EXTERIOR WALL DECORATIVE FOAM PANEL
BACKGROUND OF THE INVENTION
The present invention relates to the technical field of decoration materials
for
buildings, and more particularly to an exterior wall decorative foam panel
made of foam
and used for attaching onto a surface of an interior wall.
Exterior wall decorative foam originates from the United States, and it is a
new
construction material used to replace conventional construction materials
including
wood and anticorrosive wood. The exterior wall decorative foam has the
advantages
of corrosion resistance, low maintenance, low deformation, waterproof as well
as the
20 As disclosed in U.S. Pat. No. 7,748,183 entitled "System, methods and
compositions for attaching paneling to a building surface," disclosing the
panel has an
upper interlocking member and a lower interlocking member disposed at an upper
end
and a lower end of the panel respectively and a side interlocking member
disposed on
both sides of the panel separately, wherein the upper interlocking members and
the
1
CA 02805312 2013-02-07
lower interlocking members of two opposite panels and the side interlocking
members
on both sides are bevels combined by a tongue-and-groove joint with a contact
angle of
between 22.5 and 77.5 degrees to achieve a tight connection each other. The
panel
further comprises a plurality of weep channels and a plurality of air chambers
formed
on the back surface of the panel to achieve the water drainage and air
circulation effects.
However, the length of the bevel and the tongue-and-groove joint varies with
the
contact angle. The smaller the contact angle, the greater is the length of the
bevel and
the tongue-and-groove joint, and the smaller is the thickness, so that the
decorative
external wall may be cracked or broken easily during transportation. On the
other
hand, the greater the contact angle, the smaller is the length of the bevel
and the
tongue-and-groove joint, so that the interlocking effect may be affected
adversely.
Thus, the most preferred contact angle is 45 degrees.
Since the foam material is
porous and has a waterproof effect that does not absorb water as water is
stored in the
crevices of the panels, therefore the issues of the mildew, fouling and moss
may arise.
Although the panel comes with the design of the weep channels, the foregoing
issues
still exists because the aspect ratio of the panel is a too-large, so that it
is necessary to
increase the thickness of the material or add a reinforcing material to
enhance the
overall strength. The increased thickness results in an increased depth of the
air
chambers and an uneasy drainage. Further, the increased thickness also causes
an
increase of weight and incurs a higher cost. Obviously, the conventional
exterior wall
decorative foam panel requires improvements.
SUMMARY OF THE INVENTION
In view of the aforementioned problems of the prior art, it is a primary
objective
2
CA 02805312 2013-02-07
of the present invention to overcome the problems by providing an exterior
wall
decorative foam panel which comprises a plurality of drainage structures
protruded
from a mounting surface of the exterior wall decorative foam panel and
connected
adjacent to one another, and each drainage structure includes a water
collection part and
a groove in a substantially Y-shape for collecting and guiding water
effectively and
discharging the water from the groove to maintain most areas of the mounting
surface
dry, so as to prevent mildew and moss and extend service life.
Another objective of the present invention is to provide an exterior wall
decorative
foam panel, wherein the drainage structures arranged adjacent to one another
are used,
and the design of a reinforcing mesh is added in the manufacturing process, so
that the
overall strength can be enhanced without increasing the thickness.
A further objective of the present invention is to provide an exterior wall
decorative foam panel comprising a first embedding block, a first embedding
slot, a
second embedding block and a second embedding slot formed at the periphery of
the

Wherein, each bump has an appearance of a rock or a brick to improve the
appearance of the exterior wall decorative foam panel.
Wherein, a total area of the water collection parts equals to 10%-25% of a
total
area of the mounting surface, so that the chance of the mounting surface being
in
contact with water can be reduced. In addition, the drainage structure further
includes
a waterproof coating capable of reducing the chance of absorbing water by the
foam, so

18.
The decorative surface 12 is formed on a first side of the board 11, and the
decorative surface 12 has a plurality of bumps 121 and a plurality of grooves
122
arranged with an interval apart from one another, wherein each of the bump 121
is
manufactured with an appearance of a rock or a brick to give a decorative
effect similar
6
CA 02805312 2013-02-07
to a rock or brick wall to the interior wall 2.
The mounting surface 13 is disposed on a second side of the board 11. In
general,
the board 11 is nailed onto a surface of the interior wall 2, so that the
mounting surface
13 is engaged with a surface of the interior wall 2.
The drainage structures 14 are protruded from the mounting surface 13, so that
after the board 11 is mounted onto the surface of the interior wall 2, the
drainage
structures 14 form sealed spaces respectively, and the drainage structures 14
are
connected adjacent to one another, and each drainage structure 14 includes a
water
collection part 141 and a ditch part 142. The water collection part 141 is
disposed at
an upper section of the mounting surface 13, and both ends of the water
collection part
141 are extended outwardly to form a substantially V-shape, and the water
collection
part 141 has a predetermined angle 0 falling within a range of 30-120 degrees
and
preferably equal to 90 degrees. The ditch part 142 is disposed at an
opening/closing
position of the water collection part 141 to make the drainage structure 14 in
a
substantially Y-shape. A dry area 131 is disposed at a portion of the mounting
surface
13 without the drainage structures 14. It is noteworthy that a waterproof
coating 143 is
coated onto an area of each drainage structure 14 that includes the water
collection part
141 and the ditch part 142 to enhance the waterproof effect, so that water
will not
overflow into the dry area 131. In addition, the water collection parts 141 of
the

edge of
the board 11, and the second embedding slot 17 is a groove inwardly and
concavely
formed on a surface.
The second embedding block 18 is extended and disposed at a second long-side
edge of the board 11, and the installation method is similar to the
installation of the first
embedding block 16 and the first embedding slot 15 and thus will not be
repeated. To
facilitate the installation, the second embedding block 18 has a second bevel
181
disposed on a side opposite to the mounting surface 13, and the second bevel
181 is
gradually tilted from the board 11 towards an edge to provide a guiding
function for the
installation. The second bevel 161 has a second length corresponding to the
depth of
the second embedding slot 17. After the second embedding block 18 is inserted,
the
board 11 gradually pushes a long side of the board 11 until the second
