ACOUSTIC CONSTRUCTION FOR INDUSTRIAL PREMISES Russian patent published in 2018 - IPC E04B1/74 E04B5/00 E04F15/18 

FIELD: acoustics.

SUBSTANCE: invention relates to industrial acoustics, particularly, to broadband acoustic suppression, and can be used in all sectors of national economy as means of noise protection. Acoustic design of production facilities contains the frame of the workshop, bearing walls with fences in the form of floor and ceiling, which are lined with sound-absorbing structures, window and door openings, as well as piece sound absorbers, containing a frame in which the sound-absorbing material is located, and installed above the noisy equipment. Design of the floor is made on an elastic base and contains an installation plate made of reinforced concrete, which is installed on two, rigidly interconnected, base slabs of interfloor overlap with increased strength and seismic resistance with cavities through layers of vibration damping and waterproofing material with a clearance relative to the production room bearing walls. Layers of the vibration damping and waterproofing material are made with a flange that fits closely to the bearing structures of the walls and the base load-bearing slabs. Between the base plates of the interfloor overlap a layer of vibration damping material is laid. Cavities of the base plates are staggered and filled with a vibration damping material, for example, a foamed polymer, polyethylene or polypropylene. Walls are covered by sound-absorbing structures.

EFFECT: invention makes it possible to increase the strength and seismic stability of a building, as well as the effectiveness of noise attenuation.
