Description
Technical field
The utility model belongs to Civil Structrual Isolation, energy-dissipating and shock-absorbing field, is specifically related to a kind of marmem tension rubber earthquake isolation support with horizontal seismic isolation, energy-dissipating and shock-absorbing, vertical resistance to tension.
Background technology
, widely used shock insulation original paper comparatively ripe in Civil Structrual Isolation art is normal stack neoprene bearing and lead rubber bearing at present.Although existing laminated rubber bases has higher vertical bearing capacity, horizontal direction is sheared advantages such as becoming rigidity and good endurance, but because the damping force of bearing own is little, energy dissipation capacity is low, the seismic energy that can not dissipate fast and effectively, need to be used in combination just and can obtain good shock insulation, damping effect with other original papers that consumes energy.In existing < < seismic design provision in building code > > for to prevent that neoprene bearing is under larger horizontal shear deformation, cut and press load-bearing effective area too small and lose supporting capacity or regional area produces tensile failure, stipulated that the distortion of bearing horizontal shear should not be greater than the effective diameter of 0.55 times of neoprene bearing and 300% smaller value.The tensile strength of existing normal stack neoprene bearing and lead rubber bearing is lower in addition, 10% of not enough compressive strength, therefore in existing < < seismic design provision in building code > >, suggestion adopts the base isolation structure depth-width ratio of laminated rubber bases should not be greater than 4, prevents edge bearing generation tensile failure.The above-mentioned deficiency of normal stack neoprene bearing becomes its major obstacle in Civil Structrual Isolation application.
Marmem (Shape Memory Alloy, SMA) the hyperelastic fatigue behaviour of material phase transformation is fine, and damage generally all inevitably will appear in common material in loading and unloading circulation, affects the life-span; Under normal temperature state, the recoverable strain of shape memory alloy material can reach 6%～8%, and ultimate tensile strength can reach more than 14%; Because the rigidity of shape memory alloy material austenitic state is greater than the rigidity of martensitic state, the modulus of elasticity of SMA will increase (ordinary metallic material is just the opposite) along with the rising of temperature, this just can make material at higher temperature, still keep high elastic modulus.
At present super-elasticity, damping characteristic and the shape memory effect based on marmem developed for a little less than quasi-complement normal stack neoprene bearing resistance to tension, prevent that the excessive device of shear strain from mainly having the following disadvantages: 1. marmem is arranged in bearing periphery diagonal cross, when the shear strain of bearing occurred level, must have (bundle) shape-memory alloy wire is pressurized, can not effectively utilize super-elasticity tensile property and the energy-dissipating property of marmem; 2. the angle of the shape-memory alloy wire of bearing periphery or tow and upper and lower junction plate is too small, can not provide effectively vertical stretching resistance for bearing; 3. the marmem of bearing periphery enters strong tension state too early, has obviously increased the early stage rigidity of shock isolating pedestal, affects the isolating affection of shock isolating pedestal.Therefore, be necessary very much to develop both not obvious raising bearing horizontal rigidities, can improve again the earthquake isolating equipment of marmem utilization rate and bearing tensile strength.
Summary of the invention
The purpose of this utility model is in order to solve marmem in prior art-rubber combined bearing resistance to tension deficiency and marmem utilization rate technical problem on the low side, propose a kind of both not obvious raising bearing horizontal rigidity, can improve again the earthquake isolating equipment of marmem utilization rate and bearing resistance to tension.
In order to solve above technical problem, the utility model is achieved by the following technical programs.
A kind of marmem tension rubber earthquake isolation support, it includes upper junction plate, lower connecting plate, by connecting bolt, be connected in the laminated rubber bases between upper junction plate and lower connecting plate, symmetry is laid in the SMA Tendons of neoprene bearing surrounding, it is characterized in that: the four edges line middle part of described upper junction plate and lower connecting plate is all connected with directive wheel, four bights at upper junction plate and lower connecting plate are provided with the clam member with curved slot for solid shape memorial alloy drag-line, described SMA Tendons is " V " shape and falls " V " shape layout in four sides of laminated rubber bases.Its beneficial effect is to make shock isolating pedestal under the prerequisite of not obvious increase horizontal rigidity, the ability with higher resistance to tension and dissipates vibration energy, and make all SMA Tendons when there is various distortion in shock isolating pedestal all in extended state, increase operation rate.
Above-mentioned directive wheel comprise for through the fixed pulley of SMA Tendons, play as steering spindle that fixed pulley turns to, the fixing steering column jacket of steering spindle.Its beneficial effect is that every strip memorial alloy drag-line internal stress is evenly distributed, for upper junction plate and lower connecting plate provide pulling force, the distortion of guiding SMA Tendons, to adapt to various shear strain and the stretcher strain of marmem tension rubber earthquake isolation support.
The above-mentioned clam member for solid shape memorial alloy drag-line is comprised of two curved slots that are arranged symmetrically with and fastening bolt holes, and each clam member can be fixed two strip memorial alloy drag-lines simultaneously.Its beneficial effect is in relatively little scope, has increased contact length and the contact area of SMA Tendons and clam member, for SMA Tendons provides more effectively locking power.
Above-mentioned SMA Tendons can be shape memory alloy twisted wire, can be also shape-memory alloy wire bundle.Its beneficial effect is, compares and has higher safety reliability with single major diameter shape-memory alloy wire, even certain one or a few shape-memory alloy wire ruptures in drag-line, also can not affect the allomeric function of drag-line.
