Description

Mittellage für Sperrholzplatten Die Erfindung betrifft eine werkstoffsparende ;Mittellage aus Holz oder Holzfaserstoff zum Herstellen von Hohlraumplatten für Tischler- und Bauzwecke.Middle layer for plywood panels The invention relates to a material-saving ; Middle layer made of wood or wood fiber for the production of cavity panels for Carpentry and building purposes.

Unter den bekannten werkstoffsparenden Mittellagen befinden sich auch solche aus hochkant gestellten Holzstreifen oder Flachstäben mit Hohlraumbildung, wobei aber die Stablamellen auf in der Herstellung verhältnismäßig schwierige Art von vornherein miteinander zu einem sperrigen Gitterstabgebilde von unveränderlicher Breite miteinander verleimt sind. Bekannt sind ferner auch Holzplatten mit einem durch Sägeschnitte gebileleten Gitterstabwerk, dessen Stabenden wechselseitig zusammenhängen.Among the well-known material-saving middle layers are also those made of upright wooden strips or flat bars with cavities, but the rod lamellas are relatively difficult to manufacture from the outset with each other to form a bulky bar structure that is unchangeable Width are glued together. Also known are wooden panels with a Lattice framework formed by saw cuts, the rod ends of which are mutually connected.

Den bekannten Mittellagen finit Hohlräuinen aus hochkant gestellten Holzstäben gegenüber kennzeichnet sich die Mittellage gemäß der Erfindung durch die Verwendung eines aus Einzelstäben bestehenden, ausziehbaren Flachstabgebildes, dessen Stabenden abwechselnd miteinander verbunden, z. B. verleimt sind.The well-known middle layers of finite cavities made up on edge Opposite wooden bars, the middle layer according to the invention is characterized by the use of a pull-out flat image consisting of individual rods, whose rod ends are alternately connected to one another, e.g. B. are glued.

In der auseinandergezogenen Stellung der -Mittellage gemäß der Erfindung entsteht ein Gitterstabwerk von geringem Eigengewicht niit Zwischenräumen, die beim Aufleimen der Außenplatten auf die 'Mittellage wärinedäinniende Hohlräume ergeben.In the expanded position of the middle layer according to the invention the result is a lattice framework of low weight with gaps that Gluing the outer panels onto the middle layer results in heat-dinning cavities.

Gegenüber den bekannten i@-Iittellagen mit Hohlräumen bietet die Mittellage gemäß der Erfindung die besonderen und wichtigen Vorteile, daß diese Mittellage nach"ihrer Fertigstellung zusammenfedert und so bei der Lagerhaltung und beim Versand nach entfernten Weiterverarbeitungsstellen einen geringeren Raum beansprucht, ferner, je nach Bedarf, auf verschiedene Breite zur Bildung mehr oder minder breiter Hohlräume auseinanderziehbar ist und schließlich auch zur Verarbeitung zu verschieden gel;riiinniten oder gewölbten und sogar kreisrund gebogenen Sperrholzplatten ohne Bruchgefahr verwendbar ist.Compared to the well-known i @ middle layers with cavities, the middle layer offers according to the invention the particular and important advantages that this middle layer after "their completion springs together and so in storage and shipping takes up less space after remote processing points, furthermore, Depending on requirements, to different widths to form more or less wide cavities can be pulled apart and finally also for processing into different gel; riiinniten or curved and even circularly curved plywood panels can be used without the risk of breakage is.

Fig. i zeigt ein Bruchstück einer auseinanderzielibaren -Mittellage vor dein Auseinanderziehen, die in an sich bekannter Wei.#e aus hochkant gestellten, an den Enden alfwechselnd bei i und 2 miteinander verbundenen dünnen Einzelstäben besteht.Fig. I shows a fragment of a center ply that can be aimed apart before your pulling apart, the in itself known white. # e from upright, at the ends alternately at i and 2 thin individual rods connected to one another consists.

Fig.2 veranschaulicht die gleiche -Mittellage wie Fig. i, aber etwas auseinandergezogen, wobei <las Ende 2 des hochkant gestellten Gitterstabes h am Innenstab (t eines z. B. fest zusammengeleimten, eine Randleiste. bildenden Stabbündels z. B. angelehnt ist, während das andere Ende i des Lainellenstabes b mit dein Ende i des Nachbarstabes c fest verbunden, z. B. verleimt ist. Das Ende 2 des Stabes c wiederum ist am --\'ebenstab d befestigt und so fort entsprechend für die Stabpaar° c°-rl, d-e, e-f und die fol`enden Stabpaare an deren Enden 2 bzw. i, so daß in der ausgezogenen Lage des Flachstabgebildes ein Stabgitterwerk nach Art eines Zickzackhandes mit Zwischenräumen entsteht, das verschieden weit attseinandergezogen und auch ohne Bruchgefahr verschieden ,gewölbt werden kann und zum Herstellen von Sperrholzplatten verschiedener Breite, von flachen, gekrümmten, sogar kreisrunden Bauteilen verwendbar ist.Fig.2 illustrates the same central position as Fig. I, but somewhat pulled apart, with <las end 2 of the upright bar h on the inner bar (t of a bundle of bars that is, for example, firmly glued together to form an edge strip z. B. is ajar, while the other end i of the Lainellenstab b with your end i of the neighboring rod c firmly connected, z. B. is glued. The end 2 of the stick c in turn is attached to the - \ 'plane rod d and so on accordingly for the rod pair ° c ° -rl, d-e, e-f and the following pairs of rods at their ends 2 and i, so that in the extended position of the flat image a bar latticework in the manner of a zigzag hand with gaps arises that are drawn to each other to different extents and also without Risk of breakage different, can be arched and used to manufacture plywood panels different widths, can be used from flat, curved, even circular components is.
