$ "Noise barrier"

The invention relates to a noise barrier for arrangement on streets and other traffic routes or places.

In order to reduce the spread of traffic noise through sound insulation, it is known to use soundproofing on roads To anchor walls in the ground, made of metal posts and held between them, mostly " metallic framed, sound-absorbing panels exist.

Such noise barriers are relatively expensive. and expensive. In addition, they require very high assembly costs and are certainly not maintenance-free. In addition, such monotonous noise protection

walls for both road users and the neighbors considerable psychological stress.

With the invention, a noise protection wall of the type described above is sought, both in production and assembly is simpler and cheaper than known embodiments and a high level of sound insulation guaranteed. However, the advantage of the small space requirement, as with known noise barriers, should largely be achieved remain.

The solution to this problem is characterized by the features disclosed in claim i.

In this way you get a noise protection wall with partial flanks, not just the ones previously placed Requirements are met, but with the

■ i ! Sudem, such a noise protection wall is maintenance-free

1 because the sound absorbing agents used namely the planting, which is constantly regenerating

2 Also with such a noise protection wall by the applied sound-absorbing means certainly not to fear psychological exposure.

A preferred design of the noise barrier

I draws claim 2.

ti On the one hand, this ensures such a high level of stability

I mean that in most cases an additional

I borrowed anchoring unnecessary.

I On the other hand, the more or less inclined

I th wall flanks the vegetation "and an irrigation

due to natural precipitation.

Further advantageous embodiments of the above-described Noise protection wall disclose claims 3-5

I with strongly increasing resp. sloping terrain is

it is advantageous to provide ground anchors on the frame.

Zap 7080/78

An extremely robust design of the noise protection wall that may be preferred under certain circumstances is claimed. 7th marked.

Uk to ensure a high level of sound insulation and sound absorption even in areas with little precipitation is it advantageous, the above-described noise protection wall on the corridor side an at least water-permeable tub assign.

The latter can easily be made from a plastic sheet be folded.

Another advantageous feature is characterized in claim 9.

An embodiment of the invention is shown in the drawing and is described in more detail below.

The drawing shows a perspective representation of part of a set up at a place of use Noise barrier.

This noise protection wall comprises a trapezoidal frame 1 and longitudinal tensioning wires 2 as well on the flanks and walls arranged on the corridor side 3 made of wire mesh composite structure with Earth 4 · is filled.

In the soil 4 · are at the top of the wall and on the planks, not shown, the walls 3

penetrating plants used. Both grasses and bushes are suitable for this, preferably in mixed arrangement.

Instead of the tension wires 2, rigid struts can also be provided as frame spacers.

The frames 1 are preferably made of galvanized or plastic-coated steel profiles with a higher profile Flexural strength produced,

The wire mesh is preferably also coated with plastic.

Instead of the soil 4 · other absorbent ones can also be used Fillers, such as peat and / or K unststoffgranulat are provided, preferably with fertilizers enriched '; are.

When using soil 4- as a filling, it is advisable to fill the framework and the vegetation to be carried out only at the place of installation.

If this noise protection wall cannot be connected to natural embankments at the front, there are also the frame end faces and braid-like or similar walls are closed.

In order to get cheap transport options, this noise barrier can also consist of several one behind the other be composed of shots to be arranged, including two

or several spaced apart and provided with braided or similar walls 3 Bahmen are combined to form a transpert unit.

It goes without saying that it is also within a transport unit the arrangement of partition walls is possible. The noise barrier is preferably in a channel-shaped manner Floor recess 5 used. The latter gives the noise barrier a high level of security without Ground anchors are required. In addition, the depression in the ground can cause 5 fciE- Ίβη vegetation on the noise protection wall Form a favorable water reservoir.

It is particularly advantageous if the frame spacing is large Provide tie rods which act directly on the side walls 3 and tension them in order to bulge to prevent the side walls. It is advantageous to attach the ends of the tie rods To attach trusses that are supported on the outside of the walls 3.

This noise barrier, which has the character of a hedge, can also be used as the delimitation of parcels will.
