Arch deck bridge seismic mitigation and isolation support
The invention discloses an arch deck bridge seismic mitigation and isolation support which comprises a support body, an upper support plate, a lower support plate and shock absorbers. The support body comprises an upper support body, a lower support body and a spherical crown lining plate, each shock absorber comprises a cylinder body, a piston rod and a top plate, and a spring is arranged between the top plate and the cylinder body; and an annular groove is formed in the side wall of the lower portion in the cylinder body, a piston, an oil storage cavity and an oil outlet groove are arranged in the cylinder body, an oil outlet hole connected with the oil outlet groove is formed in the side wall of the cylinder body, and an oil outlet mechanism is arranged between the oil storage cavity and the oil outlet groove. The spherical crown lining plate is arranged between the upper support body and the lower support body in the passing direction, the upper support body, the spherical crown lining plate and the lower support body are matched in a cambered surface mode, friction energy dissipation can be performed in the vehicle passing direction in a seismic state, and the shock absorbers are arranged on the two sides of the passing direction of the support. Each shock absorber is used for solving the impact of geological vibration, vehicle load and temperature stress on a bridge in the passing vertical direction, the shock resistance and pressure resistance of the support are improved, and shear deformation of the support is avoided.
本发明公开了一种拱形桥面桥梁减隔震支座，包括支座体、上支座板、下支座板和减震器，支座体包括上支座体、下支座体和球冠衬板，减震器包括缸体、活塞杆和顶板，顶板和缸体之间设有弹簧；缸体内下部侧壁上设有环形槽，缸体内设有活塞、储油腔和出油槽，缸体侧壁上设有与出油槽连通的出油孔，储油腔和出油槽之间设有出油机构；本发明通过在上支座体和下支座体之间沿通行方向设置球冠衬板，利用上支座体、球冠衬板和下支座体之间构成弧面相配合，能够在地震状态时对车辆通行方向进行摩擦消能，支座通行方向两侧设置有减震器，利用减震器解决了地质振动、车辆载荷和温度应力在通行垂直方向对桥梁的冲击，提高支座抗震抗压能力，避免支座剪切变形。
