Definitions

  • This invention relates to flooring systems and more particularly to false flooring systems suitable for installation of services thereunder or therein:
  • EP-A-0 108 282 corresponding to United States Patent Specification No. 4573299 entitled Floor Covering Article provides a matrix base for a false floor which includes a plate like upper surface integral with the base elements. This article requires that services first be laid down on a floor surface and then the upper surface with the integral base elements laid down to provide a false floor. Some difficulty occurs in positioning the services so that they do not interfere with the base elements and in fact these systems are particularly difficult to use.
  • a false floor support unit is characterised by those features set out in the characterising portion of claim 1.
  • an attachment means on the frame arrangement to enable the positioning and retention of services, cabling and duct work.
  • the attachment means may for instance comprise an extension from the frame arrangement about which cable ties may be secured.
  • post extension means mountable on each post, whereby to increase the length of the respective posts and hence the volume of voids produced there-between.
  • the rigid arms may be positioned adjacent the base of each of the posts and extending between the bases of the post, such that the services, cabling and duct work may be laid in the voids over the arms.
  • the location means to locate a section of floor may comprise a rim extending around the peripohery of the unit to define a space there-between into which a flooring panel may be received and to define the void therebelow.
  • the location means may comprise a peg extending from one of the posts on each false floor support unit, the post to be received in an aperture in a flooring panel to thereby positively locate the flooring panel.
  • the unit may comprise a central post, three further posts, with the four posts arranged in a first square grid arrangement, the posts being interconnected by a frame arrangement, three unit interconnecting means with the three unit interconnecting means and the central post arranged in a second square grid arrangement having a grid spacing substantially the same as the grid spacing of the first grid arrangement, the first grid arrangement being on an opposite side of the central post from the second grid arrangement, the unit interconnecting means comprising the means to interconnect the unit to adjacent units and the three unit interconnecting means joined to each other and to the central post by the frame arrangement.
  • the frame arrangement may comprise rigid arms extending between adjacent posts and unit interconnecting means.
  • the invention may be said to reside in a false floor arrangement comprising a plurality of false floor support units as defined above, each unit being interconnected to adjacent units by means of the connection means and a plurality of flooring panels on an upper surface of the post, the location means being received in apertures in the flooring panels to positively locate the flooring panels on the posts.
  • a false flooring unit which can be used as a series of separate units on a floor with flooring panels laid over the units, with the flooring panels either being of a size to extend over two or more of the units or a size to extend only over one unit. Beneath the flooring panels is defined a space or voids, access to which may be maintained by lifting a flooring panel.
  • the length of the posts may be relatively short, perhaps in the order of 20-50 millimetres but this is sufficient to provide space for services such as electricity, telephone and computer wiring to run. Where greater volume of cavity is necessary to provide for instance for gas or plumbing or air conditioning refrigeration ducting, then the post extension means as discussed above may be used to extend the posts to a total length of perhaps 100 millimetres.
  • the edge may make a tray structure and hence the top of the edge may provide part of the final false floor surface when the flooring unit is fully installed or alternatively some embodiments may have a very low edge with the flooring member having a rebate to fit over the low edge so that no edges of the support unit may show between the flooring members.
  • the false flooring unit according to this invention may be constructed from wood or metal or plastics material by any of the known manufacturing techniques. These may include injection moulding of thermosetting or thermoplastics materials with suitable fillers as desirable or may comprise die casting from metal such as aluminium or zinc or they may be fabricated from wood or metal. Alternatively the units may be manufactured from dough moulding compound or sheet moulding compound with suitable press arrangements to press out the desired shapes.
  • the flooring panel above the unit may be made substantially from wood, or steel or plastics material as desired and may be provided with an existing grid of apertures for passing services through the panel from the floor voids to a required position or they may be of such material that holes can be drilled in any desired position.
  • the flooring panels may be provided in a finished condition with a polished wood top or vinyl or any other suitable top surface or may have laid there-upon carpet squares or carpet or some alternative floor material.
  • the edges of the panels may be protected by plastics edging and non-metal panels may be encased in a sheet steel or an aluminium finish.
  • the false flooring units may be provided with apertures to enable fastening screws to fasten the false flooring members to an existing floor or may be adhered by any known adhesive suitable for the purpose.
  • Each of the posts may be provided with some form of shock absorbent padding such as an elastomeric pad and such an elastomeric pad may assist with the taking up of any minor variations in floor level so that the resultant false floor can be made level and will be evenly based.
  • shock absorbent padding such as an elastomeric pad and such an elastomeric pad may assist with the taking up of any minor variations in floor level so that the resultant false floor can be made level and will be evenly based.
  • a flooring unit according to this invention may be made of any suitable dimensions and in one preferred embodiment a unit may be of a size of 600 millimetres square with a height of 48 millimetres. Alternatively a unit having a module size of 300 millimetres may be used with the unit having a thickness of 28 millimetres.
  • a feature of this invention is that by having a plurality of posts to support the undersurface of each floor panel, rather than pedestals at the corners of larger and thicker panels, is that the thickness and strength of the floor panel can be reduced and economies made in the component parts of the invention.
  • the posts may be spaced at 150 millimetre centres but with 50 millimetre diameter posts the unsupported distance between posts is only 80 millimetres.
  • a floor panel thickness of about 18 millimetres has proved to be quite acceptable in accordance with Australian Standards for Dead and Live Loads in buildings.
  • ramped flooring unit to place around the periphery of a false floor region to raise an existing floor to the height of the false floor, particularly at entrances and lift doors and the like.
