Definitions

  • the present invention relates to a wall stud having improved acoustic and mechanical properties.
  • a common building technique for the fabrication of building walls, and in particular internal walls, is to fasten sheets of walling material, such as plasterboard, to vertical channel section beams known as wall studs.
  • US-A-6,381,916 discloses such a wall stud.
  • each stud is secured to a horizontal beam or channel secured to either the floor or ceiling of the room in which the interior wall is being constructed.
  • This wall construction technique is both relatively simple and inexpensive and further allows existing room spaces to be subdivided if required, for example when altering the use of an existing building.
  • this kind of 'double stud' construction usually requires some form of brace to be fastened between parallel studs spanning the air gap to give the structure adequate strength.
  • the brace provides a necessarily stiff connection between studs, it also provides a bridging sound transmission point, reducing the sound insulating performance of the wall.
  • the substantially semicircular member has a plurality of rows of elongate slots formed therein, adjacent rows being longitudinally offset from one another.
  • the slots are preferably at least twice the length of the interconnecting portions of the substantially semicircular member.
  • the diameter of the substantially semicircular member is approximately equal to the width of each of the first and second planar members.
  • At least one of the sidewalls may have a longitudinal acute groove, for example, a V-shaped groove, extending over at least a portion of the length of the stud. Additionally, the acute groove is located substantially midway across the width of the sidewall.
  • At least one of the surfaces of the sidewalls facing away from each other has a plurality of depressions formed therein.
  • the depressions may be pyramidal in shape.
  • the depressions may be formed by a deep knurling process and/or a corrugating process. The depressions increases the stiffness of the sidewalls, thus making it easier to fasten wall boards to the stud.
  • a first non-woven tissue may extend across opposing edges of the curved member, whereby an enclosed space is defined between the non-woven tissue and the curved member, and a second non-woven tissue may extend between the opposing sidewalls.
  • a sheet of material having sound insulating properties may extend between the opposing sidewalls.
  • the sheet of material may comprise glass or rock mineral wool matting, spun bonded polyester wool foamed plastics, or any other suitable sound absorbing material.
  • Figure 1 illustrates in plan view a first embodiment of the present invention.
  • the stud 2 has first and second sidewalls 4, 6 to which, in use, sheet walling material, indicated by chained lines 8, 10 can be attached.
  • the sidewalls 4, 6 are substantially parallel to one another and/or substantially equal in width, their length being equal to the length of a wall stud and therefore equivalent to the height of the wall being constructed.
  • Interconnecting the sidewalls 4, 6 along respective edges is a spanning web 12 that comprises first and second planar portions 14, 16 projecting from the respective sidewalls 4, 6 and a curved member 18 interconnecting the first and second planar portions.
  • the curved member is semicircular, such that should two identical wall studs be brought together with their spanning webs 12 adjacent to one another, the respective curved members 18 will form a complete circle. Additionally, in-turned flanges 20, 22 extend inwards from the free edges of the sidewalls 4, 6 and are substantially parallel to the portions 14, 16.
  • Figure 2 shows a front perspective view of the stud shown in Figure 1 and it can be seen that the curved member 18 has a number of longitudinal slots 24 formed along its length and, in the embodiment shown, along the central axis of the curved member 18.
  • the length of the longitudinal slots 24 is at least twice that of the interconnecting portions of the curved member 18.
  • the curved member 18 introduces sufficient resilience to the wall stud to allow some flexing of the stud, which absorbs some of the vibrational energy imparted to the wall stud 2 by soundwaves incident on the sheet wall members 8, 10.
  • the longitudinal slots 24 further improve the sound insulating qualities of the stud 2 by providing a physical break in the transmission path of the sound vibrations through the curved member 18.
  • the slots 24 also minimise the material used in spanning web 12.
  • each depression is preferably 2mm square and 2mm in-depth and are formed in a repeating pattern 2mm apart from one another. The depressions increase the stiffness of the sidewalls making it easier to attach sheets of wall material to them, for example using screws. Also more clearly visible in Figure 2 are acutely angled grooves 28, 30 formed within the respective sidewalls 4, 6 and directed towards each other.
  • Preferred dimensions for the wall stud 2 are as follows:
  • the spanning web 12 may be between 40mm and 150mm in width.
  • the width of the curved member 18, or diameter may be approximately 1 ⁇ 3 of the total width of the spanning web 12, with the curved member 18 located substantially centrally in the web.
  • the width of the sidewalls 4, 6 may be between 32mm and 52mm.
  • the width of the interned flanges 20, 22 may be between 6mm and 12mm.
  • the length of the slots 24 may be approximately 70mm.
  • the separation of the slots 24 may be between 10mm and 25mm (i.e. the length to separation ratio of the slots is approximately 3:1).
  • the width of the slots 24 is approximately between 1mm to 4mm.
  • Figure 3 illustrates a further embodiment of the present invention in which more than a single row of elongate slots are provided along the length of the curved member 18.
  • a first and second row of slots 24, 25 is provided, with the second row of slots 25 being displaced along the length of the curved member 18 by approximately half the length of a slot with respect to the first row of slots 24.
  • the two rows of slots are equally spaced apart across the curved member 18.
  • Figure 4 illustrates a further embodiment having a first, second and third row of elongate slots 24, 25, 27 provided along the length of the curved member 18, with the third, middle, row of slots 27 being displaced relative to the first and second rows 24, 25.
  • further rows of slots may be provided, preferably equally spaced around the curved member 18.
  • FIG. 5 A further embodiment of a wall stud according to an embodiment of the present invention is shown in Figure 5.
  • the stud includes first and second planar portions 14, 16 interconnected by a curved member.
  • a row of diagonal slots 24' is provided in the curved member. The slots extending across a substantial proportion of the circumference of the curved member but not across its entirety.
  • Figure 6 illustrates a plan view a further embodiment of wall stud according to the present invention.
  • the stud 2 has a non-woven fibreglass tissue 32 extending across the open face of the curved member 18 and attached to a first and second portions 14, 16 of the spanning web 12.
  • a second non-woven tissue 34 extends between opposing surfaces of the sidewalls 4, 6. The provision of the non-woven fibreglass tissue increases the sound absorbing performance of the wall stud 2.
  • Figure 7 shows an alternative embodiment of wall stud according to the present invention in which a sheet of sound absorbing material 36 extends between opposing faces of the sidewalls 4, 6, substantially filling the space defined by the sidewalls and spanning web 12 of the stud 2.
  • the sound absorbing material 36 may be fibreglass insulation, spun bonded polyester wool, or any other suitable material.
  • the embodiment shown in Figure 4 provides an improved sound insulation performance for the stud 2. Both of the embodiments shown in Figures 3 and 4 reduce the sound transmission across the stud by approximately 2dB.
  • a stud wall construction according to prior art techniques is schematically illustrated in Figure 8.
  • Two parallel vertical studs 81 and 82 are provided, to each of which a single sheet of plasterboard or other walling 83 is fastened.
  • Each row of studs is located in an upper and lower horizontal track.
  • a brace 84 is fastened between the studs 81, 82.
  • the brace 84 has a resilient section 85 formed by folded sections of the brace in an effort to reduce its sound transmission qualities.
  • the stud wall construction illustrated in Figure 9 using a stud 2 in accordance with embodiments of the present invention.
  • the stud 2 used is substantially larger than the prior art studs 81, 82 shown in Figure 8 and is located in appropriately sized single upper and lower tracks. This allows sheets of plasterboard 83 to be fastened to the outer face of the opposing sidewalls of the stud 2, whilst still providing an air gap between the plasterboard sheets that is substantially the same as that provided by the prior art stud wall construction illustrated in Figure 8.
  • the curved member 18 of the stud 2 provides similar resilience as that provided by the resilient portion 85 of the prior art brace 84.
