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.
