KOCHETOV SEISMIC RESISTANT BRICK WALL PANEL Russian patent published in 2018 - IPC E04C2/04 E04B1/98 

FIELD: construction.

SUBSTANCE: invention relates to construction in earthquake-prone areas of buildings and structures. Earthquake-resistant brick wall panel contains brickwork of bricks with holes in the middle of the width and one-quarter of the length from the ends of the brick, laid in the solution with the alignment of the holes in the channels, and the reinforcing bars, passed through the channels with rigid fixation at the ends, by means of flat stops in the thickness equal to the thickness of the mortar joint, and in the channels at the ends of the panel there are layers of the U-shaped type of vibration damping material, which perceive the spatial vibration, the reinforcing bars are made damping, and each of them is a cylindrical damping element to the ends of which rigid abutments are rigidly attached, and the inner cavity is filled with a layer of a vibration damping material, for example sand, density of the vibration damping layer is less than the density of the outer cylindrical shell of the damping element, layers of the vibration damping material, structurally made of U-shaped type and perceiving spatial vibration, are made of shredded worn out tires on a binder in the form of a rubber glue, a liquid glass or a polymer binder. Every 8÷10 rows of bricks laid on the solution are welded to hard stops, and the damping rods are elongated with the use of welding, and a solution is added to the channels of the middle zone with a vibration damping crumb from the shredded tires of automobile tires to form more rigid zones. Each of the reinforcing bars can also be coaxially disposed cylindrical shells, between which co-axially disposed tubular damping elements of a vibration damping material, to the ends of which are rigidly attached flat rigid supports, and the inner central cavity is filled with sand, density of the layers of the vibration damping material is less than that of the coaxially arranged cylindrical shells. In the inner cavity of the rods, which are a damping element filled with a layer of vibration damping material, a cylindrical helical spring is arranged to increase the seismic stability of the panel in the horizontal direction.

EFFECT: increased seismic resistance of brick wall panel.
