| Zusammenfassung: | A seismic joint damping device comprises a left damping unit and a right damping unit which are symmetrically arranged on concrete structures on two sides of a seismic joint. The left damping unit and the right damping unit comprise steel drums with inner sides embedded in the concrete structures, a piston with a piston rod is arranged in each of the steel drums, a spherical surface steel cover plate is arranged at the outer end of each of the piston rods, and a spring is arranged between each of the spherical surface steel cover plates and each of the concrete structures. The outer edge of each of the steel drums is flush with each of the concrete structures and is fixed through an arranged annular steel drum cover plate, and a spring is arranged between each of the spherical surface steel cover plates and each of the annular steel drum cover plates. At least two layers of the spherical surface steel cover plates are arranged at the outer end of each of the piston rod. The seismic joint damping device reduce |
