Embankment stone 1

The innovation relates to an embankment stone with a top surface and a floor surface parallel to it * in the form of a hollow body open on the top and bottom surface.

According to the German utility model 7 614 681 is already an embankment stone with a top surface and a parallel aodent pool in rorm tines on the top and Floor area more open. Hollow body became known, the one

easy, quick and safe fastening of even steep slopes and even by inexperienced personnel which has a water-regulating effect and which enables simple and varied planting.

After laying the well-known embankment stone, he will be with fcrde filled, whereby it is preferably kept in its dimensions so that it is still problem-free when empty ^ e can be handled.

for applying a second layer of stones to the already relocated first layer will be the familiar, forward

to store runoff water, as occurs, for example, after a downpour. Even if the storage capacity is exceeded, the protruding bulges prevent the formation of torrents and break rushing streams of water.

With the well-known embankment stone, it is also possible Follow changes of direction on the embankments. Because of the special shape of the well-known embankment stone with its front and back surfaces curved towards the outside and the flat side surfaces however, when laying the stones in a curved line, depending on how strong the curvature is, between the straight lines Side surfaces of neighboring stones, acute-angled gaps and niches, which enhance the overall aesthetic impression of the Fastening made up of known embankment stones interfere and, moreover, a settlement of the vegetation can make it difficult at these points.

The task of the innovation is to create an embankment stone of the type mentioned above, which can also be lined up in several rows in arbitrarily curved lines without gaps being formed between the side walls of the stones, and the embankment stone should also be easy, quick and safe to attach enable even steep embankments even by inexperienced personnel, have a water-regulating effect and enable simple and varied planting.

This object is achieved according to the invention by an embankment stone which has the shape of a cylindrical outer surface whose axis is perpendicular to the top and bottom surface of the stone and whose cylinder ManteT. surfaces have an indentation curved towards the inside of the stone.

Another advantageous embodiment of the innovation is the indentation curved towards the inside of the stone is formed as part of a cylindrical outer surface, the axis of which runs perpendicular to the top and bottom surfaces of the stone.

It is also advantageous that the indentation, which is curved towards the inside of the stone, and the cylindrical outer surface of the stone are formed with the same radius of curvature, such that the stone with its cylindrical side surface fits into the recess of a neighboring stone after laying.

With the help of the stone according to the innovation, it is possible to do this several to be laid in a curved line so that no gaps between the stones remain free. D "'3S is achieved in that the embankment stones are lined up in such a way that they each with their cylinder jacket rest against the matching arched, indentation of the respective neighboring stone. A change of direction To achieve within the Steiniage, it is only wrong to use the slope stone according to the innovation

to turn when laying so that its retraction in the? desired new direction. When the next stone is concerned, the stone layer beats this new one
Direction. When applying the next layer of p Stei- NEN on the already laid first layer which can Rieh- p directional changes in the same way, within this stone \ management performed v / ground. In this way the renewal of contemporary% stones is made ööschungsbefestigung j any direction change in the situation in ih ^ he whole height, as can occur for example in the hillside parallel installation to follow.

Like the well-known embankment stone, the embankment stone according to the innovation is also filled with earth after laying, then
they are so resilient due to their weight that
they no longer slip even in the context of the continuation of the fastening work, so that mortar is also superfluous.

ueiü applying a second layer of stones to the first layer that has already been laid will be the new ones

contribute to the fastening.

The design of the slope stone according to the innovation as a cylinder jacket with one curved towards the inside of the stone Retraction, the axis of which is perpendicular to the top and bottom surface, also has the advantage that the hollow stone can be manufactured in a block molding machine of the usual type, so that it is inexpensive and without special systems can be produced. It will thus be more economical Benefit that lies in the fact that a high weight proportion of an embankment fortification made of earth is not sufficient There is masonry, and furthermore that the embankment stone according to the innovation is laid by inexperienced people cannot be diminished by inexpensive manufacture.

The special design of the slope-jj according to the innovation steins also has the advantage that it is used as an embankment fortification can erect, which is divided by cylindrical projections. Iniolge the variety of these Uniform, pleasing forms, the erasure made from new-year-old stones conveys an aesthetic effect appealing, playful overall impression.

In principle, it is possible to use the embankment in accordance with the renewal! To close stone like a flower bowl on its underside, with only drainage openings provided could become. This has the advantage that an embankment fortification with embankment stones according to the invention already exists

can be created before listing the slope up to a certain height, each after laying a Location of embankment stones these are filled with soil. In the context of the present innovation, however, it is It is an advantage that the embankment stone in accordance with the innovation also is designed to be open on the bottom surface. Deep roots of the planting can therefore be particularly good when it is stepped Structure of the embankment stones penetrate these and take root in the embankment soil. Furthermore, behind the Fixing leaking water through the embankment stones open on both sides penetrate to the outside, so that the danger the backwashing of an embankment fortification when using the embankment stone according to the innovation almost is completely excluded. Otherwise it is used in the embankment located water also for irrigation of the Bepflan-Eung in the slope stone according to the innovation, so that for example after making and fixing a terrain incision, irrigation even in the dry season the fortification planting is usually not necessary should be.

The hollow stone, which is also open at the bottom, preferably forms a circular tube section with an arched one Confiscation in one place. It is thus also possible to remove the deletion stones according to the innovation from a pipe or where it is necessary to use an embankment stone of lower height, this simply by shortening a standard

to manufacture schungsstein. But it is also the other way around

• j possible, matching embankment stones each un-

■ to create different heights, for example in order to

to compensate for uneven surfaces. In addition, the innovation according to Embankment stone can also be laid with the underside upwards, which saves time Laying reduced to a remarkable extent =

The embankment stone according to the invention is particularly intended to be laid in the stepped structure in such a way that the stone of one layer is offset by half a stone width compared to that of the next layer. ^In order to facilitate laying, the edges of the upper and / or lower surface can therefore advantageously have overlays that match the stone of the next layer in such a way that it can be laid effortlessly at the place presented. It is also possible, and in special cases advantageous, to provide corresponding recesses on the supports, into which the next higher stone fits in such a way that it inevitably can only be laid in the right place.

The special shape of the embankment sttins according to the renewal moreover has the advantage that it enables the same to be conveniently stacked, since a stack of one on top of the other is stacked Stones can be attached to other piles in several positions, which simplifies storage and transport and be cheaper. Because the stacks can also be put together in such a way that one
