Description

Der Gegenstand der Erfindung ist eine Dichtungsanordnung für Anker-, Decken- und Stehbolzen, bei welcher behufs Dichtung der Gewindegänge das Bolzengewinde vom Innern des Bolzens aus; in radialer Richtung gegen das Muttergewinde gepreßt wird. Λ^οη bekannten derartigen Anordnungen unterscheidet sich die Dichtung gemäß der Erfindung dadurch, daß der Dichtungsdruck im Gewinde ίο mittels eines den Auftreibraum ausfütternden Stahlkerns aufrechterhalten wird,"der behufs Entspannung des Gewindedruckes in einen an den Auftreibraum sich anschließenden Auffangraum getrieben werden kann. Durch diese Anordnung wird eine auch gegen Erschütterungen und Temperaturschwankungen äußerst widerstandsfähige, dauerhafte Gewindedichtung erzielt, bei welcher im Bedarfsfalle behufs Lösung der Verbindung in einfacher Weise das Gewinde von dem durch den Stahlkern ausgeübten Druck entlastet zu. werden vermag.The object of the invention is a sealing arrangement for anchor bolts, ceiling bolts and stud bolts, in which, for the purpose of sealing the threads, the bolt thread from the inside of the bolt ; is pressed in the radial direction against the nut thread. According to known arrangements of this type, the seal according to the invention differs in that the sealing pressure in the thread is maintained by means of a steel core lining the expansion space, which can be driven into a collecting space adjoining the expansion space for the purpose of relieving the thread pressure Arrangement, a permanent thread seal that is extremely resistant to vibrations and temperature fluctuations is achieved, in which, if necessary, the thread can be relieved of the pressure exerted by the steel core in a simple manner in order to loosen the connection.

Die Zeichnung erläutert eine derartige Dichtungsanordnung.The drawing explains such a sealing arrangement.

Der Bolzen α ist an seinem Kopf mit einem leicht konischen Hohlraum b versehen, in welchen nach dem Einschrauben des Bolzens in das Muttergewinde c ein dem auszuübenden Dichtungsdruck entsprechend dickerer Stahlkern d getrieben wird, wobei der Hohlraum in bekannter Weise geweitet und das Bolzengewinde gegen das Muttergewinde gepreßt wird. Um diesen entsprechend gehärteten, im Hohlraum b verbleibenden und daThe bolt α is provided at its head with a slightly conical cavity b , into which, after the bolt has been screwed into the nut thread c, a steel core d corresponding to the sealing pressure to be exerted is driven, the cavity widening in a known manner and the bolt thread against the nut thread is pressed. To this correspondingly hardened, remaining in the cavity b and there

durch den vom Innern des Bolzens aus ausge- 35 übten Dichtungsdruck dauernd aufrechterhaltenden Stahlkern zu entfernen, ist an dem Hohlraum b ein der Größe des Stahlkerns entsprechender Auffangraum e angeschlosen, in welchen der Staihlkern, wenn der Bolzen aus 40 dem Muttergewinde ausgeschraubt werden soll, getrieben werden kann. Infolge der Lagenänderung des Stahlkerns vermag sich der bisher von diesem aufrechterhaltene Druck zwischen Bolzen- und Muttergewinde 45 zu entspannen, worauf der Bolzen aus seiner Verbindung verhältnismäßig leicht gelöst werden kann. Die erläuterte Dichtungsanordnung bietet noch den weiteren Vorteil, daß sie lediglich ein entsprechendes Ausbohren 50 der Bolzenenden erfordert und daher auch bei vorhandenen Bolzenverbindungen äußerst einfach zur Anwendung gebracht zu werden vermag.to be removed by the steel core, which is permanently maintained from the inside of the bolt, a collecting space e corresponding to the size of the steel core is connected to the cavity b , into which the steel core is driven when the bolt is to be unscrewed from the nut thread can be. As a result of the change in position of the steel core, the pressure previously maintained by this between the bolt and nut thread 45 is able to relax, whereupon the bolt can be released from its connection relatively easily. The sealing arrangement explained offers the further advantage that it only requires a corresponding drilling 50 of the bolt ends and can therefore be used extremely easily even with existing bolt connections.
