KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Vorliegende Erfindung betrifft eine Vorrichtung zum Stampfen hohler Gegenstände aus Beton o. dgl., welche im Wesen darin besteht, daß der Kern beim Stampfen nicht, wie bisher, fest steht, sondern mit dem Stampfer zusammenhängt und mit diesem gehoben und fallen gelassen oder niedergedrückt wird. Dadurch wird ein Anhaften des Betons an den Kern vermieden und außerdem das besondereThe present invention relates to a device for tamping hollow objects made of concrete or the like, which essentially consists in the fact that the core does not as before, is fixed, but is related to the tamper and lifted and with this dropped or depressed. This prevents the concrete from sticking to the Core avoided and also the special
ίο Herausheben des Kernes erspart, indem dieser mit dem Stampfer zusammen hochgehoben wird, so daß die fertige Form sofort entfernt werden kann. Es sind zwar Preßvorrichtungen zur Herstellung von Röhren bekannt, bei denen auch der Kern zugleich mit der Preßfläche aus dem Hohlkörper entfernt wird. Diese bekannten Vorrichtungen betreffen jedoch keine Stampfer, und es können mit denselben nur Rohre mit kreisförmigem Querschnitt hergestellt werden, während die Stampfvorrichtung nach vorliegender Erfindung sich zur Herstellung von Hohlkörpern von beliebigem Querschnitt eignet.ίο saving the core by removing this is lifted together with the tamper, so that the finished form is removed immediately can be. There are known pressing devices for the production of tubes, in which the core is removed from the hollow body at the same time as the pressing surface. However, these known devices do not relate to rammers and can do with the same only pipes of circular cross-section can be made while the ramming device according to the present invention is suitable for the production of hollow bodies of any cross-section.
In der Zeichnung ist eine beispielsweise Ausführungsform der Vorrichtung dargestellt. An example embodiment of the device is shown in the drawing.
Die Form α wird auf einem Tisch b be- ■ festigt, in welchem der Kern c in einem Ausschnitt geführt wird. Der Kern c trägt zugleich die Stampffläche d und ist mit einer Zahnstange e verbunden, mittels welcher der Kern durch ein entsprechendes Getriebe gehoben und auf das in der Form befindliche Material/ fallen gelassen oder niedergedrückt wird.The shape α is fastened on a table b in which the core c is guided in a cutout. The core c at the same time supports the tamping surface d and is connected to a toothed rack e , by means of which the core is lifted by a corresponding gear mechanism and dropped or pressed onto the material / in the mold.
Während des Stampfens wird bei hochgehobenem Stampfer stets ein wenig frisches Material nachgefüllt, bis das Formstück fertig ist, worauf der Kern aus der Form gehoben und die Form entfernt werden kann.During the pounding process, there is always a little fresh when the pounder is raised Material refilled until the molding is finished, whereupon the core comes out of the mold lifted and the mold can be removed.
