Abstract

The invention relates to mounting of machine parts and can be used for attachment of machine parts by means of draw bolts or pin bolts at mounting of steam turbines, nuclear reactors, high pressure pumps, metallic constructive elements and similar. The invention can be used at profylactic work and repair work. The object of the technical solution is to simplify the construction, increase the reliability of the attachment, increase the accuracy of determining the elongation of the draw bolts or pin bolts, and decrease the weight, size and cost factors. This is achieved by utilizing power members (2), which have thermomechanical shape-memory and at the same time a deformation at transformation, which is direction orientated. The change between the state of shape of the power member (2) is caused by a heating device (3, 8).
