Description
Es ist bekannt, daß normal ausgeführte leichte Wände eine ungenügende Schalldämmung aufweisen. Zur Verbesserung der Schalldämmung bei leichten Wänden sind bisher zwei Wege beschritten worden.It is known that normally designed light walls are insufficient Have sound insulation. To improve the sound insulation of light walls two paths have been taken so far.
Erster Weg: Die Wand wird doppelschalig - mit einem Luftzwischenraum - ausgeführt, wodurch die Dämmung bei geeigneter Ausbildung . wesentlich verbessert wird. Voraussetzung für die günstige Wirkung ist jedoch, daß die beiden Schalen nicht durch irgendwelche Stege (Schallbrücken) miteinander verbunden sind. Jede Schale benötigt deshalb, sofern sie nicht selbsttragend ausgeführt werden kann, eine gesonderte Tragkonstruktion, z. B. in Form eines Holzfachwerkes. Dadurch wird eine derartige Doppelwand verhältnismäßig teuer.First way: The wall becomes double-skinned - with an air gap - executed, whereby the insulation with suitable training. much improved will. A prerequisite for the beneficial effect, however, is that the two shells are not connected by any bridges (sound bridges). Every Therefore, if the shell cannot be designed to be self-supporting, a separate supporting structure, e.g. B. in the form of a wooden framework. This will such a double wall is relatively expensive.
Zweiter Weg: Durch Untersuchungen von L. C r e.m er ist bekannt, daß die Schalldämmung von einschaligen Wänden durch Verringern ihrer Biegesteifigkeit erhöht werden kann. Die Biegesteife einer Wandplatte kann z. B. nach einem Vorschlag von L. C r e m e r durch Einsägen von Rillen herabgesetzt werden. Einschalige Wände geringer Biegesteifigkeit haben den offensichtlichen Nachteil, daß sie den statischen Beanspruchungen in einem Wohnhaus nicht genügen.Second way: Through research by L. C r e.m he is known that the sound insulation of single-leaf walls by reducing their flexural rigidity can be increased. The bending stiffness of a wall panel can, for. B. after a suggestion by L. C r e m e r can be reduced by sawing in grooves. Single-leaf walls low bending stiffness have the obvious disadvantage that they have the static Stresses in a residential building are not enough.
Aufgabe der Erfindung°ist es, eine zweischalige Platte zu schaffen, die zum Aufbau von Leichtwänden guter Schalldämmung geeignet ist. Die Lösung dieser Aufgabe ist eine weitere Ausbildung der durch das Hauptpatent geschützten Erfindung. Die Lösung besteht darin, daß mindestens eine der beiden Schalen innen mit einem Netz. tiefer Nuten versehen ist und die Schalen zur Bildung des Luftzwischenraumes lediglich durch an zwei einander gegenüberliegenden Rändern verlaufende Stege starr miteinander verbunden sind.The object of the invention ° is to create a double-shell panel, which is suitable for the construction of lightweight walls with good sound insulation. The solution to this The task is a further development of the invention protected by the main patent. The solution is that at least one of the two shells inside with a Network. deeper grooves is provided and the shells to form the air gap only rigid by webs running on two opposite edges are connected to each other.
Ein Ausführungsbeispiel der Effindung ist in der Zeichnung veranschaulicht. Im einzelnen zeigt Abb. i einen Wandquerschnitt, Abb. 2 den Querschnitt einer Wandplatte in vergrößertem Maßstab.An embodiment of the invention is illustrated in the drawing. In detail, Fig. I shows a wall cross-section, Fig. 2 shows the cross-section of a wall panel on an enlarged scale.
Abb. 3 den Schnitt nach der Linie A-A der Abb. 2, in kleinerem Maßstab.Fig. 3 shows the section along the line A-A of Fig. 2, on a smaller scale.
Die Wand wird aus einzelnen- rechteckigen Wandplatten 14 aufgebaut, die z. B. über einzelne Nuten 15 unter Benutzung eines Fugenbindemittels miteinander verbunden werden können. Die Wandplatte 14 selbst besteht aus zwei Schalen 2, die durch zwei an ihrem oberen und ihrem unteren Rande verlaufende Stege 3 und 4 miteinander starr so verbunden sind, daß ein Luftzwischenraum 5 zwischen den Schalen verbleibt. Beide Schalen :2 oder nur eine der beiden sind innen mit einem Netz sich kreuzender tiefer Nuten 7 versehen, die zwischen sich Teilkörper 6 von z. B. rechteckigem Querschnitt stehenlassen. Der Zwischenraum 5 kann Schallschluckstoff 8 enthalten. Der Werkstoff der Platte selbst kann Gips, Holz-, Poren- oder Schwerbeton sein, zur Erhöhung der Biegezugfestigkeit, gegebenenfalls mit Beimischung von Fasern anorganischer, tierischer oder pflanzlicher Herkunft.The wall is built up from individual rectangular wall panels 14, the z. B. each other via individual grooves 15 using a joint binder can be connected. The wall plate 14 itself consists of two shells 2, the by two webs 3 and 4 running along their upper and lower edges are rigidly connected so that an air gap 5 remains between the shells. Both shells: 2 or only one of the two are intersecting inside with a network deeper grooves 7 provided, which between them part body 6 of z. B. rectangular cross-section leave. The intermediate space 5 can contain sound-absorbing material 8. The material the plate itself can be plaster of paris, wood, porous or heavy concrete to increase the Flexural tensile strength, if necessary with the addition of inorganic, animal fibers or of vegetable origin.
Theoretische und experimentelle Untersuchungen zeigten, daß eine solche Wand sich trotz der starren Verbindung der Plattenschalen 2 über die Stege 3, 4 akustisch nahezu wie eine Doppelwand mit völlig getrennten Schalen verhält, wenn die Schalen in der oben geschilderten Weise ausgebildet sind.Theoretical and experimental studies have shown that such Walled despite the rigid connection of the plate shells 2 via the webs 3, 4 acoustically behaves almost like a double wall with completely separate shells, if the shells are designed in the manner described above.
Die durch Luftschall angeregten Biegeschwingungen der ersten Plattenschale werden zwar weitgehend auf die zweite Plattenschale übertragen. Die Schwingungsform der zweiten Schale wird jedoch durch die besondere Struktur der zweiten Schale so beeinflußt, daß nur eine geringfügige Schallabstrahlung erfolgt (sog. Absträhleffekt).The bending vibrations of the first plate shell caused by airborne sound are largely transferred to the second plate shell. The waveform the second shell, however, is so due to the special structure of the second shell influences that there is only a slight emission of sound (so-called radiation effect).
Der durch die Erfindung erreichbare technische Fortschritt besteht in einem wesentlich einfacheren und biegesteiferen Wandaufbau als bei eigentlichen Doppelwänden (Weg i) oder biegeweichen Einfachwänden (Weg 2). -Die schalltechnischen Eigenschaften sind jedoch bei gleichem Gewicht etwa dieselben.The technical progress achievable by the invention persists in a much simpler and more rigid wall structure than the actual one Double walls (path i) or flexible single walls (path 2). -The acoustical However, properties are about the same for the same weight.
Eine aus erfindungsgemäßen Platten aufgebaute Wand wirkt akustisch als doppelschalige Wand; sie hat jedoch vom bautechnischen Standpunkt aus die Vorzüge der einschaligen Wand. Infolge der Anordnung stabiler Stege und des doppelschaligen Aufbaus weist sie trotz der sich kreuzenden Nuten eine gute statische Biegesteifigkeit auf.A wall constructed from panels according to the invention has an acoustic effect as a double-shell wall; however, from a structural engineering point of view, it has the merits the single-shell wall. As a result of the arrangement of stable webs and the double-shell In spite of the intersecting grooves, it has good static flexural rigidity on.
