Prestressing-rod insertion machine in concrete-component shuttering - arranges bars outside and lifts by manipulation into position in shuttering before screwing prestressing bolts on

摘要

The bars are produced on an endless track. They (3) are prearranged in a suitable mounting (6), from which they are lifted in batches by a manipulator (7) into the shuttering (1), where they are held by it in the exact position desired. A mechanism then screws the prestressing bolts in groups onto the threaded ends of the bars from outside the shuttering. The manipulator can be equipped to check automatically whether the bolts have been extracted before the bars are installed. ADVANTAGE - For prefabricated components such as beams. Entirely operated by machine, no manual labour being involved.
