Abstract
The antiseismic device is used in the construction of building and structures in seismic areas. It absorbs and neutralizes any vertical or horizontal shifts. It is possible to achieve different characteristics depending on the concrete seismic area. The device is fitted between an upper (1) and basic (2) part of a two-section foundation and is in the form of a cantelever supporting rod (3) rigidily connected to the basic part (2) and to a round plate (4) in its upper end. The round plate (4) has a rounded upper surface (8) and is positioned inside a fixing element (5), fixed to the upper part (1) of the two-section foundation. The cantelever supporting rod (3) is made of at least two parts (6) tightly fiting each other along the surface (7) of the type of the screw ..................... The parts (6) are formed by means of slit or they are in the form of two separate parts twisted around each other.
