Abstract

An arrangement whereby an additional concrete, or other suitable material, part (shoe) is fastened to an existing in situ concrete kerb, edging or channel or similar purpose part used in road or pedestrian way construction, to alter its height and profile to suit the new relaid surface of the road or pedestrian way adjacent. Thus a half battered concrete kerb 1, set in concrete 2, with original road and way surfaces 3 and 4 can have a shoe 5 attached to it enabling the road and way to be relaid, 6 and 7, without removing and resetting the kerb to a higher level.

Description

KERBS AND EDGINGS AND CHANNELS F R-R ADS AND PEDESTRIAN WAYS.

This invention relates to concrete kerbs and edgings and channels for roads and pedestrian ways.

Many roads and pedestrian ways have concrete kerbs and edgings and channels.

Sometimes a road has pedestrian ways aiongside but separated, more often a road has akerb which is also the boundary and edge to a pedestrian way or other hard surface which would then have another kerb or edgingto form the other boundary.

In case of pedestrian ways which are seperate to roads, edgings are used to delineate the path, help in the construction of the path and control the surface water.

Whatever the concrete edging or kerb,they are normally set into, and supported by concrete and then further supported by the materials used in the construction of the road or pedestrian way.

When aroad or pedestrian way requires renews due to wear or damage, it is often advantageous and economical to resurface it such that the finished surface is higher than the original worn surface,and to facilitate this situation it is usually necessary to dig up the kerb or edging tcctether with its concrete hatching and reset it, or a similar new part to a higher level to suit the new higher road or way surface.

The necessity of digging up and resetting the kerb or edging has several important disadvantages concerning cost, pedestrian and road construction operative safety, road user inconvenience and delay expense, construction authority use of plant and operative resource and also it effectively dictates the sequence of events in reconstructing the road or way and delays final surfacing.

It is an object of the present invention to provide an arrangement whereby an additional concrete I or other suitable material, part (referred to hereinafter as a " shoe") is fastened to the existing in situ concrete kerb or edging to raise and or alter its profile to suit the new repaired adjacent road, pedestrian way or other hard surface.

The shoe is fastened to the in situ kerb by adhesive bonding or mechanical means such as bolting, screwing or clamping and is made in suitable, handleable lengths.

In cross section the shoe may be rectangular with some corners radiused or chamfered or rectangular with one or more faces angled and with some corners radiused or chamfered or it may be in the form of an L or angled L or again it may be in the form of a U or angled U.

The face of the shoe in contact with the in situ concrete kerb, edging or channel may be flat or shaped to suit the profile of the aforesaid kerb, edging or channel.

There are many designs of concrete kerbs, edgings and channels some of which are specified in BS 7263 and are described by such terms as half battered, bullnosed, 45 degree splayed (kerbs), round top, flat top, bullnosed, chamfered (edgings), and square, dished, bullnosed, motorway (channels). Each of these designs is available in straight and curved lengths and also matching corner parts known as quadrants and angles.

Each of these designs and parts, whether specified or not in BS, can be provided with a shoe according to this invention, together with all other necessary matching parts.

- The invention will now be further described with reference to the accompanying drawings, in which: Figs la, ib, and ic show cross sections of some designs of (a) kerbs, (b) edgings and (c) channel installations.

Figs 2a, 2b, and 2c show cross sections of kerb, edging and channel installations with shoes attached.

Fig 3, shows a cross section of a type of kerb with one design of shoe attached.

Fig 4, shows a cross section of a type of kerb with a 2nd embodiment of a design of shoe attached according to the invention.

Fig 5, shows a cross section of atype of kerb with a 3rd embodiment of a design of shoe attached according to the invention.

Fig 6, shows a cross section of a type of erb with a 4th embodiment of a design of shoe attached according to the invention.

- Referring now to fig la, this shows a cross section of a typical kerb in situ in a road and pedestrian way configuration.

The kerb 1 is set into concrete haunching 2 with road layers 3 and pedestrian way layers 4.

Referring no-* to fig ib, this shows a cross section of a typical edging in situ in a pedestrian way and soil configuration.

The edging 1 is set into concrete haunching 2 with pedestrian way layers 3 and soil or similar 4.

- Referring to fig ic, this shows a cross section of a typical channel in situ in a road and drainage area configuration.

The channel 1 is set into concrete haunching 2 with road layers 3 and drainage area or other hard standing 4.

- Referring now to fig 2a, this shows a cross section of a typical kerb in situ in a road and pedestrian way configuration (as in fig la) with kerb 1 set into concrete haunching 2 with original road surface 3 and original pedestrian way surface 4 and with a shoe 5 to this invention attached to the in situ kerb with a layer of adhesive 8 and the new relaid road surface 6 and the new relaid pedestrian way surface7.

- Referring now to fig 2b, this shows a cross section of a typical edging in situ in a pedestrian way configuration.

The edging 1 is set into concrete haunching 2 with original pedestrian way layers 3 and original soil or similar 4, also with a shoe to the invention 5 attached to the original in situ edging and the new relaid pedestrian way surface 6 and new soil surface 7.

- Referring to fig 2c,this shows a cross section of a typical channel in situ in a road and drainage area configuration or in situ in any hardstanding which is used for any purpose.

The channel 1 is set in concrete haunching 2 with the original hardstanding surfaces at 3 and 4 and also with ashoe to this invention 5 attached to the original in situ channel 1 with a layer of adhesive 8 and the new relaid hardstandingsurfaces at 6 and 7.

- Referring now to fig 3, this shows a typical kerb with a first embodiment of a shoe to this invention. The in situ kerb 1 has the shoe 2 adhesive bonded in place 3 with the height of the shoe made to suit the thickness of the new laid surfaces adgoining 4.

- Referring now to fig 4, this shows a typical kerb with a second embodiment of a shoe. The in situ kerb 1, has the shoe 2 adhesive bonded in place 3 with the thicknesses and lengths and profiles of the shoe 4 and 5 made to suit the profile of the kerb and the new relaid surfaces adjoining 6.

- Referring now to fig 5, this shows a typical kerb with a third embodiment of a shoe to the invention. The in situ kerb 1, has the shoe 2 adhesive bonded 3 in place, with the thicknesses and lengths and profiles of the shoe 4 and 5 made to suit the profiles of the kerb and the relaid surfaces adjoining 6.

- Referring now to fig 6, this shows a typical kerb 1 with a fourth embodiment of a shoe to the invention. The in situ kerb 1, has the shoe 2 adhesive bonded 3 in place with the thicknesses and lengths of the shoe 4 and 5 made to suit the profiles of the kerb and the relaid surfaces adjoining 6.

Claims

What we claim is 1. An arrangement whereby an additional concrete, or other suitable material, part (shoe) is adhesive bonded or mechanically fastened by screw, clamp or suchlike device to an existing in situ concrete kerb, edging, channel or similar function part of whatever shape which is forming a boundary or separating edge to a concrete, paved or asphalt type material road, pedestrian way or edge area, orcombination of same, to modify or raise the effective height and or profile of the in situ kerb, edging, channel or similar function part to suit the new relaid or resurfaced adjacent road, pedestrian way or edge area to which the aforesaid kerb, edging, channel or similar function part is forming a boundary or separing edge.
2. An additional concrete, or other suitable material, part (shoe), which is fastened to an in situ concrete kerb, edging or channel or part of similar function substantially as described herein with reference to figures 2a, 2b, 2c and 3, 4, 5, and 6 of the accompanying drawings.
