Description
Technical field
The utility model belongs to seismic isolation device technical field more particularly to a kind of adjustable girder falling, collision prevention girders subtract
Earthquake isolating equipment.
Background technique
Earthquake can generate destruction to bridge structure --- fall beam destruction and impact wreckage.It falls beam destruction and refers to the upper of bridge
Portion's structure and the substructure for supporting it are detached from, i.e., girder is detached from from bridge pier or Abutment, cause that girder is hanging, fractures, or pendant
The phenomenon that falling.Impact wreckage refers to the bridge superstructure between adjacent, i.e. gap between girder is fully compressed, and phase occurs
The phenomenon that mutually colliding, causing end of main beam fragmentation.
When traditional anti-fall, collision prevention girders mechanism is limited to rigid member greatly and plays a role, since hardness pulls and hardness is touched
It hits, it is impaired that beam body can be made, and then lead to anti-fall, anticollision mechanism failure.To overcome anti-fall, anticollision device, collision-prevention device the hard defects of tradition and disadvantage
End, a kind of completely new anti-fall, anticollision new device come into being.By two adjacent beam body strings connecting rod together, solid in the device
