Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a building wall structure, and more
particularly to a flashing member for use between the confronting
transverse panel ends of upper and lower building panels of the
wall structure.
2. Description of the Prior Art
End joints between upper and lower building panels presenting flat
facing sheets have been formed by tongue and groove connections and
by splice connections -- both joints having exposed caulking. See
U. S. Pat. Nos. 3,357,146 (GARTRELL 1967); 3,530,633 (SCOTT 1970).
End joints between upper and lower building panels presenting
profiled facing sheets have been formed by overlapping a facing
sheet extension of the upper panel with the facing sheet of the
lower panel. See U. S. Pat. No. 3,399,503 (PAYNE et al. 1968).
The exposed caulking of the GARTRELL and SCOTT joints accumulates
dust and dirt and becomes unsightly after a relatively short period
of time. The facing sheet extension profile of PAYNE et al does not
always match the profile of the lower panel facing sheet because of
spreading or gathering the facing sheets of either or both panels
during their manufacture.
SUMMARY OF THE INVENTION
The principal object of this invention is to provide a flashing
member for use at the end joint between upper and lower building
panels, wherein an exposed downwardly extending leg of the flashing
member has a profile corresponding to the profile of the exposed
face of the building panels.
Another object of this invention is to provide a flashing member
adapted for assembly in laterally adjusted, end-to-end overlapped
and interlocked relation with others of the flashing member -- the
lateral adjustment between adjacent flashing members corresponding
with that between adjacent building panels.
The present invention provides a flashing member formed from sheet
material having a generally Z-shaped transverse profile. The
flashing member comprises a horizontal leg, an upwardly extending
rear leg, and a downwardly extending forward leg. The forward edge
of the horizontal leg is contoured whereby the horizontal leg
presents alternating wide sections and narrow sections. The forward
leg extends downwardly from the contoured forward edge and follows
the contour thereof.
One end of the flashing member may be countersunk whereby adjacent
flashing members may be assembled in end-to-end overlapped
relation. The opposite ends of the rear leg may be configured to
provide an overlapped and interlocked connection between the rear
legs of adjacent flashing members.
The rear leg also may be provided with spaced-apart ribs extending
along the length of the rear leg and providing a sealant receiving
channel therebetween.
The present invention also provides a building wall structure of
the type having vertically presented upper and lower building
panels having panel end portions overlapping a horizontal
structural member, such as a girt or a subgirt of a building
structural framework. The upper and lower panels present
confronting transverse panel ends. First and second fastener means
secure the panel end portions of the upper and lower panels to the
horizontal structural member. Each of the building panels comprise
a liner sheet, a profiled exposed face having an other than flat
facing sheet, and an insulating core.
In accordance with the present invention, an integral flashing
member extends the width of the upper and lower panels and has a
horizontal leg positioned between the confronting upper and lower
transverse panel ends with a forward edge thereof presented
outboard of the profiled facing sheet. The forward edge has a
contour corresponding to that of the other than flat exposed face
of the profiled facing sheet. The rear leg extends upwardly between
the panel end portion of the upper panel and the subgirt, and the
forward leg extends downwardly from the forward edge and follows
the contour of the forward edge. The first fastener means secures
the upper panel end portion and the rear leg of the flashing member
to the structural member. In one embodiment, the downward extent of
the forward leg is sufficient to hide the second fastener means
from view. In an alternative embodiment, the second fastener means
secures the forward leg and the panel end portion of the lower
panel to the subgirt.

DESCRIPTION OF THE PREFERRED EMBODIMENT(S)
FIGS. 1 and 2 illustrate a flashing member 10 comprising a
horizontal leg 11, a rear leg 12 and a forward leg 13. The
horizontal leg 11 presents alternating wide and narrow sections 14,
15 respectively between a straight rear edge 16 and a contoured
forward edge 17. The rear leg 12 extends upwardly from the rear
edge 16. The forward leg 13 extends downwardly from the contoured
forward edge 17 and follows the contour thereof. The forward leg 13
presents alternating outboard segments 18 and inboard segments 19
and web segments 20 connecting adjacent ones of the outboard
segments 18 and inboard segments 19.
The flashing member 10 presents a plain end 21 and an opposite
countersunk end 22. The plain end 21 presents transverse end strips
12a, 11a and 13a. The countersunk end 22 presents corresponding
transverse strips 23, 24, 25 of the rear, horizontal and forward
legs 12, 11, 13 which are offset from the exterior surfaces of the
legs 12, 11, 13 by at least one sheet thickness. As will be
described, the countersunk end 22 permits adjacent flashing members
10 to be assembled in laterally adjusted, end-to-end overlapped
relation.
The flashing member 10 may be formed from any suitable material. To
facilitate fabrication, the flashing member may be formed from
plastics by a vacuum forming process. For example, a suitable
plastic material which provides the required weather resistance and
which may be vacuum formed is offered by Eastman Chemical Products,
Inc., a subsidiary of Eastman Kodak Company, under the trademark
UVEX. The UVEX plastic comprises a cellulose acetate butyrate sheet
which may be vacuum formed and is suitable for long term exterior
exposure. The outer surface of the flashing member may have a
molded-in pattern corresponding to the pattern, if any, of the
exposed face of the building panels. Also, the flashing member may
be painted or otherwise finished for color match with the building
panels. Alternatively, the flashing member may be formed from metal
by deep draw metal stamping.
FIG. 3 illustrates a fragment of a wall structure 26 assembled from
an upper course 27 of building panels 28A, 28B and a lower course
29 of building panels 30A through 30C. The building panels 28 and
30 are secured to a building structural framework of which only a
horizontal member 31 is illustrated. A flashing member 10 is
positioned between the confronting transverse ends 32, 33 of the
upper and lower panels 28, 30 respectively. The building panels
28,30 have panel end portions 34, 35 respectively which overlap the
subgirt 31 and are secured thereto as will be described.
Referring liner FIG. 4, each of the building panels 28, 30 comprise
a linear sheet 36, a profiled facing sheet 37 and an insulating
core 38. The profiled facing sheet 37 may present, for example,
alternating crests 39 and valleys 40, and inclined webs 41
connecting adjacent ones of the crests 39 and valleys 40. The
insulating core 38 may comprise any of the well known organic or
inorganic foamed plastics and may be foamed in situ or otherwise
placed between the liner and facing sheets 36, 37. Alternatively,
the core 38 may comprise batts of other insulating materials, such
as glass fiber batts.
The panel end portions 35 of the lower panels 30A, 30B overlap the
subgirt 31 and are secured thereto by fasteners 42. The flashing
members 10A, 10B are installed with the horizontal webs 11 thereof
overlying the transverse ends 33 of the panels 30. It will be
observed in FIG. 4 that the countersunk end 22 of the flashing
member 10A overlaps the plain end 21 of the adjacent flashing
member 10B. The width of the transverse strips 23, 24 and 25 of the
countersunk ends 22 is such that the relative position of the
adjacent flashing members 10A, 10B can be adjusted laterally to
correspond with the laterally adjusted position of the building
panels 30A, 30B.
It will be observed in FIG. 4 that the contoured forward edge 17 of
the horizontal webs 11 is presented outboard of the exposed face of
the building panels 30A, 30B. Also the forward legs 13 of the
adjacent flashing members 10A, 10B are spaced-apart from the
exterior face of the building panels 30 and extend downwardly from
the contoured edge 17 for a distance sufficient to cover the
fasteners 42. Moreover, the forward leg 13 follows the contour of
the facing sheets 37 whereby, when the wall structure 26 is viewed
from a distance, the contoured forward legs 13 are not visually
discernible.
When the upper panel 28A is installed, the transverse lower end 32
thereof confronts the horizontal leg 11 of the flashing member 10A.
Moreover, the panel end portion 34 of the panel 28A overlaps the
rear leg 12 of the flashing member 10A. Fasteners 43 (only one
illustrated) secure the upper panel 28A to the subgirt 31 and also
secure the rear leg 12 of the flashing member 10A to the subgirt
31.
It will be observed in FIG. 4 that the insulating core 38
substantially entirely fills the space between the liner and facing
sheets 36, 37 at the transverse panel ends 32, 33. Where the
insulating core 38 comprises a closed-cell foam plastic, such as
polyurethane, the exposed ends of the core 38 are essentially
impervious to rain and moisture.
Alternative embodiments of the present flashing member will now be
described with reference to FIGS. 5 through 13, wherein
corresponding numerals will be employed to identify corresponding
parts heretofore described.
FIGS. 5 through 7 illustrate a flashing member 50 wherein generally
parallel upper and lower ribs 51, 52 are formed along the length of
the rear leg 12. The ribs 51, 52 are spaced-apart and present a
sealant receiving channel 53 therebetween. The rear leg 12 also is
provided with a first end 54 and an opposite second end 55 which
are configured to provide an end-to-end overlapping, interlocking
connection between adjacent ones of the flashing members 50. It
will best be observed in FIGS. 6 and 7 that the outboard segments
18, the inboard segments 19 and the web segments 20 of the forward
leg 13 are inclined by at least one sheet thickness, inwardly
beneath the contoured forward edge 17 of the horizontal leg 11.
When the flashing member 50 is installed (FIG. 8) the segments 18,
19 and 20 of the forward leg 13 present lower edges 56 approximate
to the profiled facing sheet 37 of the lower panels 30, whereby a
relatively minor shadow will be cast by the lower edges 56. In this
embodiment, the fasteners 45 extend through the inboard segments 19
and are exposed to view. The inboard segments 19 are deflected into
engagement with the facing sheet 37.
It will be observed in FIG. 8 that a sealant 57 is provided in the
lengthwise channel 53 of the rear leg 12. When the upper panel 28
is installed, the liner sheet 36 thereof will engage the sealant
57. When the panel 28 is secured to the member 31 by the fastener
44, the sealant 57 will be compressed between the liner sheet 36
and the rear leg 12 to provide a weathertight seal
therebetween.
Referring to FIG. 9, the first end 54 of the rear leg 12 presents a
pair of upper and lower end segments 58, 59. The upper end segment
is flush with the rear leg 12. The lower end segment is offset from
the rear leg 12 by one sheet thickness. The pair of upper and lower
end segments 58, 59 present a pair of adjacent edges 60, 61 which
extend parallel with the horizontal leg 11. An integral web 62
connects the adjacent edges 60, 61.
The opposite second end 55 presents a pair of upper and lower end
segments 63, 64. The upper end segment 63 is offset from the rear
leg 12 by one sheet thickness. The lower end segment 64 is flush
with the rear leg 12. The upper and lower end segments 63, 64
present a pair of adjacent edges 65, 66 which are spaced-apart and
define a slot 67 open at the end of the rear leg 12.
The overall arrangement is such that the ends 54, 55 of adjacent
flashing members 50A, 50B (FIG. 10) are disposed in end-to-end
overlapping and interlocking relation. It will be observed in FIGS.
10 and 11 that the web 62 of the flashing member 50A is received in
the slot 67 of the adjacent flashing member 50B. The upper end
segment 58 of the first end 54 is confined by the upper end segment
63 of the end 55, whereas the lower end segment 59 and the first
end 54 confines the lower end segment 64 and the second end 55,
thereby to provide an interlocking of the first and second ends 54,
55 of the adjacent flashing members 50A, 50B.
As shown in FIG. 10, the channel 53 (flashing member 50B) may be
provided with a preformed sealant strip 57. Alternatively, the
channel 53 (flashing member 50A) may be provided with a bead 68 of
sealant material. As explained with reference to FIG. 8, the
sealant 57 (68) is compressed between the liner sheet 36 of the
panel 28 and the channel 53, when the panel 28 is installed. In
order to avoid non-uniform compression of the sealant 57 (68), the
outboard surfaces of the upper and lower beads 51, 52 of the upper
end segment 63 and of the lower end segment 59 reside in a common
plane (not illustrated).
FIGS. 12 and 13 illustrate an alternative arrangement of first and
second ends 69, 70 of adjacent flashing members 50C, 50D. In this
arrangement, the first end 69 presents upper and lower end segments
71, 72 wherein the upper end segment 71 is flush with the rear leg
12 and wherein the lower end segment 72 is offset from the rear leg
12 by one sheet thickness. The upper and lower end segments 71, 72
present adjacent edges 73, 74 which are spaced-apart and define a
slot 75 extending parallel with the horizontal leg 11 and which is
open at the end of the rear leg 12.
The opposite second end 70 presents upper and lower end segments
76, 77 wherein the upper end segment 76 is offset from the rear leg
12 by one sheet thickness and wherein the lower end segment 77 is
flush with the rear leg 12. The upper and lower end segments 76, 77
present adjacent edges 78, 79. An integral web 80 connects the
adjacent edges 78, 79.
The overall arrangement is such that, as shown in FIG. 13, the web
80 of the flashing member 50D is received in the slot 75 of the
flashing member 50C, thereby to provide an interlocking of the ends
69, 70.
