Definitions

  • This invention relates to building components and more particularly to flooring components adapted to attenuate the transmission of noise.
  • the concrete floors of multi-storey buildings are usually covered with materials such as carpet, floor tiles or timber floor boards.
  • JP11336300 describes securing floor joists on sleepers via a cushion material consisting of rigid rubber.
  • WO9514137 describes a composite having a support member, a fixing member and a noise attenuating member therebetween.
  • a polymeric noise attenuating member as defined in claim 1, and a floor as defined in claim 6.
  • Preferred embodiments are defined in the depentent claims.
  • the noise attenuating member is a body through which regularly space through openings are provided.
  • the noise attenuating member comprises a body in which there is formed a channel.
  • the composite building component 10 shown in Fig. 1 is constructed around a floor supporting timber batten and comprises a support member or joist 11, a noise attenuating member 12 and a fixing member or batten 13 to which a floor board or sheet 14 is secured by means of fastener 15.
  • the joist 11 is wood as is the batten or fixing member 13 and the noise attenuating member 12 is an extruded polymer blend of polyisoprene, natural rubber and butyl rubber having appropriate safety, toxicity and flammability properties and a density of 0.925 gm/cc. It is preferably a closed cell foam. Other noise attenuating materials may also be used.
  • the joist 11 is rectangular in cross-section and has planar sides 16, 17, a planar top face 19 and a planar bottom 18.
  • the noise attenuating member 12 has a planar bottom face 20 which sits upon the top face 19 of the joist portion 11.
  • a layer of adhesive may be placed between the top face 19 of the joist and the bottom face 20 so as to bond the noise attenuating member 12 to the batten portion 11.
  • the noise attenuating member 12 is of generally rectangular cross-section having a width which, in this instance, is the same as that of the joist portion 11.
  • the noise attenuator 12 has a body portion 21 and upwardly extending side walls 22, 23 which define therebetween a channel 24.
  • Optional inwardly directed top flanges 25, 26 of the respective side walls 22, 23 define a restricted entry 27 to the channel 24.
  • a fastening member 28 may be used to secure the member 12 to the support member 11. It will be noted that the head 29 of the fastener 28 is beneath the upper face 30 of the body portion 21 - that is, the head 29 is clear of the channel 24.
  • the batten or fixing member 13 is inverted "T" shape and has a body portion 31 and an upwardly facing fixing portion 32.
  • the body portion 31 is a neat fit in the channel 24 and the fixing member 13 is held in place by the flanges 25, 26.
  • the fixing member 13 could be of "I" cross-section with the flanges 25, 26 located in grooves along the side faces of the "I”.
  • the fastener 15 does not engage the noise attenuating member 12 and there is no direct connection between the fixing member 13 and the support 11.
  • the noise attenuating member 100 has a number of noise attenuating openings 101 therethrough.
  • the through openings 101 are evenly spaced along the longitude centre line 102 and pass completely through the body portion 21.
  • Each opening 101 is approximately 20mm in diameter.
  • the openings are spaced apart from one another by about 40mm (centre to centre).
  • the openings 101 reduce the surface area of the member 100 in contact with the fixing member 13 and the joist 11 and reduce the mass of the noise attenuating member 100 and therefore increase its effectiveness.
  • This modification to the embodiment depicted in Figure 1 causes a reduction in noise which is reflected in an Impact Insulation Class from 40 I.I.C. up to 64 I.I.C.
  • a timber batten of the type depicted in Fig. 1 may be provided with regularly spaced through holes 40. These through holes 40 may be used to insert fasteners 41 into an underlying supporting structure such as a timber joist or concrete slab. Note that the head 42 of the fastener 41 is smaller in diameter than the diameter of the through hole 40 and larger in diameter than the opening 43 which is provided in the body portion 21 of the noise attenuator 12. The openings 43 are provided between and in addition to the noise attenuating openings 101 which are depicted in Fig. 2 .
  • a typical timber batten 13 may have a top surface width 44 of about 34mm and a bottom surface width 45 of about 40mm.
  • the width 46 of the noise attenuator 12 is about 50mm and its overall height 47 is about 32mm.
  • the thickness of the side wall 48 is about 5mm and the depth of the flange 49 is about 3mm.
  • air borne noise may be attenuated by providing an adhesive polymeric tape or strip 60 between the timber batten 13 and the flooring that it supports. Tapes or strips of this type are generally 5mm thickness or less and need not necessarily span the entire width of the batten 13.
  • the batten and noise attenuator 12 of the present invention may be used in conjunction with a concrete slab 50 or in conjunction with timber joist 51.
  • Either type of substrate (50, 51) may be used in conjunction with optional suspended ceiling assemblies 52.
  • the composite batten of the invention has the added advantage of being able to be easily glued to the concrete slab, helping to prevent buckling as the moisture content of the timber flooring changes.
  • the composite batten of the invention would also provide better reduction of footstep noise common in multi-storey buildings with all timber flooring.
  • the composite building component of the invention will provide a cushioning effect.
