Description
Zwischenplatte zur Entlastung von Schraubenbolzen bei Holzverbindungen. Zur Entlastung der Schraubenbolzen bei Holzverbindungen werden Zwischenplatten verwendet, die aus Gußeisen bestehen und beiderseits einen Randring besitzen. Diese vollständig starre gußeiserne Zwischenplatte erschwert den festen Zusammenschluß der zu verbindenden Holzteile, wenn letztere nicht mit entsprechenden Aussparungen versehen sind. Die den Gegenstand der Erfindung bildende Zwischenplatte besteht aus einem Blech mit mehreren um den Bolzen laufenden geschlossenen Wellungen. Durch die Anwendung dieser, eher etwas nachgiebigen Zwischenplatte können die Holzteile ohne verschwächende Aussparungen bei festem Anziehen der Schraube in besserer und leichterer Weise näher aneinander gebracht werden, als es die ganz unnachgiebige gußeiserne Zwischenplatte zuläßt.Intermediate plate to relieve screw bolts in wood connections. Intermediate plates are used to relieve the screw bolts in wood connections. which are made of cast iron and have an edge ring on both sides. This completely Rigid cast-iron intermediate plate makes it difficult to secure the joint to be connected Wooden parts, if the latter are not provided with appropriate recesses. the The object of the invention forming intermediate plate consists of a sheet with several closed corrugations running around the bolt. By applying this, The wooden parts can rather be somewhat flexible intermediate plate without weakening them Recesses closer in a better and easier way when tightening the screw firmly be brought together than the very unyielding cast-iron intermediate plate allows.
Da die neue Zwischenplatte einen Massengegenstand darstellt, ergibt ihre Herstellung durch Pressen gegenüber den durch Gießen erzeugten bekannten Zwischenplatten die in Vereinfachung und Verbilligung der Herstellung bestehenden Vorteile.Since the new intermediate plate is a mass item, results their production by pressing compared to the known intermediate plates produced by casting the advantages of simplifying and making manufacturing cheaper.
Obwohl die Zwischenscheibe aus Blech be. steht, vermag sie doch infolge der Wellungen einem starken Seitendruck zu widerstehen, so daß der Zweck, den Schraubenbolzen von einem solchen Druck zu entlasten, in bester Weise erreicht wird.Although the intermediate plate is made of sheet metal. it is able to do so as a result of the corrugations to withstand a strong side pressure, so that the purpose of the screw bolt relieving such pressure is achieved in the best possible way.
Ein Ausführungsbeispiel der neuen Zwischenplatte ist auf der Zeichnung dargestellt. Fig. x und z zeigen die Zwischenplatte in Schnitt und Aufsicht; Fig. 3 zeigt einen mit der Zwischenplatte versehenen Holzverband. Die dargestellte Zwischenplatte besteht aus einem quadratischen Blech a, welches in der Mitte mit einem Loch b für den Schraubenbolzen und mit konzentrisch zu diesem angeordneten Wellungen versehen ist, die, mit Ausnahme der äußeren Wellung, in sich geschlossen sind.An embodiment of the new intermediate plate is shown in the drawing shown. FIGS. X and z show the intermediate plate in section and top view; Fig. 3 shows a wooden structure provided with the intermediate plate. The illustrated intermediate plate consists of a square sheet a, which is in the middle with a hole b for the screw bolt and provided with corrugations arranged concentrically to this which, with the exception of the outer corrugation, are self-contained.
Wie aus Fig. 3 ersichtlich, werden beim Verbinden zweier Holzteile c und d durch den Schraubenbolzen e beim AnziehenderSchraubenmutter f die Wellungen der auf den Schraubenbolzen gesteckten und zwischen den Holzteilen befindlichen Zwischenscheibe a in die Holzteile allmählich hineingepreßt. Die Wellungen greifen dann gleichmäßig in beide Holzteile ein.As can be seen from Fig. 3, when connecting two wooden parts c and d through the screw bolt e while tightening the screw nut f the corrugations the one placed on the screw bolt and located between the wooden parts Intermediate disk a gradually pressed into the wooden parts. The corrugations grip then evenly into both pieces of wood.
DieZwischenscheibe kann anstatt der quadratischen auch eine kreisrunde, ovale, dreieckige oder sonst geeignete Umrißform haben, ebenso können auch die Wellungen anstatt kreisringförmig anders geformt sein.Instead of the square one, the intermediate washer can also be a circular, oval, triangular or otherwise suitable outline shape, as can the corrugations be shaped differently instead of a circular ring.
In gewissen Fällen brauchen nicht alle Wellen in sich geschlossen um den Bolzen zu laufen. Das ist beispielsweise der Fall bei Zwischenplatten mit eckiger Umrißform, wie die auf der Zeichnung dargestellte, bei welcher die äußere Welle unterbrochen ist.In certain cases not all waves need self-contained to run the bolt. This is the case, for example, with intermediate plates with angular outline, like the one shown in the drawing, in which the outer Wave is interrupted.
