Description

Die Ausbaurahmen der Strecken unter Tage müssen gegen Umschieben gesichert sein. Zu diesem Zweck sind zweiteilige Abstandhalter im Einsatz, die jeweils bei zwei miteinander zu verbindenden Rahmen innenseitig die Profile umklammern, - wobei die Abstandlaschen der Umklammerung verschraubt oder vernietet sind. Diese Abstandhalter haben den Nachteil, daß sie zu stark abstandgebunden sind. Zum anderen gibt es Ausführungen, die nicht abstandgebunden sind. Hierbei sind die Abstandhalter durch Klemmkeile oder -schrauben verbunden. Die Klemmverbindungen haben den Nachteil, daß sie sehr stark von der Reibung, d. h. von der Anklemmung abhängig und somit immer mit einer gewissen Unsicherheit den Umschiebekräften unterworfen sind.The expansion frames for the underground routes must be secured against shifting be. Two-part spacers are used for this purpose, each at two frames to be connected to one another clasp the profiles on the inside, - whereby the spacer tabs of the clasp are screwed or riveted. These spacers have the disadvantage that they are too tightly spaced. On the other hand, there are versions that are not distance-bound. The spacers are by means of clamping wedges or screws connected. The clamp connections have the disadvantage that they are very strong from friction, d. H. depends on the connection and therefore always with one are subject to a certain degree of uncertainty.

Die Erfindung stellt durch eine Abscher-Abstandhalterverbindung der Haken einen absolut sicheren Verband der Ausbaurahmen her.The invention provides a shear spacer connection of the Hook an absolutely secure association of the expansion frame.

Gemäß einem Ausführungsbeispiel und an Hand einer Zeichnung nach Abb. I und II ist die Erfindung beschrieben und erläutert. Der Abstandhalter besteht aus zwei gleichförmigen, das Profil des Ausbaubogens halb umschließenden Haken i und ia. Die Arme der Haken sind auf der Ober-und Unterseite mit Nuten :2 in gleichmäßigem Abstand versehen. Auf den breiteren Rückenseiten der Arme, d. h. zur geschlossenen Seite des Hakens hin, sind ebenfalls in gleichmäßigem Abstand kugelförmige Vertiefungen 3 eingedrückt.According to an embodiment and on the basis of a drawing according to Fig. I and II the invention is described and explained. The spacer is made from two uniform hooks half-enclosing the profile of the extension arch i and ia. The arms of the hooks are on the top and bottom with grooves: 2 in evenly Provide spacing. On the wider back sides of the arms, i.e. H. to the closed Side of the hook, there are also spherical depressions evenly spaced 3 pressed in.

Zur Verbindung von zwei Rahmen wird der Haken i stoßseitig an einem Bogen und der Haken i. innenseitig an dem Nachbarbogen angelegt, so daß die Arme mit ihren Rückenseiten gegeneinanderliegen. Nunmehr wird ein U-förmiges Blech 5, in dessen Steg Warzen q. eingedrückt sind, über beide Arme geschoben, und zwar so, daß die Warzen in die kugelförmigen Vertiefungen 3 eingreifen. Die Flansche des U-Bleches 5 ragen etwas über die Arme heraus. Durch Aufsetzen und Zudrücken der Schließzange gemäß Abb. II werden die überstehenden Blechkanten des U-Bleches 5 an die Arme i und i" angedrückt und zu einer Hülse geschlossen. Gleichzeitig drücken die Schneiden 6 der Schließzange das U-Blech 5 in die Nuten 2 des Armes i" ein. Da die Hülse formschlüssig mit den beiden Armen verzahnt ist, kann sich die Verbindung nur durch Abscherung lösen und ist weitgehend zug- und druckfest. Da das Eindrücken der Hülse in die Nuten unabhängig von den Warzen. erfolgt, ist der Abstandhalter abstandunabhängig.To connect two frames, the hook i is attached to one Bow and hook i. on the inside of the neighboring arch so that the arms lie with their backs against each other. Now a U-shaped sheet 5, in the web of warts q. are pressed in, pushed over both arms, in such a way, that the warts engage in the spherical depressions 3. The flanges of the U-plates 5 protrude a little over the arms. By putting on and pressing the Locking pliers according to Fig. II are the protruding sheet metal edges of the U-plate 5 pressed against the arms i and i "and closed to form a sleeve. Press at the same time the cutting 6 of the locking pliers the U-plate 5 into the grooves 2 of the arm i ″. Since the sleeve is interlocked with the two arms, the connection can only loosen by shearing and is largely resistant to tension and compression. As the impression the sleeve into the grooves regardless of the warts. occurs, is the spacer independent of distance.
