Description

455 108 Det har visat sig att tillsättandet av U-profiler i ljudisole- ringselement ökar elementens ljudisolering betydligt. Speciellt fördelaktigt är ett sådant arrangemang vid vilket U-profilerna anordnats turvis vid varje yttre skikts (till exempel bergull) inre och yttre sida. Med detta arrangemang lyckas man öka elemen- tets ljudisolering från värdet 39 dB till värdet 44 dB. 455 108 It has been shown that the addition of U-profiles in sound insulation elements significantly increases the sound insulation of the elements. Particularly advantageous is such an arrangement in which the U-profiles are arranged alternately at the inner and outer side of each outer layer (for example rock wool). With this arrangement, you manage to increase the element's sound insulation from the value 39 dB to the value 44 dB.

Limmandet av U-profiler vid det yttre skiktet ökar dessutom ele- mentets styvhet.The gluing of U-profiles to the outer layer also increases the rigidity of the element.

Uppfinningen förklaras i det följande närmare genom att hänvisa till bifogade ritningar, i vilka figur l föreställer ett ljudisoleringselement sett framifrån, figur 2 föreställer en genomskärning av ett ljudisoleringselement, och figur 3 föreställer en genomskärning av ett ljudisoleringselement vid vilket U-profilerna anordnats på annat sätt än i figur 2.The invention is explained in more detail below by referring to the accompanying drawings, in which figure 1 represents a sound insulation element seen from the front, figure 2 represents a cross-section of a sound insulation element, and figure 3 represents a cross-section of a sound insulation element in which the U-profiles are arranged in another way than in Figure 2.

I figur l ses ljudisoleringselementet 1 framifrån. Där har även ritats de in i elementet anordnade U-profilerna 6, 8, 10. U-profi- lerna har_tryckts in i det yttre skiktets bergull. Genom att limma U-profilerna vid det yttre skiktet åstadkommas en bättre styvhet för elementet.Figure 1 shows the sound insulation element 1 from the front. The U-profiles 6, 8, 10 arranged in the element have also been drawn there. The U-profiles have been printed into the rock wool of the outer layer. By gluing the U-profiles to the outer layer, a better rigidity of the element is achieved.

Figur 2 föreställer en genomskärning av ett ljudisoleringsele- ment. Elementet består av två yttre skikt 3 och 5, vilka är berg- ull. Mellan dessa har anordnats ett glasullsskíkt 4. I figuren ses även U-profilerna 6, 8 och 10 samt de mot dessa belägna U- profilerna 7, 9 och ll.Figure 2 shows a cross-section of a sound insulation element. The element consists of two outer layers 3 and 5, which are rock wool. A glass wool layer 4 has been arranged between these. The figure also shows the U-profiles 6, 8 and 10 and the U-profiles 7, 9 and 11 located opposite them.

Genom att anordna U-profilerna turvis på den yttre och den inre sidan av varje yttre skikt åstadkommes ca 2 dB bättre ljudisole- ring (44 dB) än om alla U-profiler skulle ordnats på samma sidan om respektive yttre skikt. Ur produktionsteknisk synpunkt har U- 455 108 profilerna anordnats.mot varandra vid de båda yttre skikten. Det är även möjligt att anordna U-profilerna turvis, t.ex. som visats i figur 3. Med sistnämnda arrangemang åstadkommes en ljudisole- ring av samma klass som enligt arrangemanget i figur 2.By arranging the U-profiles alternately on the outer and the inner side of each outer layer, approx. 2 dB better sound insulation (44 dB) is achieved than if all U-profiles were arranged on the same side of the respective outer layer. From a production technical point of view, the U-455 108 profiles have been arranged against each other at the two outer layers. It is also possible to arrange the U-profiles alternately, e.g. as shown in Figure 3. With the latter arrangement, a sound insulation of the same class is achieved as according to the arrangement in Figure 2.

Det har visat sig att om man använder U-profiler av något rela- tivt tungt material, t.ex. stål, är deras ljudisoleringsegens- kaper betydligt bättre än om man använder U-profiler av något lättare ämne, t.ex. aluminium eller plast. Aluminium är dessutom dyrare och det uppvisar ej samma brandsäkerhetsegenskaper som stål. Om man använder U-profiler av stål, är den tyngdökning som de åstadkommer ca 25 %, varför elementens tyngd stiger från 21 kg/ m till 26 kg/m . Detta värde blir under det värde som kan godkännas för en man att lyfta i fortgående monteringsarbete, varför elementet enligt uppfinningen ej förosakar tilläggskostna- n der vid monteringen i form av extra arbetskraft.It has been shown that if you use U-profiles of some relatively heavy material, e.g. steel, their sound insulation properties are significantly better than if you use U-profiles of a lighter material, e.g. aluminum or plastic. Aluminum is also more expensive and does not have the same fire safety properties as steel. If you use U-profiles of steel, the weight gain they achieve is about 25%, so the weight of the elements rises from 21 kg / m to 26 kg / m. This value is below the value that can be approved for a man to lift in continuous assembly work, which is why the element according to the invention does not cause additional costs during assembly in the form of extra labor.
