Dünne Platten aus Marmor oder Alabaster dienten schon frühzeitig als eine Art 11Fensterscheibe".Appendix 2) Description of transparent panes made from synthetic resin Natural stone It is known that a number of natural stones, ground sufficiently thin, Let light penetrate to a muted degree. Thin slabs of marble or alabaster served as a kind of window pane early on.
Voraussetzung für die Anfertigung derart dünner Natursteinplatten ist makelloses Gesteinsmaterial, von großer Seltenheit. Wegen der Sprödigkeit und Brüchigkeit von Naturstein, können kaum größere Platten angefertigt werden.Requirement for the production of such thin natural stone slabs is flawless rock material, of great rarity. Because of the brittleness and Fragility of natural stone, it is hardly possible to make larger panels.
Es ist ferner bekannt, daß Naturgestein, in Form von Brocken, Körnungen, Schnittlingen(aus Brocken geschnittene, unregelmäßige Gesteinsplatten), qder Kieses mit Hilfe von-gebräuchlichen Kunstharzen, zu Blöcken oder Platten geformt werden können, die wiederum bearbeitbar sind durch Sägen, Fräsen, Schleifen, Polieren.It is also known that natural rock, in the form of chunks, grains, Cuttings (irregular slabs of stone cut from lumps), the gravel with the help of common synthetic resins, to be formed into blocks or plates can, which in turn can be machined by sawing, milling, grinding, polishing.
Erfindungsgegenstand sind Scheiben, hergestellt aus ausgesuchten, Lichtdurchlässigen Naturgesteinen, die in Form von Brocken, Körnungen, Schnittlingen oder Kiesel, mit Hilfe eines hochfesten, verwitterungsbeständigen Kunstharzes, derart miteinander verfestigt werden, daß-daraus Scheiben gesät und/oder geschliffen werden können, die, entsprechend dem ausge'suchten Naturstein, farbig abgewandeltes Licht durchscheinen lassen.The subject of the invention are disks made from selected, Translucent natural stones in the form of chunks, grains, cuttings or pebbles, with the help of a high-strength, weather-resistant synthetic resin, such are solidified with each other that-disks are sown and / or ground therefrom that, according to the selected natural stone, colored light let shine through.
Anwendungsbereich: "Verglasung" von sogenannten Ornamentbetonsteinen, transparente. bachabdeckungeF, durchleuchtete Tischplatten,und Theken, Beleuchtungskörper, transparente Trenn- und Dekorwände u.ä.Area of application: "Glazing" of so-called ornamental concrete blocks, transparent. bachabdeckungeF, illuminated table tops and counters, lighting fixtures, transparent partitions and decorative walls, etc.
Anlage 2) Beschreibung Transparente Scheiben aus kunstharzgebundenem Naturgestein Zu ihrer Fertigung werden Massen aus gebräuchlichen, hochfesten Kunstharzen einerseits und besonders ausgesuchten Natursteinkörnungen und -mehlen andererseits hergestellt.Appendix 2) Description of transparent panes made from synthetic resin Natural stone For their production, masses are made from common, high-strength synthetic resins on the one hand and specially selected natural stone grains and flours on the other manufactured.
Die Natursteinkörnungen und -mehle, von o-x mm, werden dabei so zusammengesetzt, daß sie eine weitgehende Dichtigkeit und Porenlosigkeit ergeben.The natural stone grains and flours, from o-x mm, are put together in such a way that that they result in a large degree of impermeability and porosity.
Als transparentes Naturgestein können dabei etwa folgende Gesteine verwendet werden: großkrisbZline Marmore, Onyx, Alabaster, Achat, Quarz, Kalkspat, Flußspat, Opal, Topas, Amethyst u.a.The following rocks can be used as transparent natural rock can be used: large-scale marbles, onyx, alabaster, agate, quartz, calcite, Fluorspar, opal, topaz, amethyst and others
Die erforderlichen Kunstharze sollen möglichst farblos, möglichst verwitterungsbeständig sein und hohe Festigkeiten ergeben. Es können u.a. dazu dienen: Polyesterharze, Styrol, Epoxydharze, Methacrylatharze. Letztere besitzen noch den Vorzug, niedrigviskos zu sein, was der Verdichtung dienlich ist und sind außerdem von einer ausgezeichneten Verwitterungsbeständigkeit.The synthetic resins required should be as colorless as possible, if possible be weather-resistant and result in high strengths. Among other things, it can serve to: Polyester resins, styrene, epoxy resins, methacrylate resins. The latter still have the Advantage of being of low viscosity, which is conducive to compaction and is also excellent weather resistance.
Die Massen werden in gebräuchlichen Rührwerken oder Mischer möglichst homogen gemischt und zum Polymerisieren bzw. Aushärten in geeignete Formen gegossen, die zur Herstellung von Blöcken oder Platten oder Hohlzylindern und dergleichen, äe nach gewünschter Form der Scheiben, dienen können.The masses are in common stirrers or mixers as possible mixed homogeneously and poured into suitable molds for polymerisation or hardening, those for the production of blocks or plates or hollow cylinders and the like, äe according to the desired shape of the slices, can serve.
Das Bormenmaterial muß ein leichtes Herauslösen der festgewordenen Massen garantieren. Eventuell sind j'rennmittel, wie Trennwachse, Trennöle, Folien, Überzüge un dergleichen zu verwenden.The Bormenmaterial must be an easy removal of the solidified Masses guarantee. Release agents such as release waxes, release oils, foils, To use coatings and the like.
Zur Erzielung einer weitgehenden Dichtigkeit und Porenlosigkeit, werden die Formen, während des Einfüllens und auch noch einige Zeit nachher, mit Hilfe von gebräucillichen Rüttelverfahren so stark bewehrt, daß eventuell vorhandenelLuftblasen entfernt werden.To achieve a high degree of impermeability and non-porosity, are the molds, during filling and for some time afterwards, with help so strongly reinforced by common vibration processes that air bubbles may be present removed.
Anlage 2) Beschreibung Transparente Scheiben au kunstharzgebundenem Naturgestein Die erstarrten Massen werden nach der Entfarmung, mitdiamantbesetzten Sägewerkzeugen und/oder Fräsen zu Scheiben in einer Stärke von 4-12 mm verarbeitet, die wiederum geschliffen und poliert bzw. mit Uberzügen versehen werden Eine andere Möglichkeit der Herstellung der erfindungsgemäßen Massen, ist die folgende: Es wird nach obigem Verfahren eine Grundmasse hergestellt, die beispielsweise Körnungen, der genannten Materialien von 0-7 mm enthält. Die Grundmasse wird in die Blockform gegossen..Appendix 2) Description of transparent panes made of synthetic resin Natural rock The solidified masses are set with diamonds after the disarming Sawing tools and / or milling machines processed into discs with a thickness of 4-12 mm, which in turn are ground and polished or provided with coatings. Another The possibility of producing the compositions according to the invention is as follows: It will using the above process, a base material is produced which, for example, contains grains, of the mentioned materials from 0-7 mm. The basic mass is in the block form poured ..
Vor Beginn der Aushärtung, werden nun Brocken beliebiger Größe, aus dem angeführten. Naturgestein8materital, in die Grundmasse eingerüttelt. - Weiteres Vorgehen, wie oben.Before the hardening begins, chunks of any size are made the cited. Natural rock material, vibrated into the base mass. - Additional Proceed as above.
Eine weitere Möglichkeit zur Herstellung der erfindungsgemäßen Scheiben, besteht in folgendem Verfahren: Es wird,wie vorher, eine Grundmasse hergestellt, die beispielsweise Körnungen des genannten Materials von o-3 mm enthält. Diese Grundmasse wird in Plattenformen gegossen, in die,vor oder nach dem Eingießen, größere Stücke des genannten Gesteins eingelegt werden.Another possibility for producing the disks according to the invention, consists of the following process: As before, a base mass is produced, which contains, for example, grain sizes of the material mentioned from o-3 mm. This basic mass is poured into plate molds, in which, before or after pouring, larger pieces of the rock mentioned.
Zum Einlegen sind geeignet: flache Gesteinsbrocken, natur- oder künstlich-gerundete -Kiesel, vorgeschnittene Gesteinsstücke(sogenannte Schnittlinge). Nach dem Aushärten werden diese Platten entweder gesägt (Parallel zu ihrer größten Fläche) oder nur beidseitig gefräst und/oder geschliffen, bis sie die erforderliche Stärke von 4-1-2 mm haben.Suitable for insertion are: flat rocks, naturally or artificially rounded - Pebbles, pre-cut pieces of rock (so-called cuttings). After hardening these panels are either sawn (parallel to their largest surface) or only Milled and / or sanded on both sides until they have the required thickness of 4-1-2 mm have.
Durch die genannten Verfahren, besonders aber durch das tetætere,"können bei entsprechder Auswahl verschieden farbiger Naturgesteine, evtl.in vorgegebenen Anordnungen,oder Farben, Scheiben erzeugt werden, die sich dadurch auszeichnen, daß dus hindurchscheinende Licht farbig effektvoll variiert wird.Through the procedures mentioned, but especially through the tetætere, "can with a corresponding selection of different colored natural stones, possibly in given ones Arrangements, or colors, panes are generated, which are characterized by that the light shining through is varied in color and effect.
