Abstract
Description
Die Erfindung betrifft ein Verfahren zur Herstellung von Gipsfasermaterial aufweisenden gekrümmten flächigen Gestaltungselementen gemäß dem Oberbegriff des Pantentanspruchs 1.The invention relates to a method for producing curved flat design elements comprising gypsum fiber material according to the preamble of claim 1.
Bezweckt wird die Vereinfachung der Herstellung von flächigen Gestaltungselementen, insbesondere plattenförmigen Verkleidungen, die im Trockenbau montiert werden. Die Gestaltungselemente können konkave und/oder konvexe Flächen aufweisen, wie sie beispielsweise bei imitierten Gewölben oder anderweitig gekrümmten Wandverkleidungen vorkommen.The aim is to simplify the manufacture of flat design elements, in particular panel-shaped cladding, which are installed in drywall. The design elements can have concave and / or convex surfaces, such as occur, for example, in imitation vaults or otherwise curved wall claddings.
Aus der DE-OS 35 32 023 ist bereits ein Verfahren zum Einbauen imitierter Gewölbe oder anderweitig gekrümmter Wandverkleidungen in durch Wandungen anderer Form, insbesondere ebene Wandungen, begrenzte Räume, bekannt, wobei auf einem gerüstartigen Unterbau verformte Verkleidungselemente abschnittsweise angebracht werden. Die Verkleidungselemente bestehen aus gekrümmten Gipswandbauplatten mit Faserverstärkung, insbesondere aus Gipsfaser- oder Gipskartonplatten, die dadurch hergestellt worden sind, daß die im Handel erhältliche ebene Gipsbauplatte befeuchtet, dann vorgebogen und getrocknet wird, wonach dann aus der getrockneten gebogenen Platte die einzelnen gekrümmten Verkleidungsabschnitte entsprechend zugeschnitten werden.DE-OS 35 32 023 already describes a method for installing imitation vaults or otherwise curved wall cladding in walls of a different shape, in particular flat walls, limited spaces, known, whereby deformed cladding elements are attached in sections on a scaffold-like substructure. The cladding elements consist of curved gypsum wall building boards with fiber reinforcement, in particular of gypsum fiber or gypsum plasterboard, which have been produced by moistening the commercially available flat gypsum building board, then pre-bending and drying, after which the individual curved cladding sections are then cut from the dried curved board accordingly will.
Bei der Ausführung dieses vorbekannten Verfahrens hat sich herausgestellt, daß die Herstellung von genauen verformten Gipswandbauplatten im Hinblick auf eine dem vorgesehenen Einbauzweck genügende genaue Herstellung sowie der Verformung selbst recht zeitaufwendig, mühsam und gelegentlich fehlerbehaftet ist. Insbesondere das entsprechende passende Herstellen der gewünschten verformten Gipswandbauplatte aus einer bereits vorgeformten Ausgangsplatte läßt sich häufig nur unter Schwierigkeiten und dem Einsatz von speziellen Halte- und Schneideeinrichtungen realisieren. Auch die Übertragung der erforderlichen Maße des gewünschten gekrümmten Plattenabschnitts auf eine vorverformte Ausgangsplatte birgt zahlreiche Fehlermöglichkeiten, die zu unbrauchbaren Verkleidungsplatten oder zu aufwendigen manuellen Füllkorrekturen zwischen benachbarten gekrümmten Bauplatten führen. Ferner ist auch der bisher durchgeführte Verformungsvorgang für derartige Gipswandbauplatten insbesondere hinsichtlich der Dauer der Behandlung als auch der gewünschten Formhaltigkeit verbesserungsbedürftig.When carrying out this previously known method, it has been found that the production of precisely deformed plasterboard building boards is quite time-consuming, tedious and occasionally error-prone with regard to a precise production which meets the intended installation purpose and the deformation itself. In particular, the corresponding, suitable manufacture of the desired deformed gypsum plasterboard from an already preformed starting plate can often only be achieved with difficulty and with the use of special holding and cutting devices. The transfer of the required dimensions of the desired curved plate section to a pre-deformed starting plate also harbors numerous error possibilities which lead to unusable cladding plates or to complex manual filling corrections between adjacent curved building plates. Furthermore, the previously carried out deformation process for such gypsum wall building boards is in need of improvement, in particular with regard to the duration of the treatment and also the desired shape retention.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren der eingangs genannten Gattung derart weiterzubilden, daß individuell ausgebildete flächige Gestaltungselemente wirtschaftlich hergestellt werden können.The invention has for its object to develop a method of the type mentioned in such a way that individually designed flat design elements can be produced economically.
Erfindungsgemäß wird diese Aufgabe durch die im Patentanspruch 1 gekennzeichneten Merkmale gelöst.According to the invention, this object is achieved by the features characterized in claim 1.
Bevorzugte Merkmale, die die Erfindung vorteilhaft weiterbilden, sind in den nachgeordneten Patentansprüche genannt.Preferred features that advantageously further develop the invention are mentioned in the subordinate claims.
Aufgrund der erfindungsgemäßen Ausgestaltung der Erfindung lassen slch leicht und genau alle gekrümmte Flächen aufweisende Gestaltungselemente für Verkleidungszwecke wirtschaftlich herstellen. Aufgrund der Herstellungsgenauigkeit und problemlosen Durchführung des Verfahrens bietet dieses auch die Möglichkeit, nach einmaliger exakter Maßgabe identische Gestaltungselemente seriell zu fertigen und darüberhinaus auch standardisierte Baugrößen von derartigen Gestaltungselementen mit hoher Maßgenauigkeit herzustellen.On account of the configuration of the invention according to the invention, design elements for cladding purposes which have all curved surfaces can be easily and precisely produced economically. Because of the manufacturing accuracy and problem-free implementation of the method, this also offers the possibility of mass-producing identical design elements according to a one-off exact measure and, moreover, also of producing standardized sizes of such design elements with high dimensional accuracy.
Nach einer bevorzugten Ausgestaltung der Erfindung wird für die Darstellung der abgewickelten Fläche des herzustellenden Gestaltungselements ein maßstabsgerechtes Umsetzen von Maßangaben vorgenommen. Hierzu werden die benötigten Maße räumlich erfaßt und unter Berücksichtigung eines für die Projektion geeigneten Maßstabs berechnet, wobei die Darstellung der abgewickelten Fläche so durchgeführt wird, daß von der Darstellung ein Bild auf das unverformte flächige Gipsfasermaterial projiziert werden kann.According to a preferred embodiment of the invention, a true-to-scale conversion of dimensions is carried out for the representation of the developed surface of the design element to be produced. For this purpose, the required dimensions are spatially recorded and calculated taking into account a scale suitable for the projection, the representation of the developed area being carried out in such a way that an image of the representation can be projected onto the undeformed flat gypsum fiber material.
Die Darstellung der abgewickelten Fläche wird dabei so vorgenommen, daß ein 1:1-Bild der abgewickelten Fläche entweder im Auflicht-oder im Durchlichtverfahren auf das unverformte flächige Gipsfasermaterial projiziert werden kann. Vorzugsweise wird die Darstellung als Projektionsvorlage in Form eine Projektionsfolie hergestellt, die nach dem sogenannten "Overhead-Projektionsverfahren" mit hoher Abbildungsgenauigkeit übertragen werden kann.The development of the developed surface is carried out in such a way that a 1: 1 image of the developed surface can be projected onto the undeformed flat gypsum fiber material either by incident light or by transmitted light. The representation is preferably produced as a projection template in the form of a projection film which can be transmitted with high imaging accuracy using the so-called "overhead projection method".
Das vorgesehene Beschneiden des unverformten flächigen Gipsfasermaterials gemäß der darauf projizierten Fläche kann vorteilhaft unter Ausnutzung eines Helligkeits- und Farbkontrasts im Randbereich der aufprojizieten Fläche beschnitten werden. Gemäß einer vorteilhaften Weiterbildung der Erfindung wird vor dem Beschneiden des unverformten flächigen Gipsfasermaterials eine Kennzeichnung der Kontur der abgewickelten Fläche vorgenommen. Hierdurch läßt sich vorteilhaft der eigentliche Schneidevorgang von dem Aufprojektionsvorgang trennen. Außerdem bietet die Kennzeichnung der Kontur bzw. des Linienverlaufs des Umfangs der abgewickelten Fläche vorteilhaft die Möglichkeit, den Schneidevorgang durch Einsatz einer auf den Linienverlauf ansprechenden Steuereinrichtung zu automatisieren. Das Beschneiden des flächigen Gipsfasermaterials erfolgt dabei entweder in konventioneller Art mittels einer Sägeeinrichtung oder unter Verwendung eines Lasers.The intended trimming of the undeformed flat gypsum fiber material according to the surface projected thereon can advantageously be trimmed using a lightness and color contrast in the edge region of the projected surface. According to an advantageous development of the invention, a marking of the contour of the unwound surface is carried out prior to the trimming of the undeformed flat gypsum fiber material. In this way, the actual cutting process can advantageously be separated from the front projection process. In addition, the marking of the contour or the line profile of the circumference of the unwound surface advantageously offers the possibility of automating the cutting process by using a control device which responds to the line profile. The flat gypsum fiber material is trimmed either in a conventional manner using a sawing device or using a laser.
Nach Herstellung des Gestaltungselements in flächiger abgewickelter Form ist es vor einer Formgebung erforderlich, eine günstige Verformbarkeit des Gipsfasermaterials herbelzuführen. Falls das flächige Gipsfasermaterial herstellerseitig imprägniert ist, erfolgt zunächst eine Behandlung zur Beseitigung der Imprägnierung. Gleichzeitig oder anschließend an diese Behandlung wird dann ein Behandlung zur Verringerung des Härtezustandes durchgeführt. Dies erfolgt durch Zuführen von Feuchtigkeit. Beispielsweise kann das Bauelement durch Aufsprühen von Wasser oder Eintauchen in Wasser befeuchtet werden. Vorzugsweise erfolgt das Befeuchten mit Heißdampf, um eine möglichst rasche Durchfeuchtung zu erreichen, die für eine problemlose Verformungsbehandlung des Gipsfasermaterials benötigt wird. Dabei kann vorzugsweise im Zusammenhang mit dem Heißdampf ein Diffusionsbeschleunigerzusatz verwendet werden, der vorteilhaft zu einer schnelleren Leitung und Aufnahme von Feuchtigkeit in dem Gipsfasermaterial führt.After the design element has been produced in a flat, unwound form, it is necessary, before shaping, to bring about a favorable deformability of the gypsum fiber material. If the flat gypsum fiber material is impregnated by the manufacturer, treatment is first carried out to remove the impregnation. A treatment to reduce the hardness condition is then carried out simultaneously or after this treatment. This is done by adding moisture. For example, the component can be moistened by spraying water or immersing it in water. Humidification is preferably carried out with superheated steam in order to achieve the fastest possible moistening, which is required for problem-free deformation treatment of the gypsum fiber material. In this connection, a diffusion accelerator additive can preferably be used in connection with the superheated steam, which advantageously leads to faster conduction and absorption of moisture in the gypsum fiber material.
Für die Verformung des befeuchteten zugeschnittenen flächigen Gipsfasermaterials ist nach einer bevorzugten weiteren Ausgestaltung der Erfindung eine das Gestaltungselement von wenigstens eine Seite beaufschlagende Formpresse vorgesehen. Das Verformen des flächigen Gipsfasermaterials erfolgt vorteilhaft nach einem sogenannten Kaschier-Preßverfahren, bei dem das befeuchtete flächige Gipsfasermaterial zwischen zwei zu der endgültigen Form komplementären Gegenformen vorzugswelse mit Preßluft oder unter Verwendung von Unterdruck geformt wird.According to a preferred further embodiment of the invention, a shaping press acting on the design element from at least one side is provided for the deformation of the moistened cut flat gypsum fiber material. The shaping of the flat gypsum fiber material is advantageously carried out according to a so-called laminating press method, in which the moistened flat gypsum fiber material is preferably formed with compressed air or with the use of negative pressure between two counter-forms complementary to the final shape.
Zur Herstellung des ursprünglichen Härtegrades des Gipsfasermaterials wird das Gipsfasermaterial dann im verformten Zustand getrocknet. Dieses Trocknen kann beispielsweise konventionell durch Lufttrocknen oder in günstiger Weise durch Behelzen mit Feuchtigkeitsabfuhr innerhalb der Preßform erfolgen. Vorzugsweise wird dem in seine endgültige Gestalt geformten feuchten Gestaltungselement wenigstens Restfeuchtigkeit durch eine sogenannte Hochfrequenz-Trocknung oder nach einem Vakuumverfahren entzogen.The gypsum fiber material is then dried in the deformed state to produce the original degree of hardness of the gypsum fiber material. This drying can be carried out, for example, conventionally by air drying or in a favorable manner by treating with moisture removal within the mold. At least residual moisture is preferably removed from the moist design element shaped into its final shape by so-called high-frequency drying or by a vacuum process.
Für die Weitere Verwendung des getrockneten Gestaltungselements ist es im Hinblick auf dessen universelle Einsetzbarkeit für seine Formhaltigkeit von Vorteil, wenn eine Imprägnierung vorgesehen wird, wobei vorzugsweise ein Imprägniermittel auf Silikonbasis verwendet wird. Ein derartiges Imprägniermittel ist preiswert, farblos, umweltverträglich und ermöglicht eine problemlose Weiterbehandlung der Oberfläche des Gestaltungselements.For the further use of the dried design element, it is advantageous with regard to its universal applicability for its shape retention if an impregnation is provided, wherein preferably a silicone-based impregnation agent is used. An impregnating agent of this type is inexpensive, colorless, environmentally compatible and enables problem-free further treatment of the surface of the design element.
Als abschließende Behandlung des hergestellten Gestaltungselements kann weiterhin noch das Aufbringen von Farbe vorgesehen werden.As a final treatment of the design element produced, the application of color can also be provided.
