Precast concrete stone with angled side wall section
A precast concrete stone is provided 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 stone can be disposed side-by-side and offset from one another to obstruct a straight continuous joint between a plurality of adjacent stones.
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 paver or a retaining wall precast concrete block.
BACKGROUND ARTPrecast 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 INVENTIONA 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.
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.
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.
BRIEF DESCRIPTION OF DRAWINGSA preferred embodiment of the present invention will now be described with reference to the accompanying drawings in which:
Referring now to the drawings, and more particularly to
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.
As better seen from
As shown in
As shown in
With reference now to
Referring now to FIGS. 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 FIGS. 1 to 3 in order to have joints of more regular width about the stones when laid in a pattern such as illustrated in
Referring now to
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.
Claims
1. A precast concrete stone comprising a base section of predetermined thickness and having straight side wall sections, a stone section formed integral with said base section and projecting from an outer surface of said base section, said stone section being recessed from at least two adjacent ones of said straight side wall sections and exposing a top flat edge surface of said outer surface of said base section about at least two adjacent flat edge surfaces of said stone section, at least one of said straight side wall sections being an angled side wall section adapted to mate with an angled side wall section of another precast concrete stone whereby said stones can be disposed side-by-side and offset from one another to obstruct at least some straight continuous joints between a plurality of adjacent stones.
2. A precast concrete stone as claimed in claim 1 wherein said stone section is recessed from all of said straight side walls exposing said flat edge surface all about said stone section.
3. A precast concrete stone as claimed in claim 2 wherein said stone section has an irregular contour side wall.
4. A precast concrete stone as claimed in claim 3 wherein said stone section has an irregular top surface resembling a stone texture.
5. A precast concrete stone as claimed in claim 2 wherein said base section is at least twice the thickness of said stone section.
6. A precast concrete stone as claimed in claim 2 wherein said stones, when positioned side-by-side, define a recessed joint therebetween formed by adjacent top flat edge surfaces of said base sections of said stones.
7. A precast concrete stone as claimed in claim 2 wherein said precast concrete stone is a paver stone.
8. A precast concrete stone as claimed in claim 4 wherein said stone section has rounded corners and wherein said top surface is a molded embossed top surface.
