Description
Technical Field
The invention relates to the technical field of seismic isolation and reduction, in particular to a swinging type seismic isolation support.
Background
The earthquake causes serious damage to various building structures and equipment, and the whole society of the earthquake area is paralyzed. The seismic isolation technology achieves the effect of reducing the seismic response of a structure or equipment by reducing the input seismic energy of the structure. The essential role of shock insulation is to separate structures or components from seismic ground motion or support motion which may cause damage, to isolate the propagation path of seismic energy, and to reduce the seismic force and energy input into the superstructure, thereby reducing the seismic response of the superstructure and achieving the desired fortification requirements. The separation or decoupling is realized by arranging a shock insulation layer at a specific part of an engineering structure and arranging a shock isolator, a damper or other auxiliary devices so as to prolong the natural vibration period of the whole structure system and increase the structural damping, thereby reasonably controlling the dynamic reaction (acceleration, speed and displacement) of the structure under the action of an earthquake and ensuring the safety and normal use environment of the structure and people, instruments, equipment, decoration and the like in the structure.
According to the difference of energy dissipation and shock absorption principles, the shock insulation types comprise laminated rubber support shock insulation, lead core rubber support shock insulation, ball (or roller) shock insulation, suspension foundation shock insulation, friction pendulum support shock insulation, sliding support shock insulation and the like, wherein the rubber support shock insulation technology is the most widely applied and technically mature one in the shock insulation technology and comprises a laminated rubber support, a lead core rubber support and a high-damping rubber support. The laminated rubber support is formed by alternately laminating steel plates and rubber, the rubber has the characteristics of low elasticity and large deformability, and the steel plates have high elasticity and small deformability. When using both cooperations, when the vertical pressurized of support, radial deformation all takes place for steel sheet and rubber, nevertheless because the deformation of steel sheet is less, it will retrain the deformation of rubber to make rubber be in the three-dimensional pressurized state, vertical bearing capacity improves, in addition the vertical bearing capacity that steel sheet itself has, therefore the support has higher vertical bearing capacity, and vertical compression is less. On the other hand, when the support is subjected to horizontal action, the steel plate cannot restrain the shearing deformation of the rubber, the shearing deformation of the support is approximately the superposition of the horizontal deformation of each rubber sheet, and therefore the horizontal deformation of the support is large. In addition, the rubber support can also provide proper restoring force of the vibration isolator during large earthquake displacement. However, because the rubber and the steel plate basically have no energy consumption capacity, the damping of the laminated rubber support is small, the horizontal restoring force model is similar to a straight line, and the laminated rubber support must be matched with a damper in a shock isolation system for use, and a simple, convenient and effective method is to insert a lead core capable of consuming energy through plastic deformation into a circular hole in the middle of the laminated rubber support to form the lead core rubber support. The lead rubber bearing can provide horizontal flexibility and restoring force while supporting a structure vertically, and can provide required hysteretic damping, so that the lead rubber bearing is widely applied to the shock insulation of bridges and houses. Compared with a laminated rubber support, the restoring force model of the lead core rubber support can be similar to a double-line type model, and the lead core rubber support has good hysteretic energy dissipation capacity. The other rubber support with energy consumption capability is a high-damping laminated rubber support, and a certain amount of graphite is doped in a common rubber material, so that the rubber has good damping performance. The high-damping laminated rubber support adjusts the damping size by controlling the graphite addition amount, and the restoring force model is approximate to a shuttle shape and has good energy consumption capability. The rubber support shock insulation technology has the characteristics of clear shock absorption mechanism, obvious shock absorption effect, convenience in construction and installation and the like, the shock insulation support in the prior art provides self-restoring force through elasticity of materials such as rubber after deformation, damping is small, a horizontal restoring force model is similar to a straight line, and the shock insulation support must be matched with a damper to be used in a shock insulation system.
Therefore, it is necessary to provide a rocking-type seismic isolation bearing to solve the above-mentioned technical problems.
