In Fig. 1 ist eine erfindungsgemäße Verbindung als biegesteife Ecke für positive Momentübertragung entsprechend dem Pfeil Y ausgebildet. Diese Eckverbindung besteht aus zwei auf Gehrung an einer Stoßstelle 12 aneinanderstoßenden Holzbalken 13, 14, die einen Winkel von 90 ° einschließen. In jeder der Holzbalken 13, 14, nahe an der Stoßstelle 12, ist jeweils eine Vollgewindeschraube 15 parallel zur Stoßstellenfläche der beiden Balken 13, 14 von der Außenseite 17, 18 der beiden Balken 13, 14 eingeschraubt. Diese Vollgewindeschrauben 15 dienen dazu, parallel zu den Stoßflächen auftretende Querzugkräfte auf Zug aufzunehmen. An der Außenseite der Eckverbindung ist in jedem der Holzbalken 13, 14 jeweils eine Vollgewindeschraube 19, 20 in einem Winkel von 67 ° zur Holzfaserlängsrichtung eingeschraubt. Hierbei liegt der Kreuzungspunkt der beiden Vollgewindeschrauben 19, 20 insbesondere in der Stoßstelle 12. Diese Vollgewindeschrauben 19, 20 sind auf Druck belastet. Hierdurch wird in der erfindungsgemäßen Eckverbindung der Druckkontaktpunkt vorgegeben und die Vollgewindeschrauben 19, 20 bilden den Lastpfad für die Versteifung. Zudem ist vorzugsweise auf der Innenseite der Eckverbindung jeweils eine Vollgewindeschraube 21 unter einem Winkel von 45 ° zur Faserrichtung von der Außenseite des jeweiligen Balkens 13, 14 her eingeschraubt, die jeweils unmittelbar vor der Außenseite des anderen Balkens 14, 13 endet. Diese Vollgewindeschrauben 19 nehmen die in dem Bereich auftretende Zugspannung auf und bilden somit ein Widerlager für die Zugkräfte, so dass die biegesteife Ecke in diesem Bereich zusammengehalten wird. Weiterhin ist es zweckmäßig, wenn im Bereich der Innenseite der erfindungsgemäßen Eckverbindung in jedem der Balken 13, 14 eine von der Stoßstelle 12 ausgehende, etwa parallel zur Faserlängsrichtung des jeweiligen Balkens 13, 14 verlaufende Vollgewindeschraube 22 in diesen eingeschraubt ist. Diese beiden Vollgewindeschrauben 22 dienen ebenfalls zur Zugkraftverteilung im Innenbereich der Eckverbindung.In Fig. 1 a connection according to the invention is formed as a rigid corner for positive moment transfer according to the arrow Y. This corner joint consists of two mitred at a joint 12 adjacent wooden beams 13, 14, which enclose an angle of 90 °. In each of the wooden beams 13, 14, close to the joint 12, a full-threaded screw 15 is parallel to the joint surface of the two beams 13, 14 of the outer side 17, 18 of the two beams 13, 14 screwed. These full-thread screws 15 serve to absorb transverse tensile forces occurring parallel to the abutment surfaces on train. On the outside of the corner joint in each of the wooden beams 13, 14 are each a full-threaded screw 19, 20 screwed at an angle of 67 ° to the wood fiber longitudinal direction. In this case, the point of intersection of the two full-thread screws 19, 20 lies in particular in the joint 12. These full-thread screws 19, 20 are loaded under pressure. As a result, the pressure contact point is specified in the corner connection according to the invention and the full-thread screws 19, 20 form the load path for the stiffening. In addition, preferably on the inside of the corner joint in each case a full-threaded screw 21 is screwed at an angle of 45 ° to the fiber direction from the outside of the respective beam 13, 14, which ends immediately in front of the outside of the other beam 14, 13. These full-thread screws 19 take the occurring in the area Tensile stress and thus form an abutment for the tensile forces, so that the rigid corner is held together in this area. Furthermore, it is expedient if in the region of the inside of the corner joint according to the invention in each of the beams 13, 14 an outgoing from the joint 12, approximately parallel to the fiber longitudinal direction of the respective beam 13, 14 extending full-threaded screw 22 is screwed into this. These two full-thread screws 22 are also used for tensile force distribution in the interior of the corner joint.

Im Unterschied zur Ausbildung gemäß Fig. 1 ist die erfindungsgemäße biegesteife Eckverbindung gemäß Fig. 2 für die Übertragung eines Momentes in Pfeilrichtung Z, d. h. einem negativen Moment ausgebildet. Hierbei ist auf der Innenseite der erfindungsgemäßen Eckverbindung nur eine Vollgewindeschraube 21a im Winkel von 45 ° zur Faserlängsrichtung eingebohrt, die in diesem Belastungsfall Druckkräfte aufnimmt. An der Außenseite der Eckverbindung sind in jedem der Holzbalken 13, 14 zwei parallel verlaufende Vollgewindeschrauben 19a, 20a eingeschraubt, die hier für eine optimale Zugkraftverteilung dienen. Parallel zur Stoßstellenfläche der beiden Balken 13, 14 sind von der Innenseite der Eckverbindung her Vollgewindeschrauben 15a eingebohrt, die in diesem Fall zur Aufnahme von Druckkräften in diesem Bereich dienen. Durch die erfindungsgemäße Anordnung der Vollgewindeschrauben wird insbesondere der Lastpfad für die Druckübertragung vorgegeben, d. h. insbesondere durch die Vollgewindeschrauben 19a, 20a und 15a wird eine Druckkraftverstärkung bewirkt.In contrast to the training according to Fig. 1 is the inventive rigid corner joint according to Fig. 2 for the transmission of a moment in the direction of arrow Z, that is formed a negative moment. Here, on the inside of the corner joint according to the invention only a full-threaded screw 21a is drilled at an angle of 45 ° to the fiber longitudinal direction, which receives pressure forces in this load case. On the outside of the corner joint, two parallel full-thread screws 19a, 20a are screwed into each of the wooden beams 13, 14, which serve here for optimum tensile force distribution. Parallel to the abutment surface of the two beams 13, 14 are screwed from the inside of the corner connection fro full thread screws 15a, which serve in this case to absorb pressure forces in this area. The inventive arrangement of the full-thread screws in particular the load path for the pressure transmission is specified, ie in particular by the full-thread screws 19a, 20a and 15a, a compression force enhancement is effected.

Durch die erfindungsgemäße Ausgestaltung der verschiedenen Verbindungen sind diese deutlich höher belastbar als vergleichbare traditionelle Verbindungsarten. Die auftretenden Kräfte werden unter deutlich geringeren Verformungen abgetragen, wobei insbesondere auch die bleibenden Verformungen infolge Schlupf stark reduziert werden. Die erfindungsgemäßen Verbindungen sind deutlich einfacher herzustellen, und zwar mit weniger Material und Arbeitsaufwand. Zudem lassen sich diese erfindungsgemäßen Verbindungen konstruktiv so auslegen, dass durch die Anordnung der Schrauben in der Gesamtkonfiguration ein quasi-duktiles Tragverhalten der Fügung mit angekündigtem Versagen durch sichtbare Deformationen induziert wird.Due to the inventive design of the various compounds they are significantly higher load capacity than comparable traditional types of connections. The occurring forces are removed under much lower deformations, in particular, the permanent deformations due to slip are greatly reduced. The compounds of the invention are much easier to produce, with less material and labor. In addition, these compounds of the invention can constructively interpret so that the arrangement of the screws in the overall configuration, a quasi-ductile load bearing behavior of the joint with announced failure is induced by visible deformations.

Der Querschnittsabmessungen der Balken 13, 14 bei der erfindungsgemäßen biegesteifen Ecke haben eine Abmessung von 14 x 36 cm und der Verlauf der einzelnen Vollgewindeschrauben ist derart, dass sie an ihren dem Schraubenkopf gegenüberliegenden Ende aus den Trägem im eingeschraubten Zustand nicht austreten und möglichst kurz vor der Oberfläche des jeweiligen Balkens enden. Vorzugsweise werden Schrauben mit 8 mm Durchmesser verwendet. Die Schrauben 21 sind gewindestangenmäßig ausgebildet und besitzen einen Durchmesser von 16 mm.The cross-sectional dimensions of the beams 13, 14 in the bending corner according to the invention have a dimension of 14 x 36 cm and the course of the individual full-thread screws is such that they do not escape at their opposite end of the screw from the carriers in the screwed state and as close to the Surface of the respective bar ends. Preferably, 8 mm diameter screws are used. The screws 21 are formed Gewindestangenmäßig and have a diameter of 16 mm.

Auf Grund der erfindungsgemäßen Anordnung sind die Schrauben im Wesentlichen dem Kraftschluss entsprechend angelegt, so dass sie vorwiegend normalkraftbeansprucht sind. Die erfindungsgemäßen Stoßverbindungen sind deutlich höher belastbar als vergleichbare traditionelle Verbindungsarten. Die Kräfte werden unter deutlich geringeren Verformungen abgetragen, wobei insbesondere auch die bleibenden Verformungen infolge der Verbindungsmittel stark reduziert werden. Zudem ergibt sich eine deutlich einfachere Herstellbarkeit mit weniger Material- und Arbeitsaufwand.Due to the arrangement according to the invention, the screws are essentially applied according to the frictional connection, so that they are predominantly normal force. The butt joints according to the invention are significantly more resilient than comparable traditional types of connection. The forces are removed under significantly lower deformations, and in particular the permanent deformations due to the connecting means are greatly reduced. In addition, a much easier manufacturability results with less material and labor.
