Vorrichtullg znm Abdichten der zur aluminothermischen Verschweissung von Schienen,
Trägern u. dgl. dienenden Formen.
Bei der aluminothermischen Verschweissung von Schienen, Trägern u. dgl. werden die Schienen an der Stossstelle mit einer aus zwei Teilen bestehenden Form umgeben, deren Hohlraum mit Eisen und Schlacke in hocherhitztem, dünnflüssigem Zustand gefüllt wird. Damit die flüssige Masse weder durch die Fugen zwischen den Formteilen selbst, noch durch die Fugen zwischen Schienenoberfläche und Form entweichen kann, ist eine sichere Abdichtung dieser Fugen von grosser Bedeutung.
Die Abdichtung geschah bisher durch Aufschmieren eines geeigneten Stoffes, wie beispielsweise
EMI1.1
Die genannten Nachteile werden nach der Erfindung dadurch beseitigt, dass die Form mit Kanälen versehen wird, in welche die obengenannten Fugen einmünden, und dass in diese Kanäle vor der Schweissung ein plastisches Dichtungsmittel unter entsprechendem Druck eingespritzt wird. Hiebei füllen sich nicht nur die Kanäle, sondern auch die anstossenden Fugenteile mit dem Dichtungsmittel, so dass ein dichter Verschluss erzielt wird und die flüssige Masse nicht mehr auslaufen kann. Ferner wird das Dichtungsmittel durch die Wandungen der Kanäle festgehalten und kann d'iher durch den Druck

Device for sealing the aluminothermic welding of rails,
Carriers u. Like. Serving forms.
In the aluminothermic welding of rails, beams, etc. Like. The rails are surrounded at the joint with a two-part mold, the cavity of which is filled with iron and slag in a highly heated, low-viscosity state. So that the liquid mass can neither escape through the joints between the molded parts themselves nor through the joints between the surface of the rail and the mold, a reliable sealing of these joints is of great importance.
The sealing was done by smearing a suitable substance, such as
EMI1.1
The above-mentioned disadvantages are eliminated according to the invention in that the mold is provided with channels into which the above-mentioned joints open, and that a plastic sealing agent is injected into these channels under appropriate pressure before welding. In this case, not only the channels, but also the abutting parts of the joint fill with the sealant, so that a tight seal is achieved and the liquid mass can no longer run out. Furthermore, the sealant is held in place by the walls of the channels and can therefore be relieved by the pressure

much less time than the previous way of working.
