"Verfahren zur Herstellung von Verkleidungsplatten""Process for the production of cladding panels"

Die Erfindung "betrifft ein Verfahren zur Herstellung von Verkleidungsplatten für Wände, Böden, Fassaden o.dgl.The invention "relates to a method of manufacture of cladding panels for walls, floors, facades or the like.

Es ist bekannt, derartige Verkleidungen aus sog. Waschbetonplatten herzustellen, welche jedoch in ihren Einsatzmöglichkeiten wegen ihres vergleichsweise hohen Gewichtes und Materialaufwandes sowie ihren statischen Eigenschaften und ihrer Wetterbeständigkeit begrenzt sind.It is known to have claddings of this type made from so-called exposed aggregate concrete panels produce, which, however, in their possible applications because of their comparatively high weight and material costs as well as their static properties and their weather resistance are limited.

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

Gemäß der Erfindung wird dies dadurch erreicht, daß in eine Form eine wasserlösliche Schlämm· eingefüllt, und in diese ein für Waschbeton geeignetes Mineral eingebracht wird, worauf-According to the invention, this is achieved in that a water-soluble slurry is poured into a mold, and into this a mineral suitable for exposed aggregate concrete is introduced, whereupon-

hin nach Trocknung und Entfernen des überschüssigen Korns eine Kunststoffschicht aufgebracht wird, derart, daß die Körnung ganz eingebettet ist, und eine ebene ' Fläche entsteht, und nach Erhärten des Kunststoffes die Schlämme mit Wasser entfernt wird.after drying and removing the excess grain, a layer of plastic is applied in such a way that that the grain is completely embedded, and a flat 'surface is created, and after the plastic has hardened the sludge is removed with water.

Die Form wird zum Aufbringen der Schlämme waagerecht hingestellt, wobei die Formfläche aus Metall bestehen kann. Bei der Schlämme handelt es sich um eine schnelltrocknende, wasserlösliche Schlämme auf Silicatbasis (z.B. MC-Nafuplan-Formpaste Type Vie), die in gewünschter Stärke gleichmäßig aufgebracht wird.The mold is placed horizontally to apply the slurry, the mold surface being made of metal can. The sludge is a quick-drying, water-soluble silicate-based slurries (e.g. MC-Nafuplan-Formpaste Type Vie), which can be Strength is applied evenly.

In diese frische Schlamme wird ein für Waschbeton geeignetes Mineral (z.B. Frechener Quarz, Weserkies, Bheinkies, Basalt, Mamorsplitt usw.) eingestreut, eingewalzt oder eingerüttelt.In this fresh sludge, a concrete suitable for exposed aggregate becomes Mineral (e.g. Frechener quartz, Weser gravel, Bheink gravel, basalt, marble chippings, etc.) sprinkled in, rolled in or jogged.

Von der gewählten Form und Große des Minerals hängt die Auftragsdicke der Schlämme ab, und zwar ist diese derart, daß das kleinste Korn ca. zur Hälfte in diese einbettet wird, z.B. gewähltes Materials Frechener Quarz von 8 - 10 mm Korn, Auftragsdicke der Schlämme so, daß die Körnung ca. 4- mm tief eingebettet wird.It depends on the shape and size of the mineral chosen Application thickness of the sludge from, and this is such that the smallest grain embeds about half in it e.g. selected material Frechener quartz from 8 - 10 mm Grain, application thickness of the sludge so that the grain is embedded approx. 4 mm deep.

Nach Trocknen der Schlämme, was durch Beheizung der Form beschleunigt werden kann, ist das Korn fest in die Form eingebunden. Die Form wird dann senkrecht gestellt, damit das über-After the sludge has dried, which is accelerated by heating the mold the grain is firmly integrated into the mold. The form is then placed vertically so that the

schlissige Korn entfernt wird, und daher in der Form nur eine Kornschicht verbleibt.Schlissige grain is removed, and therefore only a grain layer remains in the mold.

Auf diese Vorsatsschicht wird in waagerechter Lage ein Kunststoffgemisch, vorzugsweise der Gruppe Duroplaste (z.B. IIC-Dur TJype Vie) in solcher Stärke aufgebracht, daß die Körnung ganz eingebettet ist, und eine ebene Fläche entsteht.A plastic mixture, preferably from the thermosetting group, is placed on top of this protective layer in a horizontal position (e.g. IIC-Dur TJype Vie) applied in such strength, that the grain is completely embedded, and a flat surface is created.

In der noch frischen Kunststoff schicht können Anker, Rabitzgewebe oder Fertigelemente aus Beton, Leichtbeton, Gasbeton, Schaumbeton, Holz, Metall usw., eingesetzt werden.Anchors, Rabitz mesh or prefabricated elements made of concrete, lightweight concrete, aerated concrete, foam concrete, wood, metal, etc., can be used.

Nach dem Erhärten des Kunststoffes wird die Platte aus der Form genommen, und die Schlämme mit Wasser entfernt« so daß die fertige Verkleidungsplatte vorliegt.After the plastic has hardened, the plate is made of the Taken the shape and removed the sludge with water so that the finished cladding panel is available.

Die besonderen Vorteile des erfindungsgemäfien Verfahrens bestehen darin,' daß die auf diese Weise hergestelltem Platten ein geringeres Gewicht und eine geringere Stärke besitzen, als die herkömmlichen Waschbetonplatten, und zwar beträgt diese nur etwa 25 Des weiteren verfugen die erfindungsgemäß hergestellten Platten über hohe Druck- und Biegezugfestigkeiten, große Elastizität, absolute Wetterbeständigkeit, Säurefestigkeit, farbige Gestaltungsmöglichkeitan usw.The particular advantages of the method according to the invention are that the panels produced in this way have a lower weight and thickness than the conventional exposed aggregate concrete panels, and this is only about 25%. Furthermore, the panels produced according to the invention have high pressure - and flexural strengths, great elasticity, absolute weather resistance, acid resistance, color design options, etc.

109810/0099109810/0099

Aufgrund dieser Eigenschaften ergeben sich, zahlreiche Verwendungsmöglichkeiten, von denen einige beispielsweise erwähnt sei.en.Because of these properties, there are numerous Uses, some of which are mentioned for example.

Bei der Passadenverkleidung können wegen des günstigen Gewichtes größere Platten ohne besondere Anker im Mörtelbett oder mit Baukleber (wie MO-Zentriefix BK) verlegt werden. Altbauten können mit besonderen Befestigungen nachträglich verkleidet werden.With the passage cladding can because of the favorable Larger weight slabs laid in the mortar bed without special anchors or with construction adhesive (such as MO-Zentriefix BK) will. Old buildings can be subsequently clad with special fastenings.

Vegen der hohen Klebkraft, des geringen Gewichtes und der absoluten Vetterbeständigkeit der erfindungsgemäßen Platten können Fertigteilelemente aus Gasbeton, Schaumbeton, Blähtonbeton, Holzbeton, Bimsbeton, Schlackenbeton, Ziegelsplittbeton und sonstige Leichtbau- und Betonelemente ι der FertigungBecause of the high adhesive strength, the low weight and the absolute cousin resistance of the boards according to the invention precast elements made of aerated concrete, foam concrete, expanded concrete, wood concrete, pumice concrete, slag concrete, brick gravel concrete and other lightweight and concrete elements ι the production

ohne besondere Verankerungen mit den Kunststoffplatten verbunden werden.connected to the plastic plates without any special anchoring will.

Aufgrund der chemischen Beständigkeit der Platten können diese in Betrieben, wie Schlachthäuser, Fischfabriken, Molkereien, galvanische Betriebe usw., als tritt- und rutschfeste Belege verlegt werden.Due to the chemical resistance of the plates they can in establishments such as slaughterhouses, fish factories, dairies, electroplating plants, etc., as a crush-resistant and slip-resistant documents are laid.

Darüber hinaus bestehen weitere Anwendungsmöglichkeiten, zumal der Kunststoff den verschiedensten Bedürfnisse* in seiner Farbgebung sowie in seinen Eigenschaften angepaßt werden kann. In addition, there are other possible uses, especially since the plastic can be adapted to the most diverse needs * in terms of its color and properties.
