FIELD: construction.SUBSTANCE: earthquake-resistant brick wall panel includes brick masonry of bricks with holes in the middle of width and on one fourth of length from brick end faces laid on mortar with alignment of holes into channels, and reinforcement bars passed through the channels with their stiff fixation on the end faces, by means of flat stop pieces as to thickness, which are equal to thickness of a mortar seam, and in the channels near the end faces of the panel there arranged are layers of vibration cushioning material of a U-type, which receive spatial vibration; with that, layers of vibration cushioning material are made from crushed worn-out tyre casings on a binder in the form of a rubber adhesive, liquid glass, or a polymer binding agent, and in every 8÷10 rows of bricks laid on mortar there welded are stiff stop pieces, and damping rods are elongated by application of welding; with that, mortar is poured into the channels of an intermediate zone with vibration cushioning chips from crushed tyre casings for formation of stiffer zones. Reinforcement bars are vibration cushioning, and each of them represents coaxially located cylindrical shells, between which there coaxially located are tubular damping elements from vibration cushioning material, to the ends of which there rigidly attached are flat stiff stop pieces, and the inner central cavity is filled with sand; with that, density of layers of vibration cushioning material is less than density of coaxially located cylindrical shells.EFFECT: increasing earthquake resistance of a brick wall panel.4 dwg |
