Description
Technical field
The present invention relates to a kind of shock insulation laminated rubber bases, belong to structures isolation effect control and vibration control field, be mainly used in the base isolation of buildings such as house and bridge.
Background technique
The laminated rubber bases shock insulation is a kind of comparatively ripe engineering seismic isolation technology, pass through shock-proof device, building superstructure and foundation " isolation ", change the dynamic property of superstructure, can greatly alleviate the dynamic action of earthquake, thereby reach the damping effect of " defeating a force with a tenderness " superstructure.Laminated rubber bases is by rubber layer and the steel plate layering is superimposed forms through high temperature vulcanized bonding.When neoprene bearing bore vertical load, the lateral deformation of rubber layer suffered restraints, and made neoprene bearing have very big vertical bearing capacity and vertical rigidity.The successively superimposed tension bearing capacity that has improved bearing of rubber layer and steel plate.The main at present form of using has natural rubber laminated rubber bases, high damping laminated rubber bases, lead rubber bearing, interior bag damping body laminated rubber bases etc.The damping of laminated rubber bases be estimate laminated rubber bases in the horizontal shear deformation process because the inelastic deformation of neoprene bearing constouctional material or interior friction and the index of produce power dissipation capabilities.Laminated rubber bases is provided with the damping material of cylindrical body at the central position of neoprene bearing, can improve the damping ratio of the substantially horizontal of laminated rubber bases.Existing lead rubber bearing comprises upper and lower jointing plate, lead for retractable pencil, steel plate, rubber plate, protective layer as shown in Figure 2.The damping of the laminated rubber bases of prior art and stiffness parameters are in case just can't regulate in the course of the work after selected again, thereby limited the isolation property of laminated rubber damping bearing, make it be only applicable to short-period median low structure and rigid construction, not too suitable to high level and skyscraper.The fixing parameter limit of existing laminated rubber bases the laminated rubber bases application area, the development space of laminated rubber bases is restricted.
Electrorheological fluid be by nanometer to the outstanding turbidity current body that the dielectric particles of micro-meter scale, insulation carrier fluid and additive mix, be a kind of have wide application prospect intellectual material.It is adjustable continuously that electrorheological fluid has shear strength, and the required energy consumption of liquid-solid transformation is low, responds quick and reversible character.Electrorheological fluid is rendered as the fluid with certain viscosity in the normal state, and when electrorheological fluid was among the electric field of certain intensity, electrorheological fluid can be converted into a kind of state of similar solid in moment.Electrorheological fluid is applied in fields such as automotive industry, hydraulic industry, machine building industry, sensor technology, biomedicines.According to the research that the Wen Weijia of Hong Kong University of Science and Thchnology professor is done, the novel giant electro-rheological liquid of development can reach the yield strength more than the 100kPa under the electric field strength of 4kV/mm at present, can satisfy the needs of practical engineering application.
Summary of the invention
Isolation property and the Applicable scope of the present invention in order to improve laminated rubber bases based on traditional laminated rubber bases technology and emerging electro-rheological technology, proposes half active electric rheologic composite laminated rubber bases of a kind of horizontal damping and rigidity Adjustable real-time joint.
The invention provides a kind of electric rheologic composite laminated rubber bases, comprise and include jointing plate 8, following jointing plate 9, rubber plate 3, steel plate 4, protective layer 11, it is characterized in that, steel plate 4 successively is superimposed together with rubber plate 3, the hole is established at steel plate 4 middle parts, rubber plate 3 middle parts hollow out and are clitellum shape, and the internal diameter of rubber plate 3 forms the space greater than steel plate 4 middle aperture between each layer steel plate 4 and each layer rubber plate 3; The middle part of last jointing plate 8 is provided with the injection that liquid filling hole 12 is used for electrorheological fluid 2, and liquid filling hole 12 is communicated with the through hole 10 that the bearing middle part forms, and is sealed with sealing plug 1; Electrorheological fluid 2 is full of the space that above-mentioned steel plate 4 and rubber plate 3 surround; The edge of each layer steel plate 4 is drawn and is used for the lead-in wire 7 that is connected with the control apparatus that control signal is provided.
Voltage by control lead-in wire 7 can change the electric field strength between each layer steel plate, thereby changes the state of bearing internal electrical rheology liquid, makes the horizontal rigidity of bearing and damping change.
Shear strength can reach more than the 30kPa when electrorheological fluid of up-to-date development was 1kV/mm when electric field strength, in order to reduce requirement to control voltage, the interior thickness of steel plate 4 is slightly thicker than the thickness at edge, makes electrorheological fluid 2 can reach sufficiently high electric field strength at the control voltage of setting so that be in the thickness of the electrorheological fluid 2 of steel plate 4 and rubber plate 3 inside less than the thickness of rubber plate 3.
Be suppressed with the annular seal groove 6 of projection a little in each layer steel plate 4 and rubber plate 3 superimposed edges.The sealing groove makes the bonding of rubber plate and steel plate more tight, and improves the bearing capacity of neoprene bearing, avoids the leakage of electrorheological fluid.
Described electric rheologic composite laminated rubber bases, the cross-sectional circumference that wherein goes up the substantially horizontal of jointing plate 8, following jointing plate 9 intermediate portions is rectangle or circle.
The present invention has utilized the controllability of electrorheological fluid, and the electric field strength that changes between each layer steel plate can change the yield strength of electrorheological fluid, thereby changes the horizontal rigidity and the damping of electric rheologic composite laminated rubber bases.When the electric rheologic composite laminated rubber bases of the present invention's proposition applies control voltage according to certain half ACTIVE CONTROL rule, can provide than the better shock insulation ability of conventional laminated rubber bases, and can improve the Applicable scope of shock insulation control system.
Half of the electric rheologic composite laminated rubber bases that the present invention proposes initiatively becomes the inside that damping portion is positioned at rubber layer, thereby makes adjustable damper and multilayer rubber formation one, both can save the space, design, process and install also comparatively favourable.Simple in structure, stable performance, practical that the present invention has, the advantage that has wide range of applications is applicable to having any occasion that laminated rubber bases is suitable for now.
