摘要

Cylinder head for anchoring concrete post-tensioning cables, of the kind comprising a support plate, from which a nozzle for the passage of the cables, reinforcing ribs between both and a helical armor around the nozzle, characterized essentially by the fact that the reinforcing ribs, of decreasing profile towards the nozzle, have in their edges transverse grooves, arranged so that they correspond to the turns of one end of the armature propeller, and the latter is mounted in the stock by friction adjustment in the helical guide formed by these notches.
