Tension-compression anti-falling bridge seismic mitigation and isolation support
The invention discloses a tension-compression anti-falling bridge seismic mitigation and isolation support which comprises a seismic isolation support core body, an upper support plate and a lower support plate, shock absorbers are arranged on the two sides of the seismic isolation support core body, each shock absorber comprises a cylinder body and a piston rod, a top plate is arranged at the top of each piston rod, and a spring arranged on each piston rod in a sleeving mode is arranged between each top plate and the corresponding cylinder body; 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 communicated 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 shock absorbers are arranged on the periphery of the support, the shock absorbers are used in cooperation with the hydraulic oil way through the springs, on the basis of first-stage shock absorption and shock insulation of an existing support, second-stage shock absorption and shock insulation are conducted through spring compression, and third-stage shock absorption and shock insulation are conducted through the hydraulic oil way; the impact of geological vibration, vehicle load and temperature stress on a bridge is avoided, the shock resistance and pressure resistance of the support are improved, and shear deformation of the support is avoided.
本发明公开了一种拉压防落桥梁减隔震支座，包括隔震支座芯体、上支座板和下支座板，隔震支座芯体两侧设置有减震器，减震器包括缸体和活塞杆，活塞杆顶部设置有顶板，顶板和缸体之间设置有套装在活塞杆上的弹簧；缸体内下部侧壁上设置有环形槽，缸体内设置有活塞、储油腔和出油槽，缸体侧壁上设置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；本发明通过在支座四周设置有减震器，其中减震器采用弹簧和液压油路配合使用，在现有支座一级减震和隔震基础上，利用弹簧压缩进行二级减震和隔震，利用液压油路进行三级减震和隔震，解决了地质振动、车辆载荷和温度应力对桥梁的冲击，提高支座抗震抗压能力，避免支座剪切变形。
