KINEMATIC SUPPORT FOR THE SEISMIC-BUILDING FACILITIES Russian patent published in 2018 - IPC E02D27/34 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction and is intended for buildings and structures under construction in seismically hazardous areas, or for objects having a special purpose. Kinematic support for an earthquake-proof building, the structure contains the upper and lower parts with supporting surfaces and with the mobile ball coupling located between them. Upper and lower parts are made with flat horizontal support surfaces, between which at least three balls are located at a distance from each other and in different directions. Upper and lower portions are interconnected by a prestressed thrust mounted to return the displaced portions of the support from the seismic ground from the traction force deflected to the initial position by the horizontal component. Prestressed draft is located between the balls in the conical holes arranged in the upper and lower parts of the support and directed towards each other by the bases. Supporting surfaces of the upper and lower parts are made of steel sheets installed in the base or foundation as embedded parts of reinforced concrete elements.

EFFECT: technical result consists in expanding the arsenal of technical means used to protect buildings and structures from seismic influences, increasing the effectiveness of the seismic protective function of the building, the construction, excluding the occurrence of vertical forces on the building and on the foundation, as well as ensuring the reliability and stability of kinematic supports, while maintaining their effectiveness, reduce seismic forces and limit the movement of buildings in earthquakes with a wide range of frequencies.
