Description

  

  Verfahren zur Herstellung von porösen     Mittelplatten.       Es ist bekannt, für     Sperrholzarbeiten,     insbesondere Türen, poröse     Mittelplatten    zu  verwenden, welche gewellte Elemente auf  weisen.  



  Beim Verfahren zur     Herstellung,    von po  rösen Mittelplatten gemäss der Erfindung  werden in wechselnder Folge Verbindungs  elemente, z. B. flache Verbindungselemente  und Rohrlagen, fest zu einem Block verei  nigt, welcher nachher quer zu den Rohren in  Platten     geschnitten        wird.     



  Auf diese Weise lassen sich     Mittelplatten     herstellen, welche gegenüber den bekannten  mit gewellten Elementen wesentlich grössere  Stabilität besitzen, indem der Rohrquer  schnitt     günstigere    statische Verhältnisse  ergibt.  



  Die     Zeichnung    dient zur Erklärung eines  Durchführungsbeispiels dieses Verfahrens  und eines Ausführungsbeispiels einer nach  diesem Verfahren hergestellten, ebenfalls Er  findungsgegenstand bildenden Mittelplatte.  



       Fig.    1 zeigt ein Eckstück einer Mittel  platte in Frontansicht;         Fig.    2 ist eine Oberansicht zu     Fig.    1.  Es     bezeichnet    1 die zum Beispiel aus       Furnieren    bestehenden, zueinander gleich  gerichteten flachen     Verbindungselemente.     Zwischen je zwei benachbarten Verbindungs  elementen 1     befindet    sich eine Rohrlage 2,  die zum Beispiel aus aneinander gefügten  Kartonrohren von einheitlichem Durchmes  ser besteht.

   Dadurch     sind    zueinander par  allele     'Materiallagen    gebildet, die miteinan  der verleimt und somit fest miteinander       bezw.    zu einem Block vereinigt sind.  



  Ein auf diese Weise gebildeter, z. B.  quadratischer Block, wird     in    der Folge quer  zu den Rohren     in    Platten von ihrem Ver  wendungszweck entsprechender Dicke ge  schnitten, wie in     Fig.    2     beispielsweise    durch  die     strichpunktierte    Linie     A-A    angegeben.  Die Frontseiten der so hergestellten     Mittel-          platten    werden     in    der Folge durch Furniere  überdeckt.  



  Durch die zylindrischen Rohre, welche  in ein und derselben Rohrlage     bezw.    Einzel  element unmittelbar und     in    bezug auf zu-      einander benachbarte Rohrlagen mittelbar  aneinander liegen, wird der Platte hohe  Druckfestigkeit gegeben, und ein Biegen so  wie Verziehen der Platte unmöglich ge  macht.  



  Für die Einzelelemente der Platte kom  men verschiedene Materialien in - Betracht.  So zum Beispiel können,     statt    Rohre aus       Karton    (Pappe) solche aus Holz verwendet  werden. Die Herstellung solcher Holzrohre  geschieht maschinell. wozu unter     ZVärme-          einfluss    gedämpfte, weiche     Holzplatten    ver  wendet werden, die auf Spindeln, welche  einen     Achsialschlitz    zum Einsetzen der  Holzplatte haben, rund gewickelt werden.  Gegebenenfalls könnten die Rohr in bezog  auf benachbarte Rohrlagen auch zueinander  versetzt angeordnet werden.



  Process for the production of porous middle plates. It is known to use porous middle panels for plywood work, especially doors, which have corrugated elements.



  In the method of manufacture of porous middle panels according to the invention, connecting elements such. B. flat fasteners and pipe layers, firmly united to form a block, which is then cut across the pipes in plates.



  In this way, middle plates can be produced which have much greater stability than the known ones with corrugated elements, in that the pipe cross-section results in more favorable static conditions.



  The drawing serves to explain an implementation example of this method and an embodiment of a manufactured according to this method, also he subject of the invention forming center plate.



       Fig. 1 shows a corner piece of a center plate in front view; FIG. 2 is a top view of FIG. 1. 1 denotes the flat connecting elements, which consist, for example, of veneers and are aligned in the same direction. Between every two adjacent connecting elements 1 there is a pipe layer 2, which consists, for example, of joined cardboard pipes of a uniform diameter.

   As a result, par allelic layers of material are formed which are glued together and thus firmly to one another. are united in one block.



  A formed in this way, e.g. B. square block, is subsequently cut across the tubes in plates of their intended use Ge corresponding thickness, as indicated in Fig. 2, for example, by the dash-dotted line A-A. The front sides of the middle panels produced in this way are then covered by veneers.



  Through the cylindrical pipes, which BEZW in one and the same pipe layer. If individual elements lie directly against each other and indirectly with respect to adjacent pipe layers, the plate is given high compressive strength and bending and warping of the plate are impossible.



  Various materials can be used for the individual elements of the panel. For example, instead of tubes made of cardboard, tubes made of wood can be used. The manufacture of such wooden pipes is done by machine. For this purpose, soft wooden panels that are dampened under the influence of heat are used, which are wound round on spindles that have an axial slot for inserting the wooden panel. If necessary, the tubes could also be arranged offset to one another with respect to adjacent tube layers.
