Description

Paving element in the shape of a square slab

Technical field

BACKGROUND OF THE INVENTION The invention relates to a paving element in the form of a square slab with planar top and bottom sides and perpendicular planar peripheral areas thereof, each of which is symmetrical to the axis of symmetry extending through the center of the planar region. the distances and lengths are such that in the bond of the paving element with the same 10 paving elements the supporting extensions and the supporting extensions and the supporting extensions abut one another with a gap or closely.

BACKGROUND OF THE INVENTION

There are known paving elements in the form of a square plate, on the sides of which moldings are provided which serve as spacers and allow the formation of joints which can be filled with humus or mineral materials. Said paving elements are described in EP-A-0 274 344 and DE-U-87 17 484. Known paving elements allow only a few combinations 20 of laying.

EP 0 377 460 discloses paving element abutments which have a rectangular shape in rectangular rectangular free-angled corners with rectangular transitions to the circumferential surfaces of the paving element in horizontal section. In addition, the support extensions are arranged 25 at a distance from the corners. Aside from the fact that this embodiment increases the risk of breaking of the abutments and the formation of cracks in the transitions to the peripheral surfaces, this embodiment of the abutments also makes it difficult to remove the paving element from the mold and to form a bond between the paving elements. In addition, when laying the paving elements, there is a risk of sharp edges and burr injury at the free corners of the support extensions, and the formation of the individual 30 support extensions on adjacent circumferential surfaces results in tilting moments under heavy load on the pavement, for example.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a shape of paving element made of concrete material which has increased stability of corner areas and support extensions which is easy to remove from the mold during manufacture 35 and has a high load bearing capacity.

SUMMARY OF THE INVENTION

The problem is solved and the drawbacks of known paving elements of this kind largely eliminate the paving element in the form of a square slab with planar top and bottom and perpendicular planar areas of the peripheral surface, each symmetrical to the axis of symmetry running through the center of the planar area. spaced from this axis of symmetry are provided with abutments whose mutual distances and lengths are such that, in connection with the paving element with the same 45 abutment elements, they abut against each other with a gap or closely, according to the invention, at right angles to the adjoining area of the circumferential surface, they are provided with one support extension each in relation to the common corner and, in the case of a corner remote from the common corner, they are always provided with one support extension. than len and the supporting extensions 50, provided with the supporting extensions and the supporting extensions having, starting from the flat peripheral surface regions, on both sides towards the free ends of the inclined converging side walls which are defined by arcs in transition areas in the adjacent flat peripheral surface area; in areas of transitions into adjacent faces by additional arcs.

-1 CZ 287055 B6

This embodiment of the paving element has the advantage that the paving elements can be laid in a cross or tread relationship by using the abutment abutments, with a greater or lesser distance from each other, which allows a number of laying combinations. In addition, this convergent design of the abutments in conjunction with the abutment of the abutments in the area 5 of their feet and end faces facilitates the laying of the paving elements, since the shorter end faces of the abutments allow the abutment extensions of adjacent identical paving elements to snap together. . In addition, the paving elements are removed from the mold during manufacture and the risk of damage is reduced.

Preferably, the extensions have a height equal to the thickness of the paving element. Alternatively, it is also possible to use the solution in that the extensions have a height less than the thickness of the paving element and these extensions end below the surface level of the paving element, thus allowing for matching which appears to be gapless.

Furthermore, it may be advantageous if the abutments have a height less than the thickness of the paving element and at their end faces adjacent ends are defined at an inclined straight side with an arcuate portion and arcuate sections that extend in a flat region of the peripheral surface. Concrete facilitates the removal of paving elements of the shaping forms.
