Description

Veggbekledningspanel for inner- og mellomvegger i bygninger. Wall cladding panel for internal and intermediate walls in buildings.

Foreliggende oppfinnelse angår veggbekledningspaneler med akustikkforbedrende og lystransmisjonsreduserende egenskaper for inner- og mellomvegger i bygninger, nærmere bestemt sådanne veggbekledningspaneler, som består av to plater med i hovedsaken samme utbredelse, hvilke plater med et i forhold til platenes tykkelse lite mellomrom er sammenføyet planside mot planside under formidling av glissent plasserte distanseholdende mellomlegg, og av hvilke plater i det minste den ene, nemlig den som er bestemt å vende ut mot rommet, utgjøres av en plate med bøyningselastiske egenskaper, fortrinnsvis en gipsplate. Oppfinnelsens formål er å tilveiebringe et veggbekledningspanel av den angitte art, ved hvilket den bøyningselastiske plates egenskaper fra et akustisk synspunkt ivaretas på gunstigst mulige måte og bygger på den iakttagelse at det råder et motsetnings-forhold mellom ønsket om størst mulig svingningsfrihet for den bøyningselastiske plate og holdfastheten i forbindelsen mellom bekledningspanelets to plater. The present invention relates to wall cladding panels with acoustic-improving and light-transmission-reducing properties for internal and intermediate walls in buildings, more specifically such wall cladding panels, which consist of two boards with essentially the same width, which boards are joined with a small gap in relation to the thickness of the boards, side to side under provision of slip-placed distance-holding spacers, and of which plates at least one, namely the one destined to face the room, is made up of a plate with flexural elastic properties, preferably a plasterboard. The purpose of the invention is to provide a wall cladding panel of the specified type, whereby the properties of the flexurally elastic plate from an acoustic point of view are safeguarded in the most favorable way possible and is based on the observation that there is a conflict between the desire for the greatest possible freedom of oscillation for the flexurally elastic plate and the strength of the connection between the cladding panel's two plates.

I overensstemmelse med foreliggende oppfinnelse, som har vist In accordance with the present invention, which has shown

seg å gi overordentlig gode resultater, løses det aktuelle prob-lem ved at de distanseholdende mellomlegg utgjøres av tvunne eller flettede snorer med i det minste tilnærmelsesvis rundt tverrsnitt, hvilke snorer er fiksert i strukne, innbyrdes parallelle stillinger mellom platene ved hjelp av elastiske herdnende bindemiddel. able to give extremely good results, the relevant problem is solved by the distance-holding spacers consisting of twisted or braided cords with at least approximately round cross-sections, which cords are fixed in stretched, mutually parallel positions between the plates by means of elastic hardening binders .

De angjeldende snorer har vist seg i forbindelse med bindemidlet The cords in question have appeared in connection with the binder

å sikre en overordentlig holdfast forbindelse mellom platene, hvilket først og fremst turde skyldes den ikke aksiale fiber-orientering i snorene, og derved sikres en absolutt minimal bredde av de enkelte forbindelser mellom platene regnet i panelplanet. to ensure an exceptionally strong connection between the plates, which was primarily due to the non-axial fiber orientation in the cords, thereby ensuring an absolutely minimal width of the individual connections between the plates calculated in the panel plane.

I realiteten danner snorene sammen med det elastiske herdnende bindemiddel som følge av kapillaritetsfenomener et slags "heng-sel" som er overordentlig fordelaktig for den eksponerte, bøy-ningselastiske plates svingningsfrihet, idet forbindelsene danner et slags svingningsledd. Derav følger også at den innbyrdes avstand mellom de parallelle "hengsler" bør tilpasses etter den eksponerte plates svingningsegenskaper. In reality, the cords together with the elastic hardening binder form, as a result of capillarity phenomena, a kind of "hinge" which is extremely advantageous for the freedom of oscillation of the exposed, flexurally elastic plate, as the connections form a kind of oscillation joint. It also follows that the mutual distance between the parallel "hinges" should be adapted to the oscillation characteristics of the exposed plate.

For oppfinnelsens klargjøring beskrives i det følgende og under henvisning til tegningen et utførelseseksempel på et veggbekledningspanel ifølge oppfinnelsen. På tegningen viser fig. 1 et ende-riss av veggbekledningspanelet, fig. 2 et i forhold til fig. 1 sterkt forstørret, partielt tverrsnitt av samme panel, og fig. 3 et delvis gjennombrutt og i høyderetningen sammentrukket front-riss av panelet i sterk forminskning. In order to clarify the invention, an embodiment of a wall covering panel according to the invention is described below and with reference to the drawing. In the drawing, fig. 1 an end view of the wall cladding panel, fig. 2 et in relation to fig. 1 highly enlarged, partial cross-section of the same panel, and fig. 3 a partially broken-through and vertically compressed front view of the panel in a greatly reduced form.

Normalt utføres veggbekledningspanelet ifølge oppfinnelsen i lengder, som tilnærmelsesvis svarer til romhøyden i den bygning, der panelene skal anvendes for bekledning av inner- og mellomvegger, idet panelbredden i de fleste tilfelle velges vesent- Normally, the wall covering panel according to the invention is made in lengths that correspond approximately to the height of the room in the building where the panels are to be used for covering inner and intermediate walls, the panel width being chosen in most cases essentially

lig mindre enn nevnte lengde og panelene ved oppsetningen plas-seres stående side ved side. En sådan dimensjonering og anvend-else er imidlertid ikke nødvendig for å ivareta de forbedrede egenskaper av veggbekledningspanelet som foreliggende oppfinnelse gir. equal to less than the mentioned length and the panels are placed standing side by side during installation. However, such dimensioning and use is not necessary to ensure the improved properties of the wall covering panel that the present invention provides.

Som det fremgår av tegnings figurene består veggbekledningspanelet av to plater 1 resp. 2 med i hovedsaken sammen utbredelse, idet 1 det minste den ene plate 1, nemlig den som er bestemt å ekspo-neres mot rommet, når veggbekledningspanelet oppsettes, utgjøres av en plate med bøyningselastiske og dermed akustisk verdifulle egenskaper, mens den andre plate 2 i prinsippet kan være av hvilket som helst slags, men fortrinnsvis også har bøyningselastiske egenskaper. I det viste eksempel forutsettes begge plater 1 resp. 2 å være papiromkledde gipsplater, som nettopp har slike bøy-ningselastiske egenskaper. As can be seen from the drawing figures, the wall covering panel consists of two plates 1 or 2 with essentially the same distribution, as 1 at least one plate 1, namely the one that is destined to be exposed to the room, when the wall cladding panel is set up, is made up of a plate with flexurally elastic and thus acoustically valuable properties, while the other plate 2 in the principle can be of any kind, but preferably also has flexural elastic properties. In the example shown, both plates 1 or 2 to be paper-covered plasterboard, which has exactly such bending-elastic properties.

Den for eksponering bestemt plate 1 kan, slik som vist i fig. 1 og 2, ha avfasede sidekanter og et noe større breddemål enn den andre plate 2, eksempelvis for at de for bekledningspanelenes fastgjøring og/eller innbyrdes forbindelse ved oppsetningen for-drede feste- eller forbindelseselementer lettere skal kunne skjules i skjøtene mellom panelene. Dette er antydet i fig..2, der et slikt festeelement, som er vist med strekpunktlinjer, er betegnet med F. The plate 1 intended for exposure can, as shown in fig. 1 and 2, have chamfered side edges and a somewhat larger width than the second plate 2, for example so that the fixing or connection elements required for the cladding panels' fastening and/or mutual connection during installation can be more easily hidden in the joints between the panels. This is indicated in fig..2, where such a fastening element, which is shown with dotted lines, is denoted by F.

De to plater 1 og 2 er innbyrdes sammenføyet planside mot planside under formidling av glissent plasserte distanseholdende mellomlegg i form av tvunne eller flettede snorer 3 med i det minste tilnærmelsesvis rundt tverrsnitt, hvilke snorer er fiksert i strukne, innbyrdes parallelle stillinger mellom platene ved hjelp av elastisk herdnende bindemiddel 4 (fig. 2). Snorene 3, som fortrinnsvis forløper i panelets lengderetning, tjener i første rekke som distanseholdende mellomlegg, som mellom platene opprettholder et i forhold til platenes tykkelse lite mellomrom 5. The two plates 1 and 2 are mutually joined plane side to plane side under the mediation of gapped spacers in the form of twisted or braided cords 3 with at least approximately round cross-section, which cords are fixed in stretched, mutually parallel positions between the plates by means of elastic hardening binder 4 (fig. 2). The cords 3, which preferably run in the longitudinal direction of the panel, primarily serve as spacers, which maintain a space 5 that is small in relation to the thickness of the plates between the plates.

Dette mellomrom 5 er uutfylt så nær som på snorene 3, og de mellom de ulike snorer herved dannede kanaler er hensiktsmessig åpne ved panelets ender. This space 5 is unfilled as close as the cords 3, and the channels formed by this between the various cords are appropriately open at the ends of the panel.

Når de tvunne eller flettede snorer 3 i strukne stillinger og When the twisted or braided cords 3 in stretched positions and

Gjennom kappi-larvirkningen oppnås nemlig mellom snoren og hver plate en slags hulkiledannende utfylling med bindemidlets hjelp, omtrent som vist i fig. 2. Tvinningen eller flettingen av snorene 3 er selv- saddle joint of small width and with great mobility. Through the capillary action, a kind of hollow wedge-forming filling is achieved between the cord and each plate with the help of the binder, approximately as shown in fig. 2. The twisting or braiding of the cords 3 is self-
