LOW-NOISE EARTHQUAKE-RESISTANT MANUFACTURING BUILDING Russian patent published in 2016 - IPC E04B1/84 

FIELD: acoustics.

SUBSTANCE: invention relates to industrial acoustics. Invention presupposes the following: in a low-noise aseismic production building containing a building frame with a base, bearing walls with enclosures in the shape of a floor and a ceiling, lined with sound-absorbing structures, window and door openings, as well as custom-made sound absorbers containing a frame with sound-absorbing material, and arranged over noisy equipment base bearing floor slabs are equipped, in places of their attachment to carrying building walls, with a spatial vibration isolation system consisting of horizontally arranged vibration isolators accepting vertical static and dynamic loads, as well as vertically arranged vibration isolators accepting horizontal static and dynamic loads; at that, the floor in the rooms is made on an elastic base and comprises a mounting plate made of concrete reinforced with vibration damping material which is installed on the base plate of the inter-floor slab with cavities through layers of vibration damping material and waterproofing material with a clearance relative to bearing walls of the production room. Note here that cavities of the base plate are filled with vibration damping material, for example foamed polymer.

EFFECT: technical result: gain in performance of noise absorption and earthquake resistance of buildings.
