GENERAL DESCRIPTION OF THE INVENTION
The invention is a series of components which have been carefully
engineered in various sizes and shapes which, when assembled and erected,
can create a very desirable residence and dwelling place for members of
the human race. The components are designed to be manufactured in a
factory and taken to the erection location where the actual erection of
the components involves only a fraction of the time and labor needed for
ordinary, standard construction, and requires no consideration for weather
conditions at the time of said erection. The components are capable of
being placed in varying arrangements so as to provide buildings of
different sizes and shapes, and thereby vary the architecture while still
maintaining the unique advantages which each component offers.
Because of the fact that the outside-to-inside contact has been kept to a
minimum, it is expected that the cost of heating and cooling these
buildings can be reduced substantially over that of ordinary construction.
It is expected that the buildings are virtually both fireproof and free of
all ordinary maintenance, such as painting, roofing, etc. It can be made
of reinforced concrete, which can be surface-sealed at the factory against
the weather and will remain maintenance-free for an extended period of
time. Its capacity to insulate is uniquely different and, therefore,
provides the option of either above-ground or below-ground residences.

DETAILED DESCRIPTION OF THE DRAWINGS
Now, with more particular reference to the drawings, the embodiment of a
house is shown in FIG. 1. The house has a front door 2, a picture window
3, a conventional window 4, a garage 5, a foundation 6, and a flat roof 7.
The house is constructed of modules, preferably of reinforced concrete. The
foundation and below-grade walls 6 of the house 1 are made up of
below-grade hollow concrete air cells used as foundation modules 10 which
act as both the footers and support wall in the excavation for the
residence. The house 1 need not necessarily have a conventional concrete
footer resting on virgin soil because this below-grade module has extended
feet or flanges 11 which are cast on the bottom integrally with the wall
and which distribute the building's weight over the gravel that is spread
on the soil in the excavation and which is non-compressible at the loading
which will be encountered; and also because the extended plate 60
distributes the load of the above-grade wall air cells of the house over
several foundation cells at one time. The below-grade foundation modules
10 come in varying heights to allow either a full basement, a crawl space,
or an on-grade concrete slab, thereby gaining architectural versatility.
The interior floor 15 of the hollow below-grade foundation modules 10 (FIG.
3) slopes toward its own outside wall. Weep holes 12 are cast into the
outside wall so that any moisture seeping into the hollow 13 will be
removed to the outside. Diversionary weep channels 14 are cast into the
outside of the end walls of each foundation module 10 (FIG. 2) in a
downward and outward fashion to divert any water attempting to get through
between the wall castings.
One of the unique points of the foundation module 10 (FIG. 2 & 3) is its
size, which may conveniently be roughly four feet by eight feet by one
foot, having a hollow 13 which may be filled with insulating material and
which is defined by sides and ends and an open top and a closed bottom
with an outwardly, downwardly sloping interior floor 15 and drainage holes
12 and outwardly directed flanges 11. The foundation module 10 also has
inner pressure panels 16 (FIG. 3) resting on shoulders 17 to resist and
transfer the pressure bearing against the unit. The modules are erected by
crane and require no consideration for weather conditions during their
placement. The foundation module 10 could be placed on a conventional
footer if it were to be used in conditions where the ground was swampy or
unstable and would not support the weight of the building. It also might
require an additional concrete footer if the house or residence has
sufficient stories to increase the bearing-load-per-square-inch beyond the
design capacity of the unit. This, however, is not contemplated as a
requirement in residences of two stories or less.
The plate 60 (FIG. 8) is erected on top of the below-grade foundation
module 10 and has the unique property of serving as a second foundation by
distributing the weight of the building over several of the below-grade
concrete wall air cells 10 and automatically self-aligns them by receiving
them into its channel-like casting made up of flanges 61 and 62 which are
connected by a web 63. The slots 64 are for receiving floor joists. These
slots may be of a conventional spacing such as, for example, 16 inches.
The plate 60 is designed to receive either two-inch by ten-inch floor
joists in slots 64 which have been engineered and precast to receive them;
or it will also receive steel trusses in slots which have been engineered
and precast to receive them. Concrete decking of either precast or
poured-in-place construction may also be placed directly on top of the
plate 60. The flange 62 makes up an overhanging exterior edge 65 and
further provides a foundation shelf upon which an exterior surface, such
as brick or stone, can be safely erected.
The above grade air-cell wall foundation module 20 (FIG. 4) like 10, is
designed to give the building a "thermos bottle" effect by eliminating as
much as possible the contact between the inside air and the outside
elements. The wall module 20 may also be made in an approximate size of
four feet by eight feet by one foot, but modifications permit this to be
made in varying heights and widths to meet the requirements of the
architecture of the individual building. Being hollow, they provide
approximately eight inches of tunnel-like cavity 13' which may be filled
with an insulation such as polyurethane foam, wood fibre, or other types
of suitable material which will assist in attaining the desired insulating
effect; or it may be filled with large stones to serve as the reservoir
for a solar collector.
The outside or exposed surface of wall module 20 may be cast in various
appearances, such as by way of example but not limited to, lap siding,
shingles, shakes, split rock, brick, barnboard, log cabin, etc., all of
which are cast as a part of the surface through the use of already
existing form liner inserts which create these appearances. Various
exposed aggregates may also be used.
The closure 30 shown in FIG. 5 has a reduced size side 33 which is
engineered to fit into the cavity 13' of the wall module 20, and an
outwardly peripherally directed flange 32 designed to overlie the ends of
the wall module 20. The closure 30 is used at any place that a window or
door is to be set into a wall, or otherwise the wall needs to be
terminated. The closure 30 will support and anchor a window or door in
position and provides an adequate support for lintels 40 where needed, and
is adapted to fit into the open downwardly-facing side of the lintel for
greater anchoring stability and to provide a more finished appearance to
the building. Like other components, the closure panel comes in varying
heights to suit the particular architecture of the building. Closure
panels are shown in FIG. 1 at the garage 30 and at the door and window
section 30'.
The header or lintel 40 (FIG. 6) may also be used as a threshold and,
consequently, is utilized in various positions to suit the need for a
load-bearing member in the architecture of the home. It consists of two
flanges 41 and 42, and a web 43 connecting the flanges.
Over the entire above-ground wall section, the plate 50 (FIG. 7) is used to
provide alignment of the cells 20 and the lintels 40 and to act as the
support for the roofing system. This plate performs the same function of
alignment as the plate 60 in FIG. 8 except that it does not provide joist
slots, and, therefore, it is contemplated that if the plate 50 is used
between floors or atop the below-grade wall cells 10 that a system such as
precast or poured-in-place flooring would be used. The plate 50 also
serves as window sills or as a low-profile threshold and, consequently, is
used in various positions to suit the architecture of the building.
FIG. 9 shows the recommended foundation detail of a residence utilizing the
foundation module 10. The cross-section reveals an original grade 100
which has been excavated 101. Into the excavation is placed a drain pipe
105 and a sub-footer of non-compressible gravel 104, onto which is set the
basement cell 10. For immediate backfill, a floor 106 such as precast
concrete is set on the foot or flange 11 of the basement cell 10 to resist
the backfill pressures at the base of the foundation unit 10, and
alignment plate 60 (although 50 could be used) is installed. The floor
joists are placed in position in their slots 64 and the backfill of gravel
103 and earth 102 is completed before the excavation becomes frozen or it
rains.
It is not necessary to "tie" the wall modules 10 together because they are
held in position at the bottom by the floor which holds the wall against
any backfill pressure, and at the top by the aligning plate upon which the
building rests. The crack between the wall cell modules does not require a
water-tight seal because a unique feature of the cell is its end walls.
These have diversionary weep channels 14 (FIG. 2) cast in an outward and
downward slanting position. Any moisture which would attempt to pass
through the wall is picked up by the channels and by gravity is diverted
downward and outward to the gravel backfill which surrounds the building.
The wall modules 10 may be made weather-tight for above-grade purposes by
insulating or by sealing the units in a number of conventional ways. The
below-grade portion need not be sealed because of the aforementioned
diversionary weep channels, but sealing may be desirable under extreme
conditions.
The house 1' in FIG. 10 shows two embodiments which may be interchanged
with the corresponding parts in FIG. 1 without affecting each other. They
are peaked roof 8 and the crawl space or "on-grade" type foundation 6'.
The foundation member 70 in FIG. 11 is a generally "U" shaped member
designed and engineered to receive the wall cells 20' and 20" directly
into its channel. It consists of two flanges 71 and 72 connected by a web
73. One channel 71 has joist slots 64' cast into it to receive either the
standard wooden joists or steel joists. The web 73 has drainage holes 12'
in it to permit the escape of water.
FIG. 12 shows a wall detail using the foundation modules 70 at each end and
a module 70' at the center of the house for a load-bearing wall. The
member 70' has two legs 71' of equal length to support the joists 107.
Footer detail as shown in FIG. 13 shows the original grade 100 which has
been excavated 101 and partially filled with gravel 104 and a drain 105.
Onto this is placed the foundation unit 70 and the wall cell 20" which has
been modified to provide extra length since it starts below the floor
level shown by the joist 107. Once the wall cell 20" has been set, the
excavation may be filled with more gravel 103 and earth 102.
FIG. 14 shows wall and floor detail. This system is used for placing walls
20, 20' and 20" on basement cells 10 (or, as in multiple-story
construction, on other wall cells) if standard flooring with joists is
being used. It shows the first wall panel 20 with plate 60 atop and
another wall panel 20 above the plate. The plate 60 has received joist 107
and has lip 66 for setting precast or poured-in-place flooring. The lip 65
is for the construction of brick or stone or other facing material is so
desired.
Load-bearing walls can also be obtained as in FIG. 15 by using the
below-grade cell 10 in both the exterior wall locations and also the
center wall location. The plate 60' will have two legs 61' cast full
height with joist slots 64 in both. In this manner, joists 107 can be set
on both sides of the center load-bearing wall and construction continues
as before.
In the exterior walls FIG. 16 are wall cells 20 with an opening between
them for a window or door. The support of the roof is attained by closing
the open portions of the wall with closure panels 30' cast shorter than
standard and spanning the open area with another closure panel 30" onto
the small side of which is set a lintel 40 open side down. The length so
spanned can be more than one cell in width to obtain architectural
versatility. The entire system is then aligned by setting a plate 50 over
the wall.
FIG. 17, the roofing member 80 is cast in varying lengths and widths to
permit use in a broad range of structural sizes. The roofing member
consists of two flanges 81 and 82 connected by the web 83. Flat roofs
(FIG. 1) are merely laid in place as shown in FIG. 20. In sloped roofs 8
(FIG. 10), the members 80 are cast with supports 80A (FIG. 19) to allow
them to sit solidly atop the plate 50 which aligns the wall sections 20
and 20'. Cross-section of FIG. 18 shows the roof sections 80 and 40"
alternating in position so as to obtain an appealing effect. The panels 80
and 40" could also be cast the same width so as to cover a larger area
more quickly and with fewer units.
Other uses to which the components can be put are realized when one
considers that the lintel 40, when modified, becomes a ridge cap 40' (FIG.
19) for the peaked roof or, when ganged together side-by-side, makes a
superior garage floor due to its capacity to withstand extreme loads.
Other components can be used as patios, rain troughs, walks, steps, and so
on as to be left to the imagination as the components' versatility and
usefulness indicate.
The foregoing specification sets forth the invention in its preferred,
practical forms, but the structures shown are capable of modification
within a range of equivalents without departing from the invention is to
be understood is broadly novel as is commensurate with the appended
claims.
