Abstract: A method for installing a prestressing element in an anchor block, in which the prestressing element is attached to a holder, includes the holder being moved to the anchor block, the prestressing element being introduced into a through-opening of the anchor block, and the prestressing element being fixed to the anchor block. The holder can be attached to the prestressing element at a distance which is selected so that the length of the projection of the prestressing element on the side of the holder facing the anchor block is greater than the length of a portion of the prestressing element, which is required for introducing the prestressing element into the through-opening and fixing the prestressing element to the anchor block.

Abstract: 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.
