Description
BACKGROUND OF THE INVENTION
The present invention relates in general to the construction of the
exterior of a building and more particularly to a prefabrication
panel for the construction of a building exterior.
Continuous effort has been made in the construction of a building
exterior to improve the weather resistant characteristics of a
building exterior. It has, heretofore, been customary to employ
layers of waterproof material, such as tarred felt or the like.
Also, the manner of interlocking and overlapping panels has been
used to improve the weather resistant characteristics of building
exteriors.
Heretofore, strips on prefabricated panels for building exteriors
have been secured across layers of shakes and shingles.
Consequently, such strips did not serve as weather resistant
barriers. Disclosures of such strips can be found in the patent to
Wilde, U.S. Pat No. 2,285,480, issued on June 9, 1942, for
Prefabricated Shingle Panel and the patent to Fink et al. U.S. Pat.
No. Re 24,246, dated Dec. 4, 1956. In the patent to Kough et al.
U.S. Pat. No. 3,509,676, issued on May 5, 1970, there is disclosed
a strip for use as a weather resistant barrier, which is fixed to a
sheathing of a panel to confront the facing material fixed to the
same sheathing for providing a weather resistant barrier.
SUMMARY OF THE INVENTION
A prefabricated panel for the construction of the exterior of a
building in which a panel comprises one or more layers of a
plurality of facing material secured to one surface of a sheathing
and a strip secured to an opposite surface of the sheathing along
the length of the sheathing.
A plurality of such panels are disposed in overlapping relation. In
one embodiment, the strip of the upper panel has one surface
thereof confronting and contiguous to the sheathing of the lower
panel and has another surface thereof confronting the facing
material secured to the sheathing of the lower panel to provide a
weather resistant barrier. In another embodiment, the strip of the
upper panel has one surface thereof perpendicular to the surface of
the sheathing to which it is secured, which surface of the strip
confronts and abuts against the upper edge of the sheathing of the
lower panel to align and guide the location of the overlapping
panels and to provide a weather resistant barrier.
The strip serves to inhibit the seepage of water into the interior
of structures. Thus, a barrier is formed against rain and moisture
being blown into the interior of the structure. Toward this end,
the strip reduces the accumulation of blowback moisture or rain
into the interstices of a building exterior and also under and
between the facing material. In addition to serving as a weather
resistant seal, the strip also serves as a guide in the alignment
and placement of overlapping panels. The lower edge of the upper
panel in the last mentioned embodiment is raised from the rafters
without a long bridge by resting sheathing of an upper panel onto
the sheathing of a lower panel aligning the upper panel relative to
the lower panel through the strip of the upper panel. Consequently,
facing material with rectanguloid configurations as distinguished
from a tapered shingle or shake can optionally be employed and,
yet, a smooth overlap is attained between overlapping panels. It
has been found that rectanguloid facing material is generally
stronger, less expensive and more weather resistant than tapered
facing material. Structurally, an improved building exterior is
realized, since the sheathings are structurally stronger, and
lighter in weight, while the strip lends structural improvements to
the building exterior.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Illustrated in FIGS. 1 and 2 is a panel 10 of the present invention
which comprises a conventional sheathing or base strip 11. In the
exemplary embodiment, the sheathing 11 is made of plywood. Secured
to the sheathing 11 is a plurality or a layer of facing material
14. The facing material 14 may be of one or more layers. In the
exemplary embodiment, the facing material 14 is disposed in
substantially abutting relation in a side-by-side manner. The
facing material 14 may be any suitable surfacing material, such as
shakes, shingles, tile, composition asbestos, veneer, peeler strip,
and the like.
Secured to the sheathing 11 by suitable means, such as nails or
staples, is a strip 15. The strip 15 is secured to a surface of the
sheathing 11 opposite from the surface to which the facing material
14 is secured. Specifically, the facing material 14 is secured to
the surface 11a of the sheathing 11 and the strip 15 is secured to
the surface 11b. The strip 15 which in the exemplary embodiment is
made of wood is disposed along the length of the sheathing 11 in
the vicinity of the lower edge thereof. The lower edge being the
lower edge when the panel 10 is installed as a building exterior.
In a typical embodiment, the strip 15 is of the same length as the
sheathing 11; is 1 inch wide; and has a depth sufficient for the
strip 15 to extend generally the height of facing material (FIG.
4).
Optionally, a membrane, not shown, of suitable material, such as
tarred felt or the like, is secured to the upper surface 11a of the
sheathing 11 between the sheathing 11 and the facing material 14.
The membrane is co-terminal with the ends of the sheathing 11, but
extends upwardly to or above the upper edge of the sheathing 11 and
projects below the lower edge of the sheathing 11 a distance
commensurate with the facing material 14.
For constructing an exterior of a building according to the present
invention, a plurality of adjacent panels similar to panel 10 are
secured to the rafters or the like in a longitudinal overlapping
relation (FIGS. 3-6). Since the panels are similar in construction
and function like parts of the panel adjacent the panel 10 will be
designated with the same reference numeral but with a prime
suffix.
In one embodiment of the present invention (FIGS. 3 and 4), the
panels 10 and 10' are joined in longitudinal overlapping relation
with the strip 15 in even contact with the upper surface of the
sheathing 11' and also in abutting relation with the upper edge of
the facing material 14'. More specifically, the strip 15 of the
upper panel 10 has one surface thereof engaging the surface 11b of
the sheathing 11 to which it is fixed and an opposite surface
parallel with and in even contact with the surface 11a' of the
sheathing 11 of the lower panel 10'. It is understood, of course,
should a membrane be disposed on the sheathing 11', then the strip
15 will be in contact with such membrane. In addition thereto, the
strip 15 has a surface perpendicular to the surface 11b of the
sheathing 11 and the surface 11a' of the sheathing 11', which
confronts the aligned upper edge of the facing material 14' of the
lower panel 10'. Optionally, the strip 15 may abut or be spaced
from the upper edge of the facing material 14'.
From the foregoing, it is to be observed that the strip 15 not only
provides a blowback seal but also serves as a guide in the aligning
of overlapping panels. When the strip 15 engages the sheathing 11',
the upper panel 10 is guided relative to the lower panel 10'.
Should the strip 15 abut against the facing material 14', then the
upper panel 10 will be aligned relative to the lower panel 10'.
With the strip 15 of the upper panel 10 confronting the facing
material 14' of the lower panel 10' and in even contact with the
sheathing 11', or any waterproof membrane thereon, a weather
resistant barrier and a blowback seal is provided. Through this
arrangement, rain or moisture is inhibited from entering the
interstices and from entering under and between the panels and the
building structure and also from penetrating between irregular
surfaces of the facing material.
In another embodiment of the present invention (FIGS. 5 and 6), the
panels 10 and 10' are joined in longitudinal overlapping relation
with the strip 15 of the upper panel 10 in abutting relation with
the upper edge of the sheathing 11' of the lower panel 10'.
As shown in FIGS. 1 and 2, the facing material 14 has the upper
edge thereof aligned and spaced downwardly a selected distance from
the upper edge of the sheathing 11 and the lower edge thereof
aligned and extending beyond the lower edge of the sheathing 11 a
selected distance. The facing material 14 extends beyond one edge
of the sheathing 11 a predetermined distance and approaches an
opposite edge of the sheathing in a preselected space relation.
Stated otherwise, the facing material does not extend to the
opposite edge of the panel. There is a staggering between the
sheathing 11 and the facing material 14. The staggering at the edge
of the panel 10' is complementary to the staggering at the edge of
the panel 10 adjacent thereto to establish an overlapping mating
relation between joined adjacent edges of the panels 10 and 10',
wherein the sheathing 11 of the panel 10 overlaps the sheathing 11'
of the panel 10' and the facing material 14 of the panel 10
overlaps the facing material 14' of the panel 10'. In addition
thereto, a surface of the strip 15 of the panel 10 perpendicular to
the surface 11b of the sheathing 11 abuts against the upper edge of
the sheathing 11' of the lower panel 10'.
By overlapping the sheathing of one panel on the sheathing of the
adjacent panel to be joined therewith and by overlapping the facing
material of one panel on the facing material of the adjacent panel
to be joined therewith, a water seal or weather-proofing joining of
panels for a building exterior is formed. Water blowing into the
building exterior either between the cracks in the facing material
or between the overlapping material will be trapped by the top or
bottom end of the sheathing. The overlap of the sheathing will
enable moisture to be carried away on the sheathing below.
In addition thereto, the strip 15 provides a blowback seal or a
weather resistant barrier for the sheathing on sheathing by
inhibiting the penetration of moisture between confronting surfaces
of the sheathings. The strip 15 abuts against the upper edge of the
sheathing 11' to guide and align the upper panel 10 relative to the
lower panel 10'. Through this arrangement, the lower edge of the
sheathing 11 is elevated from the rafters to rest in the sheathing
11', or the membrane thereon, in an aligned guided manner by the
strip 15 abutting against the upper edge of the sheathing 11'
without a long bridge. This permits the use of rectanguloid facing
material as distinguished from tapered facing material, when
desired, without sacrificing a smooth overlap between joined
adjacent panels.
Thus, the strip 15 serves as a lock strip to positively guide the
upper panel 10 to facilitate the installation of overlapping
panels. Also, the strip 15 aligns the upper panel 10 by raising the
sheathing 11 to a proper angle for the overlapping of the sheathing
11' of the lower panel 10' to permit a smooth overlap whether
rectanguloid or tapered facing material is employed.
