Description
Tischlerplatte. Die bekannten Tischlerplatten bestehen oft aus einer Blindholzlage, die ein- oder beidseitig mit Furnierblättern versehen ist. Wichtig ist hierbei die Beschaffenheit der Blindholzlage, da diese für die Festigkeit der Platte bestimmend ist.
Während die Blindholzlage bekannter Tischlerplatten aus miteinander verleimten Holzstäbchen besteht, wobei das Planbleiben der Platte von der Breite der zusammengeleimten Stäbchen ab hängt, besteht bei der Tischlerplatte nach der vorliegenden Erfindung die Blindholzlage aus einem zusammenhängenden Holzbrett, das mindestens einseitig mit in Faserrichtung des Holzes verlaufenden Schlitzen versehen ist. Dadurch kommt das lästige und zeit raubende Verleimen von Holzstäbchen in Wegfall,
während man trotzdem eine span nungsfreie und gut abgesperrte Tischler platte erhalten kann.
Auf der beiliegenden Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegen standes veranschaulicht. Fig. 1 zeigt im Schaubild eine Blindholz lage.
Fig. 2 zeigt einen Längsschnitt durch eine fertige Tischlerplatte, und Fig. 8 zeigt eine Stirnansicht einer sol chen Platte. Die in F'ig. 1 dargestellte Blindholzlage 1 besteht aus einem ununterbrochen durch gehenden Holzbrett, wie solches aus Baum stämmen gesägt wird. In diesem Brett sind mehrere parallel zueinander, in Richtung der Fasern verlaufende Schlitzreihen angeordnet.
Eine solche Schlitzreihe weist eine Anzahl hintereinander liegende Schlitze 2 auf, die durch die ganze Brettstärke durchgehen, und die zu den Schlitzen der benachbarten Schlitz reihen versetzt sind. Diese in verhältnis mässig geringen Abständen (ca. 8 mm) von einander angeordneten Schlitzreihen haben den Zweck, die Jahresringe des Holzes zu unterbrechen, wodurch die naturgemäss in einem Holzbrett vorhandenen Spannungen sich ausgleichen können und ein Reissen des Brettes vermieden wird.
Zweckmässig werden, wie in Fig. 2 ge zeigt ist, die Schlitze, die nebeneinander zu liegen kommen, abwechslungsweise von bei den Seiten her in das Holzbrett eingesägt.
Die Blindholzlage 1 wird, um eine ge brauchsfertige Tischlerplatte zu erhalten, beidseitig mit Furnierblättern 3 verleimt, wie aus Fig. 2 und 3 ersichtlich ist.
Es ist nicht notwendig, dass die Schlitze der Blindholzlage das Brett in der ganzen Dicke durchsetzen; sie könnten dasselbe auch nur teilweise durchsetzen.
Blockboard. The known blockboard often consist of a blind wood layer, which is provided on one or both sides with veneer sheets. The quality of the blind wood layer is important here, as this is decisive for the strength of the panel.
While the blind wood layer of known blockboard consists of wooden sticks glued together, whereby the flatness of the plate depends on the width of the glued together sticks, in the blockboard according to the present invention the blind wood layer consists of a coherent wooden board, which has at least one side with slots running in the direction of the grain of the wood is provided. This eliminates the annoying and time-consuming gluing of wooden sticks,
while you can still get a tension-free and well-sealed joiner's board.
On the accompanying drawing, an embodiment of the subject invention is illustrated. Fig. 1 shows a blind wood location in the diagram.
Fig. 2 shows a longitudinal section through a finished blockboard, and Fig. 8 shows an end view of such a plate. The one in Fig. 1 shown blind wood layer 1 consists of an uninterrupted continuous wooden board, as such is sawn from tree trunks. In this board several parallel rows of slots are arranged in the direction of the fibers.
Such a row of slots has a number of slots 2 lying one behind the other, which pass through the entire board thickness, and which are offset from the slots of the adjacent slot rows. These rows of slots, which are arranged at relatively small intervals (approx. 8 mm) from each other, have the purpose of interrupting the annual rings of the wood, so that the tensions naturally present in a wooden board can be balanced out and the board is prevented from tearing.
Appropriately, as shown in Fig. 2, the slots that come to lie next to each other, alternately sawn from the sides in the wooden board.
The blind wood layer 1 is, in order to obtain a ready-to-use blockboard, glued on both sides with veneer sheets 3, as can be seen from FIGS. 2 and 3.
It is not necessary for the slots in the blind wood layer to penetrate the entire thickness of the board; they could only partially enforce it.
