KOCHETOV LOW-NOISE STRUCTURE FOR EARTHQUAKE-RESISTANT INDUSTRIAL BUILDINGS Russian patent published in 2016 - IPC E04B1/84 

FIELD: acoustics.

SUBSTANCE: invention relates to industrial acoustics. Low-noise structure for earthquake-resistant industrial buildings contains a building frame with base, bearing walls with enclosures of floor and ceiling, which are lined with sound-absorbing structures, window and door openings, as well as single sound dampers, containing a frame, wherein sound-absorbing material is placed, and arranged over noisy equipment, basic bearing ceiling slabs are equipped with a damping system at their attachment to the building bearing walls, consisting of horizontal vibration isolators, accepting vertical static and dynamic loads, as well as vertical vibration isolators accepting horizontal static and dynamic loads. At that, each vibration isolator installed between the metal plate and the reinforced concrete girder, located in the base of the building, is made in the form of symmetrical washer mesh vibration isolator, containing a base, that 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, top with upper pressure washer and bottom, with lower pressure washer, are rigidly connected to the base by means of support rings, respectively. In the upper mesh elastic element, in the centre, the dry friction damper is located axisymmetrically, configured in the form of upper pressure washer, rigidly connected with the central placed ring, male, by coaxially placed ring, which is rigidly connected to the base. In the lower mesh elastic element in the centre, the dry friction damper is located axisymmetrically, configured in the form of lower pressure washer, rigidly connected with the central placed ring, male, by coaxially placed ring, rigidly connected to the base.

EFFECT: technical result consists in efficiency improvement of noise suppression and seismic stability of the building.
