Description
Technical field
The present invention relates to subtract shock insulation apparatus field, and in particular to a kind of rod axial laminated rubber steel plate seismic isolation 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 the most serious country.Caused by city inner structure, equipment (such as cultural relics in the collection of cultural institution storage apparatus) destruction
Economic loss and casualties will cause huge impact to national security and social stability.Earthquake is due to that earth formation is in
In complicated stress state, with being continually changing for the earth's crust, when the effect of crustal stress exceedes the ultimate strength of somewhere rock stratum, rock stratum
Will occur unexpected fracture and the changing of the relative positions, so as to cause vibrations, and earth's surface be passed in the form of elastic wave, cause adjacent ground surface
Object with certain mass produces inertia force, when the shock resistance deficiency for this effect of inertia of resistance that object has in itself
When, object is destroyed.And when earthquake motion predominant period and object natural vibration period relatively when, the destruction of object just will
It is more serious.And the natural vibration period of object can be significantly changed by setting certain earthquake isolating equipment to object, so as to avoid ground
The predominant period of shake, so that significantly reduction acts on the inertia force of object, reduce destruction of the object under geological process, increase
Safety of the object under earthquake.
Traditional seismic isolation technology that subtracts is generally divided into two major classes：One class be by the setting of earthquake isolating equipment come extending structure from
Shake the cycle, reduce the earthquake response of superstructure；Another kind of is the device by setting power consumption in the junction on structure with basis,
Energy input of the earthquake to structure is consumed, so as to reduce the seismic energy being input in structure, the destruction of geological process is reduced.Mesh
It is preceding both subtract seismic isolation technology and achieve preferable application, but above-mentioned above two subtracts the isolation measure that vibration isolation way is taken
All it is, to reduce horizontal earthquake action as target, to be only able to meet horizontal vibration isolation as the bearing subtracted designed by vibration isolation target
The need for.But actual earthquake shows, axially influence of (vertical) earthquake to object be it is very important, in some cases, its
Effect can exceed horizontal earthquake action.Traditional shock isolation pedestal be typically all for horizontal direction carry out shock insulation, this cause tradition every
On the one hand shake pedestal is unsatisfactory for the requirement of axial shock insulation, on the other hand, in some cases, Axial Seismic can also be acted on and produced
Amplification.
