Definitions
- the invention relates to a paving stone made of a rectangular concrete block with a substantially flat and embossed surface and with abutting surfaces formed at least on both sides of the corners of the concrete block, the side surfaces in the corner region of the concrete block being approximately circular and the abutting surfaces arranged on opposite sides being one have the appropriate spacing.
- Such paving stones are known and are usually laid with abutting abutting surfaces, which facilitates the alignment of the individual stones within the laying pattern and laid surfaces offer a visually appealing appearance. In this appearance, the concrete character often disturbs, since the impression of a natural stone paving is increasingly desired.
- An advantage of the concrete paving stone is that the tread can be made very simple, flat and smooth, which is very desirable, for example, in the area of pedestrian zones and promenades.
- a compromise known in this respect is offered by paving stones which are covered with natural stone slabs on their surface.
- paving stones are very expensive.
- Such concrete blocks are then post-treated on the surface after completion, such post-treatment usually consisting of sticks, for which various processing methods have also been developed. Stagnation allows you to achieve relatively flat, fine-roughened surfaces that are easy to walk on after laying, but have a pointed grain Have character and still clearly appear as a concrete block surface.
- the invention has for its object to provide a paving stone made of concrete, the walkable and visible after laying surface gives the impression of a natural stone surface.
- this object is achieved according to the invention in that the concrete block is provided with a rough attachment, which consists approximately of a third of different types of grit and trickle with a grain size less than 8/16, that the circular course with respect to individual corner areas has different radii of curvature and adjoins the adjacent abutting surfaces via an irregularly curved path, that the area running between two abutting surfaces lying on the same side surface in each case has an irregularly undulating curvature, and that the upper peripheral edge is broken out with a radius of curvature greater than 5 mm.
- Such a paving stone made of concrete, finished by bossing has a surface that largely corresponds to the appearance of a natural stone, with the irregularly shaped and thus also irregularly broken peripheral edges offering the appearance of a natural stone.
- This appearance is created in particular by the fact that the embossed surface with irregularly distributed cutouts up to 8 mm depth and the circumferential edge are irregularly broken out with radii of curvature between 5 and 10 mm. It is particularly provided that the larger radii of curvature of the upper peripheral edge in the area between Butt faces are and the butt faces are different widths.
- a third average joint surface is available if the length of the side surfaces of the concrete block is unequal, and that the total joint surface width is between 30 and 50%. the total length of the long side faces.
- the paving stone 10 is constructed from a conventional concrete as core concrete and a coarse facing concrete, which contains a higher proportion of coarse grain compared to the core concrete and the commonly used facing concrete.
- This higher proportion of coarse grain consists of different types of grit and Riesels and has a grain size of less than 8/16 with a share of about a third.
- this coarser granulation consists of 4/8 grit, 5/8 grit and 8/11 grit.
- the rest of the facing concrete has a normal grain size of 0/5.
- the proportions of grit and grit are varied both in terms of their quantity and in terms of their grain size. With this intended grain of the coarse facing concrete, the desired visual impression of a natural stone with the natural play of natural stone is obtained in the final processing of the surface provided as a tread by bossing.
- the irregularity of the broken-out upper edge 11 is also of decisive influence for the characteristic appearance of a natural stone. Therefore, the concrete block is formed irregularly with respect to its peripheral side surfaces, wherein in the plane corresponding to the grid dimension, butt surfaces 12 of different sizes are formed, between which one irregularly wavy curvature 14 of the side surface is provided.
- This irregular course of curvature also extends around the corners of the paving stone, a circular course of curvature with respect to individual corner regions 16 having different radii of curvature and connecting to the adjacent abutting surfaces 12 via an irregularly curved course.
- the regions of the side surface lying between the substantially flat abutting surfaces 12 are also designed to be irregularly curved.
- the surface of the concrete block provided as a tread is given an irregularly broken-out structure by the bossing and the coarser facing concrete, with irregularly distributed cutouts to depths of approximately 8 mm being provided over the surface.

Abstract
Description
Die Erfindung betrifft einen Pflasterstein aus einem rechteckigen Betonstein mit einer im wesentlichen ebenen und bossierten Oberfläche und mit jeweils zumindest beiderseits der Ecken des Betonsteins an den Seitenflächen ausgebildeten Stoßflächen, wobei die Seitenflächen im Eckbereich des Betonsteins etwa kreisförmig verlaufen und die auf gegenüberliegenden Seiten angeordneten Stoßflächen einen dem Rastermaß entsprechenden Abstand haben.The invention relates to a paving stone made of a rectangular concrete block with a substantially flat and embossed surface and with abutting surfaces formed at least on both sides of the corners of the concrete block, the side surfaces in the corner region of the concrete block being approximately circular and the abutting surfaces arranged on opposite sides being one have the appropriate spacing.
Derartige Pflastersteine sind bekannt und werden in der Regel mit einander anliegenden Stoßflächen verlegt, wodurch sich die Ausrichtung der einzelnen Steine innerhalb des Verlegemusters erleichtert und verlegte Flächen ein optisch ansprechendes Erscheinungsbild bieten. In diesem Erscheinungsbild stört häufig der Betoncharakter, da der Eindruck eines Natursteinpflasters zunehmend häufiger erwünscht ist. Ein Vorteil des Pflastersteins aus Beton besteht darin, daß die Lauffläche sehr einfach, eben und glatt ausgebildet werden kann, was zum Beispiel im Bereich von Fußgängerzonen und Promenaden sehr erwünscht ist.Such paving stones are known and are usually laid with abutting abutting surfaces, which facilitates the alignment of the individual stones within the laying pattern and laid surfaces offer a visually appealing appearance. In this appearance, the concrete character often disturbs, since the impression of a natural stone paving is increasingly desired. An advantage of the concrete paving stone is that the tread can be made very simple, flat and smooth, which is very desirable, for example, in the area of pedestrian zones and promenades.
Einen in dieser Hinsicht bekannten Kompromiß bieten Pflastersteine, die auf ihrer Oberfläche mit Natursteinplatten belegt sind. Derartige Pflastersteine sind jedoch sehr teuer. Es wurde jedoch auch schon versucht, durch besondere Zuschlagstoffe in dem Oberflächenbereich des Betonsteins eine Struktur zu schaffen, die einer Natursteinstruktur möglichst nahekommt. Derartige Betonsteine werden dann auf der Oberfläche nach der Fertigstellung nachbehandelt, wobei eine solche Nachbehandlung in der Regel aus Stocken besteht, wofür sich auch verschiedene Bearbeitungsmethoden herausgebildet haben. Durch das Stocken lassen sich verhältnismäßig ebene, feingerauhte Oberflächen erzielen, die nach der Verlegung angenehm zu begehen sind, jedoch einen spitzkörnigen Charakter haben und nach wie vor als Betonsteinoberfläche deutlich in Erscheinung treten.A compromise known in this respect is offered by paving stones which are covered with natural stone slabs on their surface. However, such paving stones are very expensive. However, attempts have also already been made to create a structure in the surface area of the concrete block by means of special aggregates that comes as close as possible to a natural stone structure. Such concrete blocks are then post-treated on the surface after completion, such post-treatment usually consisting of sticks, for which various processing methods have also been developed. Stagnation allows you to achieve relatively flat, fine-roughened surfaces that are easy to walk on after laying, but have a pointed grain Have character and still clearly appear as a concrete block surface.
Bei der Herstellung von Betonsteinen ist es üblich, vor dem Einbringen des Kernbetons in die Form einen Vorsatz einzufüllen, der bei herkömmlichen Betonsteinen eine Körnung von 0/5 hat. Dabei finden sowohl Splitt als auch Riesel Verwendung. Auch die Verwendung einer gröberen Körung für den Vorsatz ist bekannt, jedoch läßt sich bisher bei der Nachbearbeitung nicht das gewünschte, einem Naturstein sehr ähnliche Erscheinungsbild schaffen.In the production of concrete blocks, it is customary to fill in an attachment before placing the core concrete in the mold, which has a grain size of 0/5 for conventional concrete blocks. Both grit and grit are used. The use of a coarser grain size for the facing is also known, but so far the desired appearance, which is very similar to that of a natural stone, has not been able to be achieved in post-processing.
Der Erfindung liegt die Aufgabe zugrunde, einen Pflasterstein aus Beton zu schaffen, dessen begehbare und nach Verlegen sichtbare Oberfläche den Eindruck einer Natursteinoberfläche vermittelt.The invention has for its object to provide a paving stone made of concrete, the walkable and visible after laying surface gives the impression of a natural stone surface.
Ausgehend von dem eingangs erwähnten Pflasterstein wird diese Aufgabe erfindungsgemäß dadurch gelöst, daß der Betonstein mit einem groben Vorsatz versehen ist, der etwa zu einem Drittel aus verschiedenen Splitt- und Rieselsorten mit einer Körnung kleiner 8/16 besteht, daß der kreisförmige Verlauf bezüglich einzelner Eckbereiche unterschiedliche Krümmungsradien hat und über einen unregelmäßig gegengekrümmten Verlauf an die angrenzenden Stoßflächen anschließt, daß der zwischen zwei jeweils auf der gleichen Seitenfläche liegenden Stoßfläche verlaufende Bereich einen unregelmäßig gewellten Krümmungsverlauf hat, und daß die obere umlaufende Kante mit einem Krümmungsradius größer 5 mm ausgebrochen ist.Starting from the paving stone mentioned at the outset, this object is achieved according to the invention in that the concrete block is provided with a rough attachment, which consists approximately of a third of different types of grit and trickle with a grain size less than 8/16, that the circular course with respect to individual corner areas has different radii of curvature and adjoins the adjacent abutting surfaces via an irregularly curved path, that the area running between two abutting surfaces lying on the same side surface in each case has an irregularly undulating curvature, and that the upper peripheral edge is broken out with a radius of curvature greater than 5 mm.
Ein derartiger, durch Bossieren fertiggestellter Pflasterstein aus Beton hat eine Oberfläche, die weitgehend dem Erscheinungsbild eines Natursteines entspricht, wobei insbesondere die unregelmäßig geformten und damit auch unregelmäßig ausgebrochenen umlaufenden Kanten das Erscheinungsbild eines Natursteines bieten.Such a paving stone made of concrete, finished by bossing, has a surface that largely corresponds to the appearance of a natural stone, with the irregularly shaped and thus also irregularly broken peripheral edges offering the appearance of a natural stone.
Dieses Erscheinungsbild wird insbesondere dadurch geschaffen, daß die bossierte Oberfläche mit unregelmäßig verteilten Ausbrechungen bis zu 8 mm Tiefe und die umlaufende Kante unregelmäßig mit Krümmungsradien zwischen 5 und 10 mm ausgebrochen sind. Dabei ist insbesondere vorgesehen, daß die größeren Krümmungsradien der oberen umlaufenden Kante im Bereich zwischen Stoßflächen liegen und die Stoßflächen unterschiedlich breit sind.This appearance is created in particular by the fact that the embossed surface with irregularly distributed cutouts up to 8 mm depth and the circumferential edge are irregularly broken out with radii of curvature between 5 and 10 mm. It is particularly provided that the larger radii of curvature of the upper peripheral edge in the area between Butt faces are and the butt faces are different widths.
Um zu gewährleisten, daß der fertig bearbeitete Stein beim Verlegen die gewünschte Regelmäßigkeit des Verlegemusters bietet, ist ferner vorgesehen, daß bei ungleichem Verhältnis der Länge der Seitenflächen des Betonsteins eine dritte mittlere Stoßfläche vorhanden ist, und daß die Stumme der Stoßflächenbreiten zwischen 30 und 50% der Gesamtlänge der langen Seitenflächen liegt.In order to ensure that the finished stone offers the desired regularity of the laying pattern when laying, it is further provided that a third average joint surface is available if the length of the side surfaces of the concrete block is unequal, and that the total joint surface width is between 30 and 50%. the total length of the long side faces.
Die Vorteile und Merkmale der Erfindung ergeben sich auch aus der nachfolgenden Beschreibung eines Ausführungsbeispieles in Verbindung mit den Ansprüchen und der aus einer Figur bestehenden Zeichnung, aus der in perspektivischer Ansicht ein Pflasterstein gemäß der Erfindung schematisch hervorgeht.The advantages and features of the invention also result from the following description of an exemplary embodiment in conjunction with the claims and the drawing consisting of one figure, from which a paving stone according to the invention is shown schematically in a perspective view.
Der Pflasterstein 10 ist aus einem herkömmlichen Beton als Kernbeton und einem groben Vorsatzbeton aufgebaut, der gegenüber dem Kernbeton und dem üblicherweise verwendeten Vorsatzbeton einen höheren Anteil grober Körnung enthält. Dieser höhere Anteil grober Körnung besteht aus verschiedenen Splitt- und Rieselsorten und hat mit einem Anteil von etwa einem Drittel eine Körnung kleiner 8/16. Für eine spezielle Ausgestaltng ist zum Beispiel vorgesehen, daß diese gröbere Körnung aus Riesel mit der Körnung 4/8, Splitt mit der Körnung 5/8 und Splitt mit der Körnung 8/11 besteht. Der restliche Anteil des Vorsatzbetons hat eine übliche Körnung von 0/5. Je nach der Art des gewünschten optischen Eindruckes werden die Anteile von Riesel und Splitt sowohl bezüglich ihrer Menge als auch bezüglich ihrer Körnung variiert. Bei dieser vorgesehenen Körnung des groben Vorsatzbetons ergibt sich bei der abschließenden Bearbeitung der als Lauffläche vorgesehenen Oberfläche durch Bossieren der gewünschte optische Eindruck eines Natursteins mit dem einem Naturstein eigenen Farbspiel.The
Für das charakteristische Erscheinungsbild eines Natursteins ist auch die Unregelmäßigkeit der ausgebrochenen oberen Kante 11 von entscheidendem Einfluß. Daher wird der Betonstein bezüglich seiner umlaufenden Seitenflächen unregelmäßig ausgebildet, wobei in der dem Rastermaß entsprechenden Ebene Stoßflächen 12 unterschiedlicher Größe ausgebildet sind, zwischen denen ein unregelmäßig gewellter Krümmungsverlauf 14 der Seitenfläche vorgesehen ist. Dieser ungeregelmäßige Krümmungsverlauf erstreckt sich auch um die Ecken des Pflastersteins, wobei ein kreisförmiger Krümmungsverlauf bezüglich einzelner Eckbereiche 16 unterschiedliche Krümmungsradien hat und über einen unregelmäßig gegengekrümmten Verlauf an die angrenzenden Stoßflächen 12 anschließt.The irregularity of the broken-out
Auch die zwischen den im wesentlichen ebenen Stoßflächen 12 liegenden Bereiche der Seitenfläche sind unregelmäßig gekrümmt verlaufend ausgebildet.The regions of the side surface lying between the substantially flat
Bei dieser Ausgestaltng des Krümmungsverlaufs der Seitenflächen stellt sich beim Bossieren der Oberfläche auch ein unregelmäßig erscheinendes Ausbrechen der oberen umlaufenden Kante 11 ein, was sowohl durch den unregelmäßigen Krümmungsverlauf als auch durch die gröbere Körnung des Vorsatzes bedingt ist. Der Körnung des Vorsatzes entsprechend ergibt sich eine ausgebrochene obere Kante mit einem Krümmungsradius in der Größenordnung zwischen etwa 5 mm und 10 mm, wobei in einzelnen Bereichen auch unregelmäßig gegenläufige Ausbrechungen und größere Radien möglich sind, je nach dem, wie sich bei der Herstellung des Betonsteins die Körnung im Kantenbereich verteilt hat.With this configuration of the curvature of the side surfaces, when the surface is bossed, an irregular appearing breakout of the upper
Die als Lauffläche vorgesehene Oberfläche des Betonsteins erhält durch das Bossieren und den gröberen Vorsatzbeton eine unregelmäßig ausgebrochene Struktur, wobei über die Oberfläche unregelmäßig verteilte Ausbrechungen bis zu Tiefen von etwa 8 mm vorgesehen sind.The surface of the concrete block provided as a tread is given an irregularly broken-out structure by the bossing and the coarser facing concrete, with irregularly distributed cutouts to depths of approximately 8 mm being provided over the surface.
Da die Betonsteine im fortlaufenden Prozeß maschinell bossiert werden und auf der Bearbeitungsstrecke mit den Stoßflächen 12 aneinander anliegend durch den Bearbeitungsbereich laufen, ergibt sich infolge der gegengekrümmt verlaufenden Bereiche zwischen den Stoßflächen grundsätzlich ein etwas anders gearteter Verlauf der Ausbrechung der oberen Kante 11, da zwischen aneinander anstoßende Steine in diesen Bereichen freie Spalte vorhanden sind, in denen das Werkzeug am Stein etwas unterschiedlich angreift. Dieser Effekt wirkt sich weiterhin im Sinne der gewünschten Lösung aus, da dadurch das Ausbrechen der oberen umlaufenden Kante eine zusätzliche Unregelmäßigkeit erfährt. Im Interesse dieser unregelmäßigen Ausbrechungen ist auch vorgesehen, daß die Stoßflächen unterschiedlich breit sind und in ihrer Verteilung über die Seitenflächen des Betonsteins bezogen aufeinander gegenüberliegende Flächen seitlich verschoben sind. Dabei ist darauf zu achten, daß die Stoßflächenbreite genügend groß ist, um bei einem auf Knirsch verlegten Muster die dem Raster entsprechende Ausrichtung zu gewährleisten. Es hat sich gezeigt, daß dieses Ziel erreicht werden kann, wenn die Summe der Stoßflächenbreite zwischen etwa 30% und 50% der Gesamtlänge der Seitenflächen und insbesondere der langen Seitenfläche liegt.Since the concrete blocks are machined in the continuous process and run on the processing section with the
