INDUSTRIAL ASEISMIC BUILDING Russian patent published in 2018 - IPC E04H9/02 E04B1/98 

FIELD: construction.

SUBSTANCE: invention relates to construction, namely to reconstruction, recovery or erection of aseismic buildings and structures. This is achieved by the fact that in an aseismic building, containing a vibration-insulated foundation, horizontal and vertical bearing structures with vibration insulation system, internal partitions, building roof, as well as door and window openings with reinforcement, basic bearing ceiling slabs are equipped with a damping system at their attachment to the building bearing walls, consisting of horizontal vibration isolators, receiving vertical static and dynamic loads, as well as vertical vibration isolators receiving horizontal static and dynamic loads. Each of the vibration isolators consists of rigidly interconnected rubber plates: the upper and lower, in which there are through holes arranged along the surface of the vibration isolator in staggered order, and form of the vibration isolators is square or rectangular, and their lateral faces are made in the form of curved surfaces of the n-th order, providing equal frequency of the vibration isolation system as a whole, wherein holes have shape providing frequency equality of vibration isolator, wherein each of the vibration isolators is equipped with shock-absorbing inserts, arranged in holes of each vibration isolators and made in the form of cylindrical damping element, to the ends of which flat elastic stops are rigidly attached, and the inner cavity is filled with a layer of a vibration damping material, for example sand, wherein the density of the vibration damping layer is less than the density of the outer cylindrical shell of the damping element. Each vibration isolator, installed between the metal plate and reinforced concrete beam, located at the building base, is made in the form of a symmetrical washer mesh vibration isolator, comprising the base, which is located in the middle part of the vibration isolator and is made in the form of a plate with mounting holes, and mesh elastic elements, upper one with an upper pressure washer and lower one with a lower pressure washer, are rigidly connected to the base by means of support rings, respectively, in the upper mesh elastic element, in the center, a dry friction damper is axisymmetrically located, designed as the upper press washer, rigidly connected to a centered ring enclosed by the axially located ring, which is rigidly connected to the base, as well as in the lower mesh elastic element, in the center, the dry friction damper designed as a lower press washer, rigidly connected to a centered ring enclosed by a coaxially located ring rigidly connected to the base is axially symmetrically located.

EFFECT: technical result is reinforcement of buildings or structures, their reduced vulnerability under action of wind loads and earthquakes, improved seismic safety, durability and service life.
