EP1199438A2 - Silencing arrangement for closable facade openings and sound-insulating window elements - Google Patents

Abstract

The soffit (4) of the aperture of the building is sound-proofed by integrating into or onto the soffit box-shaped or layered sound-proofing elements (1) in the form of perforated metal sheets and arranging them around all or part of the window-frame (5). The surfaces of the sound-proof elements at right angles to the window's plane and next to the closeable window casement are structured to absorb sound.

Description

The invention relates to a method for sound insulation closable facade openings and soundproofed too opening windows.

Closable facade openings, especially window elements have good insulation when closed against sound; the windows, which are often tilted, Swing or parallel opening windows are formed, opened, however, outside noises penetrate practically unhindered through the window opening.

The windows are often used as bottom hung windows or night vent windows trained on the one hand the entry of outside air to allow through the limited opening and at the same time limit excessive sound ingress. Special Sound insulation measures for sound insulation in bottom hung windows or night vent windows with only a limited opening window are not yet known.

The object of the invention is the partially open Dampen windows penetrating sound, and window elements, usually consisting of window reveal and Windows to provide, in some cases open state the penetrating sound is dampened.

The object of the invention is achieved by the method according to claim 1 and the window element consisting of tilting window and window reveal according to claim 7, solved. Further advantageous embodiments of the invention result from the following claims 2 to 6 and 8 respectively.

The method according to the invention achieves that the penetrating sound with the incoming air clearly is steamed.

Figur 1 ist ein schematischer Vertikalschnitt durch eine erfindungsgemäße Anordnung aus Kippfenster und Fensterlaibung;

Figur 2 stellt eine bevorzugte Ausführungsform der Ausführung nach Figur 1 dar;

Figur 3 ist eine teilweise schematische Aufsicht auf die erfindungsgemäße Anordnung aus Fenster, Schalldämmung und Laibung.

The invention is illustrated by the following figures:

Figure 1 is a schematic vertical section through an inventive arrangement of tilt window and window reveal;

Figure 2 shows a preferred embodiment of the embodiment of Figure 1;

FIG. 3 is a partially schematic top view of the arrangement according to the invention consisting of window, sound insulation and reveal.

According to FIG. 1, 4 is on the inner surface of the reveal a tilting window 5 (Figure 1a) or parallel opening window 5 (Figure 1b), the window opening in whole or in part all around, a layered or box-shaped sound absorbing Element 1 arranged.

In the simplest case, this can be a shift sufficient thickness of a sound absorbing material, such as for example open-cell foam, mineral fiber, Flies, open-pored reveal coating or combinations thereof act. This layer or coating is preferred surface-structured in a sound-absorbing manner known per se, for example by knobs, ridges or webs. The sound-absorbing or -damping elements can be without or with a cover, for example with a flow permeable Cover, preferably with perforated plate (perforated sheet) be formed, the elements and the cover together fitted or spaced apart are.

The sound-absorbing or -damping are preferred Elements in the reveal area of the opening direction of the window arranged.

However, the sound-absorbing elements 1 preferably exist made of box-shaped elements, which, again preferred, a soundproofing material 3 and one essentially rectangular plate 2 running to the window plane, preferably a Perforated sheet, having, between the soundproofing material 3 and the perforated plate 2, an air gap 6 is formed; this Air gap 6 can otherwise in a conventional manner be damped by absorption, throttling or reflection.

An embodiment modified from FIG. 1 FIG. 2 shows this. It is essentially rectangular to the window surface 2 the swivel path the upper edge of the frame of the window 5 arcuate adjusted so that the air supply practically exclusively through the damped air gap. Otherwise correspond the reference numerals those according to FIG. 1.

In Figure 3 is a schematic partial supervision to an embodiment of an arrangement according to the invention reproduced from reveal 4, damping 1 and window 5. The Reference numerals correspond to those according to the previous one Figures 1 and 2.

The sound-absorbing elements 1 can be in the reveal, attached to it or integrated into it his. It is also possible to use the elements 1 with appropriate To arrange the thickness of the frame of the window 5 on this outside and, according to the tilting path of the window, the reveal 5 to be arched.

The method according to the invention is particularly suitable for sound insulation of window elements in facades as a clamping element or as a window element in perforated facades.
