Description

Stand der TechnikState of the art

Die Erfindung geht aus von einem Verfahren zur Herstellung einer fugenlosen Duschplatte aus wasserdichtem Natur- oder Kunststein oder Keramik, die in Bädern oder als separater Duschplatz mit oder ohne Trägerkörper eingebaut wird. Einstückige Duschplatten gewährleisten nicht nur die Dichtheit des Duschplatzes, sondern geben Bädern außerdem ein exklusives Aussehen, insbesondere dann, wenn sie aus demselben Material wie der angrenzende Fußboden und in einer Ebene mit diesem eingebaut werden. Außerdem erfüllt ein stufenloser Übergang vom Badfußboden zum Duschbereich die Anforderungen eines barrierefreien Bades. Dabei kann die Duschplatte aus jedem beliebigen wasserdichten Naturmaterial, beispielsweise Natur- oder Kunststein, aber auch aus Keramik bestehen. Bekannt ist hierzu eine aus einem Boden mit umlaufenden Rand bestehende Duschtasse aus Naturstein, deren Bodenfläche eine vom Rand zum Wasserablauf abgestufte Oberfläche aufweist. Die abgestufte Oberfläche wird durch Fräsen eines zwei planparallele Ebenen aufweisenden Natursteinblocks hergestellt, wobei der Fräser je Treppenstufe in einer parallel zu den planparallelen Flächen verlaufenden Ebene geführt wird ( DE 195 41 692 A1 ). Der Nachteil dieser Duschtasse besteht darin, dass die abgestufte Bodenfläche, selbst wenn der Höhenunterschied von Stufe zu Stufe lediglich weniger als 1 mm beträgt, an den Füßen als störend empfunden wird. Auch rein optisch wirkt die Fläche nicht homogen, wodurch die Ästhetik des Duschplatzes beeinträchtigt ist. Ein weiterer Nachteil besteht darin, dass Wasser- und Schmutzreste auf den Stufen haften bleiben und sich eine gestufte Bodenfläche schwerer reinigen lässt als eine glatte Oberfläche. Nachteilig ist aber auch das aufwändige Bearbeitungsverfahren, bei dem der Fräser entsprechend der Anzahl der Stufen in unterschiedlich hohen Ebenen geführt werden muss.The invention relates to a method for producing a seamless shower plate made of waterproof natural or artificial stone or ceramic, which is installed in bathrooms or as a separate shower area with or without support body. One-piece shower trays not only ensure the tightness of the shower stall, but also give bathrooms an exclusive look, especially when installed in the same material as the adjoining floor and level therewith. In addition, a continuous transition from the bathroom floor to the shower area fulfills the requirements of a barrier-free bathroom. In this case, the shower plate from any waterproof natural material, such as natural or artificial stone, but also made of ceramic. Known for this purpose is an existing from a floor with peripheral edge shower tray made of natural stone, the bottom surface has a graduated from the edge to the water surface. The stepped surface is made by milling a natural stone block having two plane-parallel planes, the milling cutter depending Stair step is guided in a plane running parallel to the plane-parallel surfaces ( DE 195 41 692 A1 ). The disadvantage of this shower tray is that the stepped floor surface, even if the difference in height from level to level is only less than 1 mm, is felt to be disturbing on the feet. Also, purely visually, the surface is not homogeneous, whereby the aesthetics of the shower is impaired. Another disadvantage is that residues of water and dirt stick to the steps and a stepped floor surface is harder to clean than a smooth surface. However, a disadvantage is also the elaborate machining process, in which the milling cutter must be guided according to the number of stages in different levels.

Eine andere Duschtasse aus Naturstein besteht aus einem glattflächigen Boden mit einem umlaufenden Rand und einem Wasserablauf, wobei der Boden eine vom Rand zum Wasserablauf geneigte Oberfläche aufweist. Der Rand der Duschtasse ist flächenbündig mit dem angrenzenden Oberboden verbunden ( DE 201 17 836 U1 ). Der umlaufende Rand, der offensichtlich das Austreten von Wasser in den Bereich des Oberbodens verhindern soll, wirkt in zweierlei Hinsicht störend: Zum einen beeinträchtig er die ästhetische Gesamtwirkung der Duschtasse aus Naturstein, da er eine deutliche optische Unterbrechung zwischen Duschtasse und angrenzendem Oberboden darstellt, und zum andern wirkt die durch ihn gebildete Kante für den menschlichen Fuß störend bzw. kann für ihn mitunter eine nicht unerhebliche Verletzungsgefahr darstellen. Ferner ist das Zusammenfügen von Duschtasse und Oberboden mit einem zusätzlichen Aufwand verbunden.Another shower tray made of natural stone consists of a smooth-surfaced floor with a peripheral edge and a water outlet, the floor has a sloping from the edge to the water surface. The edge of the shower tray is flush with the adjacent upper floor ( DE 201 17 836 U1 ). The peripheral edge, which is apparently intended to prevent the escape of water in the area of the topsoil disturbing in two ways: First, it affects the overall aesthetic effect of the shower tray made of natural stone, as it represents a clear visual interruption between the shower tray and adjacent topsoil, and On the other hand, the edge formed by it interferes with the human foot or can sometimes pose a considerable risk of injury to him. Furthermore, the joining of shower tray and topsoil is associated with additional effort.

Bekannt ist ferner ein Verfahren zur Herstellung von Badeinrichtungen aus Holz, bei dem in einem ersten Verfahrensschritt Platten, die aus einer Vielzahl von gefügten Streifen bestehen, in überlappter Position gefügt werden. Die Achsen derselben verlaufen parallel oder senkrecht zur Längsfläche der Platten, so dass ein so gefertigter Ausgangskörper ausreichende Abmessungen und Gestalt aufweist, die der Gestalt der zugehörigen Badeinrichtung, die sie umfasst, entspricht. In einem zweiten Verfahrensschritt wird durch eine spanabhebende Bearbeitung die für den Ausgangskörpers vorgesehene Hohlform eingebracht. Die dreidimensionale Hohlform wird mittels einer CNC-Maschine, die durch ein Programm gesteuert ist, das die gewünschte Form der Einrichtung enthält, aus dem Ausgangskörper herausgearbeitet. ( WO 2004/043214 A )Also known is a method for the production of bath equipment made of wood, in which in a first process step plates, which consist of a plurality of joined strips are joined in an overlapped position. The axes thereof are parallel or perpendicular to the longitudinal surface of the plates, so that an output body made in this way has sufficient dimensions and shape which corresponds to the shape of the associated bathing device comprising it. In a second process step, the hollow mold provided for the starting body is introduced by machining. The three-dimensional mold is machined out of the starting body by means of a CNC machine controlled by a program containing the desired shape of the device. ( WO 2004/043214 A )

Schließlich ist ein Bodenelement einer Dusche zum Auffangen und Ableiten von Wasser bekannt, die als einstückige ebene und waagerechte Steinplatte ausgebildet ist und in stufenloser Fortsetzung an einen sich anschließenden Boden eingebaut ist. Zur Ableitung des Wassers sind von deren Rand ausgehende und zu einem in die Steinplatte eingearbeiteten Abfluss führende Nuten in die Steinplatte eingearbeitet ( EP 1 147 732 A2 ).Finally, a floor element of a shower for collecting and draining water is known, which is formed as a one-piece flat and horizontal flagstone and is installed in stepless continuation to a subsequent floor. To derive the water outgoing from the edge and leading to an incorporated into the stone plate drain grooves are incorporated into the stone plate ( EP 1 147 732 A2 ).

Die Erfindung und ihre VorteileThe invention and its advantages

Das erfindungsgemäße Verfahren mit den Merkmalen des Anspruchs 1 ist ein sehr komfortables Bearbeitungsverfahren, mit dem eine formvariable Oberflächengestalt des Duschbodens in einem ununterbrochenen Arbeitsgang erzielt werden kann. Die gewünschte Gestalt des Duschbodens, der die Ablauffläche für das Wasser bildet, wird in einem Datenverarbeitungsprogramm gespeichert, das beispielsweise eine CNC-Bearbeitungsmaschine steuert. Dadurch können aus edlen und daher teuren Natur- oder Kunststein, wie z. B. Marmor, Granit, Keramik o. ä., bestehenden Materialblöcken Duschplatten für exklusiv Bäder in jeder vom Kunden gewünschten Form, trotz dass es sich bei jeder Duschplatte im Wesentlichen um eine Einzelanfertigung handelt, verhältnismäßig preiswert hergestellt werden. Die Gestalt des Duschbodens betrifft dabei nicht nur die reine Gefällefläche, sondern auch deren Umfangsform, d. h. ihren Randbereich, an dem das Gefälle beginnt, sowie die Öffnung für den Wasserauslauf. Bei der Randgestaltung sind ebenfalls beliebige Formen denkbar. Die Ausarbeitung der Ablauffläche für die Wasserführung zum Auslauf hin erfolgt als beliebig gewölbte Flächen, abweichend von der üblichen, nach innen eben abfallenden Wasserführung.The inventive method with the features of claim 1 is a very comfortable processing method, with which a shape-variable surface shape of the shower base can be achieved in a continuous operation. The desired shape of the shower floor, which is the drainage area for the Water is stored in a data processing program that controls, for example, a CNC processing machine. This can be made of noble and therefore expensive natural or artificial stone, such. As marble, granite, ceramics o. Ä., Existing material blocks shower plates for exclusive bathrooms in any shape desired by the customer, despite that it is in each shower plate is essentially a custom-made, are made relatively inexpensive. The shape of the shower base affects not only the pure gradient surface, but also their peripheral shape, ie their edge region on which the slope begins, and the opening for the water outlet. When designing the border, any shapes are also conceivable. The elaboration of the drainage surface for the water supply to the outlet is carried out as arbitrarily curved surfaces, deviating from the usual, inwardly just sloping water supply.

Die Herstellung einer Duschplatte aus einem mittels abtragender Bearbeitungsverfahren gestaltbarem Natur- oder Kunststein oder Keramik hat darüber hinaus den Vorteil, dass der Übergang von den äußeren Kanten des Materialblocks zur Sichtfläche scharfkantig, also quasi linienförmig ausgebildet werden kann. Das ist die Voraussetzung dafür, dass der an die Duschplatte angrenzende Fußboden mit geringst möglicher Fugenbreite an die Duschplatte angeschlossen werden kann. Im Übrigen soll auch durch die Verwendung der Bezeichnung "Duschplatte" anstelle von "Duschtasse" verdeutlicht werden, dass es sich bei dieser Erfindung nicht um ein beckenförmiges Auffangbehältnis für das Duschwasser handelt, sondern um eine harmonisch in den Fußboden eines Bades integrierte Platte, die zusätzlich die Funktion des Wasserablaufs gewährleistet.The production of a shower plate made of a formable by means of abrading processing natural or artificial stone or ceramic also has the advantage that the transition from the outer edges of the block of material to the visible surface sharp, ie quasi linear can be formed. This is the prerequisite for connecting the floor adjacent to the shower panel to the shower panel with the smallest possible joint width. Incidentally, it should be clarified by the use of the term "shower plate" instead of "shower tray" that this invention is not a basin-shaped collecting container for the shower water, but a harmoniously integrated into the floor of a bath plate, in addition Ensures the function of the water drainage.

Nach einer vorteilhaften Ausgestaltung der Erfindung wird zunächst die Ablauffläche der Duschplatte hergestellt, wobei das Bearbeitungswerkzeug von deren oberen Rand weg bis zum tiefsten Punkt der Duschplatte und in umgekehrter Richtung bewegt wird. Immer dann, wenn sich das Bearbeitungswerkzeug auf den Rand der Duschplatte zubewegt, läuft es an der Oberfläche der Duschplatte aus, so dass von der Ablauffläche zum Rand der Duschplatte ein stufenfreier Übergang entsteht. Bei dieser Verfahrensweise bildet sich die Kontur der Ablauffläche sukzessive im Verlauf der Bearbeitung heraus. Auf diese Weise ist es möglich, die Ablauffläche gegenüber dem Randbereich der Duschplatte ohne einen störenden Absatz auch optisch hervorzuheben. Der absatzfreie Übergang von der Ablauffläche zum unbearbeiteten Randbereich ist insbesondere für den Bereich des Ein- und Ausstiegs der Duschplatte wichtig. Der Vorteil des absatzfreien Übergangs ist auch bei solchen Duschplatten gegeben, die keinen oder nur teilweise einen horizontalen Randbereich aufweisen, bei denen also der obere Rand der Ablauffläche zumindest teilweise gleichzeitig die Außenkante der Duschplatte bildet. Bei einer solchen Duschplatte schließen sich der obere Rand der Ablauffläche oder Teile von ihm ebenfalls ohne Absatz unmittelbar an den Fußboden an.According to an advantageous embodiment of the invention, the drainage surface of the shower plate is first prepared, wherein the machining tool is moved away from its upper edge to the lowest point of the shower plate and in the reverse direction. Whenever the processing tool moves towards the edge of the shower tray, it runs out on the surface of the shower tray, creating a step-free transition from the drainage surface to the edge of the shower tray. In this procedure, the contour of the drainage surface is formed successively in the course of processing. In this way, it is possible to visually highlight the drainage surface with respect to the edge region of the shower plate without a disturbing paragraph. The paragraph-free transition from the drainage surface to the untreated edge region is particularly important for the area of entry and exit of the shower plate. The advantage of the heel-free transition is also given in those shower trays that have no or only partially a horizontal edge region, in which therefore the upper edge of the drainage surface at least partially simultaneously forms the outer edge of the shower tray. In such a shower plate, the upper edge of the drainage surface or parts of it also close without paragraph directly to the floor.

Nach einer anderweitigen vorteilhaften Ausgestaltung der Erfindung wird nach der Herstellung des Materialblocks zunächst die Kontur des oberen Randes der Ablauffläche hergestellt. Es handelt sich um Materialblöcke, die zwei planparallele Flächen aufweisen. In dem Fall wird diese Randkontur eine geschlossene Horizontale beliebiger Form darstellen, von der das ebenfalls beliebig gestaltete Gefälle zur Ablauföffnung der Duschplatte hin führt. Der Beginn der Bearbeitung mit dieser Horizontalen vereinfacht die Programmierung des Bearbeitungsverfahrens.According to another advantageous embodiment of the invention, the contour of the upper edge of the drainage surface is first prepared after the production of the material block. These are blocks of material that have two plane-parallel surfaces. In that case, this edge contour will represent a closed horizontal of arbitrary shape, from which the likewise arbitrarily shaped gradient leads to the drainage opening of the shower tray. The beginning of the Machining with this horizontal simplifies the programming of the machining process.

Nach einer zusätzlichen vorteilhaften Ausgestaltung der Erfindung wird der an den unbearbeiteten Rand der Duschplatte angrenzende obere Rand der Ablauffläche angefast. Dadurch wird ein noch geschmeidigerer Übergang von der Ablauffläche zum Rand der Duschplatte hin erreicht. Dies ist besonders dann von Vorteil, wenn durch Dickentoleranzen des Materialblocks in diesem Übergangsbereich leichte Höhenunterschiede, die sich durchaus im Bereich von Zehnteln bis zu wenigen Millimetern bewegen können, auftreten. Diese Höhenunterschiede werden durch das Anfasen kaschiert.According to an additional advantageous embodiment of the invention adjacent to the unprocessed edge of the shower plate upper edge of the drainage surface is chamfered. This achieves an even smoother transition from the drainage surface to the edge of the shower tray. This is particularly advantageous if, due to thickness tolerances of the material block in this transition region slight differences in height, which can move quite in the range of tenths to a few millimeters occur. These height differences are masked by chamfering.

Nach einer zusätzlichen vorteilhaften Ausgestaltung der Erfindung ist die Herstellung der Ablauföffnung in das Bearbeitungsverfahren integriert. Bei der Herstellung eines verdeckten Auslaufs wird dann gleichzeitig noch die Ausarbeitung der Ausnehmung für die Abdeckung der Ablauföffnung in das Verfahren integriert. Dadurch entsteht die Duschplatte in einem ununterbrochenen Prozess. Diese Vorgehensweise ist auch deshalb vorteilhaft, weil in der Programmsteuerung ohnehin die Lage der Ablauföffnung als tiefster Punkt der Ablauffläche berücksichtigt werden muss.
Nach einer diesbezüglich vorteilhaften Ausgestaltung der Erfindung wird die Ablauföffnung nach der Fertigstellung der Ablauffläche an deren tiefsten Stelle ohne Unterbrechung des Bearbeitungsvorgangs in die Duschplatte eingebracht. Bei der Herstellung eines verdeckten Auslaufs wird dann gleichzeitig noch die Ausarbeitung der Ausnehmung für die Abdeckung des Auslaufs in das Verfahren integriert. Dadurch braucht das Bearbeitungswerkzeug den Materialblock lediglich noch an seiner dünnsten Stelle auszuarbeiten. Selbstverständlich ist es auch denkbar, zuerst die Öffnung für den Auslauf in den Materialblock einzubringen und anschließend die Ablauffläche zwischen dieser Öffnung und dem Rand auszuarbeiten.According to an additional advantageous embodiment of the invention, the production of the drain opening is integrated into the machining process. During the production of a concealed spout, the preparation of the recess for covering the drain opening is then integrated into the process at the same time. This creates the shower tray in an uninterrupted process. This procedure is also advantageous because in the program control anyway the position of the drain opening must be considered as the lowest point of the drainage area.
According to a related advantageous embodiment of the invention, the drain opening is introduced after the completion of the drainage surface at its lowest point without interruption of the machining process in the shower tray. In the production of a concealed spout then the preparation of the recess for the cover of the spout is then integrated into the process at the same time. As a result, the machining tool only needs the material block on its to work out the thinnest point. Of course, it is also conceivable to first introduce the opening for the outlet in the material block and then work out the drainage area between this opening and the edge.

Nach einer vorteilhaften Ausgestaltung der Erfindung werden die Ablauffläche und die Ablauföffnung durch 3-D-Fräsen aus dem Materialblock herausgearbeitet. Dieses Verfahren erlaubt eine schnelle Bearbeitung mit konventionellen Werkzeugen und Bearbeitungsmaschinen und ist daher besonders preisgünstig.According to an advantageous embodiment of the invention, the drainage surface and the drain opening are machined out of the block of material by 3-D milling. This method allows rapid processing with conventional tools and processing machines and is therefore particularly inexpensive.

Nach einer anderweitigen vorteilhaften Ausgestaltung der Erfindung wird die Ablauffläche der Duschplatte einer Finish-Bearbeitung unterzogen. So kann z. B. durch ein abschließendes Sandstrahlen je nach verwendeter Körnung eine Verfeinerung der Oberfläche oder eine Aufrauhung zur Verbesserung der Trittsicherheit erreicht werden. Auch die Einbringung von Mustern zur Verbesserung des ästhetischen Erscheinungsbildes ist auf diese Weise möglich.According to another advantageous embodiment of the invention, the drainage surface of the shower plate is subjected to a finish processing. So z. B. by a final sandblasting depending on the grain used a refinement of the surface or a roughening to improve slip resistance can be achieved. The introduction of patterns to improve the aesthetic appearance is possible in this way.

Eine nach dem erfindungsgemäßen Verfahren hergestellte Duschplatte zeichnet sich dadurch aus, dass der Übergang von der unbearbeiteten Randfläche des Grundkörpers zur bearbeiteten Ablauffläche zumindest in dem Bereich des Ausstiegs kontinuierlich, also ohne störende Absätze ausgebildet ist. Dadurch ist dieser Bereich für den menschlichen Fuß quasi nicht spürbar und birgt somit auch keine Verletzungsgefahr.A shower plate produced by the method according to the invention is characterized in that the transition from the unprocessed edge surface of the base body to the processed drainage surface is formed continuously, ie without disturbing shoulders, at least in the region of the exit. As a result, this area is virtually unnoticeable for the human foot and thus does not pose a risk of injury.

Nach einer diesbezüglich vorteilhaften Ausgestaltung der Erfindung ist der Übergang vom Randbereich in die Ablauffläche als eine die Ablauffläche als geschlossene Kontur umgebende, durchgehend bearbeitete Fläche ausgebildet. Dadurch wird die Umfangsform der Ablauffläche, so wie sie von der Programmierung her vorgesehen ist, besonders gut hervorgehoben, da dieser Randbereich unabhängig von Dickentoleranzen des Materialblocks durchgehend von dem Bearbeitungswerkzeug in seiner Oberflächenstruktur verändert wird. Da es sich bei den Dickentoleranzen in der Regel lediglich um wenige Zehntel bis ein Millimeter handelt, dürfte dadurch auch kein spürbarer Absatz entstehen. Die Herstellung dieses durchgehend bearbeiteten Randbereichs kann, wie in Anspruch 3 beschrieben, zu Beginn des Bearbeitungsverfahrens erfolgen. Dieser Randbereich hat neben seiner ästhetischen Wirkung aber noch eine wesentliche technische Funktion: da er eine rauhere Oberflächenstruktur als der angrenzende unbearbeitete Rand besitzt, unterbricht er gleichzeitig die Kapillarwirkung des Wasser und behindert dadurch den Wasserfluss nach außen.According to an advantageous embodiment of the invention, the transition from the edge region into the drainage surface is as surrounding the drainage surface as a closed contour, formed continuously machined surface. As a result, the peripheral shape of the drainage surface, as provided by the programming, is highlighted particularly well, since this edge region is continuously changed by the machining tool in its surface structure, regardless of thickness tolerances of the material block. Since the thickness tolerances are usually only a few tenths to a millimeter, this should also be no noticeable paragraph. The production of this continuously processed edge region can, as described in claim 3, take place at the beginning of the machining process. In addition to its aesthetic effect, this edge area still has an essential technical function: since it has a rougher surface structure than the adjacent untreated edge, it simultaneously interrupts the capillary action of the water and thus impedes the flow of water to the outside.

Beschreibung des AusführungsbeispielsDescription of the embodiment

Fig. 1 zeigt die Hauptteile eines Duschplatzes mit einer erfindungsgemäßen Duschplatte 1, zwei Wandplatten 2 und einer Unterbauplatte 3. Die erfindungsgemäße Duschplatte 1 ist bei dieser Variante quadratisch gestaltet und aus den Fig. 2 und 3 näher erkennbar. Ihre Oberfläche wird durch eine ununterbrochene, leicht konkave ausgearbeitete Ablauffläche 4 und einen diese umgebenden äußeren Rand 5 gebildet. Obwohl sie durch ein Material abtragendes Verfahren hergestellt ist, weist die Ablauffläche 4 keinerlei, also auch nicht durch ihre Herstellung bedingte, Kanten oder Absätze auf, so dass ihre Qualität bezüglich des haptischen Empfindens vom äußeren Rand bis zum Wasserablauf durchaus mit der glatten Oberfläche tiefgezogener oder gegossener Duschtassen vergleichbar ist. Wie aus Fig. 3 erkennbar, geht auch der äußere Rand 5 ohne Absatz oder Kante in die Ablauffläche 4 über. An ihrem tiefsten Punkt weist die Ablauffläche 4 eine Öffnung 6 zum Anschluss an die Entwässerung des Duschplatzes auf, wobei die Öffnung durch eine Abdeckung 7 verschließbar ist. Die Wandplatten 2 werden auf den äußeren Rand 5 der Duschplatte 1 aufgesetzt und gegenüber diesem und an ihren aneinander stoßenden Längskanten abgedichtet. Zur Aufnahme der Wandplatten 2 können in die Duschplatte 1 Nuten eingearbeitet sein. Im vorliegenden Beispiel sind allerdings nur Nuten 8 zur Aufnahme von den Duschplatz abschließenden Duschtrennwänden in den äußeren Rand 5 eingearbeitet. Fig. 1 shows the main parts of a shower area with a shower plate 1 according to the invention, two wall panels 2 and a base plate 3. The shower plate 1 according to the invention is designed square in this variant and from the FIGS. 2 and 3 closer recognizable. Its surface is formed by a continuous, slightly concave elaborated drainage surface 4 and a surrounding outer edge 5. Although made by a material-removing process, the drainage surface 4 has no, not even by their production conditional, edges or heels, so that their quality in terms of haptic sensation from the outer edge to the water outlet is quite comparable to the smooth surface of deep-drawn or cast shower bases. How out Fig. 3 recognizable, is also the outer edge 5 without paragraph or edge in the drainage surface 4 on. At its lowest point, the drainage surface 4 has an opening 6 for connection to the drainage of the shower area, wherein the opening can be closed by a cover 7. The wall panels 2 are placed on the outer edge 5 of the shower plate 1 and sealed against this and at their abutting longitudinal edges. To accommodate the wall panels 2 1 grooves can be incorporated into the shower tray. In the present example, however, only grooves 8 are incorporated to accommodate the shower enclosure final shower partitions in the outer edge 5.

Die Anordnung der Duschplatte 1 zu einem angrenzenden Fußboden 9 ist in Fig. 4 dargestellt. Zur Montage des Duschplatzes ist in dem Fußboden 9 eine den Abmessungen der Duschplatte 1 entsprechende Vertiefung vorgesehen, deren Tiefe, gemessen von der Oberkante des Fußbodens 9 bis zur Auflagefläche der Unterbauplatte 3, der Dicke von Duschplatte 1 und Unterbauplatte 3 entspricht, so dass die Oberfläche des Fußbodens 9 und des äußeren Randes 5 der Duschplatte 1 eine Ebene bilden.The arrangement of the shower plate 1 to an adjacent floor 9 is in Fig. 4 shown. For mounting the shower enclosure a corresponding dimensions of the shower plate 1 recess is provided in the floor 9, the depth, measured from the top of the floor 9 to the support surface of the base plate 3, the thickness of shower plate 1 and base plate 3 corresponds, so that the surface of the floor 9 and the outer edge 5 of the shower plate 1 form a plane.

Bei einem zweiten, in den Fig. 5 bis 7 dargestellten Ausführungsbeispiel wird ein Duschplatz mit einer Duschplatte 10 beschrieben, deren Ablauffläche 11 leicht konvex gewölbt ist, d. h. dass sich in ihrer Mitte der höchste Punkt befindet. Das Gefälle der Auflauffläche 11 führt zu einer in dem Außenrand 12 der Duschplatte 10 umlaufenden Ablaufrinne 13, die wiederum ein Gefälle zu einer sinnvollerweise am Rand der Duschplatte 10 angeordneten Ablauföffnung 14 hin aufweist. Das Gefälle ist jeweils durch Pfeile gekennzeichnet. In der in Fig. 7 gezeigten Draufsicht auf die Duschplatte 10 sind auch die beiden Nuten 8 zur Aufnahme von Duschtrennwänden erkennbar.At a second, in the Fig. 5 to 7 illustrated embodiment, a shower room is described with a shower plate 10, the drain surface 11 is slightly convex, ie that is in its center the highest point. The slope of the ramp surface 11 leads to a circumferential in the outer edge 12 of the shower tray 10 gutter 13, which in turn Slope to a meaningfully arranged on the edge of the shower plate 10 arranged drain opening 14 out. The gradient is indicated by arrows. In the in Fig. 7 shown top view of the shower plate 10, the two grooves 8 for receiving shower partitions are recognizable.

In Fig. 8 ist eine Duschplatte 15 mit rechteckiger Grundform dargestellt, bei der zusätzlich zu einer Ablauföffnung 16 eine umlaufende Überlaufrinne 17 in den äußeren Rand eingearbeitet ist. Diese kann bis zu einem Millimeter tief sein und dient dazu, den Wasserfluss zum äußeren Rand hin zu unterbrechen.In Fig. 8 is a shower plate 15 shown with a rectangular basic shape, in which in addition to a drain opening 16, a circumferential overflow channel 17 is incorporated in the outer edge. This can be up to a millimeter deep and serves to interrupt the flow of water to the outer edge.

Die Fig. 9 bis 14 sollen die Vielfalt der Gestaltungsmöglichkeiten von Duschplatten durch das erfindungsgemäße Bearbeitungsverfahren zeigen. In Fig. 9 sind neun Duschplatten mit einer rechteckigen äußeren Form und Entwässerung nach innen dargestellt, wobei die Ablaufflächen eine beliebig unterschiedliche äußere Begrenzung aufweisen und die Öffnung für die Entwässerung an beliebigen Stellen der Duschplatte angeordnet sind. Die sich dadurch ergebenden unterschiedlich konkav geformten Ablaufflächen können durch das erfindungsgemäße Bearbeitungsverfahren ohne großen Aufwand hergestellt werden, ohne dass spürbare Kanten entstehen. Selbst die äußere Begrenzung der Ablauffläche, die in allen Figuren zur Verdeutlichung der Form durch eine geschlossene Line dargestellt ist, ist beim Betreten der Duschplatte nicht spürbar, sondern lediglich durch die unterschiedliche Oberflächenstruktur von horizontalem äußeren Rand und Ablauffläche erkennbar, die durch eine unterschiedliche Bearbeitung entsteht. Fig. 10 zeigt eine von zwei Personen gleichzeitig nutzbare Doppelduschplatte 18 mit zwei Ablauföffnungen 16, wobei die Ablauffläche 19 vorne und hinten mit unterschiedlichen Radien 20 versehen ist.The Fig. 9 to 14 should show the variety of design options of shower trays by the processing method according to the invention. In Fig. 9 nine shower plates are shown with a rectangular outer shape and drainage inwards, wherein the drainage surfaces have an arbitrarily different outer boundary and the opening for the drainage are arranged anywhere on the shower plate. The resulting differently concave shaped run-off surfaces can be produced by the inventive processing method without great effort, without noticeable edges. Even the outer boundary of the drainage surface, which is represented in all figures to illustrate the shape by a closed line, is not noticeable when entering the shower plate, but only recognizable by the different surface structure of the horizontal outer edge and drainage surface, which results from a different processing , Fig. 10 shows one of two people simultaneously usable double shower plate 18 with two Drain openings 16, wherein the drainage surface 19 is provided at the front and rear with different radii 20.

Eine außen in Form einer Schnecke gestaltete Duschplatte 21 ist in Fig. 11 dargestellt. Sie besteht aus einem ebenen Teil 22, der die Form eines Viertelkreises aufweist, und einem Gefälleteil 23, in dem sich auch die Ablauföffnung 16 befindet. Der ebene Teil 22 kann als Einstiegsbereich der Dusche gestaltet sein. Das Gefälle beginnt ohne einen ebenen Randbereich unmittelbar an der runden äußeren Kante der Duschplatte 21. Die Montage einer solchen Duschplatte erfordert allerdings einen höheren Aufwand bei der Gestaltung des angrenzenden Fußbodens, der der schneckenförmigen Gestalt der Duschplatte 21 angepasst werden muss. Selbstverständlich ist es auch möglich, eine solche Duschplatte als quaderförmige Platte herzustellen und die schneckenförmige Gestalt des Gefälleteils 23 mittels des erfindungsgemäßen Verfahrens aus der Platte herauszuarbeiten, so dass der obere Rand des Gefälleteils 23 stufenlos in eine ebene, ggf. unbearbeitete Randfläche übergeht.An outside in the form of a screw designed shower plate 21 is in Fig. 11 shown. It consists of a flat part 22, which has the shape of a quarter circle, and a slope part 23, in which the drain opening 16 is located. The flat part 22 may be designed as an entry area of the shower. The slope begins without a flat edge region directly to the round outer edge of the shower plate 21. However, the installation of such a shower plate requires more effort in the design of the adjacent floor, which must be adapted to the helical shape of the shower plate 21. Of course, it is also possible to produce such a shower plate as a cuboid plate and herauszuarbeiten the helical shape of the slope portion 23 by means of the method of the invention from the plate, so that the upper edge of the slope portion 23 passes smoothly into a flat, possibly unprocessed edge surface.

In Fig. 12 ist wiederum eine Duschplatte 24 mit einer rechteckigen äußeren Form gezeigt. Ihre Ablauffläche 25 folgt im Wesentlichen der äußeren Form. Lediglich im Einstiegsbereich der Dusche ist rechts und links ein breiterer ebener Randbereich 26 vorgesehen. In der Ablauffläche 25 ist eine längliche Ablauföffnung 27 angeordnet. Eine solche Duschplatte 24 kann ebenfalls von zwei Personen gleichzeitig benutzt werden.In Fig. 12 Again, a shower plate 24 is shown with a rectangular outer shape. Its drainage surface 25 essentially follows the outer shape. Only in the entry area of the shower, a wider, flat edge region 26 is provided on the right and left. In the drainage surface 25, an elongated drain opening 27 is arranged. Such a shower plate 24 can also be used by two people at the same time.

Die Fig. 13 und 14 zeigen zwei Duschplatten 28 und 29 mit einer durch Kreisbogen begrenzten Ablauffläche 30, wobei die Duschplatte 28 eine elliptische Ablauföffnung 31 und die Duschplatte 29 eine längliche geschwungene Ablauföffnung 32 aufweist.The FIGS. 13 and 14 show two shower trays 28 and 29 with a circular arc limited drainage surface 30, wherein the shower plate 28 has an elliptical drain opening 31 and the Shower plate 29 has an elongated curved drain opening 32.
