Spherical steel support with bidirectional elastic rigidity

A spherical steel support with bidirectional elastic rigidity is characterized by comprising a base; a lower support body is mounted on the bottom face of an inner cavity of the base and can slide on the bottom face of the inner cavity of the base; and retaining blocks are arranged in the inner cavity of the base and can limit the sliding distance of the lower support body. The spherical steel support with the bidirectional elasticity and recoverable and horizontal sliding functions not only has vertical bearing and rotating functions of a traditional spherical steel support, but also has the functions of enabling the structure which moves horizontally to restore automatically reset, adsorbing shock and dissipating energy. 种具有双向弹性刚度的球形钢支座，其特征在于：它包括底座，所述底座内腔底面上装有下支座，所述下支座能够在底座内腔底面上滑动，所述底座内腔上设有挡块能够限制下支座的滑动行程；本发明具有双向弹性可恢复的水平滑动功能的球形钢支座，使该支座既具有传统球形钢支座的竖向承载和转动功能，又具有使结构水平位移自动复位和减震耗能的功能。
