Description

Gußform zur Herstellung von Eisenbahnschwellen aus Eisenbeton. Es ist bereits bekannt, Eisenbahnschwellen u. dgl. aus Eisenbeton durch Gießen in Formen herzustellen, in denen vorher auf Schraubenbolzen angebrachte Eisenspiralen angeordnet werden, wobei die Schraubenbolzen die Gußkerne zur Herstellung der Löcher für die entsprechenden S.ehienenbefestigungsbolzen bilden. Bei Eisenbahnschwellen ändert sich nun die Spurweite, je nachdem, ob es sich um eine geradlinige oder kurvenförmige Strecke handelt und je nach den verschiedenen Krümmungsradien der Kurve. Bisher finden zur Herstellung der Eisenbahnschwellen mit verschiedener Spurweite immer der Spurweite entsprechende Formen Anwendung, so daß eine sehr große Zahl solcher Formen notwendig ist.Casting mold for the production of railway sleepers from reinforced concrete. It is already known to make railway sleepers and the like made of reinforced concrete by pouring them into molds produce, in which previously attached iron spirals on screw bolts arranged be, the screw bolts are the cast cores for making the holes for the Form corresponding rail fastening bolts. Changes in the case of railway sleepers the track width, depending on whether it is straight or curved Route acts and depending on the different radii of curvature of the curve. Until now always find for the production of the railway sleepers with different gauges Forms corresponding to the gauge are used, so that a very large number of such Molding is necessary.

Gemäß der Erfindung findet zum Gießen der Eisenbahnschwellen eine einstellbare Form Anwendung, die es ermöglicht, Eisenbahnschwellen mit verschiedener Spurweite herzustellen. Das Wesen der Erfindung liegt darin, daß in der- Form ein Teil vorgesehen wird, dessen Lage in der Längsrichtung der Schwelle einstellbar ist und der die Öffnungen aufweist, die zur Aufnahme der Köpfe der Schraubenbolzen bestimmt sind, welche die Gußkerne bilden.According to the invention, one finds for casting the railway sleepers adjustable shape application that allows railway sleepers with different Establish track gauge. The essence of the invention is that in the form of a Part is provided, the position of which is adjustable in the longitudinal direction of the threshold and which has the openings for receiving the heads of the screw bolts are determined which form the casting cores.

Der Erfindungsgegenstand ist beispielsweise in einer Ausführungsforen in der Zeichnung dargestellt, und zwar zeigt: Abb. i eine Schienenbefestigung, Abb.2 eine Einrichtung zum Gießen der Schwelle, Abb.3 einen Querschnitt durch eine Gußform zur Herstellung von Schwellen mit verschiedener Spurweite, Abb. 4 eine teilweise Aufsicht auf die Einrichtung zum Verändern der Spurweite, Abb. 5 eine Seitenansicht zu Abb.4. Abb.6 ein spiralförmiges Flacheisen für die Schraubenbolzen.The subject matter of the invention is, for example, in an execution forum shown in the drawing, namely: Fig. i a rail fastening, Fig.2 a device for casting the sleeper, Fig.3 a cross-section through a casting mold for the production of sleepers with different gauges, Fig. 4 a partial Top view of the device for changing the track width, Fig. 5 is a side view to Fig.4. Fig.6 a spiral flat iron for the screw bolts.

Zur Erläuterung der. Erfindung sind in den Abb. i und 2 in bekannter Ausführung die Befestigung einer Schiene auf einer Schwelle und eine Einrichtung zum Gießen der Schwelle dargestellt. Die Schiene i ist unter Vermittlung der Platten 2 und 3 durch mit spiralförmigen Flacheisen 6 versehene Schraubenbolzen 5 mit der Schwelle 4 verbunden. Zum Gießen der Betonschwelle werden in die Öffnungen 8, 8' des Bodens 7 der Gußform die in der Unterlagsplatte sitzenden und mit spiralförmigen Flacheisen versehenen Schraubenbolzen eingesetzt. Nach Anbringen der Eisenausrüstung i o wird dann die Masse i i in die Form gegossen.To explain the. Invention are in Figs. I and 2 in known Execution of fastening a rail on a sleeper and a facility shown for casting the sleeper. The rail i is mediated by the panels 2 and 3 by provided with spiral flat iron 6 screw bolts 5 with the Threshold 4 connected. To pour the concrete sleeper, openings 8, 8 ' of the bottom 7 of the mold, the seated in the base plate and with spiral-shaped Flat iron studs are used. After attaching the iron equipment i o the mass i i is then poured into the mold.

Bei der gemäß der Erfindung ausgebildeten Gußform wird in einem entsprechenden Ausschnitt des Bodenbrettes 12 ein verschiebbar gelagerter Holzblock 14 angebracht, der entsprechende Öffnungen zum Einsetzen der Köpfe der Schraubenbolzen und der Unterla.gsplatte aufweist. Der Holzblock 1 ¢ ist durch Eisenplatten 15, 15' verstärkt und in den Führungswinkeln 16, 16', 16", 16"' verstellbar gelagert. Zu seiner Einstellung sind Handgriffe 17 und 17' vorgesehen. Auf den Winkeln 16, 16"' sind mit der Form fest ver-.bundene Binder 13, 13' gelagert, die, wie der Holzblock 1 ¢ und die Winkel 16, 16"', mit Löchern zum Einsetzen von Stiften i g, i g' versehen sind. Die Entfernung zwischen zwei Löchern des Holzblockes 14 ist kleiner als die Entfernung der Löcher der Binder 13 und 13', und zwar beispielsweise um 2 mm. Die Einrichtung kann dabei so getroffen sein, daß, wenn der Stift i g durch das erste Paar Löcher hindurchgeht, die normale Spurweite eingestellt wird, während man mit einem andern Lochpaar eine Spurweite einstellt, die einen Unterschied mit der ersten um beispielsweise 2, 4, 6 mm usw. aufweist. Für die Verstellung des Holzblockes 14 muß der im Bodenbrett 12 der Form geschaffene Ausschnitt um etwa 2 cm größer sein als die Länge des Holzblockes 14.In the mold formed according to the invention is in a corresponding Cutout of the floor board 12 a slidably mounted block of wood 14 attached, the corresponding openings for inserting the heads of the screw bolts and the Has Unterla.gsplatte. The wood block 1 ¢ is reinforced by iron plates 15, 15 ' and adjustable in the guide brackets 16, 16 ', 16 ", 16"'. About his attitude handles 17 and 17 'are provided. On the angles 16, 16 "'are with the shape Firmly connected binders 13, 13 'mounted, which, like the block of wood 1 ¢ and the angle 16, 16 "', are provided with holes for inserting pins i g, i g'. The removal between two holes of the wooden block 14 is smaller than the distance of the holes the binder 13 and 13 ', for example by 2 mm. The facility can do this be made so that when the pin i g passes through the first pair of holes, the normal track width is set, while one with another pair of holes one Sets the track width that differs from the first one by, for example, 2, 4, 6 mm, etc. For the adjustment of the wooden block 14 must be in the floor board 12 cut out of the shape should be about 2 cm larger than the length of the wood block 14th
