  • Fig. 1 shows a building foundation 10.
  • the foundation 10 is located at an external wall of a building.
  • a plurality of piles 12 are installed in the ground 14.
  • Elongate members 16 span between adjacent piles 12 and are supported by the piles 12.
  • a floor structure 18 is provided, and is supported, at least in part, by the elongate members 16.
  • the elongate members 16 are metal members, to be described more fully below.
  • the metal members 16 have a line of vent apertures 20 spaced along their length to provide venting through the elongate member to the underside of the floor structure 18.
  • the elongate members 16 also form a composite support member, with the floor structure, as will be described.
  • the piles 12 may be driven into the ground 14, or formed in-situ in a preformed hole in the ground 14. They may be made of concrete or other cementitious material and may incorporate reinforcing members.
  • the piles are preferably enlarged at their upper ends to form pile caps 22.
  • the pile caps can be seen from the drawings to be much wider than the main body of the pile 12.
  • each pile cap 22 provides a surface on which the ends of the elongate members 16 may be rested for support.
  • the relatively large diameter of the pile caps allows the elongate members to be placed on the caps 22 at any of a range of positions, as will become apparent.
  • Ties (not shown) may be provided to tie the elongate members to the piles 12.
  • the elongate members 16 are shown in more detail in Figs. 2 and 3. Each is formed from metal, preferably steel, and preferably by a rolling process to provide a constant cross-section along the length of the elongate members.
  • the elongate member 16 has elongate structures 24 which extend transversely to form feet to rest on the caps 22.
  • a central section 26 is provided by side walls 28. Vent apertures 20 are formed at least in the side walls which faces the exterior of the building. Thus, ventilation air can pass through the apertures 20 from outside the elongate member 16 to within.
  • a relatively narrow trough 36 bounded by a wall 38 carrying a supporting flange 40.
  • a relatively wide supporting surface 42 is provided.
  • the flange 40 is used to support an insulating layer 44 of the floor structure.
  • the layer 44 may, for example, be a layer of polystyrene material.
  • the upper surface of the layer 44 is covered by a layer of settable material, preferably cementitious material such as concrete.
  • the concrete 46 is allowed to flow, prior to setting, past the edge of the layer 44 and down into the trough 36, thus filling the trough 36 and the gap between the edge of the layer 44 and the corresponding wall 28.
  • the wall 28 is adjacent a vertical wall of concrete 46 and the trough 36 is filled with concrete.
  • the concrete and the elongate member 16 thus together form a composite beam structure whose strength is determined not solely by either the metal or the concrete, but by the combination of both elements.
  • the concrete layer 46 preferably finishes at approximately the same level as the upper edge of the walls 28.
  • An internal block or brick skin 48 is supported by the concrete 46, close to the elongate member 16.
  • the supporting surface 42 is used to support the outer brick skin 50 of the wall.
  • bricks of the skin 50 are replaced with vent structures 54 which provide an open vent channel 56 through the outer skin to the vent apertures 20, covered at the external surface of the skin 50 by a mesh 58.
  • Ground level within the building is at the level 60, below the level 52.
  • a void 62 therefore exists below the layer 44 and above ground level 60.
  • a ventilation path 64 is provided, indicated by a broken arrow on Fig. 3.
  • the path 64 extends from outside the building, through the vent structure 54 into the wall cavity 66, through apertures 20 into the interior of the elongate member 16, under the trough 36 (except in the vicinity of a pile cap 22) to the void 62.
  • ventilation of the void 62, to the exterior of the building is provided.
  • a strip of skirt material 68 is preferably provided, running horizontally between adjacent pile caps 22 to close the aperture defined below the elongate member 16, above the inner ground level 60 and between the pile caps. This prevents the ingress of material from outside the building, into the void 62.
  • Fig. 4 shows an arrangement for forming a party wall in accordance with the invention.
  • Many components and features illustrated in Fig. 4 are the same or closely correspond with features and components of the arrangements previously described and are thus given the same reference numeral, or a reference numeral accompanied by an appropriate suffix.
  • a single line of piles 12 and pile caps 22 are used to support two parallel elongate members 16A.
  • Each elongate member 16A has substantially the same profile as that part of an elongate member 16 (Fig. 2) from the peak of the central section 26, and including the trough 36.
  • the troughs 36 face in opposite directions and can thus each support a corresponding floor structure of the type described above, including insulating layes 44 and concrete 46.
  • the edges of the two floor structures are supported by respective elongate members 16A but by the same line of piles 12.
  • Fig. 5 shows a further alternative arrangement. This arrangement is for supporting an internal load-bearing wall 74. Again, many features are the same as, or correspond with previously described features and are thus given the same reference numerals or corresponding reference numerals and a letter suffix.
  • a line of piles 12 and pile caps 22 support elongate members 16B in the form of a shallow trough 76 having side walls 78 carrying transversely extending flanges 80.
  • the profile of the walls 78 and flanges 80 corresponds with that of the features 40, 42 of the arrangement shown in Fig. 3, and are again used to support respective insulating layers 44. These are covered by concrete 46.
  • a gap 82 is left between the edges of the insulating layers 44, allowing the concrete 46, prior to setting, to flow down into the gap 82, thereby filling the trough 76.
  • a composite beam is formed by the combination of the trough 76 and the concrete within it. This composite beam spans between adjacent pile caps 22, to provide support for the floor structures. The composite beam also provides sufficient strength to allow the load-bearing wall 74 to be built along the line of the elongate member 16B.
  • a gap 86 exists above each pile cap 22, between the ends of the elongate members 16 supported by that cap 22.
  • This gap 86 can provide additional ventilation to the space 30.
  • a gap as large as that illustrated in Fig. 1 will, not be present in all arrangements, as can be seen by considering Fig. 4.
  • the ability of the pile caps 22 to support the end of an elongate member over a range of axial positions of the elongate member relative to the cap allows a single length to be used with a range of different pile separations or alternatively, a particular pile spacing could be used with a range of different lengths of elongate member.
  • elongate members would be provided in a range of stock sizes, perhaps ranging from 2m to 4m and with an increment of about 300mm between lengths.
  • the increment should be less than or equal to the range of support provided by the caps 22. Consequently, a particular length can be used for spanning between two piles at any range from a lower limit to an upper limit, the length of that range being determined by the size of the pile cap 22.
  • the pile spacing is increased so that the upper limit is exceeded, or is reduced so that the lower limit is not met, so the next longest or shortest standard length can be used. This results in a continuum of possible pile separations being available, by appropriate choice of standard lengths.
  • a first wall 90 is formed from three elongate members 16 supported by a line of four piles 12.
  • the inner two piles 12 also support elongate members extending transversely from the wall 90, such as might occur within the footprint of a building, for a dividing wall.
  • a second wall 92 is also defined by three elongate members 16 supported by piles 12. Again, the inner piles 12 support further elongate members extending transversely away from the wall 92.
  • the separation of piles 12 in the two walls 90, 92 is not the same.
  • each wall is made solely from elongate members of stock length, as described above. Thus, appropriate choices of length and pile position enable a wide range of foundation geometries to be created without any components being required to be bespoke in form.
  • Fig. 8 shows an example of a pile cap 22 supporting the ends of three elongate members 16.
  • the shape of each elongate member, in plan, is not square at its end but rather, the corners are cut at an angle. This ensures that gaps remain between ends for ventilation, even when three elongate members are supported by the same cap.
