Friction pendulum type collaborative anti-seismic bridge structure
The invention belongs to the technical field of anti-seismic bridges, and discloses a friction pendulum type collaborative anti-seismic bridge structure which comprises a main beam body, a cover beam, a friction pendulum support, a friction pendulum type check block and a supporting check block. The main beam body is arranged above the cover beam in a sliding manner through the friction pendulum support and the supporting stop block; friction swing type check blocks are arranged on the two sides of the cover beam and used for forming a cavity for containing transverse swing of a main beam body on the cover beam. According to the friction pendulum type cooperative bridge anti-seismic structure, when an earthquake comes, the main beam body swings back and forth relative to the cover beam, so that earthquake energy is dissipated, and the purpose of seismic isolation and reduction is achieved; meanwhile, swing of the main beam body is further limited through the friction swing type stop block, and the danger that the main beam body overturns and falls off is reduced; and the self-resetting function of the bridge can be realized after the earthquake, so that the resetting procedure after the earthquake is saved, and the maintenance cost is reduced.
本发明属于抗震桥梁技术领域，公开了一种摩擦摆式协同抗震桥梁结构，包括主梁梁体、盖梁、摩擦摆支座、摩擦摆式挡块以及支承挡块；所述主梁梁体通过摩擦摆支座以及支承挡块滑动式设置于盖梁上方；所述盖梁两侧设有摩擦摆式挡块，用于在所述盖梁上形成容纳主梁梁体横向摆动的型腔。通过本发明的摩擦摆式协同桥梁抗震结构，在地震来临时，通过使主梁体相对于盖梁来回摆动，从而耗散地震能量，实现减隔震目的；同时通过摩擦摆式挡块进一步限制主梁梁体的摆动，降低主梁梁体倾覆和脱落的危险；震后也可以实现桥梁自复位功能，节省了震后的复位工序，降低了维护成本。
