Abstract

Soundproof glazing unit has several thicknesses of transparent glass and plastic material, each thickness of plastic material being situated between and adhering to two thicknesses of glass, and the thickness of the plastic material being not less than the thickness of the thickest glass. Specif., the glazing unit consists of two thicknesses of glass and a single thickness of plastic material. The plastic material has a thickness >=5 mm, and is twice as thick as the thinner glass. The unit is produced by pouring a liquid resin between two glass layers and allowing this resin to harden, or by placing a sheet of plastic material between two glass layers and bonding to the glass with an adhesive. The liquid resin pref. consists of a mixt. of methyl methacrylate, polymethyl methacrylate and a redox catalyst system.

Description

Schalldämmende Scheibe Die Erfindung bezieht sich auf eine schalldämmende Scheibe mit mindestens zwei aussen liegenden Glastafeln und jeweils einer dazwischen liegenden, an den Glastafeln haftenden Kunststoffschicht. Sound absorbing disc The invention relates to a sound absorbing disc Disc with at least two external glass panels and one in between lying plastic layer adhering to the glass panels.

Derartige schalldämmende Scheiben sind aus der US-Patentschrift 3 546 064 und der Britischen Patentschrift 1 223 540 bekannt. GemäB diesem Stand der Technik werden zwei Glastafeln entweder durch eine zwischen sie eingegossene Schicht eines auslaufenden Kunststoffes von l bis 1,5 mm oder durch einen Klebstoffilm miteinander verbunden, Es hat sich gezeigt, daß die Schallisolation dieser so über eine Kunststoffschicht miteinander verbundenen Glastafeln nicht wesentlich größer ist, als bei gleichdicken, durch einen Luftzwischenrauni getrennten Glastafeln, Der Erfindung liegt die Aufgabe zugrunde, die Schalldämpfung derartiger Scheiben wesentlich zu erhöhen.Such sound-absorbing panes are known from US Pat. No. 3 546 064 and British Patent 1,223,540. According to this state of the Technique are two glass panels either through a layer cast between them a leaking plastic from 1 to 1.5 mm or by an adhesive film with each other connected, It has been shown that the sound insulation of this is so via a plastic layer interconnected glass panels is not significantly larger than with the same thickness, Glass panels separated by an air gap, the object of the invention is based on significantly increasing the sound attenuation of such panes.

Erfindungsgemäß geschieht dies dadurch, daß die Kunst stoffschicht mindestens etwa so dick ist wie die dickste Glastafel, Durch die Ausbildung der Kunststoffschicht als relativ dicke Verbindungsschicht zwischen den Glastafeln erreicht man infolge der Brechung der Schallwellen an den Übergangsstellen von Glas zu Kunststoff eine Brechung der Schallwellen, die dann über eine beträchtliche Länge die Kunststoffschicht zu durchlaufen haben, wo sie eine wesentliche Dämpfung erfahren, Sodann ergeben sich an den Übergängen von Glas zu Kunststoff und umgekehrt Reflektionen, die infolge einer Dicke der Kunststoffschicht mindestens in der Größenordnung der dicksten Glastafeln zu Indifferenzen und damit zu teilweisen Auslöschungen führen. Bei einer erprobten Ausführungsform mit zwei Glastafeln von je 4 mm Dicke und einer Eunststoffschicht von 6 mm Dicke ergab sich damit eine Dämpfung von 38 dodezi Bei.According to the invention this is done in that the plastic layer is at least about as thick as the thickest Glass panel, through the Formation of the plastic layer as a relatively thick connecting layer between the Glass panels are reached as a result of the refraction of the sound waves at the transition points from glass to plastic a refraction of the sound waves, which then over a considerable Length to go through the plastic layer, where there is substantial cushioning experienced, then arise at the transitions from glass to plastic and vice versa Reflections resulting from a thickness of the plastic layer at least of the order of magnitude of the thickest glass panels lead to indifference and thus to partial extinctions. In a tried and tested embodiment with two glass panels, each 4 mm thick and one A plastic layer with a thickness of 6 mm resulted in an attenuation of 38 dodezi.

Dies ist ein für schalldämmende Scheiben sehr guter Wert.This is a very good value for sound-absorbing panes.

Es hat sich ergeben, daß sich derartige Werte der Schalldämmung dann ergeben, wenn die Kunststoffschicht mindestens 5 mm dick ist. Sodann hat sich gezeigt, daß es keinen Sinn hat, die Glastafeln besonders dick auszubilden, da von ihnen offenbar kein besonders hoher Dämpfungsgrad allein ausgeht0 Aus diesem Grunde hat sich eine Pusfiihrungsform als besonders vorteilhaft herausgestellt, bei der die Kunststoffschicht etwa doppelt so dick ist wie die dUxinste Glastafel.It has been found that such values of sound insulation then result if the plastic layer is at least 5 mm thick. Then it was shown that there is no point in making the glass panels particularly thick because of them apparently no particularly high degree of attenuation is the result0 for this reason a push guide has been found to be particularly advantageous in which the The plastic layer is about twice as thick as the thickest glass sheet.

Weitere Einzelheiten ergeben sich aus den Unteransprüchen.Further details emerge from the subclaims.

In den Figuren sind Ausführungsbeispiele der Erfindung dargestellt, Es zeigen: Figo 1 einen Teil einer schalldämmenden Scheibe im Schnitt, Fig. 8. eine derartige schalldämmende Scheibe als Bestandteil eines Mehrscheibenisolierglases0 In der Fig. 1 ist eine schalldämmende Scheibe im Schnitt dargestellt, bestehend aus den beiden Glastafeln 1 und 2 und der dazwischen liegenden Kunststoffschicht 3. Wie ersichtlich, ist diese Kunststoffschicht 5 dicker als jede der beiden Glastafeln 1 und 2, die hier gleich stark ausgebildet sind, was jedoch nicht erforderlich ist. Am unteren Wnd der beiden Glastafeln 1 und 2 enthalten diese einen strangförmigen Abstandhalter 4 aus einem nachgiebigen 0taterial, zum Beispiel thermoplastischer Kunststoff. Der Abstandhalter 4 ist so entlang des Randes der dargestellten Scheibe gelegt, daß sich ein nur nach oben offener Zwischenraum zwischen den Glasplatten 1 und 2 ergibt, in den dann der Kunststoff in flüssiger Form eingefüllt wird. Nach dem Verfestiben bildet sich die Kunststoffschicht 3, die die beiden Glastafeln 1 und 2 fest miteinander verbindet, Der Abstandhswlter 4 kann nach der Ausfüllung zwischen den Glastafeln 1 und 2 in der gezeichneten Lage verbleiben, wo er vorteilhaft die Kunststoffschicht 5 gegen Einflüsse von aussen schützt.In the figures, exemplary embodiments of the invention are shown, They show: FIG. 1 a part of a sound-absorbing pane in section, FIG. 8 a Such a sound-absorbing pane as part of a multi-pane insulating glass In 1, a sound-absorbing disc is shown in section, consisting of the two glass panels 1 and 2 and the plastic layer 3 in between. As can be seen, this plastic layer 5 is thicker than either of the two glass panels 1 and 2, which are equally strong here, but this is not necessary. On the lower wall of the two glass panels 1 and 2, these contain a strand-shaped one Spacer 4 made of a resilient 0taterial, for example thermoplastic Plastic. The spacer 4 is along the edge of the disk shown placed that there is only an upwardly open space between the glass plates 1 and 2 results, in which the plastic is then poured in liquid form. To the solidification forms the plastic layer 3, which the two glass panels 1 and 2 firmly connects to each other, the spacer 4 can after filling remain between the glass panels 1 and 2 in the position shown, where it is advantageous the plastic layer 5 protects against external influences.

ss-ist auch möglich, die Kunststoffrchicht 3 mit den Glastafeln 1 und 2 zu terkleben.ss- is also possible, the plastic layer 3 with the glass panels 1 and 2 to stick.
