EARTHQUAKE RESISTANCE BUILDING Russian patent published in 2015 - IPC E04H9/02 

FIELD: construction.

SUBSTANCE: earthquake resistance building comprises a vibration insulated foundation, horizontal and vertical bearing structures with a vibration insulation system, internal partitions, a building roof, and also door and window openings with strengthening, base bearing slabs are equipped in areas of their fixation to bearing walls of the building with a system of spatial vibration insulation, the floor in premises is made on an elastic foundation. The system of foundation vibration insulation with a basement floor is arranged with its simultaneous cutting of antiseismic-type from adjacent buildings and surrounding soil, and for protection against vibrations of vertical direction the vibration insulators are installed into niches of basement floor walls onto areas of a strip footing, and each set of the vibration insulation system comprises a metal board, four vibration insulators, two sheets of sanding paper to exclude the possibility of sliding of foundation elements and two support reinforced concrete blocks, and for building protection against vibrations of horizontal direction, spreading in soil, there is a system of vibration insulation on vertical faces of external walls of the basement floor at the level of the foundation and slab, at the same time around the entire building there is a retaining wall, buttresses of which are connected with ends of the bearing walls via vibration insulators, which are installed in niches of buttresses, besides, the basement floor of the building is made in the form of a spatial frame structure from solid reinforced concrete with a slab and partitions included into the frame, and also reinforced links above door and other openings with invariable stiffness of partitions. The foundation is made in the form of a strip cross structure with height of around 50 cm, protruding above the foundation screed slab. Each of vibration insulators is made as beaded and meshed, comprising a base, an elastic meshed element and beads interacting with bushings, the base is made in the form of a plate with fastening holes, the meshed elastic element, with its lower part resting against the base and fixed by the lower bead, stiffly connected to the base, and by the upper part fixed with an upper pressing bead, rigidly connected to a centrally located piston, covered with a gap, a coaxially arranged cartridge, rigidly connected to a base, and between the lower end of the piston and the bottom of the cartridge there is an elastomer, for example, from polyurethane. Density of the meshed structure of the elastic meshed element is in the optimal range of values: 1.2 g/cm³ ÷ 2.0 g/cm³, besides, the material of wire in elastic meshed elements is steel of EI-708 grade, and its diameter is in the optimal range of values 0.09 mm ÷ 0.15 mm, and density of the meshed structure of external layers of the elastic meshed element is 1.5 times more than density of the meshed structure of internal layers of the elastic meshed element.

EFFECT: reinforcement of building or facility structures, reduction of their vulnerability under effect of wind loads and earthquakes, increase of their seismic safety, durability and residual resource.
