摘要： A method for the production of prestressed concrete products and a plant for implementing the method. Moulds provided with pretensioned wires are moved through fixed casting machines into a hardening space. In the hardening space, the combination of mould and product is lifted sideways from the casting line before hardening, using synchronised lifting equipment. The combination may be stacked for space economy. After hardening, the product is removed from the mould using the same lifting equipment. The moulds are returned to the beginning of the casting line, during which stage they are cleaned and refurbished. The products are transferred to cutting and finishing stations.

摘要： In the manufacture of prestressed concrete pipe, wire is wound under tension around the concrete body of the pipe and secured thereto. In accomplishing this the concrete pipe is mounted on a turntable for rotaton about the longitudinal axis of the pipe and wire under tension is wrapped thereon in a helical fashion from one end to the other.

摘要： A pocket former includes an outer barrel having a first rim, a second rim and a frustoconical body portion extending from the first rim to the second rim. A center barrel is connected to the outer barrel and has a proximal lip adjacent the first rim of the outer barrel, a distal lip adjacent the second rim of the outer barrel, and a tubular body portion extending from the proximal lip to the distal lip, and extends beyond both the first rim and the second rim. An annular flange curves out and away from the second rim of the outer barrel. A spiral surface is located on the frustoconical body portion of the outer barrel. A nut surface is located on the tubular body portion of the center barrel adjacent the distal lip.
