    摘要： A method and system are described for tensioning structural strands 1 of a tendon in a duct. Each strand 1 is fitted with its own load cell 22, so that the individual tension values in each individual strand 1 can be measured during the tensioning of the strands 1. The load cells 22 may be removed after tensioning, or left in situ to enable ongoing monitoring of the tension in the strands 1. The load cells 22 may be calibrated simultaneously by tensioning the strands 1 to an equal tension using individual jacks 10, then normalizing the signals from each load cell 22 to the known equal tension value. A further calibration to a global strand load measurement may also be performed.

    摘要： A pocket former includes a pocket former body and a keyway former. The pocket former is adapted to form a void in a concrete member allowing access to the stressing end of a post-tensioning tendon. The keyway former is adapted to form a keyway in the concrete to allow grout to be more securely retained in the void.

    摘要： A device and a method for controlling a clamping press is provided when clamping a tension member as a function of the clamping force of a reference clamping member. The device has a hollow, cylindrical housing, wherein a piston coupled to the reference tension member is supported longitudinally displaceably along an axis. The housing and the piston encompass a pressure chamber that can be acted upon by a pressure medium for performing an axial stroke motion of the piston against the clamping force of the reference tension member by an inlet, and that can be connected by an outlet to the clamping press. The device further comprises a valve unit for controlling the application of the pressure medium to the clamping press, wherein the valve unit can be directly controlled by the stroke motion of the piston. The method according to the invention provides for clamping the tension member as a function of the clamping force of the reference tension member by the cylinder piston unit, the piston thereof holding the reference tension member in a predetermined stress state. When a uniform stress state is achieved in all tension members in the course of clamping the tension member by a clamping press, the inflow of the pressure medium to the clamping press is directly interrupted by the stroke motion of the piston.
