Inclined-plane guide type subtracts shock insulation Self-resetting bearing
Technical field
The utility model belongs to bearing technical field, more particularly to inclined-plane guide type subtracts shock insulation Self-resetting bearing.
Background technology
Present global earthquakes take place frequently, and are adopted extensively using vibration absorption and isolation support with buildings such as bridge, aqueduct, houses
With, subtract shock insulation displacement accordingly because vibration absorption and isolation support plays to subtract function of shock insulation and need, so vibration absorption and isolation support in earthquake centre all
It can be subjected to displacement or deform, can not all be resetted completely after these displacements or deformation shake so that building can not return to after shake
State before shake, the use of building, especially post-earthquake emergency response passage are had a strong impact on.Part-structure must be complete after requiring shake simultaneously
All reset could use, such as hydraulic engineering aqueduct, it is impossible to and reset completely, the antipriming failure of aqueduct junction can be caused, so as to
Lead to not water delivery, structural failure.The endless all reset of other buildings can also change the distribution of building internal force, or even surmount
Intrinsic controlled range, it is the normal service of building, and tackles next earthquake, brings very big influence.
The existing vibration absorption and isolation support for possessing runback bit function typically has following several:First, laminated rubber damping bearing,
Be using bearing material of main part rubber viscoelastic property, under action of horizontal seismic, occurred level deform when absorb and
Dissipation seismic energy, so as to reach the purpose for subtracting shock insulation.The shortcomings that aging and aged properties change being present greatly due to rubber, it makes
Approved with the life-span person of being not designed;Simultaneously also there is creep in rubber, and rubber support deforms for a long time, lead to not complete
Portion resets;Second, double curved surface support(Also it is friction pendulum support), it is a kind of using sphere swing principle, using gravity in sphere
The restoring force that provides of component realize and reset, it is maximum in maximum its restoring force of position of swing angle, zero swing angle position its
Restoring force is zero, and this phenomenon is that sphere swings intrinsic phenomenon, so as to cause double curved surface support close to zero swing position
Restoring force is less than frictional force, so as to realize complete Self-resetting;Double curved surface support is swung using sphere, and its hunting period is solid
Fixed cycle, when earthquake occurs, it is possible to can be overlapped with the seismic shock cycle, so as to amplify geological process, subtract shock insulation ability and pay no attention to
Think.Above two possesses the vibration absorption and isolation support of runback bit function when realizing damping, plane of its direction of displacement in horizontal displacement
Interior no constraint, it is possible to which occurring that displacement is excessive causes to fall beam.
