Description
Sperrholzplatte Die Erfindung betrifft Sperrholzplatten mit aus Stäben zusammengesetzter Mittellage. Kennzeichen der Erfindung ist, daß die Stäbe der llrlittellage durch Dübel vereinigt sind.Plywood Panel The invention relates to plywood panels comprising rods composite middle layer. A characteristic of the invention is that the rods of the llrlittellage are united by dowels.
Bei den bekannten Sperrholzplatten mit asu Stäben zusammengesetzter Mittellage hat man entweder die einzelnen Stäbe miteinander verleimt oder durch Feder und Nut in rechteckiger oder Schwalbenschwanzform verbunden.In the case of the known plywood panels with asu bars composite The middle layer is either glued together or through the individual bars Tongue and groove connected in a rectangular or dovetail shape.
Gegenüber den Platten mit verleimten Stäben hat die verdübelte Platte den Vorteil, daß die Vereinigung der Stäbe der Mittellage vollkommen auf trockenem Wege erfolgt. Ein Einleimen der Dübel ist nicht erforderlich. Gegenüber den Platten, bei denen die Stäbe durch Nut und Feder vereinigt sind, wird an Material gespart, denn jeder einzelne Stab wird um den Betrag der Feder bei der Herstellung gleichsam verkürzt. Es geht also die Höhe jeder Feder für die Plattenlänge verloren. Außerdem müssen die Nuten und Federn ganz genau bearbeitet werden, während bei Verwendung von Dübeln ein leichtesÜberhobelnan den zu fügendenKanten genügt. Das Einziehen der Dübel selbst vollzieht sich leicht und schnell, weil die Einzelstäbe, in geeigneten Bohrvorrichtungen vereinigt, in Gruppen gebohrt und verdübelt werden können. Dadurch wird die verdübelte Platte gegenüber der mit Nut und Feder versehenen nicht nur billiger, sondern kann auch schneller hergestellt werden.Opposite the panels with glued rods, the dowelled panel has the advantage that the union of the bars of the middle layer completely on dry Ways takes place. It is not necessary to glue in the dowels. Opposite the plates, in which the rods are united by tongue and groove, material is saved, for every single rod is made, as it were, by the amount of the spring shortened. So the height of each spring is lost for the plate length. aside from that the grooves and tongues must be machined very precisely while in use of dowels, a light planing over the edges to be joined is sufficient. Moving in the dowel itself takes place easily and quickly because the individual rods are in suitable Drilling devices can be combined, drilled in groups and pegged. Through this the dowelled plate is not only compared to the one provided with tongue and groove cheaper, but can also be produced more quickly.
Endlich geben die Dübel als solche der Platte eine größere Festigkeit, weil sie wie ein Gerippe in der Platte sitzen.Finally, the dowels as such give the board greater strength, because they sit like a skeleton in the plate.
Es wird nicht verkannt, daß Dübelverbindungen bei Holz längst bekannt sind, doch sind die Vorteile der Verdübelung bei der Herstellung von Sperrholz bisher nicht erkannt worden.It is not overlooked that dowel connections in wood have long been known are, however, the advantages of dowelling in plywood manufacture are so far not recognized.
Auf der Zeichnung ist eine Sperrholzplatte nach der Erfindung in Abb. z mit teilweise abgenommenem Deckfurnier schaubildlich dargestellt.In the drawing, a plywood board according to the invention is shown in Fig. z shown diagrammatically with the face veneer partially removed.
Abb. 2 ist ein senkrechter Schnitt durch die Platte.Fig. 2 is a vertical section through the plate.
Die Platte nach Abb. z und 2 besteht aus den Stäbchen a, die die Mittellage bilden. Die einzelnen Stäbchen sind von beliebiger Länge. Oben und unten sind auf die Stäbchenplatte Furnierplatten b aufgeleimt. Die Stäbe untereinander sind durch Dübel c verbunden.The plate according to Fig. Z and 2 consists of the rods a, which are the middle layer form. The individual sticks are of any length. Up and down are up the chopstick plate veneer plates b glued on. The bars are through Dowel c connected.
Das Verdübeln der einzelnen Stäbe geschieht in einer Vorrichtung. Man legt darin zunächst eine Anzahl Stabreihen übereinander und spannt sie fest. Darauf bohrt man die Dübellöcher und schlägt schließlich die Holzdübel c hinein. Dann wird wieder eine Anzahl Stäbe auf die bereits verdübelten Reihen aufgelegt, festgespannt, gebohrt und unter sich sowohl wie mit den ersten Stabreihen verdübelt. Abb. 2 läßt deutlich erkennen, wie stets einige Reihen durch Dübel vereinigt sind, wobei stets in einer Stabreihe Dübel von beiden Reihengruppen nebeneinander eingreifen. Die fertige verdübelte Platte kann, wenn es nötig ist, um sie genau eben zu machen und ihr eine genaue Stärke zu geben, vor dem Auflegen der Deckplatten abgehobelt werden.The individual rods are dowelled in a device. First you put a number of rows of rods on top of each other and clamp them tight. Then you drill the dowel holes and finally knock in the wooden dowels c. Then a number of bars are placed on the rows that have already been dowelled, clamped, drilled and pegged under them as well as with the first rows of rods. Fig. 2 clearly shows how some rows are always united by dowels, always in a row of rods dowels from both row groups engage next to each other. The finished pegged board can, if necessary, to make it exactly level and to give it an exact thickness, planed off before laying the cover plates will.
