Schalldämmendes BauelementSound absorbing component

Die Erfindung betrifft ein aus zwei oder mehreren Glasplatten oder -scheiben bestehendes schallisolierendes Bauelement .The invention relates to a sound-insulating component consisting of two or more glass plates or panes .

In der Bauakustik gelten in dem Frequenzbereich vonIn building acoustics apply in the frequency range of

100 - 3.150 Hz bestimmte Forderungen hinsichtlich der Schall- | dämmung. Die Schalldämmung ist frequenzabhängig. Bei Plattendicken unter 4 mm ist die Luftschalldämmung für eine gegebene % Frequenz nur von dem Gewicht der Platte pro Flächeneinheit abhängig. Die Schalldämmung R nimmt bei jeder Verdoppelung der Frequenz um ein Inkrement von 6 dB zu, und zwar nach der Formel100 - 3,150 Hz certain requirements with regard to the sound | insulation. The sound insulation is frequency-dependent. For panel thicknesses below 4 mm, the airborne sound insulation for a given % frequency only depends on the weight of the panel per unit area. The sound insulation R increases with each doubling of the frequency by an increment of 6 dB, according to the formula

20 log Ms + 20 log f - 49 dB20 log M s + 20 log f - 49 dB

Dabei ist mit f die Frequenz in Hz und mit Mg das Gewicht pro Flächeneinheit in kg/m bezeichnet. .The frequency in Hz is designated by f and the weight per unit area in kg / m 2 by M g. .

Die Anforderungen an die Schalldämmung werden im allgemeinen durch die erforderliche Schalldämmung für die niedrigsten Frequenzen bestimmt. Bei den höheren Frequenzen erhält man dann eine unnötig gute Schalldämmung. Bei Platten oder Scheiben mit einer Dicke über 4 mm ist die Schalldämmung in dem vorstehend angegebenen Frequenzbereich auch von der Steifheit der Platte abhängig. Im Bereich der Koinzidenzfrequenz f ist die Schalldämmung geringer als nach der vorstehend angegebenen Formel. Die Koinzidenzfrequenz der Platte wird nach der FormelThe requirements for sound insulation are generally determined by the sound insulation required for the the lowest frequencies. At the higher frequencies, you get an unnecessarily good sound insulation. With plates or panes with a thickness of more than 4 mm, the sound insulation in the frequency range specified above is also of the Plate stiffness dependent. In the area of the coincidence frequency f, the sound insulation is lower than after the above given formula. The coincidence frequency of the plate is according to the formula

f = 1,83 . IQ4
σf = 1.83. IQ 4

heit in kg/m und B die Biegesteifigkeit der Platte pro Einheit der Breite in Nm (Newton meter) bezeichnet.is the bending stiffness of the panel per unit in kg / m and B the width in Nm (Newton meter).

Bei einer 6 mm dicken Platte liegt fc bei etwa 2500 Hz, d.h. etwas unterhalb der oberen Frequenz von 3150 Hz. Bei den Frequenzen im oberen Teil des Normbereichs ist die Schalldämmung jedoch besser als vorgeschrieben, so daß die Herabsetzung der Schalldämmung im Bereich der Koinzidenzfrequenz zulässig ist.For a 6 mm thick plate, f c is around 2500 Hz, i.e. slightly below the upper frequency of 3150 Hz. At the frequencies in the upper part of the standard range, however, the sound insulation is better than prescribed, so that the reduction in the sound insulation in the range of the coincidence frequency is permissible.

Bei einer dickeren Platte mit einer Koinzidenzfrequenz unter 2500 Hz wird die Schalldämmung im Bereich der Koinzidenzfrequenz so stark herabgesetzt, daß sie nur geringeren Anforderungen genügt. Es hat daher den Anschein, daß man eine befriedigende Schalldämmung nur bis zu einer Plattendicke von 6 mm erzielen kann. Dies trifft jedoch nicht in allen Fällen zu.For a thicker plate with a coincidence frequency below 2500 Hz, the sound insulation in the area of the coincidence frequency is reduced so much that it only meets lower requirements enough. It therefore appears that a satisfactory sound insulation can only be obtained up to a panel thickness of 6 mm can achieve. However, this is not the case in all cases.

Nach der Formel (2) ist die Koinzidenzfrequenz des aus mehreren Glasscheiben gebildeten Verbundelements. nicht niedriger als die der dicksten Glasplatte des Elements, weil das Verhältnis Mg/B unverändert bleibt oder größer wird, wenn die Glasplatten nachgiebig miteinander verbunden sind.According to the formula (2) is the coincidence frequency of the composite element formed from a plurality of glass panes. not lower than that of the thickest glass plate of the element, because the ratio M g / B remains unchanged or becomes larger when the glass plates are flexibly connected to one another.

Aufgabe der Erfindung ist es, ein schalldämmendes Bauelement von guter Festigkeit und mit guter schalldämmender Wirkung zu schaffen.The object of the invention is to provide a sound-absorbing Construction element of good strength and with good soundproofing Create impact.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß einander gegenüberliegende Flächen voneinander benachbarter ^ Glasplatten in ihrem ganzen Ausmaß durch einen Film aus einem durchsichtigen Klebstoff mit hohen viskoselastischen Energie- φ Verlusten verbunden sind.According to the invention, this object is achieved in that opposing surfaces of mutually adjacent ^ Glass plates in their full extent through a film of one transparent adhesive with high visco-elastic energy- φ Losses are associated.

Der verwendete Klebstoff muß eine einwandfreie durchsichtige Zwischenschicht bilden und im Innern des aus den Glasscheiben gebildeten Verbundelements zu viskoselastischen Energieverlusten führen. Derartige Klebstoffe auf Kunststoffbasis sind im Handel erhältlich, beispielsweise das von den Farbwerken Höchst unter der Bezeichnung VP 71 vertriebene Vinyl-Acetat-Mischpolymerisat. Infolge der Innenverluste des Verbundelements wird die Herabsetzung der Schalldämmung an der Koinzidenzfrequenz kompensiert, so daß Glas in jeder be- \ liebigen Dicke verwendet werden kann. Die Möglichkeit, in dem j Bauelement Glasplatten jeder gewünschten Dicke zu verwenden, ^ gestattet die Herstellung von Bauelementen großer Festigkeit.The adhesive used must form a perfectly transparent intermediate layer and lead to viscoelastic energy losses in the interior of the composite element formed from the glass panes. Such plastic-based adhesives are commercially available, for example the vinyl acetate copolymer sold by Farbwerke Höchst under the name VP 71. As a result, the inner loss of the composite element, the reduction of the sound insulation is compensated at the coincidence frequency, so that glass can be used in any loading \ arbitrary thickness. The possibility of using glass plates of any desired thickness in the structural element allows the production of structural elements of great strength.
