BUILDING ELEMENT AND STRUCTURE
The present invention relates to a precast concrete building element and
structure constructed from such element. In particular, this invention relates
to a dual
faced retaining element which has been designed so that either face can be
used in the
design of the construction of retaining walls, wherein one face of the wall
element gives
the appearance of a dual vertical octagon shape, and the other face of the
wall element
is vertically flat faced, with a 45 degree vertically angled comer on each end
of the wall
element. Through use of such a design, wall constructions which have an inside
or
outside angle of 45, 90 and 135 degrees are possible. The element can also be
used
in the design of the construction of a variety of other projects and
structures, including
foundations, posts and other configurations.
DESCRIPTION OF THE PRIOR ART
Retaining wall blocks and walls, for example, are used in various landscaping
projects and are generally available in a wide variety of styles. There are
numerous
methods and materials which exist for the construction of retaining blocks and
walls,
and such methods can include the use of natural stone, poured concrete,
precast
panels and masonry. Many of these blocks, such as that described and
illustrated in
U.S. Patent No. 5,513,475, have been developed with configurations having
essentially
the same outside surface, that is a rectangular block. A standard cement block
is
rectangular in shape and has two openings with a solid web transversing
between the
two openings. However, use of these types of blocks for the construction of
retaining
wall structures are generally not aesthetically appealing.
Presently, when rectangular cement blocks are used to fabricate walls, the
aesthetics of the wall leave much to be desired, in that essentially only a
straight linear
wall with a vertical surface is created. Generally, only 90 degree comers can
be used
if a tum in the wall is required. Other walls of various angles can be
constructed only
by cutting the comers of the rectangular block to match the desired angle.
However,
this technique is very time consuming in that it requires a skilled mason to
cut each and
every block at the desired angle.

More recently, segmental concrete retaining wall units, which include dry
stacked
individual blocks, have become widely accepted in the construction of
retaining walls.
Retaining walls made from these types of blocks or units can be structurally
sound,
easy and relatively inexpensive to install, and couple the durability of
concrete with the
attractiveness of various architectural finishes available for the concrete
blocks.
Currently, many commercially available blocks are symmetrical and include
parallel
front and back faces and non-parallel, converging side surfaces. The
converging side
surfaces allow the blocks to be stacked and form a predictable pattern for the
retaining
wall. However these types of blocks do not provide for a unique appearance and
configuration with respect to the comers incorporated into the retaining wall.
Accordingly, there is a need for a retaining wall element and system wherein
the
face of the retaining wall, and the corners incorporated into the retaining
wall, have a
more attractive, unique appearance and variable configuration than that
available in
conventional wall constructions. The present invention satisfies this need and
provides
these benefits. In addition, the element described in the present invention
can be used
in the design of the construction of a variety of other projects and
structures, including
foundations and posts.

diagonal sides,
channels and protrusions, thus providing an elevated structure formed of the
elements.
According to another aspect of the present invention there is provided a
method
5 of assembling an elevated structure as described above, wherein the comer
angles are
formed at 45, 90 and 135 degrees respectively.
The building element of the present invention is designed so that either face
of
the element can be used in the design of the construction of structures, such
as
retaining walls, wherein one face of the element gives the appearance of a
dual vertical
octagon shape, and the other face of the element is vertically flat faced,
with a 45
degree vertically angled comer on each end of the element. In a construction
of this
type, essentially, one face of the element does not complete the octagon,
rather a flat
surface extends the length of the two halves. The primary advantage of this
design lies
in its versatility. A user may arrange the stone in a variety of fashions
which result in
a wide ranging finished product, such as a complete wall. Through various
configurations of such a design, arrangements of elements to form wall
constructions
which have an inside or outside comer angle of 45, 90 and 135 degrees are
possible.
The element can also be used in the design of the construction of a variety of
other
projects and structures, including posts and foundations.
Preferably, the element is made of precast concrete. In addition, each element
has a singular groove or channel running horizontally across a substantial
area of the
bottom surface of the element, and which is internally formed on an underside
of the
element. Preferably, the vertical height of this groove or channel within the
element
extends internally to accommodate the entire vertical height of the
protrusion. It is
possible, however, that a shallower internal channel or groove may also be
used. It is
also possible that multiple grooves or channels can be formed on the underside
of each
element, the grooves or channels substantially corresponding in shape with the
protrusions formed on the top surface of each element. The grooves or channels
in
each element can be internally located beneath each protrusion, whereby each
protrusion from one element may be interlocked with a corresponding channel of
another element placed thereon.
In a preferred embodiment of the present invention, there are two protrusions
CA 02479978 2004-09-O1
b
formed on a top surface of each element. Preferably, these protrusions are
round and
button shaped, however, other configurations and shapes can be utilized as
well. The
protrusions are designed to allow each element to lock or connect into the
groove or
channel on the underside of another element placed thereon. In this manner,
building
elements comprising the elevated structure can be stacked straight up in
forming a
complete elevated structure, and increases the strength and durability of the
structure.
When completing a wall construction utilizing the building elements of the
present invention, it is preferable, in constructing the top surface of the
wall, to utilize
a further embodiment of the retaining element of the present invention, which
does not
possess any protrusions on a top surface portion of the element (a "capping"
element)
so as to provide a substantially planar top surface for the structure.
Though generally speaking it is preferable for an elevated structure
constructed
with the elements of the present invention to feature full size elements
wherein one face
provides the dual vertical octagon shape, and the other face of the element is
vertically
flat faced, nevertheless, in a further embodiment of the present invention a
"half"
element may also be used in designing the elevated structure and giving it a
unique
appearance. The entire outer periphery of the "half element comprises an
octagonal
shape, and possesses a channel formed internally on an underside of the
element, with
a corresponding singular protrusion also projecting from a top surface of the
element.
By utilizing a "half' element in constructing an elevated structure, in
combination with
the regular sized element of the present invention, it is possible to place
singular "half
elements" on top of a singular protrusion of a regular sized element at
staggered,
spaced intervals in the elevated structure construction. When, in assembling
the
elevated structure, full sized elements of the present invention are then
further locked
or connected on the protrusion of the "half element, the result is an elevated
structure
construction which, depending upon the interval between placement of the "half
elements", can provide for gaps in the outer surface of the structure, which
enables an
aesthetically appealing, unique configuration.
In a further embodiment, in constructing the top surface of the elevated
structure,
the "half element can be configured to not possess any protrusions on a top
surface
portion thereof, so as to provide a "capping element" to enable the top
portion of the
elevated structure to have a substantially planar surface.
