EINRICHTUNG ZUM HERSTELLEN VON BETONTEILEN.

摘要

The concrete components (11) are moulded, using a bottom support (18), pref. a central vibrator (17), a core (14) detachable from the mounting, a bottom ring (26) and a mould jacket (15). The jacket is first placed on the bottom ring above the core, with the two parts then lowered until the core protrudes inside them. Concrete is then delivered from the top into the mould chamber (16) and compacted, while the bottom ring and jacket continue to be lowered over the core until they reach the end position. A concrete filler (35) at the top mould jacket end is lowered simultaneously with the jacket and bottom ring so that concrete is always delivered to the top.
