Assembly of prefabricated pre-stressed reinforced concrete elements solid with their reinforcements comprising linking means including at least one internally threaded cage, nuts in said cage, mounted on externally threaded parts directly or indirectly rigidly coupled to the reinforcements; the nuts abut against the cages by means of ball-and-socket bearings, thus making allowance for any misalignments of the elements. The reinforcements being solid with the concrete, this linking means affords for supplemental adjustment stress in particular elements only, whereby the assembly may be rendered statically indeterminate.
