FIELD: construction.
SUBSTANCE: invention relates to a coupling joint of reinforcement rods of periodic profile in the constructed conditions. In joint of reinforcement rods of periodic profile by means of couplings and lock nuts with cylindrical inner surface with thread and mating thread on end sections of reinforcement rods connecting the keys of the lock nut with one of the end sides are made with cone-shaped narrowing of the end section, repeating the shape and geometric dimensions of the flared end of the cylindrical cavity of the coupling.
EFFECT: technical result is higher accuracy of assembly and reliability of joints of reinforcement rods.
