Definitions

  • This invention relates to access floor structures and to a floor panel for such a structure.
  • An access floor structure provides a floor surface spaced above a solid, e.g. reinforced concrete, floor of a building to provide a cavity in which electrical cables and other services can extend concealed from view.
  • a solid, e.g. reinforced concrete, floor of a building to provide a cavity in which electrical cables and other services can extend concealed from view.
  • Such structures are particularly useful in computer rooms where the underfloor plenum may also be used for air conditioning purposes.
  • the floor structure comprises pedestals with feet resting on the solid floor and upper ends supporting the floor panels either directly or indirectly by way of a grid of support beams or stringers.
  • the floor panels require good structural and sound and thermal insulation properties. Originally such panels were made for example of chipboard covered with carpet but although such composite wood materials perform well under compressive loads they soon fail under tensile or sheer stresses. Steel panels, on the other hand, although having good structural properties as well as wear and fire resistance, do not provide adequate sound and thermal insulation.
  • One improved embodiment of steel panel has a lower skin with circular depressions on its upper surface spot welded to a planar upper panel with the enclosed space filled with a cementitious material.
  • each floor panel comprises a plane rectangular laminar panel member formed of a wood composite material.
  • a sheet of metal is mounted in touching contact with the lower surface of the panel member and has channels formed therein extending across the full width thereof.
  • Metal support beams are mounted on opposite sides of the panel and are connected to and extend transversely of the channels in the sheet of metal so that the load on the panel is carried by the channels and the support beams to the pedestal units at the corners of the panel.
  • This known floor panel is expensive to manufacture because it consists of numerous components requiring separate fabrication and subsequent manual assembly.
  • an access floor structure comprising one or more panels according to the second aspect of the invention and support means, for example pedestal units, for supporting the panel(s) either directly (and preferably at the corners thereof) or indirectly via a framework of stringers.
  • a floor panel for an access floor structure comprising a structural pan member having a floor and side walls, a laminar panel element (preferably of wood composite material) fitted in said pan member and resting on protrusions from the floor thereof, and a cover panel fixed (as by adhesive bonding) to said laminar panel element (and preferably to the side walls of said pan member), the floor protrusions being so arranged as to increase the strength of the panel on two mutually perpendicular axes thereof.
  • a laminar panel element preferably of wood composite material
  • the access floor structure comprises one or more structural floor panels raised above a solid, e.g. reinforced concrete, floor of a building by pedestal units (not shown) arranged either to support each rectangular panel at the four corners thereof or, alternatively, to support a grid of stringers on which the floor panels are located.
  • pedestal units not shown
  • Such access floor structures are well known and require no further description.
  • the floor panel illustrated in the drawings comprises a plane rectangular laminar panel member 1 made of a wood composite material, preferably chipboard.
  • the panel 1 fits snugly into a galvanised steel pan 2 with a planar floor 3 interrupted by generally triangular lands 4 arranged symmetrically around a central circular land 5 to produce the appearance of a wheel hub and spokes in the underneath view shown in Fig. 2.
  • the triangular lands 4 have grooves 6 parallel to the adjacent pan edge.
  • Circular lands 4a are provided at the corners of the pan 2.
  • the underside of the panel 1 is bonded by adhesive (e.g. a structural epoxy adhesive) to the lands 4, 4a
  • adhesive e.g. a structural epoxy adhesive
  • the side walls 7 of the metal pan are stepped outwardly and have at their upper edges out-turned lips 8 which are overlapped by a top skin 9 of galvanised steel bonded by adhesive (e.g. a laminating adhesive) to the panel 1 and welded to the lips 8 to complete the structure.
  • the steel pan 2 may be fabricated in a single pressing operation and in a modified embodiment the top skin 9 is formed integrally with and alongside the pan 2 and then cut off before being laminated to the chipboard panel 1 which is then inserted into the pan 2 which has previously been treated on the lands 4 with the structural adhesive (which may alternatively or additionally be applied to the free surface of the panel 1).
  • the lands of the metal pan may be arranged differently; also, the chipboard may be replaced by another material (although a wood composite is preferred).
