Abstract

The set of paving blocks for the laying of curved paving consists in each case of a transition block (1) to be arranged on the outside and having four arcuate sides, in each case two mutually abutting sides (10, 18) being curved inwards and the remaining two sides (19, 20) being curved outwards so as to form a constant transition from one curve to another; on either side an equal number of curved blocks (2, 3, 4; 2a, 3a, 4a) formed as a mirror image to one another and which can adjoin the transition block, and crown blocks (5, 6, 5a, 6a; 7, 7a, 8) which are formed as a mirror image or symmetrically and can adjoin the curved blocks, and which each together have the same curve length, the whole being such that, in the paved state, the two outer edges (10) of the transition blocks (1) form an angle of 90 DEG and the height (H) of all the blocks, measured perpendicular to an imaginary base line (S) through the bottom corner points of the transition blocks (1), is the same. <??>In this arrangement, the blocks are formed from a bottom part having greater circumference in horizontal section and an upper part of smaller circumference in horizontal section, the lower part of the radial sides (21) of the curved and crown blocks and the outwardly arched sides (19, 20) of the transition blocks (1) being provided with a vertical toothing (14, 15) and the margin of the upper part having side faces which are irregular in shape as in the case of a natural stone. <??>A set of paving blocks of this type can be produced in a cost- effective manner, laid easily, and in the laid state approximates closely to curved paving formed from natural stones. <IMAGE>

Description

Bogenpflasterungen mittels Natursteinen sind schon seit sehr langen Zeiten bekannt, erfordern jedoch einerseits spezialisierte Fachleute zu deren Verlegung, und andererseits ist ein solches Pflaster sehr aufwendig, da die einzelnen Steine von Hand behauen werden. Obwohl Bogenpflasterungen aus natürlichen Steinen ästhetisch sehr wirkungsvoll und gefällig sind, werden die z.T. stark unebenen Oberflächen nicht von allen Personen geschätzt, insbesondere nicht von Frauen. Es war daher schon seit langem das Bestreben, Pflastersteine, respektive Pflastersteinelemente anzubieten, mittels derer eine Bogenpflasterung kostengünstig und mit ebenerer Oberfläche verlegt werden kann. So ist z.B. aus der EP-A-82 914 ein bogenförmiges Pflastersteinelement für die Verlegung einer Bogenpflasterung bekannt, bei welcher die Elemente durch nicht durchgehende Trennfugen in scheinbare Einzelsteine unterteilt sind, wobei diese Elemente im Vergleich mit Natursteinpflasterungen billiger herstellbar sind und leichter verlegt werden können. Infolge ihrer Konstruktion ergeben diese Elemente jedoch regelmässige und leicht erkennbare Fugen, währenddem die Herstellung der kreisbogenförmigen, relativ grossen Elemente mit herkömmlichen Formen ziemlich unwirtschaftlich ist. Ausserdem weichen diese Elemente relativ stark von der klassischen Bogenpflasterung ab, denn die äussersten beiden Teile der Elemente sind einander nicht gleich, wodurch sich kein stetiger Uebergang zwischen den einzelnen Bögen bilden kann. Ueberdies schränkt die Verwendung grosser Elemente deren Verwendung beim Uebergang zur Normalpflasterung und bei beschränktem Platz stark ein.Arch paving using natural stones has been known for a very long time, but on the one hand requires specialized experts to lay them, and on the other hand such a plaster is very complex since the individual stones are hewn by hand. Although arch paving made of natural stones is aesthetically very effective and pleasing, the partly. strongly uneven surfaces not appreciated by everyone, especially not by women. It has therefore long been the aim to offer paving stones or paving stone elements by means of which arch paving can be laid inexpensively and with a more even surface. For example, EP-A-82 914 discloses an arched paving stone element for laying arch paving, in which the elements are divided into apparent individual stones by non-continuous joints, these elements being cheaper to manufacture and easier to install than natural stone paving. However, due to their construction, these elements result in regular and easily recognizable joints, while the production of the circular, relatively large elements with conventional shapes is quite uneconomical. In addition, these elements deviate relatively strongly from the classic arch paving, because the outermost two parts of the elements are not identical to one another, which means that there can be no continuous transition between the individual arches. In addition, the use of large elements severely limits their use in the transition to normal paving and in a limited space.

Gattungsgemäße Pflastersteine Zum Verlegen einer Bogenpflasterung sind auch durch die DE-U-8400131 bekannt geworden.Generic paving stones for laying arch paving are also known from DE-U-8400131.

Es ist demgegenüber Aufgabe der vorliegenden Erfindung, Pflastersteine zur Verlegung einer Bogenpflasterung anzugeben, die einerseits rationell hergestellt werden konnen, und sich andererseits leicht verlegen lassen und ausserdem ein gefälliges Aussehen haben, das demjenigen einer Bogenpflasterung aus natürlichen Steinen nahekommt. Ausserdem sollen diese Pflastersteine mit anderen, geradlinig verlegbaren Pflastersteinen kompatibel sein. Diese Aufgabe wird mit den in den Ansprüchen beschriebenen Pflastersteinen gelöst.In contrast, it is an object of the present invention to provide paving stones for laying arch paving, which on the one hand can be produced rationally, and on the other hand can be easily installed and also have a pleasing appearance that comes close to that of arch paving made of natural stones. In addition, these paving stones should be compatible with other paving stones that can be laid in a straight line. This object is achieved with the paving stones described in the claims.

Die Erfindung wird im folgenden anhand einer Zeichnung von Ausführungsbeispielen näher erläutert.The invention is explained below with reference to a drawing of exemplary embodiments.

In Fig. 1 erkennt man zwei erfindungsgemässe Pflastersteinsätze zur Erstellung einer Bogenpflasterung. Der untere der beiden Sätze enthält an beiden Ecken je einen identischen Uebergangsstein 1, daran anschliessend drei Bogensteine 2, 3, 4, respektive die dazu spiegelbildlich geformten Bogensteine 2a, 3a und 4a. In diesem Bogen, respektive Pflastersteinsatz, schliessen sich an diese Bogensteine je zwei Scheitelsteine 5 resp. 5a und 6 resp. 6a an, wobei auch hier die beiden Scheitelsteine 5a und 6a spiegelbildlich zu den Steinen 5 und 6 ausgebildet sind. Der obere Bogen enthält ebenfalls die beiden Uebergangssteine 1 sowie die Bogensteine 2, 3, 4, resp. 2a, 3a und 4a. Anstatt der vier Scheitelsteine des unteren Bogens enthält der obere Satz zwei Scheitelsteine 7 resp. 7a, die ebenfalls spiegelbildlich zueinander geformt sind, sowie den obersten Scheitelstein 8. Die Bogenlänge der vier Scheitelsteine des unteren Bogens ist gleich derjenigen der drei Scheitelsteine der oberen Reihe, so dass diese Scheitelsteine wahlweise eingesetzt werden können.1 shows two paving stone inserts according to the invention for creating an arch paving. The lower of the two sets contains an identical transition stone 1 at both corners, followed by three arch stones 2, 3, 4, and the arch stones 2a, 3a and 4a formed in mirror image. In this arch, respectively paving stone set, two arch stones 5 resp. 5a and 6 respectively. 6a, the two apex stones 5a and 6a also being mirror images of the stones 5 and 6. The upper arch also contains the two transition stones 1 and the arch stones 2, 3, 4, respectively. 2a, 3a and 4a. Instead of the four crown stones of the lower arch, the upper set contains two crown stones 7 resp. 7a, which are also mirror images of each other, and the top apex 8. The arc length of the four apexes of the bottom Arch is the same as that of the three top stones in the top row, so these top stones can be used optionally.

Bei der Entwicklung des Pflastersteinsatzes wurde von dem Gedanken ausgegangen, ihn dem Aussehen nach bereits bekannten Pflastersteinen anzugleichen, um übergangslos in eine normale Pflasterung übergehen zu können, und um eine gewisse Normierung zu erreichen. Im bevorzugten Ausführungsbeispiel ist der Ausgangspunkt der rechteckige Normalstein eines unter dem Namen CITY PARK bekannten Pflastersteines, der in der EP-B-0060 961 eingehender beschrieben ist und in der vorliegenden Ausführungsvariante gemäss Fig. 4 mit dem Hinweiszeichen 9 versehen ist. Dieser quadratische Pflasterstein weist eine Kantenlänge von 180 mm auf, so dass das Raster in Fig. 1, d.h. der Abstand zwischen den Mittelpunkten bzw. die Diagonale der Uebergangssteine 1 ebenfalls 180 mm beträgt. Nimmt man eine der üblichen Breiten für einen Gehweg, d.h. 1250 mm als Spannweite S resp. Sehne eines Bogens, und stellt man die Bedingung, dass die Aussenkanten 10 der Uebergangssteine einen Winkel von 90° einschliessen sollen, ergibt sich als Radius r der Mittellinie M des Kreisbogens r = S/√2 = 883,9 mm. Wie bei Bogenpflasterungen üblich, weist der Bogen, senkrecht zur Sehne S gezogen, stets die gleiche Höhe H von 180 mm auf. Diese Zahlen und Masse sind als reine Beispielsangaben zu verstehen und beruhen zum grossen Teil auf der Vorgabe oder Wahl eines bestimmten Pflastersteines, von dem ausgegangen wird. Selbstverständlich kann von einem anderen Rastermass ausgegangen werden, so dass entweder eine grössere oder kleinere Anzahl Steine zu einem Satz gehören. Wichtig ist jedoch, dass die beiden Uebergangssteine an den Ecken identisch sind und die Anzahl der Bogensteine beidseitig gleich ist und diese spiegelbildlich geformt sind.The development of the paving stone set was based on the idea of adapting it to the appearance of previously known paving stones in order to be able to transition smoothly to normal paving and to achieve a certain standardization. In the preferred exemplary embodiment, the starting point is the rectangular normal stone of a paving stone known under the name CITY PARK, which is described in more detail in EP-B-0060 961 and is provided with the reference symbol 9 in the present embodiment variant according to FIG. 4. This square paving stone has an edge length of 180 mm, so that the grid in FIG. 1, ie the distance between the center points or the diagonal of the transition stones 1, is also 180 mm. If you take one of the usual widths for a walkway, ie 1250 mm as span S or. Tendon of an arc, and if the condition is met that the outer edges 10 of the transition stones should enclose an angle of 90 °, the radius r of the center line M of the circular arc is r = S / √2 = 883.9 mm. As is usual with arch paving, the arch, drawn perpendicular to the string S, always has the same height H of 180 mm. These numbers and masses are to be understood as examples only and are based to a large extent on the specification or selection of a specific paving stone that is assumed. Of course, a different grid dimension can be assumed, so that either a larger or smaller number of stones belong to a set. It is important, however, that the two transition stones at the corners are identical and that the number of arch stones is the same on both sides and that these are mirror images.

Es wurde jedoch nicht nur vom Mass des bekannten Pflastersteins 9 ausgegangen, sondern auch von dessen Aussehen und Formgebung. So ist eines der Merkmale des bekannten Pflastersteines, dass er in seiner Dicke, d.h. in vertikaler Richtung gesehen, zwei verschiedene Teile aufweist, wobei am unteren Teil mit grösserem Umfang eine Verzahnung angeordnet ist, und der obere Teil unabhängig von dieser Verzahnung derart ausgebildet ist, dass einerseits in versandetem Zustand die Verzahnung nicht sichtbar ist, und andererseits die Oberfläche das Aussehen eines Natursteines besitzt. Das bedeutet, dass die Seitenflächen des oberen Teils unregelmässig sind. Gemäss Fig. 5 besitzen sämtliche Steine des Satzes einen unteren Teil 11 mit grösserem Umfang im Horizontalschnitt und einen oberen Teil 12 mit unregelmässigen Seitenflächen, während die Oberfläche 13 wie in vorliegendem Beispiel leicht gewellt und daher rutschfest sein kann. Sämtliche Steine des Satzes mit Ausnahme der beiden Uebergangssteine 1 weisen am unteren Teil 11 der radialen Seiten 21 eine Verzahnung auf, die variabel ist, wie aus Fig. 1 hervorgeht. Die Verzahnung 14 und 15 der aneinanderliegenden Seiten der beiden Scheitelsteine 6 und 6a der unteren Reihe entspricht, s. Fig. 4, der Verzahnung des Normalpflastersteines 9 und weist je drei Nocken 16 auf, damit, wie in Fig. 4 gezeigt, gegebenenfalls mit einer Normalpflasterung übergangslos fortgefahren werden kann. In vorliegendem Beispiel ist also nur eine Verzahnung in radialer Richtung vorhanden. Dies gilt selbstverständlich auch für die Uebergangssteine, wo sich die Verzahnung naturgemäss an zwei anstossenden Seiten befindet.However, it was not only based on the size of the known paving stone 9, but also on its appearance and shape. Thus, one of the characteristics of the known paving stone is that it is thick, i.e. seen in the vertical direction, has two different parts, with a toothing is arranged on the lower part with a larger circumference, and the upper part is designed independently of this toothing in such a way that on the one hand the toothing is not visible in the sanded state, and on the other hand the surface Looks like a natural stone. This means that the side faces of the upper part are irregular. 5, all stones of the set have a lower part 11 with a larger circumference in horizontal section and an upper part 12 with irregular side surfaces, while the surface 13 can be slightly wavy and therefore non-slip as in the present example. All stones of the set, with the exception of the two transition stones 1, have a toothing on the lower part 11 of the radial sides 21 which is variable, as can be seen from FIG. 1. The toothing 14 and 15 of the adjacent sides of the two apex stones 6 and 6a corresponds to the lower row, see. Fig. 4, the toothing of the normal paving stone 9 and has three cams 16 each, so that, as shown in Fig. 4, if necessary, normal paving can continue seamlessly. In the present example, there is only one toothing in the radial direction. Of course, this also applies to the transition stones, where the teeth are naturally on two abutting sides.

Aus Fig. 1 geht hervor, dass die Verzahnung mit Ausnahme der eben beschriebenen Verzahnung an den Scheitelsteinen 6 und 6a an den verschiedenen Steinen nicht identisch ist. Von den Scheitelsteinen ausgehend erkennt man, dass die in der Mitte der Steine befindlichen Nocken stets nach aussen, d.h. zu den Uebergangssteinen hin weisen, und dass ihnen eine entsprechende Ausnehmung entspricht. Aus Fig. 1 geht ferner hervor, dass der Abstand von der Aussenkante eines Steines bis zur Nockenkante stets der gleiche ist, so dass die Länge der Nocken von der Mitte gegen den Uebergangsstein hin abnimmt. Die Uebergangssteine weisen an beiden aneinanderstossenden Seiten in der Mitte stets eine Ausnehmung auf, um die Nocken der nächsten Bogensteine aufzunehmen.From Fig. 1 it can be seen that the toothing with the exception of the toothing just described on the apex stones 6 and 6a on the different stones is not identical. From the apex stones you can see that the cams in the middle of the stones are always outwards, ie pointing towards the transition stones, and that a corresponding recess corresponds to them. 1 also shows that the distance from the outer edge of a stone to the cam edge is always the same, so that the length of the cams decreases from the center towards the transition stone. The transition stones always have a recess in the middle on both abutting sides to accommodate the cams of the next arch stones.

Aus Fig. 3 geht am ehesten hervor, dass alle vier Seiten der Uebergangssteine kreisbogenförmig gestaltet sind derart, dass ein stetiger Uebergang von einem Kreisbogen zum nächsten erfolgt, wie dies die Uebergangsstelle gemäss Fig. 3 deutlich erkennen lässt. Dabei sind zwei anstossende Seiten 18 nach innen und die anderen zwei Seiten 19 nach aussen gewölbt. Selbstverständlich sind die Kreisbogenseiten 22 und 22i der übrigen Steine auch derart gestaltet, dass der gewünschte Kreisbogen erzielt werden kann, während die radialen Seiten mit Ausnahme der an die Uebergangssteine angrenzenden Seiten der ersten Bogensteine 2 bzw. 2a geradlinig sind. Daraus ergibt sich ein stetiger Uebergang von einem Kreisbogen in den anderen ohne Stellen, die sich störend bemerkbar machen.3 most likely shows that all four sides of the transition stones are designed in the shape of a circular arc in such a way that there is a continuous transition from one circular arc to the next, as can clearly be seen from the transition point according to FIG. 3. Two abutting sides 18 are curved inwards and the other two sides 19 are curved outwards. Of course, the circular arc sides 22 and 22i of the other stones are also designed in such a way that the desired circular arc can be achieved, while the radial sides, with the exception of the sides of the first curved stones 2 and 2a adjoining the transition stones, are rectilinear. This results in a constant transition from one circular arc to the other without places that are noticeably disturbing.

Da die Pflastersteine auf Paletten angeliefert werden und jeder Stein eines Satzes seinen bestimmten Platz hat, ist es notwendig, die einzelnen Steine eines Satzes zu markieren. Im vorliegenden Beispiel geschieht dies durch eine bestimmte Anzahl Markierungsnuten 17 pro Stein, wie das in Fig. 1 angedeutet ist. Die Uebergangssteine 1, die sich ja von den übrigen Steinen insofern abheben, als sie an zwei aneinanderstossenden Seiten eine Verzahnung resp. keine Verzahnung aufweisen, müssen nicht markiert werden. Die ersten beiden Bogensteine 2 und 2a können dadurch gekennzeichnet werden, dass sie keine Markierung aufweisen, während die nächstfolgenden Steine eine, zwei oder drei Nuten aufweisen und die beiden Scheitelsteine 6 und 6a und der Scheitelstein 8 je eine bzw. zwei Nuten aufweisen. Da die beiden Scheitelsteine 6 und 6a auf einer ihrer Seiten eine andere Verzahnung aufweisen als die übrigen Steine, ist somit eine eindeutige Zuordnung dieser Steine leicht möglich. Dasselbe gilt für den Scheitelstein 8, der als einziger auf zwei entgegengesetzten Seiten Nocken aufweist. Aus Fig. 1 geht ferner hervor, dass die einzelnen Nuten stets derart an den Steinen angeordnet sind, dass sie im verlegten Zustand, bezogen auf die Basislinie S, stets senkrecht übereinanderliegen. Dadurch ist es möglich, beim Verlegen einzelne Steinspalten anhand dieser Nuten auszurichten.Since the paving stones are delivered on pallets and each stone of a set has its specific place, it is necessary to mark the individual stones of a set. In the present example, this is done by a certain number of marking grooves 17 per stone, as indicated in FIG. 1. The transition stones 1, which stand out from the other stones insofar as they have teeth or teeth on two abutting sides. have no teeth, do not have to be marked. The first two arch stones 2 and 2a can be characterized in that they have no marking, while the next stones have one, two or three grooves and the two crown stones 6 and 6a and the crown stone 8 each have one or two grooves. Since the two apex stones 6 and 6a have a different toothing on one of their sides than the other stones, a clear assignment of these stones is thus easily possible. The same applies to the crown stone 8, which is the only one having cams on two opposite sides. 1 also shows that the individual grooves are always arranged on the stones in such a way that, when laid, they always lie vertically one above the other in relation to the base line S. This makes it possible to align individual stone columns using these grooves when laying.

Neben den bereits erwähnten unterschiedlichen möglichen Dimensionen der Pflastersteine sind auch sämtliche bekannten Materialien sowie Einfärbungen zur Herstellung dieser Steine möglich, auch um diese Bogenpflastersteine an normale Pflastersteine anpassen oder einen bewussten Unterschied gestalten zu können.In addition to the different possible dimensions of the paving stones already mentioned, all known materials and coloring for the production of these stones are also possible, also in order to be able to adapt these arch paving stones to normal paving stones or to make a conscious difference.

Aus der Beschreibung geht hervor, dass diese Bogenpflastersteine auf der gleichen Maschine hergestellt werden können wie diejenige für die anderen Pflastersteine; natürlich mit anderen Formen.The description shows that these arch paving stones can be produced on the same machine as that for the other paving stones; with other shapes, of course.
