Description
Technical field
The utility model relates to a kind of novel superimposed shock isolating pedestal of minute surface slippage rubber, is applicable to existing building, new building thing, especially the seismic hardening of middle and primary schools' schoolhouse.
Background technology
After the earthquakes in Sichuan, each schoolhouse that State Council has issued national middle and primary schools carries out the file that antidetonation is identified and reinforced, and this is the requirements of epoch to us, is a kind of historic responsibility.Its time is short, workload is very huge, it is high to require, responsibility is heavy, and middle and primary schools reinforce and can only carry out during summer vacation, therefore, how to develop a kind of effectively, economical, reliable, speed of application is fast, existing building is destroyed little reinforcement means, has become very important responsibility of engineers and technicians and task.
Earthquake causes great injury and loss for people and building, traditional method is to rely on the strength and stiffness of structure self to resist earthquake, rely on the distortion and the damaged energy that imports building into that consumes of structural element, this method often can not be accomplished no collapsing with strong earthquake sometimes, the infringement of building in earthquake is huge often, has greatly surpassed society and owner's tolerance range.
Seismic isolation technology is that a kind of seismic energy that prevents imports the effective ways of building into, thereby has not only protected building better, reduces the infringement of building, and can effectively reduce even prevent casualties.Seismic isolation technology at present commonly used is in the bottom of building neoprene bearing to be set, but there is very big defective in this technology, and the service life of less stable and block rubber is long etc. under, the horizontal loads less such as the vertical rigidity of block rubber.Also have some other shock isolating pedestal, some its make comparatively complicatedly, cost is higher; Endurance issues such as some adopts the steel member, and is underground because of being in for a long time, and it is antirust are more difficult; Some adopts poly-tetrafluoro plate as the shock insulation material, its durability and be under the high pressure for a long time because of poly-tetrafluoro plate, adhesion problems between the two boards cannot say for sure do not have reliable evidence proof can not produce adhesion under this condition, even and have adhesion also can not bring serious harm by card.
Summary of the invention
