PRECAST CONCRETE STONE WITH ANGLED
SIDE WALL SECTION
TECHNICAL FIELD
foool7 The present invention relates to a precast
concrete stone having a base section with straight side
walls, one of which is an angled side wall. The precast
concrete stone can be used as a payer or a retaining wall
precast concrete block. .
BACKGROUND ART
Cooo21 Precast concrete stones are well known in the
art and these are fabricated of various shapes, usually
rectangular in contour or having a zig-zag shape side wall
whereby to interlock with adjacent like stones: It is also
known to have stones of different sizes laid side-by-side
and also at right angles to one another to form a decorative
pavement. It is also known to use precast concrete blocks
with integrated locking formations whereby to construct
retaining walls. These blocks are also of substantially
rectangular contour and may be disposed relative to one
another at right angles to construct walls having
irregularly disposed blocks to resemble real stone. These
precast concrete stones are also roughened or tumbled to
further resemble a real stone.
SUMMARY OF INVENTION
tooo3~ A feature of the present invention is to provide
a precast concrete stone or block formed of a base section
of predetermined thickness and an integrally formed stone
section projecting from an outer face of the base section
and wherein the base section has side wall sections one of
which is an angled side wall section whereby to form stone
pavements or block retaining walls having irregular and
angulated intersecting joints.
tooo4~ Another feature of the present invention is to
provide a precast concrete stone having a base section and a
stone section formed integral therewith with the stone

section recessed from the straight contour side walls of the
base section to form a contour joint portion with at least
one of the side wall sections being an angulated section and
when laid on a ground surface as pavement, it resembles
flagstones of irregular shapes with intersecting angulated
and straight joints.
tooo5l According to the above features, from a broad
aspect, the present invention provides a precast concrete
stone with an angled side wall section and has a base
section of predetermined thickness and straight side wall
sections, one of which is an angled side wall section. A
stone section is formed integral with the base section and
projects from an outer surface of the base section. The
stone section is recessed from at least two adjacent ones of
the straight side wall sections and exposes a top flat edge
surface of the outer surface of the base section about at
least two adjacent flat edge surfaces of the stone section.
The side wall section is adapted to mate with an angled side
wall section of another precast concrete stone whereby
stones can be disposed side-by-side and offset from one
another to obstruct at least some continuous joints between
a plurality of adjacent stones.

DESCRIPTION OF PREFERRED EMBODIMENTS
(o0oisl Referring now to the drawings, and more
particularly to Figure 1, there is shown generally at 10 the
precast concrete stone of the present invention. It is
comprised of a base section 11 of predetermined thickness
and having straight side wall sections 12, with one of the
side wall sections 12' being an angled side wall section.
(000197 A stone section 13 is formed integral with the
base section 11 and projects from an outer surface 14 of the
base section 11. The stone section 13 is also recessed from
the side walls 12 whereby to expose a top flat edge contour
surface 15 all about the stone section 13. The stone
section also has side walls 16 and one of which, namely side
wall 16', is also angulated.
(o0020~ As better seen from Figure 2, the side walls 16
of the stone section 13 have an irregular edge simulating a
real stone. The top surface 17 is also tasted to have an
irregular surface or the surface of the stone after carted

is roughened by roughing devices such as by impact of
rotating chains.
fooo2l~ As shown in Figure 4, other precast concrete
stones are casted as rectangular or square stones 10' having
opposed parallel side walls 22 and end walls 23. The stones
section 13' is spaced from the side wall exposing a top flat
contour surface 15'. The side walls 12 and 22 of the stone
are flat straight side walls whereby when the stones are
laid side-by-side, as shown in Figure 5, the side walls 12
are in flat contact with one another and the contour flat
surfaces 15 form a recess channel or joint 20 in which a
joint filler material, such as sand 19 may be placed whereby
to form a pavement, such as the pavement illustrated at 30
in Figure 6, exposing only the stone sections 13 having
irregular contour edges 16 and 1&'.
fooo22~ As shown in Figure 6, the pavement 30 includes
precast concrete stones 10 as well as precast concrete
stones 10' which are laid side-by-side whereby to form
angled joints 31 as well as straight joints 32. However,
the object of providing a precast concrete stone having at
least one angulated side wall is to provide a pavement
wherein straight joints do not have continuity. That is to
say, straight joints 32 are often intercepted by the stones
to break the continuity of these joints. In the pavement
pattern as illustrated in Figure 6, one of the straight
joints, namely joint 33, is a continuous joint simply to
illustrate what is meant by continuity. The angle side wall
sections 12' redirect a straight joint at an angle, such as
illustrated at 34 wherein straight joint 32 is terminated
and redirected at an angle. These stones 10 and 10' can be
laid either horizontally or vertically but when forming a
pattern the joints are disposed at irregular angles as well
as straight angles. Therefore, the pavement provides the
resemblance of a flagstone-like pavement with some of the
stones having angulated sections resembling fragmented
corners of flagstones. Because these stones 10 can be laid
CA 02459509 2004-03-04
- 5 -
either vertically or horizontally, it can create non-
repetitive patterns throughout very large surfaces. Still
further, the stones 10' are dimensioned to be interposed in
side-by-side relationship with the stones 1.0 to form
workable patterns such as that illustrated in Figure 6.
tooo237 With reference now to Figure 10, there is shown
a precast concrete stone 10" constructed in accordance with
the present invention and which comprises two straight
angulated side wall sections 12". One of these straight
angulated side wall sections could also be disposed in
opposed corners of the stone 10" such as indicated by
phantom line 36. Alternatively, the angle wall section may
be recessed as shown by phantom line 37. Accordingly, it is
not intended to restrict the present invention to an
angulated side wall section as specifically illustrated in
the embodiment illustrated by Figures 1 to 3.
fooo2~7 Referring now to Figures 7 to 9, there is shown
another embodiment of the construction of the precast
concrete stone 10°' and wherein the stone section 13" is
positioned in line or flush with two adjacent side walls 12"
and spaced from the other side walls whereby to expose a top
flat surface 15" which constitutes the complete joint when
two stones are laid side-by-side. Again, the stone section
13" has an irregular contour. However, it is preferable to
fabricate such stones with the embodiment of Figures 1 to 3
in order to have joints of more regular width about the
stones when laid in a pattern such as illustrated in Figure
6. It is also pointed out that the stone sections 13 which
have irregular shaped contour side walls 16 also have their
corners rounded as illustrated by reference numeral 16" to
again resemble more closely a real stone.
fooo251 Referring now to Figure 11, there is shown a
still further modification of the present invention wherein
the concrete stone is used as a retaining 'wall concrete
block. The stone is constructed similar to that illustrated
in Figures 1 to 5 with the exception that the side walls 12
CA 02459509 2004-03-04
- 6 -
and 12' are much thicker and the stones are laid on their
sides. As hereinshown the side wall sections 12" are
extended to form a block. Also, the blocks may be grooved
such as illustrated at 50 on opposed side walls 12" whereby
to receive an interconnecting insert 51 to prevent forward
shifting of the blocks. Such block interconnection is well
known in the art and forms part of one of our patents. As
hereinshown the angle side wall or angled joint 52 forms an
angulated intersecting joint. The stone section 13' also
simulates stones of irregular shape providing the advantage
as heretofore described.
(ooo2s~ It is within the ambit of the present invention
to cover any obvious modifications of the referred
embodiment described herein, provided such modifications
fall within the scope of the appended claims.
