In use, its operating principle is as follows respectively for the utility model:
Slide up and down plate to be fixedly connected with the agent structure of bridge, construction work, load-carrying members respectively, can the mode such as with bolts, welding realize.
The extension limit that lower slider board component is arranged by " U " type groove and basin assembly lower end, the end forms drawing-resisting device one, the extension limit that upper sliding plate assembly is arranged by " U " type groove and piston component upper end forms drawing-resisting device two, the extension limit that piston component lower end is arranged extends to the below of anti-pulling plate, and clearance filled buffer rubber gasket between this extension limit upper surface and anti-pulling plate soffit, and anti-pulling plate is fixed on end basin assembly formation drawing-resisting device three, by the buffer rubber gasket of the overall vertical filling between relative displacement extension limit upper surface and anti-pulling plate soffit of the restriction bearing of three groups of drawing-resisting devices, there is following effect: 1. in seat structure tension and compression stress conversion process, play cushioning effect, seat structure internal impact phenomenon is avoided to occur, 2. the viscoelastic property of rubber pad self is conducive to topple swing and the vertical motion that control bridge, construction work agent structure.
Under routine work load and the effect of common earthquake power, horizontal applied force is less than the shear strength of support shearing force pin, and bearing overall structure is in elastic state, is played the effect of fixed bearing by the Compact Mounts arranged.
Under the effect of rarely occurred earthquake power, horizontal applied force is greater than the shear strength of support shearing force pin, and shear pin structure is cut off is dissipated part seismic energy; Now, Compact Mounts destroys, and support body structure relatively slides up and down board component and starts to slide, and plays function of shock insulation; Steel damping element starts distortion, just produces damping energy dissipation, i.e. cushioning effect when distortion enters the steel plastic yielding stage; Under the double action of vertical load and side direction horizontal power, horizontal slip friction pair slides and produces certain frictional force, possesses the function of friction energy-dissipating.
Because the utility model adopts displacement type elastoplasticity steel damping structure, the change of bearing vertical force can not have an impact to horizontal steel damping hysteretic energy performance.
