Description
<Desc/Clms Page number 1>
SYNTHETIC KERBS AND METHOD OF USE Field of invention: This invention relates to synthetic kerbstones. These kerbstones can be used in the construction of roads and pathways.
Background of the Invention: In the construction of roads and footpaths, it is common practice to lay concrete kerbs at the initial stages of a building contract. Typically, a road is constructed relatively early to allow access to the site. The road's sub-base and base course tarmac is-also laid at this stage in the contract to act as a hard-standing and/or a surface for construction vehicles to access the site often heavily laden with building materials and/or waste. The concrete kerbs are therefore susceptible to breakage or often, irreplaceable damage. This can result in kerb replacement towards the end of the contract, prior to the laying of top-course tarmac and hence, extra expenditure may be incurred as overheads for the contractors.
Prior Art: Synthetic kerbstones are known from the patent KR132721Y which describes the use of shock absorbent rubber kerbs each containing two conical holes formed in a row on either side of the centre and a mounting groove cut around the edge. The kerbs described in the Korean patent are to be used in conjunction with a mounting element mounted on the road having conical studs to be pressed into the conical holes and the kerb pressed into the mounting groove fixing the kerb element to the road. These kerbstones are designed for permanent fixture in place.
<Desc/Clms Page number 2>
Brief Description of the Invention: We have determined that an improved method of laying roads comprises the steps of a) placing a set of durable polymeric kerbstones along the borders of the road and laying the sub-base of the road, b) replacing the durable polymeric kerbstones with non-polymeric kerbstones c) laying the top coat of the road.
Our invention also provides a polymeric kerbstone, which has the same dimensions as a conventional concrete kerbstone.
An alternative aspect of our invention provides a polymeric kerbstone having a longitudinal channel.
Detailed Description of the Invention: By means of the invention it is believed possible to reduce the incidence of kerb damage by delaying the laying of the final kerbstones until the final stages of construction. The polymeric kerbstones described herein can support the edges of the road surface in the same manner as conventional kerbstones so as to allow the construction and use of the road during, for example, nearby building works. The polymeric kerbs can be driven over without the possibility of damage to the appearance of the final road. At the end of these building works, the temporary polymeric kerbs are removed and replaced with conventional kerbstones (typically made of concrete or stone). The polymeric kerbs are preferably reusable. In the alternative, the kerbs may be left in place and advantage taken of their resistance to damage on being mounted by vehicles.
Preferably, the polymeric kerbstones are formed from a hard, lightweight, durable rubber or polyethylene compound. Portions of the kerbstone can be made of a lower density polymer material to reduce weight. In a preferred embodiment of the present invention the overall weight of the kerbstone is not more than 25kg. This enables the kerbstone to comply with `one man lift' regulations in the United Kingdom.
Typically the polymeric kerbstones are formed in the precise dimensions of an existing standard concrete half-battered or bull-nosed kerb. Other embodiments of the present invention provide for other chamfered, radiused and/or splayed kerbstones. End faces of a kerbstone may be provided with interlocking fixing elements.
A preferred additional feature on each kerb is the presence of two or more holes running longitudinally through the half-battered kerb and one or more holes running longitudinally through the bull-nosed kerb. The longitudinal holes are believed to improve the shock-absorbency and hence durability of the kerb and also to decrease the weight of the product.
<Desc/Clms Page number 3>
Additionally or alternatively, one or more longitudinal holes allow for the provision or services such as gas, water, electricity, communication and/or drainage. The provision of the, or each, service duct is of particular utility when the kerb is intended for permanent fixture, rather than for temporary usage. Access holes may be provided for the service ducts. Ideally service and drainage ducts are provided independently. End faces of a kerbstone may be provided with coupling elements for one or each longitudinal hole. These can, for example take the form of a socket and spigot connection.
In further preferred embodiments, the kerbstones are provided with holes to allow the insertion of removable quarter-turn handles for easy transportation and installation. Conveniently, the rubber compound to be used is that obtainable from recycled rubber tyres. This is often known as `re-crumb rubber'. Other plastics materials may be employed. The product made in polyethylene is made from either virgin or recycled polyethylene.
In particular embodiments, dyestuffs or pigments are added to enable the kerb to be manufactured in different colours as required. Preferred colours and textures match existing kerbstones.
Preferably the kerbs are formed from a material having a Young's Modulus of between 4 and 100 MPa (mega-pascals) where 4AMPa is equivalent to an IR HD (hardness) value of 60 (arbitrary units).
Examples: The invention will be further described by means of a non-limiting embodiment and with reference to the accompanying drawings.
The kerb is to be designed in the same shape as conventional half-battered and bull- nosed kerbs to precisely the same dimensions as shown in figures 1 and 2.
Figure 1 shows a polymeric kerbstone in the precise dimensions of a conventional half-battered kerb, with an angled chamfer, 1, of either 12.5 or 15 . A preferred additional feature is two or more holes, 2, running longitudinally through the kerb. In further preferred embodiments, the kerbstones are provided with two holes, 3, on the top face, to allow the insertion of removable quarter turn handles for easy transportation and installation.
Figure 2 shows a polymeric kerbstone in the precise dimensions of a conventional bull-nosed kerb and shows an additional feature of one or more holes, 4, again running longitudinally through the kerb. The additional feature, 3 is as described for figure 1.
