Description

Die vorliegende Erfindung betrifft einen Pflasterstein mit einer Bodenfläche, einer Deckfläche und einer Vielzahl von Seitenflächen, wobei auf mindestens einer Seitenfläche ein von dieser vorstehender vertikaler leistenförmiger Verbundabschnitt angeordnet ist, der bei der Erstellung eines Pflasters unter Herstellung eines Verbundes mit leistenförmigen Verbundabschnitten von Nachbarsteinen verschiebungssichernd zusammenwirkt.The present invention relates to a paving stone with a bottom surface, a top surface and a large number of side surfaces, with a vertical strip-shaped composite section protruding from this side surface being arranged on at least one side surface, which interacts with strip-shaped composite sections of neighboring stones to prevent displacement when a pavement is created, producing a bond .

Die vorliegende Erfindung bezieht sich auf einen Pflasterstein, der beliebig geformte Seitenflächen aufweisen kann, beispielsweise ebene Seitenflächen oder gekrümmte Seitenflächen. Beim Aneinandersetzen von mehreren Pflastersteinen zur Ausbildung eines Pflasters wirken hierbei die Verbundabschnitte der Pflastersteine miteinander zusammen, so dass sich ein Verzahnungseffekt nach Art von miteinander zusammenwirkenden Zahnstangen bzw. Zahnrädern ergibt. Darüber hinaus stellen derartige Verbundabschnitte eine Verschiebesicherung der Pflastersteine gegeneinander und daher eine entsprechende Verlegehilfe dar.The present invention relates to a paving stone which can have any shaped side faces, for example flat side faces or curved side faces. When several paving stones are placed next to one another to form a pavement, the composite sections of the paving stones interact with one another, resulting in an interlocking effect in the manner of cooperating toothed racks or gears. In addition, such composite sections prevent the paving stones from shifting against one another and therefore represent a corresponding laying aid.

Aus der EP 1 335 069 A2 ist ein Kunststein für Pflasterzwecke bekannt, der Verbundabschnitte aufweist, die am unteren Ende sockelförmig erweitert sind und sich nach oben hin verjüngen. Die sockelförmigen Erweiterungen sollen hierbei als Verlegehilfe das Aneinandersetzen der Steine erleichtern. Auch aus der DE 20 2006 013 475 U1 ist ein Pflasterstein mit Verbundabschnitten und unteren sockelförmigen Erweiterungen bekannt. Auch diese sockelförmigen Erweiterungen dienen als Verlegehilfe und sollen verhindern, dass die Pflastersteine bei hohen Verkehrslasten an den Verbundabschnitten hohen Flächenpressungen unterworfen sind.From the EP 1 335 069 A2 an artificial stone for paving purposes is known which has composite sections which are expanded in the form of a base at the lower end and taper towards the top. The base-shaped extensions are intended to make it easier to put the stones together as a laying aid. Also from the DE 20 2006 013 475 U1 a paving stone with compound sections and lower socket-shaped extensions is known. These base-shaped extensions also serve as a laying aid and are intended to prevent the paving stones from being subjected to high surface pressures on the composite sections when there are high traffic loads.

Die EP 1 036 882 A1 beschreibt einen Kunststein für Pflasterzwecke, der an seinen Seitenflächen Abstandshalter aufweist, wobei die Fläche des Abstandshalters zum Kontaktieren eines benachbarten Steines so klein ausgebildet ist, dass sie zwar beim Verlegen die Idealposition des Steines mit dem Soll-Fugenabstand sichert, jedoch beim Abrütteln des verlegten Pflasters zerstört wird. Auf diese Weise wird bei exakter Einhaltung des Soll-Fugenabstandes die gewünschte Elastizität des verlegten Pflasters sichergestellt. Der Abstandshalter soll auf den unteren Bereichen von Verbundabschnitten vorgesehen sein, so dass sich ein stufenförmiger Absatz ergibt.the EP 1 036 882 A1 describes an artificial stone for paving purposes, which has spacers on its side surfaces, the surface of the spacer for contacting a neighboring stone being designed so small that it secures the ideal position of the stone with the desired joint spacing when laying, but when the laid paving is vibrated gets destroyed. In this way, the desired elasticity of the laid pavement is ensured with exact compliance with the target joint spacing. The spacer is intended to be provided on the lower portions of bonded sections so that a stepped shoulder results.

DE 10 2007 015 831 A1 betrifft einen Betonpflasterstein, wobei genau ein Zahn an einer Steinrasterstrecke einen lotrechten unteren Zahnteil besitzt, der sich senkrecht zur Seitenfläche oberhalb der halben Steinhöhe über eine Schräge zu einem lotrechten oberen Zahnteil verjüngt und bei dem der oder die übrigen Zähne einer Steinrasterstrecke durchgängig über die gesamte Zahnhöhe so weit gegenüber den Seitenflächen vorspringen, wie der obere Zahnteil des ersten Zahns. Generell ist bei derartigen Pflastersteinen anzumerken, dass eine effektive Verschiebesicherung der Pflastersteine untereinander mithilfe von vorgesehenen Verbundabschnitten eine perfekte Fugenfüllung voraussetzt. Hierbei können sich jedoch die in der Regel engen Fugen beim Verfüllen mit Fugenmaterial oben zusetzen mit der Folge, dass die jeweilige Fuge nicht ordnungsgemäß verfüllt wird. Um dies zu verhindern, hat man bereits Verbundabschnitte so ausgebildet, dass sie sich von unten nach oben stetig verjüngen, wie dies beispielsweise in der vorstehend erwähnten EP 1 335 069 A2 der Fall ist. Diese Ausgestaltung hat jedoch folgenden Nachteil:
Bei einem Abrütteln des hergestellten Pflasters sowie bei Vibrationen durch Verkehr sorgt die Schwerkraft für eine Verdichtung des Fugenmateriales. Durch die geneigte Seitenwand der sich nach oben verjüngenden Verbundabschnitte treten dabei aber senkrecht auf die geneigte Seitenwand gerichtete, d. h. schräg nach oben gerichtete, Kräfte auf, die der Schwerkraft entgegenwirken. Die Kräfte neigen dazu, das Fugenmaterial zu lockern anstatt zu verdichten und dieses aus der sich schräg nach oben erweiternden Fuge zu entfernen. Jedenfalls wird hierdurch eine Lockerung des Fugenmateriales bewirkt, die der durch das Abrütteln angestrebten Verdichtung des Materiales entgegen wirkt. DE 10 2007 015 831 A1 relates to a concrete paving stone, with exactly one tooth on a stone grid section having a vertical lower tooth part which tapers perpendicularly to the side surface above half the height of the stone via a slope to a vertical upper tooth part and in which the one or more other teeth in a stone grid section are continuous over the entire tooth height protrude as far from the side surfaces as the upper tooth part of the first tooth. In general, with such paving stones, it should be noted that an effective anti-slip protection of the paving stones among each other with the help of intended bond sections requires perfect joint filling. Here, however, the usually narrow joints can be filled with jointing material clog at the top with the result that the respective joint is not properly filled. In order to prevent this, composite sections have already been formed in such a way that they gradually taper from bottom to top, as is the case, for example, in the above-mentioned patent EP 1 335 069 A2 the case is. However, this configuration has the following disadvantage:
If the paving produced shakes or if there are vibrations from traffic, gravity ensures that the joint material is compacted. Due to the inclined side wall of the upwardly tapering composite sections, however, forces occur which are directed perpendicularly onto the inclined side wall, ie are directed obliquely upwards, and which counteract the force of gravity. The forces tend to loosen rather than compress the joint material and remove it from the upwardly sloping joint. In any case, this causes a loosening of the joint material, which counteracts the compaction of the material that is aimed at by shaking.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Pflasterstein der eingangs beschriebenen Art zu schaffen, der im verlegten Pflaster eine besonders gute Fixierung der Fugenmaterialfüllung bewirkt.The present invention is based on the object of creating a paving stone of the type described at the outset which causes particularly good fixation of the joint material filling in the laid paving.

Diese Aufgabe wird erfindungsgemäß bei einem Pflasterstein der angegebenen Art dadurch gelöst, dass der Verbundabschnitt eine abgetreppte Form mit mindestens drei übereinander angeordneten stufenförmigen Absätzen besitzt, wobei die durch die stufenförmigen Absätze voneinander getrennten Verbundabschnittbereiche von unten nach oben immer weniger vorstehen.This object is achieved according to the invention with a paving stone of the type specified in that the composite section has a stepped shape with at least three stepped shoulders arranged one above the other, the shoulders being separated from one another by the stepped shoulders Composite section areas protrude less and less from bottom to top.

Die erfindungsgemäße Lösung sieht daher eine abgetreppte Ausführungsform des Verbundabschnittes bzw. der Verbundabschnitte vor. Hierdurch wird erreicht, dass die Aufweitung der entsprechenden Fuge nach oben nicht über eine steile Schräge, sondern treppenartig erfolgt, so dass auf das Pflaster einwirkende Kräfte, insbesondere Kräfte beim Abrütteln des Pflasters oder durch Verkehr, nicht schräg nach oben an der Fuge angreifen, sondern im Wesentlichen horizontal gerichtet sind. Diese Horizontalkräfte bewirken keine Auflockerung bzw. Entfernung des Fugenmateriales nach oben oder reduzieren derartige Kräfte, so dass im Wesentlichen von einer besseren Verdichtung der Fugenfüllung ausgegangen werden kann.The solution according to the invention therefore provides a stepped embodiment of the composite section or composite sections. This ensures that the corresponding joint does not widen upwards via a steep incline, but in a stair-like manner, so that forces acting on the pavement, in particular forces when the pavement is shaken or caused by traffic, do not act on the joint at an upward angle, but are directed essentially horizontally. These horizontal forces do not cause any upward loosening or removal of the joint material or reduce such forces, so that essentially better compression of the joint filling can be assumed.

Vorzugsweise erstrecken sich die stufenförmigen Absätze vollständig um die Verbundabschnitte herum, d. h. von einem Teil der Pflastersteinseitenwand bis zum anderen Teil der Seitenwand, so dass sich nirgendwo am Verbundabschnitt entsprechende Schrägflächen ergeben, die die vorstehend geschilderten Nachteile mit sich bringen. Der Verbundabschnitt setzt sich daher aus mehreren, d. h. mindestens drei übereinander angeordneten vertikal verlaufenden Verbundabschnittbereichen zusammen, die durch stufenförmige Absätze voneinander getrennt sind. Wichtig ist, dass der Verbundabschnitt eine treppenförmige Abstufung aufweist, die bewirkt, dass bei Krafteinwirkung auf den Pflasterstein keine schräg nach oben gerichteten, sondern horizontal wirkende Kraftkomponenten entstehen, die einer Lockerung bzw. einem Auswurf des Fugenmateriales entgegenstehen.The stepped shoulders preferably extend completely around the composite sections, ie from one part of the side wall of the paving stone to the other part of the side wall, so that there are no corresponding inclined surfaces anywhere on the composite section that entail the disadvantages described above. The composite section is therefore made up of several, ie at least three, vertically running composite section regions which are arranged one above the other and are separated from one another by stepped shoulders. It is important that the composite section has a step-like gradation, which means that when force is applied to the paving stone, there are no upwardly directed force components, but rather horizontally acting force components that prevent the joint material from loosening or being ejected.

Die Breite der jeweiligen stufenförmigen Absätze kann dabei gleich oder verschieden sein, je nach Gestaltung der Verbundabschnitte, die hierdurch mit ihren Bereichen mehr oder weniger vorstehen können.The width of the respective stepped shoulders can be the same or different, depending on the design of the composite sections, which as a result can protrude more or less with their areas.

Eine spezielle Ausführungsform der Erfindung zeichnet sich dadurch aus, dass die stufenförmigen Absätze von der Seitenfläche zum Vorderbereich des Verbundabschnittes hin nach unten geneigt ausgebildet sind, insbesondere unter einem Schrägwinkel von < 30 Grad. Diese geneigt ausgebildeten stufenförmigen Absätze verstärken den Effekt, dass das Fugenmaterial nach unten rutschen kann, so dass daher die Verdichtung begünstigt wird. Die hierdurch entstehenden schräg nach oben gerichteten Kraftkomponenten sind aufgrund der geringen Breite der stufenförmigen Absätze vernachlässigbar.A special embodiment of the invention is characterized in that the stepped shoulders are designed to be inclined downwards from the side surface to the front area of the composite section, in particular at an angle of inclination of <30 degrees. These inclined stepped shoulders increase the effect that the joint material can slide down, so that compaction is therefore promoted. The resulting obliquely upward force components are negligible due to the small width of the stepped shoulders.

Auch die Deckfläche des Verbundabschnittes ist vorzugsweise zum Vorderbereich des Verbundabschnittes hin nach unten geneigt ausgebildet. Insbesondere verläuft sie bevorzugt parallel zu den geneigt ausgebildeten stufenförmigen Absätzen.The top surface of the composite section is also preferably designed to be inclined downwards towards the front area of the composite section. In particular, it preferably runs parallel to the inclined stepped shoulders.

Der Verbundabschnitt kann sich über die gesamte Höhe eines Pflastersteines, d. h. von dessen Bodenfläche zu dessen Deckfläche erstrecken. Vorzugsweise erstreckt sich der Verbundabschnitt jedoch nur über ein Teil der Höhe eines Pflastersteines und endet vorzugsweise kurz vor dem Erreichen der Deckfläche. Bei mit Fugenmaterial gefüllter Fuge ist daher der Verbundabschnitt nicht mehr zu erkennen. Dies hat optische Vorteile und bewirkt darüber hinaus, dass mehr Fugenmaterial vorgesehen werden kann bzw. eine bessere Regenwasserversickerung erreicht wird.The composite section can extend over the entire height of a paving stone, i. H. extend from its bottom surface to its top surface. However, the composite section preferably extends over only part of the height of a paving stone and preferably ends shortly before reaching the top surface. When the joint is filled with jointing material, the composite section is no longer visible. This has visual advantages and also means that more joint material can be provided and better rainwater infiltration is achieved.

Was die Form des Verbundabschnittes betrifft, so ist dieser als vertikale Leiste ausgebildet, die im Horizontalschnitt vorzugsweise halbrund ausgebildet ist, wobei eine halbkreisförmige Gestalt oder eine trapezförmige Gestalt mit aufgesetztem Halbkreis besonders vorteilhaft ist. Diese abgerundeten bzw. schrägen Formen bewirken, dass das Fugenmaterial am Verbundabschnitt entlanggleiten kann und sich nicht an diesem verhakt. Der entsprechende Gleiteffekt ist dann besonders ausgeprägt, wenn sich ein Verbundabschnittbereich zwischen den stufenförmigen Absätzen oder mehrere Bereiche mit ihren seitlichen Abschnitten an die Seitenflächen des Pflastersteines anschmiegen, d. h. allmählich in diese übergehen. Dies wird besonders bevorzugt beim untersten Verbundabschnittbereich.As far as the shape of the composite section is concerned, it is in the form of a vertical strip which is preferably semicircular in horizontal section, with a semicircular shape or a trapezoidal shape with a semicircle placed on top being particularly advantageous. These rounded or sloping shapes mean that the joint material can slide along the composite section and does not get caught on it. The corresponding sliding effect is particularly pronounced when a composite section area between the stepped shoulders or several areas with their lateral sections nestle against the side surfaces of the paving stone, i. H. gradually transition into this. This is particularly preferred at the lowermost composite section area.

Bei einer speziellen Ausführungsform weist der Verbundabschnitt in seinem vordersten Bereich eine vertikale längliche Eintiefung auf. Eine derartige Eintiefung kann beispielsweise als Kerbe ausgebildet sein. Der Grund für die Anordnung einer derartigen Eintiefung bzw. Kerbe ist folgender:
Der wichtigste Bereich bei der Pufferung durch Fugenmaterial ist die kleine Zone zwischen dem vordersten Bereich bzw. der Spitze der Verbundabschnitte und der Seitenfläche des entsprechenden Nachbarsteines. Sobald die Fuge dazwischen nicht perfekt gefüllt ist, wird beim Abfüllen oder bei Vibrationen durch Verkehr das Fugenmaterial (Puffermaterial) gerade in dem für die Pufferung wichtigen oberen Steinbereich aus der Pufferungszone zwischen benachbarter Steinfläche und dem vordersten Bereich bzw. der Spitze bei einer gerundeten Ausbildung des Verbundabschnittes seitlich weggeschoben. Die Pufferung funktioniert möglicherweise gar nicht mehr. Um dies zu verhindern, sieht die Erfindung eine entsprechende vertikale Eintiefung vor, in der sich Fugenmaterial sammeln kann und einer seitlichen Verschiebung entgegenwirkt. Eine derartige mittige vertikale Einkerbung an der Spitze des Verbundabschnittes fixiert daher das Fugenmaterial im für die Pufferung wichtigsten Bereich. Auf diese Weise wird die Sicherung der Pufferung wesentlich verbessert.In a special embodiment, the composite section has a vertical, elongate indentation in its foremost region. Such an indentation can be formed, for example, as a notch. The reason for the The arrangement of such a depression or notch is as follows:
The most important area for buffering by joint material is the small zone between the foremost area or tip of the bonded sections and the side surface of the corresponding neighboring block. As soon as the joint between them is not perfectly filled, the joint material (buffer material) in the upper stone area, which is important for the buffering, is removed from the buffering zone between the adjacent stone surface and the foremost area or the tip with a rounded design of the stone during filling or vibrations caused by traffic Composite section pushed away to the side. Buffering may no longer work at all. In order to prevent this, the invention provides a corresponding vertical depression in which joint material can collect and counteract lateral displacement. Such a central vertical notch at the top of the composite section therefore fixes the joint material in the area most important for buffering. In this way, the security of the buffering is significantly improved.

Die Erfindung betrifft ferner ein aus einer Vielzahl von Pflastersteinen der vorstehend beschriebenen Art zusammengesetztes Pflaster.The invention also relates to a paving composed of a plurality of paving stones of the type described above.

Die Erfindung wird nachfolgend anhand von Ausführungsbeispielen in Verbindung mit der Zeichnung im Einzelnen erläutert. Es zeigen:

The invention is explained in detail below using exemplary embodiments in conjunction with the drawing. Show it:

Figur 1 zeigt vier Pflastersteine 1, die im Horizontalschnitt jeweils rechteckförmig ausgebildet sind. Die Pflastersteine 1 besitzen jeweils eine Bodenfläche, eine Deckfläche 2 und vier Seitenflächen 3. Jede Seitenfläche ist dabei mit zwei Paaren von Verbundabschnitten 4 versehen. Jeder Verbundabschnitt ist in der Form einer von der entsprechenden Seitenfläche 3 vorstehenden vertikalen Leiste ausgebildet, die sich von der Bodenfläche des Pflastersteines 1 nach oben bis kurz vor die Deckfläche 2 erstreckt. Im Horizontalschnitt hat jeder Verbundabschnitt 4 etwa die Form eines Trapezes mit einem daran angesetzten Halbkreis. figure 1 shows four paving stones 1, which are each rectangular in horizontal section. The paving stones 1 each have a bottom surface, a top surface 2 and four side surfaces 3. Each side surface is provided with two pairs of composite sections 4. Each composite portion is in the form of a vertical ledge protruding from the corresponding side face 3 and extending upwards from the bottom face of the paving stone 1 to just short of the top face 2 . In horizontal section, each composite section 4 has approximately the shape of a trapezium with a semicircle attached to it.

Die Paare der Verbundabschnitte 4 besitzen einen solchen Abstand voneinander, dass sie mit Paaren von Verbundabschnitten von Nachbarsteinen zusammenwirken können, um einen Pflasterverbund zu bilden. Im aneinandergesetzten Zustand der Pflastersteine greift dabei ein Verbundabschnitt eines Nachbarsteines in den Zwischenraum zwischen den beiden Verbundabschnitten 4 ein, wobei hierzwischen eine Fuge verbleibt, die sich von unten nach oben erweitert.The pairs of bonded sections 4 are spaced apart such that they can cooperate with pairs of bonded sections of neighboring blocks to form a pavement bond. When the paving stones are placed together, a bonded section of a neighboring stone engages in the space between the two bonded sections 4, with a joint remaining between them, which widens from bottom to top.

Die genaue Ausbildung eines Verbundabschnittes 4 ist in Figur 2 dargestellt. Der Verbundabschnitt 4 besitzt eine abgetreppte Form und hat bei dem hier dargestellten Ausführungsbeispiel von unten nach oben drei Verbundabschnittbereiche 5, 7 und 8, die durch zwei stufenförmige Absätze 11 und 10 voneinander getrennt sind. Am oberen Ende des Verbundabschnittes befindet sich eine Deckfläche 9. Die stufenförmigen Absätze 11, 10 und die Deckfläche 9 sind nach vorne und unten geneigt ausgebildet und erstrecken sich mit einem Schrägwinkel von < 30 Grad von der Seitenfläche des Pflastersteines aus.The precise formation of a composite section 4 is shown in FIG. The composite section 4 has a stepped shape and, in the exemplary embodiment shown here, has three composite section regions 5, 7 and 8 from bottom to top, which are separated from one another by two stepped shoulders 11 and 10. At the upper end of the composite section is a deck surface 9. The stepped shoulders 11, 10 and deck surface 9 slope forwards and downwards and extend at a slant angle of <30 degrees from the side face of the paving stone.

Durch die abgetreppte Ausbildung des Verbundabschnittes 4 erstrecken sich die drei übereinander angeordneten Verbundabschnittsbereiche 5, 7 und 8 in senkrechter Richtung. Die Verbundabschnittbereiche 5, 7 und 8 stehen daher von unten nach oben immer weniger von der entsprechenden Seitenfläche vor, so dass sich bei aneinandergesetzten Pflastersteinen eine entsprechende Fugenerweiterung ergibt. Eine Schräge bzw. eine sich nach oben verjüngende Ausbildung des Verbundabschnittes wird daher vermieden. Das hat den Vorteil, dass Kräfte, die senkrecht zur Oberfläche des Verbundabschnittes angreifen, beispielsweise beim Abrütteln eines entsprechenden Pflasters, in Horizontalrichtung nicht schräg aufwärts an der entsprechenden Fugenfüllung zwischen benachbarten Verbundabschnitten angreifen und somit im Wesentlichen keine Lockerung des eingefügten Fugenmateriales bzw. einen Auswurf desselben nach oben bewirken. Die entsprechende Verdichtung des Fugenmateriales wird daher im Wesentlichen nicht reduziert.Due to the stepped design of the composite section 4, the three composite section areas 5, 7 and 8 arranged one above the other extend in the vertical direction. The composite section areas 5, 7 and 8 therefore protrude less and less from the corresponding side surface from bottom to top, so that when the paving stones are placed next to one another there is a corresponding widening of the joint. An incline or an upwardly tapering configuration of the composite section is therefore avoided. This has the advantage that forces that act perpendicularly to the surface of the composite section, for example when a corresponding plaster is shaken off, do not act diagonally upwards in the horizontal direction on the corresponding joint filling between adjacent composite sections and thus essentially no loosening of the inserted joint material or ejection of the same effect upwards. The corresponding compaction of the joint material is therefore essentially not reduced.

Bei der in Figur 2 dargestellten Ausführungsform eines Verbundabschnittes 4 ist der unterste am weitesten vorstehende Verbundabschnittbereich 5 so ausgebildet, dass seine seitlichen Bereiche 6 in seitlicher Richtung erweitert sind und an diesen Stellen allmählich in die Seitenfläche des Pflastersteines sich an diese anschmiegend übergehen. Hierdurch wird in diesem Bereich u. a. ein Verhaken von eingefülltem Fugenmaterial verhindert.At the in figure 2 In the illustrated embodiment of a composite section 4, the lowermost, most protruding composite section area 5 is formed in such a way that its lateral areas 6 are widened in the lateral direction and at these points gradually merge into the side surface of the paving stone and nestle against it. In this way, inter alia, the filled joint material is prevented from getting caught in this area.

Bei der in Figur 3 dargestellten Ausführungsform eines Verbundabschnittes 15 hat dieser in seinem vordersten Bereich bzw. seiner Spitze eine sich in Längsrichtung des Verbundabschnittes erstreckende Eintiefung bzw. Einkerbung 14, die verhindert, dass zwischen dem vordersten Bereich des Verbundabschnittes 15 und der Seitenfläche des Nachbarsteines befindliches Fugenmaterial beispielsweise beim Abrütteln seitlich verdrängt wird, so dass der entsprechende Puffereffekt hierzwischen verloren geht. Die Eintiefung bzw. Einkerbung 14 hält Fugenmaterial an dieser Stelle zurück und sorgt auch hier für einen entsprechenden Puffereffekt durch Fugenmaterial.At the in figure 3 In the embodiment of a composite section 15 illustrated, this has in its frontmost area or its tip a depression or indentation 14 extending in the longitudinal direction of the composite section, which prevents the joint material located between the frontmost area of the composite section 15 and the side surface of the neighboring stone, for example when vibrating laterally is displaced, so that the corresponding buffer effect is lost in between. The indentation or indentation 14 holds back joint material at this point and also ensures a corresponding buffering effect through joint material here.

Statt einer Eintiefung bzw. Einkerbung 14 kann auch eine entsprechende Abflachung im vordersten Bereich des Verbundabschnittes vorgesehen sein, um an dieser Stelle einer seitlichen Verdrängung von Fugenmaterial entgegen zu wirken. Eine derartige Abflachung ist in Figur 2 angedeutet.Instead of a depression or notch 14, a corresponding flattening can also be provided in the foremost area of the composite section in order to counteract a lateral displacement of joint material at this point. Such a flattening is in figure 2 implied.
