Description
Technical field
The utility model is a kind of construction measure of three-dimensional architectural vibration-insulation bearing, solves the vertical earthquake isolating problem that present common shock isolating pedestal can't effectively solve, and relates to a kind of compound three-dimensional shock isolation support.
Background technology
Shock isolating pedestal is a kind of energy-dissipating and shock-absorbing (shaking) technology that is used for the building structure bottom that developed in the last few years; be characterized in effectively cutting off horizontal earthquake action power and be passed to superstructure, reduce the horizontal vibration of superstructure thereby effectively protected superstructure with this through the basis.Existing product has the lead-rubber shock isolating pedestal, promptly by multi-layer thin steel plate and sheet rubber be superimposed through heat cure form and therein heart hole be pressed into lead rod.Existing miscellaneous shock isolating pedestal product is extensively in the shock insulation of many, the high-level structure of Ying Yu.Multi-dimensional earthquake (three translation freedoms and three rotary freedoms) though research obtained some breakthrough, be applied to put into practice less; The comparatively ripe at present theoretical level that is applied to actual engineering structures seismometer calculation and Analysis has reached three-dimensional (three translation freedoms), so particularly important at the shock insulation research of structure three-dimensional earthquake.Under the 3-D seismics effect, because the building structure vertical rigidity requires and the conflict of vertical earthquake isolating, the device that is used for vertical earthquake isolating at present is less, and the research of present stage, tests the earthquake shock insulation that is confined to two horizontal directions more.The utility model is constructed a kind of compound support that can be used in three-dimensional isolation on the basis of the horizontal shock isolating pedestal of tradition, be a kind of effective means that solves a structure vertical earthquake isolating difficult problem.
The utility model content
The utility model provides a kind of compact conformation and can reduce the compound three-dimensional shock isolation support of shock isolating pedestal height, raising isolating affection.
A kind of compound three-dimensional shock isolation support, comprise: horizontal shock isolating pedestal, on horizontal shock isolating pedestal, be provided with the vertical earthquake isolating device, described vertical earthquake isolating device comprises: pedestal, on pedestal, be provided with the horizontal lead extrusion damper of vertical lead extrusion damper and symmetric arrangement, and the position that is provided with of vertical lead extrusion damper is higher than horizontal lead extrusion damper; Described horizontal lead extrusion damper comprises the horizontal compartment that is located on the pedestal, is connected with the prominent axle of A type and is filled with damping material in compartment in horizontal slip on the compartment; Described vertical lead extrusion damper comprises the vertical compartment that is located on the pedestal, is vertically slidely connecting the prominent axle of Type B on the compartment and be filled with damping material in vertical compartment; Between prominent axle of A type and the prominent axle of Type B, be provided with kinematic link, and the two ends of kinematic link are rotationally connected with an end of the prominent axle of A type and an end of the prominent axle of Type B respectively; Coupling butterfly spring group with one heart on vertical lead extrusion damper is provided with upper connective plate and upper connective plate is connected with the other end of prominent of Type B in the butterfly spring group.
The tradition shock isolating pedestal only plays the effect of shock insulation in the horizontal direction, but it so its vertical rigidity is very big, can't isolate the vertical effect of earthquake to structure vertically because of the bearing structure deadweight.Convert vertical motion to horizontal vibration by the structure conversion equipment, and corresponding damped part is set, solve the difficult problem that traditional bearing can't vertical earthquake isolating with this.This principle of device is clear, and stable performance can be widely used in the three-dimensional isolation of structure.
Under the three dimensional earthquake load action, on the horizontal direction two effect components by on the bearing between lower linking plate level cut off the most of dynamic loading that transmits supreme structure on the horizontal direction to relative displacement with this.The butterfly spring group produces distortion because of vertical geological process, and one side is with the form storage area energy of elastic potential energy; On the other hand, studies show that the butterfly spring group also can consume certain energy by the friction of contact surface.The vertical energy-dissipating device of the three-dimensional shock isolation support that has at present only relies on butterfly spring group distortion power consumption, obviously its vertical energy dissipation capacity is relatively limited, and the utility model increases the relative motion power consumption of considering between the prominent axle of A type, the prominent axle of Type B and damping material on this basis and consumes part vertical motion energy.Kinematic link converts the vertical motion component of the prominent axle of Type B to the horizontal movement of the prominent axle of A type: on the one hand, between the vertical and damping material of the prominent axle of Type B back and forth relative motion can consume energy; On the other hand, the prominent axle of two A types level upwards with the reciprocal relative motion consumed energy of damping material.
The utility model provides a kind of simply constructed three-dimensional shock isolation support, by additional vertical on the horizontal shock isolating pedestal of tradition--and level conversion measure and additional damping device effectively solve an approach of the problem of present structure vertical earthquake isolating.Transform by vertical-horizontal movement connecting rod on the orthogonal direction, will vertically move back and forth and be converted to horizontal movement, have the characteristics of compact conformation, good stability: can effectively utilize level displacement increase energy-dissipating device repeatedly on the one hand; Adopt the energy-dissipating device of horizontal positioned can effectively reduce the overall height of shock isolating pedestal on the other hand, help improving the stability of bearing.This bearing can be widely used in three-dimensional isolation many, high building structure, and have good and economic.
