Description
Tischlerplatte. Die Erfindung bezieht sich auf eine Tischlerplatte, z. B. für Türen, Wände und dergl., welche aus zwei Deckplatten mit Holzzwischenlagen aus leistenförmigen, durch Luftkanäle voneinander getrennten Elementen besteht.
Derartige Platten sind an sich bekannt. Sie weisen aber den Nachteil auf, dass die Holzfasern der Deckplatten und der Elemente parallel verlaufen, so dass das durch Auf nahme oder Abgabe von Feuchtigkeit verursachte Ausdehnen und Schwinden der Elemente quer zur Faserrichtung zum Ver winden und Welligwerden der Platten führt.
Dieser Nachteil wird erfindungsgemäss dadurch behoben, dass mindestens ein Teil der leistenförmigen Elemente in bezug auf die Richtung der Holzfasern senkrecht zu den Deckplatten steht.
Beispielsweise Ausführungsformen des Er findungsgegenstandes sind in der beiliegenden Zeichnung dargestellt. Es zeigt: Fig. 1 und 2 Tischlerplatten im Schnitt, deren Elemente aus Sperrholzstreifen mit Hirnholzzwischenlagen bestehen, Fig. 3 eine Tischlerplatte, bei welcher auch die Hirnholzzwischenlagen durch Luft kanäle voneinander getrennt sind, Fig. 4 einen Schnitt nach der LinieIg-IX in Fig. 3.
Gemäss Fig. 1 weist die Tischlerplatte zwei Deckplatten 1 auf, welche aus Furnier, Sperrholz, Holzfaserplatten, Eternit und dergl. bestehen können. Die zwischen die Deck platten 1 eingesetzten und mit ihnen ver leimten Elemente bestehen aus Sperrholz streifen 3 mit Hirnholzzwischenlagen 2, wobei die Holzfasern sowohl der Sperrholzstreifen 3, als auch der Hirnholzzwischenlagen 2 senk recht zur Faserrichtung der Deckplatten 1 verlaufen. Zwischen den Elementen 2, 3 be finden sich Luftkanäle 7.
Diese Platte, bei welcher die Hirnholzatreifen 2 auch weg gelassen werden können, ist infolge der aus den Elementen gebildeten Luftkanäle 7 ausser ordentlich leicht.
Das Ausführungsbeispiel gemäss Fig. 2 unterscheidet sich von dem in Fig. 1 gezeig ten Beispiel dadurch, dass die Hirnholz streifen 2 stärker gewählt sind, so dass beim Verleimen mit den Deckplatten ein stärkerer Druck auf die ganze Platte ausgeübt wer den kann.
Die Platte nach den Fig. 3 und 4 besitzt zwischen den Deckplatten Elemente, welche ebenfalls durch Luftkanäle getrennt sind. Jedes Element besteht aus zwei Hirnholz furnieren 4, zwischen und mit welchen zwei Langholzstreifen 8 derart verleimt sind, dass sie einerseits an die Deckplatten 1 an schliessen, anderseits aber zwischen ihren innern, freien, einander zugewendeten Gegen flächen Luftkanäle 9 offen lassen (vergleiche insbesondere Fig. 3). Durch diese Anordnung wird erreicht, dass die beiden Hirnholz streifen 4 die Deckplatten 1 genau im ur sprünglichen Abstand halten, ohne dass durch Aufnahme oder Abgabe von Feuchtigkeit Ausdehnung oder Schwindung auftritt.
Die Langholzlatten oder -Streifen 8 geben der Platte die nötige Festigkeit, halten die Hirn holzlatten 4 zusammen und stützen die DECk- platten 1, während gleichzeitig eine genügend grosse Oberfläche für die Leimverbindung zwischen den Deckplatten 1 und den Ele menten 4, 8 geschaffen wird.
Es ist bei dieser Konstruktion auch mög lich, die nebeneinander angeordneten Ele mente in Gruppen zusammenzufassen und diese Gruppen ihrerseits wiederum durch Luftzwischenräume zu trennen.
Für sehr leichte Platten können die Ele mente aus Sperrholzstreifen bestehen.
Blockboard. The invention relates to a blockboard, e.g. B. for doors, walls and the like. Which consists of two cover plates with wooden interlayers from strip-shaped, separated by air ducts elements.
Such plates are known per se. However, they have the disadvantage that the wood fibers of the cover plates and the elements run parallel, so that the expansion and shrinkage of the elements caused by the absorption or release of moisture across the fiber direction leads to the plates becoming twisted and wavy.
According to the invention, this disadvantage is eliminated in that at least some of the strip-shaped elements are perpendicular to the cover plates in relation to the direction of the wood fibers.
For example, embodiments of the subject invention He are shown in the accompanying drawings. It shows: Fig. 1 and 2 blockboard in section, the elements of which consist of plywood strips with end grain intermediate layers, Fig. 3 a blockboard in which the end grain intermediate layers are separated from each other by air ducts, Fig. 4 is a section along the line Ig-IX in Fig 3.
According to FIG. 1, the blockboard has two cover plates 1, which can be made of veneer, plywood, wood fiber boards, Eternit and the like. The elements between the cover plates 1 used and glued with them consist of plywood strips 3 with end-grain intermediate layers 2, the wood fibers of both the plywood strips 3 and the end-grain intermediate layers 2 run perpendicular to the fiber direction of the cover plates 1. There are air ducts 7 between the elements 2, 3 be.
This plate, in which the end grain tires 2 can also be left out, is extremely light due to the air ducts 7 formed from the elements.
The embodiment according to FIG. 2 differs from the example shown in FIG. 1 in that the end-grain strips 2 are chosen to be stronger, so that when gluing with the cover plates, greater pressure is exerted on the whole plate.
The plate according to FIGS. 3 and 4 has elements between the cover plates which are also separated by air ducts. Each element consists of two end-grain veneers 4, between and with which two long wood strips 8 are glued in such a way that on the one hand they close to the cover plates 1, but on the other hand leave air ducts 9 open between their inner, free, opposing surfaces (compare in particular Fig . 3). This arrangement ensures that the two end grain strips 4 keep the cover plates 1 exactly at the original distance without expansion or shrinkage occurring due to absorption or release of moisture.
The long wood slats or strips 8 give the board the necessary strength, hold the brain wood slats 4 together and support the DECk boards 1, while at the same time a sufficiently large surface for the glue connection between the cover boards 1 and the elements 4, 8 is created.
With this construction, it is also possible, please include the elements arranged next to each other to be combined in groups and these groups in turn to be separated by air gaps.
For very light panels, the elements can consist of strips of plywood.
