Description
Technical field
The invention belongs to building structure technology fields, are specifically related to a kind of high performance steel frame shock mount.
Background technique
Shock isolating pedestal is that developed in recent years a kind of subtracts shock insulation (vibration) technology for building structure bottom, its main feature is that
Effectively partition horizontal earthquake action power through basis is transferred to superstructure, with this reduce superstructure horizontal vibration thus it is effective
Protect superstructure.Existing product is mainly lead rubber laminated bearing.Oneself warp of existing miscellaneous shock isolating pedestal product is wide
General Ying Yu is more, in high-rise isolated.Though the research of multi-dimensional earthquake has obtained certain breakthroughs, be applied to practice compared with
It is few；Oneself reaches three-dimensional to the theoretical level applied to engineering structure seismometer point counting analysis more mature at present, therefore is directed to structure three
The shock insulation research for tieing up earthquake is particularly important.Under 3-D seismics effect, since building structure vertical rigidity requires and vertical earthquake isolating
Conflict, the device currently used for vertical earthquake isolating are less.
In order to improve the anti-seismic performance of structure, seismic isolation design is widely used.Subtract seismic isolation technology refer to by using
Seismic isolation device as far as possible separates structure with the taphrogeny that may cause destruction, reduces the earthquake for being transmitted to structure
Power and energy.In the prior art, this to separate the flexibility for generalling use increase system and offer damping appropriate to realize, it is former
Reason is to extend the natural vibration period of building structure by earthquake isolating equipment, increases the damping characteristic of structure, exists to reduce building structure
Acceleration response in earthquake, while seismic force can also be evenly dispersed in each structure, improve building structure itself
Shock resistance.Existing earthquake isolating equipment generallys use the lead core rubber support that cost is relatively low, manufacturing process is simple and performance is stable.
Lead core rubber support includes lead for retractable pencil stick, rubber layer and steel plate, and rubber layer and steel plate lamination adhesive, lead for retractable pencil stick are vertically embedded in rubber branch
In seat, lead core rubber support is fixedly connected down through connecting plate with bridge and bridge pier.
Mainly there are natural rubber support, lead-rubber branch using more laminated rubber bases type in Practical Project
Seat, high-damp rubber support.However, mechanical property of the country scholar such as New Zealand, Japan, China and U.S. to laminated rubber bases
Energy test result all shows that the anti-twisting property of laminated rubber bases is still very weak.Laminated rubber bases are applied to and above-mentioned are not advised
Then structure is still difficult to solve the problems, such as that superstructure is exceeded by twisting strain, and more it is a risk that the torsion of superstructure
Fatal damage will be caused on displacement transfer to the very weak rubber support of anti-twisting property itself to rubber support, aggravation, which reduces, to finish
The whole shock resistance and anti-twisting property of structure.To improve laminated rubber bases tension, the insufficient defect of anti-twisting property, reduce horizontal
With vertical external force fatigue damage caused by support, with high-performance, high stability, transmit the vibration between steel frame
The effect of frequency effective attenuation.
