description

The invention relates to a concrete ring for the formation of terraces and walls, the wall of which on the one hand to the outside and on the other hand to achieve a form-fitting connection to the next Concrete ring is curved inward.

In a known concrete ring of this type, the wall shows a circular shape, where they in is essentially curved outward. Unfortunately, only a small part is in a corresponding manner, i. H. curved inwards with the same radius. This allows concrete rings to be positively locked - in straight lines like also curved line - line up. - In another concrete ring of the same type, the found an approximately elliptical course with otherwise similar training.

For these and similar concrete rings it applies that they allow a stringing together with a composite effect.

It is known to use it to secure slopes and embankments like terraces by creating several rows in a stepped manner placed one above the other and filled with soil. A part of each row remains and every single concrete ring is free at the top. This remaining part can be used as a planting area and a water catchment area can be used, whereby such concrete rings can be used at the same time as architectural design

will mean. If, on the other hand, the known concrete rings are arranged vertically one above the other »um In particular, to form a noise or privacy screen, there are no plant or water catchment areas more and thus the possibility of greening and natural design is no longer available.

As a way out, it has already been suggested to hang planters on such walls. However, this is very expensive. So the planter bowls not only have to be additionally manufactured and with soil filled, but can also be attached and secured individually. - Also known is one made of precast concrete parts composite wall (see. DE-PS 28 19 894), with the help of at least three different precast concrete plant niches can be created. It is a so-called Space lattice construction. This has each

! JO has the disadvantage of an expensive production and Storage of the individual parts, a complicated handling as well as planning and a limited one Usability. As a rule, it can only be used to erect straight walls while additional special components are required to form corners and curves.

This is where the invention comes in. It has set itself the task of making a concrete ring of the aforementioned Kind of training in such a way that not only terraces but also walls are provided let form from planting and water catchment areas. This goal is to be achieved with just a single molded part will.

According to the proposal of the invention, this object can be achieved in a surprisingly simple manner by

-S-

that the wall, seen over the circumference, consists of four sections of equal length, xvelche are alternately curved outwards and inwards.

Unlike the known concrete rings with only one outwardly curved section and only one inwardly curved section, the outwardly curved section being substantial is larger than the inwardly curved section, the invention now looks to two outside and two inwardly curved sections, each of the same size, alternately. These Concrete rings can be strung together in a form-fitting manner, each twisted by about 90 relative to one another.

The form fit is so intense that it results in a considerably increased bonding effect. Such rows of concrete rings according to the invention can be used for slope stabilization in known Arrange and plant in steps one above the other, but also for one Erect privacy and noise protection perpendicular to the walls. In the latter case, the rows need each just to be offset by a concrete ring to create the desired planting and water catchment areas to obtain. The rows or walls can also be designed as desired, in particular take a curved course, be it to correspond to border or terrain conditions, be it to achieve a special design effect.

Thus, the concrete ring according to the invention becomes one Universally usable construction and design element. Its versatility is alone with achieved its new shape, whereas the manufacturing effort compared to known concrete rings remains the same. The handling for the processor (in

The sections are advantageously curved in a circular manner. - Last but not least, this allows you to

Wall 1 consists of two inwardly curved sections 1a and two outwardly curved sections
1b, which follow one another alternately. The sections 1a and 1b are circularly curved here, with the same outer radius of curvature R ₁ and the

have the same arc length L ₁ , as can be seen in particular from FIG. 6. The wall 1 also thickens towards the bottom, whereby, among other things, there is a wedge effect for the soil to be filled and this can better hold itself in the concrete ring. At the transition from one section to the other, the concrete ring has curves 2.

According to Figures 3 and 4 · there are floor closures on len concrete ring 3 formed, which extend from the outwardly curved sections Ib and at a distance from one another end up. They also form slopes 4 sloping towards the center of the floor.

Such embodiments can be produced, for example, with the following dimensions: Outside diameter about 66 cm, height about 30 cm. They are suitable for forming noise barriers up to a height of about 3 m.

Larger ones are more suitable for higher noise barriers Concrete rings, for example with an outside diameter of 110 to 120 cm. These appropriately have Reinforcing ribs, in particular a central web 5, as shown in FIG.

The material of the concrete ring depends on the static requirements or the desired ones Surface properties (e.g. structured for better Sound absorption) and can be either heavy or lightweight concrete.

Figure 7 shows how the concrete rings to one another are to be strung. To do this, they have to be rotated 90 about their longitudinal axis from one to the other and close to one another be set. They surround each other with their outwardly and inwardly curved sections 1a, Ib, respectively largely and form an optimal network. The concrete rings can be oriented so that their Center points lie on a curved line or

but on a straight line according to FIG. 7. Also in the latter case, that is to say in a straight line Wall, the result is a corrugated outer surface, which is particularly attractive. thanks to the special shape of the concrete rings according to the invention arise neither in one nor in that other case disturbing .Projections, gaps or the like on the outer surface.

According to Figure 8, two rows of concrete rings are placed on top of one another, as they are required to build a wall. The two rows are offset from one another by a concrete ring. The upper row can be recognized by the drawn out contours of the concrete rings, the lower row essentially by the contours drawn with dashed lines. Due to the special shape of the concrete rings and their arrangement, there is no complete coverage from row to row, rather vo_ remains. Row to row of planting areas 6 (= hatched areas) frri, via which water required for irrigation, including rain, can also be collected. These planting areas 6 result within a ¹ "row from one concrete ring to the next but one, namely on both sides of those concrete rings, with the planting areas sitting on gaps from row to row. This creates ideal conditions for sufficient greening, especially with hanging plants, as well as a largely natural one Creation of a supply of rainwater.

According to FIG. 9, a concrete ring has a uni-outside on the inside directed lines of curvature, which consist of equally long, assemble straight sections 1 and thus a polygon form.

According to FIG. 10, the lines of curvature also form a polygon again, but in contrast to the object according to FIG. 10, the polygon consists of straight sections 1 ^, I ₂ of different lengths, which follow one another in symmetrical alternation.

In the two latter embodiments are otherwise, at the transition from one section la, Ib to the other, instead of rounded areas, flattened areas 2a intended.
