Definitions
- the present invention relates to members used in construction, especially in applications where sound attenuation and sound isolation is important.
- the present invention relates to construction members used to construct building structures in which sound transmission from one room to another is to be prevented or reduced.
- the present invention also relates to a system and method for retrofitting a pre-existing standard wall with an improved stud construction which improves sound attenuation characteristics across the wall.
- Standard wall frame systems including a plurality of interconnected individual studs have long been used to construct walls. Also, in general, it is conventionally known to resiliently mount a wall or ceiling in order to isolate sound or attenuate transmission therethrough.
- U.S. Patent No. 3,445,975 to Nelsson discloses a partition in which first and second lath panels are held against a metallic stud, channel, or furring member by a clip fastener. One portion of the stud, channel, or furring member is cantilevered away from the portion at which the lath panels are clipped thereto. According to Nelsson, this permits the free portion of the stud, channel, or furring member to flex as the lath panels mechanically respond to sound waves incident thereon. The remainder of the structure dampens this surface movement, reducing sound transmission to the opposite surface of the partition.
- U.S. Patent No. 3,324,615 to Zinn discloses a construction member having a plurality of laterally extending supporting tabs by which wallboard segments are resiliently mounted.
- U.S. Patent No. 3,046,620 to Tvorik et al. discloses a ceiling hanger member whereby a furring strip (to which a ceiling member is attached) is resiliently attached to a joist, such that the weight of the furring strip and ceiling member resiliently separates the furring strip from the joist.
- Another known method of sound attenuation is to build a wall frame in which individual studs are laterally staggered relative to a toe plate and head plate. Therefore, alternate studs are used to mount wall board on respective sides of the frame so that a given stud is spaced away from one of wall boards.
- the foregoing conventional methods of noise attenuation are problematic in that they generally move away from basic construction methods and thereby increase complexity and cost.
- a standard wall frame system must generally be completely torn down to put a conventional sound attenuating systems into place. It would be therefore desirable to be able to retrofit a standard wall frame system so as to increase its sound attenuation characteristics.
- U.S. Patent No. 4,466,225 to Hovind discloses a structure for making preexisting studs in effect wider, so as to define deeper spaces for insulation therebetween. Hovind is directed to modification of studs in a frame, and not to a system by which a preexisting wall system is retrofitted. Hovind does not mention that the metal channels are resilient, especially for the purpose of sound attenuation.
- a wood I-beam is commercially available (for example, under the brand name "BCI Advantage” from Boise Cascade Corporation) that comprises a pair of wood members with a rigid wooden panel extending therebetween.
- BCI Advantage the brand name "BCI Advantage” from Boise Cascade Corporation
- this I-beam offers little or no sound attenuation benefit.
- the present invention is therefore most generally directed to a construction member that relies on resilient flexibility in order to attenuate sound transmission therethrough, but also more closely conforms to conventional building members in order to minimize or eliminate the need for any special handling or the like in use.
- a system for retrofitting a preexisting wall comprises a system of construction members (for example, without limitation, conventional 2"x4" (5.08 cm x 10.16 cm) wood beams) arranged in a manner corresponding to the studs underlying the preexisting wall.
- Each construction member includes one or more resilient members (for example, resilient webs, resilient channels) mounted thereon on one side thereof.
- each of the construction members is mounted (by way of the one or more resilient members) on the preexisting wall in a location corresponding to a stud underlying the preexisting wall.
- each resilient member is fastened to an underlying stud of the preexisting wall through the wall material (for example, drywall) in a conventional way (including, without limitation, bolts, screws, nails, staples).
- the new construction members are at least partially decoupled from the preexisting wall so as to reduce the sound transmission path therebetween.
- wall board including, without limitation, drywall and plywood
- wall board is mounted on the thusly arranged construction members thereby creating a new wall surface. It is particularly desirable to provide insulation between the thusly arranged construction members to enhance sound attenuation characteristics and, secondarily, to enhance thermal insulation characteristics.
- Each resilient member may beneficially be provided with one or more spacers thereon so that the corresponding construction member may be easily positioned relative thereto (that is, "jigged").

- Figure 17 illustrates a third variant of the resilient members used according to the fifth embodiment of the present invention.
- FIGS 1 and 2 illustrate a portion of a beam 100 according to the present invention.
- beam 100 comprises lateral members 102 and 104 with a web 106 spanning therebetween.
- Lateral members 102, 104 are generally rectangular or squared in cross- sectional profile and preferably have at least the same thickness y (see Figure 2).
- lateral beams 102, 104 are preferably identical so that each has the same width, proportionately spaced with web 106 therebetween so as to present an overall beam width x.
- Lateral members 102, 104 are preferably (but not necessarily) identical in shape so as to facilitate manufacture of beam 100 from one source of stock.
- beam 100 can present a cross section having a major dimension x and minor dimension y corresponding to any standard beam size (for example, 2" x 4" (5.08 cm x 10.16 cm), 2" x 6" (5.08 cm x 15.24 cm), and so on, without limitation).
- any standard beam size for example, 2" x 4" (5.08 cm x 10.16 cm), 2" x 6" (5.08 cm x 15.24 cm), and so on, without limitation).
- lateral members 102, 104 are elongate rigid members. Accordingly, a variety of suitably rigid materials could be used. However, lateral members 102, 104 are preferably (but not exclusively) made from wood, (in part, in keeping with an intent of the present invention to present a construction member very similar to those conventionally used in the art). Wood is also desirable because it can be worked, generally, in more ways than comparable metal members (for example, it can be easily cut, driven with nails or screws). Not only can continuous lumber be used, but composite materials, such as plywood or wood particle board can be used. In addition, fmger jointed wood members can be used according to the present invention. A plastic material reinforced with glass fibers may also be used in accordance with the present invention.
- Web 106 is made from a relatively rigid material that has some flexibility. If web 106 is relatively too flexible, lateral members 102, 104 have too much relative freedom of movement and beam 100 is no longer, overall, a rigid member. If web 106 is relatively too stiff, then the benefits of sound isolation/attenuation are lost. Generally, web 106 may be made from any suitably stiff and resilient material, including (without limitation) rubber, asphalt, plastic or other resilient polymeric material. In one example of the present invention, web 106 is made from galvanized 22 gauge steel. As seen in Figure 4, web 106 includes edge portions 106a and an intermediate portion 106b.
- Edge portions 106a are embedded in lateral members 102, 104, and intermediate portion 106b extends obliquely between lateral members 102, 104. However, intermediate portion 106b may. most generally, extend between lateral members 102, 104 in any orientation so long as flexure between lateral members 102, 104 is relatively easy (compared to, for example, an intermediate portion extending straight across the gap between lateral members 102, 104, which does not readily flex).
- galvanized steel as described here may offer additional ancillary benefits, such as improved fire safety protection.
- Edge portions 106a are embedded in lateral members 102, 104 in any conventional manner.
- One possible method is to form grooves in lateral members 102, 104 that are wider than the thickness of edge portions 106a. Once edge portions 106a are suitably disposed in the respective grooves, additional strips of material (such as wood) are pressed into the remaining space in the grooves, such that edge portions 106a are wedged into place and retained in the grooves.
- Web 106 may extend continuously substantially the entire length of lateral members 102, 104. However, when beams 100 are used in construction, it is useful to provide a plurality of spaced apart webs 106, such that piping, wiring and the like can be passed through the openings between webs 106 (see Figure 3).
- beams 100 are provided in standardized lengths (for example, 8') as seen in Figure 3 and can be cut down as required.
- Figure 5 is a partial perspective view of a frame work (as might be used for walls in a building).
- beams 100a, 100b are mounted as studs on a laterally extending beam (that is, a head plate or toe plate) 100c.
- a laterally extending beam that is, a head plate or toe plate
- another laterally extending beam (not shown) is provided at the other end of beams 100a, 100b.)
- the structure of each of beams lOOa-lOOc is in accordance with the description of the present invention hereinabove, and will not be repeated here.
- lateral members 102a and 102b and 104a and 104b are mounted with respect to lateral members 102c and 104c, respectively, with nails, screws or any other conventional fasteners (not shown here). Accordingly, it can be appreciated that one side of the frame (that is, lateral members 102a- 102c) are resiliently separated by way of respective webs 106', 106", and 106'" from the other side of the frame (that is, lateral members 104a-104c). Accordingly, sound impinging on a wall member mounted on one side of the frame is attenuated upon transmission to the other side of the frame because of the resilience of webs 106', 106", and 106'".
- a wall it is possible to resiliently mount a wall so that it acts like a diaphragmatic sound absorber.
- a wall which only one "side" of the frame assembly (for example, lateral member 104c and/or lateral members 104a, 104b) is fixed to the surrounding building structure, and the other side of the frame assembly has wall board or the like mounted thereon (that is, on lateral members 102a, 102b), without attachment to the surrounding structure.
- the wall is therefore mounted on the "free” or "floating" side of the studs.
- a soft gasket made from, for example, foam rubber
- Such insulation can be of any conventional type, including blown, rolled or batting, foam board The addition of such insulation enhances sound attenuation effects resulting from the present invention.
- Figures 6 and 7 are a partial perspective view and a partial plan view, respectively, of beam 200, in accordance with another embodiment of the present invention.
- the design concept underlying beam 200 is fundamentally similar to that of beam 100.
- lateral members 202 and 204 are provided, and are resiliently spaced apart from each other by web 206.
- web 206 is not embedded in lateral members 202, 204. Instead, web 206 is fixed (by any conventional means, such as nails 205, as shown in Figures 6 and 7) relative to opposite faces of lateral members 202, 204 along the major dimension of the beam cross section.
- a plurality of spaced apart webs 206 may be provided along the length of beam 200 (see, for example, Figure 7).
- Web 206 is preferably made from a material that is slightly more flexible than that used for web 106, such as 24 gauge galvanized steel.
- beam 300 comprises lateral beams 302 and 304, and includes a plurality of first webs 306a which are spaced from and alternate with a plurality of second webs 306b. Accordingly, respective intermediate portions of webs 306a and 306b criss-cross as seen from an end of beam 300.
- a beam according to the present invention can be specifically manufactured so that its resilient properties (in terms of, for example, spring constant) are made to correspond to a particular kind of sound (especially in terms of its frequency) so that sound attenuation can be maximized.
- Such "tuning” can be accomplished by varying the thickness of web 106, 206, either uniformly or variably over the entire area of web 106, 206.
- notches, slits, or other openings can be formed in web 106, 206 to control the resilience of web 106, 206 in accordance with known principles of physics.
- suitably sized perforations or openings in a continuous web can be formed so as to create a tunable Helmholtz resonator effect between adjacent cavities defined between studs in the framework illustrated in Figure 5. By altering the number and/or size of the perforations or openings, a resultant Helmholtz resonant frequency can be controlled, at which attenuation of sound at that frequency is maximized. It should be noted that this is different from reference to a plurality of webs as shown in Figures 3, 7, and 8.
- adjoining rooms may be constructed (for example, adjoining musical studios) such that each room can be tuned in accordance with its respective mode of use.
- this may be accomplished by constructed "double wall" framework, where two frames of the structure illustrated in Figure 5 are constructed face-to-face, such that the respective opposing sides of the frames are fixed to the surrounding building structure and their respective opposite sides are left free floating in the manner discussed above.
- Assembly of lateral members and resilient webs according to the present invention is facilitated by providing at least one spacer on the resilient web or webs to orient the lateral members relative to the resilient web.
- Figure 10 is a schematic cross-sectional view of a beam 400, somewhat similar to beams 200 and 300 in Figures 6-8.
- beam 400 comprises lateral members 402 and 404, and a resilient web 406 extending therebetween.
- Resilient web 406 is attached to opposite facing sides of lateral members 402 and 404, respectively, by, for example, staples 408 (although any conventional attachment method can be used, including, without limitation, screws, nails, bolts, and the like).
- Resilient web includes a first portion 406a, a second portion 406b bent at an angle to first portion 406a, and a third portion 406c bent at an angle to second portion
- first and second portions 406a and 406b are received in the bends defined by the first and second portions 406a and 406b, and by the second and third portions 406b and 406c, as shown in Figure 10.
- spacer 410 on at least one of first and third portions 406a and 406c to space a respective at least one of the lateral members 402 and 404 away from second portion 406b of the resilient web 406.
- spacers 410 allows easy assembly of the lateral members and the resilient web (known in the art as "self-jigging").
- spacers 410, 412 prevents the respective lateral members 402, 404 from being placed in abutting relation to second portion 406b. If such an arrangement were to be had, then the abutment of the resilient members against the second portion 406b would undesirably retard the resilient sound-damping characteristics of the resilient web 406.
- FIG 10 illustrates a retrofitting assembly 500 comprising a lateral beam 502, to which at least one resilient web 506 is attached by staples 508 or the like.
- Each resilient web 506 as shown includes spacers 510 and 512.. However, the provision of spacers 512 is most important here. It is emphasized that assembly 500 in and of itself is not a construction member per se, but is used in conjunction with standard beams in order to provide a resilient beam arrangement.
- resilient web 506 may be made from any suitably resilient material, including (without limitation) metal, rubber, asphalt, plastic, or other resilient polymeric material.
- spacers 510, 512 are protruding tabs formed integrally with the resilient web 506.
- spacers 510, 512 may be punch-formed into the material of the resilient web 506 (especially, but not necessarily only, where the resilient web 506 is made from metal). The punch-formed portions can simply be turned away from the web material as needed to form the required spacers.
- the assembly 500 is arranged relative to a single standard beam such as a 2"x4" (5.08cm x 10.16 cm) (not shown here) and fastened thereto
- the arrangement of the assembly 500 relative to a standard beam is made simple by the provision of spacers 512, especially where assembly 500 is coupled to a standard beam forming part of a conventional framework.
- the resilient webs 506 may be provided in an alternating arrangement, so that opposite sides of lateral member 502 are attached to respective resilient webs 506, as seen in Figure 9 (this is similar to the arrangement illustrated in Figure 8 and discussed above). With this arrangement, the assembly 500 may be even more easily arranged relative to a standard beam by orienting the assembly 500 so that respective free ends of the resilient webs 506 are arranged on opposite sides of the standard beam. Although the alternating arrangement of resilient webs 506 seen in Figure 9 is beneficial (for reasons similar to those discussed above relative to Figure 8), it is not necessary according to the present invention. The present invention is certainly operable with the resilient webs 506 all arranged in like manner along lateral member 502.
- lateral member 502 may be rectangular or squared in cross-section, and may preferably be made from continuous lumber or a composite wood material, as well as plastic reinforced with glass fibers.
- the spacers 410, 412, 510, 512 may be arranged to space the respective lateral members about 0.25 inches (0.64 cm) from the portion of the resilient web spanning the space between the lateral members.
- the present invention is not restricted to a specific spacing, except for that sufficient to prevent the respective lateral members from fully abutting the resilient web, as discussed above.
- the resilient web 506 may be shaped so as to be attached to lateral members of different profiles.
- a lateral member 502 which is rectangular or squared in cross-section attached to the resilient web 506 may be used so as to be attached to a conventional rigid I-beam (discussed above relative to the related art) or vice versa.
- construction members according to the present invention have been described hereinabove for wall frames and the like, they are also contemplated for use in mounting floating ceilings which are acoustically isolated from a building structure.
- construction members according to the present invention may also be used in floor construction.
- a construction member for mounting a floating ceiling may be used by fixing one of the lateral members to the building structure and fixing a ceiling member to the free floating lateral member (that is, the lateral member not fixed to the building structure).
- the use of substantially identical lateral members is contemplated according to the present invention. However, use of dissimilar lateral members is also expressly within the scope of the present invention.
- one of the lateral members 102, 104 shown in Figure 2 may be replaced by a conventional wood I- beam of the type described above.
- web 106 may be embedded in one of the flange portions of the wood I-beam, in the manner disclosed above.
- metal studs comprising a pair of metal members with a resilient web extending therebetween in accordance with the foregoing description.
- a metal stud using the inventive principles disclosed herein could be made from a single piece of sheet metal, formed into shape.
- Figures 11-14 illustrate a process of retrofitting a preexisting wall in accordance with another embodiment of the present invention.
- Figure 11 is a schematic perspective view of a standard wall structure 600, including first wall member 602, second wall member 604, and a plurality of studs 606 therebetween in a conventional frame arrangement.
- Figure 12 illustrates mounting a plurality of construction members 608 on first wall member 602 in locations corresponding to studs 606.
- construction member 608 each are provided with one or more resilient members 610 mounted on one side thereof.
- the resilient members 610 are fastened onto construction members 608 in any conventional manner (such as, without limitation, nails, screws, staples, adhesive).
- the resilient members 610 act in the same manner as the resilient webs described hereinabove to damp vibrations thereacross.
- each construction member 608 is mounted by of the one or more resilient members 610 onto first wall member 602 (again, in any conventional manner, including, without limitation, screws, nails, staples, adhesive).
- Construction members 608 are arranged in locations corresponding to studs 606 because whatever fasteners are used to mount construction members 608 (by way of resilient members 610) are preferably driven through first wall member 602 into respective studs 606 in order to create a high-strength arrangement. However, where mechanically suitable, it may not always be necessary to locate construction members 608 in correspondence with studs 606.
- construction members 608 define spaces therebetween in a manner similar to those defined between studs 606. It is desirable, therefore, to provide additional insulation (including, without limitation, batts or blown insulation) between construction members 608 in order to increase sound and/or thermal insulation characteristics.
- Figure 13 illustrates an example where insulation batts (for example, fiberglass batts) 612 are provided between construction members 608.
- a third wall member 614 is mounted by way of construction members 608 in a conventional manner.
- Third wall member 614 may be any type of conventional wall material, such as, without limitation, drywall or plywood.
- Resilient members 610 may be of any configuration that resiliently separates construction member 608 from first wall member 602. It is a particular feature of the present invention to provide construction members 608 and resilient members 610 which are collectively sized and shaped so as to define a space between first wall member 602 and third wall member 614 suitable for providing sound and/or thermal insulation therebetween, as discussed above relative to Figures 13 and 14. In one example according to the present invention, resilient members 610 space construction members 608 from first wall member 602 between 1.5 inches to 2.5 inches (3.81 cm to 6.35 cm) away.
- resilient members 610 are shaped so as to provide portions thereof for readily mounting the resilient member 610 onto both construction member 608 and first wall member 602.
- Figures 15a- 15c illustrate examples of a resilient channel suitable for use as resilient member 610.
- construction member 608a and resilient channel 610a are provided with aligned through holes 616a through which a fastener (such as, without limitation, a screw or nail) is passed for mounting the construction member 608a.
- resilient channel 610b is provided with a through hole 616b, again for passing a fastener therethrough.
- the resilient channel may be fastened to first wall member 602 before mounting a respective construction member 608b thereon.
- resilient channel 610c includes a portion offset from the mounting location of construction member 608c, in which a through hole 616c is provided. Therefore, the resilient channel 610c need not be separately mounted on first wall member 602 from construction member 608 c, unlike the arrangement illustrated in Figure 15b.
- Figures 16a and 16b are other examples of resilient channels 610d, 610e that can used as resilient members 610, in accordance with the present invention.
- Each provides a first flange 618a, 618b spaced apart from a second flange 620a, 620b.
- the first and second flanges provide mounting locations for construction member 608 and first wall member 602.
- a construction member 608 may be omitted when using resilient channels 610d and 610e, such that one of the flanges is fastened to the first wall member 602 and one of the flanges is fastened directly to third wall member 614.
- FIG 17 is an example of a resilient web 61 Of somewhat similar to that shown in Figures 9 and 10.
- Resilient web 61 Of includes a flange 624 by which the web 623 is attached to first wall member 602.
- Resilient members 610 are made in accordance the considerations discussed above relative to the resilient web of the resilient construction member.
- Resilient members 610 may be beneficially provided with spacers as discussed above relative to Figures 9 and 10.
