TITLE
MODULAR RETAINING WALL SYSTEM FOR FACADE
TECHNICAL FIELD
[0001] The present disclosure relates to building blocks such as
cementitious
blocks and the like. More particularly, but not exclusively, the present
disclosure relates
to modular retaining wall system for façade.
BACKGROUND
[0002] Retaining walls are structures designed to restrain soil
to a slope that it
would not naturally keep to. These walls are usually a freestanding structure
without
lateral support that lean along the slope of the soil or along the vertical
fill between the
soil and the wall. Retaining walls are used to bound soils between two
different elevations
often in areas of terrain possessing undesirable slopes or in areas where the
landscape
needs to be shaped for more specific purposes. A retaining wall is a structure
that resists
the lateral pressure of soil, when there is a desired change in ground
elevation that
exceeds the angle of repose of the soil. In many cases, it is desired to build
a façade to
cover the retaining wall for aesthetic purposes. The façade sometimes has a
sloped
appearance due to the sloped configuration of the retaining wall along the
slope of the
soil or fill. There are many time consuming, labor intensive, difficult and
cumbersome
building techniques to minimize the sloped appearance of the façade. Many of
these
building techniques are avoided due to costs and difficulty and as such, a
less than
desirable façade is produced.

inserting it into
the top opening 31 of the slot 30 and sliding it downwardly within the slot at
a desired
height within the slot 30. More specifically, the flaps 94 of the first
section 88 engage the
side walls 72 of the spaced apart fingers 58 defining the slot 30. The flaps
92 engage
side walls 73 as well as shoulders 74 to be wedged therein against forward
displacement
yet allowing vertical slidable displacement along the slot 30.
[0065] Figure 7E shows that a pair of connectors 16 can be connected
together
by a fastener through their aligned respective apertures 84, thereby extending
the length
of the connector element 16.

22U and 22L shown in Figure 9B.
[0067] Turning now to Figures 5, there is show a connector 160
having a rear
portion 162 with a tab 164 for being mounted within the slot of a rear
supporting block 22.
In this example, the slot 30 can have a circular configuration as shown in
Figure 2 for
example. The tab 164 extends from a sleeve element 166 via an extension 168.
The
sleeve element 166 includes an opening for receiving the main body insert 170
of the
connector 160. The main body insert 170 includes apertures 172 along its
length. The
user may cut the main body insert 170 in order to shorten it. In an

different
CA 3007399 2018-06-06
15
configurations of a slot 30' of a block 22'. Moreover, the distance between
the leading
edge 267 of the extension 266 and the leading edge 269 of the tab 268 can be
adjusted,
for example, by a distance of Omm shown in Figure 6A, by a distance of 22mm in
Figure
6B, by a distance of 10mm shown in Figure 6C. Of course, other configurations
can
provide other distances as the skilled artisan will readily appreciate.
[0069] In Figures 8A to 8B, there is shown different
arrangements of
interconnected blocks 220 which are shown to have flat non-grooved top and
bottom
surfaces.
[0070] Turning back to Figure 1, the stacked blocks 22 stacked
vertically along
the slope of the soil S and the fact that the connectors 16, 160 and 260 can
be connected
to a façade block 24 at different lengths of the connectors provides for
providing a
generally vertically straight façade F of the façade wall structure 14 defined
by the front
faces 32 bocks 24.
[0071] Figure 1 shows a wall structure 10 comprising a lower
block 12A and
an upper block 12B stacked thereon as is known in the art. As is also known in
the art,
blocks 12A and 12B have respective front façade faces 13 (see Figure 3A),
respective
rear faces 14 (see Figure 3A), top 15 and bottom 17 end, and opposite lateral
sides 19.
[0072] As is also known in the art the respective front façade
faces 13 of
stacked blocks 12A and 12B define the front façade surface 130 of the wall
structure 10.
As is also well known, the top end 15 of the lower block 12A receives the
bottom end 17
of the upper block 12B when stacked thereon. The rear surface 14 (see Figure
3A) of
each respective block 12A and 12B includes a connective element 16. The
connective
element 16 is shown here in the form of a groove having a first groove portion
16A and a

second rearward groove portion 16B. The first groove portion 16A has a
rectangular-like
configuration and the second groove portion 16B has a circular-like
configuration.
[0073]
With respect to Figures 10, and 12A-12C, and 13A there is shown a
connector 318 which connects to the rear façade surface of the wall structure
310 and
thus acts as a rear connector. A rear connector 318 is mounted to the rear
surface 311
of the wall structure 310 formed of blocks 312 which defines a front façade
313. More
specifically, the connecter 318 is mounted to the rear surface 314 of the
upper block
312B. Of course, in another embodiment the connecter 318 can be mounted to the
lower
block 312.
[0074] The connector 318 includes a main elongate body 320, a first portion
322 thereof extending from the body 320 and an opposite second portion 324
thereof.
The first portion 322 provides for connecting to a connective element 316
(shown here in
the form of a groove) of a block 312. In the example shown here, the first
portion 322 is
a protrusion including a rectangular arm 322A and a circular head 322B which
.. respectively connect an outer groove portion 316A and an inner groove
portion 316B of
the groove 316. The circular head 322B includes an insert 323 for being
received by an
indentation 325 formed about the groove portion 316B. The second portion 324
is a
protrusion including an arm 324A extending from the body 320 carrying a
rectangular
head 324B. The rectangular head 324B includes an upper tab 324Bi and a lower
tab
324Bii. The main body 320 includes a longitudinal groove defining a rail
326 for
removably receiving a slider 328 of the first portion 322. In this way, the
first portion 322
can be selectively adjusted about the vertical length of the body 320.
[0075]
With reference to Figures 13A-13B and 14-18, there is shown a
