Soundproof window with double glazing

The invention relates to a sound-insulating window with double glazing.

Most of the noises that enter a building from the outside come through the window surfaces into the interior. In particularly noise-endangered Areas such as near airports, on busy roads and the like, measures must therefore be taken to reduce the incidence of sound, for example at Hospitals or the like. The passage of sound through windows is made up of various components together, of which a substantial proportion is the part that is passed through the glass surfaces of the window the sound waves are made to vibrate, is transmitted into the interior.

Form 20/5 2000 12.64

The aim of the invention is to create means with which the passage of sound through the glass surfaces of a window can be reduced.

This object is achieved according to the invention in that the inner disc to the outer disc at an angle is arranged.

You invention "is in the drawing on a wood-metal composite window "For example, FIG. 3 illustrates and in the following in detail with reference to the drawing "described.

Figure 1 shows schematically a window according to the invention seen from the inside;

Figure 2 is a section along the line II-II in Figure 1;

Figure 3 is a section along the line III-III in Figure 1;

FIG. M is an enlarged illustration of the section according to FIG.

The wing of the jmis shown in the drawing "^: ·: has a wooden frame 2 on the inside ui'_i eiiio-n Frame 4 made of metal profiles on the outside, the frame 4- preferably pivotable or otherwise is releasably attached to the wooden frame 2.

The profile of the frame 4 has an outer leg 6 which, together with an inner glass retaining strip, holds an insulating glass pane which is used in the usual way with permanently plastic putty or with rubber seals. The insulating glass pane ': 0 consists of different thickness in a known manner from two discs, namely an outer thick disc 12 and an inner thin disc 14. In the wood frame 2, another glass plate 16 is fixed, which is inclined with respect to the insulating glass pane 10 at an angle oO, which can be on the order of 3. In the exemplary embodiment, the upper end of the disk is inclined inward. Este can, however, be useful in other directions of inclination, for example with the upper end outwards. Then the sound waves are radiated upwards at an angle and can be absorbed by a sound-absorbing ceiling.

_ Zj. _

On the inside of the wooden frame 2 is used as a bracket the disc 16 a box-shaped metal profile 1c _.:.- arranged, which "can have a U-shaped cross-section, for example, as shown in the drawing, and here, together with the wooden frame 2, encloses a closed circumferential space 20. At the the side facing the disc, the profile is provided with a projecting leg 22, which is the actual System for the glass sheet 16 forms. This leg is accordingly over the scope of the frame the inclination of the disc 16 cut off, for example in such a way that the lower horizontal Frame part of the legs completely cut off and the upper horizontal part has a length that extends results from the inclination of the disc, while the leg on the upright profiles accordingly cut at an angle of <7C. The inner disc is embedded in a putty 24 and is held by wooden glass strips 26, which are also in their Width are dimensioned according to the inclination of the disc, held.

In the rooms 20 an insulating material is arranged, and the web 28 of the U-shaped profile 18 is provided with a perforation 30 with a large passage cross-section provided, through which the space between the panes 1O and Ί6 with the spaces 20 in communication stair ;.

Between the outer legs of the profile 18 and the glass retaining strip S a rubber seal 32 is disposed to k "o seal the space between the discs and the insulation against the frame 4.

The arrangement described is a very strong reduction in the passage of sound through the Reached disc surface of a composite wing. This effect is based in particular on the fact that the aie Outer disk 10 penetrating sound waves obliquely strike the inner disk, causing them reflected at the angle and diverted to the window reveal, in which the sound energy is transmitted through the Insulating material 20 is destroyed or weakened.

The inventive arrangement of the discs is at all common pen windows with double glazing possible, i.e. with so-called armored windows, wood composite windows, Wood-metal composite windows and also pure metal composite windows.
