Abstract
Ein Rohrendverschluß ist als das Ende eines Rohres verschließende Kappe ausgebildet, die auf ihrer dem Rohrende zugewandten Seite mittels eines Gewindestiftes mit einem sich nach Einführen in das Rohr durch Expansionskraft an dessen Innenwand festsetzenden Preßkopf aus dünnwandigem Stahlblech verbunden ist.A pipe end closure is designed as a cap which closes the end of a pipe and is connected on its side facing the pipe end by means of a grub screw to a press head made of thin-walled steel sheet which is fixed on the inner wall after expansion into the pipe by expansion force.
Description
Der Gegenstand der vorliegenden Erfindung betrifft einen Rohrendverschluß. Hand läufe von Treppen oder Geländern werden beispielsweise aus Stahlrohr gefertigt. Derartige Konstruktionen weisen an den jeweiligen offenen Enden eine erhebliche Verletzungsgefahr auf. Daher ist es notwendig, die Enden zu verschließen. Das ge schieht entweder durch Anschweißen einer gewölbten Scheibe auf das Rohrende, wobei anschließend die Übergänge geschliffen werden müssen. Eine Alternative hierzu ist eine als Drehteil gearbeitete Vollhalbkugel mit Ansatz, die in das Rohr ein gesteckt wird. Hierbei ist nachteilig, daß aufgrund der Rohrtoleranzen kein fester Sitz gewährleistet ist.The object of the present invention relates to a pipe end closure. hand Stairways or railings are made of tubular steel, for example. Such constructions have a considerable amount at the respective open ends Risk of injury. It is therefore necessary to close the ends. The ge either by welding a curved washer onto the pipe end, after which the transitions must be ground. An alternative for this purpose is a full hemisphere made as a turned part with a shoulder that fits into the tube is stuck. The disadvantage here is that due to the pipe tolerances no fixed Seat is guaranteed.
Aufgabe der vorliegenden Erfindung ist es, einen Rohrendverschluß zu schaffen, der es ermöglicht, bei einfachster Montage am Rohr einen dauerhaften und festen Sitz zu gewährleisten.The object of the present invention is to provide a pipe end closure, which makes it possible to have a permanent and solid one with the simplest installation on the pipe Ensure fit.
Gelöst wird die gestellte Aufgabe durch die Merkmale des Anspruchs 1. Weitere Ausgestaltungen ergeben sich aus den Unteransprüchen 2 bis 7.The problem is solved by the features of claim 1. Further Refinements result from subclaims 2 to 7.
In der Zeichnung ist ein Ausführungsbeispiel des Gegenstands der Erfindung näher veranschaulicht. Es zeigen:In the drawing, an embodiment of the object of the invention is closer illustrated. Show it:
Fig. 1 einen erfindungsgemäßen Rohrendverschluß in der Seitenansicht, Fig. 1 is a Rohrendverschluß according to the invention in side view,
Fig. 2 bis 4 axiale Ansichten der Kappe, des Preßkopfes und des Rohrendes. Fig. 2 to 4 axial views of the cap, the press head and the pipe end.
Der Rohrendverschluß besteht aus einer Hohlhalbkugel 1, an deren inneren Ober fläche ein Ende eines Gewindestifts 2 bei 7 angeschweißt ist. An dem Gewindestift 2 ist vom anderen Ende her ein Preßkopf 3 befestigt. Der Preßkopf 3 wird durch Tiefziehen eines dünnwandigen Stahlblechs hergestellt und bildet einen topfförmi gen Hohlkörper. Im Inneren des zwischen zwei Muttern 5 an dem Gewindestift 2 befestigten Preßkopfes 3 ist eine Druck- bzw. Unterlegscheibe 4 angeordnet.The pipe end closure consists of a hollow hemisphere 1 , on the inner upper surface one end of a threaded pin 2 is welded at 7. A press head 3 is attached to the grub screw 2 from the other end. The press head 3 is made by deep drawing a thin-walled steel sheet and forms a topfförmi gene hollow body. A pressure or washer 4 is arranged inside the press head 3, which is fastened to the threaded pin 2 between two nuts 5 .
Der Rohrendverschluß wird mittels eines Kunststoffhammers in das Rohr 6 vom En de her eingetrieben. Der Preßkopf 3 liegt mit hohem Preßdruck an der Innenwand des Rohres 6 an, so daß eine Rückführung ohne Werkzeugeinsatz nicht möglich ist. Durch die Expansionskraft des Preßkopfes 3 werden Toleranzen im Rohrinnern aus geglichen, so daß stets ein fester Sitz im Rohr 6 gewährleistet ist, das ebenfalls aus Stahl besteht und bevorzugt als Handlauf dient.The pipe end closure is driven into the pipe 6 by means of a plastic hammer from the end. The press head 3 rests on the inner wall of the tube 6 with a high pressing pressure, so that a return is not possible without the use of tools. The expansion force of the press head 3 compensates for tolerances in the interior of the tube, so that a firm fit is always guaranteed in the tube 6 , which is also made of steel and preferably serves as a handrail.
Der mit dem Preßkopf 3 fest verbundene und durch die Druckscheibe 4 zusätzlich lagestabilisierte Gewindestift 2 ermöglicht der als Hohlhalbkugel ausgeführten Kap pe 1 einen versetzfreien Sitz am Ende des Rohres 6, der als zentraler Sitz für Hand läufe aus Stahlrohr von Bedeutung ist.The fixed to the press head 3 and in addition position stabilized by the pressure plate 4 threaded pin 2 enables the Cape configured as a hollow hemisphere pe 1 a versetzfreien seat at the end of the tube 6, which is as a central seat for handrails made of steel tube of importance.
