Speed locking type variable-curvature friction pendulum seismic mitigation and isolation support
The invention discloses a speed locking type variable curvature friction pendulum seismic mitigation and isolation support, which comprises a support consisting of an upper seat plate, a spherical crown lining plate, a damping spherical pendulum and a bottom basin, and is characterized in that a flange is arranged at the top of the damping spherical pendulum, and the spherical crown lining plate and the flange of the damping spherical pendulum are buckled in a bulge by the upper seat plate; a gap of a lateral displacement friction pair is formed between the flange and the inner wall of the bulge; the lateral displacement friction pairs are lateral sliding plates which are respectively arranged on the inner walls of the bulges and the flanges; the lug base B is hinged to a hanging lug B of the speed locker through a strip-shaped long hole with the two semicircular ends, and transverse displacement of the support is achieved. Compared with the prior art, the speed locking type friction pendulum seismic mitigation and isolation support has the function of displacement in the transverse bridge direction under the action of a conventional load, the situation that the speed locking type friction pendulum seismic mitigation and isolation support is only applied to a bridge without displacement requirements in the transverse bridge direction is avoided, the use range of the speed locking type friction pendulum seismic mitigation and isolation support is widened, the structure is simple, the manufacturing cost is low, installation is convenient and fast, and practicability is high. Good economic practicability and application prospects are realized.
本发明公开了一种速度锁定型变曲率摩擦摆减隔震支座，包括由上座板、球冠衬板、减震球摆和底盆组成的支座，其特点是减震球摆顶部设有凸缘，上座板将球冠衬板和减震球摆的凸缘扣合在凸起内，凸缘与凸起的内壁之间设有侧向位移摩擦副的间隙缝；所述侧向位移摩擦副为分别设置在凸起内壁和凸缘上的侧向滑板；所述B耳座采用两端为半圆的条形长孔与速度锁定器的B挂耳铰接，实现支座的横向位移。本发明与现有技术相比具有在常规荷载作用下横桥向位移的功能，避免了速度锁定型摩擦摆减隔震支座仅应用于横桥向无位移要求的桥梁中，拓宽了速度锁定型摩擦摆减隔震支座的使用范围，结构简单，制造成本低，安装便捷，具有良好的经济实用性和应用前景。
