  • a 428 I220 partitions is composed of two boards of substantially 51 1111. C1 EOib 2/23; e046 2/34 Same Size filmed together face face with a 58 Field 61 Search 52/615 403 405 144- imerspace' by means 01 misled Or braided 16l/39 4O 44 56 142 soaked in an elastically hardening, semi-fluid cement 7 181733 6 and stretched between the boards in widely spaced, parallel positions, at least the one of said boards, viz.
  • This invention relates to. sound qed'u'cing, composite covering panels for internal use inbuildi'ngs and particularly usefulfor coveringifr amedpartitions. More specifically the invention relates toeti'mposite' covering panels of the kind comprising t woboards of substantially the same planar size jointed together in face to face relationship by means of spacer elements maintaining between the boards an openspace that is small as compared with the thickness of the respective boards, and in which at least one of said boards, viz. the one intended to :face a room in the building. has a relatively low flexural strength.
  • a board is, at least in this specification and in the appendedclaims, considered to have relatively low flexural strength, or in other words a relatively low stiffness combined :with a certain elasticity, if it is capable, under the influence -of sound transmitted thereto, to produce bending waves of a wave-length shorter than that ofthesouncl in air.
  • a board having such a feature will, if properly permitted, to exhibit its capacity in that respect; considerablyreduce the sound radiated from its exposed face to the confronting air and, hence, highly assist in sound insulating building rooms.
  • a typical exponent of the feature in question is an ordinary gypsum plasterboard, but there are many other types of boards of various materials and compositions meeting the same requirements as to a relatively high density, a relatively small thickness, and a low modulus of elasticity.
  • the cords forming, in combination with the elastically hardening adhesive composition, the spacer elements have proved toassiee an extremely strong connection between the two boards, which is believed to primarily depend on the non-axial orientation of the strands of the cordsand nthe, fact that the adhesive composition will; as'a' result of capillary phenomena, form between each'board and cord ori'either side of the latter a recessed elastic fillet firmly adhering both to the board face and to the related portion of cord circumference. ln fact.
  • the cords together with the elastically hardening adhesive composition will form a kind of hinges adhesively attached to both the opposed board faces by means of laterally extended wings, and this hinge-like action of the spacer elements is extremely advantageous for the freedom of flexure of at least the relatively weak board.
  • the cords will, due to their elastical compressibility, act as linear cushions between the boards, and. consequently, to a certain degree reduce the sound transmission between the boards.
  • At least the one board having the relatively low flexural strength is a gypsum plasterboard.
  • both the two boards can have a relatively low flexural strength, eg be gypsum plasterboards, so that there is no need for knowing which side of the panel should face the room, when the panel is installed.
  • the cords to be used when carrying out the invention can be built up by strands being twisted or braided together and the material of the cords may benatural as well as synthetic fibres.
  • the adhesive composition used for securing the cords may suitably be an elastomeric cement based on rubber or plastics and having, when applied, a viscous or semi-fluid character.
  • the outermost cords between the two boards are located inwardly of the lateral edges of the boards so as to leave an open groove inthe panel edges.
  • the thickness. of each cord is preferably in the order of one thirty-second to one-eighth inch.
  • the hinge-like connections formed between the two boards of a panel embodying this invention will form a kind of flexural nodes, when bending waves are produced in at least the one board in response to sound transmitted thereto. From this follows that the spacing of the cords, i.e. the mutual distance between the parallel hinges," should be adapted to the flexural properties of the board or boards. If, for example, the board producing bending waves is, as preferred, a gypsum plasterboard having a thickness in the order of one-half to three-fourths inch, the spacing of the cords should be in the order of 3 to 7 inches.
  • FIG. 1 shows an end view of the covering panel
  • FIG. 2 is a fragmentary cross section of the same panel on an enlarged scale
  • FIG. 3 is a vertically shortened plan or front view of the panel which is partially broken through and shown on a reduced scale.
  • FIG. 4 is a fragmentary perspective view of one form of a cord spacer element in accordance with my invention.
  • the composite covering panel embodying the invention is made in lengths approximately correever, the sizes and the manner of installation of the panels is not in itself critical for utilizing-the improved properties of the panels embodying the invention.
  • the panel comprises two boards 1 and 2, respectively, having substantially the same planar size. At least one of the boards, viz. that which is intended to face a room in the building, which is supposed to be board 1 in the drawing, has a low flexural strength, while the other board 2 can, in principle, be of any desired kind. Preferably, however, also the second board 2 has a low flexural strength.
  • both the boards 1 and 2 are paper covered gypsum plasterboards of the same thickness.
  • the board I intended to face the room can have bevelled side edges and a slightly larger width than the other board 2, for example in order to more easily permit concealing of attachment or connection elements required for the installation of the panels in'the respective joints between adjacent panels. This. has been most clearly illustrated in FIG. 2, where Ialso an attachment element is shown in dash-and-dot lines and designated by F.
  • the two' boards land 2 are jointed together in face to facewrelationship bymeans of widely spaced twisted or braided cords 3 having at least approximately a round cross section.
  • the cords 3 are secured in stretchedpparallel positions between the boards by meansxof an elastically hardening adhesive composition or'cement4 (FlG. 2) to serve as spacer elements maintaining between .the boards an open space 5 that is passag'es'thus formed in the panel are suitably not closed 'atthe ends of the panel, although there is nothing to preventclosing of the passages at the panel ends, if so desired.
  • the twisted or braided cords 3 are suitably soaked with the elastically hardening adhesive composition by being passed through a bathe of the cement, which is preferably a semi-fluid elastomeric glue.
  • a bathe of the cement which is preferably a semi-fluid elastomeric glue.
  • the cement-soaked cords 3 in stretched positions have been interposed between the boards, the adhesive composition or cement will, because of capillary phenomena, not only adhere to the opposed board faces but also form between each board and the intermediate cord on either side of the latter a recessed fillet, approximately as shown in FIG. 2.
  • the outermost cords 3 between' the two boards 1 and 2 of the panel are located slightly inwardly of the side'edges of the boards so as to leave an open groove in the panel edges. This is particularly useful for accomodatin'g the attachment or connection elements F as illustrated in FIG. 2.
  • the cords interposed'between the two outermost ones are suitably evenly spaced as shown, and the spacings between the cords should be selected to take advantage of the flexural properties'of the boards in the most favorable manner.
  • a spacing of the cords in the order of approximately 4 inches.
  • the same spacing may be used also if only the front board 1 has flexural properties while the other or backing board 2 is a stiffer one, which may beadvantageous in some installations. If the thickness of the front board is increased, it is usually advisable to also increase the spacing between the cords.
  • a sound reducing, composite covering panel for internal use in buildings comprising:
  • first planar sheet of gypsum plasterboard b. a second planar sheet of gypsum plasterboard, c. said first and second sheets having substantially the same size and being between about one-half and three-fourths inch thick, d. said first and second sheets being positioned in a face-to-face spaced apart relationship, e. a plurality of cord spacer elements interposed between said spaced apart first and second sheets, f. said cord spacer elements 1. being spaced apart along substantially parallel lines that are between about 3 and 7 inches apart,
  • a sound-reducing, composite covering panel for internal use in buildings comprising:
  • said cord spacer elements 1. being spaced apart between about 3 and 7 inches, stretched and essentially parallel,
  • each of said cord spacer elements being secured to each of said two boards by means of an elastically hardening adhesive composition which forms between each cord spacer element a recessed elastic fillet firmly adhering both to the board face and to the adjacent portion of the cord spacer element, whereby each cord spacer element will form a highly flexible hinge-like connection between the two facing surfaces of said boards.
