Abstract: A method for determining an axial tensile force applied to a component, includes fastening the component in place and applying axial tensile force to the component from a free end of the component by a loading device, having a loading body with a central axial main threaded bore and a plurality of secondary threaded bores distributed evenly along the circumference and having loading screws, which are screwed into the secondary threaded bores. The loading body is screwed onto the free end of the component and the loading screws are loaded against a stationary abutment in the direction of the fastening. The axial tensile force applied to the component is determined. Deformation of the loading body transverse to the axial direction of the loading body is sensed and the axial tensile force applied to the component is determined from the deformation of the loading body.

Abstract: An annular clamping nut which is provided for being placed onto the end of a tie bar, in order to brace the latter, and which has in addition to a central recess for receiving the tie bar parallel to a longitudinal direction passages at uniform radial spacings in the ring circumferential direction which are directed parallel to the longitudinal direction of the central recess and are provided for receiving clamping screws. An external thread is provided on the outer surface of the clamping nut, which outer surface is arranged on a side which lies substantially opposite the wall of the central recess, which external thread runs substantially in the ring circumferential direction of the outer surface.

Abstract: A compression generator uses a plurality of jackbolts threadedly engaged at a spaced apart relation about a bolt circle in a main core element. The main core element is releasable interlocked by threads, bayonet connection or other form of fasting system with the mounting element forming a fixed part of the mechanical connection. The jackbolts torqued to generate a pushing force in an axial direction for compressing a moveable part of the mechanical connection against a compression seat for forming a mechanical connection between juxtaposition fixed and moveable parts.
