Device for removably fixing an internal structure to a circular wall inside an envelope

摘要

A device for the detachable fixing of an internal structure to a circular wall of a pipe or container. The device comprises one or more deformable annular members having blocks regularly distributed over its periphery. The application of radial forces between the blocks reduces the diameter level therewith and makes it possible to fit and remove the device. Application more particularly to the fixing of internal structures in the primary circuit of pressurized water reactors.
