Abstract

A kerb edging block (10), preferably moulded from a cementitious material, is formed with an internal shoulder located at each of a first pair of opposed edges and a profiled corner (32) on one of a second pair of opposed edges. In use the block is bedded in the ground (34) and a pavement (36) of any known type extends into the top shoulder to abut against the face (24) thereof, while a road (38) is formed to extend into the lower shoulder to abut against the face (16) thereof. A chamfer (32) on another edge of the block (10) faces outwardly of the kerb into the roadway. <IMAGE>

Description

SPECIFICATION Improvements in and relating to kerb edging components This invention is concerned with improvements in and relating to kerb edging components, and particularly such components moulded from a cementitious material.

With different types of roadway conditions and regulations, different designs of kerb edging components are presently produced, and consequently it is necessary for stocks to be held of the various different designed components, leading to the necessary increase in storage capacity and inevitably increased costs. Also it is inconvenient when installing kerb edging to have to work with supplies of different component designs with the inevitable loss of work time involved.

It is an object of the present invention to provide a component for use as a kerb edging which obviates or mitigates disadvantages such as outlined above.

According to the present invention there is provided a component for use as a kerb edging, the component comprising an internal shoulder located at each of a first pair of opposed edges, and a profiled corner on one of a second pair of opposed edges, whereby the component can be used in a selected one of a plurality of desired applications.

Preferably the component is a unitary product formed, for example moulded, from a cementitious material. Alternatively the component can be formed in two parts which may be secured together.

Preferably also the pairs of opposed edges define respective side edges of the component, and adjacent side faces of the component which define each of the side edges extend at substantially right angles to one another, the opposed side faces of the components being substantially parallel. Each of the shoulders may be designed by a pair of adjacent faces which extend at substantially right angles to one another.

The present invention also provides a kerb edging assembly comprising a component as described in any of the three preceding paragraphs and a drainage member on which said component is arranged to be supported, the drainage member extending in use laterally outwardly of one side of the component and defining a drainage channel therebelow.

An embodiment of the present invention will now be described by way of example only, with reference to the accompanying drawings, in which: Figure 1 is an end view of a component according to the invention; Figures 2 to 9 show the component in use in different applications; and Figure 10 is a front exploded perspective view of the component in one application and an associated drainage member.

Referring to Figure 1 of the drawings a kerb edging component is formed as an integral block 10 moulded from a cementitious material. Considering the block 10 to be of substantially rectangular cross-section, each of the first pair of opposed edges is removed to form an internal shoulder. As viewed in Figure 1, a shoulder 12 at a lower edge is defined by adjacent faces 14,16 which extend at substantially right angles to one another, and at right angles to respective side and lower faces 18,20 of the block 10. At the opposed upper edge, a shoulder 22 is defined by adjacent faces 24,26 which again extend at substantially right angles to one another and to the respective upper and side faces 28,30. At the other upper edge the corner is formed by a chamfer 32 and each remaining edge of the block 10 is radiussed or chamfered.

In a first application as shown in Figure 2, the block 10 is located in the same orientation as Figure 1 so that the chamfer 32 faces outwardly of the kerb into the roadway. The part of the block defined by the faces 16, 20,26 and 30 is bedded in the ground 34. A pavement 36 which may be of any known type such as formed by slabs, interlocking blocks or black top, extends into the shoulder 22 on top of the face 26 to abut against the face 24. A road 38 may be formed to extend into the shoulder 12 below the face 14 and abut against the face 16.

In the application as shown in Figure 3 the block 10 is similarly located but the road 38 is formed to abut against the face 18 below the chamfer 32.

Thus the height between the pavement and road reduced.

Referring to Figure 4, the block 10 is turned through 180 . The part of the block defined by the faces 14,18,28 and the chamfer 32 is bedded in the ground 34 so that the block 10 presents the right angled corner defined between the faces 20 and 30 to the roadway. The pavement is laid into the shoulder 12 above the face 14 to abut against the face 16 while the road 38 is laid into the shoulder 22 below the face 26 to abut against the face 24. In Figure 5 the block 10 is positioned as in Figure 4 but the road 38 is laid against the face 30 at a lower part thereof so as to reduce the height of the pavement 36 above the road 38.

Referring to Figure 6 the block 10 is reorientated and turned through 90O clockwise as viewed in Figure 1. That part of the block 10 as defined by the faces 18,24,28 and the chamfer 32 is bedded in the ground 34 so as to present a substantially right angled corner defined by the faces 20,30 into the roadway but with the shorter of the faces 20,30, i.e.

face 20, arranged vertically. The pavement 36 is laid into the shoulder 22 above the face 24 to abut the face 26 while the road 38 is laid into the shoulder 12 below the face 16 to abut the face 14. The height of the pavement 36 above the road 38 is less in this arrangement than in the Figure 4 arrangement. In Figure 7 the block 10 is arranged similarly to Figure 6 but the road 38 is laid against the face 20 at a lower part thereof so as to further reduce the height of the pavement 36 above the road 38.

in Figure 8, the reorientated block 10 is turned through 90 in an anticlockwise direction relative to Figure 1. That part of the block 10 defined by the faces 16,20, 30 is bedded in the ground 34 and presents the chamfer 32 into the roadway but with a shallower angle to the roadway than in the arrangement of Figures 2 and 3. The pavement 36 is laid into the shoulder 12 above the face 16 to abut the face 14 while the road 38 is laid into the shoulder 22 below the face 24 to abut the face 26. Referring to Figure 9, the block 10 is arranged as in Figure 8 but the road 38 is laid against the face 28.

The positioning of the road and the pavement within the shoulders 12,22 defined in the block 10 creates an effective mechanical interlocking arrangement resulting in a mutually supportive structure. This enables the blocks 10 to be laid on a prepared bed of particulate material and sand without the need for haunching and consequently the mixing of concrete on site. The blocks 10 can be laid on the prepared bed and vibrated into position. Also the interlocking arrangement enables the blocks 10 to be shorter and have a lower unit mass than conventional kerb blocks due to the fact that the loading on the blocks need not be distributed over such a length as is necessary with conventional kerb blocks. This in turn means that the blocks are easier to handle, and easier and quicker to lay.Further, displacement and/or subsidence of the blocks is less likely to occur as the blocks are more capable of withstanding the impact of, and overrunning by, motor vehicles.

The length of the blocks 10 is preferably chosen so that when the road or pavement is formed by slabs a modular arrangement is created which can ensure that joints between the adjacent slabs do not align with joints between adjacent blocks, as this would otherwise weaken the structure. For this purpose the blocks can be formed, for example, of a length equal to twice the length of the slabs for a staggered relation. Where interlocking blocks are used to form the pavements or roadways, the kerb blocks can also be dimensioned to be complementary thereto.

It will be appreciated that the same block 10 can be used in any of the various arrangements to suit specific requirements for different types of carraigeways and is designed to comply with many features of the British standard range. The block is dimensioned and of such a length as to be complementary to other components now used to form the pavements or roadways, such as slabs or interlocking blocks.

As shown in Figure 10, when a plurality of the blocks 10 are to be laid end to end, each can be associated with a drainage member 40 which is preferably moulded from a cementitious material and is in the form of a tray of substantially rectangular cross-section. The member 40 has a shallow channel 42 extending longitudinally thereof and towards one side, the channel 42 having an inclined face 44 leading from the base of the channel 42 to an upper surface 46 of the member 40. At the other side of the channel 42 the upper face 46 is arranged to support the adjacent lower face 20 of the block 10 so that the latter provides an overhang for the channel 42.

In use, the road 38 abuts against an end face 48 of the member 40 and the block 10 presents a kerb edging below which is provided the drainage chan nel 42 in the aligned components 40. At each end, the member 40 is provided with a cut-away part 50 in the channel 42 and the parts 50 of adjacent members 40, when the latter are laid together, define a seat for a sealing and jointing component 52 which is of generally U-shaped configuration. The jointing component 52 is postioned with one leg 54 in the space defined by adjacent cut-away parts 50, the base 56 extending upwardly along the face 16 of the block 10 and the other leg 58 extending horizontally below the face 14 of the block 10.It will be appreciated that the block 10 can be used in different applications as previously described and the drainage member 40 with the jointing component 52 can be utilised in any such application.

The kerb edging block is extremely advantageous in that, because a single design can be used in all the different arrangements described above, stocks of only the single component require to be kept, thus making optimum use of machinery for manufacture and storage area. Also where only one design of block is used in installation, the installation is facilitated.

In a modification the kerb edging component may be formed as other than an integral block. For example the component can be formed in two parts which are secured together for use.

Various other modifications may be made without departing from the invention. For example the relative dimensions of the various parts of the component may differ from those described and shown. Haunching may of course be used if desired.
