Definitions

  • This invention relates to reinforcement mesh made from plastics material.
  • Plastics mesh reinforcement concrete has been disclosed in Australian Patent Specification 62016/96 and describes a mesh in the form of sheets having square holes and in the form of a lattice as shown in the preferred embodiment.
  • the purpose or advantage of use of the plastics mesh is that it can be cut with a jigsaw and would be quicker to install than conventional wire mesh wherein strands of wires are welded to each other.
  • US Patent 4,618,385 which refers to the use of plastics mesh for reinforcement of concrete.
  • the mesh is formed from main continuous strands of greater cross section than minor strands of smaller cross section with the minor strands extending through the main strands.
  • the slab When reinforcement is required for structural reasons, the slab will more than likely require the use of high tensible steel bars as well as fabric mesh which may be cut to required size on site.
  • Fabric mesh uses wires of varying diameters, i.e. from 6 to 8mm. In applications requiring heavy reinforcement, there may be utilised two sheets of fabric mesh located top and bottom of the slab.
  • the mesh fabric may be supported from beneath at regular intervals by pad stones, which are often broken pressed concrete flagstones or "bar chairs” which are purpose made plastics or steel supports.
  • pad stones which are often broken pressed concrete flagstones or "bar chairs” which are purpose made plastics or steel supports.
  • bar chairs which are purpose made plastics or steel supports.
  • each of the "bar chairs” as they are known in the building industry are separate from the mesh fabric.
  • US Patent 6,282,860 which describes a bar chair having a body in the form of a ring or disk or a rectangular body having a continuous side wall or frame having a plurality of recesses located in an upper surface of the side wall or side frame to retain a corresponding number of steel bars of a reinforcement mesh.
  • US Patent 3,950,911 which describes reinforcing mesh which is self supporting in the sense that intersecting bars of the mesh may each be provided at appropriate locations with angular bent ends which space the mesh above the ground.
  • the angular bent ends of each steel bar of the steel mesh fabric may replace the conventional bar chairs which are referred to above.
  • the invention therefore provides reinforcement mesh having intersecting filaments made from plastics material which are provided with a plurality of integral supports which elevate the filaments above the ground or other suitable support surface.
  • Each integral support is suitably located at points of intersection of the filaments although it is stressed that while it is preferred to have all points of intersection of the mesh provided with an associated integral support that this is not essential and that each support may be provided at selected or desired intersection points.
  • the mesh for use in the invention may have filaments formed from any suitable plastics material which includes high density polyethylene (HDPE), low density polyethylene, polypropylene and copolymers of HDPE and polypropylene, polyesters and polyamide.
  • HDPE high density polyethylene
  • low density polyethylene polypropylene and copolymers of HDPE and polypropylene
  • polyesters and polyamide polyesters and polyamide.
  • the mesh may comprise filaments which have the same diameter or have different diameters as described in US Patent 4,618,385.
  • the filaments may be welded to each other or a smaller diameter filament may extend through a mating aperture in the larger diameter filament as described for example in US Patent 4,618,385.
  • each filament may be circular as will be apparent from reference to the term "diameter" above it is also possible that each filament may be square, polygonal, rectangular, triangular or any other suitable cross sectional shape.
  • the mesh of intersecting filaments may each have a plurality of integral supports wherein each support in one embodiment may comprise a leg or stem having at a free end therefore an enlarged foot or base.
  • each leg may have any suitable cross section such as round or other suitable cross sectional shape as described above for each intersecting filament.
  • the foot may also have preferably a plate like shape which may be round, square, rectangular or polygonal. Alternatively the foot may be conical, cylindrical or spherical.
  • each support may comprise a frame or body having a plurality of legs or uprights optionally interconnected by webs and also having a foot as described above.
  • FIG. 1 A third embodiment of the invention wherein there are provided overlapping layers of plastics reinforcing mesh.
  • Such layers may be attached to adjacent layers by any suitable attachment means such as ties or fasteners but preferably such attachment means includes the use of integral clips or sockets which form part of each layer of plastics mesh.
  • bar chair assemblies which include a base component which is locatable on the ground or other suitable support surface and one or more upper components attachable or locatable in the base component which ensure that the layer of mesh is located at a desired height above the support surface.
  • FIG 1 is a perspective view of reinforcement mesh constructed in accordance with the first embodiment of the invention.
  • FIG 2 is a perspective view illustrating the bar chair assemblies described above as well as the use of integral clips or sockets described above;
  • FIG 3 is a perspective view of the attachment between the base component and upper component of the bar chair assemblies;
