Abstract
A set of cast concrete paving slabs is laid in a pattern side by side and end to end to cover an area to be paved. Each of the slabs members has side and end spacer abutments to hold an adjacent slab member at a predetermined spacing.
Each of the slabs has a longitudinal slot in the upper surface defining a false joint parallel to the sides so as to divide the upper surface into parallel strips.
There are different types of slabs some with both strips divided by transverse slots and some with only one strip with a slot. This forms in the finished product apparent strip pieces of many different lengths to simulate wood planks. Each of the parallel strips has a molded upper surface defining a series of wavy lines recessed from other parts of the upper surface and dyed darker than the remaining part of the slab thus simulating a wood grain appearance.

DETAILED DESCRIPTION
In figures 1 to 4 is shown the four slabs of a set of cast concrete paving slabs arranged to be laid in a pattern to cover an area to be paved. In Figure 8 the slabs of Figures 1 to 4 are shown laid in patterns where the different shapes combine to provide a pleasing effect as described in more detail hereinafter.
The slabs are shown in plan view in Figures 1 to 4 and 8 so that the various shapes of the slabs can be readily determined.
The construction of the slabs is better shown in Figures 5, 6 and 7 where each slab 10 has a bottom surface 11 for laying in the area and an upper surface 12 for presenting for viewing when laid. Each slab has a first side 13, a second side 14 parallel to the first side, a first end 15 and a second end 16 so that the slab can be laid side by side and end to end to cover the area to be covered by the pattern of slabs.
Each of the slabs has a series of rectangular spacer abutments 17 cast into the sides so as to be attached thereto along the sides and ends so as to contact the abutment of an adjacent slab and hold the adjacent slab member at a predetermined spacing to form a spaced joint therebetween. The abutments are
7 recessed from the top surface 12 and form a layer of constant thickness on the side or end surface of the slab.
Each of the slab members has a longitudinal slot cast into the upper surface defining a false joint and extending along the length of the slab member parallel to the sides 13 and 14 so as to divide the upper surface into a pair of parallel strips 20 and 21. The slot 18 mimics the space between two of the slabs as defined by the spacer abutments so that the depth of the slot is approximately equal to the spacing of the abutments from the top surface and the width of the slot is constant and approximately equal to the thickness of the two abutting abutments.
Each of the slabs is arranged so that the two parallel strips have first ends 15A and 15B of the strips 20 and 21 at the first end 15 of the slab member which are longitudinally offset and symmetrically the second ends 16A and 16B
at the second end 16 are longitudinally offset by a distance equal to a distance of the offset of the first ends. These longitudinal offsets are the same at the ends of the same slab and are equal to the distance of all the other slabs of the set.
In addition, at least one of the strips of each of the set of slabs shown in Figures 1 to 4 has at least one slot in the upper surface defining a false joint and extending transverse to the length of the slab member at right angles to the sides so as to divide the upper surface into a plurality of end to end strips. Thus the slab of Figure 1 has a slot 25 in the strip 20 and the strip 21 is continuous. Thus the slab of Figure 2 has a slot 26 in the strip 21 and the strip 20 is continuous.
Each of the slab members has a longitudinal slot cast into the upper surface defining a false joint and extending along the length of the slab member parallel to the sides 13 and 14 so as to divide the upper surface into a pair of parallel strips 20 and 21. The slot 18 mimics the space between two of the slabs as defined by the spacer abutments so that the depth of the slot is approximately equal to the spacing of the abutments from the top surface and the width of the slot is constant and approximately equal to the thickness of the two abutting abutments.
Each of the slabs is arranged so that the two parallel strips have first ends 15A and 15B of the strips 20 and 21 at the first end 15 of the slab member which are longitudinally offset and symmetrically the second ends 16A and 16B
at the second end 16 are longitudinally offset by a distance equal to a distance of the offset of the first ends. These longitudinal offsets are the same at the ends of the same slab and are equal to the distance of all the other slabs of the set.
In addition, at least one of the strips of each of the set of slabs shown in Figures 1 to 4 has at least one slot in the upper surface defining a false joint and extending transverse to the length of the slab member at right angles to the sides so as to divide the upper surface into a plurality of end to end strips. Thus the slab of Figure 1 has a slot 25 in the strip 20 and the strip 21 is continuous. Thus the slab of Figure 2 has a slot 26 in the strip 21 and the strip 20 is continuous.
8 In Figures 3 and 4, each of the strips 20 and 21 has one slot 27, 28, 29, 30 in the upper surface defining a false joint and extending transverse to the length of the slab member at right angles to the sides so as to divide the upper surface into two end to end strips. It will be noted by comparing the four figures that the slot 25 is spaced from the end 15A by a different distance than the slot 26 from the end 15B. Also the slots 29 and 30 are spaced from the ends 15A and 16B by a different distance than the slots 27 and 28. This arrangement forms the strip portions defined by these false joints to be of different lengths, which provides a very varied appearance in the finished assembly as shown in Figure 8. Thus in Figure 8 the four above defined slabs are used in various location through the layout with each of the four marked by shading.
Each of the parallel strips of the slabs has a molded upper surface defining a series of wavy lines 40 recessed from other parts of the upper surface and simulating a wood grain appearance. The recessed wavy lines as they simulate the lines in wood grain form an array of generally parallel peaks 41 and valleys 42 where the valleys 42 are recessed from the surface 12.
The cast concrete contains a dye which colors it as close as possible to the brown wood color and the concrete material in the peaks 41 contains a dye 43 in the concrete which is different from the dye 44 in the other parts of the upper surface. Typically the dye 44 extends through the whole of the slab. Typically the dye 43 in the recessed wavy lines 40 is colored in contrast to that of the other parts, which could be lighter or darker. The different dye 43 in the recessed wavy lines is

The different dye 43 in the recessed wavy lines is
9 provided only in the concrete in the area of the recessed wavy lines 40 so that the remainder of the paving slabs is of a common color.
As shown in Figures 1 to 4, the simulated wood grain appearance of each of the strips of each of the slab members of the set has a pattern which is different from that of the others. Thus when assembled as shown in Figure 8, the different lengths of the strips and the different patterns in the strips provides a particularly attractive appearance particularly effectively simulating the appearance of a wood floor.
In order to provide an effective wood grain appearance, the recessed wavy lines have a depth of recess from the remainder of the upper surface which is in the range 0.1mm to 2.75mm.
