Description
Technical field
The present invention relates to the realm of building construction, more particularly to a kind of big shake lower caging device of base isolation bearing.
Background technology
Current rubber earthquake isolation support has a disadvantage that：
1）Base isolation bearing is mainly to absorb energy by deformation of its rubber layer in seismic process, and it is upward to reduce energy
The transmission of portion's structure, to reduce the extent of the destruction of superstructure.But the deformation of rubber has certain limit, works as earthquake
When intensity is especially big, it is possible to which it is more than its deformation limit to lead to rubber earthquake isolation support horizontal displacement, at this point, shock isolating pedestal not only resists
Side rigidity is entirely ineffective, and since the effective compression area of bearing constantly reduces, vertical bearing capacity can also substantially reduce, structure meeting
There is the possibility caved in or toppled suddenly.
2）Base isolation bearing is usually located at ground level hereinafter, in dark moist environment, and rubber exists by moist empty
The risk of gas mineral corrosion when level of ground water is higher it is also possible to the danger directly impregnated by underground water, or even also has
The bearing capacity of shock isolating pedestal may be bitten to reduce by animals such as mouse.
Invention content
High, etch-proof base isolation branch that in order to compensate for the shortcomings of the prior art, the present invention provides a kind of anti-seismic performances
The big shake lower caging device of seat.
The present invention is achieved through the following technical solutions：
A kind of big shake lower caging device of base isolation bearing, it is characterized in that：Including pedestal, the pedestal is equipped with rubber vibration isolation branch
, there is a circle steel plate around the rubber earthquake isolation support, the steel plate upper and lower side is tightly connected with ground beam and pedestal respectively, described
It is the rigid retaining structure with buried depth around pedestal, there are spacing between the rigidity retaining structure and ground beam, described
It is equipped with damping system between steel plate and rigid retaining structure.
The rigidity retaining structure is high strength RC structure.
The steel plate is waterproof, etch-proof steel plate.
The damping system includes several radially distributed springs, and the spring one end welds on the steel plate, one end
It is anchored in rigid retaining structure.
The spring shares two circles.
The beneficial effects of the invention are as follows：
1）The present invention uses the setting limiting device proposed by the present invention at the peripheral determining deviation of rubber earthquake isolation support, works as under big shake
When rubber earthquake isolation support horizontal distortion is more than its flexible deformation, just start to collide with steel plate, due to being equipped with spring behind steel plate
Damping system, just push the spring deforms rubber earthquake isolation support together, and spring is as second defence line at this time, can and rubber vibration isolation
Bearing acts on absorption seismic energy simultaneously.When deformation continues to increase, when spring is compressed into the limit, rubber earthquake isolation support is fixed
The rigid retaining structure of spring limits, it is made no longer to generate horizontal displacement, avoids rubber earthquake isolation support entirely ineffective.
2）The steel plate that the present invention uses is a kind of waterproof, etch-proof steel plate, and rubber earthquake isolation support part is made to form one
A closed space.And the spacing of itself and isolation rubber meets the requirement of caoutchouc elasticity deformation.When small shake, when rubber vibration isolation branch
Seat deformation range be no more than its flexible deformation when, steel plate can play it is waterproof and dampproof and prevent the toys such as mouse close to rubber every
Shake the effect of bearing；When big shake makes rubber earthquake isolation support deform more than its self-resetting capability, steel plate can play again makes rubber
Shock isolating pedestal is transmitted through the power come and evenly distributes to the effect of spring.
Description of the drawings
The present invention will be further described below with reference to the drawings.
Fig. 1 is the schematic cross-sectional view of the present invention；
Fig. 2 be Fig. 1 in A-A to cross section structure schematic diagram.
In figure, 1 pedestal, 2 rubber earthquake isolation supports, 3 steel plates, 4 springs, 5 rigid retaining structures, 6 ground beams.
Specific implementation mode

Including pedestal 1, rubber earthquake isolation support 2 is installed on pedestal 1, a circle steel plate 3 is installed around rubber earthquake isolation support 2, steel plate 3 is
Waterproof, anticorrosion steel plate, 3 upper end of steel plate are withstood on ground beam 6, and lower end is contacted with rubber earthquake isolation support 2, steel plate 3 respectively with ground beam 6
Closed processes are carried out with 1 junction of pedestal so that the rubber earthquake isolation support 2 in steel plate 3 is in a closed space, pedestal
It is rigid retaining structure 5 around 1, rigid retaining structure 5 is high strength RC structure, and base foundation has certain bury
Set depth, make its will not be transmitted through by rubber earthquake isolation support 2 in big shake come push dynamic sliding, rigid retaining structure 5
Upper end and ground beam 6 between there are certain spacing, avoid superstructure from normally settling and it had an impact；Rigid retaining structure
5 thickness determines that principle is：It will not be pushed under the horizontal thrust effect that rubber earthquake isolation support 2 passes over；Steel plate 3 with just
Property retaining structure 5 between be equipped with damping system, damping system includes several radially distributed springs 4, and spring 4 has certain
Rigidity, 4 one end of spring is welded on steel plate 3, and one end is anchored in rigid retaining structure 5.Shared two circle up and down of spring 4.
In addition to technical characteristic described in specification, remaining technical characteristic is technology known to those skilled in the art.
