Description

Grubenausbau aus inemanderge£ügtem,und an den Stoßstellen durch Muffen zusammengehaltenen i en Profileisensegmenten Die Erfindung bezweckt die Schaffung eines besonders formfesten eisernen Ausbaues für unter allseitigen .hohen Drucken stehende Bergwerksstrecken. Diese Aufgabe ist gemäß der Erfindung in der Weise gelöst, daß auf dem gesamten Umfang des Ausbaues die Segmente dreier doppel-T-förmiger Profileisenrahmen ineinandergefügt und die Segmente des mittleren Rahmens. etwa um eine halbe Längsteilung gegenüber denen der äußeren Rahmen versetzt sind. Ein derartiger Ausbau ist- sowohl in seiner Ebene wie quer dazu erheblich widerstandsfähiger als die bisher gebräuchlichen eisernen Ausbaugestelle, bei denen die aus einem einfachen Profileisen bestehenden Segmente entweder; sei es mit zwischengefügten Quetschkörpern oder ohne solche, stumpf aneinanderstoßen und durch Laschen miteinander vereint sind oder an ihren Enden ineinandergreifen oder bei dem ein aus einem einfachen Profileisenbogen bestehendes Ausbaugestell an seinen beiden Enden in aus zwei U-förmig gebogenen Profileisen gebildete Fußstücke oder bei kreisförmigem Ausbau in einen Ausbauunterteil eingreift, der aus zwei nebeneinanderhegenden Profileisenbogenstücken besteht, die in einem zur Aufnahme von verzugshölzern dienenden Abstand von zwei ebensolchen, aber mit ihnen nur durch zwei Schellenbänder vereinten Profileisenbogenstücken umgeben sind. Demgegenüber besteht das vorliegende Gestell auf seinem gesamten Umfang aus drei ineinandergefügten Profileisen, und diese sind außerdem noch rahmenweise um etwa eine halbe Längsteilung gegeneinander versetzt, so daß sie an den Stoßstellen einen sehr kräftigen Verband bilden. Der Ausbau kann in dieser Gestalt vollkommen starr oder auch mit Hilfe von an den Stoßstellen eingefügten Quetschkörpern bis zu einem gewissen Maß in Umfangsrichtung nachgiebig ausgebildet sein. Bei dem Türstockausbau hat man u. a. die Kappe schon aus drei ineinandergreifenden parallelen Schienen gebildet; hierbei sind jedoch die Schienenstücke in Längsrichtung nicht gegeneinander versetzt, und es ist auch nur die Türstockkappe derart verstärkt ausgebildet.Pit lining from one another, and at the joints through sleeves held together in profile iron segments. The aim of the invention is to create a particularly dimensionally stable iron extension for under high pressure on all sides standing mining lines. This object is achieved according to the invention in such a way that that on the entire scope of the expansion, the segments of three double-T-shaped profile iron frame nested and the segments of the middle frame. about half a lengthwise division compared to those of the outer frames are offset. Such an expansion is both Both in its plane and across it, it is considerably more resistant than the previously used ones iron support frames, in which the existing from a simple profile iron Segments either; be it with interposed squeezers or without them, butt against each other and are united by tabs or at their The ends interlock or the one consisting of a simple profile iron arch Extension frame at both ends in two U-shaped bent profile iron formed foot pieces or in the case of a circular extension engages in a lower extension part, which consists of two side-by-side profile iron arch pieces, which in one to accommodate warping wood serving spacing of two, but with they are surrounded only by two profile iron bow pieces combined. In contrast, the present frame consists of three over its entire circumference nested profile iron, and these are also still frame by about half a longitudinal division offset from one another, so that they have a form a very strong bandage. The expansion can be completely rigid in this form or with the help of crimps inserted at the joints up to one be designed to be resilient to a certain extent in the circumferential direction. With the door frame extension one has a. the cap already consists of three interlocking parallel rails educated; here, however, the rail pieces are not against each other in the longitudinal direction offset, and only the door frame cap is designed to be reinforced in this way.

Die Zeichnung veranschaulicht in den Abb. i und z einen gemäß der Erfindung ausgebildeten starren Ausbau in Seitenansicht und im Querschnitt nach A-B der Abb. i und in den Abb. 3 bis 5 einen in Umfangsrichtung nachgiebigen Ausbau in Seitenansicht und in zwei Querschnitten nach C-D und E-F der Abb.3 als Ausführungsbeispiele.The drawing illustrates in FIGS. I and z one according to FIG Invention trained rigid expansion in side view and in cross section according to A-B in Fig. I and in Figs. 3 to 5 a circumferentially flexible expansion in side view and in two cross-sections according to C-D and E-F of Figure 3 as exemplary embodiments.

Der Ausbau besteht aus drei oder auch noch mehr aufeinanderliegenden Rahmen, von denen jeder aus doppel-T-förmigen und an den Stoßstellen durch Muffen oder Schellenbänder b zusammengehaltenen Profileisensegmenten a gebildet ist. Der mittlere der Rahmen ist zwischen die Fuß- und Kopfflanschen der äußeren Rahmen eingefügt, und seine Segmente sind etwa um eine halbe Längsteilung gegenüber den Segmenten der äußeren Rahmen versetzt. Bei der -Ausführungsform nach Abb.3 bis 5 sind an den Stoßstellen der Rahmen Quetschkörper e zwischen den Segmentenden eingefügt.The expansion consists of three or more superimposed Frame, each of which is made of double-T-shaped and at the joints by sleeves or clamp bands b held together profile iron segments a is formed. Of the the middle frame is inserted between the foot and head flanges of the outer frame, and its segments are about half a pitch relative to the segments the outer frame is offset. In the embodiment according to Figures 3 to 5, the Joints of the frame squeeze body e inserted between the segment ends.
