Abstract

In the process described, the panel (1) consists of layers (3, 4) of which at least one (3) has been cross-sectionally weakened and bevelled and, after flexural distorsion, is joined to the other layer (4) by bonding and compression techniques. The cross-sectional weakening of at least one layer (3, 4) is produced by forming, by chip-removal, of grooves (5) parallel to one another; the intermediate parts (6) are, at the point where the panel (1) has to have weakened walls (2), bevelled by chip removal at a specified angle.

Description

Die Erfindung bezieht sich auf Verfahren zur Herstellung einer Hohlbauplatte aus Holz oder Holzersatzstoffen, bei dem zwei ursprünglich vollwandige Teilplatten an jeweils einer Seite ausgekehlt werden, so daß zwischen stehenbleibenden Stegen rinnenförmige Vertiefungen entstehen, wonach die Teilplatten an den Stirnflächen der Stege verleimt und mit den gegeneinander gerichteten Stegen zusammengepreßt werden.The invention relates to methods for producing a hollow building board made of wood or wood substitutes, in which two originally full-walled part panels are fluted on one side, so that between standing webs trough-shaped depressions arise, after which the part panels glued to the end faces of the webs and with each other directed webs are pressed together.

Derartige Hohlbauplatten sind in der DE-C-30 44 039 beschrieben und werden im wesentlichen zur Herstellung von Türen benötigt.Such hollow building boards are described in DE-C-30 44 039 and are essentially required for the production of doors.

Der Erfindung liegt die Aufgabe zugrunde, unterschiedlich dicke Platten zu entwickeln, die einerseits in verfahrensmäßig günstiger Weise hergestellt werden können und andererseits eine hohe Stabilität aufweisen.The invention is based on the object of developing panels of different thicknesses which on the one hand can be produced in a process-favorably manner and on the other hand have high stability.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß mindestens eine Teilplatte längs mindestens eines Randes bis zum Rand abgeschrägt wird, so daß Stege unterschiedlicher Höhe entstehen, wonach der durch die Abschrägung geschwächte Teilplatten-Bereich gegen die Stege der gegenüberliegenden Teilplatte biegeverformt wird und die Teilplatten anschließend zur Bildung einer Hohlbauplatte mit unterschiedlicher Dicke verleimt und gegeneinander gepreßt werden.This object is achieved in that at least one partial plate is chamfered along at least one edge to the edge, so that webs of different heights are formed, after which the partial plate area weakened by the bevel is bent deformed against the webs of the opposing partial plate and the partial plates subsequently to Formation of a hollow building board with different thicknesses glued and pressed against each other.

Im Rahmen der Erfindung sind zahlreiche Varianten ableitbar, die sich aus den Unteransprüchen ergeben.Within the scope of the invention, numerous variants can be derived which result from the subclaims.

So ist es beispielsweise möglich, die Reduzierung der Plattendicke über den gesamten Plattenumfang, oder nur einen Teil hiervon durchzuführen. Wenn zwei aneinandergrenzende Plattenseiten mit solchen Abschrägungen versehen sein sollen, empfiehlt es sich im Sinne der Erfindung, die Stege im Bereich des Plattenüberganges von normaler auf reduzierte Plattendicke quer zu ihrer Längsachse einzukerben, oder in sonstiger Weise zu durchbrechen. Auf diese Weise wird ermöglicht, die mit abgeschrägten Stegen versehene Schicht (Teilplatte) so zu verformen, daß im Eckenbereich der Platte sich eine Art Grat zwischen den unterschiedlich geneigten Abschrägungen der Platte ergibt.For example, it is possible to reduce the plate thickness over the entire plate circumference, or only a part thereof. If two adjoining plate sides are to be provided with such bevels, it is advisable in the sense of the invention to notch the webs in the region of the plate transition from normal to reduced plate thickness transversely to their longitudinal axis, or to break through in some other way. In this way it is possible to deform the layer (partial plate) provided with bevelled webs in such a way that in the corner region of the plate there is a kind of ridge between the differently inclined bevels of the plate.

In einer anderen zweckmäßigen Ausgestaltung der Erfindung ist vorgesehen, daß mindestens ein in der Hohlbauplatte gegenüberliegendes Rinnenpaar bis zum Rand der Teilplatten ausgefräst und in dieses Rinnenpaar ein im Querschnitt angepaßtes Profil eingesetzt und mit den Teilplatten verklebt bzw. verpreßt wird.In another expedient embodiment of the invention, it is provided that at least one pair of channels lying opposite in the hollow building board is milled out to the edge of the partial plates and a profile with an adapted cross section is inserted into this pair of channels and glued or pressed to the partial plates.

Solche Profile sind gemäß den Unteransprüchen für unterschiedliche Zwecke einsetzbar, beispielsweise zum Zwecke des Armierens der Platte oder der Bildung eines Beschlages für eine Steckverbindung benachbarter Platten, oder um eine Basis für das Einbringen von Gewindebohrungen und dergleichen Verbindungsmitteln zu schaffen.Such profiles can be used according to the subclaims for different purposes, for example for the purpose of reinforcing the plate or the formation of a fitting for a plug connection of adjacent plates, or to create a basis for the introduction of threaded holes and the like connecting means.

Solche einsetzbare Profile können aus den unterschiedlichsten Materialien gebildet werden,beispielsweise aus Metall, wobei sich Leichtmetall-Profile in besonderer Weise empfehlen. Wenn es aber darum geht, Verbindungselemente, wie z.B. Schrauben, fest zu verankern, dann empfiehlt es sich, in die Rinnen Profile aus schichtweise aufgebautem Hartholz einzusetzen, wobei solche Profile nicht unbedingt die Rinne zu durchsetzen, sondern nur im Bereiche der Verbindungsstellen kurze Längen aufzuweisen brauchen.Such usable profiles can be formed from a wide variety of materials, for example metal, with light metal profiles being particularly recommended. But when it comes to firmly anchoring connecting elements, such as screws, it is advisable to place them in the channels To use profiles made of hardwood built up in layers, whereby such profiles do not necessarily have to penetrate the gutter, but only need to have short lengths in the area of the connection points.

Im Beispiel der Fig. (1) ist ein teilweiser Querschnitt durch eine Platte (1) gezeigt, die an mindestens einer Seite eine Abschrägung (2) aufweisen soll. Die Erfindung geht davon aus, daß diese Platte (1) aus mindestens zwei Schichten (Teilplatten) (3,4) gebilded wird, von denen die Schicht (3), welche die Abschrägung (2) enthält, querschnittsgeschwächt ist und entlang der Grundebene (8) mit der anderen Schicht (45) verbunden wird. Es ist natürlich denkbar, auch die andere Schicht (4) mit einer solchen Abschrägung (2) zu versehen oder die Platte (1) aus mehreren Schichten zu bilden. Wesentlich ist dabei, daß diejenige Schnicht, welche die Abschrägung (2) enthält, querschnittsgeschwächt ausgebildet und deshalb verformbar gestalter ist.In the example in FIG. (1), a partial cross section through a plate (1) is shown, which should have a bevel (2) on at least one side. The invention is based on the assumption that this plate (1) is formed from at least two layers (partial plates) (3, 4), of which the layer (3), which contains the bevel (2), is cross-sectionally weakened and along the base plane ( 8) is connected to the other layer (45). It is of course conceivable to provide the other layer (4) with such a bevel (2) or to form the plate (1) from several layers. It is essential here that the face which contains the bevel (2) is designed with a weakened cross-section and is therefore designed to be deformable.

Im Beispiel der Fig. (2) ist gezeigt, daß die einzelne Schicht (3,4) beispielsweise aus einer massiven Holzplatte, insbesondere Holzspanplatte besteht, in welche Rinnen (5) spanabhebend eingeformt werden. Bevorzugt sind die Rinnen 55) parallel zueinander angeordnet. Mindestens eine der Teilplatten (3,4), im Beispiel der Fig. (2) ist es die Teilplatte (3), wird entlang enier Fräsebene (9) spanabhebend bearbeitet. Diese Bearbeitung hat zur Folge, daß die Stege (6) längs dieser Fräsebene (9) spanabhebend verkürzt werden.In the example in FIG. (2) it is shown that the individual layer (3, 4) consists, for example, of a solid wooden plate, in particular chipboard, into which grooves (5) are formed by machining. The grooves 55) are preferably arranged parallel to one another. At least one of the partial plates (3, 4), in the example in FIG. (2) it is the partial plate (3), is machined along a milling plane (9). This processing has the consequence that the webs (6) along this milling plane (9) are shortened by machining.

Wenn man nun die einander zugekehrten Flächen der Teilplatten (3,4) mit Klebstoff (7) versieht und miteinander verpreßt, ergibt sich eine Formgebung der Teilplatten (3,4), beispielsweise entsprechend der Form nach Fig. (1). Entscheidend ist hierbei, daß die Fräsebene (9) gemäß Fig. (2) in die Grundebene (8) gemäß Fig. (1) und (2) durch Verformung eines oder mehrerer der Teilplatten (3,4) gebracht wird. Es ist leicht einzusehen, daß auch die Teilplatte (4) verformt werden müßte, wenn sie eine Verkürzung ihrer Stege (6) längs einer Ebene analog zur Fräsebene (9) aufweisen würde.If the surfaces of the partial plates (3, 4) facing one another are now provided with adhesive (7) and pressed together, the partial plates (3, 4) are shaped, for example in accordance with the shape according to FIG. (1). It is crucial here that the milling plane (9) according to FIG. (2) is brought into the basic plane (8) according to FIGS. (1) and (2) by deforming one or more of the partial plates (3, 4). It is easy to see that the partial plate (4) would also have to be deformed if it had a shortening of its webs (6) along a plane analogous to the milling plane (9).

In den Beispielen der Figuren (3) und (4) ist gezeigt, daß die spanabhebene geformten Rinnen (5) über Auskehlungen (11) in die Grundebene (8) gemäß Fig. (1) und (2) auslaufen und damit einen massiven Rahmenbereich (10) bilden, welcher an der Platte (1) umlaufend angeordnet ist. Die Teilplaten (3,4) werden in diesen Rahmenbereichen (10) miteinander verklebt und daher massiv gestaltet.In the examples of Figures (3) and (4) it is shown that the machined grooves (5) run out via fillets (11) into the base plane (8) according to FIGS. (1) and (2) and thus a solid frame area Form (10), which is arranged on the plate (1) all around. The partial panels (3, 4) are glued to one another in these frame areas (10) and are therefore designed to be solid.

Man kann aber auch die Rinnen (5) bis zum Rand der einzelnen Teilplatte (3,4) durchlaufend gestalten, wie dies in Fig. (4) dargestellt ist. Dann ergibt sich eine nur teilweise Verbindung der Rahmenbereiche (10), was aber zur Folge hat, daß Beschläge eingesetzt werden können (vgl. Fig. (11)), die geeignet sind, benachbarte Platten (1) miteinander zu verbinden.But you can also design the channels (5) to the edge of the individual sub-plate (3,4) continuously, as shown in Fig. (4). Then there is only a partial connection of the frame areas (10), but this has the consequence that fittings can be used (see FIG. (11)) which are suitable for connecting adjacent panels (1) to one another.

Im Ausführungsbeispiel der Figuren (5) und (6) wird zunächst davon ausgegangen, daß eine Teilplatte (4) entlang der Fräsebene (9) spanabhebend bearbeitet wird, während die andere Teilplatte (3) unbearbeitet bleibt. Beide Teilplatten (3,4) sind vorher natürlich zur Bildung der Rinnen (5) spanabhebend ausgekehlt worden.In the embodiment of Figures (5) and (6) it is initially assumed that one part plate (4) is machined along the milling plane (9), while the other part plate (3) remains unprocessed. Both partial plates (3, 4) have of course been previously machined to form the channels (5).

Um die Stege (6) dieser Teilplatten (3,4) miteinander zu verbinden, ist es erforderlich, die Teilplatte (4) durch Biegung zu verformen. Es versteht sich, daß die Fräsebene (9) so gelegt werden muß, daß die Stirnflächen der Stege (6) plan aneinander zur Anlage kommen können. Das Ausführungsbeispiel der Figuren (5) und (6) zeigt, daß die Platte (1) in einer Oberfläche plan und an der anderen Oberfläche stellenweise abgeschrägt ist. Die Verformung befindet sich an der Stelle, wo die Abschrägung (2) beginnt. In der Regel sollte sich an dieser Stelle eine Auskehlung bzw. Rinne (5) befinden, so daß von der Verformung nur die Restwandstärke betroffen ist.In order to connect the webs (6) of these partial plates (3, 4) to one another, it is necessary to deform the partial plate (4) by bending. It is understood that the milling plane (9) must be placed so that the end faces of the webs (6) can come to rest flat against each other. The embodiment of Figures (5) and (6) shows that the plate (1) is flat in one surface and beveled in places on the other surface. The deformation is at the point where the bevel (2) begins. As a rule, a groove or groove (5) should be located at this point, so that only the residual wall thickness is affected by the deformation.

Beim Ausführungsbeispiel der Figuren (7) und (8) wird gezeigt, wie eine Platte (1) an beiden Oberflächen abgeschrägt werden kann. Dies wird dadurch erreicht, daß die Stege (6) beider beider Teilplatten (3,4) längs der beiden Fräsebenen (9) verhürzt werden. Je nachdem, welcher Winkel der einzelnen Fräsebene (9) zugeordnet wird, lassen sich unterschiedliche Neigungen der Abscbrägungen (2) erzielen.In the embodiment of Figures (7) and (8) it is shown how a plate (1) can be chamfered on both surfaces. This is achieved in that the webs (6) of both of the two partial plates (3, 4) are shortened along the two milling planes (9). Depending on the angle assigned to the individual milling plane (9), different inclinations of the bevels (2) can be achieved.

Entsprechend dem Ausführungsbeispiel nacht den Figuren (9) und (10) können Abschrägungen auch um die Ecke einer Platte (1) herumgeführt werden. Es ist hierbei lediglich erforderlich, die Stege (6) mit Kerben (13) oder sonstigen Auskehlungen längs der Biegelinie zu versehen, sofern die zugeordnete Teilplatte (4) Längs dieser Kerben (13) biegeverformt werden muß.According to the embodiment shown in Figures (9) and (10), bevels can also be made around the corner of a plate (1). It is only necessary to provide the webs (6) with notches (13) or other grooves along the bending line, provided that the associated partial plate (4) has to be bent along these notches (13).

Wenn zwei aneinandergrenzende Seiten einer Platte in diesem Sinne verformt werden, ergibt sich eine symbolische Kante (14), wie sie in Fig. (10) gezeigt ist. In Figur (10) ist auch strichpunktiert angedeutet, wie die Rinnen (5) in diesem Fall ausgebildet sind. Es versteht sich von selbst, daß die Pressung der Teilplatten (3,4) so lang aufrechterhalten bleibt, bis der Klebstoff zwischen den Stegen (6) abgebungen hat.If two adjoining sides of a plate are deformed in this way, a symbolic edge (14) results, as shown in FIG. (10). In FIG. (10) it is also indicated by dash-dotted lines how the channels (5) are designed in this case. It goes without saying that the pressing of the partial plates (3, 4) is maintained until the adhesive between the webs (6) has come off.

Im Beispiel der Fig. (11) sind Maßnahmen gezeigt, wie sie zur Anwendung bei der erfindungsgemäßen Platte geeignet erscheinen. Diese Maßnahmen sind jeweils einzeln zu betrachten, obwohl sie in einer Figur gezeigt sind.In the example of FIG. (11), measures are shown as they appear to be suitable for use in the plate according to the invention. These measures are to be considered individually, although they are shown in a figure.

Man kann z.B. die Rinne (5) einer Teilplatte (3,4) zylinderförmig gestalten und damit ein rohrförmiges Rohrprofil (15) einsetzen, welches sowohl als Versteifung, als auch als Beschlag dienen kann. Anstelle eines Rohrprofils (15) kann ein zylindrisches massives Profil eingesetzt werden.You can e.g. design the channel (5) of a partial plate (3, 4) in a cylindrical shape and thus use a tubular tubular profile (15) which can serve both as a stiffener and as a fitting. Instead of a tubular profile (15), a cylindrical solid profile can be used.

Die Profilierung kann aber auch in Form eines Rechteckes (16) oder eines Quadrats (17) gebildet werden. Im Falle der Fig. (11) ist auch die Verwendbarkeit eines besonders geformten Profiles, beispielweise eines I-Profiles (18) gezeigt.The profile can also be formed in the form of a rectangle (16) or a square (17). In the case of FIG. (11), the usability of a specially shaped profile, for example an I profile (18), is also shown.

diese vorgenannten Profile dienen im wesentlichen zur Versteifung der Platte (1) in Sinne einer Armierung.these aforementioned profiles essentially serve to stiffen the plate (1) in the sense of a reinforcement.

Es ist aber auch möglich, Profile in Form schichtweise aufgebauter Harthölzer (19) einzusetzen, die beispielsweise als Delignite (WZ) bezeichnet werden. Solche Harthölzer eignen sich speziell dafür, Grundbasis für Schraubbohrungen und dergleichen Verbindungsmittel zu bilden. Aus diesem Grunde können solche Verbindungsmittel auch verhältnismäßig kurz bemessen und an solchen Stellen angeordnet werden , wo Verbindungsmaßnahmen getroffen werden müssen.However, it is also possible to use profiles in the form of hardwoods (19) built up in layers, which are referred to, for example, as delignites (WZ). Such hardwoods are particularly suitable for forming the base for screw holes and the like connecting means. For this reason, such connecting means can also be dimensioned relatively short and arranged in such places where connecting measures have to be taken.
