  • Patent number: 5071261
    Abstract: An earthquake bearing with a spherical ball (26) located between two elastomer layers (18,19) in the shape of half-shells. The elastomer layers each include a cylindrical elastomeric pad. The earthquake bearing further includes a spherical clearance (25) facing the ball (26), with bearing housings or halves (11,12) being mutually braced by elastomer bearings (24) in order to achieve compliant, progressive damping. This system is capable of gently moving out of the way both vertically and horizontally. The bearing halves (11,12) are prestressed by tension bars (23) which pass centrally through the bearings (24). The elastomer bearings (24) include of a plurality of columns defined by panes of elastomers and panes of steel. Outwardly directed head bolts (15) are held on the base plates (13,14) of the bearing housings (11,12) and are anchored into the adjoining components.
