Abstract
A noise attenuating member (12) has a channel (24) for receiving a timber batten (13). A flooring (14) may be affixed to the batten (13). The noise attenuating member acts as a cushion between the batten (13) and a substrate such as a joist (11, 51) or a concrete slab (50). Noise attenuating holes (1201) and retaining flanges (25, 56) may optionally be provided.
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 utilising 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 room below.
- It is, therefore, an object of the present invention to provide a composite building component which inherently attenuates sound transmission.
- According to the invention there is provided a composite building component comprising a fixing member and a noise attenuating member. The noise attenuating member is preferably a body through which regularly space through openings are provided.
- In one embodiment of the invention, the noise attenuating member comprises a body in which there is formed a channel,
- In another embodiment, the channel is defined by a pair of opposed side walls which terminate in inwardly directed top flanges.
- In another embodiment, there is provided a combination of a fixing member and a noise attenuating member in which the fixing member is retained by the flanges of the noise attenuating member.
- FIG. 1 is a top plan view of a composite building component according to a second embodiment of the invention.
- FIG. 2 depicts an alternate 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 in FIG. 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 offastener 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 optional upwardly extendingside walls 22, 23 which define therebetween achannel 24. Optional inwardly directedtop flanges respective side walls 22, 23 define a restrictedentry 27 to thechannel 24. A fasteningmember 28 may be used to secure themember 12 to thesupport member 11. It will be noted that the head 29 of thefastener 28 is beneath theupper face 30 of thebody portion 21—that is, the head 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 fastener 15 does not engage thenoise attenuating member 12 and that there is no direct connection between thefixing member 13 and thesupport 11. - As shown in FIG. 2, the
noise attenuating member 100 may be provided as a module of indeterminate length (or in sections) in which a number of throughopenings 101 have been provided. In this example, thethrough openings 101 are provided along thelongitude centre line 102 and are evenly spaced. In one example, thethrough openings 101 pass completely through thebody portion 21. Eachopening 101 is approximately 20 mm in diameter. The openings are spaced apart from one another by about 40 mm (centre to centre). Theopenings 101 reduce the mask of thenoise attenuating member 100 and therefore increase its effectiveness. This modification to the embodiment depicted in FIG. 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 in FIG. 1 may be provided with regularly spaced through holes40. 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 thehead 42 of thefastener 41 is smaller in diameter than the diameter of the through hole 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 in FIG. 2. - With reference to FIG. 3, it can be seen that a
typical timber batten 13 may have atop surface width 44 of about 34 mm and abottom surface width 45 of about 40 mm. Thewidth 46 of thenoise attenuator 12 is about 50 mm and itsoverall height 47 is about 32 mm. The thickness of theside wall 48 is about 5 mm and the depth of theflange 49 is about 3 mm. 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 5 mm thickness or less and need not necessarily span the entire width of thebatten 13. - As shown in FIGS. 4 and 5, the batten and
noise attenuator 12 of the present invention may be used in conjunction with a concrete 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.
