REINFORCED BRICK MASONRY Russian patent published in 2011 - IPC E04B2/34 

FIELD: construction.

SUBSTANCE: reinforced brick masonry of a double-row system includes bricks laid in rows with seams tying, vertical and horizontal reinforcement, at the same time each row of masonry is formed by a combination of three outbond bricks, laid with a gap, and a pair of bonder bricks that adjoin their ends, which are laid one after another, besides, the rows are displaced one relative to another by 1/4 of a brick to form vertical through channels, where vertical reinforcement is installed, at the same time horizontal reinforcement in longitudinal direction is laid in gaps formed by outbond bricks, and in transverse direction the horizontal reinforcement passes through seams, besides, channels and seams with reinforcement are filled with cement mortar. Vertical reinforcement is arranged with helical ledges at outer surface, besides, both in longitudinal and transverse direction the vertical reinforcement is installed pairwise on masonry so that on the first (out of each pair) vertical reinforcement the tangent of helical ledges has clockwise direction, and on the second vertical reinforcement the tangent of helical ledges has counterclockwise direction. At the same time there is a continuous chain of pairwise vertical reinforcement, which compensates for seismic breaking forces in the reinforced brick masonry.

EFFECT: improved earthquake resistance of a structure by means of breaking forces wave balancing in reinforced brick masonry due to partial reduction of strain amplitudes in vertical pairwise elements of reinforcement.
