Abstract

The multiple-dimensional shock insulating and reducing plant for civil engineering consists of screw bolt, precompressed spring, attached steel plate, upper steel plate of energy dissipating seat, vertical damper, energy dissipating seat, high-strength anchorage cables and lower steel plate of energy dissipating seat. The attached steel plate is fixed to the upper steel plate of energy dissipating seat via screw bolt, the precompressed spring is set between the attached steel plate and the screw nut on the screw bolt, the vertical damper is connected between the attached steel plate and the lower steel plate of energy dissipating seat via the high-strength anchorage cables. The present invention has the advantages of simple structure, high energy dissipating effect, low cost and easy construction. It can separate both horizontal and vertical shock and dissipate shock energy without damage.

Description

The engineering structures multidimensional is every damping device
One, technical field
The present invention is a kind of device that is used for civil engineering structure antidetonation (shaking), and especially a kind of multidimensional is every damping device.
Two, background technology
Seismic forces and the wind power of shaking are the major control loads that building structure is born; also be to cause building structure that the principal element of destroying and collapsing takes place; force mechanism and the dynamic response of cognitive structure under the dynamic load effect exactly, and it is implemented reliable antidetonation (shaking) safeguard measure is the research topic of a frontier nature.Structural vibration control is a kind of novel antidetonation (shaking) mode, promptly utilizes isolator or damper to isolate or consumption external drive energy, alleviates the destruction of external drive to main structure to reach.At present the earthquake isolating equipment at the earthquake developmental research has rubber vibration isolation cushion, lead-rubber shock insulation pad and sliding and shock isolation device etc., at the energy-dissipating device of earthquake (wind shakes) developmental research viscoelastic damper, viscous fluid damper, metal damper, frcition damper, marmem damper, magnetic () rheological damper etc. is arranged.Yet these earthquake isolating equipments only play level to buffer action, but can not play level to the vertical effect of isolating simultaneously; And energy-dissipating device can not play function of shock insulation; Existing earthquake isolating equipment anti-pulling ability simultaneously, under strong external drive, draw easily bad, the shortage safeguard measure; Existing do not possess isolation or consume the local vibration moment of flexure and the effect of node vibration moment of flexure every damping device.A large amount of actual shake (shaking) evils show: for large-span structure, bridge construction and highrise building, vertical earthquake (wind suction) is a very important external drive, must give enough attention.
Three, summary of the invention
1, technical problem
The engineering structures multidimensional that the objective of the invention is to develop a kind of cheap, dependable performance, easy construction is every damping device; this device simultaneously level of isolation to vertical earthquake; 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.
2, technical scheme
Engineering structures multidimensional of the present invention is every damping device, it is characterized in that this device is made up of bolt, pre-compressed spring, additional steel plate, energy dissipating support upper steel plate, vertical damping device, energy dissipating support, high-strength anchor cable, energy dissipating support lower steel plate, additional steel plate and energy dissipating support upper steel plate are by bolt, between the nut on additional steel plate and the bolt, also be provided with pre-compressed spring, be connected with the vertical damping device between additional steel plate and energy dissipating support lower steel plate, two of vertical damping device is connected with the energy dissipating support lower steel plate with additional steel plate by high-strength anchor cable.Energy dissipating support 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 intelligent damper or metal damper or marmem damper or frcition damper.
When external drive cause level to distortion the time, energy dissipating support and vertical damping device in level to deforming, the vibrational energy that dissipates and import, simultaneously, energy dissipating support can level of isolation to vibrational energy from substructure to top structural transmission (perhaps superstructure is to the bottom structural transmission), can reduce the destruction of external drive significantly in view of the above to main structure; When external drive causes vertical distortion; during small deformation; by the energy that pine produces crimp dissipation fraction that compresses of bearing power consumption material layer; during large deformation; promptly when the up-throwing force of superstructure during; superstructure drives additional steel plate and moves upward; this moment, the vertical damping device produced distortion; the dissipates vibration energy; freely shelve owing to adding steel plate and energy dissipating support simultaneously; connect together by pre-compressed spring; allowed vertical distortion greater than the precompression sum of the gravity of superstructure and spring; thus formed a vertical earthquake isolating system, can isolate vertical vibrational energy from substructure to top structural transmission (perhaps superstructure is to the bottom structural transmission); Because additional steel plate and energy dissipating support are freely shelved, big 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 that this multidimensional can not only play level to shock insulation every damping device, 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.
3, beneficial effect
The engineering structures of being invented has the advantage of simple structure, effective, cheap, the easy construction of power consumption every damping device, 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.It can be widely used in the bearing of large-span structure, bridge construction and highrise building every damping or basic in damping.
