Description

Verbindung .für zwei U-förmige, unmittelbar ineinandergleitende Ausbauteile nachgiebiger bogen oder jn,'iföirniger Grubenausbaurahmen Die Erfindung bezieht sich auf eine Verbindung für zwei U-förmige, unmittelbar ineinandergleitende Ausbauteile nachgiebiger bogen- oder ringförmiger Grubenausbaurahmen.Connection for two U-shaped extension parts that slide directly into one another yielding arched or jn, 'iföirniger pit support frame The invention relates relies on a connection for two U-shaped extension parts that slide directly into one another yielding arched or ring-shaped pit support frame.

Es sind unmittelbar in!einandergleitende, belageisenartig profilierte Ausbauteile bekannt, die durch in die Hauptgurtungen gelegte Verschraubungen aneinander befestigt sind. Zwischen beide Gurtungen können dabei Holzeinlagen ,eingeschaltet -,verden: Die gleichen Profile sind auch bereits mittels schellenartiger Vorrichtungen miteinander verbunden worden. Die Nachgiebigkeit dieser Verbindungen ist bis zu ihrer Endlage eine gleichmäßige; eine allmähliche Erhöhung des Widerstandes gegen den Gebirgsdruck kann mit diesen Verbindungen nicht erzielt werden. Es sind ferner Verbindungen bekannt, bei denen zwischen die zu verbindenden. Segmentenden U-förmige Einsatzstücke eingesetzt sind, die sich auf durch Schellen am Ausbau befestigten Holzkeilen verschieben und so eine Veränderung der Nachgiebigkeit auf Kosten des Holzes hervorrufen können. Diese Verbindungen sind jedoch teuer, unhandlich und infolge ihrer in den Streckenquerschnitt hineinragenden Keil- und Schellenteile unpraktisch für den Ausbau.They are profiled directly into one another, sliding in the manner of a covering iron Expansion parts known, which are attached to one another by means of screw connections placed in the main chords are attached. Wooden inlays can be switched between the two straps -, verden: The same profiles are already in place by means of clamp-like devices have been connected to each other. The compliance of these connections is up to their end position a uniform; a gradual increase in resistance to the rock pressure cannot be achieved with these connections. There are also Connections known where between the to be connected. Segment ends U-shaped Inserts are used, which are attached to the expansion by clamps Shifting wooden wedges and thus changing the flexibility at the expense of the Can cause wood. However, these connections are expensive, cumbersome and due to their wedge and clamp parts protruding into the cross-section of the route impractical for expansion.

Die Erfindung vermeidet diese Nachteile. Die Verwendung von besonderen Laschen für die nachgiebige Verbindung der beiden Aushauteile fällt fort. Zwei U-förmige Ausbauteile gleiten unmittelbar ineinander, indem der um die Flanschen gebogene, im Querschnitt größere Ausbauteil an der Innenseite der Flanschen nach der Mitte des Ausbauteils hin ansteigende schiefe Ebenen aufweist, auf die sich die Flanschen des ün Querschnitt kleineren Ausbauteils aufschieben. Eine einfache Verbindung mittels Schrauben oder klammerartiger Vorrichtungen genügt, um ein seitliches Verschieben der ineinandergleitenden Profile zu verhindern.The invention avoids these disadvantages. The use of special Lugs for the flexible connection of the two skin parts are omitted. Two U-shaped Removal parts slide directly into one another, as the A larger cross-section on the inside of the flanges towards the middle of the extension part has sloping planes that rise up onto which the flanges are located Slide on the expansion part with the smaller cross-section. A simple connection using Screws or clamp-like devices are sufficient to move them sideways to prevent profiles sliding into one another.

Durch die Erfindung wird eine einfache, leicht zu handhabende Verbindung der Segmente geschaffen. Durch den Fortfall jeglicher zusätzlicher Teile ist die Verbindung billig und vermeidet gefahrbringende, in den Streckenquerschnitt vorstehende Teile. Auch wird durch diese Verbindung infolge der Schrägflächen die Nachgiebigkeit des Ausbaues bis zu hohen Gebirgsdrücken aufrechterhalten und der Größe des Gebirgsdruckes angepaßt.The invention provides a simple, easy-to-use connection of the segments created. By eliminating any additional parts, the Connection cheap and avoids dangerous, protruding in the cross-section of the route Parts. This connection also increases the flexibility due to the inclined surfaces of expansion up to high mountain pressures and the size of the mountain pressure customized.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgedankens dargestellt, und zwar zeigt Abb. i einen Schnitt durch die Verbindung nach Linie I-I der Abb. 2, die eine Ansicht der Verbindung zweier U-förmiger Profile darstellt.In the drawing is an embodiment of the inventive concept shown, namely Fig. i shows a section through the connection by line I-I of Fig. 2, which is a view of the connection of two U-shaped profiles.

i ist das äußere U-förmige Ausbauprofil, in dem das ebenfalls U-förmige Ausbauprofil e gleitet, wobei die beiden Profile in bekannter Weise durch Bolzen 3 in Langlöchern 4 miteinander verbunden sind. Das innere Profil 2 gleitet an seinem Ende mit seinen Flanschen auf den schiefen Ebenen 5 des Profils i, die das Zusammenschieben der beiden Profile erschweren, indem dem Gebirgsdruck ein ansteigender Gegendruck entgegengesetzt wird. Bei dieser Verbindung evtl. um die Profile greifende Klammern, die an Stelle der Schrauben eine seitliche Verschiebung der ineinandergleitenden Profile gegeneinander verhindern, sind in der Zeichnung nicht dargestellt.i is the outer U-shaped extension profile in which the U-shaped Extension profile e slides, the two profiles in a known manner by bolts 3 are connected to one another in elongated holes 4. The inner profile 2 slides on his End with its flanges on the inclined planes 5 of the profile i, which are pushing together of the two profiles make it more difficult by the rock pressure an increasing counterpressure is opposed. With this connection, brackets possibly reaching around the profiles, instead of the screws, a lateral displacement of the interlocking ones Prevent profiles against each other are not shown in the drawing.
