Effect control belongs to the technical field of building structure passive energy dissipation control, and in particular to a kind of integrated form tuning quality damps wall.
Background technology
With to civil engineering structure antivibration（Shake）It is required that raising, got over using the engineering structure of structural vibration control technology
Come more.More the most commonly used is passive control technologies therein at present, mainly include energy-eliminating shock-absorbing technology and tuning vibration damping skill
Two major class of art.
Tuned mass damper（Tuned Mass Damper, TMD）It is a kind of very effective tuning vibration absorber, energy
Enough response of the effective attenuation structure under the dynamic load functions such as geological process, wind load, have been widely used.It is attached to
A minor structure in main structure, is made of, the inertia generated by TMD system's relative motions mass block, spring, damping unit
Reaction of the power to main structure, the vibration of control structure.Some published tuned mass dampers, it usually needs in the structure
Additional huge mass block is concentrated, not only occupies certain building using space, and very big hold is caused to place floor
Load with load；Meanwhile because of the limitation of floor position and quality, vibration damping control frequency range is narrow, for widebands such as geological processes
The effectiveness in vibration suppression of drive load is smaller；The various devices of partially-tuned Tuned mass damper are exposed in working environment, performance easily by
Environment influences.
In recent years, by the advantages such as space, energy dissipation capacity that wall provided can be made full use of strong, damping wall is increasingly
Mostly occur in building construction vibration control design case, however, current published most of damping wall（Such as viscous damping wall
（Application number 201410262093.5）, viscoelastic damping wall（Application number 201310124804.8）, lead damping wall（Application number
201110130891.6）, magnetorheological intelligent damping wall（Patent No. ZL200420037740.4）Deng）It is former based on energy-eliminating shock-absorbing
The device of reason utilizes the rare report of damping wall for tuning vibration attenuation mechanism.Meanwhile this kind of device based on energy-eliminating shock-absorbing principle is often
It is required that after certain deformation occurs for agent structure（Such as the malformation under big shake effect）, preferable damping energy dissipation could be provided
Ability limits the application of damping wall to a certain extent.
Therefore, the advantages of fully considering tuned mass damper and damping wall develops a kind of space and saves, arranges spirit
Living, control bandwidth, the integrated form tuning quality damping wall that damping energy dissipation is stable, reliability is high have certain meaning.

Specific embodiment
It is below with reference to the accompanying drawings and in conjunction with the embodiments, next that the present invention will be described in detail.
With reference to shown in Fig. 1-Fig. 4, integrated form tuning quality damping wall including stent 1, damps cylinder barrel 2, adjusts mass block 3,
Spring 4, guide rod 5, guide rod 6, guide sleeve 7 and attaching nut 8 are placed with several damping cylinder barrels 2, institute in the stent 1
It states and the adjusting mass block 3, the spring 4, the guide rod 5, the damping mass block 6, the guiding is equipped in damping cylinder barrel 2
Set 7 and the attaching nut 8, the adjusting mass block 3 and the damping mass block 6 are all connect with the guide rod 5, the guide rod
5 both ends are cased with the spring 4, and the spring 4 is between the adjusting mass block 3 and the attaching nut 8, the connection
Nut 8 is connect with the guide sleeve 7.
Further, it is risen in the damping cylinder barrel 2 between the guide sleeve 7 full of viscous fluid 9, the guide sleeve 7
To guiding the guide rod 5 and closing the effect of the viscous fluid 9, inside and outside cylinder barrel is connected as a single entity by the attaching nut 8, matter
Smooth contact is kept between gauge block and the damping cylinder barrel 2, enables mass block free to slide.
Further, the stent 1 is made of upright bar 11, longitudinal cross bar 12, lateral cross bar 13 and diagonal brace 14, is adjusted in support
While humorous damping unit, form the support system of lattice, based on structure provide lateral rigidity, undertake the lateral lotus in part
It carries, the upright bar 11, longitudinal cross bar 12, the lateral cross bar 13 and the diagonal brace 14 use steel or aluminum alloy materials, institute
The multilayer skeleton system that upright bar 11, longitudinal cross bar 12 and the lateral cross bar 13 are formed is stated, for placing multiple tuning resistances
Buddhist nun's unit, and limit their movement；The diagonal brace 14 then forms the support system of lattice, the body with multilayer skeleton system
It ties up to while bear tuning damping unit gravity, can be effective against structure lateral load, improve the rigidity of structure.
Preferably, the damping cylinder barrel 2 is made of master cylinder 21, attached cylinder 22 and closing nut 23, on the damping mass block 6
Equipped with damping hole 61, it can damp guide rod by installing the variable cross-section of the damping hole 61 for the damping mass block 6, change
The 61 internal friction degree of damping hole changes the damping capacity that the modes such as 61 length of damping hole obtain different characteristics.
Further, the adjusting mass block 3 and the damping mass block 6 provide quality jointly, and the spring 4 provides just
Degree, inertia force cause the slip of the damping mass block 6 so that and viscous fluid 9 flows through damping hole 61 and generates required damping,
