Description
Technical field
The utility model relates to the plumbous combination of a kind of steel core and subtracts shock insulation rubber bearing, is specially adapted to adopt in the engineerings such as house, bridge at earthquake-prone region, to reduce the seismic response of structure.
Background technology
Earthquake has caused very heavy life and property loss to the mankind, this wherein civil engineering damage and collapse and accounted for a big chunk wherein.At present, the engineering bound pair has lasted more of a specified duration in structural seismic research, and research work is more deep, and research range is also relatively more comprehensive, but actual effect is not an ideal very, and the miserable scene of China's Wenchuan violent earthquake in 2008 is still come clearly into view.This just makes that global earthquake resistant engineering personnel begin existing earthquake resistant design code and seismic measures commonly used are introspected and improved, and subtracts earthquake isolating equipment, the shock resistance of enhancement engineering structure, protection the people's lives and property safety with what research and development made new advances.Subtract seismic isolation technology and also therefore become one of research focus of earthquake resistant engineering.
Subtract seismic isolation technology and comprise shock insulation and two kinds of technology of damping.Wherein shock insulation is to utilize vibration-isolating system, the agent structure of managing to stop seismic energy to enter earthquake isolating equipment being installed.Damping then is to utilize special cushioning members or device, makes it that rate is introduced into the plastic zone when macroseism, produces big damping, and a large amount of consumption enters the energy of agent structure.By selecting suitable earthquake isolating equipment and the installation site of subtracting, size that can control structure internal force and distributing.Domestic and international project antidetonation personnel have researched and developed the earthquake isolating equipment that subtracts of many types, as neoprene bearing, lead core rubber support, sliding friction type vibration absorption and isolation support, elastoplasticity damping power consumption steel damper, MR damper, oil damper and the plumbous combination of steel energy-dissipating device etc.Existing two or more being subtracted the shock isolation method applied in any combination, and use new material to improve the existing performance that subtracts earthquake isolating equipment, is the main direction that subtracts the earthquake isolating equipment research and development.
Lead core rubber support (pad) is that the New Zealand scholar was developed in 1975, and this bearing forms by insert lead for retractable pencil in common layering neoprene bearing, has made full use of lead for retractable pencil good mechanical characteristic, comprises lower yield shear force and higher initial shear rigidity.In addition, the dynamic test to lead core rubber support shows that lead core rubber support has good hysteretic characteristic.Therefore under geological process, lead core rubber support has not only utilized the damping energy dissipation of rubber in deformation process, and the surrender of lead for retractable pencil equally can the extending structure cycle, earthquake energy.Another advantage of lead core rubber support is that the bearing drag that produces under effects such as temperature, automobile braking force, creep of concrete is lower, is beneficial to the anti-seismic performance that guarantees bridge pier.
The earthquake resistant engineering personnel begin the plumbous combined material of steel is studied in recent years, and on the electro-hydraulic servo static/dynamic universal testing machine, this combined material has been carried out quiet dynamic characteristics test, experimental result shows that the plumbous combined material of steel can make the plumbous two kinds of material collaborative works of steel, fellowship earthquake power consumption.This bearing earthquake displacement is little simultaneously, damping big, power consumption is stable and manufacture craft is simple, can satisfy the shockproof requirements of some specific engineering structuress.Therefore, compare, adopt the neoprene bearing of the plumbous combination of steel core to have self significantly some characteristic, also reduced the content of noxious material lead simultaneously with conventional lead core rubber support.
The sandwich clad steel of existing neoprene bearing is generally the horizontal steel plate that polylith is parallel to each other, and each sandwich clad steel is separate, gets in touch by rubber between steel plate and the steel plate.Use for reference the layout thought of stirrup in the civil engineering structure, comprising two kinds of arrangements, i.e. rectangle hoop and screw type stirrup.Existing sandwich clad steel is arranged the same rectangle hoop wherein of principle: each rectangle hoop is separate, gets in touch by longitudinal reinforcement between stirrup and the stirrup.But the sandwich clad steel arrangement that does not have similar screw type stirrup to arrange so far as yet.Therefore, be necessary to use for reference the basic layout principle of screw type stirrup, adopt the screw type steel plate to replace horizontal sandwich clad steel in the conventional neoprene bearing,, have better overall and reseting performance so that all steel plates can collaborative work in the bearing.
China is current to be in the flourish stage that the building traffic engineering is built, it is again the multiple country of earthquake, country and market subtract seismic isolation technology for the practicality of engineering structures huge demand, therefore, in conjunction with the engineering structures seismic design and use actually, development reasonable price, the simple engineering structures vibration absorption and isolation support of manufacture craft remarkable in economical benefits, social effect are great.
