Description
Verbindung zweier sich außermittig kreuzender und über den Kreuzungspunkt durchlaufender Rohre, Rundstäbe od. dgl.Connection of two eccentrically crossing and over the crossing point continuous pipes, rods or the like.
durch Schweißverbindung Für Rohre, welche sich in einer Ebene oder außermittig kreuzen und somit über den Kreuzungspunkt durchlaufen, sind feste und lösbare Verbindungen verschiedener Art bekannt. Bei Stahlrohrgerüsten hat man schon lösbare Verbindungen für rechtwinkelig, in geringem Abstand voneinander, sich kreuzende Rohre benutzt, die in Form von Schellen ausgeführt sind. Auch hat man sich kreuzende Rohre oder Stangen durch Schweißung miteinander verbunden. Eine solche Verbindung ist für viele Zwecke ausreichend, dagegen dort unzureichend, wo auf die Verbindungsstelle starke Kräfte einwirken, insbesondere auch solche, welche die verbundenen Rohre oder Stangen gegeneinander zu verdrehen suchen.through welded connection For pipes, which are in a plane or Crossing off-center and thus passing through the crossing point are fixed and detachable connections of various types are known. With tubular steel scaffolding you already have Detachable connections for right-angled, at a short distance from each other, intersecting Pipes used, which are made in the form of clamps. You also have intersecting Pipes or rods connected to one another by welding. Such a connection is sufficient for many purposes, but insufficient where the connection point strong forces act, especially those affecting the connected pipes or trying to twist rods against each other.
Bei Rohren, die winkelig zueinander in einer Ebene verlaufen, sind schon laschenförmige Knotenbleche verwendet worden. welche in Anpassung, an die jeweiligen Winkel, in denen sich die Rohre treffen, ausgeschnitten, an die Rohre, diese teilweise überdeckend, angelegt und mit den Rohren verschweißt werden.For pipes that run at an angle to each other in one plane, are strap-shaped gusset plates have already been used. which in adaptation to the respective angles at which the pipes meet, cut out, on the pipes, this partially overlapping, created and welded to the pipes.
Bei Verbindungen sich kreuzender Rohre sind auch schon Paßstücke bekannt, die eine Aussparung für das eine einzuschweißende Rohr aufweisen, wogegen die anderen Rohre stumpf an das Paßstück angeschweißt sind.Fitting pieces are already known for connections between intersecting pipes, which have a recess for the one pipe to be welded, while the other Pipes are butt welded to the fitting piece.
Bei einer anderen Ausführung werden sich kreuzende Vierkantstäbe oder Rohre in ihrer Winkelstellung nur durch kreuzförmige Paßstücke mit seitlichen Laschen an den Armen, die um die Rohre gebogen werden, zusammengehalten und in dieser Stellung in primitiver Form durch eine Klammer gesichert.In another design, square bars or intersecting Pipes in their angular position only by means of cross-shaped adapters with side tabs held together by the arms that are bent around the tubes and in this position secured in primitive form by a bracket.
Diese bisher benutzten Formen fester Verbindungen haben den Mangel entweder durch die Art ihrer Ausführung den gebildeten Knotenpunkt zu schwächen oder für die Herstellung eines solchen Knotenpunkts eine jeweils anzupassende, fertigungstechnisch aufwendige Ausführung erforderlich zu machen.These previously used forms of fixed connections are deficient either by the way they are carried out to weaken the node that has been formed or for the production of such a node, one that has to be adapted in terms of production technology to make complex execution necessary.
Die Erfindung vermeidet diese Mängel für die Verbindung sich kreuzender Rohre durch die Verwendung eines als prismenstumpfförmiger Kasten ausgebild#ten Knotenstückes, das vier gleiche oder zwei Paare gleichartiger, mit Aussparungen für die Rohre versehene Wände aufweist, wobei die in die entsprechenden Aussparungen eingelegten Rohre mit diesen verschweißt sind. Dadurch, daß die in beiden Aussparungen des Knotenstückes eingelegten Rohre od. dgl. durch Verschweißung an zwei Längsnähten und zwei Durchmessernähten in einer sehr haltbaren und stabilen Form miteinander verbunden sind, bietet diese Anordnung besonders auch gegenüber Ver-C drehungen der beiden Rohre und anderen derartigen Kräften völlige Sicherheit.The invention avoids these shortcomings for the connection of intersecting ones Pipes through the use of a box designed as a truncated prismatic box Knot piece, the same four or two pairs of the same type, with recesses for the tubes provided walls, which in the corresponding recesses inserted pipes are welded to these. Because the in both recesses of the junction piece inserted pipes or the like by welding at two longitudinal seams and two diameter seams in a very durable and stable form with each other are connected, this arrangement offers especially against twisting the two pipes and other such forces complete security.
Weitere Merkmale der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispieles.Further features of the invention emerge from the following Description of an embodiment.
Fig. 1 zeigt zwei sich rechtwinklig kreuzende Rohre 1 und 2, die durch das Knotenstück 3 gemäß der Erfindung verbunden sind. Fig. 2 und 3 zeigen weitere Ansichten der Verbindung. In Fig. 4 ist das Knotenstück im Schaubild gezeigt. Es hat vier Wände 3, 4, 5 und 6, von denen die Wände 3 und 5 mit halbrunden Ausnehmungen zum Einlegen des Rohres 2 und die Wände 3 und 6 mit halbrunden Ausnehmungen zum Einlegen des Rohres 1 versehen sind. Wie die Zeichnung erkennen läßt, sind die Berührungslinien zwischen dem Knotenstück und den beiden Rohren verhältnismäßig lang, wodurch eine einfache und sehr haltbare Schweißverbindung erreichbar ist.Fig. 1 shows two tubes 1 and 2 crossing at right angles, which are connected by the junction piece 3 according to the invention. Figures 2 and 3 show further views of the connection. In Fig. 4 the node is shown in the diagram. It has four walls 3, 4, 5 and 6, of which the walls 3 and 5 are provided with semicircular recesses for inserting the tube 2 and the walls 3 and 6 with semicircular recesses for inserting the tube 1 . As the drawing shows, the lines of contact between the junction piece and the two tubes are relatively long, so that a simple and very durable welded connection can be achieved.
Das Knotenstück nach Fig. 4 hat die Gestalt eines offenen Rahmens mit vier Wänden. Es liegt im Bereich derErfindung, das Knotenstück alsVollkörper mit halbzylindrischen Ausnehmungen herzustellen. Für Rohre oder Stangen mit anderen Querschnitten können die Knotenstücke entsprechend geformt sein. Auch ist es möglich, Rohre oder Stangen mit unterschiedlichen Durchmessern miteinander zu verbinden, wobei auch der Kreuzungswinkel größer oder kleiner als 90' sein kann.The node of Fig. 4 has the shape of an open frame with four walls. It is within the scope of the invention to produce the node piece as a solid body with semi-cylindrical recesses. The junction pieces can be shaped accordingly for tubes or rods with other cross-sections. It is also possible to connect tubes or rods with different diameters to one another, whereby the crossing angle can also be larger or smaller than 90 '.
