Abstract

Die vorliegende Erfindung betrifft eine Vorrichtung zur Herstellung von langen, stabartigen, schlaffen oder vorgespannten Stahlbeton-Fertigteilen, bestehend aus einer Schalung mit Stahlhaut und einem diese abstützenden Skelett aus Stahlprofilen, an dem Außenrüttler zur Verdichtung des Betons installiert sind, wobei die gesamte Schalung auf schwingungsdämpfenden Elementen gelagert und ein starker Längsträger starr mit der Schalung verbunden ist. Aufgabe ist es, eine derartige Vorrichtung zur Verfügung zu stellen, die es gestattet, den Beton bei einer Lärmemission von ca. ≤ 90 dB (A) zu verdichten. Erfindungsgemäß wird diese Aufgabe mittels einer gattungsgemäßen Vorrichtung dadurch gelöst, daß an einer der Längsseiten des Längsträgers (12, 21) Pendelrüttler (13) mit horizontal ausgerichteten und zur Zwangssynchronisation miteinander gekoppelten Rotorwellen befestigt sind.

The present invention relates to a device for producing long, rod-like, flaccid or prestressed prefabricated reinforced concrete parts, consisting of a formwork with steel skin and a skeleton of steel profiles supporting this, on which external vibrators are installed to compress the concrete, the entire formwork being vibration-damping Elements stored and a strong side member is rigidly connected to the formwork. The task is to provide such a device that allows the concrete to be compacted with a noise emission of approx. ≤ 90 dB (A). According to the invention, this object is achieved by means of a generic device in that pendulum vibrators (13) are fastened to one of the long sides of the longitudinal beam (12, 21) with horizontally oriented rotor shafts coupled to one another for forced synchronization.
