Description

Aus mehreren Brettstreifen ohne Verleimung, zusammengefügte Mittellage für Sperrholzplatten Die Erfindung betrifft eine aus mehreren Brettstreifen ohne Verleimüng zusammengefügte Mittellage für Sperrholzplatten. min beiderseitigen gegeneinander versetzten, ungefüllt bleibenden Einschnitten bis über deren Mitte in Faserrichtung, und ist dadurch gekennzeichnet, daß die Brettstreifen nur durch Wellennägel miteinander verbunden sind.Made of several board strips without gluing, joined middle layer for plywood panels The invention relates to one of several board strips without Glued-together middle layer for plywood panels. min mutual against each other staggered, unfilled incisions up to their middle in the direction of the grain, and is characterized in that the board strips with each other only by corrugated nails are connected.

Es ist bereits bekannt, die Brettstreifen dieser Mittellage durch Schwalbensch",vanzverbindung ;miteinander zu vereinigen oder aber durch Dübel. Beide Verbindungen ergeben, da die Verleimung vermieden werden muß, eine Festlegung der Brettstreifen gegeneinan.der nur in einer Richtung, und zwar quer zur Schwalbenschwanzverbindung oder quer zu dem Dübel, nicht aber in Richtung der Schwalbenschwanzverbindung oder in Richtung der Dübel. Die Schwalbenschwanzverbindung erfordert außerdem einen verhältnismäßig großen Aufwand an Baustoff, da die Höhe des Schwalbenschwanzes von der Baulänge verlorengeht. Weiter ,erfordern die beiden Verbindungen Spezialmaschinen zu ihrer Herstellung.It is already known that the board strips through this middle layer Schwalbensch ", vanz connection; to be united with each other or by dowels. Both Connections result, since the gluing must be avoided, a definition of the Board strips facing each other only in one direction, namely at right angles to the dovetail joint or across the dowel, but not in the direction of the dovetail connection or towards the dowel. The dovetail connection also requires a relatively large amount of building material, since the height of the dovetail depends on the overall length get lost. Furthermore, the two connections require special machines for their Manufacturing.

Die erfindungsgemäße Verbindung vermeidet die obeai .angeführten Nachteile und ermöglicht das, Herstellen der Mittellage zu (einem erheblich geringeren Preis, als ges bei Anwendung der bekannten Verbindungsarten möglich ist.The connection according to the invention avoids the disadvantages mentioned above and enables the production of the middle layer (at a considerably lower price, than total is possible when using the known types of connection.

Schließlich kann bei Anwendung der Wellennägel minderwertiges Holz, z. B. Seitenbretter, verwendet werden, weil die Jahresringe nicht aufrecht zu stehen brauchen.Finally, when using the corrugated nails, inferior wood, z. B. side boards, are used because the annual rings do not stand upright to need.

Infolge der Festlegung der Brettstreifen in Längs- und Querrichtung können bei Anwendung dieser neuen Mittellage für das Herstellen der Sperrholzplatten Furniere geringerer Stärke benutzt werden, als @es bisher üblich ist, also auch insofern eine Baustoffersparnis erzielt werden. An sich sind Wellennägel zur Verbindung von Holzteilen hekannt.As a result of the definition of the board strips in the longitudinal and transverse direction can when using this new middle layer for the production of the plywood panels Veneers of a lower thickness than has been used so far, so too to the extent that building material savings can be achieved. In themselves, corrugated nails are used to connect known from wooden parts.

Die Zeichnung veranschaulicht ein Ausführungsbeispiel des Erfindungsgegenstandes. Abb. i zeigt eine Draufsicht auf die Mittellage.The drawing illustrates an embodiment of the subject matter of the invention. Fig. I shows a top view of the middle layer.

Abb. 2 ist ein Schnitt gemäß der Geraden II-II der Abb. i, Abb.3 ein Schnitt gemäß der Geraden III-III der Abb. i.Fig. 2 is a section along the line II-II of Fig. I, Fig.3 a Section along the straight line III-III in Fig. I.

Die Sperrholzplatte besteht, wie üblich, aus einer Mittelhage i und zwei Furnieren 2 und 3. Die Mittellage ist aus mehreren Brettstreifen ja, ib, Je , id usw. je nach .der gewünschten Abmessung zusammengesetzt. Die einzelnen Brettstreifen sind nicht miteinander verleimt, sondern werden nur durch an sich bekannte Wellennägel. zusammengehalten.The plywood sheet consists, as usual, of a middle layer i and two veneers 2 and 3. The middle layer is composed of several board strips ja, ib, je , id etc. depending on the desired dimensions. The individual board strips are not glued together, but are only made using well-known corrugated nails. held together.

Die einzelnen Brettstreifen i-, ib usw. werden vor dem Zusammensetzen in an sich bekannter Weise mit in Faserrichtung verlaufenden, bis, über deren Mitte reichenden Nuten 5 versehen, z. B. durch einen Sägeschnitt o. dgl. Die Nuten sollen ungefüllt bleiben und werden deshalb beim :oder auch `nach dem Schneiden sorgfältig ausgeblasen.The individual board strips i-, ib etc. are before assembling in a manner known per se with extending in the direction of the grain, to, over the middle reaching grooves 5 provided, for. B. by a saw cut o. The like. The grooves should remain unfilled and are therefore carefully used when: or after cutting blown out.

Damit die Nuten auch nach dein Aufbringen .der Furniere 2 und 3 leer bleiben, also nicht mit Leim gefüllt werden, wird der Leim nur auf die Furniere aufgetragen.So that the grooves are empty even after the veneers 2 and 3 have been applied stay, so don't be filled with glue, the glue will only apply to the veneers applied.
