Description
Technical field
A kind of shock isolating pedestal is the utility model is related to, particularly a kind of building frustum shock isolating pedestal, belongs to architectural vibration-insulation
Cushion technique field.
Background technology
Shock isolating pedestal is that a kind of shock insulation that subtracts for building structure bottom developed in the last few years (shakes) technology, is characterized in
Effectively cut-off horizontal earthquake action power be transferred to superstructure through basis, with this reduce superstructure horizontal vibration thus it is effective
Protect superstructure.At present Civil Structrual Isolation art is more ripe, widely used shock insulation original paper is common
Laminated rubber bases and lead rubber bearing.Although existing laminated rubber bases have higher vertical bearing capacity, water
Put down to shearing variation rigidity and the advantages that good endurance, but there is also some shortcomings, particularly meet with shake strongly when, structure
Reaction can significantly increase, and especially when seismic energy concentrates on low-frequency range, the reaction of structure can be bigger.Now, due to every
It is small 100 times to shake the ratio of rigidity superstructure interlayer rigidity of the Seismic Isolation of Isolation Layer of bearing, it is even more small, deform main will be concentrated in every
Shake layer.Due to economic considerations, the diameter of shock isolating pedestal can not be usable too big, and its horizontal displacement is possible to exceed it
Deformation limit, so as to cause unstable phenomenon.It is existing《Seismic design provision in building code》In to prevent rubber support larger
Under horizontal shear deformation, cut and press load-bearing effective area too small and lose bearing capacity or regional area generation tensile failure,
Define effective diameter and 300% smaller value that the deformation of bearing horizontal shear not should be greater than 0.55 times of rubber support.It is existing in addition
Have that the tensile strength of normal stack rubber support and lead rubber bearing is relatively low, the 10% of insufficient compression strength, thus it is existing
《Seismic design provision in building code》In be proposed with the base isolation structure depth-width ratios of laminated rubber bases and be not preferably greater than 4, prevent side
Tensile failure occurs for edge bearing.The above-mentioned deficiency of normal stack rubber support becomes its master in Civil Structrual Isolation application
Want obstacle.
Utility model content
In order to overcome the drawbacks described above of prior art, the application relate to a kind of building frustum shock isolating pedestal, for solving
Be easily damaged under certainly existing shock isolating pedestal large deformation, bearing capacity not enough and major diameter bearing cost it is high the problem of.

A kind of building frustum shock isolating pedestal, it is characterised in that：The building frustum shock isolating pedestal is to be connected by multilayer
Plate and multilayer laminated steel rubber abutments stack the frustum structure formed, and multilayer connecting plate includes top layer connecting plate, bottom connects
Fishplate bar and multiple intermediate layer connecting plates between top layer connecting plate and bottom connecting plate；The top layer connecting plate and top
Building bottom plate is connected, and the bottom connecting plate is connected with basis；Wherein, it is provided between upper and lower two layers each connecting plate more
Individual laminated steel plate rubber support, size becomes big to multilayer connecting plate successively from top to bottom, every layer of the multiple laminated steel plate rubber
Bearing is uniformly distributed in upper and lower two layers of connecting plate periphery, and with upper and lower two layers of connecting plate bolt connection；Every layer sets from top to bottom
The quantity for the multiple laminated steel plate rubber supports put is 4N, and wherein N is the number of plies of laminated steel plate rubber support from top to bottom；It is described
Intermediate layer connecting plate center is provided with a circular hole, and a damper passes vertically through all circular holes, and its both ends connects with top layer respectively
Fishplate bar and bottom connecting plate are hinged.
Further, the multilayer connecting plate is circular or square.
Further, the laminated steel plate rubber support is the laminated steel plate rubber support of Intermediate Gray lead for retractable pencil.
Further, the multilayer connecting plate number of plies is 4 layers, and the laminated steel plate rubber support number of plies is 3 layers.
Further, the first layer lamination steel rubber abutments quantity is 4, second layer laminated steel plate rubber support number
Measure as 8, third layer laminated steel plate rubber support quantity is 12, is arranged at respectively into radiation symmetric with multilayer connecting plate center
Individual multilayer connecting plate periphery.
Further, the diameter of each layer laminated steel plate rubber support is identical or different.
Further, the damper is lead damper or viscous damper.
Following beneficial effect is achieved using marmem position limitation protection shock isolating pedestal of the present utility model：
Building frustum shock isolating pedestal of the present utility model, the frustum shape of its bearing itself provides for bearing to be arrived from above
The rigidity of lower change and damping, its rigidity and damping increase step by step from upper strata to lower floor, Stability Analysis of Structures.In addition, the utility model
Larger vertical bearing capacity can be provided for superstructure by using the less rubber support of diameter, meanwhile, it is capable to larger
Under geological process, the further increase of bearing horizontal displacement is further limited, it is therefore prevented that the possibility of unstability occurs for minor diameter bearing
Property, while the horizontally and vertically seismic energy that can also effectively dissipate, overcome the economy and minor diameter of major diameter bearing
The defects of bearing easy unstability.The different numbers of plies and height can be designed according to the design needs by changing bearing, be convenient for changing and adjusted, have
Extensive market prospects, energy-conservation, low cost.
