Description
Grubenausbau Die Erfindung betrifft einen Grubenausbau, vornehmlich in Ring- oder Bogenform, aus ineinander verschieblichen belageisenartigen Profilen mit seitlichen Flanschen, an denen die Profile zusammenhaltende Klemmverbindungen angreifen.Pit lining The invention primarily relates to a pit lining in ring or arch form, made of sliding covering iron-like profiles with side flanges on which the profiles are held together by clamping connections attack.
Zur besseren Führung der Profile untereinander ist bereits vorgeschlagen worden, die Flansche auf der Ober- oder Unterseite mit einer Nut zu versehen und auf der jeweils gegenüberliegenden Seite eine Führungsleiste anzubringen, die bei ineinanderliegenden Profilen in die Nut eingreift. Diese bekannte Anordnung dient somit einem anderen Zweck als die Erfindung, der die Aufgabe zugrunde liegt, einen Grubenausbau der eingangs genannten Art so zu gestalten, daß größte Freiheit hinsichtlich der Wahl der Klemmverbindung besteht und deren Wirksamkeit erhöht werden kann. Zur Lösung dieser Aufgabe wird erfindungsgemäß vorgeschlagen, daß die Flansche auf der Ober- und Unterseite mit je einer Nut zur Aufnahme der an den Profilen anliegenden Teile der Klemmverbindungen versehen sind. Hierdurch werden die Klemmverbindungen nunmehr sowohl oben als auch unten in geeigneter Weise in den Nuten geführt und sind dadurch gegen Abrutschen bei einseitiger Anbringung gesichert. Vorteilhaft können die an sich bekannten Klemmvorrichtungen mit Schneiden in die Nuten eingreifen, so daß hierdurch eine zusätzliche Sicherung gegen Verschiebung oder Abrutschen entsteht.It has already been proposed to better guide the profiles with one another been to provide the flanges on the top or bottom with a groove and to attach a guide bar on the opposite side interlocking profiles engages in the groove. This known arrangement is used thus a different purpose than the invention on which the object is based, one To design pit expansion of the type mentioned so that the greatest freedom in terms of the choice of the clamp connection and its effectiveness can be increased. To the Solution to this problem is proposed according to the invention that the flanges on the The top and bottom each have a groove to accommodate those that are in contact with the profiles Parts of the clamp connections are provided. As a result, the clamp connections now both above and below in a suitable manner in the grooves and are thus secured against slipping when mounted on one side. Advantageous the known clamping devices with cutting edges can engage in the grooves, so that this creates an additional safeguard against shifting or slipping.
Weitere vorteilhafte Einzelheiten der Erfindung sind aus der Zeichnung ersichtlich, in welcher einige Ausführungsbeispiele erläutert sind. Es zeigt F i g. 1 einen Querschnitt durch die überlappungsstellung zweier Ausbauprofile nach der Erfindung, F i g. 2 einen Bogenausbau nach der Erfindung in Ansicht und einen Schnitt gemäß der Linie A-B in vergrößertem Maßstab und F i g. 3 eine andere Ausführungsform der Erfindung in einem Bogenausbau in Ansicht und einem Schnitt gemäß der Linie A-B.Further advantageous details of the invention are shown in the drawing can be seen in which some exemplary embodiments are explained. It shows F i G. 1 shows a cross section through the overlapping position of two expansion profiles of the invention, FIG. 2 an arch support according to the invention in view and a Section along the line A-B on an enlarged scale and FIG. 3 another embodiment of the invention in an arch extension in view and a section along the line AWAY.
Wie aus F i g. 1 ersichtlich, sind die erfindungsgemäßen neuen Rinnenprofile 1 an ihren seitlichen Gurtungen 2 an beiden gegenüberliegenden Seiten mit Nuten 3', 3" versehen.As shown in FIG. 1 shows the new channel profiles according to the invention 1 on their side straps 2 on both opposite sides with grooves 3 ', 3 "provided.
Nach der Darstellung der F i g. 2 greift in die Nuten einesProfils eineKlemmverbindung 4 kraftschlüssig an und ist dabei vor Kopf des Nachbarprofils angeordnet, so daß seine Klemmwirkung unabhängig von dem Zusammenhalt der beiden sich überlappenden Profile ist, welcher durch besondere in der Ansicht der F i g. 2 angedeutete Klemmen oder Führungen üblicher Bauart erreicht werden kann. Durch den Eingriff der Klemmen 4 in die Nuten der seitlichen Gurtungen wird die Führung der Klemmverbindung gesichert und die Gefahr eines Abrutschens beseitigt.According to the illustration of FIG. 2 engages in the grooves of a profile a clamp connection 4 and is in front of the head of the neighboring profile arranged so that its clamping effect is independent of the cohesion of the two overlapping profiles, which is characterized by special in the view of F i g. 2 indicated clamps or guides of conventional design can be achieved. By the engagement of the clamps 4 in the grooves of the side straps becomes the guide the clamp connection secured and the risk of slipping eliminated.
In dem Ausführungsbeispiel der F i g. 3 sind in gleicher Weise Klemmverbindungen 5 durch den Eingriff in die Nuten gesichert, welche die beiden Profile 1 und 1 in üblicher Weise gegeneinanderpressen und hierdurch den Einsinkwiderstand bestimmen. Die Klemmverbindungen können bei beidenAusführungsbeispielen mit Schneiden 6 versehen sein, mit welchen sie in die Nuten eingreifen und beim Anpressen in bekannter Weise den Klemmwiderstand durch Schneidwirkung bestimmen.In the embodiment of FIG. 3 are clamp connections in the same way 5 secured by engagement in the grooves which the two profiles 1 and 1 in Usually press against each other and thereby determine the resistance to sinking. The clamping connections can be provided with cutting edges 6 in both exemplary embodiments be, with which they engage in the grooves and when pressing in a known manner determine the clamping resistance by cutting action.
