Abstract

The circular paved area comprises a number of radially outwardly widening wedge stones (6) hexagonal in plan view, between w for filling the intermediate space are rows of rectangular stones. Each wedge stone has two opposing parallel side surfaces (7,8 the same length. Each wedge stone has two opposing parallel side surfaces (7,8) of equal length and the two side surfaces (9,10) evolving fr the opposing side edges (21) form a right angle (11).

Description

The present invention relates to a circular pavement.

With "circular pavement" here is a pavement structure meant a lot of cobblestones, which laid in the form of abutting circular rings are, so that there is a total circular area whose The interior should also be filled with paving stones can, but usually has no paving stones. In the latter case is strictly speaking a circular ring, but also under the term "Circular pavement" should fall.

Find in the previously known circular pavement variants Combinations of wedge stones and rectangular stones Use, with several different types of wedge stones and at least one embodiment of a rectangular stone are needed. Here, in the inner circular rings Wedges with larger opening angles and in the outer ones Circular rings are used with smaller opening angles. Usually four or more stone formats are used for a circular pavement is needed.

The laying with the different stone formats that in each annulus (row of circles) to the different ones Combinations are very complicated and needed difficult to do without a template. Despite the Using different stone formats are radial Wedge joints cannot be avoided.

It is also known for circular paving only Use rectangular stones. However, this leads to relative big deviations from the pure circular shape and more or less large expansion of the joints.

The disadvantages described above prevent the Use of composite systems for circular paving. On Compound paving consists of with composite sections provided stones, the composite sections Interlocking stones in a form-fitting manner. Such composite plasters are used wherever Plasters are exposed to heavy loads. At a Such plasters may have certain joint widths in the Rule not to be exceeded. Lead widening inevitably to the loss of composite properties.

For these reasons, with conventional circular paving systems, if they have relatively large joints, no composite systems are made because the big ones radial wedge joints and the expansion of the in Circumferential joints have a composite effect to make impossible.

For these reasons, circular pavements have so far been used generally not in traffic areas or in public passable areas used. A need for heavy-duty circular pavement, on the other hand, does exist. In particular the increasingly important roundabout plants represent a large and certainly still growing area of application.

The present invention is based on the object To create circular paving with a particularly small number of stone formats gets along.

This object is achieved by a circular pavement solved, which is characterized in that it is along a Variety of from the center of the circle to the circumference circular chords running at equal intervals, each a variety of radially attached identical, expanding hexagonally radially outward Wedge stones and between the wedge stones in the same Radial position of adjacent circular chords for filling the Intermediate rows of rectangular stones, wherein each wedge stone two opposite parallel Has sides of the same length and that of the opposite side edges of the two parallel Side surfaces outgoing two side surfaces one form a right angle with each other.

In the circular pavement designed according to the invention at least only two stone formats are available Application, namely a wedge stone and a rectangular stone. Of course, different types of rectangular stones, for example square stones and rectangular stones, application Find. However, it is essential that one Wedge format is used, so that this Way considerably simplified the laying work.

The simplification through reduction shown above the circular pavement on just two stone formats achieved that the basis of the circular pavement Circle transformed into a polygon that closely approximates the circle becomes. The identical wedges are on the circular chords or the corresponding polygon lines of the polygon corners to the center. Between these radial Wedge stone rows are wedge-shaped, widening radially outwards Spaces exist that are adjacent to Rows of rectangular stones are filled. With others Words, between the wedge stones of the same radial position of neighboring Circular chords are rows of rectangular Stones present. This results in a with Polygon with wedge stones and rectangular stones - each according to the number of polygon corners - very close to the circular shape is coming.

According to the invention, therefore, no attempt is made to use of different stone formats or use the most exact possible adjustment of expanding joints to achieve a circle, but it will - if specified a circular area - this in a circle as close as possible coming polygon converted with wedge stones and Rectangular stones is occupied.

In the circular pavement designed according to the invention gaps of equal width that have no widening in have radial direction. The circular area can be defined by the used stone formats are covered completely, whereby the joint network without widening a clear geometric Line network forms.

There is a radial row of wedges along both sides an approximately zigzag joint line from the inside to the outside outside, which integrates the wedge stones into the system of Rectangular stones allows.

Since in the circular pavement designed according to the invention uniform joint widths can be maintained, the have no widenings, is the circular pavement Particularly suitable for a fully integrated system with which the Paving stones interlocked with each other have standing composite sections.

It is understood that the trained according to the invention Circular pavement is not the exact shape of a circle or Must have a circular ring. Rather, the term "Circular pavement" also cover circular segments that overlap a more or less large circumferential distance of a circle extend.

As already mentioned, the circular pavement according to the invention preferably formed as a composite plaster. Here are hence the wedge stones and rectangular stones of the pavement as Composite stones designed, each one or more composite sections have, which with the composite sections adjacent stones are in positive engagement. There the pavement formed according to the invention with a joint network has absolutely the same joint widths everywhere Composite sections not disengaged.

In a further preferred embodiment of the invention the circular pavement is designed as a so-called eco-pavement, the wedge stones and rectangular stones as so-called eco stones are designed. With such a "Ecoplast" is a plaster in which targeted relatively wide joints between the individual stones are arranged to allow rainwater to seep away enable. These relatively wide joints are over Spacers reached on the side faces of each Stones are provided.

The circular pavement designed according to the invention can be used as Have an outer concrete ring. Since it is in the circular paving according to the invention is therefore a polygon approximating a circle this concrete ring is also polygonal. If the outer concrete ring should be designed as a real circular ring the pavement polygon has to be cut by the stones the outer paving ring adapted to the real circular shape become. Such an embodiment takes place, for example use if the concrete ring before the arrangement of the Patch is made.

As mentioned, the trained circular pavement only two stone formats are used. This sets assuming that a single rectangular stone format is used becomes. Of course, different ones can also be used Rectangular stone formats can be used.

The wedge stone has two opposite parallel ones Side faces of the same length. From the opposite Side edges of the two parallel side faces go two Side faces that are at right angles to each other form. The stone is perpendicular to the parallel median planes of equal length symmetrical. This will make the wedge shape achieved that the two made a right angle with each other forming side surfaces of different lengths are, the in the installed state of the wedge shorter side surface points radially outwards. In the radial Placing two wedge stones together then forms between the adjacent side surfaces of the neighboring Stones again a right angle, so that a Rectangular blocks with the same joint width In practice, it is radial when installed outer side surface of the two at a right angle side faces forming one another are considerably shorter formed than the other side surface, so that the typical wedge shape results.

If here spoken of "hexagonal or hexagonal shape" this always refers to the top view. It it is understood that the stone is actually twice six Corners, i.e. Has 12 corners.

The circular paving 1 shown in plan view in FIG. 1 has approximately the shape of a circular ring, but is in Reality is a polygon approximated to a circular ring with a plurality of corners shown at 3. It is obvious that this polygon hardly differs from distinguishes a real circle or annulus, so that here is always spoken of a circular pavement when it does not have the shape of a real circle.

In the middle of the circular pavement there is a circular free space 2, for example with lawn, Plants etc. are planted or otherwise attached can.

The circular pavement is set in this embodiment composed of twelve concentric circular rings 20, which also have no real circular shape and each Have a polygonal character.

The circular pavement 1 is constructed so that it is along a Variety of from the center of the circle to the Circumference of the circumferential chord, d. H. leading from the center to the polygon corners Lines, each of a variety of radially stacked has hexagonal wedge stones 4. The exact form this key will be discussed below "Hexagonal" means here in plan view hexagonal.

These radial rows of wedge stones 4 have between rectangle stones 5, which the space between fill in the rows of wedges. The term "rectangular" refers here again on the top view. Between the wedge stones 4 of the same radial position adjacent Circular chords are therefore rows of rectangular stones 5 arranged with increasing distance from the center of the Circle have a greater length radially outwards. It can be seen that in the innermost pavement ring between two wedge stones arranged only a single rectangular stone while this is five for the outermost paving ring Rectangular stones are. It depends on the shape of the rectangular stones it doesn't matter. These can be square, narrow, wide etc. if you only use the space Fill in between the rows of wedge blocks.

With this arrangement of the wedge stones and rectangular stones there is a joint grid with the same width everywhere Put. In particular, the radial joints do not have any Widening to.

Figure 2 shows on an enlarged scale the arrangement of the Wedge stones 4 and rectangular stones 5.

The arrangement of the stones described above with the same The special shape of the Wedge 6 possible. This one has a top and one Bottom, which run parallel to each other. He owns also six corners and six side surfaces, which are shown in FIG run perpendicular to the leaf plane. Two side faces 7,8 run parallel to each other and have the same Length. From the opposite side edges of the two parallel side faces 7,8 go two more side faces 9, 10, which form a right angle with one another, as shown at 11. The one side surface 9 is the lies radially outside when the wedge is laid, significantly shorter than the other side surface 10, so that the stone takes the form of a wedge. One recognises in Figure 3 clearly that in this stone shape Side surface 9 also with the side surface 10 of the next Keilsteines forms a right angle 11, so that without additional rectangular blocks with the same joint width and the spaces between adjacent rows of wedges can fill out.

By varying the angle between the side surfaces 8 and 9 the angle at the outer polygon corners can be varied become. Is the angle between the side surfaces 8 and 9 exactly 180 °, the above can be described No longer apply patches. The smaller the angle , the more pointed the polygon corners become.

Figure 4 shows a plan view of a wedge 6 in an enlarged view Representation formed as a composite stone is. The basic shape of the stone corresponds to that of the stone of figure 3. In addition, however, the stone points to the Side surfaces spacers 12 on that with spacers of neighboring stones work together to target one Interlocking between adjacent stones and thus one Achieve bond effect.

FIG. 5 shows an enlarged top view of an eco composite stone, its basic form also with that of Figure 3 matches. This stone also instructs its side surfaces on composite sections 13, which with Interlock sections of adjacent stones, see above that a plaster is created that can take heavy loads can. Since with the patch described here no This causes the joints to diverge Pavement particularly good for such composite stones, because on this way the gearing of neighboring ones at every point Stones is ensured. In the embodiment of the FIG. 5, the composite sections 13 are so thick that that there is a particularly wide joint through which Rainwater seeps away and can be planted with greenery.
