Abstract

Facing panels for walls, floors, facades, etc., are produced by (a) filling a mould with a water-soluble slurry, (b) adding a hydraulic concrete material, (c) drying and removing the excess granules, (d) placing a plastic layer in position, so that the granules become entirely embedded, and a flat surface results, (e) curing the plastic, and (f) removing the slurry with water. The process gives facing panels consisting of a plastic layer, on one side of which a layer of granules embedded, to give the effect of the original hydraulic concrete. The panels have a lower weight, and are thinner than traditional concrete panels. The panels have high flexilibity, strength, and resistance to acids and weathering.

Description

  

  
 



  Verfahren zur Herstellung von Verkleidungsplatten
Die Erfindung betrifft ein Verfahren zur Herstellung von Verkleidungsplatten für Wände, Böden, Fassaden, usw.



   Es ist bekannt, derartige Verkleidungsplatten als sog. Waschbetonplatten herzustellen, welche jedoch in ihren Einsatzmöglichkeiten wegen ihres vergleichsweise hohen Gewichtes und   Materialaufwandes    sowie ihrer statischen Eigenschaften und ihrer Wetterbeständigkeit begrenzt sind.



   Von diesem Stand der Technik ausgehend, liegt der Erfindung die Aufgabe zugrunde, ein Verfahren zur Herstellung von Verkleidungsplatten zu schaffen, welches in einfacher Weise durchführbar ist und bei welchem die so erstellte Verkleidungsplatte das Aussehen einer Waschbetonplatte erhält, jedoch deren Eigenschaften wesentlich verbessert.



   Das erfindungsgemässe Verfahren ist dadurch gekennzeichnet, dass in eine Form eine wasserlösliche Schlämme eingefüllt und in diese ein körniges mineralisches Material eingebracht wird, wobei das kleinste Korn etwa zur Hälfte in die Schlämme eingebettet wird, anschliessend nach Trocknung der Schlämme und Entfernen des überschüssigen Korns auf das in der getrockneten Schlämme fest eingebundene körnige Material eine Kunststoffschicht aufgebracht wird und nach Erhärten des Kunststoffes die Schlämme mit Wasser entfernt wird. Die Form wird vorzugsweise zum Aufbringen der Schlämme waagerecht hingestellt, wobei die Formfläche aus Metall bestehen kann.

  Bei der   Schlämme    handelt es sich zweckmässig um eine schnelltrocknende Schlämme, beispielsweise Karboxymethylzellulose, Polyvinylalkohol oder ein Bindemittel auf Kaseinbasis, die jeweils mit Kalziumkarbonat und Quarzmehlen gefüllt werden kann. In die frische Schlämme, die in gewünschter Stärke gleichmässig aufgebracht werden kann, wird ein körniges, mineralisches Material, wie z. B. Quarz (Frechener Quarz), Kies (Weserkies, Rheinkies), Basalt, Marmor, Splitt usw.



  eingebracht, z. B. eingewalzt oder eingerüttelt.



   Von der gewählten Form und Grösse der Körner hängt die Auftragsdicke der Schlämme ab, und zwar ist diese so bemessen, dass das kleinste Korn des körnigen, mineralischen Materials etwa zur Hälfte in der Schlämme eingebettet wird. Bei Verwendung von Frechener Quarz von 8-10 mm Korn kann die Auftragsdicke der Schlämme vorteilhaft so bemessen werden, dass die Körnung ca. 4 mm tief eingebettet wird.



   Nach Trocknung der Schlämme, was durch Beheizung der Form beschleunigt werden kann, ist das Korn fest in die Form eingebunden. Die Form wird dann zweckmässig senkrecht gestellt, damit das überschüssige Korn entfernt wird und daher in der Form nur die durch die Schlämme festgehaltene Kornschicht verbleibt.



   Auf diese Vorsatzschicht wird, vorzugsweise in waagerechter Lage, eine Kunststoffschicht aufgebracht, vorzugsweise eine aus der Gruppe der Duroplaste, z. B. ungesättigte Polyesterharze, Epoxydharze, Harze auf Methylmetakrylat sowie die Abwandlungen der vorgenannten, und zwar vorteilhaft in solcher Stärke, dass das nicht in die Schlämme eingebettete Korn von der aufgebrachten Kunststoffschicht überdeckt ist und eine ebene Fläche entsteht.



   In die frische Kunststoffschicht können Anker, Rabitzgewebe oder Fertigelemente aus Beton, Leichtbeton, Gasbeton, Schaumbeton, Holz, Metall usw., eingesetzt werden.



   Nach dem Erhärten des Kunststoffes kann die Platte aus der Form genommen werden, und die Schlämme wird mit Wasser entfernt, so dass die fertige Verkleidungsplatte vorliegt.



   Die besonderen Vorteile des erfindungsgemässen Verfahrens bestehen darin, dass die auf diese Weise hergestellten Platten ein geringeres Gewicht und eine geringere Stärke besitzen können als die herkömmlichen Waschbetonplatten, und zwar betragen die entsprechenden Werte nur etwa   25 0/0    jener für die üblichen Waschbetonplatten. Des weiteren können die erfindungsgemäss hergestellten Platten beispielsweise mit hohen Druck- und Biegezugfestigkeiten, grosser   Elastizität, absoluter Wetterbeständigkeit und Säurefestigkeit hergestellt werden und sie bieten auch farbige Gestaltungsmöglichkeiten.



   Aufgrund dieser Eigenschaften ergeben sich zahlreiche Verwendungsmöglichkeiten, von denen einige beispielsweise erwähnt seien.



   Bei der Fassadenverkleidung können wegen des günstigen Gewichtes grössere Platten ohne besondere Anker im Mörtelbett oder mit Baukleber, z. B. ein Gemisch aus Zement und Quarzmehl, oder Polyvinylpropionat in Verbindung mit Methylzellulose verlegt werden. Altbauten können mit besonderen Befestigungen nachträglich verkleidet werden.



   Wegen der hohen Klebkraft, des geringen Gewichtes und der absoluten Wetterbeständigkeit der erfindungsgemässen Platten können Fertigteilelemente aus Gasbeton, Schaumbeton, Blähtonbeton, Holzbeton, Bimsbeton, Schlackenbeton, Ziegelsplittbeton und sonstige Leichtbau- und Betonelemente bei der Fertigung ohne besondere Verankerungen mit den Kunststoffplatten verbunden werden.



   Aufgrund der chemischen Beständigkeit der Platten können diese in Betrieben, wie Schlachthäusern, Fischfabriken, Molkereien, galvanischen Betrieben usw., als tritt- und rutschfeste Beläge verlegt werden.



   Darüber hinaus bestehen weitere Anwendungsmöglichkeiten, zumal der Kunststoff den verschiedensten Bedürfnissen in seiner Farbgebung sowie in seinen Eigenschaften angepasst werden kann. 



  
 



  Process for the production of cladding panels
The invention relates to a method for producing cladding panels for walls, floors, facades, etc.



   It is known to produce cladding panels of this type as so-called exposed aggregate concrete panels, which, however, are limited in their possible uses due to their comparatively high weight and material expenditure as well as their static properties and their weather resistance.



   Proceeding from this prior art, the invention is based on the object of creating a method for producing cladding panels which can be carried out in a simple manner and in which the cladding panel thus produced has the appearance of an exposed aggregate concrete panel, but its properties are significantly improved.



   The method according to the invention is characterized in that a water-soluble sludge is poured into a mold and a granular mineral material is introduced into it, about half of the smallest grain being embedded in the sludge, then after drying the sludge and removing the excess grain on the In the dried sludge firmly bound granular material a plastic layer is applied and after the plastic has hardened the sludge is removed with water. The mold is preferably placed horizontally for applying the slurry, it being possible for the mold surface to consist of metal.

  The sludge is expediently a quick-drying sludge, for example carboxymethyl cellulose, polyvinyl alcohol or a binder based on casein, which can each be filled with calcium carbonate and quartz flour. In the fresh sludge, which can be applied evenly in the desired strength, a granular, mineral material, such as. B. Quartz (Frechener Quarz), gravel (Weser gravel, Rhine gravel), basalt, marble, chippings, etc.



  introduced, e.g. B. rolled or vibrated.



   The thickness of the slurry that is applied depends on the shape and size of the grains selected, and is dimensioned so that about half of the smallest grain of the granular mineral material is embedded in the slurry. When using Frechener quartz of 8-10 mm grain, the application thickness of the sludge can advantageously be measured so that the grain is embedded approx. 4 mm deep.



   After the sludge has dried, which can be accelerated by heating the mold, the grain is firmly integrated into the mold. The mold is then expediently set vertically so that the excess grain is removed and therefore only the grain layer held by the sludge remains in the mold.



   On this facing layer, a plastic layer is applied, preferably in a horizontal position, preferably one from the group of thermosets, e.g. B. unsaturated polyester resins, epoxy resins, resins based on methyl methacrylate and the modifications of the aforementioned, advantageously in such a strength that the grain not embedded in the sludge is covered by the applied plastic layer and a flat surface is created.



   Anchors, Rabitz fabric or prefabricated elements made of concrete, lightweight concrete, aerated concrete, foam concrete, wood, metal, etc. can be inserted into the fresh plastic layer.



   After the plastic has hardened, the panel can be removed from the mold and the sludge is removed with water, so that the finished cladding panel is present.



   The particular advantages of the method according to the invention are that the panels produced in this way can have a lower weight and a lower thickness than the conventional exposed aggregate concrete panels, namely the corresponding values are only about 25% of those for the conventional exposed aggregate concrete panels. Furthermore, the panels produced according to the invention can be produced, for example, with high compressive and flexural strengths, great elasticity, absolute weather resistance and acid resistance and they also offer color design options.



   These properties result in numerous possible uses, some of which may be mentioned as examples.



   In the case of facade cladding, larger panels without special anchors in the mortar bed or with construction adhesive, e.g. B. a mixture of cement and quartz powder, or polyvinyl propionate in conjunction with methyl cellulose can be installed. Old buildings can be subsequently clad with special fastenings.



   Because of the high adhesive strength, the low weight and the absolute weather resistance of the panels according to the invention, prefabricated elements made of aerated concrete, foam concrete, expanded concrete, wood concrete, pumice concrete, slag concrete, brick gravel concrete and other lightweight and concrete elements can be connected to the plastic panels during production without special anchors.



   Due to the chemical resistance of the panels, they can be installed in operations such as slaughterhouses, fish factories, dairies, electroplating plants, etc. as non-slip and non-slip coverings.



   In addition, there are other possible uses, especially since the plastic can be adapted to a wide variety of needs in terms of its color and properties.
