Abstract

Pipe bend which is composed of two mating shells and has butt-straps which are arranged along the shell edges to be connected together, serve for the connection and reinforcement of the pipe bend, are connected to the two shells for this purpose and comprise interconnected webs, of the two shells, which are radially angled off outwardly and butt against one another over their surfaces, there being separated off, from the web (5) of one shell (1), a lug (7) which butts against the inner wall of the other shell (2). The invention is preferably used for waste-gas/supply-air guides in circulating-water heaters. <IMAGE>

Description

RohrbogenElbow

Die Erfindung betrifft-einen aus zwei gegengleich geformten Schalen zusammengesetzten Rohrbogen mit entlang der miteinander zu verbindenden Schalenränder angeordneten, der Verbindung und Versteifung des Rohrbogens dienenden und hierzu mit beiden Schalen verbundenen Laschen, die aus nach außen radial abge= winkelten, flächig aneinanderliegenden und miteinander verbun= denen Stegen der beiden Schalen bestehen. The invention relates to one of two oppositely shaped shells composite pipe bend with along the shell edges to be connected to each other arranged, the connection and stiffening of the pipe bend serving and this straps connected to both shells, which are angled radially outwards, webs of the two shells lying flat against one another and connected to one another exist.

Solche Laschen, die im Bereich der Längsverbindung der beiden Rohrbogen-Schalen verlaufend mit jeweils beiden Schalen verbunden sind, bewirken eine überaus wirksame Versteifung des von diesen Schalen gebildeten Rohrbogens und erfordern nur einen vergleichsweise geringen Mehraufwand an Material. Solche Laschen lassen sich außerdem ohne nennenswerten Aufwand mit den Schalen verbinden, so etwa durch Bördelung, Punktschweißung, durch Löten, Kleben, Nieten usw. Such brackets in the area of the longitudinal connection of the two pipe bend shells running connected to both shells, cause an extremely effective Stiffening of the pipe bend formed by these shells and require only one comparatively little additional expenditure on material. Such tabs can also be connect to the shells without significant effort, for example by flanging, spot welding, by soldering, gluing, riveting, etc.

Aufgabe der Erfindung ist es, einen solchen Rohrbogen der eingangs bezeichneten Gattung, dessen meist halbkreisförmig profilierte Hälften gemeinsam einen Kreisquerschnitt begrenzen, durch einfache konstruktive Maßnahmen formsteifer als bisher zu gestalten, so daß er aus vergleichsweise dünnem Blech doch ausreichend stabil gefertigt werden kann. Eine solche Form= steifigkeit des Rohrbogens erweist sich insbesondere dann als wünschenswert, wenn die Rohrbogen-Enden mit Schellen-gehalten werden müssen oder ein maßgenaue Ineinanderstecken von Rohr= schüssen und Rohrbogen geplant ist. The object of the invention is to provide such a pipe bend initially designated genus, whose halves, which are usually semicircular in shape, share limit a circular cross-section, more dimensionally stable through simple structural measures to be designed than before, so that it is still sufficient from comparatively thin sheet metal can be manufactured stably. Such a shape = stiffness of the pipe bend proves This is particularly desirable when the pipe bend ends are held in place with clamps must be or a dimensionally accurate interlocking of pipe sections and pipe bends it's planned.

Zur Lösung dieser Aufgabe ist vorgesehen, daß bei einem Rohrbogen der eingangs bezeichneten Gattung vom Steg der einen Schale ein Lappen abgetrennt ist, der sich an die Innenwandung der anderen Schale anlegt. To solve this problem it is provided that in a pipe bend of the genus mentioned at the beginning, a rag is separated from the web of one shell is, which rests against the inner wall of the other shell.

Die Anordnung und Einbindung dieses Lappens erbringt überraschenderweise eine wesentliche Erhöhung der Steifigkeit des Rohrbogens infolge einer besonders innigen Verbindung der einander zugewendeten Schalen-Randzonen. The arrangement and integration of this flap surprisingly yields a significant increase in the rigidity of the pipe bend as a result of a special intimate connection of the facing shell edge zones.

Zweckmäßigerweise sind die genannten Lappen in den beiden Endbereichen des Rohrbogens vorzusehen, also in Bereichen, wo an den Rohrbogen die benachbarten Schüsse von Rohrleitungen ansetzen und die radial abgewinkelten, nach außen ragenden Stege fehlen, um die Rohrschüsse auf die Enden des Rohrbogens aufschieben zu können. The lobes mentioned are expediently in the two end regions of the pipe bend, i.e. in areas where the adjacent pipe bends are attached to the pipe bend Apply sections of pipelines and the radially angled, outwardly protruding There are no webs so that the pipe sections can be pushed onto the ends of the pipe bend.

Die Anordnung der Lappen erweist sich als besonders wirksam, wenn sie mit der Wandung der gegenüberliegenden Schale fest verbunden, vorzugsweise verschweißt, sind. The arrangement of the lobes is found to be particularly effective when they are firmly connected to the wall of the opposite shell, preferably welded, are.

Ein Ausführungsbeispiel eines erfindungsgemäßen Rohrbogens ist nachstehend an Hand eines in den Zeichnungsfiguren ver anschaulichten Exemplares dargestellt und erläutert. Im einzelnen zeigt Fig.1 einen Querschnitt durch den Rohrbogen nach I-I der Fig.4, Fig.2 ein Detail im Längsschmitt nach II-II der Fig.l, Fig.3 den Ausschnitt III aus Fig.l in größerem Maßstab und Fig.4 die Seitenansicht des Rohrbogens mit Laschen nach Fig.3 und einer Ausbildung der Enden nach nach Fig.2. An embodiment of a pipe bend according to the invention is shown below shown on the basis of an exemplar illustrated in the drawing figures and explained. In detail, Fig.1 shows a cross section through the pipe bend I-I of FIG. 4, FIG. 2 a detail in the longitudinal Schmitt according to II-II of FIG. 1, FIG. 3 the Section III from Fig.l on a larger scale and Fig. 4 the side view of the pipe bend with tabs according to Figure 3 and a formation of the ends according to Figure 2.

Bei dem dargestellten Rohrbogen bestehen die Laschen aus nach außen in der Ebene 3 abgewinkelten, flächig aneinander= liegenden und miteinander verbundenen Stegen 4 und 5 der beiden Schalen 1 und 2, wobei die den Steg 6 bildende Lasche der Schale 2 die als einfacher Steg Q ausgebildete Lasche der anderen Schale 1 mit einem beidseits an diesem Steg 4 anliegenden Bördel 6 übergreift. Die Steifigkeit dieser Verbindung wird nun erfindungsgemäß noch zusätzlich dadurch erheblich vergrößert, daß die den einfachen Steg tP bildende Schale 1 außerhalb der Bördelverbindung den Rand der anderen Schale, an deren Innenwandung flächig anliegend mit einem Lappen 7 untergreift, der mit der Schale 2 durch Punktschweißung 8 verbunden ist. In the pipe bend shown, the tabs consist of the outside angled in level 3, flat against one another = lying and connected to one another Web 4 and 5 of the two shells 1 and 2, the tab forming the web 6 the shell 2, designed as a simple web Q, the flap of the other shell 1 with overlaps a flange 6 resting on both sides of this web 4. The rigidity this connection is now also considerably enlarged according to the invention that the shell 1 forming the simple web tP outside of the flanged connection Edge of the other bowl, lying flat against the inner wall with a rag 7 engages below, which is connected to the shell 2 by spot welding 8.
