Description

Muffenverbindung für ringförmigen -eisernen Grubenausbau Die vorliegende Erfindung betrifft eine Verbesserung `und weitere -Ausgestaltung einer Mufenverbindung nach Patent 613 042. Die Verbesserung bezieht-sich auf die Art und Weise der Verbindung der Endstücke der Ausbauglieder mit dem sie umschließenden Rohrstück im Wege der 1--,eilverspannungg. Es ist klar, daß die Keilverspannung eine festere ist, wenn an jeder. Stelle, .wo- ie_ Verkeilung stattfindet, statt .eines einzigen Keilstückes zwei oder mehrere Keile angebracht werden, die derart angeordnet werden, daß die Keilspitzen der nebeneinanderliegenden Keile jeweils 'abwechselnd in entgegengesetzte Richtungen zeigen. Um die gelenkartige Wirkung der Verbindungsstellen zu erzielen, werden die.Keilstücke teils aus einem festen Stoff (Eisen, Stahl o. dgl.), teils aus einem nachgiebigen Stoff (beispielsweise Holz) hergestellt, wobei jede Verbindungsstelle mindestens einnachgiebiges Keilstück aufweist.Socket connection for ring-shaped iron pit lining The present The invention relates to an improvement and further design of a socket connection according to patent 613 042. The improvement relates to the manner of connection the end pieces of the expansion members with the pipe section surrounding them by way of 1 -, fast tensioning. It is clear that the wedge bracing is tighter when at every. Place where wedging takes place instead of a single wedge two or more wedges are attached, which are arranged such that the Wedge tips of the adjacent wedges' alternate in opposite directions Show directions. In order to achieve the joint-like effect of the connection points, die.Keilteile are partly made of a solid material (iron, steel or the like), partly made of a pliable fabric (such as wood), with each joint has at least one resilient wedge.

Ein Ausführungsbeispiel ist in der Zeichnung dargestellt. In dieser ist der mit u bezeichnete Konstruktionsteil das in dem überzugsrohr liegende Endstück eines Bogenstückes, und der mit b bezeichnete Teil ist die Wand' des: -Überiugsrohres. -- Der -Keil c ist ein Keil aus festem Stoff, während die Keilstücke d und e' aus Holz oder sonstigem nachgiebigen Material bestehen. Der Vorteil einer derartigen Konstruktion liegt nicht nur in 'einer besseren -Keilverspannung, sondern auch darin, daßeine übergroße Beweglichkeit des -.Ringes in- seinen Gelenken vermieden wird. Das beschriebene Ausführungsbeispiel kann auch in der Weise abgeändert werden, daß entweder der Keile oder der Keil d in Fortfall gerät.An exemplary embodiment is shown in the drawing. In this the structural part marked u is the end piece located in the cover tube of an elbow, and the part marked b is the wall of the: -Überiugsrohres. - The wedge c is a wedge made of solid material, while the wedge pieces d and e 'are made of Consist of wood or other flexible material. The advantage of such Construction is not only about better wedge bracing, but also about that excessive mobility of the ring in its joints is avoided. The embodiment described can also be modified in such a way that either the wedge or the wedge d ceases to exist.

Claims (1)

PATENTANSPRUCH: Muffenverbindung für ringförmigen eisernen Grubenausbau nach Patent 613 042, dadurch gekennzeichnet, daß an den Keilflächen der in das Überzugsrohr hineingetriebenen Stahl- oder Eisenkeile, deren Keilspitzen in das überzugsrohr hineinzeigen, beiderseits oder einseitig Holzkeile anliegen, deren Keilspitzen in entgegengesetzter Richtung verlaufen. PATENT CLAIM: Socket connection for ring-shaped iron pit lining according to patent 613 042, characterized in that wooden wedges, the wedge tips of which run in the opposite direction, rest on both sides or on one side of the wedge surfaces of the steel or iron wedges driven into the cover pipe, the wedge tips of which point into the cover pipe.
