English Abstract


The present invention relates to a building panel for forming walls, roofs and
floors in a
building constructed with a frame including an expanded foam plastic core
rectangular in
shape, circular voids extending through the thickness of said core, each of
the plurality of
circular voids spaced apart to receive tension members, a coating applied to
at least one face
providing added rigidity and a frame comprising elongated members having
channels sized
to fit on the end faces of the panels for joining a pair of said building
panels together.

FOAM CORE PANEL AND STUCTURAL MEMBERS
FOR PREFABRICATED BUILDINGS
Field of the Invention
This invention relates to a prefabricated building assembly for low-cost
construction of walls,
roofs, and floors that includes the use of a plurality of prefabricated
building modules made of
panels having a foam plastic core of the desired thickness, with the side
edges of the building
panel having prefabricated channels that engage connectors for joining the
panels together to
form walls, roofs, and floors. Each panel also includes a polymer coating,
corrugated plastic or
wood sheeting on its outsides to provide a finish, structural strength, and
rigidity. Each panel also
includes a plurality of circular bores or voids that extend all the way
through the thickness of the
panel across the width of each panel from side to side, each of the passages
being parallel and
spaced at a predetermined and equal distance apart to accommodate partially
threaded horizontal
steel rods or cables which fasten the modules together to provide rigidity for
the structure.
The modules may be used to construct walls of various sizes provided that the
dimensions of the
channel members vary accordingly. Flange type connectors are inserted at the
bottom of each
channel members to secure the wall units to the floor by fastening means such
as screws. The
channels may be made of plastic or metal.
Plywood or cement floors or foundations are also possible with system. The
building system
may be used vertically for traditional or arch-type buildings and for dome-
type structures. The
exterior of the modules is preferably covered with a waterproof fabric such
vinyl.
Background of the Invention
U.S. Pat. No. 4,194,919 to Hattori, et al., describes a method for increasing
flexural strength of
cement compositions. The flexural strength of hydraulic cement compositions
are increased by
water-soluble epoxy resins.

CA 02643945 2008-11-13
U.S. Pat. No. 5,921,046 to Hammond, et al., provides a plastic foam core for
epoxy cement
concrete. There is no description or discussion to provide a foam core with a
coating of epoxy
resin and plastic pipe as described in Applicant's invention herein.
None of the references cited herein disclose Applicant's building block having
a foam core with
an integral vertical plastic or metal channel members nor provide a low-cost
lightweight
construction block that includes preformed voids for horizontal steel rods and
a low-cost
permanent coating that prevents lateral buckling.
Summary of the Invention
A prefabricated building assembly for constructing walls, roofs, and floors,
comprising a
prefabricated building panel made up of substantially a foam plastic core..
Each of the building
panels has horizontal spaced circular voids to receive threaded steel rods or
cables .
The side face of the building panel is received in a channel member. The
purpose of these
channel members is to provide connection between adjacent panels when joined
together, such
that a channel member disposed there between provides alignment and connection
of adjacent
panels.
The building panel includes an epoxy or acrylic resin coating, corrugated
plastic board or
plywood on its side walls to provide strength and a finished surface on the
plastic foam core of
the building panel. The connector system, which includes a plurality of
elongated channel
members, which are also made of plastic or metal The basic foam panel is also
coated with the
epoxy or acrylic resin. The coating is also used as adhesive along the
connectors and wall
interface.
The building panel also includes a plurality of small passageways, both
horizontally and
vertically disposed, for electrical wiring, the passageways being
approximately 3/4 in. in
diameter.

CA 02643945 2008-11-13
The building assembly may be used to construct walls, roofs, and floors. The
building assembly
system described herein can also be used to form roof connections and a
building roof with
supporting trusses.
One of the purposes of the building assembly in the present invention is the
use of styrene or
urethane foam blocks for the construction, that it can be prefabricated in a
factory environment
and then shipped to the building site, so that less manual labor or finishing
is required. The
building assembly in accordance with the present invention has impact and
compressive load
strength. When using the present building assembly, the time of construction
is greatly reduced.
The building panels and assembly connectors are prefabricated in a factory and
come in a
finished condition.
After the footer and slab have been poured, a building panel in accordance
with the present
invention will be placed on top of flange connectors that are secured to the
slab by screws. A
roof type second building panel will be mounted on top of the first building
panel and will
include cylindrical connectors. Again, the epoxy or acrylic resin coating can
be used for adhering
the cylindrical connectors to the recessed walls of each of the building
blocks, apart in the
building panels, with the channel members progressing vertically up to the top
of the wall. The
same construction technique can be used on roofs, as described in greater
detail below.
The present invention seeks to provide a building panel for forming walls,
roofs and floors in a
building constructed with a frame substantially rectangular in shape, first
and second faces
defined by the ends of said core, the end faces each being rectangular, said
core also including a
plurality of circular voids extending through the thickness of said core
between said first and
second face, each of said plurality of said circular voids being essentially
parallel and each of
said circular voids being spaced apart to receive tension members, a plastic
resin forming a
coating, integrally applied to at least said first face, said coating being
approximately one quarter
inch thick for added rigidity; and the frame comprising rectangular, elongated
members, sized
in radius to fit over said panels s for joining a pair of said building panels
together.

Thc present invention also seeks to provide a panel, whcrein the building
panel foam expanded
plastic core is made of styrene or acr-Vlic. the building panel plastic foam
core is made of uretl-iane
and Nvherein the fi-ame members is made of'plastic.
