ACOUSTIC STRUCTURE FOR PRODUCTION PREMISES Russian patent published in 2013 - IPC E04B1/84 

FIELD: construction.

SUBSTANCE: acoustic structure of production premises comprises a shop carcass, bearing walls with enclosures in the form of a floor and a ceiling, which are lined with sound-absorbing structures, window and door openings, and also single-piece sound absorbers, comprising a frame, where sound-absorbing material is arranged, and installed above noisy equipment. The floor structure is made on an elastic base and comprises a locating slab made of concrete reinforced with a vibration damping material. The locating slab is installed on two rigidly connected base plates of the floor slab of higher strength and seismic resistance with cavities, via layers of vibration damping and hydraulic insulating material, with a gap relative to bearing walls of a production room. Layers of vibration damping and hydraulic insulating material are made with flanging tightly adjacent to bearing structures of walls and the basic bearing floor slabs. A layer of the vibration damping material is laid between base plates of the floor slab. Cavities of base plates are arranged in a staggered order and are filled with vibration damping material, for instance, foamed polymer, polyethylene or polypropylene.

EFFECT: invention makes it possible to increase efficiency of noise attenuation, strength and seismic resistance of a building.
