QUAKEPROOF BRICK WALL PANEL Russian patent published in 2015 - IPC E04C2/04 E04H9/02 

FIELD: construction.

SUBSTANCE: invention relates to construction of buildings and structures in quake-prone areas. In a quakeproof brick wall panel comprising brickwork from bricks with holes in the middle of the width and at one quarter of the length from brick ends, laid onto mortar with matching of holes into channels, and reinforcement rods pulled through channels with their stiff fixation at the ends, by means of flat stops along thickness, equal to thickness of the mortar joint, and in channels near the ends of the panel there are layers of vibration-damping material of U-shaped type that perceive spatial vibration, reinforcement rods are made as damping, and each of them represents a cylindrical damping element, to the ends of which flat stiff stops are stiffly attached, and the inner cavity is filled with a layer of vibration-damping material, for instance, sand, at the same time density of the vibration-damping layer is less than the density of the outer cylindrical shell of the damping element, besides, layers of vibration-damping material structurally made as U-shaped and perceiving spatial vibration, are made of ground worn car tyres on a binder in the form of rubber glue, liquid glass or polymer binder, and at every 8-10 rows of bricks laid on mortar stiff stops are welded, and damping rods are extended using welding, besides, mortar with vibration-damping crumb is poured into channels of the middle zone to form stiffer zones, and reinforcement rods are made damping, and each of them represents coaxially arranged cylindrical shells, between which there are tubular damping elements placed coaxially from vibration-damping material, to the ends of which flat stiff stops are rigidly attached, and the inner central cavity is filled with sand, at the same time density of layers of vibration-damping material is less than density of coaxially arranged cylindrical shells.

EFFECT: increased earthquake stability of a brick wall panel by increased damping.
