ABSTRACT:
This invention relates to an apparatus for cutting away rivets of tensioned reinforcements which are protruding beyond the surface of a tension plate used for tensioning the reinforcements in order to increase the strength of a concrete product, characterized in that a chisel, for cutting rivets formed at the end of the tensioned reinforcements, is provided in such a manner that it can slide along the normal line of the tension plate and in contact with the surface of the tension plate, the chisel being interlocked with a fluid-pressure sliding mechanism, and further an immovable part of the mechanism is engaged with a part of the tension plate so that the counter force against the cutting by the chisel is obtained from the tension plate.
