ROD FOR BRICK PANEL Russian patent published in 2018 - IPC E04C2/04 

FIELD: building.

SUBSTANCE: invention relates to construction in earthquake-prone areas of buildings and structures. Rod for the brick panel is made damping, in the form of coaxially arranged cylindrical shells, between which co-axially located tubular damping elements of the vibration damping material, to the ends of which are rigidly attached flat rigid stops, density of the layers of the vibration damping material is smaller than the density of the coaxially arranged cylindrical shells, the coaxially arranged cylindrical shells of the reinforcement damping rods being perforated, and polyurethane is used as vibration dampening material of tubular damping elements. Flat rigid stops that connect the end surfaces of coaxially located cylindrical shells are made of combined, consisting of at least three layers: lower and upper are rigid, and the third layer located between them is made damping, and the inner cavity is filled with a set of at least two damping disks mounted on an elastic axle coaxially disposed with the cylindrical shell, and between the damping disks there is at least one cylindrical helical spring. As a vibration damping material of the cylindrical shell of tubular damping elements, polyethylene or polypropylene is used, and the internal cavity between damping disks and flat rigid stops is filled with crumb of vibration damping materials: rubber, cork, foam plastic, nylon, foamed polymer, plastic type "Schwim", with the size of fractions of crumb 1.5÷2.5 mm, filled with elastomer, for example polyurethane, or from a solid damping material in which sponge rubber is used, or a "Vibrosil" needle-punched material based on silica or aluminoborosilicate fiber, or a nonwoven vibro-damping material. Third layer of flat rigid abutments connecting the end faces of coaxially arranged cylindrical shells is made damping and consisting of a vibration damping material, for example polyurethane, or foamed polymer, or crumbs from vibration damping materials: rubber, cork, polystyrene, capron, foamed polymer, plasticizer type "Schwim", with the size of fractions of crumb 1.5÷2.5 mm, and is filled with an elastomer, for example polyurethane.

EFFECT: increased seismic resistance of brick wall panel.
