BUILDING BRICK Russian patent published in 2002 - IPC

FIELD: civil engineering, applicable for construction of buildings and structures in areas with a high seismic activity. SUBSTANCE: grooves are made in all the planes of the building brick, they converge to its outer surfaces and are positioned on the brick bed surfaces perpendicularly to the longer side, and on the stretching and bonder surfaces - perpendicularly to the bed ones. Production of grooves in the bed surfaces in a curve enhances the shearing strength of the masonry in the unbounded section. EFFECT: enhanced value of normal bonding and shearing strength in the masonry in bonded and unbounded sections by up to two times. 2 cl, 2 dwg
