Description

The invention relates to a concrete paving stone as arbitrary ashlar with or without upper chamfer and low-lying, vertical teeth and the teeth corresponding recesses on the sides.

On the one hand, paving stone surfaces have the task of being optimally navigable and accessible and, on the other hand, of counteracting a sealing of the surface, so that surface water optimally reaches the subsoil and is thus returned to the water cycle.

In both cases, the paving stone surface should have good composite properties, so that there are no deformations and displacements during use.

Another object is that the paving stone surface after grouting represents an area of substantially rectilinear paving stones and a composite effect is not recognizable.

It is known that for paving stone surfaces rectangular stones are used, which have low-lying on the straight side surfaces groups of teeth, which mesh when laying and should represent a composite effect. The so laid surface has optimal Beschheigenschaften, but is not suitable for heavy traffic areas, which will now be described.

The joints between adjacent paving stones should have a width of 3 to a maximum of 5 millimeters, so that this paving stone surface is optimally walkable and passable. With a wider joint there is also the danger that when sweeping (especially with sweepers) the joint is sanded and thus the composite effect between adjacent paving stones is repealed.

Since there may be some inaccuracies when laying paving stone surfaces, it makes sense to choose a 4 mm wide joint.

From the literature also shows that the deep-set teeth must take a 1 millimeter distance to the side of the adjacent paving stone, so that there is no "crunching". This means that with a joint of 4 millimeters, the frictional connection (the mutual overlap) between the teeth of adjacent paving stones is only 2 millimeters.

This is an unsatisfactory solution since it is no longer possible to speak of a frictional connection in the paving stone area over the teeth. High shear stresses that occur by driving, such cobblestone surfaces are not equal.

By the applicant a concrete paving stone is known, which has circumferentially projections and recesses. The teeth always come to lie in the region of the projections and form groups of teeth which are at a distance from each other. These concrete paving stones have optimal composite properties. However, the drainage of water is only slightly guaranteed in the area between the groups of teeth in the case of narrow laying. The upper appearance of these concrete paving stones after sanding represents a circumferential wave structure, which often leads to rejection in planners.

From the generic DE 297 02 544 U1 is an artificial stone for the attachment of outdoor traffic areas known, in which on the outside distance cams are attached, each side by a tooth and a matching tooth gap, seen in a circumferential direction of the stone, the teeth and the tooth gaps of all spacer cams in the same order lie next to each other. These spacer cams are used to form a wide joint.

Starting from the DE 297 02 544 U1 The object of the invention is to develop a concrete paving stone which is optimally navigable and accessible and, on the other hand, counteracts a sealing of the surface.

In both cases, the paving stone surface should have a good composite effect of the paving stones with each other.

Another object is that the paving stone surface after grouting represents an area of substantially rectilinear paving stones and a composite effect is not recognized.

These objects are achieved with the concrete paving stone described in claim 1.

The invention will now be explained in more detail with reference to the drawings.

Show it

1 and 2 each a concrete paving stone according to the invention in plan view,

3 the representation of a joint in the area of an external grid between two laid concrete paving stones before sanding,

4 a laid concrete paving stone surface with concrete paving stones behind 1 before sanding,

5 another concrete paving stone surface with concrete paving stones behind 1 and 2 before filling the joints,

6 the concrete paving stone surface of the 4 after sanding,

7 the concrete paving stone surface after 5 after filling the joints.

In 1 the concrete paving stone according to the invention is shown in plan view. On at least two concrete paving stone sides ( 1a ) is located on each outer grid track ( 2 ) in the region of the center (M) a group consisting of a large traction tooth ( 3 ), a well ( 4a ) to the stone interior and a smaller spacer tooth ( 5 ) exists as slip-off protection and not the entire outer grid line ( 2 ) occupies.

Here a concrete paving stone is shown, which on all concrete paving stone sides ( 1a ) two groups each of a large traction tooth ( 3 ), a well ( 4a ) to the stone interior and a smaller spacer tooth ( 5 ) has as slip-off protection.

The large traction tooth ( 3 ) lies on one side of the middle (M) of the outer grid track ( 2 ) while the depression ( 4a ) to the stone interior and the smaller spacer tooth ( 5 ) as Ausschlupfsicherung on the other hand, the middle (M) of the outer grid track ( 2 ) to find oneself.

The depressions ( 4a ) to the interior of the stone always have the same depth from group to group, but their transitions to the upper, straight stone outer edge ( 6 ) each formed differently.

The areas of the concrete paving stone sides ( 1a ) outside the individual groups of large traction tooth ( 3 ), a well ( 4a ) to the stone interior and a smaller spacer tooth ( 5 ) can have at least one irregularly shaped depression ( 4b ) to the stone interior. Here it is shown that only between the individual groups of large traction tooth ( 3 ) of a well ( 4a ) to the stone interior and a smaller spacer tooth ( 5 ) an irregularly shaped depression ( 4b ) lies to the stone interior.

2 shows a further concrete paving stone according to the invention in plan view. On only two adjacent concrete paving stone sides ( 1a ) are each two groups of a large traction tooth ( 3 ), a well ( 4a ) to the stone interior and a smaller spacer tooth ( 5 ) as slip-off protection and on the other two concrete paving stone sides ( 1b ) are again two larger full-width teeth ( 7 ) as the large traction tooth ( 3 ) formed in the region of the depressions ( 4a ) to the stone interior of the respectively opposite concrete paving stone sides ( 1a ) come to rest.

The areas of the concrete paving stone sides ( 1a ) outside the individual groups of large traction tooth ( 3 ), a well ( 4a ) to the stone interior and a smaller spacer tooth ( 5 ) as well as the areas of the concrete paving stone sides ( 1b ) outside the even larger wide-joint teeth ( 7 ) can have at least one irregularly shaped depression ( 4b ) to the stone interior.

In 1 and 2 you can see that the upper chamfer ( 8th ) continuously parallel to the upper outer contour of the concrete paving stone, ie to its upper, straight stone outer edges ( 6 ) and to the depressions ( 4a . 4b ) runs to the stone interior.

3 shows a joint in the area of an external grid ( 2 ) between two laid concrete paving stones before sanding.

The large gluteal teeth ( 3 ) of adjacent concrete paving stones lie side by side and each protrude into the depression ( 4a ) to the stone interior. The smaller spacer teeth ( 5 ) are located in the area of the upper, straight stone outer edges ( 6 ) behind the large traction teeth ( 3 ) of the adjacent concrete paving stone and constitute a slip prevention.

Now it is clear that a Betopflasterstein realized according to the invention, a large adhesion of adjacent concrete paving stones on the teeth.

In 4 is a laid concrete paving stone surface with concrete paving stones behind 1 presented before sanding.

It becomes clear that the individual concrete paving stones have an optimal composite effect all around. Between the interlocking groups of one large traction tooth ( 3 ), a well ( 4a ) to the stone interior and a smaller spacer tooth ( 5 ) are longer joints, which ensure optimal water flow.

Since in these areas the concrete paving stone sides have irregularly shaped depressions ( 4b ) to the stone interior, the water drainage is supported.

5 shows another concrete paving stone surface with concrete paving stones ( 10 ) to 1 and Betapflastersteinen ( 11 ) to 2 before filling the joints.

It can be seen that the wide-joint teeth ( 7 ) into the depressions ( 4a ) to the stone interior of the adjacent concrete paving stone. Which unilaterally by the large traction tooth ( 3 ) and on the other side by the smaller spacer tooth ( 5 ) are limited.

It becomes clear that concrete paving stones ( 10 ) to 1 in combination with concrete paving stones ( 11 ) to 2 can be laid without the frictional connection is lost in the paving stone surface. Thus, easily wide-paved pavement surfaces alternate with narrow-paving pavement surfaces.

In 6 you can see the concrete paving stone area after 4 after sanding.

The 4 to 7 had to be slightly oversubscribed because of the reduced drawing, so that the gear system was well visible.

Because the depressions ( 4a . 4b ) to the inside of the stone in reality only have a depth of about 2 millimeters and are always shaped differently, these come back after sanding and then no system can be detected.

Now it is clear that the paving stone surface created in this way constitutes an area composed of substantially rectilinear concrete paving stones.

7 shows the concrete paving stone area 5 after filling the joints.

Concrete paving stone surfaces are manufactured according to the state of the art, in which the joints of the narrow-pored concrete paving stone surfaces are filled with sand and the joints of the wide-jointed concrete paving stone surfaces are filled with chippings for better water drainage.
