Abstract
The invention relates to a sound-damping partition, especially for the internal equipment of buildings. The partition consists essentially of a timber sub-frame (10) and two sets of planking (18, 20) on either wide side (12, 14) of the sub-frame (10) leaving a hollow space (16) filled with air and damping materials (36). To obtain improved airborne sound damping using simple means, the invention proposes that one of the sets of planking (20) be secured to the sub-frame (10) by means of thick-walled, soft elastic beads of adhesive (32) while the other set of planking (18) is rigidly clamped to said sub-frame (10).
Description
Sound-damping partition wall Description The invention is related to a sound-damping partition wall, especially for interior structures in buildings, comprising a sub-frame preferably designed to be a wooden frame or post construction, and two sets of planking on either broad side of the sub-frame, leaving therebetween a hollow space filled with air and/or damping material.
In known partition walls of this type the planking is connected by mechanical means such as staples, nails, or screws to the wooden sub-frame. The acoustic damping val-ues of such partition walls is not satisfactory, though,even when using thick-walled multiple planking. The sound attenuation that can be achieved therewith is in the or-der of 46 dB. An improvement of the damping values was in the past only possible with sub-frames in which the posts were replaced by profiled posts made of metal. The sound damping is therein improved by the internal elasticity of the profiled posts, which dampens the flexural vibra-tions, which are mainly responsible for the transmission of sound, when the planking is rigidly coupled to the posts. In the metal sub-frames it is found to be disad-vantageous, though, that these, as opposed to the wooden sub-frames, cannot be used as load bearing walls. There-fore metal sub-frames are not liked to be used especially in the construction of pre-fabricated houses, more so since it would not fit into the production process of the building company which is usually equipped to work with wood.
Based on this it is the object of the invention to im-prove a partition wall of the type described above such that an increased sound-damping can be achieved with sim-ple means.
. CA 02228311 1998-01-30 For the solution of this object the combination of fea-tures stated in patent claim l is proposed. Advantageous embodiments and further developments result from the de-pendent claims.
The solution according to the invention is based on the idea that the sound decoupling between the two plankings and the sub-frame can be improved when the two plankings can vibrate independently from each other. In order to achieve this, it is proposed according to the invention that at least one set of the planking is connected to the sub-frame by means of thick, softly elastic adhesive beads. The other planking is expediently connected rig-idly to the sub-frame, preferably by means of staples, nails or screws, and thereby serves as a reinforcement plane for the static calculation.
An adhesive which has a shear modulus of O.l to 0.3 N/mm2 at room temperature has proven to be especially advanta-geous. This value as well as the hardness according to the invention of lO to 30 Shore (A) is very low compared to the adhesives usually used in wood connections and corresponds more to the values of elastic sealant materi-als. Due to the fact that the wall thickness o~ the adhe-sive beads corresponds to approximately 0.3 to l.2 times their width and is about 3 to lO mm in actual application cases, a certain amount of shear deformation within the adhesive beads has to be taken into account due to the weight of the planking.
In order to keep the shear deformation within acceptable limits, it is proposed according to a preferred embodi-ment of the invention that the adhesive surface areas A
of the adhesive beads are dimensioned such that under the influence of the weight of the planking a shear deforma-tion of the adhesive beads of 5 to 25 % of the bead thickness results. In other words, the adhesive surface area of the adhesive beads as a function of a unit area of the planklng is advantageously A = l/~ x F/G with ~ = 0.05 to 0.25, wherein F denotes the weigth per unit area o~ the plank-ing, G the shear modulus of the adhesive and ~ the shear deformation of the adhesive beads as a function of the bead thickness at room temperature.
For a given bead size having an adhesive sur~ace area A' per bead the number of beads per surface unit can be de-termined to be~5 n = l/~A' x F/G with ~ = 0.05 to 0.25.
The adhesive beads have on both contact sides essentially rectangular adhesive surfaces, wherein the aspect ratio between the long and the short side is expediently chosen to lie between 4:l and 16:l. Advantageously, the long sides of the adhesive beads are vertically aligned with respect to the sub-frame and disposed vertically spaced with respect to each other on the vertical posts of the sub-frame. Two laterally spaced rows of adhesive beads may be disposed on each post of the sub-frame, wherein adjacent adhesive beads of the two rows of adhesive beads can be staggered in a zig-zag fashion with respect to each other.
Double-sided foam adhesive strips disposed vertically on the posts of the sub-frame and acting as an aid during assembly may be provided in addition to the adhesive beads, which has a spacer function apart from keeping the planking in place until the adhesive beads have set. The adhesive beads are applied to the sub-frame in the form of triangular beads with the tip protruding over the ad-hesive foam strips, and are deformed to the wall thick-ness of the adhesive foam strips when the planking is mounted, wherein the adhesive surface at the tip side is broadened.
Since the shear modulus of the adhesive decreases with increasing temperature and the shear deformation in-creases accordingly due to the own weight, a stop shoul-der for the glued planking can be disposed on the sub-frame as a safety measure, which stop shoulder is either elastically resillient or which is diposed below the lower edge of the glued planking at a distance corre-sponding to at least the bead thickness.
The adhesive is expediently chosen from the group of polyurethane adhesives, silicone adhesives, butylene ad-hesives or a mixture of these adhesives, while the plank-ings may consist of or are composed of gypsum plaster boards, gypsum fiber boards, particle boards or plywood boards.
In the following the invention is further described with reference to an embodiment schematically shown in the drawing, in which:
Fig. l shows a broad side view of a sound-damping par-tition wall with a partially broken away front planking;
Fig. 2a and b show a cross section and a plan view of an enlarged detail of the partition wall of Fig. l with the front planking removed;

The sound-damping partition wall shown in Fig. 1 is in-tended to be used for the interior construction of pre-fabricated houses. It consists essentially of a sub-frame 10 designed as a wooden frame and two plankings 18, 20 mounted thereto at the broad sides 12, 14, with an air filled hollow space 16 formed therebetween. The frame forming the sub-frame 10 comprises a lower beam 22, an upper beam 24 and a plurality of posts 26 extending be-tween the lower and upper beams and rigidly connected thereto. The plankings 18 and 20 are each made of two gypsum plaster boards and/or plywood boards which lie plane against each other and which are rigidly connected to each other by staples 28, 30 or other mechanical fas-teners. The planking 18 is rigidly connected to the sub-frame 10 by means of the sufficiently long staples 28, while the planking 20 is connected to the sub-frame 10 by means of soft-elastic, thick-walled adhesive beads 32. In order to make the assembly of the glued planking easier, double-sided adhesive foam strips 34 are additionally provided, which serve as spacers and immediate fixing of the planking 20 to the sub-frame 10 until the adhesive beads 32 have set. The adhesive beads 32, which prefera-bly consist o~ a polyurethane adhesive, are applied to the horizontally positioned sub-frame in the form of tri-angular beads with their tips protruding over the adhe-sive foam strips 34 and are deformed to their rectangular cross section according to Fig. 2a when the planking 20 is put on.
In the embodiment of Fig. 2a the hollow space 16 is par-tially filled with an insulating mat 36 consisting, for instance, of glass fiber material.
; CA 02228311 1998-01-30 Example For the production of a sound-damplng partition wall a frame construction made of wood with square wood posts havlng sides of 80 mm length and being arranged at dis-tances of 62.5 cm from each other is rigidly stapled at one broad side 14 to a double planking made of 12.5 mm thick gypsum plaster boards and glued on the other side to a similarly constructed planking consisting of two 12.5 mm thick gypsum plaster boards by means of adhesive beads 32 and an adhesive foam strip 34. The 70 mm long and 8 mm wide adhesive beads are applied as triangular beads with a tip height of 12 mm to the post surfaces 14 in the zig-zag shape shown in Fig. 2b on the left and right side of the corresponding adhesive foam strip 34.
The same procedure is carried out on the upper and lower beams 22, 24. A two component polyurethane adhesive (SikaBond VP200195)is used as the adhesive, which is ap-plied in pasty form. When the planking 20 is mounted, the adhesive beads 32 are deformed to the thickness (6 mm) of the double-sided adhesive foam strip 34 which acts as a spacer.
The shear modulus of the adhesive used was G = 0.19 N/mm2 in the set state. The adhesive area A' of each bead was 70 mm x 8 mm = 560 mm 2, The breaking elongation of the adhesive used was more than 500 %, while the breaking elongation of glued gypsum plaster boards is more than 150 %.
The admissible shear deformation by the own weight of the planking was assumed to be ~ = 0.1, which corresponds to an admissible shear deformation of 0.6 mm for a bead thickness of 6 mm. The admissible deformation depends on visual inspectlon (usablllty) and on the maxlmum deform-ablllty of the connectlons (in this case gypsum). Thus there ls at worst a 15-fold breaklng securlty.
From these values the adheslve surface area of the adhe-sive beads amounts to A = F/(0.1 G) wherein A denotes the adheslve area in mm2/m2, F the area eight of the planklng ln N/m2, and G the shear modulus of the adheslve (here G = 0.19 N/mm2).
The number of adheslve beads per square meter planklng is calculated to be n = A/A' wherein A' denotes the adhesive surface area of each bead (here 560 mm2).
The examined partition wall had a surface area of 12.1 m2 and a total weight (denslty) of 51.5 kg/m3. The sound at-tenuation measurements were performed according to ISO/DIS 140-3 (1993) with an evaluation according to ISO/DIS 717-1 (1193) uslng wide band noise as test sound and a third-band filter on the receiver side. The results are shown ln the dlagram of Flg. 3. A comparlson wlth the norm reference curve Bv shown in dash-dotted line shows an average sound attenuation Rw = 52 dB. This sound at-tenuation value is at least 6 dB larger than for a corre-sponding partition wall in which both plankings 18, 20 are stapled to the sub-frame.
In summary the followlng ls to be stated: The invention ls related to a sound-damplng partltlon wall, especially for lnterior structures in buildings. The partition wall comprises a wooden sub-frame 10 and two sets of planking 18, 20 on either broad side 12, 14 of the sub-frame 10, leaving therebetween a hollow space 16 filled with air and damping material 36.
