Definitions

  • This invention relates to a flooring structure, to structural components utilised in that flooring structure and to methods of forming such a flooring structure.
  • the concrete beams are heavy and difficult to handle. They are generally of pre-stressed construction, can be broken if handled incorrectly and do not lend themselves to spanning over intermediate supports.
  • the weight of the beams (and, if present, of the concrete blocks which they support) means that a substantial proportion of the structural capacity of the beams is required to support the dead weight of the floor itself.
  • a flooring structure comprises beams of box or inverted channel section, thermally insulating material supported between adjacent beams, and decking supported by said beams.
  • the flooring structure according to the invention is advantageous primarily in that the beams are relatively light in weight. They are therefore relatively easily handled, without the use of mechanical lifting gear, and their use is therefore accompanied by a lower risk of injury to those handling them.
  • the beams are also readily cut to any desired length and can be joined to form extended beams. They can also be placed over a series of supports without detriment to the beams.
  • a beam for use in a flooring structure said beam being of box or inverted channel section.
  • the beams are of inverted channel section, and are preferably formed from sheet material, eg by cold-forming.
  • the sheet material is most conveniently a metal sheet, eg of steel.
  • the beams are preferably protected against corrosion.
  • the beams may be galvanised or may have suitable paint or plastics coatings.
  • the sheet may be galvanised prior to forming, with any exposed edges being treated subsequently.
  • the beams are preferably formed with flanges or the like which extend transverse to the longitudinal axis of the beams. Such flanges serve to support thermally insulating material between pairs of beams.
  • the insulating material typically comprises rigid or semi-rigid boards, eg of expanded polystyrene. At least some of the insulating material is in the form of components of sufficient compressive strength to resist movement towards each other of the beams between which the insulating material is supported.
  • the insulating material should be of sufficient depth to provide the completed flooring structure with the desired degree of thermal insulation. Most preferably, the insulation material has a depth substantially equal to the depth of the beams, but the depth of insulation material may alternatively be less than this, or greater.
  • the interior of the beams is preferably filled with thermally insulating material, eg of expanded polystyrene.
  • the beams will be supported at 600mm centres or less and will lie parallel to each other.
  • the ends of the beams are preferably supported by the walls of the building, eg by being received within the inner leaf of a cavity wall or supported on suitable fixtures attached to the wall.
  • the decking supported by the beams may have any conventional form.
  • the decking may comprise tongued and grooved floorboards, particle board or plywood.
  • the decking may be insulated, eg by being bonded to a thermally insulating material to form a laminate.
  • the beams are preferably of inverted channel section and may have a variety of forms.
  • the beam may, for example, have a flat upper surface or the upper surface may be formed with an apex. In the latter case the weight of the decking may cause the upper surface of the beam to have a keying engagement with the underside of the decking, especially where the decking includes relatively soft thermal insulation material.
  • a flooring structure comprises a plurality of identical beams 1 arranged parallel to one another at 60cm centres and supported at their ends in the inner leaf of a blockwork cavity wall 2.
  • the ends of the beams 1 may be received within suitably formed recesses in the wall 2, or may be supported by suitable brackets fixed to the wall 2.
  • the beams 1 are formed by pressing galvanised steel sheet to form an inverted channel with lateral flanges 1a.
  • the inverted channel is filled with a thermally insulating material 3, such as polystyrene foam.
  • Blocks 4 of thermally insulating material are positioned between successive beams 1, being supported on the flanges 1a.
  • the flooring is completed by floorboards 5, eg tongued-and-grooved boards, laid on and supported by the beams 1.
  • Figure 2 shows several different profiles of beam which may be used in place of that shown in Figure 1.
  • the upper surface of the beam may be formed with an apex ( Figures 2a and 2b) or with a depression ( Figure 2c).
  • the top may alternatively be rounded ( Figure 2d) or have bevelled edges (Figure 2e).
  • Figure 3(a) shows a modified form 10 of a beam which is generally similar to the beam 1 shown in Figure 1.
  • the beam 10 differs from that described above in that steel reinforcements 11 of U-section are fitted sideways, internally of the inverted channel. Only one such reinforcement 11 is shown in the drawing, but in practice reinforcements would be fitted at intervals along the length of the beam 10.
  • Figure 3(b) shows an alternative construction of a beam 10a, again with a U-shaped reinforcement 11a. In this embodiment the reinforcement 11a is inverted.
  • an inverted U-shaped reinforcement 11b extends along substantially the whole length of the beam 10b and extends below the soffit of the unit. The overall depth of the structure, its stiffness and spanning capability are thereby enhanced.
  • the reinforcement 11b is stopped short of the end of the beam 10b with the result that these attributes are substantially retained whilst allowing the beam 10b to bear on a supporting structure 15.
  • a soffit plate 21 is fitted to the underside of the flanges 20a.
  • the soffit plate 21 may extend along the full length of the beam 20 or a number of soffit plates 21 may be fitted at intervals along the beam 20.
  • the beam 30 shown in Figure 5(a) differs from those previously described in that it is formed from two symmetrical wall components 31,32 which are held together by U-section spacers 33 positioned sideways between them.
  • Each wall component 31,32 may be formed by pressing relatively narrow lengths of steel sheet. Such a construction may therefore utilise scrap lengths of sheet material.
  • the wall components 31a,32a are held together by spacers 33a of inverted U-section.
  • Figure 5(c) shows a modification similar to that of Figure 3(c), in which the spacer 33b extends below the lower surfaces of the wall components 31b,32b.
  • Figure 6 shows how the space between beams 60 may be filled with insulating material 61 of depth equal to the depth of the beam 60 (as also shown in Figure 1), or with material 62 of greater thickness or material 63 of lesser thickness.
  • the beam may be filled with insulating material similar to that incorporated into the beam 1 of Figure 1.
