ι Porm stones made of concrete with self-centering, V or Roof-shaped cross-section are known, for example, from DE-GM 75 2o o3o. The shaped stones explained there consist on the top and bottom of roof-shaped to each other, namely a blunt Angle enclosing storage areas. The heavy-weight dry retaining walls made from it are formed by layering the shaped stones on top of one another. Through a usually local

^ q concrete made foundation or by corresponding formed base stones will have a certain inclination corresponding to the static requirements Preset retaining wall. When the Pormsteine are installed in layers, they take a form-fitting manner Intervention stable position. The roof-shaped or V-shaped storage areas also have when laying a centering effect.

Due to the static regulations, the construction height of such retaining walls is for the protection of earth embankments limited. In order to be able to cover and secure embankments that are higher than the maximum ■! permissible overall height, it is known such Stutzig walls to be provided with anchor elements on the side facing the embankment or the earth Ip in the appropriate number and size in the ground

f are embedded. The production of such a

Retaining wall with earth anchors is relatively

f manoeuvrable, especially due to the installation of the under

30 circumstances elongated anchor elements.

The invention is therefore based on the object of a retaining wall or a kit for the creation of such To propose retaining walls that allow construction heights without the use of anchor elements are above the dimensions that are inherently permissible from a static point of view.

To solve this problem, the retaining wall according to the invention or a kit for the production of the same characterized in that the shaped stones with different dimensions transverse to the level of the retaining wall are formed, wherein the lower layers of Pormsteinen (support blocks) consist of larger dimensions.

A retaining wall designed in accordance with the invention accordingly has a stepped cross-section in the vertical Seen cutting plane. The retaining wall consists of at least two sections of different width or depth. The one formed in the lower area by the correspondingly dimensioned supporting blocks wider "step" leads to a corresponding

enlargement, namely widening of the support surface j

on the underground. The dimensions of the support i>

The approaches or extensions pointing to the Lvift side according to a further proposal of the invention, the shaped supporting blocks can be shaped in this way by appropriate cross-sectional design be that there are also mutually positive and / or centering interventions. Therefore it is preferable the approach of the support blocks is also roof-shaped or V-shaped with a very blunt TO angle formed.

The air-side end faces of the molded support blocks are based on a further proposal designed in the same way as the normal stones, so that in the front or top view the retaining wall optically does not differ between the normal shaped bricks and the supporting shaped bricks is recognizable.

Finally, the invention in the area of the transition from the support blocks to the normal blocks a special measure is taken, which consists in the fact that the upper support block through corresponding design forms a trough, trough or channel, which can be used as a plant trough to accommodate plants, Shrubs etc. is intended.

Further features of the invention relate to the design of the shaped stones and their arrangement. 30th

Fig. 1: 'A retaining wall made of normal stones and < Support stones in vertical section,

Fig. 2: an alternative embodiment of a

Retaining wall in a representation corresponding to FIG. 1,

Fig. J: a section of the retaining wall according to

Fig. 1 in side view and plan view.

The exemplary embodiments of retaining walls Io shown here serve to delimit one or both sides of earth embankments, e.g. B. earth dams and the like. The retaining walls Io consist of shaped stones made of concrete, the are arranged in layers one above the other. Two shaped stones with different shapes and sizes are installed in the embodiments shown.

The upper area of the retaining wall Io consists of normal shaped bricks 11. These have a certain shape, namely are angled in cross-section. It will be through it Formed on the top at an obtuse angle to each other facing bearing surfaces 15 and 16. Parallel to these are arranged accordingly on the underside, i.e. also at an obtuse angle to one another directed bearing surfaces 17 and 18 are formed. This roof or V-shaped arrangement of the bearing surfaces 15 ···· 18 the normal shaped bricks 11 can be laid with mutual self-centering.

In the illustrated embodiments, the earth

side, that is, the lower bearing surface 17 facing the slope is narrower in the direction transverse to the retaining wall Io dimensioned as the associated upper bearing surface 15 · The top of the normal shaped blocks 11 also points one adjacent to the air-side upper bearing surface 16, slightly upwards or into the horizontal angled edge surface 13 which is not covered by the normal shaped block 11 above. Through this arise on both sides of the retaining wall Io

stepped gradations 12 and 19. On the ground On the side facing it, this gradation 12 results in an intimate interlocking with the ground. on the air side of the retaining wall io are the horizontal ones Edges of the normal shaped blocks 11 at the front on the angled edge surface 13 and on the continuous The lower bearing surface 18 is each provided with a strong, noticeable bevel 2o and 21, respectively. An air-side end face 14 limited by this is in the laid state of the molded blocks directed essentially in the vertical plane or only slightly inclined out of this.

The slope of the retaining wall is Io in the present case determined by a foundation 22. In the exemplary embodiments shown, this consists of in-situ concrete. One upper foundation surface 23 corresponds with compliance an angle of inclination of the retaining wall Io of the surface of a lower shaped stone resting on it.

The retaining wall Io consists of the normal shaped stones 11 described and preferably several layers of shaped supporting stones 24. The latter form the lower part of the retaining wall Io. Such a shaped supporting block 2k rests on the foundation 22.

The shaped support stones have larger dimensions than in the direction transverse to the plane of the retaining wall Io the shaped stones. On the air side, a shoulder 25 widening the supporting molded block 24 closes at. Together with a head part 26, this forms the molded support block 24.

"" The head portion 26 is essentially the same geometrical features designed like the normal

Pormsteine 11. The latter can therefore be found in the area of the Transition to the support blocks 24 are built with these, in such a way that the features described -form-locking engagement, self-centering effect-

c are also given in this area.

The head part 26 is accordingly on the upper side by bearing surfaces directed at an acute angle to one another 27 and 28 limited. Parallel running and

^ Q in the same way arranged bearing surfaces 29 and are located on the underside of each head part 26. The side facing the embankment, i.e. the earth of the head part 26 is designed differently from the normal shaped blocks 11 in the present case

^ 5 namely from two rear surfaces 31 and 32 of unequal size arranged at an obtuse angle to one another. The shaped support blocks 2k built with one another thus form a sawtooth-shaped boundary surface on the side facing the earth. Alternatively, however, the head parts 26 can be designed like the normal shaped blocks 11 in this area. Conversely, it is possible and advantageous to form the normal shaped stones 11 on the side facing the ground like the head parts 26.

The elongated, plate-shaped extensions 25 adjoin the head part with an upwardly directed, inclined intermediate surface 33 on the top and bottom, namely on its bearing surfaces 28 and 3o. Accordingly, together with the intermediate surface 33, these form a recess 3 ¹ J with a triangular cross section or a corresponding elevation on the underside. These areas are mutually in positive engagement. In addition, the intermediate surface 33 is arranged and dimensioned in such a way that the lower bevel 21 of the lower normal shaped block 11 fits snugly against the intermediate surface 33.

-δι The other part of the approach 25 also forms the top and support surfaces 35, 36 (upper side) and 37, 38 which are directed towards one another in a roof-shaped or V-shaped manner on the underside (underside). These support surfaces, which are directed at a very obtuse angle to each other, create another toothing of the support blocks 24 with one another.

Air-side end faces 39 of the molded support blocks 24 or the projections 25 are optically designed in the same way like the end faces 14 of the normal shaped bricks 11. In this sense, the upper and lower edge are clear Chamfers 4o, 41 formed. The view of the retaining wall Io from the air side is therefore uniform, as there are visual differences between the areas of the Stüts- = shaped stones 24 and the normal shaped blocks 11 cannot be seen.

Normal molded blocks 11 and supporting molded blocks 24 are, as can be seen from FIG. 3, in layers 42 and 43 in the direction the retaining wall Io set. In the present embodiment if the normal shaped bricks 11 are arranged at a distance within the layers 42 of the same, see above that spaces 44 are formed. these can

Record plantings of shrubs, flowers, etc. 25th

In the present case, the shaped supporting blocks 24 have a smaller width (dimension in the plane of the supporting wall Io) designed as the normal shaped blocks 11.

This is intended to achieve an approximate equilibrium of the

both types of shaped stone can be achieved. As can also be seen from Fig. 3, the support blocks Io are in their layers 43 arranged in a sealing position, so without a gap.

Another special feature is shown in FIG. In the area of the transition from the layers 43 of the (wider) Support blocks 24 to normal blocks 11 is

by correspondingly designing the shaped supporting blocks 24a of the upper layer 43a of the same, an upwardly open tub-shaped container is formed, which is used here as a plant trough 45. For this purpose, the shaped supporting blocks 2 ¹ Ia are provided at the outermost edge with an upright or inclined web 46 made of concrete. This web 46 extends over the full width of the supporting shaped stone 24a, so that the continuous planting trough 45 is created when the same is laid without gaps. This is delimited on the inside by the end face 14a of the lower normal shaped block 11a.
