Abstract
Description
Die Erfindung bezieht sich auf ein Profil aus formgepreßten, mit Bindemitteln vermischten pflanzlichen Kleinteilen, insbesondere Holzkleinteilen, mit einem die Biegesteifigkeit erhöhenden Querschnitt, wobei an einander gegenüberliegenden Seiten des Profils längs durchlaufende rinnenförmige Vertiefungen oder/und leistenförmige Erhöhungen angeordnet sind.The invention relates to a profile made of compression-molded, small vegetable components mixed with binders, in particular small wooden parts, with a cross-section that increases the bending stiffness, with longitudinally running channel-shaped depressions and / or strip-shaped elevations being arranged on opposite sides of the profile.
Profile dieser Gattung sind aus der EP-A-0 086 899 oder DE-A 30 35 701 bekannt. Sie werden in endlicher Länge in einer Preßform gepreßt, in welcher vertikal- und horizontalbewegliche Preßstempel zwischen sich den Preßraum bilden. Diese Preßstempel werden paarweise nacheinander und zeitlich zueinander versetzt wiederholt voranbewegt, bis sie ihre das Profil umschließende Endstellung erreicht haben.Profiles of this type are known from EP-A-0 086 899 or DE-A 30 35 701. They are pressed to a finite length in a press mold in which vertically and horizontally movable press rams form the press space between them. These rams are moved in pairs one after the other and at different times until they have reached their final position enclosing the profile.
Beim genannten Stand der Technik wird im wesentlichen angestrebt, Palettenfuß-Riegel oder biegesteife Balken in Form eines I-,U-,Z-,L-Profils und dergleichen herzustellen.In the prior art mentioned, the main aim is to produce pallet foot bars or rigid beams in the form of an I, U, Z, L profile and the like.
Durch das DE-GM 19 43 588 ist eine formgepreßte Holzspanplatte bekannt, die an ihren schmalen Rändern nach Art von Nut und Feder ausgebildete, durchgehend verlaufende Vertiefungen und Erhöhungen aufweisen.From DE-GM 19 43 588 a molded wood chipboard is known which have formed on its narrow edges in the manner of tongue and groove, continuous depressions and elevations.
Auf der eingangs erwähnten Lehre aufbauend, setzt sich die Erfindung zur Aufgabe, die Querschnittsform solcher Profile weiterzuentwickeln, um biegesteife und großen Belastungen aussetzbare Profile anderen Querschnitts zu entwickeln, die nicht nur als Balken, sondern besonders auch als Bauelement, beispielsweise zur Bildung von Rahmen oder dergleichen, Verwendung finden können.Building on the teaching mentioned at the outset, the invention sets itself the task of further developing the cross-sectional shape of such profiles in order to develop rigid and large load-bearing profiles of other cross-section, which not only as a beam, but especially as a component, for example to form a frame or the like, can be used.
Die Erfindung besteht darin, daß eine als breite leistenförmige Stufe ausgebildete Erhöhung auf der einen Breitseite des Profils und mehrere rinnenförmige Vertiefungen auf der anderen Breitseite des Profils vorgesehen sind, wobei die zwischen den Vertiefungen befindlichen Stege jeweils eine geringere Breite als die leistenförmige Stufe besitzen.The invention consists in that a raised, broad strip-shaped step is provided on one broad side of the profile and several channel-shaped depressions on the other broad side of the profile, the webs located between the recesses each having a smaller width than the strip-shaped step.
Ein bevorzugtes Anwendungsbeispiel für solche Profile besteht in der Bildung von Rahmen, insbesondere Türrahmen bzw. Zargen, bei denen die erhabene Stufe als Anschlag für das Türblatt dient. Die demgemäß an der Rückseite des Profils befindlichen rinnenförmigen Vertiefungen haben einerseits die Funktion, die beim Formpressen in das Profil eingebrachten Spannungen zum Ausgleich zu bringen und zu vermeiden, daß aufgrund dieser Spannungen sich eine Deformation, beispielsweise Verwindung oder Biegung, des Profils einstellen kann. Aus diesem Grund lehrt die Erfindung im Rahmen eines bevorzugten Ausführungsbeispieles, daß die Breite der leistenförmigen Stufe etwa gleichgroß wie die Summe der Breiten der Stege ist.A preferred application example for such profiles is the formation of frames, in particular door frames or frames, in which the raised step serves as a stop for the door leaf. The trough-shaped depressions located on the back of the profile have the function on the one hand of compensating for the stresses introduced into the profile during compression molding and of avoiding deformation, for example twisting or bending, of the profile due to these stresses. For this reason, the invention teaches in a preferred embodiment that the width of the strip-shaped step is approximately the same size as the sum of the widths of the webs.
Andererseits kann mit Hilfe der rinnenförmigen Vertiefungen eine Verbundwirkung mit benachbarten Gegenständen herbeigeführt werden, indem man beispielsweise fließ- oder gießförmige Massen in diese rinnenförmigen Vertiefungen eingreifen läßt.On the other hand, with the help of the channel-shaped depressions, a composite effect with neighboring objects can be brought about, for example by allowing flow-like or pour-like masses to engage in these channel-shaped depressions.
Die Erfindung ist aber keinerwegs auf die Bildung von Profilen für Rahmen oder dergleichen beschränkt. Unter Zugrundelegung der erfindungsgemäßen Idee, sich in ihrer Wirkung kompensierende Formgebungen auf gegenüberliegenden Seiten des Profils zu bilden, lassen sich eine Vielzahl beliebig gestalteter Profile für die verschiedensten Anwendungszwecke entwickeln, z.B. Geländerstäbe und -läufe, Deckel, Kästen und dergleichen.However, the invention is in no way limited to the formation of profiles for frames or the like. On the basis of the idea according to the invention of forming shapes which compensate for their effect on opposite sides of the profile, a large number of profiles of any design can be used for the most varied of them Develop applications, such as railing bars and rails, lids, boxes and the like.
Weitere Einzelheiten der Erfindung ergeben sich aus den Unteransprüchen. Danach ist beispielsweise vorgesehen, daß die zwischen bzw. neben den rinnenförmigen Vertiefungen befindlichen Stege sowie die leistenförmige Stufe in ihren peripheren Schichten eine größere Verdichtung als die mittleren Profilbereiche aufweisen. Wie man derartige Verdichtungen erreichen kann, läßt sich der eingangs erwähnten EP-A-0 086 899 entnehmen.Further details of the invention emerge from the subclaims. According to this, it is provided, for example, that the webs located between or next to the channel-shaped depressions and the strip-shaped step have a greater compression in their peripheral layers than the central profile regions. How one can achieve such densifications can be found in the aforementioned EP-A-0 086 899.
Die einzelnen rinnenartigen Vertiefungen sollten einen von außen nach innen sich verjüngenden, insbesondere trapez- oder hohlkehlenförmigen Querschnitt aufweisen. Diese Maßnahme ist nicht nur zum leichten Entformen der Preßwerkzeuge zweckmäßig; sie dient auch der Bildung kerbunempfindlicher Bereiche des Profils.The individual groove-like depressions should have a cross-section which tapers from the outside inwards, in particular trapezoidal or fillet-shaped. This measure is useful not only for easy demoulding of the pressing tools; it also serves to form notch-sensitive areas of the profile.
Schließlich sieht die Erfindung vor, daß das Profil eingepreßte Kammern, bzw. zurückversetzte Flächen zur Aufnahme von Beschlägen, Schlössern oder dergleichen aufweist. Auch diese Kammern, bzw. zurückversetzten Flächen werden im gleichen Arbeitsgang wie die Bildung des Profiles mit Hilfe von entsprechend gestalteten Vorsprüngen an den Preßwerkzeugen gebildet. Diese Maßnahme hat den Vorteil, daß die Wandungen solcher Kammern bzw. die zurückversetzten Flächen eine hochfeste Oberfläche besitzen und daher besonders geeignet zur Aufnahme von Schrauben oder dergleichen Verbindungsmitteln sind. Diese Kammern bzw. zurückversetzten Flächen können beliebige Formen besitzen.Finally, the invention provides that the profile has pressed-in chambers, or recessed surfaces for receiving fittings, locks or the like. These chambers or recessed surfaces are also formed in the same operation as the formation of the profile with the aid of appropriately designed projections on the pressing tools. This measure has the advantage that the walls of such chambers or the set-back surfaces have a high-strength surface and are therefore particularly suitable for receiving screws or similar connecting means. These chambers or recessed surfaces can have any shape.

Im Ausführungsbeispiel der Figur 1 ist der Querschnitt eines erfindungsgemäßen Profiles (1) gezeigt, das an einer Seite eine erhabene, in Profillängsrichtung durchlaufend angeordnete, leistenförmige Stufe (2) aufweist. An der gegenüberliegenden Seite besitzt das Profil (1) beim Ausführungsbeispiel mehrere parallel zueinander angeordnete und ebenfalls in Profillängsrichtung sich durchlaufend erstreckende rinnenförmige Vertiefungen (3). Die Flanken der Vertiefungen (3) sind so ausgebildet, daß sie einen sich von außen nach innen verjüngenden Querschnitt der Vertiefung (3) bilden. Im Beispiel der Figur 1 sind trapezförmige Querschnitte der Vertiefungen (3) gezeigt, deren Flächen abgerundet ineinander übergehen. Man kann aber auch gewölbte, d.h. hohlkehlenförmige Querschnitte der Vertiefungen (3) bilden.In the exemplary embodiment in FIG. 1, the cross section of a profile (1) according to the invention is shown, which has on one side a raised, strip-shaped step (2) arranged continuously in the longitudinal direction of the profile. On the opposite side, the profile (1) in the exemplary embodiment has a plurality of channel-shaped depressions (3) which are arranged parallel to one another and also extend continuously in the longitudinal direction of the profile. The flanks of the recesses (3) are designed such that they form a cross section of the recess (3) that tapers from the outside inwards. In the example in FIG. 1, trapezoidal cross sections of the depressions (3) are shown, the surfaces of which merge into one another in a rounded manner. But you can also vaulted, i.e. form a fillet-shaped cross-section of the depressions (3).
Solche Profile (1) werden in Formen mit Hilfe von einander entgegenwirkenden Preßstempeln erzeugt, die zwischen sich einen Hohlraum zum Einfüllen eines Gemisches aus Bindemitteln und pflanzlichen Kleinteilen, insbesondere Holzkleinteilen, bilden. Indem diese Preßstempel paarweise und je Paar zueinander versetzt stufenweise voranbewegt werden, verdichten sie das eingefüllte Gemisch, bis die Preßstempel in der Preßendstellung das fertige Profil (1) umhüllen.Such profiles (1) are produced in molds with the aid of opposing press rams which form a cavity between them for filling in a mixture of binders and small plant parts, in particular small wooden parts. By progressively moving these stamps in pairs and in pairs offset from one another, they compact the filled mixture until the stamps envelop the finished profile (1) in the final press position.
Durch das wiederholte und abschnittsweise Pressen des Kleinteil-Gemisches bilden sich an den peripheren Schichten (5) der Stufe (2) bzw. der zwischen den rinnenförmigen Vertiefungen (3) befindlichen Stege (4) Zonen größerer Verdichtung, welche die Oberfläche des Profils glatt und unverletzlich machen.Due to the repeated and section-wise pressing of the mixture of small parts, zones of greater compaction are formed on the peripheral layers (5) of the step (2) or the webs (4) located between the groove-shaped depressions (3), which smooth and smooth the surface of the profile make invulnerable.
Im Beispiel der Figur 1 ist ferner mit den strichpunktierten Linien (6) angedeutet, wie man das im Querschnitt gezeigte Profil (1) zu einem Rahmen, insbesondere Türrahmen bzw. Zarge, zusammenfügen kann. Die Fügetechnik ist die gleiche wie beim Rahmenbau unter Verwendung von Naturholz. Die Stufe (2) wirkt dann als Türanschlag, der wegen seiner preßtechnisch erzeugten Formgebung besonders stabil und beschädigungsunempfindlich ist.In the example in FIG. 1, the dash-dotted lines (6) also indicate how the profile (1) shown in cross section can be joined to form a frame, in particular a door frame or frame. The joining technique is the same as for frame construction using natural wood. Step (2) then acts as a door stop, which is particularly stable and insensitive to damage due to its shaping created by the press.
Würde man das Profil gemäß Figur 1 lediglich einseitig mit der Stufe (2) ausbilden und die gegenüberliegende Seite glatt gestalten, dann ergäben sich aus dem Preßvorgang Spannungen im Gefüge, die zur Formänderung des Profiles, insbesondere zur Verwindung und Biegung, führen würden. Wenn aber die rinnenförmigen Vertiefungen (3) mit den dazwischen befindlichen Stegen (4) gleichzeitig mit der Stufe (2) gebildet werden, entsteht eine Kompensation der eingebrachten Spannungen mit der Folge, daß derartig hergestellte Profile auch unter extremen Witterungsbedingungen und -änderungen ihre ursprüngliche Form behalten.If the profile according to FIG. 1 were to be formed only on one side with step (2) and the opposite side was made smooth, then the pressing process would result in tensions in the structure, which would lead to a change in shape of the profile, in particular to twisting and bending. However, if the trough-shaped depressions (3) with the webs (4) between them are formed at the same time as the step (2), a compensation of the stresses is created, with the result that profiles produced in this way retain their original shape even under extreme weather conditions and changes to keep.
Man kann diese rinnenförmigen Vertiefungen (3), deren Anzahl nach Verwendungsart des Profiles (1) beliebig verändert werden kann, auch konstruktiv nutzen, indem man die Profile (1) mit einer flüssigen oder pasteusen Masse umhüllt und damit einen scherfesten Verbund mit der Umgebung bewirkt.You can also use these trough-shaped depressions (3), the number of which can be changed as desired depending on the type of use of the profile (1), by enveloping the profiles (1) with a liquid or paste-like mass and thus creating a shear-resistant bond with the environment .
Es liegt auf der Hand, daß erfindungsgemäße Profile (1) je nach dem Verwendungszweck eine unterschiedliche Querschnittsgestaltung abweichend vom Beispiel der Figur 1, erhalten können, wobei immer darauf geachtet werden sollte, daß den auf der einen Profilseite befindlichen Erhöhungen mindestens eine, vorzugsweise mehrere Vertiefungen auf der anderen Seite gegenüberliegen sollten.It is obvious that profiles (1) according to the invention can have a different cross-sectional configuration, different from the example in FIG. 1, depending on the intended use, it should always be ensured that the elevations on one side of the profile have at least one, preferably several, depressions on the other side.
In Fig. 2 ist der Querschnitt einer solchen bevorzugten Variante dargestellt. Danach sind die erhabenen Profilteile (2) und (4) besonders dimensioniert. Es hat sich nämlich in der Praxis als sehr vorteilhaft erwiesen, wenn die Breite (a) der leistenförmigen Stufe (2) gleichgroß wie die Summe der Breiten (b) der Stege (4) ist. Dementsprechend ergibt sich die Dimensionierung der rinnenförmigen Vertiefungen (3), deren Abstände voreinander nicht gleich groß sein müssen, sondern entsprechend den Belastungen auch variiert werden können.2 shows the cross section of such a preferred variant. Then the raised profile parts (2) and (4) are specially dimensioned. It has proven to be very advantageous in practice if the width (a) of the strip-shaped step (2) is the same size as the sum of the widths (b) of the webs (4). Accordingly, the dimensions of the trough-shaped depressions (3) result, the distances between which need not be the same size, but can also be varied in accordance with the loads.
Der Teilquerschnitt der Figur 3 zeigt in Verbindung mit der Draufsicht in Figur 4 die Möglichkeit, Kammern (7) oder/und zurückversetzte Flächen (8) im Profil (1) vorzusehen, die im gleichen Arbeitsgang wie die Stufe (2) und die rinnenförmigen Vertiefungen (3) hergestellt werden. Diese Kammern (7) dienen zur Aufnahme von Beschlägen, beispielsweise von Schlössern. Die zurückversetzte Fläche (8) ist bei diesem Ausführungsbeispiel dafür vorgesehen, einen Flansch des Beschlages so aufzunehmen, daß die Außenfläche des Flansches bündig mit der Seitenfläche (9) des Profils (1) zu liegen kommt.
Zur Herstellung des erfindungsgemäßen Profils wird wie folgt vorgegangen:The partial cross section of FIG. 3, in conjunction with the top view in FIG. 4, shows the possibility of providing chambers (7) and / or recessed surfaces (8) in profile (1) that work in the same operation as step (2) and the channel-shaped depressions (3) can be produced. These chambers (7) are used to hold fittings, for example locks. The set back surface (8) is provided in this embodiment for receiving a flange of the fitting so that the outer surface of the flange comes to lie flush with the side surface (9) of the profile (1).
The procedure for producing the profile according to the invention is as follows:
Das Profil (1) wird in einer gegenüber Figur 1 um 90 Grad verdrehten Lage hergestellt, wobei beispielsweise die Seitenfläche (9) und die Stufe (2) des Profils (1) unten liegen. In der fertigen Preßendstellung des Profils (1) wird dieses von zwei Preßstempelpaaren umhüllt. Die beiden querbeweglichen Preßstempel bilden die Seitenflächen (10) des Profils (1). Der untere der vertikalbeweglichen Preßstempel bildet die Seitenflächen (9 und 12) und der obere dieses Preßstempelpaares bildet die Seitenfläche (11) des Profiles (1). Diese Stellung hat sich deswegen bewährt, weil dann der Einfüllvorgang in den Raum zwischen den Preßstempeln im freien Fall erleichtert wird. Die Stirnflächen der vertikalbeweglichen Preßstempel weisen bei einer Ausführungsform das Ebenbild der ihnen zugekehrten Seitenflächen (9,12 bzw. 11) auf. Der obere Preßstempel ist zum Zwecke des Befüllens des Preßraumes entfernt worden. Nachdem der Preßraum befüllt worden ist, werden zunächst die vertikalbeweglichen Preßstempel gegeneinander bewegt, während die seitlichen, die Seitenflächen (10) bildenden Preßstempel in ihrer Lage verbleiben. Dadurch wird eine Vorpressung des Kleinteil-Gemisches bewirkt. Nach dem ersten vertikalen Vorpreßgang empfiehlt es sich, den ersten horzizontalen Vorpreßgang durchzuführen und dann, je nach Größe des Profiles, weitere Teilpreßgänge anzuschließen, bis die Preßstempel eine das Profil umhüllende Stellung erreicht haben.The profile (1) is produced in a position rotated by 90 degrees with respect to FIG. 1, the side surface (9) and the step (2) of the profile (1) being at the bottom, for example. In the finished press end position of the profile (1), it is encased by two pairs of press rams. The two transverse press rams form the side surfaces (10) of the profile (1). The lower of the vertically movable ram forms the side surfaces (9 and 12) and the upper of this pair of ram forms the side surface (11) of the profile (1). This position has proven itself because the filling process in the space between the ram is then facilitated in free fall. In one embodiment, the end faces of the vertically movable press rams have the same image as the side faces (9, 12 or 11) facing them. The upper press ram has been removed for the purpose of filling the press space. After the press chamber has been filled, the vertically movable press rams are first moved against one another, while the lateral press rams forming the side surfaces (10) remain in their position. This causes the mixture of small parts to be pre-pressed. After the first vertical pre-press cycle, it is advisable to carry out the first horizontal pre-press cycle and then, depending on the size of the profile, to connect further sub-press cycles until the press rams have reached a position enveloping the profile.
Sofern in das Profil (1) Kammern (7), zurückversetzte Flächen (8) oder dgl. beim Formpressen eingebracht werden sollen, empfiehlt es sich, die Preßstempel an den zugeordneten Stellen mit entsprechenden Preßstempelansätzen zu versehen, damit die Formgebung des Profiles und der Kammern (7) bzw. vertieften Flächen (8) in einem Arbeitsgang erfolgen kann.If chambers (7), set-back surfaces (8) or the like are to be introduced into the profile (1) during compression molding, it is advisable to provide the press rams with corresponding press ram attachments at the assigned points, so that the shape of the profile and the chambers (7) or recessed surfaces (8) can be done in one operation.
