Abstract

Device for tensioning wire in the tensioned concrete construction, characterized by a housing provided for the support on one end of a concrete construction, in which a tensioning unit is mounted, from one end of which a traction member enters the housing axially movable, a coupling device for an anchor head of a wire bundle being mounted on the free end of the traction member, and at the same end centering means are provided for alignment of the traction member with the anchor head, as well as by means for holding the device temporarily for the construction of concrete, comprising the clamping means of tensioning elements, arranged on the outer face of the casing, whose tension force is adjustable, and the tensioning elements of the tensioning elements are provided of coupling organs, which make it possible to hold them in corresponding organs, together with the concrete construction (Machine-translation by Google Translate, not legally binding)
