Abstract

A method for producing concrete blocks for use in facades, covering layers etc. uses two densities of concrete; a dense mix (2) is used for most of the block and a light mix for the cladding layer (3). The dense mix is loaded first into the moulds, taking at least 90 percent of the volume after vibrating into place. The lighter cladding layer is added before the main block has set, to bond to the main block. A variation of the design has a light layer on both the underside and top of the blocks. The light layer can be worked to shape the outer appearance of the blocks.

Description

Die Erfindung betrifft einen Baustein aus Beton, insbesondere Schalungs- oder Blockstein, zur Erstellung von Bauwerken. Die Erfindung betrifft auch ein Verfahren zur Herstellung eines Bausteines aus Beton.The invention relates to a building block made of concrete, in particular Formwork or block stone, for creation of buildings. The invention also relates to a method for the production of a building block made of concrete.

Bisher aus der Praxis bekannt sind Bausteine, die aus Beton hergestellt werden. Bausteine, die eine hohe Maßgenauigkeit erfüllen müssen, werden im allgemeinen mechanisch nachbearbeitet. Dies gilt insbesondere für Plansteine und trocken zu versetzende Schalungs- oder Blocksteine. Die mechanische Nachbearbeitung kann dabei beispielsweise durch Fräsen erfolgen. So far known from practice are building blocks that consist of Concrete can be made. Building blocks that are high Dimensional accuracy must be met in general mechanically reworked. This applies in particular to Plan stones and formwork or Blocks. The mechanical post-processing can for example by milling.

Um ein Fräsen des Bausteines mit herkömmlichen Werkzeugen, z.B. aus Hartmetall, zu ermöglichen, muß ein entsprechender Beton mit einer geringen Rohdichte, wie z.B. Leichtbeton, gewählt werden, der leicht zu bearbeiten ist. Ein Einsatz von Normal- oder Schwerbeton eignet sich nicht zur Herstellung von Betonsteinen dieser Art, da der Beton aufgrund seiner Härte nicht mehr mit Hartmetallwerkzeugen bearbeitet werden kann. Zur Bearbeitung von Normalbeton und Schwerbeton sind im allgemeinen Diamantwerkzeuge notwendig, die entsprechende Kosten verursachen.To mill the block with conventional tools, e.g. made of hard metal, must be possible appropriate concrete with a low bulk density, such as e.g. Lightweight concrete can be chosen that is easy to work with is. Use of normal or heavy concrete is not suitable for the production of concrete blocks this type because the concrete is not due to its hardness can be machined with carbide tools. For processing normal and heavy concrete generally diamond tools necessary, the corresponding Cause costs.

Nachteilig bei Leichtbeton ist allerdings, daß der Leichtbeton im verarbeiteten Zustand im Bauwerk eine geringere Festigkeit und Härte aufweist, wie z.B. Normalbeton oder Schwerbeton. Auch das geringe Gewicht kann z.B. bezüglich des Schallschutzes nachteilig sein.A disadvantage of lightweight concrete, however, is that Lightweight concrete in the processed state in the building has lower strength and hardness, e.g. Normal concrete or heavy concrete. Even the low weight can e.g. disadvantageous with regard to sound insulation be.

Bisher aus der Praxis bekannt sind Verfahren zum Herstellen eines Bausteines aus Beton, in denen eine Form mit Beton ausgefüllt wird. Nach dem Einfüllen des Betons in die Form, wobei die Befüllung beispielsweise über einen Füllstutzen oder -wagen durchgeführt werden kann, wird die Form durch entsprechend angeordnete Vibratoren gerüttelt. Durch das Rütteln der Form setzt sich der Beton ab und wird dadurch verdichtet. Zusätzlich zur Rüttelung der Form wird durch den Einsatz eines entsprechenden Stempels bzw. einer Pressvorrichtung eine weitere Verdichtung des Betons erzielt. Processes for producing are known from practice to date of a building block made of concrete, in which a shape is filled with concrete. After pouring the concrete into the form, with the filling for example be carried out via a filler neck or trolley can, the shape is arranged accordingly Vibrators shaken. By shaking the mold sets the concrete comes off and is thereby compacted. In addition is used to shake the mold a corresponding stamp or a pressing device achieved further compaction of the concrete.

Die Höhe der Form muß die Höhe des fertigen Bausteines überragen, da der eingefüllte Beton vor der Rüttelung bzw. der Verdichtung durch den Stempel ein größeres Volumen aufweist. Die Form muß daher derart dimensioniert sein, daß sie die notwendige Betonmenge auch vor der Rüttelung und der Verdichtung mit dem Stempel aufnehmen kann.The height of the shape must match the height of the finished building block protrude because the poured concrete before shaking or the compression by the stamp a larger one Volume. The shape must therefore be dimensioned in this way be that they also provide the necessary amount of concrete the vibration and compaction with the stamp can.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Baustein und ein Verfahren zum Herstellen eines Bausteines aus Beton zu schaffen, durch das der Baustein günstig herzustellen ist, eine hohe Härte und Festigkeit aufweist und kostengünstig nachbearbeitet werden kann.The present invention is based on the object a building block and a method for producing a To create building blocks from concrete, through which the building block is inexpensive to manufacture, high hardness and Has strength and reworked inexpensively can be.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Baustein aus mindestens zwei Arten von Beton mit unterschiedlichen Rohdichten gebildet ist, wobei der Beton mit der niedrigeren Rohdichte wenigstens auf einer zu bearbeitenden Außenseite des Bausteines angeordnet ist.This object is achieved in that using the building block made from at least two types of concrete different bulk densities is formed, the Concrete with the lower bulk density at least arranged to be machined outside of the block is.

Dadurch, daß der Baustein aus Beton mit unterschiedlichen Rohdichten und daraus resultierend mit unterschiedlichen Eigenschaften gebildet ist, können die jeweils vorteilhaften Merkmale der verschiedenen Betonarten entsprechend eingesetzt werden. Durch einen Beton mit einer hohen Rohdichte erhält der Baustein eine hohe Härte, Festigkeit und Gewicht. Darüber hinaus ist Beton mit einer hohen Rohdichte, wie z.B. Normal- oder Schwerbeton, günstiger als ein Beton mit einer niedrigeren Rohdichte, wie z.B. Leichtbeton.The fact that the building block made of concrete with different Densities and, as a result, with different ones Properties is formed, the each advantageous features of the different types of concrete be used accordingly. Through a The building block receives concrete with a high bulk density high hardness, strength and weight. Furthermore is concrete with a high bulk density, e.g. normal or heavy concrete, cheaper than using concrete a lower bulk density, e.g. Lightweight concrete.

An den Stellen des Bausteines, an denen eine mechanische Nachbearbeitung notwendig ist, kann eine Betonart mit einer so niedrigen Betondichte eingesetzt werden, die eine Bearbeitung mit herkömmlichen Werkzeugen aus Hartmetall zuläßt. Durch die Ausbildung des Bausteines aus zwei Betonarten lassen sich alle an den Baustein gerichteten Forderungen erfüllen.At the locations of the building block where a mechanical Post-processing is necessary, a type of concrete with such a low concrete density, processing from conventional tools Allows carbide. Through the formation of the building block two types of concrete can all be attached to the building block meet directed demands.

Durch die Anordnung des Betons mit der niedrigeren Rohdichte auf einer Außenseite des Bausteines läßt sich der Baustein an dieser Außenseite besonders leicht bearbeiten. Ein Einsatz von Leichtbeton im Bereich der Außenseite des Bausteines hat sich als besonders vorteilhaft bezüglich der mechanischen Bearbeitung, z.B. durch Fräsen, herausgestellt. Durch diese Anordnung läßt sich der Baustein an der Außenseite leicht mit herkömmlichen Mitteln bearbeiten, während sein Kern durch den Beton mit einer höheren Rohdichte eine entsprechende Härte, Festigkeit und Gewicht aufweist. Durch den gezielten Einsatz des Betons mit der niedrigeren Rohdichte an der zu bearbeitenden Außenseite des Bausteines kommen die aus dem Leichtbeton resultierenden Vorteile voll zur Geltung, ohne daß der ganze Baustein in kostenintensiver Weise aus Leichtbeton hergestellt werden muß.By placing the concrete with the lower one Density on an outside of the block leaves the building block on this outside in particular easy to edit. Use of lightweight concrete in the area The outside of the building block has proven to be special advantageous in terms of mechanical processing, e.g. by milling. Through this The module can be arranged on the outside edit easily using conventional means while its core through the concrete with a higher bulk density has a corresponding hardness, strength and weight. Through the targeted use of the concrete with the lower bulk density on the outside to be machined of the building block come from the lightweight concrete resulting advantages to the fullest without the whole block in a cost-intensive way from lightweight concrete must be manufactured.

Von Vorteil ist es, wenn der Baustein mindestens zu 90 % aus dem Beton mit der höheren Rohdichte besteht. It is an advantage if the block is at least closed 90% consists of the concrete with the higher bulk density.

Durch den verstärkten Einsatz von Beton mit einer höheren Rohdichte erhält der Baustein eine besonders hohe Härte, Festigkeit und Gewicht. Außerdem ermäßigen sich die für die Herstellung des Bausteines notwendigen Materialkosten, da Beton mit einer höheren Rohdichte deutlich günstiger ist als Beton mit einer niedrigeren Rohdichte.Through the increased use of concrete with a higher The building block receives a special density high hardness, strength and weight. Reduce also necessary for the production of the module Material costs because concrete has a higher bulk density is significantly cheaper than concrete with a lower bulk density.

Ein erfindungsgemäßes Verfahren zur Herstellung des Bausteines aus Beton, insbesondere eines Schalungs- oder Blocksteines, zur Erstellung von Bauwerken, wobei der Beton in eine Form gefüllt, gerüttelt und verdichtet wird, besteht darin, daß in die Form mindestens zwei Arten von Beton mit unterschiedlichen Rohdichten eingebracht werden, wobei der Beton mit der niedrigeren Rohdichte wenigstens auf einer zu bearbeitenden Außenseite des Bausteines eingebracht wird.An inventive method for producing the Building blocks made of concrete, in particular a formwork or Blockstein, for the construction of buildings, whereby the concrete is filled into a mold, shaken and compacted is that at least in the form two types of concrete with different bulk densities be poured, the concrete with the lower Gross density at least on one to be processed Outside of the block is introduced.

Durch das Auffüllen der Form mit einem zweiten Beton, der eine andere Rohdichte aufweist, können die verschiedenen, durch die Rohdichte bedingten Eigenschaften von unterschiedlichen Arten von Beton miteinander kombiniert werden. Insbesondere ist es dadurch möglich, daß der Baustein nicht mehr komplett aus dem kostenintensiven Leichtbeton gefertigt werden muß, damit eine Nachbearbeitung gewährleistet ist. Das ist dadurch möglich, daß an den Stellen, an denen eine Nachbearbeitung des Bausteines notwendig ist, ein Beton verfüllt wird, mit dem dies in einfacher und, bezüglich des Einsatzes des notwendigen Werkzeuges, in kostensparender Weise mit herkömmlichen Hartmetallwerkzeugen möglich ist. In den Bereichen, in denen der Baustein eine besonders hohe Festigkeit oder Härte aufweisen sollte, kann analog dazu der entsprechende Beton verfüllt werden. Ein Einsatz von Beton mit einer hohen Rohdichte ist auch bezüglich der hierfür notwendigen geringen Materialkosten sinnvoll.By filling the mold with a second concrete, which has a different bulk density, the different properties due to the bulk density of different types of concrete with each other be combined. In particular, this makes it possible that the block is no longer completely from the costly lightweight concrete has to be manufactured, so that post-processing is guaranteed. This is possible that in the places where a Post-processing of the building block is necessary a concrete with which this is done in a simple and, with respect the use of the necessary tools, in cost-effective way with conventional carbide tools is possible. In the areas where the Building block a particularly high strength or hardness should have the corresponding analog Concrete to be filled. A use of concrete with a high bulk density is also necessary with regard to this low material costs make sense.

Erfindungsgemäß kann ferner vorgesehen sein, daß der zweite Beton mit der niedrigeren Rohdichte nach der Rüttelung des ersten Betons mit der höheren Rohdichte aufgefüllt wird.According to the invention it can further be provided that the second concrete with the lower bulk density after the Shaking the first concrete with the higher bulk density is replenished.

Durch das Rütteln des ersten Betons mit der höheren Rohdichte setzt sich dieser ab und es entsteht ein entsprechender Freiraum. In diesen Freiraum kann der zweite Beton mit der niedrigeren Rohdichte problemlos eingefüllt werden.By shaking the first concrete with the higher one The bulk density settles and it is created corresponding free space. In this free space second concrete with the lower bulk density without problems be filled in.

Vorteilhafte Weiterbildungen und Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen und aus dem nachfolgend anhand der Zeichnung prinzipmäßig beschriebenen Ausführungsbeispiel.Advantageous further developments and refinements of Invention result from the dependent claims and from the principle described below with reference to the drawing Embodiment.

Fig. 1 zeigt einen Baustein 1 zur Erstellung von Bauwerken. Der Baustein 1 besteht aus einem ersten Beton 2 mit einer hohen Rohdichte und einem zweiten Beton 3 mit einer niedrigeren Rohdichte.1 shows a building block 1 for the construction of buildings. Building block 1 consists of a first concrete 2 with a high bulk density and a second concrete 3 with a lower bulk density.

Die Außenwände des Bausteines 1 werden von einer Oberseite 4, einer Unterseite 5 und Seitenwänden 6 gebildet. Dabei besteht die Oberseite 4 des Bausteines 1 aus dem Beton 3 mit der niedrigeren Rohdichte. Die Unterseite 5 und die Seitenwände 6 bestehen aus dem Beton 2 mit der hohen Rohdichte.The outer walls of the block 1 are from an upper side 4, an underside 5 and side walls 6 are formed. There is the top 4 of the block 1 from the concrete 3 with the lower bulk density. The Bottom 5 and the side walls 6 consist of the Concrete 2 with the high bulk density.

Dadurch, daß die Oberseite 4 aus dem Beton 3 mit der niedrigeren Rohdichte, wie z.B. Leichtbeton, gebildet ist, kann die Oberseite 4 mit herkömmlichen Hartmetallwerkzeugen mechanisch bearbeitet, z.B. gefräst, werden. Diese Maßnahme ermöglicht es einen exakt ausgeformten Baustein 1 mit einer sehr hohen Maßgenauigkeit zu erzeugen. Somit können insbesondere nach diesem Verfahren hergestellte trocken zu verlegende Plansteine oder Schalungssteine maßgenau versetzt werden.The fact that the top 4 of the concrete 3 with the lower bulk density, e.g. Light concrete, formed is the top 4 with conventional carbide tools machined, e.g. milled, become. This measure enables a precisely shaped one Module 1 with a very high dimensional accuracy to create. Thus, especially after this Process manufactured dry stone to be laid or formwork blocks can be moved precisely.

Um die erforderliche Genauigkeit des Bausteines 1 durch entsprechende Nachbearbeitung zu erreichen, ist es im allgemeinen ausreichend, wenn die aus einem Beton 3 mit einer niedrigeren Rohdichte bestehende Schicht eine Stärke von ca. 10 mm aufweist. Dadurch ist es möglich, daß der Baustein 1 zu mindestens 90 % aus dem Beton 2 mit der höheren Rohdichte besteht. Der Baustein 1 erhält somit eine sehr hohe Festigkeit und Härte. Durch den prozentual hohen Anteil von Beton 2 mit der entsprechenden Festigkeit und Härte lassen sich bei dem Baustein 1 dünne Außenwände realisieren. Der Baustein 1 kann als beliebiger Baustein zur Erstellung von Bauwerken, insbesondere auch als Schalungs- oder Blockstein, ausgebildet sein. Der Baustein 1 kann auch mit einer nicht näher dargestellten Isolierung, wie sie beispielsweise bei Schalungssteinen üblich ist, versehen sein.To ensure the required accuracy of the module 1 can be achieved by appropriate post-processing it is generally sufficient if made from a concrete 3 existing with a lower bulk density Layer has a thickness of about 10 mm. Thereby it is possible that block 1 is at least 90% consists of the concrete 2 with the higher bulk density. Of the Module 1 thus has a very high strength and Hardness. Due to the high percentage of concrete 2 leave with the appropriate strength and hardness Realize thin outer walls with module 1. Building block 1 can be used as any building block of buildings, in particular also as formwork or block stone. The building block 1 can also be used with insulation (not shown), like for example with formwork blocks is common to be provided.

Fig. 2 zeigt den ersten Verfahrensschritt zur Herstellung des Bausteines 1. Dazu wird ein Beton 2 mit einer hohen Rohdichte in eine Form 7 verfüllt. Die Wände der Form 7 sind höher als der fertige Baustein 1. Dies resultiert daraus, daß der einzufüllende Beton 2 in unverdichtetem Zustand ein größeres Volumen besitzt. Die Form 7 wird daher bis in den Bereich ihrer Oberkante mit dem Beton 2 verfüllt. Bereits während des Verfüllens mit dem Beton 2 wird die Form 7 und somit der Beton 2 durch Vibratoren 8 gerüttelt. 2 shows the first process step for the production of the block 1. For this, a concrete 2 with a high bulk density in a mold 7. The walls of the Form 7 are higher than the finished building block 1. This results from the fact that the concrete to be filled 2 in uncompressed state has a larger volume. The form 7 is therefore in the area of its upper edge filled with concrete 2. Already during the Filling with the concrete 2 becomes 7 and thus the concrete 2 shaken by vibrators 8.

Wie aus Fig. 3 ersichtlich, setzt sich der Beton 2 durch die Vibratoren 8 ab und verdichtet sich somit. Nachdem der Beton 2 eingefüllt ist und sich aufgrund der Rüttelung der Vibratoren 8 abgesetzt hat, entsteht ein Freiraum 9 zwischen der Oberseite des Betons 2 und der Oberkante der Form 7.3, the concrete 2 settles by the vibrators 8 and thus condenses. After the concrete 2 is poured in and due has stopped vibrating the vibrators 8, arises a space 9 between the top of the concrete 2 and the top edge of shape 7.

In den Freiraum 9 wird, wie in Fig. 4 erkennbar, der zweite Beton 3 mit der niedrigeren Rohdichte, wie z.B. Leichtbeton, eingefüllt. Während und nach dem Einfüllen des Betons 3 erfolgt ebenfalls eine Rüttelung durch die Vibratoren 8.In the free space 9, as can be seen in FIG. 4, the second concrete 3 with the lower bulk density, e.g. Light concrete, filled. During and after filling the concrete 3 is also shaken through the vibrators 8.

Nach dem kompletten Einfüllen des Betons 3 erfolgt, wie Fig. 5 zeigt, eine Komprimierung der beiden Betonschichten 2, 3 durch einen Stempel 10 bzw. eine Pressvorrichtung. Dadurch werden die beiden Betonschichten 2, 3 in ihre Endstufe komprimiert und entsprechen somit den Ausmaßen des in Fig. 1 dargestellten fertigen Baustein 1. Durch das gemeinsame Verdichten entsteht eine hochbelastbare Verbindung zwischen den beiden Betonschichten.After the concrete 3 has been poured in completely, 5 shows a compression of the two concrete layers 2, 3 by a stamp 10 or a pressing device. This will make the two layers of concrete 2, 3 compressed in their final stage and thus correspond the dimensions of the finished one shown in FIG Module 1. The result of the joint compression a heavy-duty connection between the two Layers of concrete.

Das Einfüllen des Betons 3 erfolgt auf den noch feuchten Beton 2. Dadurch wird gewährleistet, daß eine feste und stabile Verbindung zwischen dem Beton 2 und dem Beton 3 entsteht. Je nach Bedarf kann der Beton 3 mit der niedrigeren Rohdichte sowohl auf der Oberseite 4 als auch auf der Unterseite 5 oder den Seitenwänden 6 des Bausteines 1 aufgebracht werden. The filling of the concrete 3 takes place on the still moist Concrete 2. This ensures that a solid and stable connection between the concrete 2 and the concrete 3 is formed. Depending on requirements, the concrete 3 with the lower bulk density on both the top 4 as well as on the bottom 5 or the side walls 6 of the block 1 are applied.

Der Beton 2 kann zur Erhöhung der Festigkeit und der Härte einen Quarzanteil aufweisen. Alternativ oder ergänzend dazu kann der Beton 2 auch einen Kiesanteil aufweisen. Der Beton 3 mit der niedrigen Rohdichte kann beispielsweise ein maximales Gewicht von 1400 kg/m3 aufweisen.The concrete 2 can have a quartz portion to increase the strength and hardness. As an alternative or in addition to this, the concrete 2 can also have a proportion of gravel. The concrete 3 with the low bulk density can, for example, have a maximum weight of 1400 kg / m 3 .
