Description

ι · a a β ·

The invention relates to a kit for creation of noise barriers.

Noise barriers are known from the prior art, which

consist of concrete slabs set in vertical supports on which, seen in the direction of the noise emitters, Mineral fiber tubes and perforated bricks arranged on top of them

ί are.

It has been shown that especially in places that are exposed to strong wind gusts, these Noise barriers of the prior art only have sufficient static strength if both the supports and the foundations are extremely stable and therefore designed to be costly.

In contrast, the present invention is based on the object of providing a pillarless noise protection wall of the initially introduced called genus to create that also strong gusts of wind

c is absolutely stable with respect to, whereby also under way

In the case of expensive supports, it is possible to save on foundations. Another subtask of the present The invention is based on creating an optical range of variation that, for example Noise barriers erected on the edges of the motorway creates greater visual acceptance; another subtask consists in creating such noise barriers that are easy to dismantle, as do such noise barriers are desired to an ever increasing extent and two especially in those cases where -sine great noise nuisance is only a passing phenomenon.

Ultimately, such a noise protection wall is to be created that allows the creation of plantable spaces, which can cover a large part of the wall both inside and outside with vegetation «

This object on which the present invention is based is achieved in that a kit of individual noise barriers is created, which can be set up with one another in a kind of zigzag arrangement via joints.

This object is achieved in a kit of the type mentioned in that the individual kit elements from There are noise protection wall elements that have rear panels on which the layers of insulation are arranged in turn are covered with perforated plates, at least one side end of the rear plates being articulated Has training with a hinge axis, which is designed to work together with the neighboring plate.

The absorbing wall side consists preferably of ground, frost-proof and de-icing salt-resistant perforated bricks, wherein, according to a further preferred embodiment, the perforation obliquely downwards and is directed outside. As a result, the deposited mineral fiber mat in particular will be easier to keep dry because the rainwater drains safely and quickly through the inclined perforation. Furthermore, the wall is self-cleaning from the rain.

The wall according to the invention is highly absorbent and, according to a preferred embodiment, has a very low sound transmission ^{due to its high weight of more than 250 kg / m 2.}

According to a further preferred embodiment, there are the individual wall parts and the connecting parts of the individual Walls, which as a whole represent the kit according to the invention, made of maintenance-free .Material, .so. That no maintenance costs in purchase taken; we * Qde.n * pi $ §ei} < · * ":

The rear panels can optionally also consist of single panel elements.

The perforated panels are connected to the rear panel, for example by means of construction adhesive, after the Insulation layers are used.

The essence of the present invention will now be based on the accompanying Figures 1 to 5, the preferred embodiments represent, further explained.

The same elements are identified by the same reference symbols in the different figures.

Figure 1 shows a perspective view of an inventive Kit consisting of the three units I, II and III; each of these units is hiring Bausats element for the production of noise barriers The elements I and III are shown broken off.

With the reference number 1 is the rear concrete slab, with the reference number 2 is the insulation mat and the reference number 3 denotes the perforated brick. With the reference number 4 is that in the neighboring Lateral end areas of two concrete slabs arranged Joint referred to; the joint axis bears the reference number 5-

The hinge-like design of the joints of two adjacent concrete slabs is made up of this Figure 1 clearly visible. For example, the kit element II has at its left lateral end the two articular processes A and B and the incisions C and D, while the kit element I on his the side end facing the kit element II has a mirror image of the corresponding arrangement, where in the incision C of the element II the extension E of the element I and in the cut D of the element H '' 'k' ELfemts I engages.

Figure 2 shows a vertical section through the kit according to the invention or through a 3ausatzelernent. The common concrete slab is again denoted by the reference number 1, the insulating material mat consisting, for example, of mineral fiber mats with the reference number 2, and the perforated brick with the reference number 3. With the reference numeral 6, the foundation is indicated as an alternative _; that is not part of the kit according to the invention. The kit element or the individual elements of the kit that can be connected in a hinge-like manner by means of the joints can optionally be connected to a foundation 6.

Figure 3 shows a front view of the kit elements I, II, III and IV, with the kit elements I and IV broken off are drawn.

The reference symbol H denotes the joint and the reference symbol 5 denotes the steering axis as well as the reference symbols which, viewed from the noise source side, are identified on top of perforated brick arranged. The foundation is again identified with the reference numeral 6 for orientation. FIG. 3 thus shows a front view of four parts of the kit connected to one another via the joints, viewed from the noise source, for example from a motorway.

Figure 4 shows a plan view of elements I, II, III and IV in accordance with FIG. 3 in a slightly oppositely angled, that is to say in a zigzag-shaped arrangement.

FIG. 5 again shows a strongly angled arrangement of the five kit elements I, II, III, IV and V when viewed from above in opposite directions, i.e. in a zigzag arrangement. According to this exemplary embodiment of the arrangement of the kit according to the invention, the Angle between two kit elements each 90 °.
