Method for production of shuttering tie rod and shuttering tie rod

摘要

A method for production of a formwork tie rod is described, characterized in that on a homogeneous core (1) in a form of a threaded rod, in the middle portion thereof, a longitudinal conical sheath (2) having a circular cross-section, made of a readily workable material selected from a group consisting of metals, metal alloys and plastics, is permanently and concentrically fixed, and either the sheath (2) is entirely made of metal or entirely made of plastic; or the sheath (2) is made of metal conical ending sleeves - the more narrow one (2C) and the more wide one (2D) - and made of plastic that is filling a space between these two ending sleeves.
