KOCHETOV EARTHQUAKE-PROOF BUILDING STRUCTURE Russian patent published in 2016 - IPC E04H9/02 E04B1/92 

FIELD: machine building.

SUBSTANCE: in an earthquake-proof building structure containing the building framework with a foundation in a basement with a vibration insulation system, carrying walls with a surrounding structure in the form of a floor and ceiling lined with sound-absorbing structures, window and door apertures, and separate sound dampers, containing the framework, in which a sound absorbing material is located, and installed above noise equipment, the base carrying ceiling slabs have at points of securing to the carrying building walls the spatial vibration insulation system comprising horizontal vibration isolators, accepting vertical static and dynamic loads, and vertical vibration isolators accepting horizontal static and dynamic loads. The floor in rooms is made of a resilient base and has an installation slab made out of concrete reinforced by a vibration dampening material, that is installed on the base slab of the floor between storeys with cavities through layers of the vibration dampening material and waterproofing material with clearance relatively the carrying walls of the production room, wherein the cavities of the base slab are filled with the vibration dampening material, resilient base of the floor is made out of needled mats of a Vibrosil type based on silica or alumina-borosilicate fibres, the ceiling is made acoustic suspended, out of a rigid framework suspended to the ceiling of the production building with an installed inside the framework sound absorbing structure out of a sound absorbing material, wrapped by an acoustically transparent material, wherein lamps are installed in the framework. The cavities of the base slab between storeys are filled with a vibration dampening material, made in the form of a worm insertion out of a resilient polymer, for example, polyurethane, filled with a foamed polymer, for example, polyethylene or polypropylene, and the vibration insulation system of the foundation with the basement is made with its simultaneous separation by earthquake-proof welds from the neighbouring buildings and surrounding soil, and for protection against vertical vibrations the vibration insulators are installed in the wall pockets of the basement on areas of the strip foundation. Each set of the vibration insulation system comprises a metal plate, four vibration insulators, two emery paper sheets to exclude sliding of the foundation elements, and two support reinforced concrete blocks, wherein for the buildings protection against horizontal vibrations spreading in soil there is the vibration insulation system over the vertical surfaces of the external walls of the basement at the level of the foundation and cover plate. Around the building there is a retaining wall, its abutments are connected with end faces of the carrying walls through the vibration insulators, that are installed in the pockets of the abutments, the building basement is made in the form of a spatial frame structure out of monolith reinforced concrete with included in the frame cover plate and partitions, and reinforced by the partitions above the door and other apertures upon the permanent rigidity of the partitions. The foundation is made as a string crosswise structure with the height of approximately 50 cm, projecting above the foundation slab-brace.

EFFECT: increased efficiency of the building seismic resistance.
