Description
Technical field
The invention belongs to civil engineering structure earthquake resistant control technical fields, and in particular to directly support two using type to efficient spatial
Secondary displacement equations damper device.
Background technology
The basic principle of engineering structure damping is to utilize special cushioning members or device, is allowed to take the lead under severe earthquake action
Into mecystasis, damping is generated, and then consumes the energy in input architectural structure system, mitigates the dynamic response of structure,
The safety for preferably ensureing main structure body is a kind of effective, safety, economic engineering cushion technique.Domestic and international technology people thus
Member has developed and has developed the damping device for having used many types.Increase with the span of fabric structure, the increase of height
And the increasingly complication of structure type, the engineering structure designed according to traditional design method is under severe earthquake action, it is difficult to keep away
Exempt to damage and destroy.Structural dynamic response caused by inhibiting external impetus load by vibration control technology is to improve structure peace
The effective means of full property, such as apply passive earthquake resistant control technology.Wherein, structure is carried out using various viscous dampers passively to resist
The technology for shaking control is more common.
The damping energy consumption of structure is that damper is added in building structure, to consume the seismic energy of input structure, to
Reduce the seismic response of structure.Because building structure does not allow generally that larger level displacement deformation occurs, played to be effective
The energy dissipating of damper acts on, and generally requires amplifying device to amplify the stratified deformation of building structure.Under normal circumstances, it equipment or builds
For building structure under external force, geological process or wind action, the relative displacement or corner generated between structure different component is smaller,
And existing displacement relationship type energy consumer is required for structure that there is larger relative displacement or corner can just give full play to energy consumption energy
Power, to affect the energy-dissipating and shock-absorbing effect of energy consumer, while existing energy-consuming device integrally occupies larger construction area, shadow
The service efficiency in the space of building structure is rung.And need complicated energy dissipation brace system, the support system rigidity of energy consumer
The energy consumption effect for influencing energy consumer again, also produces influence so that such energy-consuming device is in practical application to structure overall stiffness
In be restricted.
Displacement equations effect is not notable existing for damper device of the patent of the present invention for current building structure, and occupies
A series of problems and disadvantage of most wall area, it is proposed that a kind of novel efficient spatial is directly supportted secondary using type end
Displacement equations damper device.This damper device will produce the displacement of bigger, i.e., is completed to initial displacement by displacement equations bar
First time displacement equations, for the first time amplification displacement using duplex moving gear complete second of displacement equations, it will be apparent that carry
High enlarge-effect, avoids the drawbacks of damper can not give full play to damper in tiny displacement deforming at this stage.From
And substantially reduce injury of the effect of vibration to building structure.Damper device work simultaneously and operational efficiency are high, use the longevity
Life length, energy consumption effect is notable, and compared to the damper of cockermegs at this stage, this damper, which uses, to be arranged in wall end
Vertical type displacement mobile support, occupies less wall area, while having simple structure, and cost is considerable, easy for installation, operation side
Just, the features such as flexible arrangement, firm and durable, therefore there is wide development and application foreground.

Second displacement amplification damper device is directly supportted in type end, has and occupies less wall area, device is simple, can be used for generally pacifying
Dress, improves the problem of damper occupies entire metope, to which wall area more efficiently be utilized, although reducing work
Space, but whole antidetonation efficiency is improved, it has broad application prospects.
The present invention is mainly by vertical type displacement mobile support, displacement equations bar, duplex moving gear amplifying device, damper dress
Set what equal devices were constituted.The present invention, will be upper by being fixedly connected through bolt between vertical type displacement mobile support and upper floor beam
The relative displacement of layer is transmitted to displacement equations bar by vertical type displacement mobile support, amplifies by the first time of displacement equations bar and makees
With so that the small relative displacement of interlayer has obtained the amplification of first time, the position that displacement equations bar will be exaggerated for the first time again
It improves existing damper to realize secondary displacement equations moved through the further amplification for crossing duplex moving gear and exists
The inapparent disadvantage of amplification effect in small relative storey displacement, has carried out secondary displacement equations in total, and damper is made to generate more
Big relative displacement, and then damper generates the damping force of bigger, to reach more preferably damping effect.It is effective to improve building
Structural vibration control efficiency so that damper it is medium and small shake vibration under, can also give full play to the performance of damper.It is upright simultaneously
There is no the cockermegs as displacement type damper at this stage for formula displacement mobile support through entire metope, occupies prodigious
Wall area, the vertical type displacement mobile support of damper of the invention are mounted on the end of wall, occupy less area, to
More wall areas are reserved to complete wall windowing, wall decoration etc. is more pacified to reach more efficient spatial utilization rate
Full purpose.
Deficiency in for the above-mentioned prior art to solve above-mentioned technical problem, design efficient spatial are straight using type end
