WALL BARRIER Russian patent published in 2010 - IPC E04C2/02 E04C5/03 

FIELD: construction.

SUBSTANCE: wall barrier includes external and internal layers joined by building mortar to form seams and separated by insulator, between which there is a reinforcement of metal rods in the form of flat reinforcement frame of attached longitudinal and z-shaped rods spatially arranged at an angle. Metal rods are arranged pairwise, and helical ribs are arranged on external surface, besides, on the first rod, of a pair of rods, helical ribs have clockwise direction of tangent rotation, and on the second rod helical ribs have counterclockwise direction of tangent rotation.

EFFECT: improved reliability and durability of reinforced concrete structures operation under near-critical conditions by means of optimisation of ratio of deforming properties of concrete and reinforcement by mutually oppositely directed longitudinally moving amplitudes of stresses along lengths of pairwise arranged metal rods of reinforcement.
