Description
Technical field
The present invention relates to Building Base-isolated Technique field, more particularly to it is a kind of for base isolation building system
Rubber hose rolling shock isolating pedestal.
Background technology
Destruction is produced to building structure to resist earthquake, it is to carry out shock insulation to building structure to commonly use one of anti-shock methods, i.e.,
Shock isolating pedestal is set at the column foundation position of building structure Seismic Isolation of Isolation Layer, to reduce transmission of the earthquake motion to superstructure, reduction ground
Shake the dynamic action to superstructure.Rubber earthquake isolation support is commonly used in building structure shock insulation at present.Rubber earthquake isolation support is divided into
Rigid reinforcement plate rubber support and flexible reinforcing plate rubber support, using more for rigid reinforcement plate rubber support, wherein wrapping
Include normal stack rubber earthquake isolation support, lead rubber laminated bearing, high-damping rubber shock isolating pedestal.Normal stack rubber support by
Rubber is superimposed with steel plate and formed, and its light plate plays distortion to elastomeric material, improves rubber bodies vertical rigidity, so that
Shock isolating pedestal is reduced horizontal earthquake action, larger vertical load can be born again.Because the damping of natural rubber is limited, no
The good earthquake energy of energy, easily produces larger horizontal displacement, therefore add lead for retractable pencil in General Purpose Rubber shock isolating pedestal
Lead rubber laminated bearing is just constituted afterwards.Lead for retractable pencil preferably can be deformed with rubber, earthquake energy and limitation
The horizontal distortion of bearing.However, there is also unsatisfactory all many-sides, such as damping energy dissipation characteristic for lead rubber laminated bearing
Occurs reduction etc. to a certain degree over time.In order to solve the problem of lead rubber laminated bearing is present, people work out one
High-damping rubber shock isolating pedestal is planted, i.e., additive is added in natural rubber, to increase the high damping characteristic of bearing.For rigidity
Reinforcing plate rubber support, is that, using steel plate as material of putting more energy into, its cost is high and from great, therefore people work out flexible reinforcing plate
Rubber earthquake isolation support, i.e., replace steel plate to make laminated rubber damping bearing with fiberboard.
In building structure shock insulation, in addition to using fixed shock isolating pedestal, also sliding isolation method.Wherein method it
One, sliding material is filled in Seismic Isolation of Isolation Layer, such as low friction coefficient materials graphite, sand grains, talcum powder play level of isolation earthquake
Dynamic action.In addition with slide type shock isolating pedestal and friction-pendulum shock-insulation support.Slide type shock isolating pedestal belongs to pure Frictional Slipping
Shock isolation system, has the disadvantage that Seismic Isolation of Isolation Layer deformation is larger, and can not automatically reset, when seismic force is less than the maximum static friction of shock isolating pedestal
It can not carry out energy dissipating during power, and due to disconnecting above and below at bearing, be also easy to produce the destabilization problems that topple, need additional antidumping to arrange
Apply.Friction-pendulum shock-insulation device, using friction pendulum flooring earthquake isolating equipment the shock insulation cycle can by choose suitable radius of curvature come
It is determined that, the change with shock isolation system top quality is unrelated.But equally exist Seismic Isolation of Isolation Layer and deform larger shortcoming, be also easy to produce mistake of toppling
Steady problem.
To sum up, existing rubber earthquake isolation support and sliding isolation bearing can not have environmental protection, high-damping, good antidumping concurrently
Continue the characteristics such as the ability of shock insulation under ability, the deformation of limitation Seismic Isolation of Isolation Layer and automatically reset ability, small shake, it is impossible to meet well
