Hohrblockstein for plantable retaining walls

The invention relates to a hollow block for plantable retaining walls, with a cuboid basic shape and an opening that goes through from top to bottom.

In the course of environmental protection, efforts are made to be unavoidable To make retaining walls on roads, terraces, etc. plantable. The invention is based on the object for this to create a shaped stone that has various design options of plantable retaining walls and creates an aesthetic effect.

The task at hand is completed with a hollow block in the initially mentioned type solved according to the invention by j that at least one of its outsider edges is divided into two mirror-inverted curved sections whose The transition point is a flat one that is continuous from top to bottom

Bead forms and that its inner wall delimiting the Durohgang opening at least on two each other
opposite sides near its bottom one
Has graduation.

The curved side walls of the hollow brick with
their central bead not only make a special one
aesthetic appearance of the stone but give it
also increased strength against external pressure forces acting on the side walls, such as those that occur when setting such hollow blocks using mechanical gripping tools. The gradation of the inner wall allows insertion
of a base into the through opening which is expediently interrupted by no transverse wall. These floors prove to be particularly advantageous for retaining walls with a greater angle of inclination and in which the hollow blocks are set with gaps, because they prevent the slipping of
Prevent soil. The gradation of the inner wall can
expediently have a sloping step top that
not only facilitates the shaping of the hollow blocks, which are generally cast from concrete, but also one
Relatively close-fitting seat which of course results in insert floors provided with correspondingly sloping outer edges.

An exemplary embodiment of a hollow block designed according to the invention is described below with reference to the enclosed Drawing explained in more detail.

The one shown in the drawing, cuboid and made of Concrete cast hollow block 10 has an opening 11 extending from top to bottom. Its upper support surface 12 and lower support surface 13 are flat and correspond the thickness of the four side walls present at the respective end of the opening 11. All four side walls are in two each, to a vertical center plane 14 or 15 of the hollow block 10 is curved in mirror image Halves 16a, 16b, 17a, 17b, 18a, 18b and 19a, 19b structured, the one in the middle of the side walls at their transition point a flat top to bottom Form bead 20.
