Abstract

Retaining block (1) which has an essentially rectangular shape and is designed in the form of a frame. At its top end, the front wall (2) of the retaining block (1) has a uniform, round or oval, trough-shaped recess (7) which, starting from both side walls (3, 4) of the retaining block (1) at an acute angle (beta), enables the plant to grow unhindered.

Description

The invention relates to a slope element which enables the slope to be reinforced and grassed and is essentially formed by a rectangular frame-shaped body on the upper side of which a groove-like depression is formed.

BACKGROUND OF THE INVENTION

Elements of this kind are, inter alia, made of cast, for example, concrete mixtures, and serve to secure slopes.

In particular, they are used on steep walls for sloping slope walls, slopes, protective and walled rail walls.

Z rak. pat. No. 394 222 discloses a shaped element of the kind used for securing slopes on which both the front and the opposing rear walls have a shallow depression formed from above, which always passes into the upper surface of its side walls. Shaped elements of this kind serve well to secure slopes, but are not suitable for grassing.

Swiss patent 663,922 discloses slope elements whose side walls are concave in a horizontal direction, which makes it possible to form rounded systems thereof. However, their side walls are planarly terminated from above, so that their faces form vertical edges. A disadvantage of such front walls is that the growth of the plants on the contour parts is prevented, which does not allow their natural growth.

SUMMARY OF THE INVENTION

SUMMARY OF THE INVENTION It is an object of the present invention to provide slope elements which substantially eliminate these disadvantages and do not prevent the natural development of plants on the areas covered by them.

This object is achieved according to the invention by providing a slope element formed by a substantially rectangular frame-shaped body on the upper side of which a groove-like depression is formed.

It is the essence of the slope element according to the invention that the groove-like depression is formed at least on the front wall by a continuous curvature between the two side walls of the slope element so that it emerges from the side walls at an acute angle. The depression is preferably formed by a circular arc with a radius of curvature of 180 to 220 mm, preferably 210 mm, and its depth in the central part is 40 to 60 mm, preferably 50 mm.

It is also an object of the invention that the outer surface of the slope element is domed from above and that the inner surface of the front wall is inclined at an acute angle of 60 ° to 70 °, preferably 65 ° with respect to the horizontal, such that the front wall taperes upwards.

It is a further object of the invention that on the outer surface of the front wall of the slope element, a horizontally extending flattening or longitudinal elevation of the bar shape is preferably formed in the central zone, limited from below and from above by limiting surfaces, preferably parallel to each other. In this case, the entire width of the slope element, preferably from one side wall to the other side wall, is preferably provided by the longitudinal elevation and its front surface is substantially oriented vertically. Further, the longitudinal elevation is preferably raised only by its one surface, i.e. the upper surface or the lower surface, above the adjacent outer surface of the front wall, and the opposite surface extends smoothly into the outer surface of the front wall.

It is a further object of the invention that each of its lateral sides is provided at its upper edge with at least one recess which is preferably opposed to one another and at least one, preferably external, but preferably closed on both sides.

Finally, it is an object of the invention that a well recess is formed in the upper surface of the rear wall of the slope element.

When using a slope element according to the invention, the plant used for grassing areas provided with a system of such slope elements can develop naturally and produce a solid green slope without interruption on the contours of the slope elements used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT The element 1 is according to the base of FIG.

until

100, the rear wall 5. As the front wall 2, it is further approximately formed by the wall 2,

2, the front of FIG. formed from top to bottom in the middle of 2 to 5 is a wall

The sloping quadrangular frame with side walls 4a has a curvature 21 on the outer surface and a transverse flattening 6 is formed over its entire length. The walls are equally high, with a recess 7 formed at the upper face of the front wall which is formed between lava 3 and right wall 4 and with both animals, an acute angle. The depression 7 is circular with a radius of curvature R = 180 to 220 mm, preferably 210 mm, with a depth of 40 to 60 mm, preferably 50 mm in the central part.

As shown in FIG. 2, the front ends of the side walls

2a 4 extending upwardly so as to form protrusions 8 and 9, the front surfaces of which extend into the curvature 21 of the outer surface 20 of the front wall 2. The inner surface 22 of the front wall 2 is inclined at an angle α = 60 ° to 70 °, preferably 65 °. such that the front wall 2 tapers upwardly. As shown in FIG. 3, the rear corners of the slope element 1 are rounded.

In the slope element 1 of FIG. 4, a longitudinal elevation 12 in the form of a bar is formed on its front wall 2, to which tools or other working and alignment aids can be applied. As shown in FIG. 4, said elevation 12 extends continuously from the left side wall 2 to the right side wall 4. It is located approximately in the middle of the outer surface 20 of the front wall 2 and its face 121 is preferably oriented vertically, i.e. perpendicular to the base 100 of the slope element 1.

The rail elevation 12 of FIG. 4, top and bottom bounded by two surfaces, an upper surface 122 and a lower surface 123, which preferably extend parallel to the lower boundary contour, i.e. the base 100 of the slope element 1. The surfaces 122, 123 of the lath elevation 12 are raised above the outer surface 20 of the front wall 2 approximately 0.5 to 3 mm, preferably 1.5 mm.

In contrast to the embodiment of FIG. 1 has a slope element 1 according to FIG. 4 provided in the upper part of the front wall 2 with an oval depression 70 which is not limited by a single circular arc. Here again, however, the oval depression 70 adjoins the side walls 3, 4 so that an acute angle?

As shown in FIG. 5, the longitudinal elevation 12 may also extend through one of its side surfaces, preferably the lower surface 123 directly into the outer surface 20 of the front wall 2.

The slope element 1 has a variant according to FIG. 6, a recess 11 is formed on the upper side of each of the side walls 3, 4, which is closed from the outside and only opens into its cavity.

In the exemplary embodiment shown, a pair of opposing recesses 11 are formed approximately in the middle of the upper side of the two side walls 2r 4. Of course, the number and position of the individual recesses 11 can be arbitrarily selected.

Finally, a well recess 71 may also be formed on the rear wall 5 of the slope element 1, as shown in FIG. 6th

The flattening 6 of FIG. 2 gives the slope element 1 an optically easier impression. In addition, it saves concrete and makes it easier to handle. As already mentioned, the doming of the slope formed by the depression 7 or the well by the recess 71 does not prevent the growth of the plants, which can thus naturally develop, thereby obtaining slope coverage of the paved and grassed area without interrupting the area at the contoured edges. This also achieves a better natural appearance of the green area than with conventional elements.

Industrial usability

The slope element according to the invention can advantageously be produced in series, in particular from concrete or similar mixtures, and used in particular for strengthening and grassing larger sloping surfaces, for example sloping slopes around highways, railways and the like.
