Description

Die Erfindung betrifft einen Betonstein gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a concrete block according to the preamble of claim 1.

Aus der DE 102 05 135 A1 und der EP 1 105 576 B1 sind Betonsteine mit Verbundabschnitten bekannt, welche sich zu einer Steinoberseite hin verjüngen. Nachteilig an derartigen Verbundabschnitten ist, dass diese insbesondere in ihrem schlanken Kopfbereich relativ häufig Abplatzungen aufweisen, welche die Brauchbarkeit der Betonsteine negativ beeinflussen und regelmäßig durch den Kunden bemängelt werden.From the DE 102 05 135 A1 and the EP 1 105 576 B1 Concrete blocks are known with composite sections, which taper to a stone top. A disadvantage of such composite sections is that they have, in particular in their slender head area relatively frequently flaking, which adversely affect the usefulness of concrete blocks and are regularly criticized by the customer.

Der Erfindung liegt die Aufgabe zugrunde, einen Betonstein zu entwickeln, dessen Verbundabschnitte weniger Abplatzungen aufweisen als die Verbundabschnitte herkömmlicher Betonsteine.The invention has for its object to develop a concrete block whose composite sections have less flaking than the composite sections of conventional concrete blocks.

Diese Aufgabe wird ausgehend von den Merkmalen des Oberbegriffs des Anspruchs 1 durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. In den Unteransprüchen sind vorteilhafte und zweckmäßige Weiterbildungen angegeben.This object is achieved on the basis of the features of the preamble of claim 1 by the characterizing features of claim 1. In the dependent claims advantageous and expedient developments are given.

Der erfindungsgemäße Betonstein weist einen Verbundabschnitt auf, der einen Unterkörper, einen Mittelkörper und einen Kopfkörper umfasst, wobei der Unterkörper als Quader ausgebildet ist und eine Tiefe TA aufweist und wobei der Mittelkörper als Trapezsäule ausgebildet ist, welche auf der Seitenfläche steht und eine Tiefe TB aufweist, wobei sich die Tiefe TA des Unterkörpers und Tiefe TB des Mittelkörpers entsprechen und wobei der Kopfkörper als schiefer Pyramidenstumpf ausgebildet ist, welcher sich zu der Seitenfläche des Betonsteins neigt. Als Grund für die erhöhte Qualität von Verbundabschnitten mit einer derartigen Formgebung - es zeigen sich weniger Abplatzungen am Mittelkörper und am Kopfkörper des Verbundabschnitts - wird eine durch die Formgebung des Verbundabschnitts optimierte Betonströmung beim Befüllen und Verdichten der Form angesehen. Es wird angenommen, dass sich ein mit zunehmender Höhe des Verbundabschnitts verringernder waagrechter Querschnitt des Verbundabschnitts positiv auf die Vermeidung von Lufteinschlüssen und wenig verdichteten Bereichen auswirkt. Hinzu kommt die Vermutung, dass der Kopfkörper, welcher mit seinen drei Deckflächen nach oben gerichtet in einen Hauptkörper des Betonsteins mündet; Lufteinschlüsse und wenig verdichtete Bereiche in den Hauptkörper zurückleitet. Kern der Erfindung ist somit ein auf die Betonströmung beim Befüllen und Verdichten optimierter Betonstein.The concrete block according to the invention has a composite section comprising a lower body, a center body and a head body, wherein the lower body as a cuboid is formed and has a depth TA and wherein the center body is formed as a trapezoidal column, which stands on the side surface and has a depth TB, wherein the depth TA of the lower body and depth TB of the center body correspond and wherein the head body is formed as a slanted truncated pyramid, which slopes to the side surface of the concrete block. As a reason for the increased quality of composite sections with such a shape - there are fewer spalling on the center body and on the head body of the composite section - is considered by the shape of the composite section optimized concrete flow during filling and compression of the mold. It is believed that a horizontal cross section of the composite section decreasing with increasing height of the composite section has a positive effect on the prevention of air pockets and low density areas. In addition, there is the assumption that the head body, which opens with its three top surfaces directed upwards into a main body of the concrete block; Trapped trapped air and poorly compressed areas in the main body. The core of the invention is thus optimized for the concrete flow during filling and compaction concrete block.

Weitere Einzelheiten der Erfindung werden in der Zeichnung anhand von schematisch dargestellten Ausführungsbeispielen beschrieben.Further details of the invention are described in the drawing with reference to schematically illustrated embodiments.

In der Figur 1 ist eine perspektivische Ansicht eines Ausschnitts eines Betonsteins 1 gezeigt. Der Betonstein 1 Umfasst einen quaderförmigen Hauptkörper 2 und Nocken bzw. Abstandshalter bzw. Verbundabschnitte 3, welche an Seitenflächen 4 angeordnet sind. In der Figur 1 ist nur einer der Verbundabschnitte 3 sichtbar. Der Verbundabschnitt 3 besteht aus einem Unterkörper A, einem Mittelkörper B und einem Kopfkörper C. Der Unterkörper A ist als Quader Q ausgebildet, auf welchem der Mittelkörper B ruht. Dieser steht hierbei als Trapezsäule T auf der Seitenfläche 4. Auf der Trapezsäule T ist schließlich noch der Kopfkörper C angeordnet, welcher sich als schiefe Pyramide P an die Seitenfläche 4 lehnt.FIG. 1 shows a perspective view of a detail of a concrete block 1. The concrete block 1 comprises a cuboid main body 2 and cams or spacers or composite sections 3, which are arranged on side surfaces 4. In FIG. 1, only one of the composite sections 3 is visible. The composite section 3 consists of a lower body A, a center body B and a head body C. The lower body A is formed as a cuboid Q, on which the center body B rests. This stands here as a trapezoidal column T on the side surface 4. On the trapezoidal column T finally the head body C is still arranged, which leans as an oblique pyramid P to the side surface 4.

In der Figur 2 ist der Betonstein 1 aus einer in der Figur 1 dargestellten Pfeilrichtung II in Seitenansicht gezeigt. In dieser Ansicht ist erkennbar wie sich ab dem Mittelkörper B eine Breite B3 des Verbundabsehnitts zunehmend in Pfeilrichtung x verringert.FIG. 2 shows the concrete block 1 from an arrow direction II shown in FIG. 1 in a side view. In this view, it can be seen how, starting from the middle body B, a width B3 of the composite section is increasingly reduced in the direction of the arrow x.

In der Figur 3 ist der Betonstein 1 aus einer in der Figur 1 dargestellten Pfeilrichtung III in Seitenansicht gezeigt. Der Unterkörper A und der Mittelkörper B weisen gleiche Tiefen TA und TB auf. Eine Tiefe TC des Kopfkörpers C des Verbundabschnitts 3 verringert sich in die Pfeilrichtung x: auf einen Wert 0. Das heißt, aufsteigende Blasen bzw. aufsteigende gering verdichtete Bereiche treten in Pfeilrichtung w aus dem Verbundabschnitt 3 in den Hauptkörper 2 aus und werden hierbei durch Deckflächen 5, 6 und 7 des Kopfkörpers C in Richtung einer Oberseite 8 des Betonsteins 1 geleitet (siehe auch Figur 1 und 2).In FIG. 3, the concrete block 1 is shown in side view from an arrow direction III shown in FIG. The lower body A and the middle body B have equal depths TA and TB. A depth TC of the head body C of the composite portion 3 decreases in the arrow direction x: to a value 0. That is, rising bubbles or rising low-density portions emerge from the composite portion 3 into the main body 2 in the direction of arrow w, thereby becoming top surfaces 5, 6 and 7 of Head body C in the direction of an upper side 8 of the concrete block 1 passed (see also Figure 1 and 2).

In der Figur 4 ist schließlich eine Draufsicht auf den in der Figur 1 gezeigten Ausschnitt des Betonsteins 1 gezeigt. In dieser Ansicht ist erkennbar, wie sich eine Breite B6 der Deckfläche 6 in eine Pfeilrichtung y zu dem Hauptkörper 2 des Betonsteins 1 hin verjüngt und somit einer aufsteigenden Bewegung im feuchten Beton eine Dynamik gibt.Finally, FIG. 4 shows a plan view of the section of the concrete block 1 shown in FIG. In this view can be seen how a width B6 of the top surface 6 tapers in an arrow direction y to the main body 2 of the concrete block 1 and thus gives an upward movement in the wet concrete dynamics.

Die Erfindung ist nicht auf dargestellte oder beschriebene Ausführungsbeispiele beschränkt. Sie umfasst vielmehr Weiterbildungen der Erfindung im Rahmen der Schutzrechtsansprüche.The invention is not limited to illustrated or described embodiments. Rather, it includes developments of the invention within the scope of the patent claims.
