Abstract
Description
Die vorliegende Erfindung befasst sich mit einem Formstein, dessen Oberfläche eine verhältnismäßig geringe Rauhigkeit aufweist, insbesondere mit einer Vorrichtung zur Herstellung von Formsteinen, deren Formgebung beliebig ist.The The present invention relates to a molded brick whose surface has a relatively low Has roughness, in particular with a device for manufacturing of shaped bricks whose shape is arbitrary.
Derartige
Formsteine sind aus der
Als nachteilig an derartigen Formsteinen wird es empfunden, dass bei einer geforderten verhältnismäßig glatten Oberfläche eine Nachbehandlung durch Auftragen einer weiteren Schicht oder durch Schleifen der Sichtoberfläche erforderlich wird. Infolge der Mehrschichtigkeit ist die Herstellung verhältnismäßig kostenintensiv und darüber hinaus zeitintensiv.When disadvantageous of such shaped bricks, it is felt that at a demanded relatively smooth surface an aftertreatment by applying another layer or by Sanding the visible surface is required. Due to the multi-layeredness is the production relatively expensive and above also time consuming.
Daher ist es Aufgabe der vorliegenden Erfindung, einen Formstein mit einer verhältnismäßig glatten Oberfläche bereitzustellen, der einfach und kostengünstig in der Herstellung und vielseitig verwendbar ist.Therefore It is an object of the present invention to provide a molded block with a relatively smooth surface to provide that simple and inexpensive to manufacture and is versatile.
Diese Aufgabe wird mit den kennzeichnenden Merkmalen der Hauptansprüche gelöst. Weitere erfindungswesentliche Merkmale sind den Unteransprüchen zu entnehmen.These The object is achieved with the characterizing features of the main claims. Further invention essential Features are the subclaims refer to.
Der erfindungsgemäße Formstein mit glatter Oberfläche aus einer einzigen Vergussmasse ist dadurch gekennzeichnet, dass die Vergussmasse ein Gemisch aus Sand, Zement, Wasser, einem Flussmittel und gegebenenfalls weiterer Zutaten, wie beispielsweise Porenbildnern, ist, wobei die Vergussmasse bis zur Aushärtung in wasserdichten Kunststofformen verbleibt und anschließend auf einem Rütteltisch entformt wird.Of the molded block according to the invention with a smooth surface From a single potting compound is characterized in that the potting compound is a mixture of sand, cement, water, a flux and optionally other ingredients, such as pore formers, is, wherein the potting compound until cured in waterproof plastic molds remains and then on a vibrating table is removed from the mold.
Vorteilhaft besteht die Vergussmasse aus einem Beton, dessen einzelne Komponenten im Wesentlichen vom jeweiligen Sand (Kies) abhängig ist.Advantageous The potting compound consists of a concrete whose individual components essentially depends on the particular sand (gravel).
Ferner ist es vorteilhaft, ein Fliessmittel zu verwenden, dessen Hauptwirkstoff ein Polycarboxylether ist.Further it is advantageous to use a flow agent whose main active ingredient a polycarboxylic ether.
Da die Vergussmasse bzw. der Beton einen verhältnismäßig hohen Wassergehalt aufweist, ist es vorteilhaft, die Rahmen der Formen wasserdicht auszubilden.There the potting compound or the concrete has a relatively high water content, It is advantageous to form the frame of the forms watertight.
Im Prinzip kann die Oberfläche des Formsteins jede beliebige Form annehmen.in the Principle can be the surface of the formstone take any shape.
Vorteilhaft ist es ferner, dass die Formen regelmäßig sind, insbesondere dann, wenn der Formstein für den Innenbereich verwendet wird.Advantageous it is also the case that the forms are regular, in particular, if the shaped brick for the interior is used.
Von besonderem Vorteil ist es, dass der gesamte Formstein einschichtig ist, das heißt, aus einer einzigen Vergussmasse besteht.From It is particularly advantageous that the entire molded block is single-layered is, that is, consists of a single potting compound.
Vorteilhaft ist es ferner, dass die Oberfläche des Formsteins infolge der Eigenschaft des selbstverdichtenden Betons durch Zutaten von Fließmitteln eine hohe Dichte aufweist.Advantageous it is further that the surface of the Formstone due to the property of self-compacting concrete by the addition of a flow agent high density.
Vorteilhaft ist es ferner, dass der selbstverdichtende Beton eine ausreichende Mehlkorn-Konzentration aufweist. Dazu ist es vorteilhaft, der Vergussmasse bzw. dem Beton eine vorbestimmte Menge an Feinsand und/oder Steinkohlenflugasche und/oder Steinmehl zuzugeben. Dabei richten sich die Anteile der einzelnen Komponenten nach der geforderten Rauhigkeit der Oberfläche des Formsteins.Advantageous It is also that the self-compacting concrete sufficient Meal grain concentration has. For this it is advantageous, the potting compound or the concrete a predetermined amount of fine sand and / or hard coal fly ash and / or Add stone flour. Here are the proportions of the individual Components according to the required roughness of the surface of the Shaped block.
Für manche Formsteine, insbesondere denen, die im Außenbereich Verwendung finden, ist es vorteilhaft, dass sich im gesamten Formstein, aber insbesondere an der Oberfläche Luftporen ausbilden, um eventuelle Frostschäden zu vermeiden. Das zu erzielen, ist es vorteilhaft, der Vergussmasse beim Mischen einen Zusatz von chemischen Porenbildnern zuzugeben.For some Shaped bricks, especially those used outdoors It is beneficial that throughout the block, but especially on the surface Form air pores to avoid possible frost damage. To achieve that it is advantageous to the casting compound during mixing an addition of Add chemical pore formers.
Weiterhin ist es vorteilhaft, dem Formstein bei der Herstellung zu bestimmende Farben zuzugeben, um der sichtbaren Oberfläche des Formsteins eine Farbgebung zu verleihen, was besonders vorteilhaft zur Verwendung im Innenbereich ist.Farther it is advantageous to determine the molded block in the production Add colors to the visible surface of the formstone a color scheme which is particularly advantageous for indoor use is.
Vorteilhaft ist es ferner, die Rahmen bzw. die Formen zum Auffüllen mit Vergussmasse aus Kunststoff, Holz oder Metall wasserdicht zu fertigen.Advantageous it is also, the frame or the forms to be filled with Casting compound made of plastic, wood or metal waterproof.
Im nun Folgenden wird die Erfindung anhand von Zeichnungen näher erläutert. Es zeigtin the Now, the invention will be explained in more detail with reference to drawings. It shows
