Description

The invention relates to a noise barrier, with a formed from grid mats, with a fillable with noise filling material filling space.

Such noise barriers usually consist of stacked and side by side, so-called. Gabionenkörben, as for example from the DE 200 15 661.6 U1 are known. They serve in particular in residential areas of the insulation of traffic noise, emanating from busy motor vehicle roads.

From the DE 199 38 676 Furthermore, a soundproof wall is known in which a plurality of soundproofing plates are used in struts and can be held by a foundation. Although such soundproof walls are quite stable and can be held against wind attacks by guy ropes, but they are quite unsightly and are generally perceived as a disruptive factor in a landscape.

Since these noise barriers not only cause good soundproofing, but also should have a most aesthetically pleasing appearance, is from the DE 94 08 184.0 U1 a known consisting of grid mats truncated pyramidal soundproof wall, which is filled with a filling material. On this wall body mats can be placed and provided with plantings. Such plantings, however, are rooted only on these mats or in the filling material and, in addition to the high space requirement, also require intensive care. The care of such soundproof walls is thus relatively high and costly.

Furthermore, from the DE 698 07 049 a soundproof wall known, which consists of a variety of roof-sparing against each other supported pipes. These tubes are provided with an irregular fiber covering, on which plants are to grow up. These plants can be planted in the ground in front of the wall. The maintenance of such soundproof walls is indeed lower compared to the foregoing, but the space required by the design is relatively high and the production requires considerable effort.

Object of the present invention is to provide a soundproof wall of the type described above, which requires a small footprint for their installation, which can be easily manufactured and with simple means an optically aesthetic design of their visible surface.

This object is achieved by the features of claim 1, in particular by the fact that both sides of the fillable with noise filling filler filling space inner mesh mats are provided to which run to form joint-free mating spaces joint-free outer grid mats.

Through these measures, a joint-free, quasi monolithic appearing noise barrier is created, the outer visible surfaces can be designed with an aesthetically pleasing appearance. The outer visible surfaces can be made differently homogeneous or inhomogeneous in color.

According to an advantageous embodiment of the invention, the central filling space and the auxiliary spaces are free of joints over their entire length and height. The length and height of the visible surfaces are therefore variable and can be adapted to the respective landscape conditions and freely chosen. Commercially available sanded gabion baskets can not do this because they have fixed dimensions. They also have butt joints and joint crosses through which traffic noise can continue to penetrate.

Since there are relatively large filling spaces for the different filling materials, the filling process can easily be carried out by machine, for example by means of bucket-type excavators. The time and cost of installation and filling can be significantly reduced. Likewise, any health hazards to the staff on site and the environment, for example, by dust emission, largely avoided, but at least to a minimum.

Further, according to the invention, different uniformly or non-uniformly colored materials can be filled into the different outer facing spaces according to the invention.

The visible outer visible surfaces can be made so variable and artistic.

Further advantageous measures are described in the subclaims. The invention is illustrated in the accompanying drawings and will be described in more detail below.

The single FIGURE shows an isometric schematic representation of the section through a noise barrier according to the invention, with a central jointless filling space, with both sides inner grid mats and arranged at a predeterminable distance to outer grid mats, between which intentional spaces are formed.

The noise barrier shown in the figure 10 consists essentially of a seamless central filling space 11 that with a central filler 12 is filled. Usually, as a central filler 12 Sand or a different fine-grained bodied material used.

The central filling room 11 is by both sides arranged jointless inner mesh mats 13 and 13a educated. At a predetermined distance 14 in front of the seamless inner mesh mats 13 and 13a are also jointless outer mesh mats 15 and 15a appropriate. Between the inner mesh mats 13 and 13a and the outer mesh mats 15 and 15a arise on both sides of the central filling space 11 jointless additional space 16 and 16a made with a preferably monolithic filler material 17 can be filled.

As filler 17 for the purpose rooms 16 and 16a Natural stone ballast, foam glass ballast, brick crushed stone, broken glass, concrete ballast or similar recycled material can be used.

The filling material 17 may have a uniform or different coloration. In an advantageous embodiment of the invention, the filler material 17 the intentional rooms 16 and 16a from natural stone gravel of the same or different colors.

The outer visible surfaces 18 the outer intentional spaces 16 and or 16a can with different colorations of the outer filler 17 be artistically designed differently. Thus, according to the invention, adjacent adjoining spaces 16 and 16a filling materials 17 be filled, one of the visible surface 18 to visible surface 18 show a different color.

In another embodiment, it may be provided according to the invention, an outer filling space 16 and or 16a with mixtures of filling material 17 to fill with different colors. By these measures can of visible surface 18 to visible surface 18 another colorful outside picture is generated. Monotonous, sometimes boring noise barriers 10 will be lightened by these measures. The monotony-caused inattention of passing road users is thereby counteracted and reduces the risk of accidents.
