Description

Hoop wire rope steel ball type composite damping bearing
Technical field
The utility model belongs to bridge, building construction, nuclear power station, mechanical engineering anti-seismic technology field, is specifically related to a kind of hoop wire rope steel ball type composite damping bearing.
Background technology
Earthquake is one of natural calamity taking place frequently, and for a long time, the mankind are " helpless " in face of this natural calamity.Earthquake cause the immediate cause of Loss of Life and property be building strenuous vibration, destroy and collapse.Since twentieth century, the structure control technology of the antidetonation of the mankind to building, energy dissipating, damping is constantly explored, successively utility model and created following corresponding product and technology.
Lead core rubber support: by shear strain absorption and the dissipation seismic energy of lead for retractable pencil and rubber.
Hydraulic pressure viscous damper: dissipate, absorb seismic energy by liquid or the mobile generation damping force of semi-solid viscous material in cylinder body.
Friction-type damping supporting seat: adopt two spheres of upper and lower different radii to form two sliding friction pairs with coordinating position, guarantee the normal rotation of bearing and slippage function, in the time that earthquake horizontal force exceedes threshold values, between support friction pair, overcome friction produces relative sliding, large radius sphere friction pair can produce larger horizontal relative displacement, be that horizontal rigidity is less, thereby the kinetic energy that earthquake is produced is converted to potential energy, after breakthrough threshold values, less horizontal rigidity has played " shock insulation " effect.Due to the existence of frictional resistance, play " damping " effect simultaneously, consumed a part of earthquake energy.
Subtract the effect of shock insulation although above-mentioned lead core rubber support and friction-type damping supporting seat can play hoop, horizontal rigidity is too low, and soft foundation or bridge pier are crossed when soft, and damping effect reduces, and even can add the seismic response of macrostructure.And hydraulic pressure viscous damper is a kind of bar type structure, there is directionality, to reducing axial geological process successful, but earthquake is unforeseen to the geological process direction of bridge in advance, thereby it be provided with certain blindness, common way be suitable bridge at bridge to direction across bridge, hydraulic damper being all installed, limited so to a certain extent its mechanical motion, reduced damping effect.
In addition, existing pulling force bearing is all to connect opposing pulling force by convex-concave direct or indirect between upper bracket plate and lower support plate substantially, its connected mode is rigidity, when pulling force enough large, the destruction of bearing is without any omen, need to change time, can only whole bearing replacement, cost is higher and the cycle is long.
Summary of the invention
The purpose of this utility model is exactly the deficiency existing in order to solve above-mentioned background technology, and a kind of hoop wire rope steel ball type composite damping bearing that can play to the earthquake of all directions energy-dissipating and shock-absorbing effect is provided.
The technical solution adopted in the utility model is: a kind of hoop wire rope steel ball type composite damping bearing, comprise upper bearing plate and lower support plate, between described upper bearing plate and lower support plate, be provided with ball-crown body, bearing weight body and damper, the spherical of described ball-crown body matches with the spherical concave surface of bearing weight body, between described ball-crown body and upper bearing plate and bearing weight body, all contact by tetrafluoro slide plate slides, described damper is steel-wire rope damper, described steel-wire rope damper is arranged in the periphery of described ball-crown body and described bearing weight body in the form of a ring, described steel-wire rope damper comprises wire rope and is separately fixed on described upper bearing plate, in lower support plate two cover rope clamp, described wire rope is fixed between described two cover rope clamps.
Further, the described wire rope circular spiral shape structure that many strand wire coilings form of serving as reasons, described wire rope is overall circulus or the circulus that is spliced into by multi-segmental.
Further, described rope clamp comprises two doughnut-shaped steel plates, described two doughnut-shaped steel plates are bolted, on relative two faces of described two doughnut-shaped steel plates, be respectively equipped with the semicircle orifice that can hold steel wire penetrating along circumference, on described two doughnut-shaped steel plates, the semicircle orifice of correspondence position fastens the rope clamp hole that forms fixing wire rope.
Further, described rope clamp is overall circulus or the circulus that is spliced into by multi-segmental.
Further, between the circulus that the described rope clamp that is spliced into circulus by multi-segmental is sealing or sections and sections, leave space.
Further, described ball-crown body is supported on the spherical concave surface of described bearing weight body.
Further, also comprise dust cover, the upper and lower two ends of described dust cover are connected with lower support plate with described upper bearing plate respectively.
The utility model can use as common ball shaped steel bearing, pulling force bearing and damping shock proof bearing simultaneously:
Contact surface between ball-crown body and bearing weight body is sphere, and contact by tetrafluoro slide plate, ball-crown body can rotate on the recessed surface of bearing weight body, when rotation, between ball-crown body and top beam body, produce a horizontal relative displacement by a small margin, this motion is subject to the limited constraint of steel-wire rope damper, so this bearing has common the ball shaped steel bearing load-bearing that need to possess and the function that can rotate, can work as common ball shaped steel bearing and use.
Because steel-wire rope damper is fixed by rope clamp and upper bearing plate, lower support plate respectively, in the time that bearing weight body is subject to pulling force, this pulling force can be born by steel-wire rope damper, and produces corresponding distortion, has obvious omen, structural safety is produced to early warning, destroy even if produce, only need to change corresponding wire rope member, needn't change whole bearing, maintenance and replacing are convenient, and cost is low.
Simultaneously due to upper bearing plate be fixed on beam at the bottom of, lower support plate is fixed on Dun Ding or platform top, under Earthquake Inertia Force Acting effect, no matter this power is from where, between pier, beam, will produce relative motion, be to produce relative motion between lower support plate and upper bearing plate, this relative motion is subject to the obstruction of steel-wire rope damper, and wire rope produces shear strain, absorption, dissipation seismic energy, realized the impedance to taphrogeny.
The utility model has the function of common ball shaped steel bearing, pulling force bearing and damper concurrently, can resist the Earthquake Inertia Force Acting from all directions in horizontal plane, play the effect of energy-dissipating and shock-absorbing, be applicable to all kinds of bridges, house architectural structure, nuclear power station structure etc., there is wide market prospects and good economic benefit.
