Definitions

  • the present invention relates to structural systems used in construction, especially including combinations of beam-type construction members (either alone or used together in frames) and board members, such combinations being used to define structural walls, ceilings, floors, etc.
  • the present invention also relates to board members used in construction which have particular sound attenuating characteristics.
  • 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.

  • a beam member according to the present invention comprises a pair of spaced of lateral members having a resilient web extending therebetween.
  • the web is preferably relatively stiff, but permits a slight flexure between the lateral members.
  • the lateral members are preferably made from an easily workable material such as wood.
  • the present invention contemplates a board member mounted on the beam members according to the present invention.
  • a board member is provided comprising first and second relatively rigid layers, the first and second layers having a visco-elastic material layer interposed therebetween.

  • Figures 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 squared in cross-sectional profile and have at least the same thickness y (see Figure 2). Moreover, 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. Accordingly, beam 100 presents a cross section having a major dimension x and minor dimension y corresponding to any standard beam size (for example, 2 in x 4 in or 2 in x 6 in (5.08 cm x 10.16 cm or 5.08 cm x 15.24 cm), and so on, without limitation).
  • any standard beam size for example, 2 in x 4 in or 2 in x 6 in (5.08 cm x 10.16 cm or 5.08 cm x 15.24 cm
  • 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, etc.). Not only can continuous lumber be used, but composite materials, such as plywood or wood particle board can be used. In addition, finger 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.
  • 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 ft (2.44 meter) as seen in Figure 3 and can be cut down as required.
  • Figure 5 is a partial perspective view of a frame (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 100a- 100c 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 board member mounted on one side of the frame is attenuated upon transmission to the other side of the frame because of the dissipative resilience of webs 106', 106", and 106'".
  • a wall so that it acts like a diaphragmatic sound absorber.
  • only one "side" of the frame assembly (for example, lateral member 104c and/or lateral members 104a, 104b) is fixed to the surrounding 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
  • the wall surface is visually continuous, but physically decoupled, in order to take advantage of the resultant sound attenuation effects.
  • Such insulation can be of any conventional type, including blown, rolled or batting, foam board, etc. The addition of such insulation enhances sound attenuation effects resulting from the present invention.

  • 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 crisscross 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.

Abstract

L'invention porte sur des systèmes structuraux pour le bâtiment comprenant des combinaisons d'éléments de type poutrelle (isolés ou combinés pour former des structures) et de panneaux. Ces combinaisons peuvent par exemple servir pour créer des murs, des plafonds, des planchers, etc. Les poutrelles (100) et les panneaux (400) ont tous des caractéristiques d'atténuation des sons. Une poutterelle (100), qui comprend une paire de semelles (102, 104) et une âme souple (106) les reliant présente une section analogue à celle des profils normalisés du bâtiment (par exemple 5,08 cm x 10,16 cm ou 5,08 cm x 15,24 cm). L'élasticité de l'âme (106) contribue à atténuer la propagation des sons d'une semelle (102, 104) à l'autre. Un assemblage de telles poutrelles (100) sert de cadre de montage aux panneaux selon des techniques usuelles. Un panneau (400) présente une structure muiticouche (par exemple une première et une deuxième couche rigide (402), et une couche d'un matériau visco-élastique les séparant), qui renforce l'atténuation des sons.
