 has been secured in the raised
position to the central roof section 21 as described above, the first side
wall 24 is lowered and secured to the first outer roof section 22. The
side beams 24A and 24B of the first side wall 24 and the outer roof beams
22A and 22B of the first outer roof section 22 are connected together,
respectively, by a plurality of threaded bolts "B" and nuts "N".
Alternatively, the respective side beams 24A and 24B and outer roof beams
22A and 22B may be connected together by welding.
FIG. 6 illustrates the connection of a single side beam 24A of the side
walls 24 and 25 to an outer roof beam 22A of the outer roof sections 22
and 23. The hinge assembly 38 and connection of the remaining side beams
24A&24B and 25A&25B to the outer roof beams 22A&22B and 23A&23B are
identical to that shown in FIG. 6.
Referring now to FIGS. 7, 8, and 9, the first half of the building 10 is
shown erected and bolted together as described above, and the lifting arm
30 is shown on the opposite side of the trailer 14 in position to erect
the second half of the building 10. As shown in FIG. 7, the hoist cable 32
is first attached to an edge of the second outer roof section 23. The
second outer roof section 23 is then lifted upwardly into position. FIG. 8
illustrates the pivoting movement of the second outer roof section 23 from
the lowered position to the raised position in alignment with the central
roof section 21. When properly aligned, the outer roof beams 23A and 23B
of the second outer roof section 23 are coupled, respectively, with the
central roof beams 21A and 21B of the central roof section 21 by a
plurality of threaded bolts "B" and nuts "N", or by welding. The
connection of the outer roof beams 23A and 23B of second outer roof
section 23 to the central roof beams 21A and 21B of the central roof
section 21 is identical to that described above with reference to the
first outer roof section 22.
Once the second outer roof section 23 has been secured in the raised
position to the central roof section 21, the second side wall 25 is
lowered into position. The side beams 25A and 25B of the second side wall
25 and the outer roof beams 23A and 23B of the second outer roof section
23 are connected together, respectively, in an identical manner described
above with reference to the first side wall 22.
As shown in FIGS. 9 and 10, the building 10 is now completely erected and
ready for mounting on the concrete foundation 17. The lifting arm 30 is
removed from the trailer 14, and the carriage 15 is lowered by jacks 16 to
place the erected building 10 onto the foundation 17. The brackets (not
shown) on the base of the side walls 24 and 25 are aligned and mated with
the plurality of anchor pins 29 projecting upwardly from the concrete
foundation 17, as shown in FIG. 10. Preferably, bolts connect the brackets
and anchor pins 29 together.
Referring to FIGS. 11, 12, and 13, after the building 10 has been erected
onto the supporting foundation 17 as described above, a separate front
wall 41 and/or back wall 42 may be added to the building 10 for closure.
As shown in FIG. 12, the front wall 41 preferably includes one or more
