Element for a noise barrier

809849/0121

-A-

The invention relates to an element for a noise protection wall.

There are already noise protection fences and noise and noise protection walls known in different embodiments, which, however, require either a considerable structural effort or a lengthy and complicated assembly. If these elements are made of concrete, they also have a relatively large weight, so that they can only be assembled with hoists.

Such noise barriers are used in particular on traffic routes, in the area of airfields or at noisy construction sites erected and must therefore generally have a height of several meters to protect the residents against the emerging To protect against noise; this in turn requires that the individual elements are sufficiently stable so that they in particular which can absorb wind forces, and in addition also resistant to external influences, in particular Humidity and fluctuating temperatures. These conditions are not sufficient by the conventional elements Fulfilled to some extent.

The invention is therefore based on the object of an element f '"T to create a noise barrier of the specified type, both of the disadvantages mentioned above do not occur.

In particular, an element should be proposed that on the one hand Due to its special shape, it has a high level of strength and, on the other hand, is stable without foundations and supports can be installed in the ground.

This is inventively achieved by a group consisting of a triangular base and two thin side walls molded body of glass fiber reinforced concrete.

The advantages achieved by the invention are based in particular It is important that these elements are produced easily and thus inexpensively, without great effort and if necessary can even be transported by hand and assembled in a simple manner, with no additional Foundations result in a very stable construction that can withstand the wind loads that occur. Also is the material used is corrosion-resistant and non-flammable, making these elements both suitable for use on roads as well as for use in the vicinity of high temperatures, for example in airport hangars, are suitable. This material is also very resistant to the effects of the weather.

It is particularly noticeable that glass fiber concrete can be processed with very thin walls, so that there are particularly light elements. Nevertheless, these elements have sufficient strength as the thin side walls with the bottom have a pyramid shape and the surfaces running upwards twist like a propeller are; the vertical edges provided on both sides, which are used to fasten the elements in a row serve, run straight and perpendicular.

So that the noise barrier has sufficient stability has, the individual elements are lined up in a zigzag shape and depending on their height correspondingly deep buried in the ground.

Because the lower end of each element is closed in a triangular shape is, the soil acts as a load when refilling, which significantly increases the stability.

809849/0121

However, the elements do not have to be zigzag, but rather can also be arranged on the same side.

When assembling, a v / calibrated material inserted to avoid material inaccuracies equalize and avoid clamping stresses. The merger takes place frictionally by means of screws, nuts and washers, which are also made of soft material are highlighted. As a quality material, it is more convenient Rubber and / or plastic used.

mach DIN) Instead of nuts, Ringmutxern / vervvenciet be used for hanging absorbent components or vcn Serve vegetation grids.

In addition to increasing stability, the twisted triangular cross-section still has the advantage that assembly inaccuracies can not be detected with the eye and do not appear disadvantageous in any other way.

Due to the inclined surfaces, there are special light and shadow effects that make the color design of the Approach the noise barrier. Such a viand is therefore particularly suitable for landscaping.

Technically sound results from the vertically inclined wall surfaces compared to vertical ones, which are cheaper Reflection angle for the sound beams. Even through the horizontal The zigzag arrangement of the elements causes a scattering of the sound energy, which is at the receiver, for example residents, as a noise reduction effect.

Since such a noise barrier can be assembled quickly and easily from simple elements, it can be inexpensive manufacture, possibly even in-house.

And finally it is due to the special shape of the elements stability is greatest at the point where the strongest Loads occur, that is, in the area of the transition from the restraint in the ground to the free-standing wall part.

In the following, the invention is based on exemplary embodiments with reference to the enclosed schematic Drawings explained in more detail.

Show it:

Fig. 1 is an interior view of an element for a noise protection wall according to the present invention;

Fig. 2 shows the element in a side view, clockwise by 90 ° displaced from the view according to FIG. 1;

Figure 3 is a plan view of the element;

Fiq. ti a section of a connection point between the individual elements, the elements being lined up according to the illustration in FIG.

The element shown in Figure 1 for a noise protection wall consists of a molded body 1 made of glass fiber concrete. This molded body 1 v / eist thin side walls 2 and 3 on which a code 7 is molded. The thin sides 2 and 3 are Inclined in a pyramid-like manner to one another, resulting in a common, inclined edge 5 (compare FIGS. 1 and 2).

At their outer edges go the thin side walls 2 or in flanges 4 or v /. 6 over, which is also made of fiberglass-reinforced concrete exist and run perpendicular to the bottom 7. In the

4 9/0121

Flanges 4 and 6 are provided with holes 9 through which a screw connection to the adjacent elements is made can be.

The thin side walls 2 and 3 form at the edge 5 to Interior of the element towards each other at an acute angle.

In FIG. 2, the element is shown in a side view which, compared to the interior view of FIG. 1, is 90 ° clockwise The vertical inclination of the thin Seitcnwändc 2 and 3 can be seen on the course the edge 5 and the perpendicular course of the flanges 6 and 4 to the floor 7 can be seen.

In the plan view according to FIG. 2, an element and part of an adjoining element can be seen. The connecting elements used for the connection are again shown in detail on an enlarged scale in FIG shown.

In Figure 3, the thin side walls 2 and 3 and the abutting edge 5 of the two side walls can be seen. The side wall 2 merges into the flange 4, while the flange 6 forms the end of the side wall 3. Is on the flange 6 on another flange 6 of an adjacent element, of which only the side wall 3 is shown.

This arrangement results in a zigzag shape of the individual elements, the center line of this juxtaposition through the bottoms 7 of the elements is formed.

However, it is also possible to arrange the elements on the same side. In this case, the flanges 4 and 6 composed. The triangular bottom 7 thus forms

809849/0121

each the underside of such an arrangement, that is, the side walls 2 and 3 each extend on the same side of the base 7.

In Figure 4, a section of a connection point between two elements is shown on an enlarged scale, a flange 6 of one element being joined together with a further flange 6 of the adjacent element. In addition, the respective thin side walls 3 are closed recognize. Between the flanges 6 is a soft material

10 arranged. Located on the outer surfaces of the flanges 6 A soft material 10 is also placed under washers 11 and 12.

Through the holes 9 in the flanges, the washers

11 and 12 and the soft material 10 extends a screw 13, which the two elements 1 via a nut 14 or a ring nut 15 connects to one another.

The thin side walls 2 and 3, the triangular bottom 7 and the flanges 4 and 6 can be coated with a protective coating or can be provided with a facade coating, for example to create a noise barrier in a landscape or to adapt to a building. In addition, such an element can also be used as a decorative wall or fence. Here, for example, ornamental elements can be fastened in the ring nuts 15, for example plant grids can be hung.

The soft material 10 can be rubber or foam plastic be used.

The elements are placed individually in a prepared trench and screwed together, so that any length of wall can be put together.

Dirt is then filled into niedreren layers under compression from both sides, whereby the side walls, in particular in the vicinity of the bottom, clamped and loaded so that ^ ina such noise barrier obtains the desired stability.

In the area of contact with the ground, the elements can be coated with a protective coating be provided against aggressive influences of the soil.
