INSULATING PANEL FOR THE OUTER INSULATION AND OUTER DRAINAGE OF SUBTERRANEAN WALLS

Abrégé anglais

ABSTRACT OF THE DISCLOSURE
The insulating panel comprises a plurality of
vertically extending drainage channels (1). A connecting
channel (4) extends along the upper (2) and lower (3)
edge of the panel and communicates with all drainage
channels (1). This allows, that vertically adjacent
panels may be laterally offset to each other to such an
extent, that no vertical communication between vertically
adjacent drainage channels (1) exists. The draining is
nevertheless secured in that the water flowing down the
upper drainage channels (1) will accumulate and flow
laterally along the connecting channel (4) and proceed
from there further through the drainage channels (1) of
the lower panel.

Description

INSULATING PANEL FOR THE OUTER INSULATION
AND OUTER DRAI~AGE OF SUBTERRANEAN WALLS
The invention relates -to an insulating panel
for thermal in~ulation and for water drainage of sub
terranean, ba~ement, building or cons-truction walls.
The panel has a plurality of drainage channels which
are open on one surface of the panel and which extend
from a fi.rst panel edge to a second panel edge located
oppositely thereto and are open at both panel edges.
Such insulating panels are used for thermal
insulation on the outer side o~ the wall and for water
drainage of such walls. During construction the panels
are placed against the wall to be protected prior to
the backfilling of earth. Apart from their temperature
insulating properties these panels provide for the
drainaye of water, specifically rain water which can
flow along the drainage channels downwardly into the
ground or into water collection pipes.
Such panels, each have a plurality of vertically
extending grooves, such as disclosed, e.g., in ~erman
published patent application No. DE-31 13 807. The
panels have a common drawback, however, in that the
31,908-F 1-

--2--
vertically extending drainage grooves of the individual
panels which are located vertically on top of each
other may not be properly aligned during the build-up
of such outer cladding of a wall. Alternatively, the
vertically stacked panels may shift laterally relative
to each other or may get partly clogged such that
various blockages of the draining channels wlll occur.
An object of the inven-tion is to provide an
insulating panel of the kind metioned above, which does
not feature the aforementioned drawbacks and which
provides for effective drainage at all lateral relative
positions of the individual panels forming the outer
covering for subterranean walls.
According to the invention, the insulating
panel is characterized in that a connecting channel
each is located in the side surfaces of the panel
extending along the first and in the second panel edg~
and communicating with every drainage channel and
extending perpendicularly thereto.
Pref~rably, the insulating panel is an integral
structural member and has the shape of two plate bodies
located on top of each other and offset in diagonal
direction relative to each other, such that every side
surface of the panel ahs a step-like extent whereby
adjacent panels overlap partly and guide each other.
The panel surface which is provided with the drainage
channels can be covered by a web-like material such
that the drainage channels are covered and protected
from clogging-up by soil, gravel or ~he like entering
the channels.

The subject of the invention will be described
in greater detail below upon reference to the annexed
d.rawings, wherein:
Figure 1 is a perspective view of an upper
s~ction of an insulating panel,
Figure 2 is a perspective view of adjacent
end sections of two vertically positioned panels,
Figure 3 is a section through two vertically
adjacent panels illustra-ting one embodiment of a connecting
channel,
Figure 4 is a section through an upper end
part of an insulating panel showing a further embodiment
of the cross-section shape of the connecting channel,
Figure 5 is a view similar to the view of
1~ Figure 4 of a further e~bodiment of the connecting
channel,
Figure 6 is a side view o an insulating
panel provided with a drainage channel covering web,
and
Figure 7 is a top view of the panel illustrated
in Figure 6.
The insulation panel of which an upper end
portion is shown in Figure 1 can be fabricated of any
kind of suitable material, such as an extruded plastics
material, a foamed plastics material or a mortar-bound
material. In the preferred embodiment, the insulating
31,908-F -3

plate is made of an e~truded polystyrene foam. One
main surface of the panel is provided with ~ertically
extending parallel drainage channels 1, which ex-tend
along the entire vertical length of the panel. A
connecting channel 4 is formed in the top side surface
2 of the panel. A similar connecting channel 4 is
provided at the bottom side surface 3, such as is
shown, for exampl~, in Figures 2 and 3. The connecting
channel 4 extends in a direction perpendicular to the
drainage channels 1 and is offset relative to the
drainage cha~nels 1 in the direction of the panel
thickness. As can be seen from Figures 1, 2 and 3, the
drainage channels 1 partly intersect the connecting
channel 4 such that the outer side wall of the connecting
channel 4 has a plurality of openings 5, each of which
forms a passageway communicating t~e connecting channel
4 with the drainage channels 1.
In Figure 2 there are shown two insulating
panels stacked vertically on top of each other. The
panels are laterally offset relatlve to each other such
that their individual drainage channels l are not
aligned with each other. This no longer poses a problem
regarding the drainage of water, because the water
draining down the drainage channels 1 of the upper
panel enters into a connecting channel 4, flows hori-
zontally along this connecting channel 4 until reaching
the nex~ drainage channel 1 of the lower panel ~hrough
which it can flow freely fuxther down. Such lateral
off-set installation of adjoining insulating panels may
also be made on purpose such that during back-filling
of th~ earth, for example, only the individual drainage
channels 1 of the uppermost panel may be filled with
debris (e.g., soil, gravel, and the like) because the
path for such debris to the lower panel is securely
blocked by such off-set arrangement.

R~ferring to Figure 3 there is shown a preferred
cross~sectional shape of a connecting channel 4, which
in this case has a rectangular cross-section. In order
to promote the drainage of water running along a connecting
channel 4, the bottom 6 of the connecting channel 4 may
extend obliquely towards the drainage channels, as
illustrated in Figure 4. Obviously, a large variety of
cross-sectional shapes of the connecting channels 4 is
possible, one further semi-circular shape is illustrated
in Figure 5.
Attentlon is now drawn to Figure 6. The
insulating pan~l of the embodiment shown is an integral
body having stepped side walls. It basically has the
shape of tWG panel bodies 7 and 8 located on top of
lS each o~her such that they are offset in a lateral
direction relative to each other. This will not only
result in a mutual guiding of adjacent panels, but also
prevent foreign bodies, for instance small-sized bodies
of backfill, to enter between the two panels.
The panel surface in which the ~rainage
channels 1 are located is optionally covered by a
web-like material 11, such that the drainage channels 1
are protected from the incursion of foreign materials
into th~ channels which may block the flow of water
along the channels. This covering web 11 may be of any
kind of material as long as it is water permeable.
According to Figures 6 and 7 this covering web or
porous sheet projects over two adjacent sides 7, 9 of
the panel, such that the covering webs 11 of two
adjoining panels overlap each other. The advantage of
this embodiment is that an imperfect alignment of
neighboring or adjacent, respectively, panels cannot
. 31,908-F _5_

have any detrimental effect regarding the entry of
foreign particles. This overlapping design on the one
hand of the edges and on the other hand of the covering
webs can also allow for an a-t least temporary locking
of adjacent panels during installation by any kind of a
sharp pointed o~ject.
