Definitions

  • This invention relates to a panel assembly and a method of installing same and more particularly although not exclusively to such structures which are used for forming a floor, wall or ceiling in which electric cables, telephone wires, central heating pipes, etc., are located of the floor therebehind.
  • each floor comprises a rough concrete base which is permitted to set and is subsequently substantially levelled by laying over it a sand and cement screed in which cable trays are embedded on a 1.8 m grid, for example.
  • the flooring is then finished by laying down flooring tiles of a plastics material, for example.
  • a computer flooring which consists of a plurality of wood or metal panels of sides usually of 600 mm with adjustable legs on a lower side to define a space between the panels and the usual flooring.
  • VDU cables of a computer are normally randomly placed in the space between the wood or metal panels and the usual flooring.
  • Efforts have been made to reduce the disadvantages by providing a panel assembly as is disclosed in Austrian Patent Specification No. 267825.
  • a panel assembly produced in accordance with this Austrian patent provides one panel having a series of support members with the support members of one panel having bosses with axially extending projections of lesser diameter than the bosses projecting from the free end of the bosses, and the bosses of the second panel having recesses complimentary with the dimensions of said axial projections of the bosses of the earlier mentioned panel, so that the projections engage the recesses to prevent lateral movement between the panels.
  • the individual panels of a pair of mating panels of the type in Australian Patent No. 2677825 are different, making the manufacturing costs high and effecting the interchangeability of the panels should either be damaged in use.
  • the panel assembly of applicant's invention seeks to overcome these problems and does so by providing a panel assembly for a floor, wall or ceiling comprising two spaced panels a plurality of support members extending outwardly from one side of each panel, an obverse side of each panel to that side having the support members having a substantially flat planar surface and the two spaced panels being arranged to overlie one another with the distal ends of the support member of one panel in abutting relationship with the distal ends of respective support members of the other panel, and locking means located at the front part of the distal ends, the locking means being arranged to prevent lateral movement of one panel relative to the other panel, and to lock the panels in a direction transverse to the plane of the panels, characterised in that the panels are identical and some abutting pairs of support members have a bore in each support member, which bores are alignable coaxially, the locking means located in the bores comprising locking pins mounted in the bore in each support member of each selected pair of abutting support members and some are provided with a
  • the panel assembly will be used as a flooring, although it will-be realised that it may, with advantage, be used as a double skin as well for constructing a wall or ceiling.
  • each panel is arranged on a regular matrix.
  • each locking pin preferably comprises a shank having a screw head at one end and a cross-pin at the opposite end therefrom, each bore being shaped to allow passage of the cross-pin therethrough.
  • Ribs may be located on the obverse side of each panel for interlocking the support for strengthening the panel. Conveniently, the ribs interlink the bosses. The height of each rib is 25% of the height of each boss.
  • each support member is a boss and the locking means engage abutting pairs of bosses located at each corner of the panels, which panels may be of glass reinforced plastics material.
  • each panel is rectangular which includes square, with the length of each side being 900 mm, the thickness of each panel being 3.5 mm, the bosses being spaced by 108 mm and each boss having a height of 46.5 mm tapering from its base of 17 mm diameter to 10 mm diameter at the distal end thereof.
  • a seal can be provided around the outer peripheral edge of each panel.
  • the present invention is preferably applied to a floor or wall or ceiling comprising a plurality of panel assemblies each having the features referred to above.
  • the present invention also provides a method of installing a panel assembly as referred to above for use as a flooring, a wall or ceiling, the method being characterised by laying a single layer concrete base with a substantially level surface as a substrate surface, laying over the concrete base an adhesive bedding compound and mounting the panel assembly on the bedding compound.
  • each panel 1, 2 each having an outer planar surface 3, 4 and opposed planar surfaces 5 and 6 from which project a plurality of bosses 7 and 8 arranged in a regular matrix configuration.
  • the panels 1, abut each other at corresponding contacting distal surfaces 9, 10 of the bosses 7, 8.
  • the panels 1, 2 have along each edge a flange 11 extending substantially perpendicularly to the panels in the direction of the bosses on each respective panel.
  • the flanges may slant outwardly by approximately 1° because of the moulding process.
  • One edge of each panel is provided with a cut-out (not shown) for lifting the panel in use.
  • the bosses 7, 8 are each of a frusto conical configuration extending from the opposed planar surfaces 5, 6.
  • a plastics ferrule 18 having an internal diameter substantially equal to the external diameter of the bosses at their junction with ribs 20 as hereinafter described, and a length equal to the combined length of the two bosses 7, 8 between the ribs.
  • the ferrules 18 prevent lateral movement between the two panels 1, 2. Referring to Figure 2, there is illustrated only nine bosses, although each panel 1, 2 has 81 bosses arranged on a 9 bossx9 boss matrix. Only four to six of these bosses have ferrules 18 to prevent the lateral movement between the panels.
  • the ferrules can be located at the corner bosses or at any other selected combination of bosses.
  • the mains services such as electrical wiring and telephone may be located as well as cables for computers in the spaces between the bosses 7, 8.
  • Each panel is also provided with ribs 20 for strengthening the panels.
  • the ribs interlink the bosses, and have a height which approximates to 25% of the height of each boss.
  • the single layer concrete base 25, as shown in Figure 1 is laid with its surface being substantially level.
  • the base is allowed to dry, whereupon an adhesive bedding compound 26 of 3 to 5 mm thick is laid over the surface of the concrete base.
  • the panel assembly comprising panels 1, 2 is laid on the bedding compound with the surface 4 of panel 2 in contact with the bedding compound and its bosses 8 projecting upwardly.
  • the whole flooring is laid in this manner.
  • various service engineers wish to lay cables, for example, they determine the locations between which the cables are to extend, lift the top panels 1 lying between these points and lay the cables in a substantially straight line or along any other path as desired.
  • the panels 1 are replaced and locked onto the panels 2.
  • Each panel 1, 2 is a one piece moulding of glass reinforced plastics material.
  • the moulding takes place at high temperature 140 to 150°C and at a pressure of 500 to 1000 psi (35.15 to 70.35 kg/ sq.cm) for 3 minutes.
  • the planar side 3, 4 of the panels cool more rapidly than the opposite side from which the bosses project because of the thick mass of material forming the bosses. Accordingly, the panels may be slightly concave on their planar side 3, 4. Consequently, two panels are placed together as described, not all opposed contacting surfaces 9,10 of the bosses contact each other.
  • a number of the bosses namely, the central bosses along each side of the 9x9 matrix, the boss in each corner, and each alternate boss along the diagonal between opposed corners, are provided with a central bore with diametrically oppositely extending grooves running the whole length of the bore.
  • the bore receives a plastics locking pin 12 which has an elongate shank having a screw head at one end and a cross-pin at the opposite end.
  • the grooves are shaped to allow passage of the cross-pin therethrough so that when the locking pin is passed through the bore it is rotated to move the cross-pin out of alignment with the grooves and lock the two panels together.
  • the locking pin has a spring beneath the screw head for holding the locking pin in position.
  • the panel surface 3, 4 is provided with a recess at the bosses having the bores so that the locking pins do not project beyond these surfaces.
  • top panel 1 can be quickly removed by releasing the locking pins.
  • Each panel is symmetrically formed and therefore the removed panel can be replaced on the bottom panel 2 with correctly interengaging bosses even though the panel may have been rotated through 90° prior to replacement.
  • the panels can be cut easily anywhere either for insertion of an electrical socket or alternatively to fill in a gap between the last laid panel and a wall. Where the cut occurs between adjacent bosses an elongate support, of wood for example, can be inserted between the panels parallel to the cut edges.
  • the panels are designed to withstand pressures between the bosses of 200 kg/25 mm 2 but nevertheless should ideally be supported as indicated above when cut.
  • Small bridges may be provided within the spaces between bosses so that telephone wires, electric cables and water pipes are separated from each other as necessary when they are run together, although such bridges are not usually required where these elements simply cross over each other.
  • the flooring proposed in accordance with the present invention it is possible to achieve a 50% reduction in wiring costs of a building including a substantial saving in costs since traditional wet screeding has been avoided.
  • a reduction in labour costs is obtained and furthermore no trunking is required within the sand and cement screed, although some trunking laid within the panelled flooring may be provided for special wiring if necessary.
  • the principal advantage with this trunking is that it need not be located specifically in tram lines at say 1.8 m spacing as in previous floor systems.
  • each panel When the flooring is laid it may be covered by carpeting or alternatively each panel may be provided with floor tiles or carpet tiles bonded to the panel surface 3.
  • the flooring structure described above is made of glass reinforced plastics material such as SY19/ 25/L sheet moulding compound by BTR Permali RP Limited, which when moulded produces a low profile surface.
  • the glass content is normally 25% glass reinforcement.
  • the flame spread is below class 2.
  • Each panel preferably has sides of 900 mm, is 3.5 mm thick and the bosses spaced by 108 mm have a height of approximately 46.5 mm. Each boss is 17 mm in diameter at its base and tapers to 10 mm diameter. Panels of this size are intended for use in buildings to be used as offices or for light industrial use. The panels can be utilized for heavy industrial applications, but for this use are generally thicker and bigger than those just described.
  • the flooring structure may be provided with grills for use as ducting to extrakt air.
  • the panel assembly could also be used for ducting in an air conditioning system, but it would then be necessary to adequately seal the joints between each panel assembly.
  • the ferrules may be omitted from the assembly described so that the locking pins are effective to both remove the dishing effect from the panels and prevent lateral movement between the panel pairs.
  • boss 8 is shown to have a central bore 30 with an enlarged diameter portion 31 in the region of the planar surface 4 for receiving the head of a locking pin (not shown).
  • the bore 30 has a restricted portion 32 defined by two spaced substantially semi-circular portions 33 of which only one is shown in Figure 3. Each portion 33 is provided with a cam surface 34 having a recessed portion 35 for receiving a locking pin.
