Kind Code:
B2
Abstract:
The disclosure relates to an arrangement of bolt assemblies for connecting one element with another element, the bolt assembly comprising several bolt and hydraulic nut units which each consist of an outer nut and an inner nut which is exteriorly threaded for engagement with the outer nut and is interiorly threaded for engagement with the threads on the bolt, and of a hydraulic component comprising an annular cylinder and an annular piston, the hydraulic component being intended to be placed about the bolt between the nuts and one of the elements, possibly with an interjacent member placed between the element and the hydraulic component, and by means of which hydraulic unit, the bolt can be stretched via one of the nuts for permitting mounting of the other of the nuts in abutment against the hydraulic component which then serves as a form of washer between the nut and the element. The hydraulic components in adjacent hydraulic nut units are disposed substantially mechanically independently of each other for placing of each respective bolt in abutment against one of those elements which are to be connected to each other, or against a spacer element mounted between this element and the hydraulic component. Moreover, this element and the cylinder of each hydraulic unit is provided with communication passages which discharge at surfaces adjacent each other in this placing of the hydraulic component so that the passages are connected to each other by means of this placing.
