Description
Die Erfindung betrifft einen wandernden Stützbogen für eine aus Einzelprofildielen gebildete, geschlossene, mit dem Stollen- bzw. Tunnelvortrieb wandernde Schutzhaube.The invention relates to a moving support arch for one made of single profile planks Formed, closed protective hood moving with the tunnel or tunnel drive.
,Es ist bereits eine Hilfseinrichtung zum Vortreiben der Einzelprofildielen mittels eines Hand-, hebels bekannt, die aus einem Blechkörper besteht, der an zwei aufeinanderfolgenden Lehrbögen leicht lösbar befestigt wird und Aussparungen als Widezlager für den Handhebel aufweist. ., It is already an auxiliary device for driving the single profile boards by means of a hand lever known, which consists of a sheet metal body, which is attached to two successive teaching sheets is easily detachably attached and recesses as Has Widezlager for the hand lever. .
Demgegenüber wird erfindungsgemäß vorgeschlagen, daß der wandernde Stützbogen die Stirnschalung für die herzustellende Tunnelwandung bildet und auf der Vorderseite einen Steg mit Rasten am Rand zum Ansetzen des Handhebels trägt. Hierdurch entfällt die lästige Arbeit des dauernden Befestigens, Lösens und Versrhi@ebene der oben beschriebenen Hilfseinrichtung. Gleichzeitig dient der Stützbogen auch als Schalung für den einzubringenden Beton des Tunnels bzw. Stollens.In contrast, the invention proposes that the wandering Support arch forms the front formwork for the tunnel wall to be produced and on the front has a bar with notches on the edge for attaching the hand lever. This eliminates the annoying work of constant fastening, loosening and versatility the auxiliary device described above. At the same time, the support arch also serves as formwork for the concrete to be introduced into the tunnel or gallery.
Eine Weiterausgestaltung der Erfindung besteht darin, daß der Stützbogen aus Flacheisen besteht, auf dessen Außenrand ein Rundeisen angeschweißt ist, das als Gleitbahn für die Einzelprofildielen dient.A further development of the invention is that the support arch consists of flat iron, on the outer edge of which a round iron is welded, the serves as a slide for the single profile boards.
Mit besonderem Vorteil ist schließlich noch der Steg zusätzlich durch Versteifungslaschen mit dem Flacheisen verbunden.Finally, the bridge is particularly advantageous Stiffening straps connected to the flat iron.
In der Zeichnung ist das Wesen der Erfindung beispielsweise und schematisch veranschaulicht, und zwar zeigt Fig. i die Vorderansicht des Stützbogens, Fig. ä die Innenansicht des Stützbogens und Fig. 3 den Querschnitt. des Stützbogens.In the drawing, the essence of the invention is exemplary and schematic Illustrates, namely Fig. i shows the front view of the support arch, Fig. Ä the interior view of the support arch and FIG. 3 the cross section. of the supporting arch.
Die wandernde Schutzhaube besteht aus Einzelprofildielen i, die von wandernden Stützbögen getragen werden. Die Dielen i sind mit Durchtrittsöffnungen 2 für einen Handhebel 7 versehen. Der Stützbogen besteht aus einem Flacheisen 3, das so zugeschnitten ist, daß es jeweils die Stirnschalung für die herzustellende Tunnelwandung io bildet. Auf seinem Außenrand ist ein Rundeisen 4 angeschweißt, während es auf der Vorderseite einen durchlaufenden Steg 5 mit Aussparungen 6 zum Einlegen eines Handhebels 7 aufweist. Außerdem ist der Steg 5' noch mit dem Flacheisen 3 durch Versteifungslaschen 8 verbunden. 9 ist die innere Schalwand für die herzustellende Betonwandung.The moving protective hood consists of single profile planks i, which are from wandering supporting arches. The boards i are with passage openings 2 for a hand lever 7 provided. The support arch consists of a flat iron 3, which is tailored so that it is the front formwork for the one to be produced Tunnel wall io forms. A round iron 4 is welded on its outer edge, while there is a continuous web 5 with recesses 6 on the front Has insertion of a hand lever 7. In addition, the web 5 'is still with the flat iron 3 connected by stiffening straps 8. 9 is the inner formwork wall for the one to be produced Concrete wall.
Wie insbesondere aus Fig. 3 ersichtlich ist, wird die Spitze des Handhebels 7 durch eine der Bohrungen 2 hindurchgesteckt und der Handhebel in eine entsprechende Aussparung 6 des Steges 5 eingelegt, worauf dann durch Drücken auf das Ende des Handhebels ein Verschieben der Einzeldielen erfolgt.As can be seen in particular from Fig. 3, the tip of the hand lever 7 inserted through one of the bores 2 and the hand lever in a corresponding one Recess 6 of the web 5 inserted, whereupon by pressing on the end of the The individual planks are shifted using the hand lever.
