FIELD OF THE INVENTION The present invention relates to a field element for noise protection of roadways and industrial plants, which is formed of grids of horizontal and vertical wires, which are filled with earth, stone and other materials.

On highways, so-called noise barriers are built in residential areas as part of environmental efforts. The same is done in residential areas near industrial plants, which are protected by suitable protective walls against noise from industrial plants. The simplest form of such a protective wall is a ground wall of a sufficient height, which is set up parallel to the longitudinal axis of the road or noise interlacing. These earth walls are then often planted with plants. This provides additional sound attenuation. In addition, the roots of the plants make the earth's wall more solid. The disadvantage of such walls is that they have a wide base and therefore require a relatively wide lane along the roadway. The space needed for such walls, especially in residential areas, is not available at all. Therefore, a number of different constructions have been developed. All of these constructions are based, more or less, on the construction of substrate-walled constructions that form tank-like spaces at intervals. These spaces are then filled with earth and the entire wall is planted with plants. Such constructions can absorb the required forces at the proper height of the protective wall and are therefore very expensive to manufacture. Apart from that, it is not possible to prevent the soil from drying out in relatively small tanks, especially during the drier and warmer summer months. This causes the plants to die. Such elements are known from De-GM 77 157.1. Of the German Patent Office for Design Protection of the Federal Republic of Germany, DE-GM 7638 926.9 and ATPS 362 308. Patent from the Federal Republic of Germany.

In addition, an ecological noise barrier has recently been attempted. It is a wire-like structure in which compost consisting of garbage and clarified sludge is kept. This compost serves as a medium for the desired vegetation. The advantage of such a wall is that it also solves the problem of disposing of such compost. It is a disadvantage, however, that the height of such noise protection walls can only be small, about 2 m. Thus, their scope of application is limited. In addition, additional foundation work must be carried out to ensure that such a noise barrier wall is sufficiently stable against the occurring wind forces. It is also disadvantageous that such a noise barrier requires extra expensive transport, since compost is usually loaded at the factory. thus, the production costs are partly very high.

The object of the present invention is to provide a lightweight, lightweight, easy-to-mount and versatile space element that can be used to create an effective noise barrier.

This object is solved according to the invention. that the wire mesh or plastic lattice mesh is assembled into a polygonal top open grid basket and that the vertical wires and the horizontal wires at the edges are preferably formed so as to extend over two sides.

According to the present invention there is provided a field element for noise protection of motorways, industrial plants, which is formed of grids made of wires of horizontal and vertical distribution; which is filled with earth, stone or the like and is planted with plants such that the vertical wires of steel, metal wire or plastic lattice are stretched beyond the horizontal outer wires and the lattices are pivotally connected to each other in an open lattice basket, .

In a preferred embodiment, the lattice sets comprise additional stiffening diagonal wires connecting the vertical wires, as well as corner stiffening wires and swiveling clamps mounted on the vertical wires at the corners.

It is expedient to design the spatial element so that the lattice sections are short horizontal lattice wires covering the longitudinal vertical wires of the lattice.

It is possible to provide a design in which the short horizontal wire of the short side of the grid basket is formed in a manner that engages the articulated bottom.

Preferably, the lattice baskets are constructed from 50-150 mm x 70 mm grids.

Alternatively, the lattice baskets may have overhanging connecting rods suitable for joining on the side of the grid.

Alternatively, the construction may be performed by placing the short vertical wires of the grid on the inside of the grid basket after mounting and welding.

The spatial element may also be formed by mesh elements forming an outer surface of the lattice mesh, which are secured by sliding the horizontal wires to prevent slipping.

Due to its construction, the spacer element is easy to transport and easy to install at the site of the guard wall. The individual lattice baskets can be easily placed and stacked on top of each other after filling and slightly compacted. Thus, the lattice basket forms a skeleton insert which allows for the construction of a whole wall which is steep and thus requires little space. In addition, it will not cause damage if it is partially washed away by the first or other erosion action of the ground filled with a bottom and top open grid basket or only a top open grid basket. In fact, this ground is grasped and retained by the baskets on the underside and offset. In addition, practically the entire outer surface of the protective wall formed from the grid baskets of the present invention is suitable for insertion of plants and thus provides a solid protective roof which additionally stabilizes the protective wall. Moisture can easily enter the core of the grid baskets. This prevents the plants from drying out or destroying them. The vertical wires always extend beyond the horizontal wires, i.e. the extreme horizontal wires, so that a sufficient rigidity can be achieved by placing the lattice baskets on one another. The individual baskets can also be positioned vertically or offset relative to one another. Additional stiffening can be achieved by connecting the overlapping horizontal wires with staples or stiffeners2

EN 212 284 Β or alternatively by bending the overhanging wires to form an intense bond. Thus, many variations are obtained, and not only perfectly uniform barrier walls, but also protruding, recessed barrier walls can be created.

A further advantage, in addition to the favorable transport conditions and low production costs, is that the spacer element of the invention retains its connection to the natural earth layer, which allows the barrier to be supplied with water from below and to allow bacteria and animals such as worms to enter. Thus, the construction of the barrier wall provides a homogeneous whole which is fully integrated into the landscape image and structure.

The hinged joint of the space element allows the entire basket to be transported in a folded state. The grid basket thus takes up little space and can be quickly installed. All you have to do is remove the individual grids. Preferably, the grid basket can be prefabricated at the manufacturing plant and only a stiffener should be placed at its mounting site to prevent unintentional folding of each grid.

In order to stiffen the lattice basket of folded lattice grids, according to the invention, diagonal reinforcing wires are placed horizontally on the corners of the lattice basket and provided with meshes on the vertical wires. In this way the vertical wires are fastened. The vertical wires stabilize the grid basket after unfolding. to get the desired and necessary stiffness. The stiffness is also improved by stacking the individual baskets vertically and connecting them together. In addition, it is expedient to place interconnecting wires between the vertical wires of the grid at the place where the maximum load of the long-side grid is applied, apart from the diagonal stiffeners. This prevents bending of the longitudinal grids without much effort. In addition, the vertical wires can be placed at different positions in height.

The articulated lattice basket according to the invention is simply and expediently formed by bending the horizontal wires of the lattice basket forming the short sides of the lattice basket around the end vertical wires of the long sides forming the lattice basket. This design of the lattice ends is much simpler than assigning individual elements to the baskets. In this way, the articulated grid basket can be prepared in the factory so that they only need to be adjusted at the installation site. The advantage of this design is that precision work can be carried out in advance at the manufacturing plant with the necessary machinery and only the finishing work at the installation site is required. In addition, it is also possible in principle for each grid to be joined by separate elements, at least at some of the bonding sites.

The end of the bottom horizontal wire of the grid forming the short sides of the grid basket is bent downwardly underneath the wrist, so as to easily prevent the grid forming the short sides of the grid from shifting. This prevents shifting or slipping and stabilizes the arterial element.

Production costs can advantageously be kept within limits by using baskets of substantially the same size. Even with such a construction size, the protective wall designs are extremely varied, since the grid baskets can be arranged vertically on one another and offset relative to one another, and can also be rotated by 190 °. It seemed appropriate to combine 100 x 70 and 150 x 70 mm grids and 50 x 70 mm grids into lattice baskets.

These rectangular shapes allow for a domino-like arrangement in the vertical and horizontal directions, and in addition, the entire guard wall is preferably stable. In addition, it has proved advantageous to use two grid baskets of two sizes, i.e. two different lengths, since it is possible to place three grid baskets at right angles to a grid basket below them, which further increases the spatial variability.

The stacked grid baskets have connecting grooves on the vertical wires at the edges for easy connection, or these wires are formed so that they can be bent to a hook. After placing the lattice baskets on one another, for example, the ends of the vertical wires are bent over and connected to the lateral wires of the lattice baskets above and / or below to form a stable whole with each other and the ground to be loaded.

The stabilization of the spatial element is terminated at each grid baskets on the side, with connecting rods extending beyond the grid, to which they are connected to the connecting rod of the adjacent grid baskets or subsequently connected to the connecting elements thereon. In the simplest form, at the end of the link rods, fixing plates are formed, which are always fixed on the outer or inner grid of two adjacent lattice baskets, which predetermine the distance of the adjacent lattice baskets. In this way, lattice baskets which are spaced apart on the outer sides of the earth wall and in which the intermediate space is filled with earth may also be interconnected.

In a further embodiment of the invention, the lattice meshes consist of welded horizontal and vertical wires at the joints. The shorter vertical wires are preferably located on the inside of the grid basket after assembly. Such a wire mesh can be produced relatively cheaply with existing devices. In principle, this can be the same as a welded grid called a construction net. These grids are assembled into lattice baskets by cutting or bending the ends of the horizontal wires.

The erosion protection of the built-in wall panels according to the invention is enhanced, especially in countries where heavy rainfall or bad weather is expected to be enhanced by attaching erosion protection nets to the grids. Erosion screens are pinched onto vertical and / or horizontal rods. In this way, erosion can be purposefully prevented or diverted to areas that are beneficial to the strength of the entire protective wall.

EN 212 284 Β points. Simple bonding of erosion protection nets can be achieved by forming flaps on the vertical wires at their first point of connection with the horizontal wires. These flaps prevent it from rising. and the sliding of erosion protection nets hung on it. Erosion nets are equipped with hooks. Post-bending makes it difficult to slip or slip erosion protection nets.

The lattice baskets according to the invention can be used to form barrier walls of virtually any size. In addition, the lattice baskets can be used to reinforce slopes or to create space. Finally, it is also conceivable that these lattice baskets, especially when filled with soil, are used for humus formation. To empty such lattice baskets, it is desirable to releasably connect one of the lattice meshes to the adjacent lattice mesh so that the lattice basket can be emptied in a container-like manner.

In adjacent or closely spaced grid baskets, it is expedient to place clamps or wire rings that are pivotable on the vertical rods, preferably the vertical rods in the corners. These coupling clamps can also advantageously be used to connect the lattice nets of the assembled lattice basket for ease of transport. They are also intended to be used to connect grid baskets set up side by side and filled with earth or other material.

Figure 9 shows two stacked lattice baskets in offset arrangement.

It can be clearly seen in Fig. 1 that the sides of the protective element 1 of the spacer element are formed in a steep form from the assembled grid baskets 2, 3, 4. The lattice baskets 2, 3, 4 are filled with earth. It can be seen that the lattice baskets 2, 3, 4 form a frame structure which is advantageous for the masonry unit 1, since at the same time their interior space can be filled with the earth 5. The resulting outer wall is advantageous for vegetation 6. Depending on how the lattice baskets 2, 3, 4 are stacked, a stepped wall may be produced, optionally a steep wall.

The 2 or 3 or 4 grid baskets are longer, 8 grids and shorter. It consists of 9 grids. These grids 8, 9 consist of welded horizontal wires 10, 10 'and vertical wires 11, 12, 13.

The horizontal wires 10 of the grid 9 are formed at their ends as curves 14, 15. These curves 14, 15 may advantageously be formed by bending the horizontal wires 10 inward. Thus, the hinge 23 forms a hinge 24 in a simple manner.

The corners 23 are additionally stabilized by diagonal reinforcing wires 16. The diagonal reinforcing wires 16 are located at opposite corners 23, 23 ', but can be arranged at all four corners. The diagonal reinforcing wires 16 are pulled on or attached to the vertical wires 11, 12, 13, and are thus placed in the production site with little effort. It is conceivable that the diagonal reinforcing wires 16 are fastened at one of their ends and shipped with the grid and then mounted as a diagonal reinforcement once the grid basket 2, 3, 4 is set up. To prevent bending of the grid 8 forming the longitudinal sides of the grid bases 2, 3, 4, a connecting wire 17 is used, which is shown in Figs.

Figures 4 and 5 - simply hooked into horizontal connecting wires.

Figure 2 shows the lattice basket 2, 3, 4 in the open state and Figure 3 in the closed state. Where the lattice mesh 8 lies snugly over the lattice mesh 8 ', or the lattice meshes 8, 9 are closely spaced.

Figure 4 is a side view of the grid basket 2, 3, 4. It follows that the diagonal reinforcing wires 16 lie on the edge of the horizontal wire 19.

The end of the respective lowest horizontal wire 25, as shown in Figure 5, is bent. The hinge 24 thus formed is below the extreme horizontal wire 20, while each of the hinges 24 abuts the horizontal wires 10, 10 '. In this way, the displacement of the grid 9 in the grid 8 is simply prevented. This also stabilizes and secures the edge 21 of the mesh 8, 9 in a simple manner. The joint 24 formed between the lattice grids 8, 9 is enlarged in Figure 6. The horizontal wires 10 and 10 'are bent here to encompass the outer vertical wire 13 to form the hinge 24.

The lattice baskets 2, 3, 4 can be assembled in a versatile manner to form a protective wall for a space element 1, as shown in Figure 7. To create the space element 1, first place the base lattice baskets 2, 3, 4 in relation to these and at the same time place two lattice baskets 2, 3, 4 at right angles to the axis of the protective element of the space element 1, resulting in a triple cube. They are then placed with a further 2, 3, 4 baskets at right angles to the lattice baskets 2, 3, 4 below, followed by another cube and finally a first series of lattice baskets of the longitudinal axis of the guard 1. Figure 1 shows a fully assembled barrier wall before land application or filling. The design is advantageous, for example, when the protective wall of the space element 1 is made entirely of sand and only then is applied to it as a barrier layer. The sand penetrates through the structure formed by the grid bases 2, 3, 4 and allows the formation of the barrier shown in Figure 1, which is then filled or sealed with earth and finally planted with vegetation. For further stabilization, the connecting rods 32, 33, which are already shown in Figure 1, are used.

Fig. 1 shows a wall protecting the space element 1, which consists of different grids 2, 3, 4 and into which ground grids 5 are placed. A 8, 9, 8 ',

9 'of the inner side 29 of the lattice mesh 30 are anti-erosion elements

EN 212 284 Β to prevent erosion. These anti-erosion elements preferably have eyes that are simply pulled over the protruding ends of the vertical wires 11, 12, 13.

While the spaced grid bases 2, 3, 4 are connected by means of the connecting rods 32, 33 as illustrated, the tightly adjacent grid bases 2, 3, 4 are joined by the clamps 34 shown in FIG. The embodiment of Fig. 3 shows that these coupling clips 34 are also suitable for securing transported lattice baskets 2, 3, 4.

Figures 8 and 9 show the possibility of placing the grid baskets 2, 3, 4 together or stacking them. Fig. 8 is a vertical assembly and Fig. 9 shows a vertical displacement assembly. As the lattice baskets 2, 3, 4 are open upwards and downwards, the ground can always be filled in the desired shape to obtain a protective wall element 1. The connection points of the horizontal wire 10 and the vertical wires 11, 12, 13, 27, 28 are welding points, thus forming a stable wire grid. Suitable wire cloth may also be used and the outer wires may form the fabric backbone, both vertically and horizontally. Figures 8 and 9 show stacked assemblies in the vertical direction in Figure 9. As the lattice baskets 2, 3, 4 are also open upwards here, the ground can always be filled in the desired form to obtain a protective wall of a stable space element 1. The bonding points 27, 28 of the horizontal wire 10 and the vertical wires 11, 12, 13 are welding points, thereby forming a stable wire grid. Suitable wire fabric can also be used, and the outer wires can then form both the vertical and horizontal strands of the fabric. 8 and 9, the hooks 31 connecting the respective lower two lattice baskets are bent or already formed in this way. Figure 8 illustrates that a stable lattice frame can be formed in this manner, which is then filled with earth in a known manner.

Of particular importance is the fact that a spacious element can be provided which can be used in a variety of ways for both noise barriers and other purposes. An important feature of spatial elements is its extremely affordable price, not least its ease of transport and ease of installation. The builder of such a wall has the possibility to optimally adapt the barrier to the existing conditions without major construction work. This fitting applies to both the height of the guard wall and the joint shape. It is also possible to form an offset wall by placing the grid baskets vertically on top of each other. In each case, a large open surface is provided for planting, which is also stable and advantageously adheres to the subsoil, resulting in a completely homogeneous system. The desiccation of the seed needed for vegetation is also made difficult by the connection to the soil that it can be considered excluded.
