Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The invention relates to trim members used in connection
with the application of stucco and other wall coating materials to
the exteriors of buildings and building foundations and, more
particularly, to screed joints which facilitate the application of
different thicknesses of stucco, plaster or similar materials to
building walls.
[0003] 2. Description of the Invention Background
[0004] Plaster, cement and stucco-type building materials have been
employed in the construction of walls for residential and
commercial buildings for many years to achieve a variety of
different designs and wall textures. Various methods and
application techniques exist for applying such materials to walls
and other structures. One such method that is commonly employed
involves attaching lath material to a wall frame constructed from
wood or metal studs. The lath material serves to stabilize the
plaster while it is in its flowable state prior to drying. Similar
approaches are also commonly employed when the underlying structure
is fabricated from, for example, concrete or concrete blocks. The
lath material is applied to the wall surface (exterior or
interior--what ever the case may be) and then the plaster material
is applied to the lath. In other applications, however, the plaster
is applied directly to sheathing or wallboard material.
[0005] In the past, trim members known as "weep screeds" have been
developed to for use in connection with the application of stucco,
plaster or similar materials to exterior framed walls. Such trim
members are commonly attached to the base of an exterior framed
wall and are strategically positioned to overlap the joint between
the exterior framed wall and the foundation wall. The weep screeds
serve to provide support for the stucco or plaster coating that is
applied to the exterior framed wall and also facilitate drainage
for water between the exterior framed wall and the underlying
foundation. These trim members commonly have a vertical attachment
member and an outwardly protruding flange that angles downwardly
from the bottom of the vertical attachment member. The outwardly
protruding flange bends downwardly and rearwardly toward the
foundation. A vertically extending lip is commonly formed on the
end of the flange.
[0006] Water that contacts the exterior coating surface may be
absorbed into the surface and into the building layers beneath the
exterior coating surface. When weep screeds are employed, the water
drains down and weeps from the structure along the edges of the
weep screed. Weep screed are generally intended to reduce moisture
penetration into the wall cavity, particularly in areas where water
is permitted to accumulate where the upper and lower walls join
together. Prior weep screed arrangements are ill-suited for
applications wherein a second thickness of the stucco or plaster
material is to be applied to the foundation itself.
[0007] In addition, in applications involving walls of different
construction, which is often the case in applications wherein the
walls are of framed construction and the foundation walls are
formed of concrete materials, those walls may expand and contract
at different rates. Prior weep screed arrangements are ill-suited
for accommodating such movement between the walls, particularly in
applications wherein the stucco or plaster materials are applied to
the framed walls and the foundation walls.
[0008] Thus, there is a need for screed joints that form screed
edges to accommodate adjoining stucco or plaster materials that are
of different thicknesses and that are applied to joint between
exterior framed walls and foundation walls. There is a further need
for screed joints that are flexible and capable of accommodating
movement due to, for example, expansion and contraction of the of
the adjoining wall structures which may be of dissimilar
construction.
SUMMARY
[0009] In accordance with one embodiment of the present invention,
there is provided a screed joint that comprises a first attachment
flange and a first screed wall that extends from the first
attachment flange at a first obtuse angle. The first screed wall
has a distal end that is spaced from the first attachment flange. A
second screed wall extends from the distal end of the first screed
wall and also has a proximal end. A second support flange extends
from the proximal end of the second screed wall and forms a second
angle therewith. A screed lip extends from the second screed wall
at a location between the distal end of the first screed wall and
the proximal end of the second screed wall.
[0010] Another embodiment of the present invention comprises a
screed joint that has a first attachment flange and a second base
flange that is spaced from the first attachment flange. A first
screed wall extends from the first attachment flange at a first
obtuse angle and has a distal end that is spaced from the first
attachment flange. A second screed wall extends from the second
base wall and has a proximal end and a distal end. A flexible
attachment assembly extends between the distal end of the first
screed wall and the distal end of the second screed wall such that
the first and second screed walls are in spaced relationship to
each other to facilitate flexible movement therebetween. A screed
lip extends from the second screed wall at a location between the
distal end of the second screed wall and the proximal end of the
second screed wall.
[0011] Another embodiment of the present invention comprises a
screed joint for use in connection with a first lower wall and a
second upper wall that is supported on the first lower wall and
which forms a joint therebetween. One embodiment of the screed
joint comprises a lower screed portion that is attachable to the
first lower wall adjacent the joint and an upper screed portion
that is attachable to the second upper wall to slidably overlap a
portion of the lower screed portion. The upper screed portion
defines a space between the upper screed portion and the lower
screed portion for receiving a sealant material therein.
[0012] Another embodiment of the present invention comprises a wall
structure that includes a first wall that has a first wall surface
and a second wall that is supported on the first wall such that a
joint is formed therebetween. The wall structure further includes a
screed joint that comprises a first attachment flange that is
attached to the second wall. A first screed wall extends from the
first attachment flange at a first obtuse angle and has a distal
end that is spaced from the first attachment flange. A second
screed wall extends from the distal end of the first screed wall.
The second screed wall forms a second angle therewith. A screed lip
extends from the second screed wall at a location between the
distal end of the first screed wall and the proximal end of the
second screed wall. A first amount of plaster is applied to the
first wall surface such that the thickness of the first amount of
plaster is equivalent to a distance between the screed lip and the
first wall surface. A second amount of plaster is applied to the
second wall surface and has a thickness that is equal to another
distance between the distal end of the first screed wall and the
first wall surface.

DETAILED DESCRIPTION OF THE INVENTION
[0023] Referring now to the drawings for the purposes of
illustrating the present embodiments of the invention only and not
for the purposes of limiting the same, FIGS. 1-3 illustrate one
embodiment of a screed joint 100 of the present invention used in
connection with the application of plaster, stucco, etc. to the
wall surfaces of a building. As used herein, the term "plaster"
encompasses not only commercially available wall plaster materials,
cement and stucco materials, but also essentially any materials
that are flowable in an uncured state and which solidify in a cured
state. Also, the terms "first story" and "second story" and "first
wall" and "second wall" have been used herein in an exemplary
manner to described one use of various embodiments of the subject
invention. Such terms should in no way be deemed as limiting use of
various embodiments to use solely between first and second story
walls. Various embodiments of the present invention could be
effectively used between a varieties of adjoining walls regardless
of which stories the adjacent walls are located on.
[0024] FIGS. 1-3 illustrate one screed joint 100 that may be used
in connection with a building 10 that has a foundation 20 and a
first story 30 that is supported on and attached to the foundation
20. In one application, the foundation 20 is fabricated from
concrete materials. For example, the foundation 20 may be
fabricated from concrete blocks, poured concrete, etc. The
foundation 20 has a first wall 22 that has a first wall surface 24.
See FIG. 3.
[0025] The first story 30 that is located on the foundation 20 may,
for example, be of framed construction and be fabricated from wood
or metal framing components generally designated as 32. Wallboard
material 34 such as that material sold under the trademark
CELOTEX.RTM. or other sheet materials such as plywood, particle
board, etc. may be attached thereto to form a second wall 36 that
has a second wall surface 38. In this embodiment, the second wall
surface 38 is substantially coplanar with the first wall surface
24. For example, the wall surfaces 24, 38 are located on a plane
A-A as shown in FIG. 3. A space or joint 40 is formed between the
first wall 22 of the foundation 20 and the second wall 36 of the
first story. The screed joint 100 of the present invention is sized
to span the joint 40 as shown in FIG. 3.
[0026] As can be seen in FIGS. 1 and 2, one embodiment of the
screed joint 100 includes a first attachment flange 110 that may be
provided with a series fastener holes 112 for receiving fasteners
114 to attach the first attachment flange 110 to the second wall
36. Fasteners 114 may comprise, for example, nails, screws, etc. In
one embodiment, for example, the fastener holes are spaced
approximately six inches on center. However, other fastener spacing
and fastener arrangements may be used. The first attachment flange
110 has a height "H". In one embodiment, for example, "H' may be
approximately 31/2 inches. However, the attachment flange 110 may
be provided with other heights, if desired. In addition, the first
attachment flange 110 may be perforated to enable the plaster
material to flow into the perforations.
[0027] A first angled screed wall 130 protrudes from the first
attachment flange 110 such that a first angle "B" is formed
therebetween. In one embodiment, the first angle "B" is greater
than 90.degree.. The portion of the first angled screed wall 130
that is spaced from the first attachment flange 110 is referred to
herein as a distal end 132. When the first attachment flange 110 is
attached to the second wall 36, the distal end 132 is spaced from
the second wall surface 38 of the second wall 36 a distance "C"
that is substantially equal to the desired thickness of a second
amount of plaster or stucco 190 to be applied to the second
exterior surface 38 of the second wall 36. Thus, the distal end 132
of the first angled screed wall 130 may function as a reference
screed for applying a desired second amount of stucco or plaster
190 to the second wall 36. The installer may find it convenient to
place a portion of a screed tool or other type of leveling tool on
the distal end 132 of the first angled screed wall 130 to screed
off the excess plaster so that the second amount of plaster 190 has
a substantially uniform thickness. In one embodiment, for example,
distance "C" is approximately 3/4 inch. In another embodiment,
distance or thickness "C" is approximately 7/8 inch. However,
distance "C" may vary depending upon the application.
[0028] A second screed wall 140 extends from the distal end 132 of
the first angled screed wall 130 and has a proximal end 142 that
has a second support flange 150 extending therefrom. The second
support flange 150 is substantially coplanar with the first
attachment flange 110 and forms a second angle "D" with respect to
the second screed wall 140. In one embodiment, angle "D" is
approximately 90.degree.. However, angle "D'" may comprise other
angles without departing from the spirit and scope of the present
invention. In one embodiment, the second support flange 150 may
have a length "L" that is approximately 11/2 inches. However, the
second support flange 150 may be provided with different lengths
"L", depending upon the application. See FIG. 2. In one embodiment,
the second support flange 150 is not attached to the first wall 22
as shown in FIG. 3.
[0029] A screed lip 160 extends downwardly from the second screed
wall 140 as shown in FIGS. 1-3. The outermost edge of the screed
lip 160 is located a distance "E" from the first exterior surface
24 of the first wall 22 when the screed joint 100 is attached to
the second wall 36 as shown in FIG. 3. The screed lip 160 may
function as a reference screed for applying a desired first amount
of stucco or plaster 180 to the first wall 22. The installer may
find it convenient to place a portion of a screed tool or other
type of leveling tool on the screed lip 160 to screed off the
excess plaster so that the first amount of plaster 180 has a
substantially uniform thickness. Thus, distance "E'" may be
substantially equal to the desired thickness of the first amount of
plaster or stucco 180 to be applied to the exterior surface 24 of
the wall 22. In one embodiment, for example, distance "E" may be
approximately 1/2 inch. In another embodiment, distance "E" may be
3/8 inch. However, distance "E" may vary depending upon the
application. Also in one embodiment, the screed lip 160 may
protrude outwardly from the second screed wall 140 approximately
1/4 inch. However, the screed lip 160 may be provided with other
lengths.
[0030] To facilitate drainage of moisture/water that might
infiltrate between the upper amount of plaster 190 and the second
exterior surface 38 of the second wall 36 and migrate into the
joint 40 between the first wall 22 of the foundation 20 and the
second wall 36 of the first story, one or more weep holes 170 may
be provided through the second screed wall 140. The weep holes 170
provide avenues for the water drain from the screed joint 100. In
other embodiments, one or more weep holes 170 may also be provided
through the first angled screed wall 130 and, in other embodiments,
no weep holes may be provided through either of the screed walls
130, 140.
[0031] In one embodiment, a space "S" is provided between the first
angled screed wall 130 and the second angled screed wall 140 at the
distal end 132. See FIG. 2A. In one embodiment, "S" is
approximately 1/4 inch. Such space facilitates the movement of the
screed walls 130, 140 relative to each other to enable them to
accommodate slight movements of the first and second amounts of
plaster 180, 190.
[0032] FIG. 4 illustrates another screed joint 200 of the present
invention used in connection with a building 10 that has a
foundation 20 and a first story 30 that is supported on and
attached to the foundation 20. As described above, the foundation
20 may be fabricated from concrete or other materials. The
foundation 20 has a first wall 22 that has a first wall surface 24.
The first story 30 that is located on and attached to the first
wall 22 may, for example, be constructed from wood or metal framing
components 32. Wallboard material 34 such as that material sold
under the trademark CELOTEX.RTM. or plywood may be attached thereto
to form a second wall 36 that has a second wall surface 38. In this
embodiment, the second wall surface 38 is not substantially
coplanar with the first wall surface 24. Thus, in this embodiment,
the wall surface 24 lies along a plane H-H and the wall surface 38
lines along a plane G-G. Planes G-G and H-H are not coplanar with
each other. In one embodiment, planes G-G and H-H may be
approximately 7/16 inches apart which may be equivalent to the
thickness of the wallboard comprising the second wall 36. A space
or joint 40 is formed between the first wall 22 of the foundation
20 and the second wall 36 of the first story. The screed joint 200
of the present invention is sized to span the joint 40 as shown in
FIG. 4.
[0033] this embodiment, the screed joint 200 is substantially
identical to screed joint 100 except that the second screed wall
240 of joint 200 is wider than the second screed wall 140 to
accommodate the offset nature of the first wall 22 and the second
wall 36. The screed joint 200 has a first attachment flange 210
that may be provided with a series fastener holes for receiving
fasteners 214 to attach the first attachment flange 210 to the
second wall 36. Fasteners 214 may comprise, for example, nails,
screws, etc.
[0034] A first angled screed wall 230 protrudes from the first
attachment flange 210 such that a first angle "B'" is formed
therebetween. In one embodiment, the first angle "B'" is greater
than 90.degree.. However, angle "B'" could comprise other angles.
The portion of the first angled screed wall 230 remote from the
first attachment flange 210 is referred to herein as a distal end
232. When the first attachment flange 210 is attached to the second
wall 36, the distal end 232 is spaced from the second wall surface
38 of the second wall 36 a distance "C'" that is substantially
equal to the desired thickness of a second amount of plaster or
stucco 190 to be applied to the second exterior surface 38 of the
second wall 36. Thus, the distal end 232 of the first angled screed
wall 230 may function as a reference screed for applying a desired
second amount of stucco or plaster 190 to the second wall 36. The
installer may find it convenient to place a portion of a screed
tool or other type of leveling tool on the distal end 232 to screed
off the excess plaster so that the second amount of plaster 190 has
a substantially uniform thickness. In one embodiment, for example,
distance "C'" is approximately 3/4 inch. In another embodiment,
distance "C'" is approximately 7/8 inch. However, distance "C" may
vary depending upon the application.
[0035] A second screed wall 240 protrudes from the distal end 232
of the first angled screed wall 230 and has a proximal end 242 that
adjoins a second support flange 250. The second support flange 250
is not coplanar with the first attachment flange 210 and forms an
angle "D'" with respect to the second screed wall 240. In one
embodiment, angle "D'" is approximately 90.degree.. However, angle
"D'" may comprise other angles. In one embodiment, the second
support flange 250 is not attached to the first wall 22 as shown in
FIG. 4.
[0036] A screed lip 260 protrudes downward from the second screed
wall 240 and is located such that the outermost edge of the screed
lip 260 is a distance "E'" from the first exterior surface 24 of
the first wall 22 when the screed joint 200 is attached to the
first wall 36 as shown in FIG. 4. The screed lip 260 may function
as a reference screed for applying a desired first amount of stucco
or plaster 180 to the first wall 22. The installer may find it
convenient to place a portion of a screed tool or other type of
leveling tool on the screed lip 260 to screed off the excess
plaster so that the first amount of plaster has a substantially
uniform thickness. Thus, distance "E'" may be substantially equal
to the desired thickness of the first amount of plaster or stucco
180 to be applied to the exterior surface 24 of the wall 22. In one
embodiment, for example, distance "E'" may be approximately 1/2
inch. In another embodiment, distance "E'" may be 3/8 inch.
However, distance "E'" may vary depending upon the application.
Also in one embodiment, the screed lip 260 may protrude outwardly
from the second screed wall 240 approximately 1/4 inch. However,
the screed lip 260 may be provided with other lengths.
[0037] When installed as shown in FIG. 4, a flowable elastic
sealant material 192, such as a commercially available silicone
sealant material, is placed between the inside surface of the
second screed wall 240 and the bottom of the wallboard 34 to create
a substantially weatherproof seal therebetween. To facilitate
drainage of moisture/water that might infiltrate between the first
amount of plaster 190 and the second exterior surface 38 of the
second wall 36 and to prevent it from accumulating within the
screed joint 200, one or more weep holes 270 may be provided
through the second screed wall 240. The weep holes 270 provide
avenues for the water drain from the screed joint 200. In other
embodiments, no weep holes are provided.
[0038] FIGS. 5 and 6 illustrate a flexible screed joint 300 of the
present invention that may be used in connection with a building 10
that has a foundation 20 and a first story 30 that is supported on
and attached to the foundation 20. As described above, the
foundation 20 may be fabricated from concrete or other materials.
The foundation 20 has a first wall 22 that has a first wall surface
24. See FIG. 6.
[0039] The first story 30 that is located on and attached to the
first wall 22 may, for example, be constructed from wood or metal
framing components 32. Wallboard material 34 such as that material
sold under the trademark CELOTEX.RTM. or plywood may be attached
thereto to form a second wall 36 that has a second wall surface 38.
A space or joint 40 is formed between the first wall 22 of the
foundation 20 and the second wall 36 of the first story 30. The
screed joint 300 of the present invention is sized to span the
joint 40 as shown in FIG. 6.
[0040] This embodiment of the present invention includes a first
attachment flange 310 that may be provided with a series fastener
holes for receiving fasteners 314 to attach the first attachment
flange 310 to the wall 36. Fasteners 314 may comprise, for example,
nails, screws, etc. Attachment flange 310 has a height "H". IN one
embodiment "H" is approximately 31/2 inches. However, height "H":
may vary depending upon the application.
[0041] This embodiment also includes a second base flange 350 that,
in one embodiment, is spaced from and substantially coplanar with
the first attachment flange 310. The second base flange 350 may be
provided with holes for receiving fasteners to attach the second
base flange 300 to the first wall 22 or the second base flange 350
may not be attached to the first wall 22. The second base flange
350 has a height designated as "K". In one embodiment "K" is
approximately 11/2 inches. However, "K" may vary depending upon the
application.
[0042] A first screed wall 330 extends from the first attachment
flange 310 and a second screed wall 340 extends from the second
base flange 350. A flexible attachment assembly, generally
designated as 339, extends between the first screed wall 330 and
the second screed wall 340 to facilitate movement between the first
screed wall 330 and the second screed wall 340. The portion of the
first screed wall 330 that adjoins the first attachment flange 310
is referred to herein as the first proximal end 332. The portion of
the first screed wall 330 that is remote from the first attachment
flange 310 is referred to herein as the first distal end 334. The
first distal end 334 may be located a distance "C''" from the first
attachment flange 310 wherein distance "C''" corresponds to a
desired thickness of second plaster material 190 to be applied to
the second exterior surface 38 of the second story wall 36 as will
be discussed in further detail below. Thus, the first distal end
334 of the first screed wall 430 may function as a reference screed
for applying a desired second amount of stucco or plaster 190 to
the second wall 36. The installer may find it convenient to place a
portion of a screed tool or other type of leveling tool on the
first distal end 334 to screed off the excess plaster so that the
second amount of plaster 190 has a substantially uniform thickness.
In one embodiment, for example, distance "C''" may be approximately
3/4 inch. In other embodiments, "C''" is approximately 7/8 inch.
However, "C''" could vary depending upon the application.
[0043] The portion of the second screed wall 340 that adjoins the
second base flange 350 is referred to herein as the second proximal
end 342. The second screed wall 340 further has a second distal end
or drip edge 344 and an intermediate screed lip 360 protruding
therefrom. Screed lip 360 is located a distance "E''" from the
first exterior surface 24 of the first wall 22 when the screed
joint 300 is attached to the second wall
[0044] FIG. 5. The screed lip 360 may function as a reference
member for applying a desired second amount of stucco or plaster
190 to the first wall 22. Thus, distance "E''" is substantially
equal to the desired thickness of the second amount of plaster or
stucco 190 to be applied to the first exterior surface 24 of the
first wall 22. In one embodiment, for example, distance "E''" may
be approximately 1/2 inch. In another embodiment, distance "E''"
may be 3/8 inch. However, distance "E''" may vary depending upon
the application.
[0045] In one embodiment, the flexible attachment assembly 339 may
have an accordion-like shape and include a first intermediate web
370 and a second intermediate web 380. The first intermediate web
370 adjoins the first screed wall 330 at its first distal end 334
and extends inwardly to form a first proximal end 372 that is
spaced from the first proximal end 332 of the first screed wall 130
a distance "I" and from the second proximal end 342 of the second
screed wall 340 a distance "J". In one embodiment, for example,
distance I could be approximately 1/4 inch and distance "J" could
be approximately 1/4 inch. Other distances could also be employed
which are sufficient to enable the first and second screed walls
330, 340 to move relative to each other. As can be seen in FIG. 5,
the second intermediate web 380 extends from the proximal end 372
of etch first intermediate web 370 to the second distal end 344 of
the second screed wall 340 to complete the flexible attachment
assembly 339. See FIG. 5.
[0046] To facilitate drainage of moisture/water that might
infiltrate between the upper amount of plaster 190 and the second
exterior surface 38 of the second wall 36 and to prevent it from
accumulating within the screed joint 300, one or more weep holes
390 may be provided through the first intermediate web 370. See
FIG. 5. The weep holes 390 provide avenues for the water drain from
the screed joint 300. In additional embodiments, weep holes may
also be provided through the second intermediate web 380 and the
second screed wall 340. In other embodiments, no weep holes are
provided through any of portion of etch screed joint 300.
[0047] The screed joint 300 may be used as follows. After the first
wall 22 and the second wall 36 have been constructed such that a
space or joint 40 is formed therebetween, the screed joint 300 is
oriented such that it spans the joint 40 and the first attachment
flange 310 is in confronting relationship with the second exterior
surface 38 of the second wall 36. Suitable fasteners 314 are
inserted through at least some of the fastener holes in the first
attachment portion 310 to attach the first attachment flange 310 to
the second wall 36.
[0048] The second base flange 350 is also oriented in confronting
relationship with the first exterior surface 24 of the first wall
22. Suitable fasteners may be used to attach the second base flange
350 to the first wall 22 or the second base flange 350 may not be
attached to the first wall 22. See FIG. 6.
[0049] After the screed joint 300 has been attached in the
above-described manner, the first amount of plaster, stucco, etc.
180 is applied to the first exterior surface 24 of the first wall
22 so that the outer surface 181 of the first plaster 180 stops at
or is substantially even with the screed lip 360 as shown in FIG.
6. The installer may find it convenient to place a portion of a
screed tool or other type of leveling tool on the screed lip 360 to
screed off the excess plaster so that the first amount of plaster
has a substantially uniform thickness. Thus, the thickness of the
first amount of plaster 180 is substantially equivalent to distance
"E''" in this embodiment. Likewise, a second amount of plaster 190
is applied to the second wall surface 38 of the second wall 36 so
that the outer surface 191 of the second amount of plaster 190
stops at or is substantially even with the distal end 334 of the
first angled screed wall 330. Again, the installer may find it
convenient to place a portion of the screed tool or other leveling
tool on the distal end 334 to screed off or remove the excess
plaster 190 so that the second amount of plaster has a
substantially uniform thickness. Thus, the thickness of the second
amount of plaster 190 is substantially equivalent to distance "C''"
in this embodiment. The second amount of plaster 190 covers the
first attachment flange 310 and the heads of fasteners 314.
[0050] FIGS. 7 and 8 illustrate a two-piece screed joint 400 of the
present invention that may be used in connection with a building 10
that has a foundation 20 and a first story 30 that is supported on
and attached to the foundation 20. As described above, the
foundation 20 may be fabricated from concrete or other materials.
The foundation 20 has a first lower wall 22 that has a first wall
surface 24. The first story 30 that is located on and attached to
the first wall 22 may, for example, be constructed from wood or
metal framing components 32. Wallboard material 34 such as that
material sold under the trademark CELOTEX.RTM. or plywood may be
attached thereto to form a second wall 36 that has a second wall
surface 38. A space or joint 40 is formed between the first lower
wall 22 of the foundation 20 and the second upper wall 36 of the
first story 30. The two piece screed joint 400 of the present
invention is sized to span the joint 40 as shown in FIG. 8.
[0051] This embodiment of the present invention includes an upper
screed portion 402 and a lower screed portion 500. The upper screed
portion 402 includes a first attachment flange 410 that may be
provided with a series fastener holes 412 for receiving fasteners
414 to attach the first attachment flange 410 to the second upper
wall 36. Fasteners 414 may comprise, for example, nails, screws,
etc.
[0052] A first angled screed wall 430 protrudes from the first
attachment flange 410 such that a first angle "M" is formed
therebetween. In one embodiment, the first angle "M" is preferably
greater than 90.degree.. The first angled screed wall 430 has a
distal end 432. When the first attachment flange 410 is attached to
the second wall 36, the distal end 432 is spaced from the second
wall surface 38 of the second wall 36 a distance "N" that is
substantially equal to the desired thickness of a second amount of
plaster or stucco 190 to be applied to the second exterior surface
38 of the second wall 36. In one embodiment, for example, distance
"N" is approximately 3/4 inch. In another embodiment, distance "N'"
is approximately 7/8 inch. However, distance "N" may vary depending
upon the application.
[0053] A second screed wall 440 protrudes from the distal end 432
of the first angled screed wall 430 and has a proximal end 442 that
has a second support flange 450 protruding therefrom. The second
support flange 450 is substantially coplanar with the first
attachment flange 410 and forms a second angle "O" with respect to
the second screed wall 440. In one embodiment, angle "O" is
approximately 90.degree..
[0054] The second screed portion 500 of this screed joint 400
includes a second or lower attachment flange 510 that is adapted
for attachment to the first surface 22 of the first lower wall 24
by a series of fasteners 514 that extend through fastener holes
512. In one embodiment, the fasteners 514 comprise commercially
available concrete fasteners. However, other suitable fasteners may
be employed.
[0055] A lower screed wall 530 protrudes outward from the second
attachment flange 510. The lower screed wall 530 may be arranged to
form an angle "P" with the second attachment flange 510. In one
embodiment, angle "P" is 90.degree.. However, angle "P" could
comprise other angles. The lower screed wall 530 terminates in a
distal end 532. In one embodiment, a screed lip 560 is formed on
the distal end 532. Screed lip 560 is located a distance "Q" from
the first exterior surface 24 of the first wall 22 when the second
portion 500 of the screed joint 400 is attached to the second first
wall 22 as shown in FIG. 8. In one embodiment, for example,
distance "Q" may be approximately 1/2 inch. The screed lip 560 may
function as a reference member for applying a desired first amount
of stucco or plaster 190 to the first wall 22. Thus, distance "Q"
is substantially equal to the desired thickness of the first amount
of plaster or stucco 190 to be applied to the first exterior
surface 24 of the first wall 22.
[0056] As can be seen in FIG. 8, the second attachment flange 510
is attached to the first wall 22. The upper screed portion 402 is
then oriented adjacent the second wall surface of the second wall
36 such that the first angled screed wall 430 overlaps an upper
portion 512 of the second attachment flange and the second base
flange 450 is in slidable contact with the upper portion 512 of the
second attachment flange 510. As can be seen in FIG. 8, such
arrangement defines a space 570 between the second screed wall 440
and the lower screed wall 530. In one embodiment, a flexible
weatherproof seal 580 is formed between the second screed wall 440
and the lower screed wall 530 to prevent infiltration of
moisture/water between the upper screed portion 402 and lower
screed portion 500. In one embodiment, a conventional insulation
backer rod 582 is installed in space 550 and is retained therein by
a flowable elastic sealant material 584 which may comprise
conventional silicone sealant or conventional sealants.
[0057] After the screed joint 400 has been attached in the
above-described manner, the first amount of plaster, stucco, etc.
180 is applied to the first wall surface 24 of the first wall 22 so
that the outer surface 181 of the first plaster 180 stops at or is
substantially even with the screed lip 560 as shown in FIG. 8. The
installer may find it convenient to place a portion of a screed
tool or other type of leveling tool on the screed lip 560 to screed
off the excess plaster 180 so that the first amount of plaster 180
has a substantially uniform thickness. Thus, the thickness of the
first amount of plaster 180 is substantially equivalent to distance
"Q" in this embodiment. Likewise, a second amount of plaster 190 is
applied to the second wall surface 38 of the second wall 36 so that
the outer surface 191 of the second amount of plaster 190 stops at
or is substantially even with the distal end 432 of the first
angled screed wall 430 as shown in FIG. 8. Again, the installer may
find it convenient to place a portion of the screed tool or other
leveling tool on the distal end 432 to screed off or remove the
excess plaster 190 so that the second amount of plaster 190 has a
substantially uniform thickness. Thus, the thickness of the second
amount of plaster 190 is substantially equivalent to distance "N"
in this embodiment. The second amount of plaster 190 covers the
first attachment flange 410 and the heads of fasteners 414. The
reader will appreciate that such two part screed joint 400 enables
the second wall 36 and the second amount of plaster 190 applied
thereto to move relative to the first wall 22 and the first amount
of plaster 180 applied thereto.
[0058] To facilitate drainage of moisture/water that might
infiltrate between the upper amount of plaster 190 and the second
exterior surface 38 of the second wall 36 and to prevent it from
accumulating within the screed joint 300, one or more weep holes
590 may be provided through the first angled screed wall 430. See
FIG. 8. The weep holes 590 provide avenues for the water drain from
the screed joint 400. In additional embodiments, weep holes 590 may
also be provided through the second screed wall 440. In other
embodiments, no weep holes are provided through any of portion of
etch screed joint 400.
[0059] The various screed joint embodiments of the present
invention may be fabricated from vinyl material utilizing
conventional extrusion techniques and equipment. For example,
Exterior Grade polyvinylchloride (PVC) having the following grade
numbers is particularly well-suited for exterior applications:
ASTM-D-4216, ASTM-C-1063, and ASTM-D-1784. However, the various
screed joint embodiments of the present invention could also be
fabricated from other polymer materials having the desired
ultraviolet light resistance, etc. or metal materials or the like
could be employed without departing from the spirit and scope of
the present invention.
[0060] As can be appreciated from the foregoing description, the
unique and novel screed joint embodiments of the present invention
solve many problems encountered when applying different thicknesses
of plaster along adjoining building walls. Various embodiments of
the present invention provide an effective way of establishing the
desired thickness of materials to be applied while forming screed
walls along a point wherein the different thicknesses of material
are adjacent to each other. Various embodiments of the subject
invention also enable the first screed wall to move independent
from the second screed wall to accommodate different material
movements due to, for example, differences in thermal expansion and
contraction. While various embodiments of the screed joint of the
present invention are particularly well suited for use in
connection with adjoining walls of dissimilar construction, various
embodiments of the present invention can also be effectively used
along joints between walls of like construction. Thus, the scope of
protection afforded to various embodiments of the present invention
should not solely be limited to applications involving use with
walls, structures, etc. that are of dissimilar construction.
[0061] The invention which is intended to be protected is not to be
construed as limited to the particular embodiments disclosed. The
embodiments are therefore to be regarded as illustrative rather
than restrictive. Variations and changes may be made by others
without departing from the spirit of the present invention.
Accordingly, it is expressly intended that all such equivalents,
variations and changes which fall within the spirit and scope of
the present invention as defined in the claims be embraced
thereby.
