Abstract

A method of tensioning wires for use in the production of prestressed or post-tensioned concrete, which comprises anchoring the wires at one end, passing the wires at the other end of the mold, or in the beam or the like formed, each through a one-way gripping device, picking up food individually in a second one-way gripping device, said second one-way gripping device being intended to operate in the same direction as the first gripping device, moving the second one-way gripping device away from the first to tighten the wire by means intended to slip or register when the wire has been tightened by a predetermined amount, and then release the second one-way gripping device whereby the wire will be retained under the predetermined tension between the anchored limb and the first one-way gripping device.
