Description
Technical field
The utility model is a kind of bearing that is used for the large-span structure multi-dimension isolation damping, belongs to the technical field of building structure aseismatic load control device.
Background technology
Seismic forces and the wind power of shaking are the major control loads that building structure is born, and also are to cause building structure that the principal element of destroying and collapsing takes place.Large-span structure is generally landmark building and importance building; the quality of its anti-seismic performance is directly connected to the safety of huge people's life and national economy property; the response of cognitive structure under geological process exactly, and it is extremely important that it is implemented reliable antidetonation safeguard measure.Structural vibration control is a kind of novel antidetonation mode, promptly bears earthquake (wind shakes) effect jointly by control structure and structure, stores and consume earthquake (wind shakes) energy jointly, with the reaction of coordinating and alleviating structure.At present at the earthquake isolating equipment of earthquake developmental research only play level to function of shock insulation, but can not play level and the vertical effect of isolating simultaneously; Existing earthquake isolating equipment anti-pulling ability simultaneously, under strong external drive, draw easily bad, the shortage safeguard measure.A large amount of actual earthquakes show: for the vertical earthquake of large-span structure (wind suction) is a very important external drive.
Summary of the invention
Technical problem: the purpose of this utility model is the large-span structure multi-dimension isolation shock-damping rack of a kind of cheap, dependable performance of exploitation, easy construction; this bearing simultaneously level of isolation to vertical earthquake; the limit function that has horizontal direction simultaneously; vibrational energy also can dissipate when isolating earthquake; it is bad to protect earthquake isolating equipment not drawn under big external drive, can isolate or consume local vibration moment of flexure and node vibration moment of flexure.
Technical scheme: large-span structure multi-dimension isolation shock-damping rack of the present utility model is made up of energy dissipating support upper steel plate, sliding steel plate, energy dissipating support core pad, vertical damping device, pre-embedded bolt, energy dissipating support lower steel plate and the spacing steel plate of level; The energy dissipating support upper steel plate is shelved on the energy dissipating support core pad, and the energy dissipating support core pad is shelved on the energy dissipating support lower steel plate; The vertical damping device has two, corresponding respectively between both sides, energy dissipating support upper steel plate and the energy dissipating support lower steel plate of energy dissipating support core pad, the damping steel plate upper end at vertical damping device middle part is affixed with sliding steel plate, the lower end of vertical damping device and energy dissipating support lower steel plate are affixed, and sliding steel plate can slide in the conduit of energy dissipating support upper steel plate; The slip of this bearing in the main span direction limited in the corresponding respectively both sides in addition that are positioned at the energy dissipating support core pad of the spacing steel plate of level.The energy dissipating support core pad is viscoplasticity bearing or lead for retractable pencil viscoplasticity bearing or neoprene bearing or lead core rubber support.The vertical damping device is viscoelastic damper or viscous fluid damper or metal damper or frcition damper or intelligent damper.
When external drive cause level to distortion the time, for the main span direction, energy dissipating support and vertical damping device in level to deforming, the vibrational energy of the input that dissipates, the two ends of vertical damping device are provided with spacing steel plate, can play the limit function of horizontal direction; For the short direction of striding, because of the middle steel plate of vertical damping device has certain space between the conduit of upper steel plate, so the distortion of striding direction, dissipates vibration energy also can take place to lack energy dissipating support; When external drive causes vertical distortion, for downward motion, the energy that produces crimp dissipation fraction that compresses by bearing power consumption material layer, for the motion that makes progress, energy dissipating support upper steel plate and energy dissipating support core pad break away from, this moment, the vertical damping device produced distortion, the dissipates vibration energy, thus formed a vertical shock absorption system; No matter be for level to or vertical, energy dissipating support all is equivalent to the weak floor of a low rigidity high damping, effectively level of isolation to or the transmission of vertical motion energy, thereby play effectively level to vertical function of shock insulation; Because energy dissipating support upper steel plate and energy dissipating support core pad are freely shelved, pulling force can not pass to energy dissipating support, thereby has protected energy dissipating support to avoid being drawn bad possibility, has changed traditional bearing and has easily been drawn bad characteristics.When bearing vibration overturning moment and node vibration moment of flexure, the vertical damping device deforms, and energy dissipating support is played a protective role, in order to avoid that the tension side of energy dissipating support is drawn is bad.
This shows, this bearing can not only play level to shock insulation, and can play vertical earthquake isolating; Can not only shock insulation and can consume energy; Can protect energy dissipating support to avoid drawing bad; Can reduce to vibrate the damage effect of overturning moment or node vibration moment of flexure.
Beneficial effect: large-span structure multi-dimension isolation shock-damping rack of the present utility model has simple structure, the advantage effective, cheap, easy construction that consumes energy, and it can not only play level to shock insulation, and can play vertical earthquake isolating; Can not only shock insulation, and can consume energy; It is bad to protect earthquake isolating equipment not drawn under big external drive, can isolate or consume vibration overturning moment, local vibration moment of flexure and node vibration moment of flexure.
