Description
Knotenpunktverbindung für hölzerne Fachwerkträ_ger Im Hauptpatent ¢¢6 z¢8 ist eine Knotenpunktverbindung für hölzerne Fachwerkträger mit in den Gurt eingelassenem Knotenstück beschrieben worden, welche das Merkmal aufweist, daß das Knotenstück aus Beton besteht und daß seine herausragenden Eiseneinlagen zur Übertragung der Zugkräfte aus den Gitterstäben dienen, während die Druckkräfte durch stumpfen Stoß unmittelbar auf das Knotenstück übertragen werden.Junction connection for wooden trusses In the main patent ¢¢ 6 z ¢ 8 is a junction connection for wooden trusses with in the belt recessed node has been described, which has the feature that the The junction is made of concrete and that its protruding iron inlays for transmission serve the tensile forces from the bars, while the compressive forces through butt Impact can be transmitted directly to the node.
Das vorliegende Zusatzpatent betrifft eine weitere Ausbildung und Verbesserung des Gegenstandes des Hauptpatents und besteht darin, daß. die die Zugkräfte der Gitterstäbe aufnehmenden Eisen seitlich haftend an dem Knotenstück anliegen und durch gleichfalls außerhalb .des Knotenstücks liegende Eisen miteinander verbunden sind.The present additional patent relates to a further training and Improvement of the subject matter of the main patent and consists in that. which the tensile forces the bars receiving iron laterally adhere to the node piece and connected to one another by irons which are also outside the knot are.
Die Erfindung ist in der Zeichnung dargestellt, und zwar zeigen: Abb. i einen Untergurtknoten eines hölzernen Fachwerkträgers im Aufriß, Abb. z im Schnitt nach der Linie a-a der Abb. i und Abb.3 im Schnitt nach der Linie ß-ß der Abb. i.The invention is shown in the drawing, namely show: Fig. i a bottom chord knot of a wooden truss in elevation, Fig. z in section according to the line a-a of Fig. i and Fig. 3 in the section according to the line ß-ß of Fig. i.
Ferner zeigen Abb. q, 5 und 6 im Aufriß, in Seitenansicht und im Schnitt nach der Linie ß-ß der Abb. 4. das Eisengerippe des Knotenstücks, gesondert vom Holz und Beton, während Abb. 7, 8 und 9 im Aufriß, in Seitenansicht und im Schnitt nach. Linie ß-ß der Abb. 7 den Betonkörper des Knotenstücks veranschaulichen.Furthermore, Fig. Q, 5 and 6 show in elevation, side view and section according to the line ß-ß in Fig. 4. the iron framework of the knot, separate from Wood and concrete, while Fig. 7, 8 and 9 in elevation, side view and section after. Line ß-ß of Fig. 7 illustrate the concrete body of the junction piece.
In den Zeichnungen ist der übersichtlichkeit wegen angenommen worden, da,ß das Holz hinsichtlich des Betons und des Eisens sowie der Beton im Hinblick auf das Eisen durchsichtig sind.For the sake of clarity, it has been assumed in the drawings that da, ß the wood with regard to the concrete and the iron as well as the concrete with regard to it on the iron are transparent.
In dem dargestellten Knoten schließen sich an den gezogenen, zweiteilig aus zwei Hälften eines Rundholzes bestehenden Untergurt A zwei Fachwerkstäbe an, nämlich der gezogene, aus Hälften eines Rundholzes bestehende Stab D und der gedrückte, aus einem Rundholz bestehende Stab D' - sowie außerdem der gleichfalls aus einem Rundholz bestehende, den Obergurt in der Feldmitte stützende Ständer S.In the illustrated knot, the drawn, two-part join lower chord A consisting of two halves of a round timber to two truss rods, namely the drawn rod D, consisting of halves of a round wood, and the pressed rod D, rod D 'consisting of a round wood - as well as the rod D' also consisting of one Stand p.
Die beiden Halbhölzer des Stabes D werden mittels Flacheisen Y, Y angeschlossen, die an einem Ende mit den beiden Halbhölzern wie bei dem Ausführungsbeiisp;iel des Hauptpatents z. B. durch Rippen y, y und Schrauben z, z in Verbindung gebracht sind und am gegenüberliegenden Ende angenietete Winkeleisen w erhalten. Die Winkeleisen sind durch die an sie angenieteten, quer zumWinkeleisenpaar verlaufenden Flacheisen w' miteinander verbunden, so daß, an diesem Ende ein kastenförmiges Gebilde mit zum Teil durchbrochenen Wänden entsteht, das durch zusätzliche Schalung zu einem der Form des fertigen Knotenstücks X angepa.ßten Formkasten ergänzt wird.The two half-timbers of the rod D are made using flat irons Y, Y connected, which at one end with the two half-timbers as in the embodiment of the main patent z. B. connected by ribs y, y and screws z, z and angle iron w riveted to the opposite end. The angle irons are riveted to them and run across the pair of angle irons w 'connected to one another, so that, at this end, a box-shaped structure with to the Part of openwork walls is created by adding additional formwork to one of the Shape of the finished junction piece X adapted molding box is added.
Im vorliegenden Falle ist die zusätzliche Schalung zum Teil durch Schalungsbrettchen gebildet, welche die Öffnungen der schrägen, von den Winkel- und Flacheisen w, w' gebildeten Wand des Eisenkastens nach unten abschließen und den nach oben aus dem Gurt herausragenden Teil des zu formenden Knotenstücks seitlich abgrenzen und zum Teil durch die Begrenzungsflächen der Holzteile im Gurt, und zwar durch die Innenflächen der beiden Halbhölzer A, A und durch die Stirnfläche -des Holzstücks E, welches mit dem Gurt verzahnt ist und die Resultierende der von den Stäben D, D' und S her auf das Knotenstück X einwirkenden Kräfte auf den Gurt überträgt.In the present case, the additional formwork is partly formed by formwork boards, which close the openings of the inclined wall of the iron box formed by the angle and flat iron w, w 'downwards and laterally the part of the junction piece to be formed protruding upwards from the belt delimit and in part by the boundary surfaces of the wooden parts in the chord, namely by the inner surfaces of the two half-timbers A, A and by the face of the piece of wood E, which is interlocked with the belt and the resultant of the rods D, D ' and S transmits forces acting on the junction piece X to the belt.
Falls das Knotenstück nicht im Holzverband des Gurtes hergestellt, sondern als fertiges Erzeugnis in .den Gurt eingeführt wird, besteht die zusätzliche Schalung ausschließlich aus Schalungsbrettchen.If the knot is not made in the wooden bond of the belt, but as a finished product in .den belt is introduced, there is the additional Formwork exclusively from formwork boards.
Der in vorbeschriebener Weise hergestellte Formkasten wird mit plastischem Beton ausgefüllt, so da.ß nach Erhärtung des letzteren und nach Entfernung der Schalungsbrettchen ein aus Beton und Eisen bestehendes Knotenstück entstanden ist, in welchem die beiden Baustoffe gleicherweise wie im Knotenstück gemäß dem Hauptpatent infolge der Haftung einheitlich wirken und auch in derselben Weise die Gitterkräfte aufnehmen, wobei jedoch für den innexen Zusammenhang und für die Druckfestigkeit des Betons günstigere Verhältnisse auftreten, indem die die Zugkräfte der Gitterstäbe aufnehmenden Eisen Y den inneren Zusammenbang des Betons nicht b.eeintnächtigen und in Verbindung mit den Eisen w, w' eine Umschließung -des Betons bewirken.The molding box produced in the manner described above is made with plastic Filled with concrete, so that after the latter has hardened and after removing the formwork panels a piece of knot made of concrete and iron was created in which the two Construction materials in the same way as in the junction piece according to the main patent due to the liability act uniformly and also absorb the grid forces in the same way, with but more favorable for the internal context and for the compressive strength of the concrete Relationships occur by the iron absorbing the tensile forces of the bars Y do not interfere with the inner cohesion of the concrete and in connection with the iron w, w 'cause an enclosure of the concrete.
