Abstract
The utility model belongs to the technical field of spherical steel bearings, and particularly discloses a metal damping seismic mitigation and isolation bearing. According to the technical scheme, a vertical constant-strength hyperbolic cylindrical steel rod parallel to a lower baffle is fixed to the outer side of the lower baffle of a base plate, an upper fixing plate provided with a clamping groove at the lower end is arranged on the outer side of the an upper bearing plate, the top end of the constant-strength hyperbolic cylindrical steel rod is inserted into the clamping groove, and certain distance exists between the inner lateral side of the lower baffle and the outer lateral side of a base. When an earthquake occurs or a beam is impacted, a shearing pin mechanism is broken, the upper fixing plate and the base plate move relative to each other, stress of the constant-strength hyperbolic cylindrical steel rod is even, due to the fact that total cross-section yield occurs when the constant-strength hyperbolic cylindrical steel rod deforms, energy consumption is high, and therefore influence of the earthquake on a bridge structure can be mitigated or isolated when the earthquake occurs.
Description
Technical field
The utility model belongs to bridge pad technical field, relates in particular to a kind of metal damping vibration absorption and isolation support with high damping properties.
Background technology
At present, the antidetonation spherical bearing for bridge using is mainly the intensity opposing seismic forces by structure itself, once seismic forces exceeds designed output, can cause bridge pad stopping means to destroy and lose efficacy, now cause bridge construction to destroy, not only cause tremendous economic loss, but also may cause huge casualties.
Chinese Patent Application No. is that 200910075146.1 and 201120391261.2 patent application discloses respectively a kind of elastic-plastic beam dropping prevention spherical steel support seat and a kind of large rigidity vibration absorption and isolation support.The elastoplasticity post that wherein " elastic-plastic beam dropping prevention spherical steel support seat " adopts, structure " elastic-plastic beam dropping prevention spherical steel support seat " thus be mainly that the elastic-plastic deformation that produces elastoplasticity post in spacing direction plays damping and isolation effect, on direction of displacement, elastoplasticity post can move freely back and forth along flanging, but can not play, well subtracts function of shock insulation; " large rigidity vibration absorption and isolation support " is for a plurality of " X " structure that is fixed together of type veneer, can to a certain degree improve its rigidity, but plate-like shape has determined that the mechanical property differences such as rigidity of its all directions are very large, the most obvious in the direction of vertical panel face and the stiffness difference of parallel-plate face direction, can not well tackle the uncertainty of seismic direction, thereby affect damping and isolation effect; And multi-disc " X " structure of type veneer combination can exist because of each group multi-disc " X " mechanical properties such as integral rigidity of type veneer are subject between plate position difference compared with affecting performance greatly, and the bad control of product quality, thus the isolation property that subtracts of bearing integral body affected.Be that current the used shock insulation ball shaped steel bearing that subtracts exists after shake the large and lower defect of rigidity of displacement.

The specific embodiment
The structure of a kind of metal damping vibration absorption and isolation support the utility model being provided below in conjunction with accompanying drawing is described in further detail:
As Fig. 1, shown in Fig. 2 and Fig. 3, structure chart for a kind of metal damping vibration absorption and isolation support provided by the utility model, its structure comprises the upper bracket plate 3 for supporting bridge beam body, be fixed on the first plane stainless steel plate 4 and the first plane slide plate 5 of this upper bracket plate bottom, bottom is provided with the ball core 6 of sphere slide plate 7, its border of mating with this ball core arrange bulge loop 81 and by the B of shear pin mechanism and the relatively-stationary base 8 of base plate, for be fixedly connected with bridge pier and be provided with base plate 9 and be arranged at base 8 and the second plane slide plate 10 and the second plane stainless steel plate 11 of 9 of this this base plates, wherein base plate 9 bottom periphery are provided with lower baffle plate 91 and the annular wing limit 92 being structure as a whole with it, in the both sides of upper bracket plate 3, be provided with that be structure as a whole with it and the spacing overhead gage 31 corresponding with lower baffle plate 91, both sides overhead gage 31 forms the first slideways 12, with the base 8 of bulge loop 81, snaps in wherein, in the annular wing limit 92 that above-mentioned base plate 9 bottoms arrange, be provided with some upper draw-in grooves 93, and in the both sides of its corresponding upper bracket plate 3, be provided with bottom with the upper mounted plate 2 of lower bayonet slot 15 and form the second slideway 13, in above-mentioned upper lower bayonet slot, be fixed with the shape parallel and upright with lower baffle plate 91 equal strength hyperbolic column type rod iron 14 as shown in Figure 4.The edge of upper bracket plate 3 snaps in the second slideway 13.Like this, upper bracket plate 3 can move freely direction along bearing with respect to upper mounted plate 2 and base 8 and move around, but does not slide with respect to base with respect to the spacing direction upper bracket of bearing plate 3.Above-mentioned shear pin mechanism is arranged at base 8 and base plate 9 four jiaos.The lateral surface of the medial surface of lower baffle plate 91 and base 8 keeps at a certain distance away, under normal circumstances, when moving freely direction generation horizontal shear along bearing, upper bracket plate 3 slides along the first slideway with base 8 within the scope of normal design, when there is earthquake or the collision of beam body experience, upper bracket plate 2 moves along spacing direction, upper bracket plate 2 drives base 8 to move, now, shear pin mechanism fractures, upper bracket plate 2 and base plate 9 relatively move, equal strength hyperbolic column type rod iron 14 stress deformations, total cross-section surrender during due to 14 distortion of equal strength hyperbolic column type rod iron, power consumption power is strong, therefore, damping and isolation effect is obvious, can prevent because of earthquake, meeting with bridge in the situations such as shock comes off from bridge pier.And because insert in lower bayonet slot 15 on the top of equal strength hyperbolic column type rod iron 14, so the top of equal strength hyperbolic column type rod iron 14 can move up and down in lower bayonet slot 15.
In the structure of above-mentioned metal damping vibration absorption and isolation support,
---equal strength hyperbolic column type rod iron 14 is hyperbolic cylinder list rod, and like this, because surrender cross section is circular, all directions yield force is identical, can better adapt to the uncertain characteristic because of external force directions that produce such as earthquake, experience shocks;
---equal strength hyperbolic column type rod iron 14 is that rigidity further increases like this along four rows that arrange upper mounted plate below outside described lower blend stop.The number of every row's equal strength hyperbolic column type rod iron 14 is determined according to designing requirement;
As shown in Figure 5, at the B of shear pin mechanism, be positioned at base 8 and base plate 9 contact surface positions are provided with the shearing groove 16 along its periphery, at shear pin 1 radial outside cover, there is guide 17, guide 17 comprises guide 18 and lower guide 19, upper guide 18 is threaded with base 8, lower guide 19 is threaded with base plate 9, shear pin 1 closely cooperates with upper guide 18 and lower guide 19, after causing shear pin 1 to fracture when earthquake occurring or clash into bridge floor, can upper guide 18 and lower guide 19 be taken out through over-rotation, change shear pin 1 convenient.
Above-mentioned explanation be take one-way support and is illustrated as example, and the utility model also comprises fixed and two-way type bearing, for bilateral support, overhead gage 31 and base 8 can be kept at a certain distance away.
