WALL FRAMING SYSTEM USING PREFABRICATED PANELS
Abstract
A system for framing the walls of a building structure using
three basic types of prefabricated panels including wall panels,
door panels and window panels. The wall panels are dimensionally
identical one with another. The window and door panels are provided
in a limited number of widths to accommodate a variety of standard
window and door frame structures. Erection of the panels is begun
by securing the window and door panels in place atop an existing
floor structure. The wall spaces between the door and window panels
are then framed by installing wall panels one at a time, cutting
each to length as required. Wall panel scrap is minimized, where
practicable, by using each trimmed-off wall panel portion as the
next-installed framing component.

Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to a system of framing the
walls of a building, and more particularly, to a wall-framing
system employing three basic types of prefabricated framing panels;
namely, door panels, window panels and wall panels.
2. Prior Art
A variety of prefabricated framing systems have been proposed to
facilitate the framing of such building structures as houses,
residential garages, and the like. Most known prefabricated systems
employ panels which are specially tailored to a specific building
plan. This approach results in most, if not all, of the panels
being different one from another. Such a system has many
disadvantages, including:
1. The manufacture of the unit is expensive because the variation
in panel construction and sizes:
A. prevents true production efficiencies that can only be achieved
by repetitively producing identical panels;
B. requires substantial engineering and drafting time for each
building;
C. necessitates that all panels be carefully and individually
marked for identification so that each can be installed at its
appropriate location;
D. necessitates that panels be made to order rather than produced
at an optimum time and then stocked for prompt delivery; and,
E. increases the probability of mistakes occurring during
production of the panels.
2. The erection of a building structure is unduly costly
because:
A. time is lost in searching for panels so they can be erected in
the appropriate sequence;
B. where the differences between some of the panels are small, or
if there has been an error in marking, the panels can easily be
confused and improperly installed during construction. Once an
improper panel has been put in position, it is often difficult and
expensive to fully correct the mistake which may, by the time of
its discovery, already have resulted in the cumulative dimensional
displacement of several subsequently-positioned wall panels.
C. if a panel is damaged in transit, or at the construction site,
expensive delays can occur while a replacement panel is
fabricated.
D. many specialized wall panels are heavy and typically require the
use of a crane in order to position the panels. The need for a
crane and a crane operator increases the expense of installation of
the panels. The complexities involved in interconnecting the panel
portions similarly serve to increase the level of skill required
for panel installation.
SUMMARY OF THE INVENTION
The present invention overcomes the foregoing and other drawbacks
and provides an extremely simple, prefabricated-panel framing
system employing lightweight panels which are easily positioned and
installed by two workmen. The construction of a building according
to the present invention requires only minimal skills for proper
installation.
Three types of panel structures are used; namely, door, window and
wall panels. The wall panels are dimensionally identical one with
another and are accordingly completely interchangeable. The window
and door panels vary in width in accordance with the width of the
window and door openings they define, each of these panels being
essentially as narrow as the required opening-defining framework
will permit. By providing a limited number of the dimensionally
different window and door panels, the problems attendant the use of
highly-specialized panel designs are obviated while still
permitting a wide variety of window and door structures to be used
in the resulting building.
Spaced studs defining the widths of the door and window panels are
preferably received between and secured to top and bottom plates of
an adjoining wall panel portion. This overlapping of wall panel
plates with window and door panel studs facilitates the formation
of rigid panel connections.
In framing a building structure such as a home or residential
garage, the three types of panels are used with a minimum of panel
waste. After the wall, window and door panels have been fabricated,
the window and door panels are secured in place on a floor
structure. The spaces between adjacent window and door panels are
then framed with wall panels. The wall panels are cut to length, as
required. Wall panel scrap is minimized by framing the wall area on
one side of a window or door panel with one part of a cut panel and
by using the other part on the other side of the window or door
panel.
Framing the spaces between the upstanding door and window panels is
ordinarily begun by positioning a first wall panel with one end
forming a corner of the building structure. If the distance from
this corner to the first door or window panel is less than the
length of the first wall panel, the first wall panel is cut to
length. If the distance from the corner to the first door or window
panel is greater than the length of the first wall panel, the first
wall panel is simply nailed in place. One or more additional wall
panels are then positioned in the space between the first wall
panel and the first door or window panel, as required, to form a
continuous wall structure. The last of the panels to fill this
space is then cut, as required, and the cut-off wall panel portion
used to continue the framing process on the opposite side of the
first window or door panel.
This framing process is continued around the entire exterior wall
of the building structure. The only scrap which need remain at the
completion of the wall framing process is the remaining cut-off
portion of the last-installed wall panel. All the other wall panel
scraps have been used in the framing process. Even this remaining
panel portion need not be wasted as it can be taken to the next job
and used there.
Interior walls are erected in a similar fashion using a combination
of wall panels which preferably have no exterior sheathing,
together with door panels. The cut-off wall panel portion remaining
from the framing of one interior wall is used in the initial
framing of the next interior wall.
The framing system of the present invention features many
advantages, including:
1. The panels are all of standard size, obviating the customary
practice of providing special panels for each house design, and the
attendant problems of damage in shipment and improper
identification prior to installation.
2. The panels can be jig-made by machine, thereby minimizing labor
costs and assuring that the panels are square and
interchangeable.
3. The panels are light in weight and can easily be positioned and
secured in place by two workmen. No crane or other lifting
mechanism is needed.
4. Waste is limited to some fraction of one standard external and
one standard internal wall panel. These "waste" panels can be taken
to the next job and used in toto, thereby essentially eliminating
panel waste.
Accordingly, it is a principal object of the present invention to
provide a novel and improved building and method of building
construction.
Other objects and a full understanding of the invention may be had
by referring to the following description and claims taken in
conjunction with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIG. 1, the three basic types of panels used in the
framing system of the present invention are illustrated at 10, 11,
12.
The panel 10 is a wall panel and includes top and bottom plates 13,
14. A plurality of spaced studs 15, extend between and are
connected to the top and bottom plates 13, 14. In the preferred
embodiment, the plates 13, 14 and the studs 15 are two-by-fours
such as are ordinarily used in the framing of a home. The plates
13, 14 are typically 8 feet in length. Since standard two-by-fours
are now actually 11/2 inches by 31/2 inches, and studs 15 are
preferably of 7 feet, 9 inches in length to produce a panel which
is 8 feet square.
If the wall panel 10 is to be used in framing the exterior wall of
a building structure, the exterior surface of the panel is covered
with a sheathing material 16. The sheathing material 16 preferably
comprises a lightweight sandwich including such materials as
cardboard and aluminum foil. Such material minimizes the weight of
the sandwich while maximizing its strength and rigidity as well as
thermo-insulating and vapor barrier characteristics. The preferred
currently-available sheathing material is sold under the trademark
"THERMO-PLY" by Simplex Industries, Inc., Adrian, Michigan.
The panel 11 is a door panel and includes a pair of spaced
upstanding two-by-four studs 21, 22. A framework, including a pair
of two-by-four jacks 23, 24 and a two-by-twelve header 25 is
interposed between and connected to the studs 21, 22. This
framework defines a door opening generally indicated by the numeral
26 of such size as will accommodate a standard door structure. A
two-by-four plate 27 is nailed in place along the top of the header
25.
The panel 12 is a window panel and includes a pair of spaced,
upstanding two-by-four studs 31, 32. A window-defining framework is
interposed between and connected to the studs 31, 32 to define a
window opening 33 of such size as will accommodate a selected
standard window structure. The window-defining framework includes a
pair of two-by-four jacks 34, 35 which support a two-by-twelve
header 36. A two-by-four top plate 37 is nailed along the top
surface of the header 36. A two-by-four bottom plate 38 underlies
and is nailed to the bottom ends of the jacks 34, 35. A two-by-four
sill 39 extends horizontally between the jacks 34, 35.
A two-by-four crippler 40 extends vertically between the bottom
plate 38 and the sill 39. A sheathing panel 41 is secured to the
exterior surface of the window panel 12 in the region defined by
the bottom plate 38, the sill 39 and such portions of the jacks 34,
35 as extend between the bottom plate 38 and the sill 39. The
sheathing panel 41 is of the same construction as the sheathing
panel 16.
The window and door panels 11, 12 can be constructed to define door
and window openings 26, 33 of a variety of sizes to accommodate a
variety of different standard door and window assemblies. Two
typical variations of the window panels 12 are shown at 12a and 12b
in FIG. 2.
Referring to FIG. 2, the initial steps of framing a building
structure is shown. Beginning with a floor deck 45 which has been
carefully constructed so that it is square, level and flat, lines
to locate panels of interior and exterior walls are chalked on the
floor. All door and window panels 11, 12 are located and their
centers are marked on the floor deck 45. The door and window panels
11, 12 are then positioned and nailed in place on the floor deck
with nails 46. A brace 47 is secured at the floor deck and to the
door or window panel being installed to hold this panel in position
until the adjoining wall structure has been framed.
Referring to FIG. 3, the installation of exterior wall panels 10 is
illustrated schematically. A first wall panel 10a is cut to length
along a line 47 such that the panel 10a can be positioned to extend
from a corner 50 (FIG. 2) of the floor deck 45 to one side of the
window panel 12a. The position of the cutting line 47 is chosen
such that the top plate 13a and the bottom plate 13b of the panel
10a will overlap the ends of the window panel stud 21a. The panel
10a is positioned in the space between the corner 50 and the window
panel 12a and nailed to the floor deck 45.
One feature of the framing system of the present invention is that
only a straight-line panel cut is required to establish an
overlapping-type connection between the cut wall panels and the
adjoining window and door panels. The trimmed-off top and bottom
plates 13, 14 of the wall panels, as well as sheathing 16, overlap
the upstanding studs of the window and door panels.
Wall-panel waste is minimized by using the cut-off portion 10b of
the panel 10a to continue the framing of the exterior wall on the
opposite side of the window panel 12a. As is shown in FIG. 3, no
additional trimming is required before the panel 10b can be
positioned in abutting relationship to the window panel 12a and
secured to the floor deck 45.
The wall-framing procedure continues, using a second wall panel 10c
which is cut along the line 48 as required to fill the space end of
the panel 10b and a door panel 11a. The cut-off portion of 10d of
the panel 10c is then used to frame the wall region on the opposite
side of the door panel 11a. This framing procedure proceeds around
the entire perimeter of the house.
Before any of the wall panels are nailed to the floor deck 45, they
are driven tightly together at their joints and are checked with a
level to assure that the various window and door openings are
plumb. If, during the cutting and fitting of the wall panels, it
becomes necessary to cut a wall panel at a location occupied by a
stud, the stud is removed and retained for use as required in other
framing procedures.
Referring to FIG. 4, a typical corner juncture is shown between two
wall panels 10a, 10e. Assuming the panel 10a to have been the first
to be installed on the floor deck 45, the corner juncture is formed
by abutting the end of the panel 10e against the end stud 15a of
the panel 10a with the outer surface of the sheathing panel 16e
flush with the outer surface of the end stud 15a. Where the panel
10e must be cut to length, the end stud 15e shown in FIG. 4
represents a stud which has been added to the panel 10e along the
line of cut before the panel 10e has been erected.
A two-by-six 54 is then positioned in abutting relationship with
both the end stud 15a of the panel 10a and the end stud 15e of the
panel 103, and nailed in place to secure the corner connection.
Referring to FIG. 5, the initial step of framing an interior wall
is illustrated. Interior walls are framed using a combination of
interior wall panels 110 and the door panels 11. The interior wall
panels 110 essentially differ from the exterior wall panels 10 only
in that the sheathing material 16 is preferably omitted from the
interior wall panels, although suitable sheathing may be used.
Starting at one end of the exterior wall panels 10, an interior
wall panel 110 is positioned in place at a predetermined location
on the floor deck 45 with one end of the panel 110 abutting the top
and bottom plates 13, 14 of the panel 10. The panel 110 is then
nailed to the floor deck 45 and to the top and bottom plates 13,
14. A plurality of bridging blocks 55 are then installed between
the exterior wall panel studs 15 which are nearest to the end of
the panel 110, and the end of the wall panel 110 is nailed to the
bridging blocks 55.
When all the panels, both exterior and interior, have been erected
and nailed in their final position, a second top plate is nailed
atop the top plates of all the panels in such fashion as will
bridge the junctures between the panel top plates and thereby
strengthen the framed walls.
Referring to FIG. 6, top plate two-by-fours 60, 61, 62 are shown
nailed in place to strengthen the juncture between an exterior wall
and interior wall. The bridging of wall panel junctures by the top
plates is illustrated in that the top plate 62 bridges the juncture
between interior wall top plates 13a, 13b, and also overlaps the
exterior wall panel top plate 13.
As will be apparent from the foregoing description, the present
invention provides an extremely simple system for framing the
exterior and interior walls of a building structure using only
three basic types of light-weight framing panels. The only cutting
and fitting required in the framing process is a simple,
straight-line cut employed in cutting the wall panels to length.
Wall panel waste is minimized by framing the region on one side of
a window or door panel, where practicable, with the cut-off
portions of the wall panel used to frame the other side of the
window or door panel.
Although the invention has been described in its preferred form
with a certain degree of particularity, it is understood that the
present disclosure of the preferred form had been made only by way
of example and numerous changes in the details of construction and
the combination and arrangement of parts may be resorted to without
departing from the spirit and the scope of the invention as
hereinafter claimed.
