Description
Technical field
The utility model relates to a kind of laminated rubber damping bearing, especially a kind of laminated rubber shock insulation of tension self-shield
Pedestal configurations.
Background technique
Laminated rubber bases shock insulation is the earthquake isolating equipment being most widely used at present, wherein on upper connecting cover plate and building
Portion's structure is connected, and lower connecting cover plate is connected with building basis, to transmit horizontal shear.Laminated rubber damping bearing has level
The characteristics such as rigidity is low, vertical compression rigidity and compression bearing height, but its extensional rigidity and tensile capacity are obviously insufficient.Work as knot
When structure depth-width ratio is larger or Vertical Earthquake Loads are larger, inevitably there is the case where tension in laminated rubber damping bearing, by
Rubber layer internal microstructure is destroyed after drawing, subtle hole occurs, not only influences the vertical tension and compression rigidity of shock isolating pedestal
With bearing capacity, support horizontal distortion performance is also seriously affected, the elastic property of support is reduced.When support generates tension damage again
When compressing again under earthquake reciprocating, the compression Stiffness Drop of support and is pressurized and holds down to the half or so of former rigidity
It carries power sharply to decline, when deformation further increases, steel plate layer and rubber layer generate tearing, cause superstructure to exist and topple
It is dangerous.It is high-rise in the biggish building of depth-width ratio and highly seismic region that laminated rubber damping bearing tensile capacity deficiency seriously constrains it
Application in building.
In order to solve this problem technical staff generally takes following measures:
One, resistance to plucking measure, such as setting tension reinforcement, wirerope, prestress wire are set in rubber earthquake isolation support.
Or do the connecting plate of shock isolating pedestal greatly, steel plate and tension limiting device are set on support connecting plate, limited by rigid baffle
The vertical displacement of rubber support processed, allows support and the common stress of rigid baffle, improves its extensional rigidity and tensile bearing capacity.It is this kind of
Device easily leads to shock isolating pedestal level and couples with vertical mechanical property, and pedestal configurations are complicated, and enforcement difficulty is big, while increasing branch
The horizontal rigidity of seat, damping effect decrease.
Two, rubber earthquake isolation support is connected with devices such as disk springs, the vertical tensible rigidity of disk spring is less than rubber
Shock isolating pedestal extensional rigidity, after the two series connection, whole tensible rigidity is smaller.Such tension shock isolating pedestal construction is multiple
Miscellaneous, enforcement difficulty is big, can generate biggish vertical displacement, it is possible to the occurrence of will cause local instability.Tension shock insulation
Support requires support to have the function of horizontal seismic isolation and vertical tension simultaneously, so being considered as when design: guaranteeing the carrying of support
Power；The reset capability of horizontal seismic isolation and shake rear support；The realization of support tension function；Avoid support horizontal rigidity and vertical rigidity
It couples.Pedestal configurations complexity is used in series using disk spring and rubber support, enforcement difficulty is big, while increasing support
Horizontal rigidity, will affect horizontal shock-absorbing effect.
Three, simple anti-pulling device is set near shock isolating pedestal.Easy anti-pulling device is that the top of two pull rods is fixed
With on the isolation structure beam of superstructure one, using the anti-pocket of cross bar in the lower part of the dedicated beam of shock insulation, support is drawn for lower end
It will lead to support when power and significantly deformation occur, contact the cross bar of anti-pulling device with the dedicated beam of shock insulation, and overturning moment draws
The vertical tension risen is transmitted on isolation structure beam through pull rod, it is ensured that shock isolating pedestal is not in excessive pulling force, guarantees structure
Safety.Resistance to plucking limiting device is separately provided, and by optimizing its rigidity and joint gap value, limits shock isolating pedestal in geological process
Under stretcher strain, this kind of anti-pulling device do not influence the horizontal performance of shock isolating pedestal.
Easy anti-pulling device not only needs to meet the requirement of vertical extensional rigidity and bearing capacity, it is also necessary to adapt to Seismic Isolation of Isolation Layer
The deformation of horizontal direction causes isolation structure beam size larger, influences the use of original building function.Rubber earthquake isolation support is horizontal big
In the state of deformation, shock isolating pedestal additional bending moment due to caused by horizontal force, which will appear, slightly to topple, and leads to simple anti-pulling device
Gap between cross coupling becomes larger, and when isolation structure depth-width ratio is close to 4.0, and is located near Triggering seismic fault band, structure is vertical
Geological process is larger, and since Vertical Earthquake Loads do not cause structure to be toppled, but still it is larger to cause shock isolating pedestal to occur
Tensile stress, with horizontal earthquake generate overturning moment be superimposed, in addition to the laminated rubber damping bearing of periphery, middle part laminated rubber every
Shake support is also easy to appear tensile stress, and above scheme is difficult to carry out at this time.
