Abstract
A cryostat, in particular for superconductive magnets, comprising different components nested in each other, one of them forming an outer shell and at least another one forming a tank arranged in the latter for receiving a coolant, and comprising further tension bars for interconnecting each inner component with its respective adjacent outer component, the said tension bars containing reinforcing fibers and being equipped at their ends with tie rods by means of which they are fixed to the respective component. A bond of high strength is achieved between the tension bars and tie rods due to the fact that the tie rods are provided with an outwardly widening bore, that each end of each tension bar is arranged in the bore in such a manner that the ends of the reinforcing fibers, being spread apart and impregnated with a glue, are located at the wider end of the bore. The widening tension bars, which are passed through the tie rods, have the effect that the connection is subjected, preferably, to pressure and shearing forces, whereby the tensile strength is prevented from dropping suddenly if the breaking tension should be exceeded.
