Description
Technical field
The utility model relates to a kind of support systems, can be to the energy dissipating that damper displacement amplifies more particularly, to one kind
Support system.
Background technique
The most basic installation method of energy dissipation damper is at present: damper and bracing members or concrete wall are directly gone here and there
Connection.One end of damper is connect with the top of bracing members or concrete wall；The other end of damper and opposite floor are straight
It connects in succession, damper is horizontal positioned.The relative storey displacement that the displacement of energy dissipation damper is equal to floor subtracts bracing members or concrete walls
The deformation of body.In order to guarantee the displacement of damper, it is desirable that the rigidity of bracing members or concrete wall is sufficiently large.In the connection type
Under, the maximum displacement of damper is no more than the relative storey displacement of floor.Therefore when malformation very little, what damper played
With regard to very little, energy dissipation capacity is very poor for effect.So that its field used is mainly limited under geological process, floor Displacement Ratio is biggish
Structural system.
The Chinese patent of Patent No. 201420075418.4 discloses a kind of displacement amplification device for oil damper,
It is attached on oil damper.Oil damper is connect by amplifying device with bracing members.Device construction is complicated, reliability compared with
Difference.And the scale of construction is too small, can not undertake larger damping force, actually allows maximum displacement also very little.Therefore practical engineering application value
It is lower.
Utility model content
The purpose of this utility model be exactly in order to overcome above-mentioned existing energy-dissipating support there are the shortcomings that, and providing one kind can be right
The energy-dissipating support system that damper displacement amplifies.The utility model is the support with mechanical motion mechanism, can be to installation
The displacement of damper in the support amplifies.
The purpose of this utility model can be achieved through the following technical solutions:

Horizontal movement.By the leverage of swing arm, the ratio of passive arm and active arm lengths is exactly passive arm horizontal displacement and master
The ratio of swing arm horizontal displacement.It is passive by setting because the horizontal displacement of master arm depends on the relative storey displacement of floor
The lenth ratio of arm and master arm can control passive arm by the degree of floor displacement equations.Because damper is directly and passively
Arm connection, is also equivalent to artificially control the magnification level of damper displacement.
The utility model can according to the design needs, any increase multiple for setting damper displacement, therefore can be very big
The energy dissipation capacity of ground increase damper.
Compared with prior art, the utility model has the following advantages that and technical effect:
1, good economic benefit: because can damper displacement be amplified according to the design needs.It contributes onesize damping
Device, if displacement increases, energy dissipation capacity will also be increased substantially.It is such then in the premise for keeping identical damper always to consume energy
Under, so that it may reduce the usage quantity of damper.
2, the use scope of damper is expanded: the very big structural system of some horizontal anti-side rigidities, because making in earthquake
Floor under is displaced very little.Common energy-dissipating support is installed in this structural system, because of the displacement very little of damper, because
With regard to seldom, the efficiency of damping is just very low for the energy consumption of this damper.Therefore damper is also just not suitable for rigid used in this horizontal anti-side
Spend very big structural system.
After using this energy-dissipating support system for amplifying damper displacement of the utility model, although the interlayer position of floor
Very little is moved, but the displacement of damper is amplified, therefore the energy consumption of damper can be very big, the efficiency of damping naturally can
To greatly increase.Therefore, originally some horizontal anti-after using this energy-dissipating support system for amplifying damper displacement
The very big structural system of side rigidity, such as frame shear wall structure or shear wall structure etc. can be carried out using damper
Energy-dissipating and shock-absorbing.
It is some other it is extraneous influence, such as wind or ambient vibration etc., caused displacement structure may also very little, but
Perhaps noise, vibration etc. but influence very greatly the impression of people or working environment etc. to acceleration.To vibrations some in this way, commonly
Energy-dissipating support is difficult to play a role.And after using this energy-dissipating support system for amplifying damper displacement, some water of script
Prosposition moves the structural vibration of very little, and damper progress vibration damping also can be used and control.
3, simple structure, high reliablity, flexible arrangement: the utility model is on the basis of former common energy-dissipating support, mainly
It is to increase supporting pivot and swing arm, then without other complex components.Therefore machining accuracy and maintenance requirement be not high.Because of master
Wanting material is common iron, therefore its service life can be with the building structure same service life, if it find that problematic, and maintenance is also very
It is convenient.Damper in the utility model, according to the design needs, it can be arranged on floor, top plate beam can also be arranged in
Under.If be arranged under top plate beam, support two sides can open the door hole without influencing passage.It thus will be to because arranging energy-dissipating support
And the use of building is influenced, it is reduced to minimum.
