Description
Vorrichtung zur Herstellung von Betonpfählen mit verbreitertem Fuß Es sind Vorrichtungen zur I-Ierst-.llutilg von Betonpfählen mit verbreitertem Fuß aus einem Vortreibrohr und einem Rammkern bekannt, bei denen letzterer mit Kanälen versehen ist, die bei seinem Anheben dem Beton Durchtritt gewährt. - Nach der Erfindun- sind am unteren Ende des Rammkerns zwei etwa halbkreisförmige Schwingklappen angebracht, die beim Niederstampfen sich waagerecht stellen und dabei den lichten Querschnitt des Vortreibrohres ungefähr ausfüllen und die beimHochziehen des Rammkerns in senkrechte Stellung nach unten ausschwingen.Apparatus for the production of concrete piles with a widened foot There are devices for I-Ierst-.llutilg of concrete piles with a widened foot from a driving pipe and a ram core, in which the latter is provided with channels that allow the concrete to pass when it is lifted. - According to the invention, two semi-circular swing flaps are attached to the lower end of the ram core.
Im Vergleich zu ähnlichen bekannten Vorrichtungen ist der Rammkern vollkommen selbstwirkend. Er besteht aus äußert einfachen und widerstandsfähigen Einzelteilen die mit großer Sicherheit arbeiten und eine kräftige Stampfleistung ermöglichen. Beim Betonstampfen drückt der Beton die Schwingklappen so-fort aufwärts und die untere Rammkernfläche begrenzt dann selbst die Bewegung der Schwingklappen und hält sie in waagerechter Lage, in der sie gewissermaßen einen Kolben großer Fläche bilden. Sobald der Rammkern gehoben wird, schwingen die Klappen gegeneinander abwärts. Da sie durch den Ranunkern abgedeckt werden -, setzen sie dem Anheben desselben keinerlei Widerstände entgegen.Compared to similar known devices, the ram core completely self-acting. It consists of extremely simple and resilient Individual parts that work with great safety and a powerful tamping performance enable. When the concrete is tamped, the concrete immediately pushes the swing flaps upwards and the lower ram core surface then itself limits the movement of the swing flaps and holds it in a horizontal position, in which it is, so to speak, a piston large Form area. As soon as the ram core is lifted, the flaps swing against each other down. As they are covered by the ranunculus - they continue to raise it no resistance.
Die Erfindung ist beispielsweise auf der Zeichnung dargestellt: Die Abb.i und , zeigen je einen Längsschnitt, wobei die Schwinklappjen für eine Aufwärts- bzw. AI->i#"ärtsb#e-%7,7,egung des Kernes gezeigt werden.The invention is shown, for example, in the drawing: Fig.i and , each show a longitudinal section, the Schwinklappjen for an upward or AI-> i # "ärtsb # e-% 7.7, movement of the core are shown.
Abb.2 ist ein Querschnitt durch dit, Einrichtung, ES bezeichnen i das Vortreibrohr -, 2 den im Querschnitt kreuzförmigen Rammkern mit den Armen 3, die diesen an der Innenwandung des Rohres i führen. 5 sind die halbkreisförmigen Sch,#vingklappen, die schwenkbar auf einem Zapfcn4 befestigt sind. Es ist ersichtlich. daß der Beton a durch die Stampfwirkung des durch die waagerecht stehenden Klappen 5 gebildeten Kolbens verdichtet wird. Das Sinken des Betons zwisch-en dem Rohr i und den Armell 3 erfolgt selbsttätig, beim Anheben des Rammkerns.Fig.2 is a cross-section through dit, device, ES denote i the propulsion pipe -, 2 the cross-sectionally cross-shaped ram core with the arms 3, which guide it on the inner wall of the pipe i. 5 are the semicircular Sch, # vingklappen, which are pivotably mounted on a Zapfcn4. It can be seen. that the concrete a is compacted by the ramming action of the piston formed by the horizontally standing flaps 5. The sinking of the concrete between the pipe i and the armell 3 takes place automatically when the ram core is raised.
