Description
Technical field
The utility model is related to structure and equipment and cultural relics in the collection of cultural institution field, and in particular to a kind of three-dimensional with arc track
Shock isolation pedestal.
Background technology
China is located in two main earthquake zones-between Eurasian earthquake zone and circum-Pacific seismic belt, be to be subjected in the world
Arrive one of earthquake damage country the most serious.In history, Yangtze River Delta and the Delta of the Pearl River once repeatedly occurred 6 grades with
On macroseism, in Beijing-Tianjin Bohai Rim, over nearly 300 years, just there is the violent earthquake of more than 7 grades averagely per 44 years.With
The quickening of urbanization process, substantial amounts of national wealth is quickly to city and group of cities area concentration.And China 1/3rd with
On the built or group of cities planned to build be located at it may happen that the area of more than 7 grades violent earthquakes.City inner structure, equipment and collection
The destruction of historical relic and the economic loss and casualties that cause will cause huge impact to national security and social stability.Earthquake
It is that with being continually changing for the earth's crust, the effect of crustal stress exceedes somewhere rock as earth formation is in complicated stress state
During the ultimate strength of layer, rock stratum will occur unexpected fracture and the changing of the relative positions, so as to cause vibrations, and be passed in the form of elastic wave
Earth's surface, causes the object with certain mass of adjacent ground surface to produce inertia force, this inertia of the opposing having when object in itself
When the shock resistance of effect is not enough, object is destroyed.And the natural vibration period of the predominant period and object for working as earthquake motion relatively connects
When near, the destruction of object just will be more serious.And by certain earthquake isolating equipment being arranged to object can significantly change object
Natural vibration period, so as to avoid the predominant period of earthquake, so as to significantly reduce the inertia force for acting on object, reduce object on ground
Destruction under shake effect, increases safety of the object under earthquake.
Traditional seismic isolation technology that subtracts is generally divided into two big class：One class be by the setting of earthquake isolating equipment come extending structure from
Shake the cycle, reduce the earthquake response of superstructure；The another kind of device for being to arrange power consumption by 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, reduces the destruction of geological process.Mesh
Front both subtract seismic isolation technology and achieve preferably application, but above two technology is act as with reducing horizontal earthquake
Purpose, therefore both technology be only applicable to those to vertically insensitive structure or the knot of vertical earthquake isolating need not be carried out
Structure, therefore above-mentioned technology only disclosure satisfy that the needs of horizontal seismic isolation, also there is larger defect and hidden danger.But all previous earthquake
Investigation and analysis afterwards have been found that impact of the vertical seismic action to structure and harm can not be ignored, in some cases, vertically
Shake effect even plays control action, and tradition subtracts seismic isolation technology and typically all carries out subtracting shock insulation for horizontal direction, is therefore discontented with
The demand of sufficient vertical earthquake isolating, even under certain conditions, this seismic isolation technology can also produce amplification to vertical seismic action,
Huge threat is brought to the earthquake safety of structure.
Content of the invention

It is that the three-dimensional shock isolation pedestal with arc track of the present utility model, including base plate, bottom arc up to above-mentioned purpose
Track, middle part supporting conversion equipment, outside steel case and top board, one end of the bottom arc track is connected with the base plate and edge
The longitudinal length of track is bent upwards, and the bottom arc track supports conversion equipment and outside steel case and institute by the middle part
Top board connection is stated, the outside steel case is floating to be placed on the base plate and be connected with the top board, and the middle part supports conversion equipment
Two ends be connected with the bottom arc track and top board respectively.
The above-mentioned three-dimensional shock isolation pedestal with arc track, its three-dimensional shock insulation principle is using arc track extending structure
With equipment and the vertical natural vibration period of cultural relics in the collection of cultural institution, avoid the predominant period of geological process, reduce geological process；Using curved track
The level natural vibration period of road extending structure and equipment and cultural relics in the collection of cultural institution, the predominant period of geological process is avoided, reduces geological process,
Achieve in the horizontal and vertical direction while the purpose of shock insulation.
Preferably, described bottom arc track is evenly arranged in two orthogonal horizontal directions, according to structure
The curvature different with the selection natural vibration period of equipment and cultural relics in the collection of cultural institution, to extend the natural vibration period of above-mentioned object.
Preferably, described middle part supporting conversion equipment includes basal sliding axle, oblique guide rod, top slide axle and top
Otic placode, the basal sliding axle are built in arc track and are connected with oblique guide rod, and the oblique guide rod passes through outside steel case
And be connected with top otic placode by top slide axle, the top board otic placode is fixedly connected with top board.
Preferably, the reserved peace turn hole of the outside surrounding of the outside steel case is passed through so as to oblique guide rod, and ensure that tiltedly
Freely rotating to guide rod.
Preferably, the bottom arc track arranges eight, each horizontally arranged four.
Preferably, the supporting conversion equipment is respectively provided with eight, horizontally arranged four at each.
Compared with prior art, had the advantage that using the utility model of above-mentioned technical proposal：This practicality is new
Type solves the problems, such as to realize to realize vertical earthquake isolating while horizontal seismic isolation, reached to must realize level to and vertical earthquake isolating
Structure and equipment and cultural relics in the collection of cultural institution the purpose of three-dimensional shock insulation protection is provided, to greatest extent by geological process to protected knot
The bang path " cut-out " of structure and equipment and cultural relics in the collection of cultural institution weakens, extend protected structure and equipment and cultural relics in the collection of cultural institution from
Shake the cycle, avoid the predominant period of geological process, geological process is reduced so as to protection structure and equipment and cultural relics in the collection of cultural institution
Purpose.
