DESCRIPTION Embankment stone

TECHNICAL AREA

The present invention relates to an embankment stone with a polygon-like outer contour. Embankment stones of this type are used to secure embankments that do not have to withstand excessive earth pressure. In addition to good stability when installed, the use of embankment stones of this type should also enable plants to be planted within the embankment and thus the embankment stones in order to create an attractive appearance. In addition, easy handling during installation should be guaranteed.

TECHNICAL AREA

Embankment stones are known that essentially have a U-shaped cross-section. Such stones are arranged next to each other and offset one above the other, whereby plants can be planted in the offset spaces between them. The connection between such U-stones is unsatisfactory, so that even small earth pressures lead to undesirable shifting of the embankment stones. In addition, the appearance of such embankments lined with U-stones is considered less attractive, at least during the time when the plants do not cover the stones.

DESCRIPTION OF THE INVENTION

The present invention is based on the technical problem or task of specifying an improved embankment structure compared to the above-mentioned state of the art, which allows for simple manufacture.

position, can be easily laid to form a stable embankment, allows planting and also has an attractive appearance.

The embankment stone according to the invention is given by the features of claim 1. Advantageous embodiments and further developments are the subject of the subclaims.

The embankment stone according to the invention is accordingly characterized in that the outer contour has a toothed structure in a predeterminable pattern, which is designed in such a way that the toothed structures of at least one adjacent embankment stone can be brought into engagement with the existing toothed structure at least in some areas, preferably along a polygon side.

The circumferential interlocking structure ensures a wide range of uses for the embankment stone according to the invention, in that an embankment enclosure can be adapted to almost any contour. At the same time, the interlocking interlocking structures of adjacent embankment stones ensure a relatively high level of stability, since the individual stones laid at the same level have a good shear bond.

A preferred design is characterized in that the outer contours of essentially point and/or axis-symmetrically opposing tooth contours within a stone are designed as a positive or corresponding negative structure. Such a structural design ensures that the usual slope enclosures can be created without any problems, whereby an optimal interlocking of the slope stones with one another in one layer can be ensured. The slope stone according to the invention preferably has a hollow profile cross-section, so that the respective cavity present within the stone

can be filled with soil and planted. In addition, such a stone has a weight that is convenient for the installer.

A visually appealing external appearance is achieved according to the invention in that the toothed structure has continuous grooves, whereby an improved appearance can be ensured compared to the known embankment stones, at least during the time in which the plants do not cover the respective embankment stones. In some cases it is desirable that the plants do not completely cover the embankment stones in order to be able to check the condition of the embankment border formed from the embankment stones at any time. In these cases the embankment stones are therefore always visible. In order to offer a visually appealing solution for these cases, the embankment stones according to the invention have also been developed for this case.

A preferred design in terms of practicality in daily use is characterized by the fact that the embankment stone is designed as an octagonal stone. The contour is preferably chosen so that two opposite polygon base sides of an embankment stone are longer than the remaining polygon sides. These polygon base sides can, for example, be laid parallel to the contour lines of the embankment to be enclosed, so that a relatively small number of embankment stones are required per unit length of the embankment, which reduces the amount of material required for embankment stones. Embankment stones of this type enable a diverse laying pattern to adapt to the respective terrain, especially in corner areas.

In practice, it has proven to be advantageous to make the polygon base sides essentially 20 to 30 cm, preferably 25 cm, long and the remaining polygon sides 5 to 15 cm, preferably 10 cm. This allows

—A—

Due to the geometry required in most cases for the slope enclosures, adaptable laying plans can be developed that meet the requirements that arise in practice. Stones with such dimensions are also practically suitable for laying because they are relatively light.

A particularly advantageous design of the embankment stone according to the invention, in which the grooves are designed in such a way that they have a clear width that increases towards the outside, ensures reliable installation in terms of the interlocking structures while at the same time being able to cope with rough installation work. The grid-like arrangement of the grooves creates "projections" within the respective outer contour, which have a cross-sectional width that decreases towards the outside and can therefore be easily brought into engagement with the respective opposing interlocking structure of the adjacent embankment stone during installation.

A particularly cost-effective design of the embankment stone according to the invention in terms of production, which also ensures high material strength and weather resistance, is characterized in that the embankment stone is designed as a concrete stone.

Further embodiments and advantages of the invention result from the features further listed in the claims and from the exemplary embodiments given below. The features of the claims can be combined with one another in any way, provided they are not obviously mutually exclusive.

WAYS TO CARRY OUT THE INVENTION

A slope stone 10 designed as a hollow profile cross-section has an octagonal outer contour 12. The slope stone is designed to be axially symmetrical to the axes of symmetry A and B, where the intersection point M of the axes A and B represents the point symmetry center. Axes symmetrical to the axis A are polygon base sides 14, to which the remaining polygon sides 16 are connected to form the octagonal shape. The polygon-like encircling outer contour 12 of the slope stone 10 has toothing structures 20 to 26, which are present all the way around and are formed by grid-like circumferential grooves 28, which have a clear width that increases from the inside to the outside.

The imaginary outer contour 12 is shown in Fig. 1 in dashed areas. The grooves 28 arranged in a grid pattern and running from top to bottom along the outer contour perpendicular to the circumferential direction form a toothing structure that looks like this. The polygon sides 14, 16, which are mirrored over the point symmetry center M and are opposite each other on the outside, each have a positive structure or negative structure. In Fig. 1, the positive structure is shown with the extended reference symbol ".1" and the associated, opposite negative structure is shown with the extended reference symbol ".2". The external toothing structure 20.1 of the polygon base side 14 arranged on the underside in Fig. 1 is designed in such a way that it can be used as a negative or positive image in the opposite side of the polygon base side 14 on the top side according to Fig. 1. The situation is similar with the remaining polygon sides 16 and their toothing structures are designated 22.1, 24.1, 26.1 and the opposite toothing structures are designated 22.2, 24.2, 26.2.

• By forming such positive or negative interlocking structures within the circumferential outer contour of an embankment stone according to the invention, laying patterns are easily made possible which, when laid, ensure a secure engagement of adjacent embankment stones and thus contribute to stability, and on the other hand provide a high degree of variability in order to adapt to the most diverse embankment conditions.

The embodiment shown is only one of the many possibilities that ensure a practical implementation of the embankment stone according to the invention. In addition to the octagonal shape shown, embodiments that have a structured outer circumference contour with a different polygon circumference with a toothed structure are also possible.

Furthermore, the gear structure is not limited to the gear structure shown in the exemplary embodiment. Gear structures with other dimensions and cross-sectional shapes can be used, whereby the dimensions and contour shapes can be determined by the respective manufacturing process.

In Figs. 3 and 4, laying patterns of the embankment stone according to the invention are shown schematically. Fig. 3 shows schematically a corner formation of an embankment with an angle of 90 degrees, whereby this laying pattern enables embankment inclinations with relatively high values. The stability and suitability for planting are guaranteed in every case.

The lowest layer of embankment stones is marked 30. The layer of embankment stones above is marked 32. The formation of the third layer is marked 34. .

In contrast to the installation plan shown in Fig. 3, the installation plan 4 is suitable for a corner solution of a slope, in which the slope of the slope can be chosen to be lower than the slope of the slope according to Fig. 3. The slope stones of the lowest layer are designated with 40. The second layer, which is partially supported on the first layer of slope stones 40, is marked with slope stones 42. The slope stones partially placed on the second layer bear the reference number 44.

From the schematic representation of the laying plans according to Fig. 3 or 4 it is clear that the embankment stones according to the invention can be adapted to the respective conditions without any problems, while at the same time ensuring good shear protection of the individual stones among each other by interlocking the interlocking structures of the adjacent stones and

the planting of an embankment surrounded by the embankment stones according to the invention can be ensured at any time.
