Description

Die Anmeldung betrifft ein aus einem Gemisch von Fasern und einem Bindemittel gepreßtes langgestrecktes, an der einen Längskante mit einer Nut und an der anderen Längskante mit einem Federprofil versehenes Verkleidungsprofil, insbesondere zur Verkleidung von Gebäudefassaden.The application relates to an elongated cladding profile pressed from a mixture of fibers and a binder, provided on one longitudinal edge with a groove and on the other longitudinal edge with a tongue profile, in particular for cladding building facades.

Ein solches Verkleidungsprofil ist bekannt ( DE - A - 25 30 263). Bei dem span- oder faserförmigen Gemisch kann es sich beispielsweise um ein nicht steigfähiges Gemisch aus zerkleinerten lignozellulosehaltigen Teilchen, wie zerkleinerten und getrockneten Holzspänen, Bagassefasern u. ä. , handeln, denen ein wärmehärtbares Bindemittel auf Duroplast - Basis, wie ein Melamin - Harnstofformaldehyd- oder Phenolformaldehydharz, beigemischt ist. Anstelle der zerkleinerten und getrockneten Holz- oder Bagassefasern können auch Fasern anderer Werkstoffe, wie Glasfasern, Steinwolle oder Asbestfasern, allein oder mehrere derselben miteinander gemischt, verwendet werden, denen entsprechende, vorzugsweise organische, Bindemittel zugesetzt sind.Such a cladding profile is known (DE - A - 25 30 263). The chip or fibrous mixture can be, for example, a non-rising mixture of comminuted lignocellulosic particles, such as comminuted and dried wood shavings, bagasse fibers and the like. Act., act, which is a thermosetting binder based on thermoset, such as a melamine - urea formaldehyde or phenol formaldehyde resin, is admixed. Instead of the shredded and dried wood or bagasse fibers, fibers of other materials, such as glass fibers, rock wool or asbestos fibers, alone or several of them mixed with one another, to which appropriate, preferably organic, binders have been added can also be used.

Aus einem solchen Gemisch können Profilkörper, wie Tischplatten, Fensterbänke, Paletten und dgl. in der Weise hergestellt werden, daß das nicht steigfähige Gemisch je nach Form oder gewünschten Eigenschaften der fertigen Profilkörpers entweder in einer möglichst gleichmäßig starken oder an bestimmten Stellen bewußt unterschiedlichen Schichtdicke in ein Pressenunterteil eingefüllt wird. Dabei beträgt die Schichtdicke des Gemisches in dem Pressenunterteil üblicherweise das Vierbis Siebenfache des fertigen Profilkörpers. Wenn es sich bei der Presse um eine Vorpresse handelt, dann wird das in das Pressenunterteil eingefüllte Gemisch dort durch Einfahren eines Preßstempels ( Pressenoberteil ) vorgepreßt und dabei nahezu auf sein Endmaß verdichtet. Die Festigkeit des derart hergestellten Vorpreßlings reicht aus, um ein Verformen oder Zerbrechen beim Herausnehmen aus der Vorpresse zu verhindern. Er wird sodann , ggf. unter gleichzeitiger Bedeckung mit einer Deckschicht, in eine Heißpresse eingesetzt, wo der Vorpreßling unter Einwirkung von Druck und Wärme seine endgültige Form erhält, dabei aushärtet und ggf. gleichzeitig mit einer Deckschicht umhüllt wird.Profile bodies such as table tops, window sills, pallets and the like can be produced from such a mixture in such a way that the non-rising mixture, depending on the shape or desired properties of the finished profile body is filled into a lower press part either in a layer thickness that is as uniformly thick as possible or deliberately different at certain points. The layer thickness of the mixture in the lower press part is usually four to seven times the finished profile body. If the press is a pre-press, the mixture filled into the lower part of the press is pre-pressed there by moving in a press ram (upper part of the press) and almost compressed to its final dimensions. The strength of the preform thus produced is sufficient to prevent it from deforming or breaking when it is removed from the prepress. It is then placed, possibly under simultaneous covering with a covering layer, in a hot press, where the pre-compact obtains its final shape under the action of pressure and heat, thereby curing and possibly being simultaneously covered with a covering layer.

Die bekannten Verkleidungsprofile haben sich zwar in großem Umfang bewährt, sie sind jedoch je nach vorgesehenem Einsatzzweck und Einsatzort noch verbesserungsfähig. Wenn aus den bekannten Verkleidungsprofilen waagerecht verlegte Außenwandverkleidungen hergestellt werden, dann ergeben sich rinnenförmige Vertiefungen, in denen sich bei ungünstigen Klima oder ungünstigen Witterungsverhältnissen Feuchtigkeit, Schmutz und dgl. ablagern und einen vorzeitigen Verschleiß herbeiführen können.The known cladding profiles have proven themselves on a large scale, but they can still be improved depending on the intended use and location. If horizontally installed outer wall claddings are produced from the known cladding profiles, then there are trough-shaped depressions in which moisture, dirt and the like can be deposited in unfavorable climates or unfavorable weather conditions and can cause premature wear.

Es ist ein aus einem Gemisch von Fasern und Bindemitteln gepreßtes Verkleidungsprofil für Gebäude bekannt ( EP - A - 0 082 887 ), dessen Oberfläche in regelmäßigen Abständen mit parallel zur Breite des Verkleidungsprofils verlaufenden Nuten versehen ist. Damit das Verkleidungsprofil gerade und eben ist, sind auf seiner Rückseite Gegennuten angeordnet, welche parallel und symmetrisch zu beiden Seiten der auf die Rückseite projezierten Nut liegen.A cladding profile for buildings, which is pressed from a mixture of fibers and binders, is known (EP-A-0 082 887), the surface of which is provided at regular intervals with grooves running parallel to the width of the cladding profile. So that the cladding profile is straight and level, counter grooves are arranged on its back, which are parallel and symmetrical to both sides of the groove projected onto the back.

Es ist weiterhin eine Preßform zur Herstellung von ausgehärteten Formpreßkörpern aus dem gleichen Gemisch bekannt ( DE - A - 1 198 994 ) , mit welcher beim Pressen gleichzeitig in einer Stirnfläche eine Nut erzeugt werden soll. Zu diesem Zweck ist die Preßform mit einem federnd gelagerten, höhenbeweglichen Seitenstempel versehen.A press mold for the production of cured molded articles from the same mixture is also known (DE-A-1 198 994), with which a groove is to be produced simultaneously in one end face during pressing. For this purpose, the mold is provided with a spring-loaded, vertically movable side stamp.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Verkleidungsprofil zu schaffen, das überwiegend glatt und eben aufgebaut ist, welches in einfacher Weise in der Art einer Stülpschalung verlegt werden kann und an dem mechanisch und klimatisch besonders stark beanspruchte Teile auch entsprechend widerstandsfähig ausgebildet sind.The invention is therefore based on the object of providing a cladding profile which is predominantly smooth and level, which can be laid in a simple manner in the manner of a slip formwork and on which parts which are particularly stressed mechanically and in terms of climate are also designed to be correspondingly resistant.

Diese Aufgabe ist erfindungsgemäß dadurch gelöst, daß das Verkleidungsprofil eine von der einen zur anderen Längskante im Wesentlichen stetig zunehmende Wandstärke aufweist, an der Längskante mit der größeren Wandstärke eine höhere Dichte aufweist als an der Längskante mit der kleineren Wandstärke und wenigstens auf der nach der Verlegung sichtbaren Oberfläche mit einer festhaftenden Schutzschicht versehen ist.This object is achieved according to the invention in that the cladding profile has a wall thickness that increases substantially continuously from one to the other longitudinal edge, has a higher density on the longitudinal edge with the greater wall thickness than on the longitudinal edge with the smaller wall thickness and at least on that after installation visible surface is provided with a firmly adhering protective layer.

Die zunehmende Wandstärke des Verkleidungsprofils gestattet die einfache waagerechte Verlegung in der Art der Stülpschalung. Da die eine größere Wandstärke aufweisende Längskante eine höhere Dichte aufweist, ist sie im Zusammenwirken mit der festhaftenden witterungsbeständigen Schutzschicht besonders gegen ungünstige klimatische und mechanische Beanspruchungen widerstandsfähig.The increasing wall thickness of the cladding profile allows easy horizontal laying in the form of the slip formwork. Since the longitudinal edge, which has a greater wall thickness, has a higher density, it is particularly resistant to unfavorable climatic and mechanical loads in combination with the firmly adhering weather-resistant protective layer.

Für die Herstellung des Verkleidungsprofils hat sich eine Vorrichtung als vorteilhaft erwiesen mit einer Vorpresse, bestehend aus einem Pressenunterteil mit einem von innen nach außen schräg verlaufenden Boden und einem diesen umgebenden und mit diesem einen Kasten bildenden absenkbaren Rahmen, sowie einem Pressenoberteil, dessen dem Pressenunterteil zugewandte Oberfläche ebenfalls von innen nach außen schräg verlaufend ausgebildet und an der Außenkante mit einer Verdickung versehen ist, und einer Heißpresse, bestehend aus einem Pressenunterteil mit von außen nach innen verlaufendem Boden und einer Verdickung an der Außenkante sowie einem Pressenoberteil mit in gleicher Weise wie der Boden des Pressenunterteils schräg verlaufender Preßfläche.For the production of the cladding profile, a device has proven to be advantageous with a pre-press, consisting of a press lower part with a bottom that slopes obliquely from the inside out and a lowerable frame surrounding it and forming a box with it, and a press upper part, the part of which presses toward the press lower part Surface is also inclined from the inside to the outside and is provided with a thickening on the outer edge, and a hot press, consisting of a press lower part with a bottom extending from the outside inwards and a thickening on the outer edge and a press upper part with in the same way as the bottom of the lower press part of the press surface.

Die Vorrichtung kann für die Herstellung jeweils eines einzelnen langgestreckten Verkleidungsprofils ausgestaltet sei. Vorteilhafter ist es jedoch, wenn sie für die gleichzeitige Herstellung von jeweils zwei Verkleidungsprofilen ausgestaltet ist, d.h. aus einer Doppel - Vorpresse und einer Doppel - Heißpresse besteht, welche aus der spiegelbildlichen Anordnung zweier Vor - und Heißpressen zusammengesetzt sind.The device can be designed for the production of a single elongated cladding profile. However, it is more advantageous if it is designed for the simultaneous production of two cladding profiles, ie consists of a double pre - press and a double hot press, which are composed of the mirror image arrangement of two pre and hot presses.

Die Herstellung des Verkleidungsprofils erfolgt dadurch, daß das Gemisch erst in der Weise in das Pressenunterteil der Vorpresse eingefüllt wird, daß es eine ebene Oberfläche bildet, und dann das Pressenoberteil abgesenkt und das Gemisch dabei nahezu auf seine Enddichte verdichtet wird, daß dann der Vorpreßling aus der Vorpresse entnommen und nach einer Drehung um 180 Winkelgrade um seine Längsachse in das Pressenunterteil der Heißpresse eingelegt, auf seine Oberfläche die Schutzschicht aufgelegt und nach Absenken des Pressenoberteils der Heißpresse und Zuführung von Wärme fertiggepreßt wird.The cladding profile is produced by first filling the mixture into the lower press part of the pre-press in such a way that it forms a flat surface, and then lowering the upper press part and thereby compressing the mixture almost to its final density, so that the pre-compact is then made removed from the pre-press and, after rotating through 180 degrees about its longitudinal axis, placed in the lower press part of the hot press, the protective layer is placed on its surface and, after lowering the upper press part of the hot press and applying heat, it is pressed.

Wie aus Fig. 1 zu erkennen, weist das Verkleidungsprofil 1 eine solche Gestalt auf, daß die Wandstärke an der in Fig. 1 unteren Längskante 2 größer als an der - in Fig. 1 oberen - Längskante 3 des Verkleidungsprofils 1 ist. Die untere Längskante 2 besitzt eine Hinterschneidung und eine Nut , in welche bei den verlegten Verkleidungsprofilen die im Querschnitt nasenförmige Kante 4 der oberen Längskante 3 eintaucht. An der oberen Längskante 3 sind eine größere Anzahl von Befestigungslöchern vorgesehen. Mit diese durchdringenden Nägeln oder Schrauben sind die Verkleidungsprofile auf einer Unterlage, z. B. einer Hauswand oder einer auf der Hauswand befestigten Lattung, befestigt. Da die Längskanten 2 und 3 stärker als das übrige Volumen des Verkleidungsprofils belastet werden, sollte das Verkleidungsprofil dort eine höhere Verdichtung als das übrige Volumen des Verkleidungsprofils aufweisen.As can be seen from FIG. 1, the cladding profile 1 has such a shape that the wall thickness at the lower longitudinal edge 2 in FIG. 1 is greater than at the - in FIG. 1 upper - longitudinal edge 3 of the cladding profile 1. The lower longitudinal edge 2 has an undercut and a groove into which the cross-sectionally nose-shaped edge 4 of the upper longitudinal edge 3 is immersed in the installed cladding profiles. A larger number of fastening holes are provided on the upper longitudinal edge 3. With these penetrating nails or screws, the cladding profiles are on a base, for. B. a house wall or battens attached to the house wall. Since the longitudinal edges 2 and 3 are loaded more than the remaining volume of the cladding profile, the cladding profile there should have a higher compression than the remaining volume of the cladding profile.

Das aus Fig. 2 ersichtliche Pressenunterteil der Vorpresse besitzt ein feststehendes Mittelteil 5 und einen diesen umgebenden Rahmen 6, welcher um eine bestimmte Strecke heb- und senkbar ausgebildet ist. Die aus Fig. 2 ersichtliche Stellung des Rahmens 6 entspricht dem nicht abgesenkten Zustand. Mittelteil 5 und Rahmen 6 bilden einen Füllraum, in den das zu pressenden Gemisch bis zur ebenen Linie 7 eingefüllt wird . Der von der Oberfläche des Mittelteils 5 gebildete Boden 8 weist einen schrägen Verlauf auf , so daß der Füllraum am linken Rand eine größere Menge des Gemischs aufzunehmen vermag als in der Mitte.The lower part of the pre-press shown in FIG. 2 has a fixed middle part 5 and a frame 6 surrounding it, which is designed to be raised and lowered by a certain distance. The position of the frame 6 shown in FIG. 2 corresponds to the non-lowered state. Middle part 5 and frame 6 form a filling space into which the mixture to be pressed is filled up to the flat line 7. The bottom 8 formed by the surface of the middle part 5 has an oblique course, so that the filling space on the left edge is able to hold a larger amount of the mixture than in the middle.

Die Vorpresse gemäß den Figuren 2 und 3 sowie die Heißpresse gemäß Fig. 4 sind derart gestaltet, daß zwei Verkleidungsprofile gleichzeitig gepreßt werden können. Wenn mit der Presse einzelne Verkleidungsprofile gepreßt werden sollten, dann wäre nur eine Hälfte des Mittelteils erforderlich.The preliminary press according to FIGS. 2 and 3 and the hot press according to FIG. 4 are designed in such a way that two cladding profiles can be pressed simultaneously. If individual cladding profiles were to be pressed with the press, then only half of the middle part would be required.

Bei der in Fig. 3 dargestellten Vorpresse ist der Füllraum mit dem Gemisch gefüllt und das Pressenoberteil 9 ist aufgesetzt. Die dem Füllraum zugewandte Oberfläche des Pressenoberteils 9 ist an der Außenkante am Rahmen 6 - das ist dort, wo das Verkleidungsprofil eine höhere Verdichtung erhalten soll - mit einer Verdickung 10 versehen. Wenn nun auf das Pressenoberteil 9 eine senkrechte Kraft augeübt wird, dann bewegt es sich zusammen mit dem Rahmen 6 so lange nach unten, bis der Rahmen 6 auf den Stützen 17 aufsitzt. Dabei wird das Gemisch verdichtet und zwar an den Außenkanten wesentlich stärker als in der Mitte, weil im Bereich der Außenkanten eine größere Menge des Gemischs vorhanden war und wegen der Verdickung 10.In the pre-press shown in FIG. 3, the filling space is filled with the mixture and the upper press part 9 is attached. The surface of the press upper part 9 facing the filling space is provided with a thickening 10 on the outer edge on the frame 6 - this is where the cladding profile is to be given a higher compression. If a vertical force is now exerted on the upper press part 9, then it moves down together with the frame 6 until the frame 6 is seated on the supports 17. In the process, the mixture is compressed, and in fact much more strongly at the outer edges than in the middle, because a larger amount of the mixture was present in the region of the outer edges and because of the thickening 10.

Nach dem Preßvorgang werden der Rahmen 6 und das Pressenoberteil 9 wieder in die aus Fig. 3 ersichtliche Lage zurückgebracht. Der Vorpreßling wird aus der Vorpresse entnommen, um 180 Winkelgrade um seine Längsachse gedreht und in eine Heißpresse eingelegt.After the pressing process, the frame 6 and the upper press part 9 are brought back into the position shown in FIG. 3. The pre-compact is removed from the pre-press, rotated by 180 degrees about its longitudinal axis and placed in a hot press.

Die Heißpresse mit dem Pressenoberteil 11 und dem Pressenunterteil 12 ist in geschlossenem Zustand in Fig. 4 gezeigt. Bevor der Vorpreßling in die Heißpresse eingelegt wird, wird auf seine innere und äußere Oberfläche wenigstens eine Grundierfolie aufgelegt, welche beim Heißpressen fließt und sich fest mit dem Verkleidungsprofil verbindet.The hot press with the upper press part 11 and the lower press part 12 is shown in the closed state in FIG. 4. Before the pre-compact is placed in the hot press, at least one primer film is placed on its inner and outer surface, which flows during hot pressing and connects firmly to the cladding profile.

In Fig. 5 ist das linke Ende der Heißpresse deutlicher als in Fig. 4 dargestellt. Es ist besonders darauf hinzuweisen, daß das Pressenoberteil 11 an der linken Kante 13 einen Rücksprung 18 aufweist und das Pressenunterteil 12 nahe der linken Kante 14 mit einer Verdickung 15 versehen ist. Beide wirken sich gegenseitig unterstützend in der Weise zusammen, daß der Vorpreßling in seiner Lage festgehalten wird und das feste Verbinden von Schutzschicht und Vorpreßling gewährleistet ist.The left end of the hot press is shown more clearly in FIG. 5 than in FIG. 4. It should be particularly pointed out that the upper press part 11 has a recess 18 on the left edge 13 and the lower press part 12 is provided with a thickening 15 near the left edge 14. Both mutually support each other in such a way that the prepress is held in place and the firm connection of protective layer and preform is guaranteed.

Wenn das Verkleidungsprofil 1 fertiggepreßt ist, dann wird an der höher verdichteten unteren Kante 2 des Verkleidungsprofils - wie in Fig. 6 verdeutlicht - das strichpunktiert umrandete Teil 16 durch Profilfräsen entfernt.When the cladding profile 1 has been pressed, then the part 16, which is outlined in dash-dot lines, is removed by profile milling at the higher compressed lower edge 2 of the cladding profile.

Claims (6)

  1. An elongate lining profile pressed from a mixture of fibers mixed with a heat-hardenable binding agent and provided at its one longitudinal edge (2) with a slot and, at its other longitudinal edge (3) with a feather profile, especially suitable for the lining of the facades of buildings, characterized in that the lining profile has a wall thickness which increases chiefly continuously from the one to the other of its longitudinal edges, with the longitudinal edge (2) of greater wall thickness having a higher density than the longitudinal edge (3) of smaller wall thickness, and is provided with a firmly adhering protective layer coating on at least that particular surface which remains visible after its laying or installation.
  2. A device for producing the lining profile as claimed in claim 1,
    characterized by
    a) a rough-pressing tool consisting of the lower part of a pressing tool having a bottom (8) extending slantingly from the inside toward the outside, and of a frame member (6) capable of being lowered, surrounding said bottom (8) and forming a box therewith, as well as of an upper part (9) of a pressing tool whose surface as facing said lower part of the pressing tool is likewise designed to extend slantingly from the inside toward the outside and to have a thickened portion (10) on its outer edge, and by
    b) a hot-pressing tool consisting of a lower part (12) having a bottom extending from the outside toward the inside and designed to have a thickened portion (15) on its outer edge (14), as well as of an upper part (11) having a pressing surface extending slantingly in the same way as the bottom of said lower part (12) of the pressing tool.
  3. A device as claimed in claim 2, characterized in that it consists of a double rough-pressing tool and of a double hot-pressing tool which are composed of the mirror-inverted arrangement of two rough- and hot-pressing tools.
  4. A device as claimed in claims 2 and 3, characterized in that the upper part of said rough-pressing tool is provided with a thickened portion (10) on its edge facing said frame member (6).
  5. A device as claimed in claims 2 to 4, characterized in that the upper part (11) of said hot-pressing tool has at its outer edge (13) a somewhat set back portion (18) while the lower part (12) of said hot-pressing tool has a thickened portion (15) near its outer edge (14).
  6. A method for producing the lining profile as claimed in claim 1,
    characterized in that said mixture is first filled in such a way into the lower part of said rough-pressing tool as to form a plane surface, that thereafter the upper part of said pressing tool is lowered with said mixture thus being compressed to almost its final density, that the rough pressed block is then removed from said rough-pressing tool and, after having been turned by 180 angular degrees about its longitudinal axis, inserted in the lower part of said hot-pressing tool, with a protective layer being placed onto its surface, and pressed into its final shape in that the upper part of said hot-pressing tool is lowered and heat is applied.
