Description
Die Erfindung bezieht sich auf ein Verfahren zum Fertigen von Betonsteinen oder Betonplatten verschiedener Formate und Größen, beim dem in Formen für mehrere Steine oder Platten Beton eingefüllt wird, nach den Oberbegriffen der Ansprüche 1 bis 3.The invention relates to a method for producing concrete blocks or concrete slabs of various formats and sizes, in which is poured into molds for several stones or slabs concrete, according to the preambles of claims 1 to 3.
Es ist üblich, zunächst den Rohbeton für Betonsteine und Betonplatten in die Formen einzufüllen, anschließend den Vorsatzbeton einzufüllen und dann die Betonsteine bzw. Betonplatten zu verdichten.It is customary first to pour the raw concrete for concrete blocks and concrete slabs into the molds, then to fill in the facing concrete and then to compact the concrete blocks or concrete slabs.
Es ist aber auch möglich, die Betonsteine bzw. Betonplatten in einem einstufigen Verfahren ohne Vorsatzbeton herzustellen.But it is also possible to produce the concrete blocks or concrete slabs in a one-step process without facing concrete.
Dabei ist es bekannt, der Oberflächenschicht bei dem einstufigen Verfahren bzw. der Vorsatzbetonschicht je nach Wunsch eine Grundfarbe zu geben, die ohne Einfärbung der Betonfarbe entsprechen kann oder mit verschiedenen Farben eingefärbt ist, um verschiedenfarbige Betonsteine oder Betonplatten herzustellen.It is known to give the surface layer in the single-stage process or the facing concrete layer as desired, a base color that can correspond without coloring the concrete color or is colored with different colors to produce different colored concrete blocks or concrete slabs.
Es ist weiterhin bekannt,
Die weiterhin bekannte, gattungsbildende
Ein Verfahren zum Herstellen von dekorierten Platten aus Beton ist aus der
Die
Die Herstellung von Oberflächen, die gemaserten oder gesprenkelten Natursteinen ähneln, ist nicht angesprochen. Angaben zur Korngröße des Materials in der bindemittelfreien Schicht gibt es nicht.The production of surfaces that resemble grained or speckled natural stones is not addressed. There is no information on the grain size of the material in the binder-free layer.
Aufgabe der Erfindung ist es daher, ein Verfahren zur Verfügung zu stellen, mit dem Oberflächen von Betonsteinen bzw. Betonplatten entstehen, die gemaserten und/oder gesprenkelten Natursteinen sehr ähnlich sehen. Dabei soll eine strukturierte Oberfläche entstehen, bei der gerichtete Adern und/oder Maserungen und/oder Sprenkelungen dominieren.The object of the invention is therefore to provide a method, arise with the surfaces of concrete blocks or concrete slabs, see the grained and / or speckled natural stones very similar. In this case, a structured surface is created in which directional veins and / or grains and / or speckles dominate.
Die Aufgabe der Erfindung wird dadurch gelöst, dass auf die Oberflächen- oder Vorsatzbetonschicht vor dem Verdichten mittels zumindest einer Aufbringvorrichtung zumindest eine Portion eines eingefärbten und/oder unterschiedlich eingefärbten oder eines farbigen bzw. unterschiedlich farbigen Veredelungsmaterials aufgeworfen wird. Dadurch besteht die Möglichkeit, geflammte, geaderte oder gesprenkelte Oberflächen zu erzeugen, die der natürlichen Struktur von Natursteinen ähnlich sehen. Durch Variationen der Aufbringvorrichtung, der Portion bzw. Portionen und des Veredelungsmaterials können diese Oberflächen erzeugt bzw. variiert werden. Dabei spielt auch die Grundfarbe der Oberflächen- oder Vorsatzbetonschicht eine Rolle, die von ungefärbtem Beton bis verschieden gefärbtem Beton reicht.The object of the invention is achieved in that at least one portion of a colored and / or differently colored or a colored or differently colored finishing material is thrown onto the surface or facing concrete layer before compacting by means of at least one applicator. This makes it possible to create flamed, veined or speckled surfaces that resemble the natural structure of natural stones. By variations of the applicator, the portion or portions and the refining material, these surfaces can be generated or varied. The basic color of the surface or facing concrete layer also plays a role, ranging from uncoloured concrete to differently colored concrete.
Unter "werfen" wird im verfahrenstechnischen Sinn auch "schleudern", "schießen" oder "blasen" des Veredelungsmaterials auf die Oberflächen- oder Vorsatzbetonschicht verstanden.In the process engineering sense, "throwing" is also understood to mean "hurling", "shooting" or "blowing" of the refining material onto the surface or facing concrete layer.
In vorteilhafter Weise ist das Veredelungsmaterial eine eingefärbte und/oder unterschiedlich eingefärbte Betonmischung, die aufgrund des Aufbringens auf die Oberfläche die besondere Optik ergibt. Dadurch, dass die Betonmischung anschließend in die Oberfläche eingedrückt bzw. dort verdichtet wird, ist eine gute Verbindung mit der Oberflächenschicht oder der Vorsatzbetonschicht gegeben.Advantageously, the finishing material is a dyed and / or differently colored concrete mixture, which results in the special appearance due to the application to the surface. The fact that the concrete mixture is then pressed into the surface or compacted there, a good connection with the surface layer or the facing concrete layer is given.
Das Veredelungsmaterial kann auch kleine Gesteinskörner aufweisen oder enthalten, so dass verschiedenartige Materialien mit unterschiedlichen Farben, auch Körnungen von Halbedelsteinen oder Edelsteinen oder Glimmer oder Metallspäne oder Kunststoffpartikel oder Glaspartikel in die Oberflächen- oder Vorsatzbetonschicht eingebracht werden können. Das Veredelungsmaterial kann auch eine beliebige Gesteinsmischung sein. Das Veredelungsmaterial hat eine abgestufte Kornzusammensetzung von max. 2 mm KorndurchmesserThe finishing material may also include or contain small aggregate grains such that various materials of different colors, including grades of semi-precious or precious stones or mica or metal chips or plastic particles or glass particles may be incorporated into the surface or facing concrete layer. The finishing material can also be any rock mix. The finishing material has a graded grain composition of max. 2 mm grain diameter
Der Vorsatzbeton oder die Beton-Oberflächenschicht hat einen feinkörnigen Kornaufbau, feiner oder gleich der Grenzsieblinie C4. C4 bezeichnet einen dem Fachmann bekannten feinkörnigen Kornaufbau von Körnungen zwischen 0 und 4,0 mm Durchmesser. Zur Beurteilung werden standardisierte Siebversuche mit festgelegten Siebmaschen durchgeführt.The facing concrete or the concrete surface layer has a fine-grained grain structure, finer or equal to the borderline line C4. C4 denotes a fine-grained grain structure known to those skilled in the art of grain sizes between 0 and 4.0 mm in diameter. For the evaluation, standardized screening tests are carried out with specified sieve meshes.
In einer aufgebrachten Portion können unterschiedliche Veredelungsmaterialien, unterschiedlich eingefärbte Betonmischungen einschließlich Gesteinskörnern oder Gesteinmischungen oder Körnungen oder Späne oder Partikel enthalten sein.In an applied portion may be included different finishing materials, different colored concrete mixtures including rock or rock mixtures or grains or chips or particles.
Es können- aber auch mehrere Portionen des gleichen oder unterschiedlichen Veredelungsmaterials pro Portion auf die Form aufgebracht werden, sowie mehrere Portionen des Veredelungsmaterials hintereinander auf die Oberflächen einer Form.But it can also be applied several portions of the same or different finishing material per serving on the mold, as well as several portions of the finishing material in a row on the surfaces of a mold.
Erfindungsgemäß wird vorgeschlagen, dass die Aufbringvorrichtung zumindest eine Schleuderscheibe oder ein Schaufelrad oder ein Wurfarm oder ein Katapult aufweist, denen die Portion oder die Portionen des Veredelungsmaterials zugeführt werden. Diese und die im Folgenden noch beschriebenen Aufbringvorrichtungen können sich über die Form oder neben der Form bewegen und es können ihnen auch unterschiedliche Portionen mit unterschiedlichem Zeitabstand zugeführt werden.According to the invention, it is proposed that the application device has at least one centrifugal disc or a paddle wheel or a limb or a catapult, to which the portion or the portions of the refining material are supplied. These and the application devices described below can move over the mold or next to the mold and they can also be supplied with different portions with different time intervals.
In einer weiteren Ausgestaltung wird vorgeschlagen, dass die Aufbringvorrichtung zumindest einen Veredelungsmaterial enthaltenden Dosierbehälter mit einer Dosierleiste aufweist, wobei der Dosierbehälter mit gleichmäßiger oder ungleichmäßiger Geschwindigkeit über die Form geführt wird.In a further embodiment, it is proposed that the application device has at least one dispensing container containing dispensing material with a dispensing strip, the dispensing container being guided over the form at a uniform or uneven speed.
Dabei werden auf die Dosierleiste vorzugsweise Vibrationen oder Rüttelstöße ausgeübt, die gleichmäßig und/oder ungleichmäßig und/oder intermittierend ausgeführt werden.In this case, vibrations or vibration impacts are preferably exerted on the dosing, which are performed evenly and / or non-uniformly and / or intermittently.
Der Dosierleiste können entlang ihrer Erstreckung unterschiedliche Veredelungsmaterialien und/oder unterschiedliche Portionen Veredelungsmaterial zugeführt werden.The dosing can be supplied along their extension different finishing materials and / or different portions of finishing material.
Der Dosierbehälter kann auch an der Vorderkante des Dosierwagens für den Vorsatzbeton angebracht werden.The dosing tank can also be attached to the front edge of the dosing trolley for the facing concrete.
Es wird weiterhin vorgeschlagen, die Aufbringvorrichtung als Rohrstutzen auszubilden, durch den die Portion oder die Portionen des Veredelungsmaterials auf die Oberflächen- oder Vorsatzbetonschicht geworfen werden. Eine besonders gute Verteilung auf die Form ergibt sich, wenn das Rohrstutzenende nach Art einer Düse ausgebildet ist.It is further proposed to form the applicator as a pipe socket through which the portion or portions of the finishing material are thrown onto the surface or facing concrete layer. A particularly good distribution on the shape results when the pipe socket end is designed in the manner of a nozzle.
Zur guten Verteilung trägt auch bei, dass der Auswurf mittels Druckluft erfolgt. Der Auswurf des Veredelungsmaterials kann auch mittels eines vorgespannten, federbelasteten Kolbens erfolgen, dessen Verrieglung zum Werfen plötzlich gelöst wird.For good distribution also contributes that the ejection is done by means of compressed air. The ejection of the finishing material can also by means a preloaded, spring-loaded piston done, the locking is released for throwing suddenly.
Vorzugsweise kann die Aufbringvorrichtung über die Form oder neben der Form bewegt werden. Sie kann dabei unterschiedliche Bewegungsgeschwindigkeiten aufweisen bzw. erreichen, wobei auch ein ruckartiges Bewegen vorteilhaft sein kann. Je nach Größe der Form und je nach farblicher Bestückung der Aufbringvorrichtung mit Veredelungsmaterial können auch mehrere und auch unterschiedliche Vorrichtungen für eine Form benutzt werden, damit eine Vergleichmäßigung des Wurfs oder ein spezielles charakteristisches Wurfbild des Veredelungsmaterials auf die Schichten erreicht wird.Preferably, the applicator can be moved over the mold or next to the mold. It can have or achieve different speeds of movement, whereby a jerky movement can be advantageous. Depending on the size of the shape and depending on the color placement of the applicator with finishing material also several and different devices can be used for a mold, so that a homogenization of the litter or a special characteristic throw pattern of the finishing material is achieved on the layers.
Vorzugsweise werden bei den Aufbringvorrichtungen Leitbleche benutzt, da derartige Scheibenräder oder Wurfarme und auch Rohrstutzen eine größere Streuung haben können.Preferably baffles are used in the application devices, since such disc wheels or limbs and pipe sockets can have a greater dispersion.
Durch die Aufbringvorrichtungen können mehrere Portionen des Veredelungsmaterials hintereinander ausgeworfen werden, wobei es sich dabei um unterschiedliche Veredelungsmaterialien, wie zuvor beschrieben, handeln kann.By the applicators several portions of the finishing material can be ejected in a row, which may be different finishing materials, as described above, act.
Weiterhin wird vorgeschlagen, dass die eingefärbte bzw. unterschiedlich eingefärbte Betonmischung oder auch der Vorsatzbeton oder die Beton-Oberflächenschicht kunststoffmodifiziert ist und/oder eine Silikat-Beton-Mischung aufweist.Furthermore, it is proposed that the dyed or differently colored concrete mixture or else the facing concrete or the concrete surface layer is plastic-modified and / or has a silicate-concrete mixture.
Die Gesteinskörner oder Gesteinskörnermischung oder Körnungen können mit einem organischen oder anorganischen Bindemittel angemischt werden. Das Bindemittel ist vorzugsweise farblos und wird vor dem Aufbringen mit den Gesteinskörnern oder -mischungen oder Körnungen oder Spänen oder Partikeln gemischt, wobei als organisches Bindemittel z.B. eine Acrylatdispersion und als anorganisches Bindemittel z.B. ein Silikat benutzt wird.The aggregate or aggregate mixture or granules may be mixed with an organic or inorganic binder. The binder is preferably colorless and is mixed prior to application with the rock grains or mixtures or grains or chips or particles, wherein as organic binder, for example, an acrylate dispersion and as an inorganic binder such as a silicate is used.
Vor, vorzugsweise aber nach dem Verdichten kann auf die Oberflächen der Betonsteine oder Betonplatten vor oder auch nach dem Aushärten ein organisches oder anorganisches Mittel, das vorzugsweise farblos ist, aufgebracht werden. Es handelt sich dabei um ein Imprägnieren, Versiegeln oder Beschichten der Betonsteine oder Betonplatten, wodurch eine erhöhte Haltbarkeit und ein Fleckenschutz erzielt sowie Kalkausblühungen vermindert oder verhindert werden.Before, but preferably after compacting, an organic or inorganic agent, which is preferably colorless, can be applied to the surfaces of the concrete blocks or concrete slabs before or even after curing. This involves impregnating, sealing or coating the concrete blocks or concrete slabs, which results in increased durability and stain protection, as well as reducing or preventing limescale efflorescence.
Die Oberflächen und /oder die Kanten der Oberflächen der Betonsteine oder Betonplatten können nach der Endverdichtung und vor der Versiegelung mit Bürsten bearbeitet und dabei strukturiert und/oder aufgerauht und/oder geglättet und/oder überstehende Ränder abgearbeitet werden.The surfaces and / or the edges of the surfaces of the concrete blocks or concrete slabs can be processed after the final compaction and before the sealing with brushes and thereby structured and / or roughened and / or smoothed and / or protruding edges are processed.
