KOCHETOV(S LOW-NOISE ASEISMIC PRODUCTION BUILDING Russian patent published in 2016 - IPC E04H9/02 E04B1/84 

FIELD: construction.

SUBSTANCE: in a low-noise aseismic production building containing a building frame with a base, bearing walls with barriers in the form of a floor and a ceiling which are clad in sound-absorbing structures, window opening and doorways, and also piece sound absorbers containing a frame containing a sound-absorbing material, and which are installed above noisy equipment, basic bearing plates of the ceiling are provisioned in places of their fastening to bearing walls of the building with a system of spatial vibration insulation consisting of horizontally located vibroinsulators perceiving vertical static and dynamic loads, and also vertically located vibroinsulators perceiving horizontal static and dynamic loads, and the floor in the rooms is made on an elastic foundation and contains a mounting plate, made from concrete reinforced by a vibrodamping material which is installed on the basic plate of the interfloor ceiling with cavities through layers of the vibrodamping material and waterproofing material with the gap with reference to the bearing walls of the production room, and cavities of the basic plate are filled with a vibrodamping material which for example is made from a foam polymer, cavities of the basic plate of the ceiling are filled with a vibrodamping material made in the form of a spiral insert of an elastic polymer, for example polyurethane filled with a foam polymer, for example polyethylene or polypropylene, the base of the building frame is made with vibration insulation of a ferroconcrete plate consisting of interconnected ferroconcrete beams in the building foundation, which includes, at least, four vibroinsulators, installed between the metal plate and the ferroconcrete beam, located in the building foundation, integrated with, at least, eight tape foundation blocks that are peculiar "traps", and each of the metal plates is installed on, at least, three ferroconcrete thrusting columns, and between each tape foundation blocks and each of the ferroconcrete beams sandy pillows are installed, and under the vibroinsulators strain gages are installed which monitor settling of the vibroinsulators. The sandy cushions are installed in metal demountable holders, and each of the vibroinsulators consists of rubber plates which are rigidly connected among themselves: upper and lower in which through holes are made which are located on the vibroinsulator surface in a staggered order, and the vibroinsulators are made with a square or rectangular form, and their lateral sides are implemented in the form of curvilinear surfaces of the n-th order, providing the equifrequency of the vibration insulation system in general, while holes have the form in the cross section providing the equifrequency of the vibroinsulator and are filled with a vibrodamping material from an elastic polymer, for example polyurethane.

EFFECT: improvement of the noise suppression efficiency and seismic stability of the building.
