Description
Technical field
The present invention relates to subtract shock insulation apparatus field, and in particular to a kind of laminated rubber steel plate lead block damping rod axial subtract every
Shake device.
Background technology
China is located in two main earthquake zones-between Eurasian earthquake zone and circum-Pacific seismic belt, be in the world by
One of to earthquake damage country the most serious.Caused by structure, equipment (such as cultural relics in the collection of cultural institution storage apparatus) are destroyed in city
Economic loss and casualties will cause huge impact to national security and social stability.Earthquake is since earth formation is in
In complicated stress state, with the continuous variation of the earth's crust, when the effect of crustal stress is more than the ultimate strength of somewhere rock stratum, rock stratum
Unexpected fracture and the changing of the relative positions will occur, so as to cause vibrations, and pass to earth's surface in the form of elastic wave, cause adjacent ground surface
Object with certain mass generates inertia force, when the shock resistance for this effect of inertia of resistance that object itself has is insufficient
When, object destroys.And when the predominant period of earthquake motion and the natural vibration period of object relatively when, the destruction of object just will
It is more serious.And the natural vibration period of object can be significantly changed by the way that certain earthquake isolating equipment is arranged to object, to avoid ground
The predominant period of shake reduces destruction of the object under geological process, increases to significantly reduce the inertia force for acting on object
Safety of the object under earthquake.
Traditional seismic isolation technology that subtracts is generally divided into two major classes：One kind be by the setting of earthquake isolating equipment come extending structure from
It shakes the period, reduces the earthquake response of superstructure；Another kind of is the device to be consumed energy by the junction setting on structure with basis,
Consume earthquake reduces the destruction of geological process to the energy input of structure to reduce the seismic energy being input in structure.Mesh
It is preceding both subtract seismic isolation technology and achieve preferable application, but above two subtracts the isolation measure that vibration isolation way is taken and is all
To reduce horizontal earthquake action as target, it is only able to meet the need of horizontal vibration isolation as the bearing subtracted designed by vibration isolation target
It wants.But practical earthquake shows that influence of axial (vertical) earthquake to object is very important, in some cases, acts on
It can be more than horizontal earthquake action.Traditional shock isolation pedestal is typically all to carry out shock insulation for horizontal direction, this makes traditional Isolating Platform
On the one hand seat is unsatisfactory for the requirement of axial shock insulation, on the other hand, in some cases, can also act on Axial Seismic and generate amplification
Effect.
