Description
Die Erfindung betrifft eine Rahmenanordnung aus massiven Profilwerkstücken aus Holz oder holzartigen Werkstoffen sowie ein Verfahren zur Verbindung von massiven Profilwerkstücken aus Holz oder holzartigen Werkstoffen zu einem Rahmen.The The invention relates to a frame assembly of solid profile workpieces Wood or wood-like materials and a method of connection of massive profile workpieces made of wood or wood-like materials into a frame.
Profilwerkstücke zur Bildung eines Rahmens beispielsweise von Fenstern, Türen, Rahmenverblendungen, Bildern, Wandvertäfelungen oder dgl. werden üblicherweise auf Gehrung geschnitten und an den durch die Schnittflächen gebildeten Stirnflächen zusammengefügt. Insbesondere bei der Montage von Rahmen mit bereits zusammengefügten Profilelementen sind die Verbindungsstellen mechanisch stark belastet.Profile workpieces for Formation of a frame, for example, windows, doors, frame panels, Pictures, wall paneling or the like become common Mitred cut and formed by the cut surfaces faces together. Especially when mounting frames with already assembled profile elements the joints are mechanically heavily loaded.
Zur Aufnahme der Kräfte sind mehrere Verbindungen möglich. Eine Leimverbindung kann bei fachgerechter Ausführung eine geeignete Tragfähigkeit aufweisen. Aufgrund langer Trocknungszeiten des Leimes ist eine derartige Verbindung unter Großserien-Fertigungsbedingungen unwirtschaftlich. Schraubverbindungen mit diagonal durch einen Gehrungsschnitt hindurchgeführten Schrauben erzeugen punktförmige Lasten im Bereich der Schraubköpfe bzw. der gegenhaltenden Muttern, was insbesondere bei weichen Materialien wie Holz zu einer unzureichenden Tragfähigkeit führen kann. Die für die Einführung der Schrauben erforderlichen Bohrungen entsprechen ferner nicht gehobenen optischen Anforderungen.to Absorption of forces several connections are possible. A glue joint can be a suitable load bearing capacity if expertly designed exhibit. Due to long drying times of the glue is a such connection under high volume production conditions uneconomical. Screw connections with diagonally through a miter cut guided through Screws create punctiform Loads in the area of the screw heads or the holding nuts, which is especially true for soft materials how wood can lead to inadequate carrying capacity. The for the introduction of the Bolts required holes also do not match upscale ones optical requirements.
Höher belastete Eckverbindungen können durch zusätzliche Verbindungselemente beispielsweise in Form zweischenkliger Winkel verstärkt werden. Solche von außen auf die Profilelemente angebrachten Winkelelemente kommen als Verbindungselemente nur für einfache Rahmenkonstruktionen ohne besonderen ästhetischen Wert in Betracht.Higher loaded Corner joints can through additional Connecting elements, for example in the form of zweischkliger angle reinforced become. Such from the outside attached to the profile elements angle elements come as connecting elements only for simple frame structures without special aesthetic value into consideration.
Des weiteren sind Rahmen aus Hohlprofilen bekannt, bei denen winklige Verbindungselemente innenseitig der Hohlprofile angeordnet sind. Eine derartige Verbindungstechnik erfordert einen Zusatzaufwand zur Festlegung der Verbindungselemente beispielsweise mit Schrauben oder durch Einschäumen mit einem aushärtbaren Kunststoffschaum.Of further frames are known from hollow sections, where angular Connecting elements are arranged inside the hollow sections. Such a connection technique requires additional effort for fixing the connecting elements, for example with screws or by lathering with a curable Plastic foam.

Der Erfindung liegt die Aufgabe zugrunde, eine Rahmenanordnung aus massiven Profilwerkstücken bereitzustellen, bei der die Verbindung einzelner Werkstücke untereinander unter Serienfertigungsbedingungen vereinfacht ist sowie ein Verfahren zur Fertigung einer Rahmenanordnung aus massiven Profilwerkstücken anzugeben.Of the Invention is based on the object, a frame assembly of solid Profile workpieces to provide, in which the connection of individual workpieces with each other simplified under mass production conditions as well as a procedure to specify for the production of a frame assembly of solid profile workpieces.
Die Aufgabe wird durch eine Rahmenanordnung mit den Merkmalen des Anspruchs 1 gelöst. Ein Verfahren zur Fertigung eines Rahmens ist im Anspruch 8 angegeben.The The object is achieved by a frame arrangement with the features of the claim 1 solved. A method for manufacturing a frame is specified in claim 8.
Die erfindungsgemäße Rahmenanordnung besteht aus massiven, zugeschnittenen Profilwerkstücken aus Holz oder holzartigen Werkstoffen, die mit ihren Schnittflächen aneinander anliegen. In mindestens einer der Schnittflächen ist eine Aushöhlung vorgesehen, so daß die zum Verbinden aneinanderliegenden Profilwerkstücke einen im wesentlichen geschlossenen Raum begrenzen. In den Raum mündet eine Einspritzbohrung, durch die ein klebender Zwei-Komponenten-Kunststoff in die Aushöhlung eingespritzt wird und zu einem Formteil aushärtet. Nach dem Aushärten bildet das Formteil das alleinige Verbindungselement zwischen den Werkstücken, wodurch die beiden Werkstücke mit einer hohen Endfestigkeit aneinander festgelegt sind. In der Rahmenebene ist eine stoffschlüssige sowie senkrecht zur Rahmenebene eine formschlüssige Verbindung gebildet, die hochbelastbar ist. Das Verbindungselement erlaubt eine einfache und hochbelastbare Verbindung auch bei kleinen Anlagequerschnitten. Der eigentliche Verbindungsvorgang beschränkt sich auf das Einspritzen des Zwei-Komponenten-Kunststoffs, wobei die beiden zu verbindenden Werkstücke vorzugsweise in einer Lehre gehalten sind. Der Verbindungsvorgang ist in einfacher Weise automatisierbar und läßt niedrige Taktzeiten zu. Die mit der Aushöhlung in Verbindung stehende Einspritzbohrung zum Einbringen des aushärtbaren Materials ist einfach zu fertigen und bedarf nach dem Aushärten der Masse gegebenenfalls nur einer geringfügigen kosmetischen Überarbeitung.The frame assembly according to the invention consists of solid, cut profile workpieces made of wood or wood-like materials which abut each other with their cut surfaces. In at least one of the cut surfaces, a cavity is provided, so that adjoin the adjoining profile workpieces define a substantially closed space. An injection hole opens into the room, through which an adhesive two-component plastic is injected into the cavity and cures to a molded part. After curing, the molded part forms the sole connecting element between the workpieces, whereby the two workpieces are fixed together with a high final strength. In the frame plane a cohesive and perpendicular to the frame plane a positive connection is formed, which is highly resilient. The connecting element allows a simple and highly resilient connection, even with small system cross sections. The actual connection process is limited to the injection of the two-component plastic, wherein the two workpieces to be joined are preferably held in a gauge. The connection process can be easily automated and allows low cycle times. The injection bore associated with the cavity for introducing the curable material is easy to manufacture and may require only minor cosmetic workover after curing of the composition.
In einer vorteilhaften Ausbildung weisen dabei beide aneinanderliegenden Schnittflächen je eine Aushöhlung auf, die symmetrisch zu einer durch die Schnittflächen gebildeten Teilungsebene ausgebildet sind. Dadurch ist sichergestellt, daß das nach dem Aushärten gebildete Verbindungselement an beiden Profilelementen zumindest näherungsweise die gleiche Haltekraft aufweist.In an advantageous embodiment, both have adjacent cut surfaces one excavation each on, which are symmetrical to one formed by the cut surfaces Dividing level are formed. This ensures that after curing formed connecting element on both profile elements at least approximately having the same holding force.
Abhängig von den auftretenden Belastungen können entsprechende Formen der Aushöhlungen gewählt werden, die be vorzugt in die Schnittfläche eingefräst werden. Der Fräsvorgang erlaubt eine schnelle und maßgenaue Einbringung der Aushöhlung in die entsprechende Stirnfläche und eignet sich sowohl für die Großserienfertigung wie auch für die Anfertigung einzelner Muster.Depending on the occurring loads can appropriate forms of excavations are chosen the be preferably milled into the cut surface. The milling process allows a fast and accurate Incorporation of the excavation in the corresponding end face and is suitable for both the mass production as well as for the production of individual patterns.
Ein guter Kompromiß zwischen hoher Tragfähigkeit und schneller Fertigung ist eine Ausbildung der Aushöhlung in Form eines Kreisscheibenausschnittes. Bei einer Ausbildung des Werkstückes mit einer flachen Querschnittsform hat sich eine Dicke der Aushöhlung als zweckmäßig herausgestellt, die etwa einem Drittel der Dicke des Profilwerkstückes entspricht. Das nach dem Aushärten entstehende Verbindungselement weist dabei eine hinreichende Querschnittsfläche auf und läßt gleichzeitig noch genügend Materialquerschnitt im Werkstück.One good compromise between high load capacity and faster manufacturing is a training of excavation in Shape of a circular disk cutout. In an embodiment of the workpiece with a flat cross-sectional shape has a thickness of the cavity as expediently which corresponds to about one third of the thickness of the profile workpiece. This after curing The resulting connecting element has a sufficient cross-sectional area and leaves at the same time still enough Material cross-section in the workpiece.
Auch eine formschlüssige Anbindung des Verbindungselementes in der Aushöhlung kann zweckmäßig sein. Bei einer Ausbildung mit entsprechenden Hinterschneidungen in einer Aushöhlung sind hohe Tragfähigkeiten erzielbar.Also a form-fitting Connection of the connecting element in the cavity may be appropriate. In a training with corresponding undercuts in one Excavation are high load capacities achievable.
Liegen die Profilwerkstücke mit ihren Schnittflächen sehr dicht aneinander an, kann für den Verbindungsvorgang die Anordnung einer Entlüftung für die Aushöhlung zweckmäßig sein. Dadurch kann mit geringem Druck bzw. entsprechend schnell die aushärtbare Masse eingespritzt werden. Bei einer geeigneten Ausbildung der Entlüftung beispielsweise in Form entsprechender Bohrungen führt die Entlüftung im Anschluß an das Ausfüllen der Aushöhlungen zu einem Austreten der eingespritzten Masse aus den Entlüftungsbohrungen. Nach dem Aushärten der eingespritzten Masse ist in diesem Bereich ein die Tragfähigkeit erhöhender Form schluß gegeben. Das Austreten der Masse aus der Entlüftung ist ferner ein zuverlässiger Indikator für eine vollständige Ausfüllung der Aushöhlung selbst.Lie the profile workpieces with their cut surfaces very close together, can for the connection process, the arrangement of a vent for the excavation be expedient. As a result, with little pressure or correspondingly fast, the hardenable mass be injected. For example, with a suitable design of the vent in the form of appropriate holes, the vent in the Connection to filling out the excavations to the leakage of the injected mass from the vent holes. After curing the injected mass is in this area a carrying capacity enhancing Form closed given. The leakage of the mass from the vent is also a reliable indicator for one full Completion of the erosion even.
Zur Fertigung eines Rahmens aus massiven Profilwerkstücken aus Holz oder holzartigen Werkstoffen werden die Profilwerkstücke zunächst auf Gehrung geschnitten, um dann in die Schnittfläche mindestens eines Profilwerkstückes eine Aushöhlung einzubringen. Anschließend wird eine in eine Aushöhlung mündende Einspritzbohrung gefertigt um dann die zu verbindenden Profilwerkstücke mit ihren Schnittflächen bündig aneinander zur Anlage zu bringen. Über die Einspritzbohrung wird in den durch die Aushöhlung gebildeten, im wesentlichen geschlossenen Raum ein klebender Zwei-Komponenten-Kunststoff eingespritzt, wobei die beim Einspritzen des Zwei-Komponenten-Kunststoffs verdrängte Luft zwischen den aneinanderliegenden Schnittflächen entweicht. Zum Schluß wird der eingespritzte Zwei-Komponenten-Kunststoff zur Bildung eines die Profilwerkstücke miteinander verbindenden Formteils ausgehärtet. Die beiden Komponenten können vorteilhaft gemeinsam eingespritzt und dabei miteinander vermischt werden, wobei die Komponenten hinsichtlich ihrer Viskosität und Reaktionszeit in einem weiten Bereich bedarfsgerecht eingestellt werden können. Die Aushärtung der Masse erfolgt zweckmäßig durch chemische Reaktion der beiden Komponenten miteinander. Die chemische Reaktion kann durch Zuführen von Wärme beschleunigt werden. Es können auch aufschäumbare Kunststoffe von insbesondere hoher Dichte geeignet sein, wodurch ein geringerer Einspritzdruck ausreichend ist. Durch den Aufschäumvorgang werden die Aushöhlungen auch bei einer komplexen Formgebung zuverlässig ausgefüllt.to Production of a frame made of solid profile workpieces Wood or wood-like materials, the profile workpieces are first mitred cut, then in the cut surface of at least one profile workpiece a erosion contribute. Subsequently one gets into a hollow opens Injection bore made around then the profile workpieces to be joined their cut surfaces flush to bring each other to the plant. About the injection hole is in through the excavation formed, essentially closed space an adhesive two-component plastic injected, taking the injection of the two-component plastic displaced air escapes between the adjacent cut surfaces. Finally, the Injected two-component plastic to form a profile workpieces with each other hardened connecting part. The two components can be beneficial injected together and mixed together, where the components in terms of their viscosity and reaction time in one wide range can be adjusted as needed. The curing the mass is carried out appropriately chemical reaction of the two components with each other. The chemical Reaction can be by feeding of heat be accelerated. It can also foamable Be particularly suitable for plastics of high density, which a lower injection pressure is sufficient. By the foaming process become the excavations reliably filled even with a complex shape.
