Description
Profileisen fÜr bog e,4 eiege Streckenrahmen Die aus Profileisen, meistens Doppel-T-Eisen, bestehenden Rahmen Mir den Ausbau der Strecke in Bergwerksbetrieben werden durch in der Längsrichtung der Strecke verlaufende, aus Profileisen oder Rohren bestehende Bolzen abgestützt, die mit den Rahmen lösbar verbunden sind.Profile iron for bog e, 4 eiege stretch frames made of profile iron, mostly double T-irons, existing frames with the expansion of the line in mining operations are made of profile iron or extending in the longitudinal direction of the route Pipes supported existing bolts, which are releasably connected to the frame.
Zur Verbindung der Bolzen mit den Rahmen weisen letztere Aussparungen in ihrem Steg auf, während die Enden der Bolzen ausgeklinkt oder in anderer Weise bearbeitet werden, um das Einhängen in'die Rahmen zu ermöglichen.The latter have recesses to connect the bolts to the frame in their web while the ends of the bolts are notched or in some other way can be processed in order to enable them to be hooked into the frame.
Hierbei ist stets eine Bearbeitung der Rahnien sowohl als auch der Bolzen erforderlich, wodurch der Ausbau der Strecke wesentlich verteuert wird.Here is always a processing of the Rahnien as well as the Bolts required, which makes the expansion of the route much more expensive.
Es ist auch schon vorgeschlagen worden, die T-Eisen-Rahmen durch T-Eisen-Bolzen abzustützen, deren Steg an den Enden entsprechend dem Profil der Rahmen ausgeschnitten ist, so daß der Bolzen sich dicht gegen ' den Rahmen legen kann, wobei ein Kanten von Bolzen und. Rahmen durch die über die Flanschen des letzteren greifenden, beiderseits des Bolzens überstehenden Flanschenenden verhindert wird. Auch nach diesem Vorschlag ist eine Bearbeitung der Bolzen erforderlich, die erlieblich# Kosten verursacht, da Spiel an der Verbindungsstelle vermieden werden muß, wenn der Bolzen ohne weitere Verbindungsmittel gehalten werden soll. Eine einigerniaflen zuverlässige Verbolzung ist in dieser Weise ohne zusätzliche Befestigung nicht zu erreichen, da bekanntlich in Bergwerken dauernde Verschiebungen erfolgen. DerZweck derErfindung ist nun, alle diese Nachteile zu beseitigen, was dadurch erreicht wird, daß der Steg des kalimeneisens eingepreßte, warzenartige Vorsprünge auf-weist, über die im AusUati die Enden der rohr- oder rinnenförmigen Bolzen greifen.It has also been suggested that T-iron frame iron bolts T support by, the web is cut at the ends according to the profile of the frame, so that the bolt can lie tightly against 'the frame, wherein an edge of bolts and. Frame is prevented by the flange ends reaching over the flanges of the latter and protruding on both sides of the bolt. According to this proposal, too, machining of the bolts is required, which causes considerable costs, since play must be avoided at the connection point if the bolt is to be held without further connecting means. A somewhat reliable bolting cannot be achieved in this way without additional fastening, since, as is well known, permanent displacements occur in mines. The aim of the invention is now to eliminate all these disadvantages, which is achieved in that the web of the potash iron has pressed-in, boss-like projections over which the ends of the tubular or channel-shaped bolts grip in the AusUati.
In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel schematisch erläutert, wobei Fig. i einen senkrechten und Fig- 2 einen Waagerechten Profileisenquerschnitt darstellt.In the drawing, the invention is shown schematically in one embodiment explained, with Fig. 1 a vertical and Fig- 2 a horizontal profile iron cross-section represents.
In den Zeichnungen ist mit a ein doppel-T-förmiges Streckenbogeneiisen bezeichnet. Dieses Profileisen ist mit warzenförmigen Vorsprüngen b, c versehen, die zweckmäßig in den noch warmen Walzstab eingepreßt werden. Über diese Vorsprünge greifen im Ausbau die Enden der Bolzen.In the drawings, a denotes a double-T-shaped straight arc iron. This profile iron is provided with wart-shaped projections b, c , which are expediently pressed into the still warm roll bar. The ends of the bolts grip over these projections during expansion.
Es können je nach dem besonderen Verwendungsfall Einzelwarzen in beliebigen Ab- ständen oder wechselseitige Doppelwarzen eingepreßt werden, wie dies in den beiden Figuren dargestellt ist.It can stands in any absence or reciprocal double warts are pressed, as shown in the two figures, depending on the particular use case, individual warts.
