Description
Verbindung zweier Hölzer durch gebogene, in voller Breite offene Dübel. Die Erfindung betrifft eine Holzverbindung, bei der in die Berührungsflächen der anzuschließenden Hölzer Nuten eingearbeitet «-erden, in die hierzu passend gebogene, in voller Breite offene Dübel derart eingesetzt werden, daß sie mir über einen Teil der Querschnittbreite der angeschlossenen Stäbe, also nicht bis zu den seitlichen Begrenzungsflächen reichen.Connection of two pieces of wood using curved, full-width open dowels. The invention relates to a wood connection in which in the contact surfaces of to be connected wood grooves incorporated "-earth, in the suitably curved, full-width open dowels are used in such a way that they mine over a part the cross-section width of the connected bars, i.e. not up to the lateral ones Boundary surfaces are sufficient.
Der Vorteil dieser Holzverbindung besteht darin, daß das auf Leibungsdruck unmittelbar beanspruchte Vorholz und die beim Kippen des Dübels gedrückten Nutengrturdfläclien von meistenteils gezogenen Holzfasern ringsum eingeschnürt und so am seitlichen Ausweichen und Ausknicken verhindert sind. Ferner wird durch diese das Vorholz einschließenden Holzteile die Scherfläche am Vorholz vergrößert. Gegenüber den bekannten Voll- und Ringdübeln haben die nach der Erfindung ausgebildeten Dübel den Vorzug, daß sie sparsamer im Materialverbrauche sind und enger gesetzt werden dürfen, wodurch die ganze Dübelverbindung kürzer wird. Gegenüber den über die ganze Stabbreite geführten gebogenen, in voller Breite offenen Dübeln hat der Erfindungsgegenstand außer den genannten Vorzügen noch den, daß er bei gleicher Länge stärker abgebogen wird, wodurch eine für die Aufnahme des Dübelkippmomentes günstigere Konstruktionshöhe entsteht, und daß die Schwächung des angeschlossenen Stabes durch den Nuteneinschnitt geringer wird.The advantage of this wood connection is that the pressure on the reveal Forewood that is directly stressed and the grooved mortar surfaces that are pressed when the dowel is tilted constricted all around by mostly drawn wood fibers and so on the side Evasion and buckling are prevented. Furthermore, this enclosing the forewood Wood parts the shear surface on the forewood increased. Compared to the well-known full and Ring dowels, the dowels designed according to the invention have the advantage that they Are more economical in material consumption and may be set closer, which means that the whole dowel connection becomes shorter. Compared to the ones that run across the entire width of the bar The subject of the invention also has curved, full-width open dowels mentioned advantages still that it is bent more strongly with the same length, whereby a construction height that is more favorable for absorbing the dowel tilting moment is created, and that the weakening of the connected rod by the groove incision is less will.
Die Dübel nach der Erfindung können aus jedem beliebigen biegungsfesten Baustoffe, z. B. -Metall, Hartholz usw., bestehen. Die Linienführung der Abbiegung kann verschieden sein. Sie kann eine stetig gekrümmte Kurve oder aus mehreren Kurven verschiedener Krümmung oder aus mehreren geraden oder aus geraden und krummen Strecken zusammengesetzt sein.The dowels according to the invention can be made of any bending resistant Building materials, e.g. B. -Metal, hardwood, etc. exist. The lines of the turn can be different. It can be a continuously curved curve or made up of several curves of various curvatures or of several straight lines or of straight and curved stretches be composed.
Die Dübel nach der Erfindung können in gleichem Umfange wie die bekannten Dübelformen im Holzbau verwendet werden, also z. B. zur Verlaschung von Stößen, zur Ausbildung von Fachwerkknotenpunkten und -gelenken, zur Herstellung verdübelter Balken usw.The dowels according to the invention can be used to the same extent as the known ones Dowel shapes are used in timber construction, so z. B. for lashing shocks, for the formation of truss nodes and joints, for the production of doweled ones Bars etc.
Die Zeichnung zeigt beispielsweise in Abb. i und a einen durch Laschen gedeckten Stoß mit 8 Halbkreisdübeln, Abb. 3 und .1 den Anschluß zweier Fachiverkstäbe an einen Gurtstab mit zwei parabelförmig gebogenen Dübeln, Abb. 5 bis i z verschiedene Formen von Dübelabbiegungen, Abb. 1z bis 16 verschiedene Dübelquerschnitte.The drawing shows, for example, one by tabs in Fig. I and a covered joint with 8 semicircular dowels, Fig. 3 and .1 the connection of two specialist rods to a chord with two parabolic curved dowels, Fig. 5 to i z different Forms of dowel bends, Fig. 1z to 16 different dowel cross-sections.
Diese Dübelquerschnitte können über die ganze Dübellänge gleichbleibend sein oder untereinander wechseln, z. B. kann ein im Scheitel mit hochkantigem Rechteckquerschnitt (Abb. 1a) ausgebildeter Dübel nach den Dübelenden hin in einen flachen Rechteckquerschnitt oder in einen kreuzförmigen Querschnitt (Abb. 15) übergehen.These dowel cross-sections can be constant over the entire length of the dowel be or alternate with each other, z. B. can be one in the apex with an edgewise rectangular cross-section (Fig. 1a) formed dowel towards the dowel ends in a flat rectangular cross-section or merge into a cross-shaped cross-section (Fig. 15).
