FIELD: metallurgy.
SUBSTANCE: invention relates to prefabricated metal structures with protection against unauthorized disassembly and can be used in mounting and dismantling of polyhedral metal supports of overhead transmission lines. Method of dismounting anti-vandal threaded joint, comprising swirled and tightened threaded connection with bolt head and nut with smooth side surfaces, on smaller base of which in blind cylindrical grooves there are ratchets with engaged teeth, wherein removal of vandal-proof threaded connection is performed with equipment using seams of welded joint with strength, providing force of nut screwing from bolt with keys for welded nuts-keys - one is retained, anti-vandal thread joint is turned away and disconnected by another one.
EFFECT: technical result of the invention is removal of anti-vandal threaded connection for further installation for a new purpose.
