Description
Technical field
The present invention relates to a kind of shock isolating pedestals, and especially one kind is vertically from the laminated rubber damping bearing of tension and its construction
Method.
Background technique
Earthquake is to seriously endanger one of the important natural calamity of human survival, has unpredictability and sudden.Base
Plinth shock insulation is that Seismic Isolation of Isolation Layer together is arranged between building basis and superstructure, so that deformation is focused primarily upon Seismic Isolation of Isolation Layer, extends
The basic cycle of structure reduces transmitting of the seismic energy to superstructure, so that vibration of the superstructure component under earthquake
Dynamic response substantially reduces, and improves the security performance of building.Laminated rubber damping bearing is that a kind of vertical bearing capacity is high, horizontal rigid
Small, the biggish device of horizontal comparison feasible value is spent, it can reduce horizontal earthquake action and carry Vertical Earthquake Loads, be
Most earthquake isolating equipments is applied in engineering at present.
Laminated rubber damping bearing is manufactured by different laminated construction and technique, 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 uses one layer
One layer of sheet metal interaction of TR thin rubber is stacked, and due to constraining the difference of transversal deformability, rubber support tensile capacity is far smaller than
Anti-pressure ability.The extensional rigidity of laminated rubber damping bearing is smaller relative to compression stiffness, and support tensile capacity is poor, draws
It stretches stress and reaches 1-2MPa and surrender；The vertical rigidity of rubber support is bigger relative to horizontal rigidity, exists to geological process
The possibility of amplification, so that support is easy to produce tensile stress.Shock isolating pedestal earthquake motion act on when inside tensile stress overstep the extreme limit when,
Building has the possibility integrally toppled, therefore the limit of China " seismic design provision in building code " GB50010 clear stipulaties rubber support
Tensile stress is not less than 1MPa.For rubber support isolation structure, when structure depth-width ratio is larger or Vertical Earthquake Loads are larger
When, inevitably there is the case where tension in laminated rubber damping bearing, causes shock isolating pedestal to destroy, so laminated rubber shock insulation
Support tensile capacity deficiency seriously constrains its application in the biggish building of depth-width ratio and highly seismic region skyscraper.
To solve the problems, such as that laminated rubber damping bearing tensile property deficiency, the prior art generally use tension limiting device.
There are two main classes for tension limiting device: one kind is to be integrated tension limiting device and shock isolating pedestal setting, mainly uses rubber
The mode that support and tension shock isolating pedestal are used in combination, in order to further decrease the vertical rigidity of support, can also by support with
The series connection of the elastic devices such as disk spring, such tension shock isolating pedestal have the function of limitation shock isolating pedestal stretcher strain,
Enforcement difficulty is big, while increasing the horizontal rigidity of support, will affect horizontal shock-absorbing effect.It is another kind of be using horizontal seismic isolation with
The vertical mutually independent component of tension is used in combination, and forms compound tension shock isolating pedestal, tension limiting device is separately provided
Near shock isolating pedestal, and by optimizing its rigidity and joint gap value, limits stretching of the shock isolating pedestal under geological process and become
Shape, this kind of tension limiting device do not influence the horizontal performance of shock isolating pedestal.This tension limiting device not only needs to meet vertically
The requirement of extensional rigidity and bearing capacity, it is also necessary to adapt to the deformation of Seismic Isolation of Isolation Layer horizontal direction, therefore size is larger, influence original building
Function uses, and is only capable of arranging on a small quantity.Especially when isolation structure is located near Triggering seismic fault band, Vertical Seismic Action of Structures compared with
Greatly, in addition to the laminated rubber damping bearing of periphery, middle part laminated rubber damping bearing is also easy to appear tensile stress, above two at this time
Scheme is difficult to carry out.
Tension shock isolating pedestal requires support to have the function of horizontal seismic isolation and vertical tension simultaneously, so taking an examination when design
Consider: guaranteeing the bearing capacity of support；The reset capability of horizontal seismic isolation and shake rear support；The realization of support tension function.Sufficiently to send out
The performance for waving laminated rubber damping bearing avoids laminated rubber damping bearing from bearing unfavorable pulling force, and being badly in need of one kind prevents lamination
The device of the vertical tension of rubber earthquake isolation support.
Summary of the invention
The object of the present invention is to provide a kind of band can lift-off device laminated rubber damping bearing and its construction method, to solve
The certainly technical problem of the vertical tensile capacity difference of laminated rubber bases, will also solve existing tension limiting device and shock isolating pedestal is arranged
The technical issues of it is big that there are enforcement difficulties when being integrated, and increases support horizontal rigidity, influences horizontal shock-absorbing effect will also solve existing
Size is larger when being set as independently using with shock isolating pedestal with the presence of tension limiting device, influence original building function use and only
The technical issues of capable of arranging on a small quantity.
