Horst König, 1 Berlin 38, Wasgenstr. 18 Günter Halin, 1 Berlin 12, Witzlehenplatz 4 Zug- und/oder druckfeste Verbindung von Stäben Die Erfindung betrifft eine zug- und/oder druckfeste Verbindung von Stäben wie 3le beispielsweise in Stabtragwerken der Bautechnik an den sog. Knotenpunkten vorliegt.Hans-Hermann Böcker, 1 Berlin 31, Damaschkestr. 7 Dr.-Ing. Eckhard Reyer, 1 Berlin 47, Agnes-Straub-Weg 18 Ing.Horst König, 1 Berlin 38, Wasgenstr. 18 Günter Halin, 1 Berlin 12, Witzlehenplatz 4 Tensile and / or pressure-resistant connection of bars The invention relates to a tensile and / or pressure-resistant Connection of rods such as 3le, for example in structural engineering the so-called nodes is present.
Die Verbindung der Stäbe in den Knotenpunkten erfolgt bisher mit großem konstruktiven Aufwand, z.B. durch Schraubverbindungen und spezielle Knotenpunktbleche, durch Bchweißverbindungen zwischen an den Enden zusammengequetschten Rohren und Zylindersegmenten u.dgl. Man hat auch schon den Zusammenschluß der in einem Knotenpunkt zu verbindenden Stäbe mittels eines kugelförmigen Zwischenstückes, das eine entsprechonde Anzahl von Gewindebohrungen hat, deren Achsen in Richtung der auf ein anderstoßenden Gitterstäbe verlaufen, bewirkt, wobei jeder einzelne Gitterstab in die ihn zugeordnete Gewindebohrung geschraubt werden nuß.The connection of the rods in the nodes has so far been carried out with a large constructive effort, e.g. through screw connections and special junction plates, by welded joints between pipes and pipes that are squeezed together at the ends Cylinder segments and the like rods to be connected by means of a spherical intermediate piece, which has a corresponding Has number of threaded holes whose axes are in the direction of the abutting one another Lattice bars run, causing each individual lattice bar to be assigned to it Threaded hole to be screwed nut.
Den geschilderten Verbindungen haften neben dem Nachteil kostspieliger Fertigung verschiedene montagetechnische Schwierigkeiten an, z.. ist es nicht möglich, Montagespannungen auszuschließen; das gilt für statisch unbestimmte als auch für statisch bestimmte Systeme. In statisch bestimmten Systemen komnen die Montagespannungen durch die Abweichung ter Konstruktion von der Voraussetzung vollständig gelenkiger Knotenpunktverbindungen zustange.In addition to the disadvantage, the compounds described are more expensive Manufacturing various assembly-related difficulties, e.g. it is not possible to Exclude assembly stresses; this applies to statically indeterminate as well as to statically determined systems. The assembly stresses occur in statically determined systems completely articulated due to the deviation of the construction from the requirement Junction connections too.
Der Erfindung liegt die Aufgabe zu Grunde, daß die aufgezeigten Nachteile der herkömmlichen Konstruktionen vermieden werden. Die neue Verbindung ermöglicht eine sehr wirtschaftliche Herstellungstechnik und vermeidet die sonst üblichen montagebedingten Eigenspannungszustände.The invention is based on the object that the disadvantages indicated of conventional constructions can be avoided. The new connection enables a very economical production technique and avoids the usual assembly-related tasks Residual stress states.
Erfindungsgemäß wird dies dadurch erreicht, daß die Enden der zu verbindenden Stäbe in einem nit einen vergießoaren Medium ausgefüllten Gehäuse verankert sind, das seinerseits formgebend und/oder kraftübertragend wirkt.According to the invention this is achieved in that the ends of the to be connected Rods are anchored in a housing filled with a potted medium, that in turn gives shape and / or acts in a force-transmitting manner.
Die Herstellung dieser erfindungsgemäßen Verbindung erfolgt in einfacher Weise so, daß die Enden von Stäben durch entsprechende Öffnungen des Gehäuses, das beispielsweise als Hohlkugel mit einer der Anzahl der zu verbindenden Gitterstäbe entsprechenden Zahl von Öffnungen versehen ist, eingeschoben wird, woraufhin der verbleibende freie Raum innerhalb dieses Gehäuses über eine weitere Öffnung, die auch mit einem Anschlußstutzen versehen sein kann, mit einem Vergußmaterial ausgefüllt wird. Nach dem Erstarren des Vergußmaterials werden die funktionsbedingten Kräfte der Stäbe von demselben aufgenommen. Montagespannungen im Sinne von Nebenspannungen bei statisch bestimmten Stabtragwerken sowie Hontagespannungen bei statisch unbestimmten Stabtragwerken treten bei der erfindungsgemäßen Verbindung nicht auf, weil die Knotenpunktverbindung der Stäbe erst nach einer zwängungsfreien Aufstellung aller Tragglieder durch Ausgießen des Gehäuses erfolgt.This compound according to the invention is produced in a simple manner Way so that the ends of rods through corresponding openings of the housing, the for example as a hollow sphere with one of the number of bars to be connected corresponding number of openings is provided, is inserted, whereupon the remaining free space within this housing via another opening that can also be provided with a connecting piece, filled with a potting material will. After the potting material has solidified, the function-related forces of the rods taken up by the same. Assembly stresses in the sense of ancillary stresses with statically determined bar structures and honing stresses with statically indeterminate Bar structures do not occur in the connection according to the invention because the node connection of the bars only after a constraint-free installation of all support members by pouring of the housing takes place.
£11 gleicher Weise lassen sich auch die den von Seilen in Knotenpunkten anschließen.The lines of ropes in junctions can also be made in the same way connect.
Nach einem weiteren Erfindungsgedanken wird die Verankerung der Enden der Stäbe innerhalb des Gehäuses dadurch erreicht, daß diese Enden mit entsprechenden Ansätzen ausgerüstet sind.According to a further idea of the invention, the anchoring of the ends of the rods within the housing achieved in that these ends with corresponding Approaches are equipped.
als ausfüllende IIasse der Knotenelemente wird vorzugsweise ein erstarrendes Medium verwendet. llierfür kommen Spezialbetone, Kunststoffe, Mehrkomponentenkleber u.dgl. in Betracht.a solidifying one is preferably used as the filling-in of the node elements Medium used. There are special concretes, plastics and multi-component adhesives for them and the like.
Die Erfindung erlaubt jedoch grundsätzlich auch die Verwendung eines flüssigen oder gasförmigen ilediums für die Lraftübertragung swischen den zusammengefügten Enden von Stäben und dem Gehäuse. In einem solchen Falle wird,als weiterer Vorteil ein ständiger Längenausgleich innerhalb des so aufgebauten Stabtragwerkes erzielt, so daß jetzt beispielsweise Längenänderungen der Stäbe, wie sie durch Temperaturschwankungen auftreten können, automatisch kompensiert werden. Das Stabtragwerk bleibt jetzt stets frei von Sekundärspannungen.In principle, however, the invention also allows the use of a liquid or gaseous ilediums for the power transmission between the joined Ends of rods and the housing. In such a case, as a further advantage a constant length compensation is achieved within the bar structure constructed in this way, so that now, for example, changes in length of the rods as caused by temperature fluctuations can occur, are automatically compensated. The rod structure now remains always free of secondary stresses.
In der Zeichnung ist ein Busführungsbeispiel einer erfindungsgemäßen Verbindung schematisch dargestellt. Danach ragen die Enden der beiden Stäbe 1 und 2 in das als Hohlkugel ausgebildete Gehäuse 3 und sind in der dargestellten Lage durch das durch Punkte angedeutete vergießbare Medium 4 fixiert. Zur Verankerung der Stäbe 1 und 2 sind deren Enden mit den stegförmigen Ansätzen 5 und 6 ausgerüstet.The drawing shows an example of a bus routing according to the invention Connection shown schematically. Then protrude the ends of the two rods 1 and 2 into the housing 3, which is designed as a hollow sphere, and are in the position shown fixed by the castable medium 4 indicated by dots. For anchoring the ends of the rods 1 and 2 are equipped with the web-shaped projections 5 and 6.
