Description

Zugfeste Stoßverbindung für frei tragende Holzkonstruktionen. Der Anschluß der auf Zug beanspruchten Verbandhölzer erfolgt bei cler Durchbildung von Binderknotenpunkten meist durch Schraubenbolzen, die quer zur Zugrichtung liegen, infolgedessen auf Biegung und Abscheerung beansprucht werden und oft übermäßig großen Lochwanddruck hervorrufen. Dieser Mangel tritt auch bei sonstigen HoIzverbindungen öfters zutage, z. B. wenn bei in gerader Richtung gestoßencn Verbandhölzern die Zugkraft mittels quer gerichteter Schraubenbolzen auf Längslaschen übertragen wird. Sobald es sich um erhebliche Zugkräfte handelt, haben die üblichen Querbolzen weder die nötige Biegungsfestigkeit noch ist eine genügende Auflagerfläche in der Lochwand bei der geringen Druckfestigkeit des Holzes vorhanden, wobei hinzukommt, daß die zylindrischen Lagerflächen für die Kraftübertragung weniger geeignet sind als ebene. Häufig muß auch der Querbolzen zu nahe am Ende des Zugstabes angeordnet werden, so daß die Lochwand nicht hinreichend gegen Ausscheerung gesichert ist.Tensile butt joint for self-supporting wooden structures. Of the Connection of the tensile stressed bandage wood takes place with the formation of Binder nodes mostly by screw bolts that are perpendicular to the direction of pull, as a result, they are subjected to bending and shearing stress and are often excessively large Cause perforated wall pressure. This defect also occurs with other wood connections often revealed, e.g. B. when in a straight direction encountered wooden bandage the Tensile force is transmitted to longitudinal brackets by means of transversely directed screw bolts. As soon as there are significant tensile forces, the usual cross bolts have neither the necessary flexural strength is still a sufficient support surface in the perforated wall present in the low compressive strength of the wood, with the additional fact that the cylindrical bearing surfaces are less suitable for power transmission than flat ones. Often the cross bolt has to be placed too close to the end of the tension rod, so that the perforated wall is not adequately secured against separation.

Durch die Erfindung soll diesen Übelständen gesteuert werden.The invention is intended to control these inconveniences.

Abb. i zeigt schematisch einen Binder, Abb. 2 und 3 in vergrößertem Maßstabe Ansicht und Schnitt seines Firstknotenpunktes und Abb. q. und 5 eine Seitenansicht und Aufsicht der Stoßverbindung eines beliebigen Untergurtes. Statt der üblichen Querbolzen werden quer durch die auf Zug beanspruchten Hölzer a biegungsfeste, am besten aus Vierkant- oder Profileisen bestehende Widerlagsglieder b geführt, deren ebene Lagerfläche der Druckfestigkeit des Holzes voll entspricht und so weit vom Ende der Hölzer a zurückliegt, daß ein Ausscheren der Lochwand ausgeschlossen ist. Die vorstehenden Enden der Widerlagsglieder b sind so eingerichtet, daß zu beiden Seiten der Hölzer a in deren Längsrichtung Zugglieder c nachstellbar angeschlossen werden können, die an ihrem anderen Ende in gleicher oder ähnlicher Weise, wie z. B. durch die Platten d in Abb. 2 und 3, ihr Widerlager erhalten.Fig. I shows schematically a binder, Fig. 2 and 3 in an enlarged view Scale view and section of its ridge junction and Fig. Q. and Fig. 5 is a side view and supervision of the butt joint of any lower chord. Instead of the usual Cross bolts are bend-resistant across the tensile timber a, on best made of square or profile iron abutment members b out, their level bearing surface fully corresponds to the compressive strength of the wood and so far from The end of the timbers a lies back so that the perforated wall cannot shear out. The protruding ends of the abutment members b are arranged so that to both Sides of the timbers a connected in the longitudinal direction of tension members c adjustable can be that at their other end in the same or a similar manner, such as. B. obtained by the plates d in Fig. 2 and 3, their abutment.

Bei einem geradlinigen Stoß weiden die Stoßflächen, wie Abb, q. und 5 zeigen, zweckmäßig mit Kreuzrippe und -nut e versehen.In the case of a straight joint, the joint surfaces graze, as shown in Fig, q. and 5 show, expediently provided with cross rib and groove e.
