Description
- This invention relates to building components and more particularly to flooring components adapted to attenuate the transmission of noise.
- For the sake of convenience, the invention will be described in relation to floor joists, but it is to be understood that the invention is not limited thereto as the building component of the invention may be used in a variety of situations where noise attenuation and/or resiliency is required or desired.
- The concrete floors of multi-storey buildings are usually covered with materials such as carpet, floor tiles or timber floor boards.
- One of the problems associated with multi-story buildings utilizing wooden flooring is that the direct nailing of floor boards or sheets to the floor joists provides a composite solid medium for the transmission of noise from the floor boards and floor joists through the concrete floor to the roam below.
-
JP11336300 -
WO9514137 - It is, therefore, an object of the present invention to provide a composite building component which inherently attenuates sound transmission.
- According to the invention this object is achieved by 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.
-
-
Fig. 1 is a top plan view of a composite building component according to an embodiment not covered by the claims. -
Fig. 2 depicts an embodiment of the invention in top plan view. -
Fig. 3 is a schematic cross-section of a timber batten and noise attenuating member. -
Fig. 4 is a perspective view, partially cross-sectioned, of the invention as applied to a concrete slab. -
Fig. 5 is a perspective view, partially cross-sectioned, of the invention as applied to a timber joist supported floor. - The
composite building component 10 shown inFig. 1 is constructed around a floor supporting timber batten and comprises a support member orjoist 11, anoise attenuating member 12 and a fixing member or batten 13 to which a floor board orsheet 14 is secured by means of fastener 15. - In this example, the
joist 11 is wood as is the batten orfixing member 13 and thenoise 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 hasplanar sides top face 19 and aplanar bottom 18. Thenoise attenuating member 12 has aplanar bottom face 20 which sits upon thetop face 19 of thejoist portion 11. A layer of adhesive may be placed between thetop face 19 of the joist and thebottom face 20 so as to bond thenoise attenuating member 12 to thebatten 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 thejoist portion 11. Thenoise attenuator 12 has abody portion 21 and upwardly extendingside walls channel 24. Optional inwardly directedtop flanges respective side walls entry 27 to thechannel 24. A fasteningmember 28 may be used to secure themember 12 to thesupport member 11. It will be noted that thehead 29 of thefastener 28 is beneath theupper face 30 of the body portion 21 - that is, thehead 29 is clear of thechannel 24. - In this instance, the batten or
fixing member 13 is inverted "T" shape and has a body portion 31 and an upwardly facingfixing portion 32. The body portion 31 is a neat fit in thechannel 24 and thefixing member 13 is held in place by theflanges fixing member 13 could be of "I" cross-section with theflanges noise attenuating member 12 and there is no direct connection between thefixing member 13 and thesupport 11. - As shown in
Figure 2 , in the invention, thenoise attenuating member 100 has a number ofnoise attenuating openings 101 therethrough. In this example, thethrough openings 101 are evenly spaced along thelongitude centre line 102 and pass completely through thebody portion 21. Eachopening 101 is approximately 20mm in diameter. The openings are spaced apart from one another by about 40mm (centre to centre). Theopenings 101 reduce the surface area of themember 100 in contact with thefixing member 13 and thejoist 11 and reduce the mass of thenoise attenuating member 100 and therefore increase its effectiveness. This modification to the embodiment depicted inFigure 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. - As shown in
Fig. 3 , a timber batten of the type depicted inFig. 1 may be provided with regularly spaced throughholes 40. These throughholes 40 may be used to insertfasteners 41 into an underlying supporting structure such as a timber joist or concrete slab. Note that thehead 42 of thefastener 41 is smaller in diameter than the diameter of the throughhole 40 and larger in diameter than theopening 43 which is provided in thebody portion 21 of thenoise attenuator 12. Theopenings 43 are provided between and in addition to thenoise attenuating openings 101 which are depicted inFig. 2 . - With reference to
Fig. 3 , it can be seen that atypical timber batten 13 may have atop surface width 44 of about 34mm and abottom surface width 45 of about 40mm. Thewidth 46 of thenoise attenuator 12 is about 50mm and itsoverall height 47 is about 32mm. The thickness of theside wall 48 is about 5mm and the depth of theflange 49 is about 3mm. Also note that air borne noise may be attenuated by providing an adhesive polymeric tape orstrip 60 between thetimber 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 thebatten 13. - As shown in
Figs. 4 and 5 , the batten andnoise attenuator 12 of the present invention may be used in conjunction with aconcrete slab 50 or in conjunction withtimber joist 51. Either type of substrate (50, 51) may be used in conjunction with optional suspendedceiling 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.
- Apart from the noise attenuating aspect of the floor batten, the composite building component of the invention will provide a cushioning effect.
- Floors constructed according to the present invention have been tested by Australia's CSIRO (Commonwealth Scientific and Industrial Research Organisation). A complete report on the impact sound insulation qualities of the present invention are contained in a publicly available CSIRO report (Measurement No. TIi401). The results of that report indicate that the teachings of the present invention provide a fixed flooring system achieving an I.I.C. rating of about 50 which rating is obtained with a timber only flooring with no carpet, underlay, tile, vinyl flooring or other covering. I.I.C. refers to the Impact Insulation Class, a single number index of performance which can be used for comparing floor/ceiling assemblies for general building design purposes. The index is calculated from measured values of the (normalised) third-octave impact sound pressure levels. The procedure for calculating I.I.C. number is specified by the American Standard ASTME989-89. As such, fixed flooring systems made in accordance with the teachings of the present invention are about to be the only ones in the world to have achieved a rating of above I.I.C. 50.
- Various modifications may be made in the shape, configuration and composition of the members which comprise the composite building component without departing from the scope and ambit of the invention, as described by the appended claims.
