Definitions

  • This invention relates to an edge-restraining device, which can be used with advantage in place of the conventional kerbstones.
  • the device is for edging roads or pathways made up of small element paving.
  • the invention is not limited to this application since it will find use in ornamental gardens, sports complexes, public open spaces, and other situations where an edging of neat appearance, which is also cheap to manufacture and lay, is required.
  • the present invention aims to provide an improved edge-restraining device.
  • an edge-restraining device which includes an elongate upstanding edge-restraining member securely connected to a mesh or mat of geogrid material as herein defined.
  • the edge-restraining member is located where required, and serves in place of conventional kerb-stones, and the mesh or mat is extended as necessary, e.g. in a generally horizontal direction.
  • the road or path surfacing material usually (paving blocks, or occasionally tarmacadam, or any other desired surfacing material) is then laid so that mesh or mat is trapped between a base course and the laying course (usually sand).
  • the mesh or mat, and hence the elongate edge-restraining member is held firmly in position against generally horizontal movement.
  • the edge-restraining member is preferably of synthetic plastics material, and may be extruded for ease of manufacture.
  • connection between the member and the mesh or mat may be made in any suitable way, e.g. by adhesive, by stapling, or by a plastics heat or RF or hot-air welding procedure.
  • the mesh or mat becomes an integral part of the pavement or roadway construction, but is not visible, and the use of this invention obviates the need for the "wet trade” of laying newly mixed concrete to hold or "haunch” kerb stones in position. It also obviates the need for spikes to be driven in, at frequent intervals. Hence edge restraint is substantially simpler, quicker and less expensive than with prior art methods and products.
  • the edge-restraining device may also be used in domestic gardens where durable, easily laid edges of neat appearance are desired.
  • Figure 1 is a perspective view of one example of the invention
  • Figure 2 is a cross-sectional view of the arrangement shown in Figure 1, illustrating its edge-restraining relationship with the laid blocks which will provide a paved surface
  • Figure 3 is a perspective view illustrating an arrangement according to the invention and which permits a non-90° configuration of two parts of an edge-restraining member.
  • an edging device which includes an elongate upstanding edge defining member 10 of synthetic plastics material.
  • This member 10 is L-shaped as seen in cross section, having an upstanding limb 12 and a horizontally extending limb 14.
  • the member 10 may be a plastics extrusion.
  • To the underside of the horizontally extending limb 14 is secured, in a substantially permanent manner, a mesh or mat 16 of geogrid material.
  • geogrid in this context is used to mean any open mesh or perforated mat of textile, synthetic plastics or other flexible material which can be laid between a laying course 18, which is usually sand, and which immediately underlies the surface paving blocks 20 when they are laid, and a base layer or base course 22 which is usually rubble, aggregate, or broken and chipped rocks or stones.
  • a geogrid layer as herein described interlocks to some extent with the material of the base layer. Consequently the geogrid is prevented from making any significant lateral movement. Such movement of the edge-restraining member (which is firmly secured to the geogrid) is likewise prevented.
  • the geogrid mesh or mat 16 is connected to the limb 14 in any suitable manner giving adequate strength and permanency of connection, for example by adhesive, by a plastics welding procedure (in the case of a geotextile material incorporating suitable plastics), or by stapling or other fastening methods.
  • the material known by the Registered Trade Mark "NETLON" and available from the Company of that name may be used for the geogrid 16. In some circumstances, it may be possible to dispense with the sand layer.
  • sand 18 and path or road material 20 e.g. paving blocks as illustrated or tarmacadam or concrete, are laid over the limb 14 see Figure 2, and the geotextile material 16, and one lateral edge thereof is bounded by the upstanding limb 12.
  • the road or path material when laid securely maintains and anchors the geogrid 16 and the limb 14 in position and so ensures the proper maintenance and location of the edge restraining limb 12.
  • edge- restraining member 10 arises when a wheel of a heavy vehicle runs on that part of the road surface closely adjacent to the edge restraining member. With prior art constructions such a stress would often result in deformation or dislodgement of the kerb or equivalent member.
  • the heavy weight of the vehicle transmitted through the wheel and then the paving block and the laying course, enhances the interlock and interengagement between the geogrid mesh or mat and the base layer and so any tendency of the mesh or mat and hence the edge-restraining member to be dislodged is automatically resisted.
  • the edge restraining member 10 may be made in sections of any desired length, for example it may be made in units of one metre length, or two metre length, or any other convenient size. Although in Figure 1 the limbs 12 and 14 have been shown of approximately equal size, the invention is not considered to be limited to any particular size or shape relationship between these limbs. As seen in Figures 1 and 2, a short flange may be provided at the upper edge of the limb 12.
  • FIG. 3 shows a version of the invention in which the elongate upstanding edge-restraining member is required to define an edge which has straight portions which join each other at various angles.
  • the edge-restraining member 110 shown in Figure 3 has parts of its horizontal flange 140 cut away prior to the attachment thereto of the geogrid 160.
  • the resulting recesses are illustrated at 162.
  • the upstanding limb 120 of this member becomes readily deformable by hand and during the laying of an edge-restraining member the member can be bent as desired. In this way the limbs 120 can be made to follow a non-linear or cranked configuration in a horizontal plane.
  • the geogrid 160 is then securely attached to the non-removed parts of the limb 140 in the manner illustrated.
  • one geogrid portion 160A can overlay another 160B.
  • the laying course e.g. sand, is then laid over the geogrid and a suitable road or path surface laid thereon.
  • edge-restraining members 10 or 110 of different shape could be employed if particular technical or aesthetic effects are desired. While the road material has been mentioned as paving stones or blocks, it could equally well be other suitable materials, e.g. concrete or tarmacadam. Other variations and improvements, which would be considered within the scope of the invention, will occur to the man skilled in the art.

Abstract

Un dispositif de retenue de bordure comprend un élément (10) de retenue de bordure allongé et vertical relié à une géogrille (16). Une géogrille est un tapis à grandes mailles ou à perforations ou à orifices, fabriqué à partir d'un textile, d'un matériau en plastique synthétique ou de tout autre matériau flexible, susceptible de s'engager et de s'enclencher dans une certaine mesure avec une couche de base composée de pierraille etc.
