Description
Technical field
Civil engineering anti-seismic damper technical field is the utility model is related to, more particularly to a kind of spacing reset friction-type resistance
Buddhist nun's device.
Background technology
China is a multiple country of earthquake, and some areas are at plate boundary therefore frequently encounter violent earthquake, therefore
It is a very big challenge for civil engineering structure antidetonation.For Architectural Structure Design instantly, basic thinking
It is that " small shake is not fallen ", " middle shake can repair ", " no collapsing with strong earthquake " and two benches are set up defences, but actually always by firmly anti-theory
To increase the rigidity of building, intensity keeps stability, but finds weak point existing for this way in practice, therefore anti-
Shake thinking is gradually to all kinds of dampers, vibration isolating suspension, actively with partly actively mixing control development and in building structure damping
Face achieves good effect.
The exploitation of wherein damper has also had more development till now, according to its principle be divided into friction-type, viscosity,
Electromagnetic type and TMD and TLD etc..Wherein friction damper uses comes mainly by the mechanics of materials and physical attribute and construction
Carry out energy-dissipating and shock-absorbing, but can carry out multiple defence line carry out it is spacing reset and external manual control damper carry out shock-damping energy-dissipating
It is also fewer, thus need be improved and deepen.
The content of the invention
The shortcomings that in order to overcome above-mentioned prior art, the purpose of this utility model are to provide a kind of spacing reset friction-type
Damper, multiple defence line carry out spacing reset, increase the service life, reach multiple defence line damping.
In order to achieve the above object, the technical scheme that the utility model is taken is：
A kind of spacing reset friction damper, including upper and lower friction plate 1, the T fonts of upper and lower friction plate 1 and left and right sides are slided
Lever 2 coordinates, and inverted L shape is made in the upper and lower end of friction plate 1, and inside is left groove and protruded to place the T fonts of T shaped slidings bar 2
Part so that the two forms cavity space and can mutually slided；The inner side of the T shaped slidings bar 2 of left and right sides is connected with branch and held round
Bar 5, two support round bars 5 are Nian Jie in summit end consolidation with the SMA silks 6 of two mutual skewed crossing drawknots, two support round bars 5
Two cavitys in left and right will be divided between upper and lower friction plate 1, friction plate 1 and T shaped slidings bar 2 above and below the inside cavity of left and right two
Between place several balls 4, the outside of T shaped slidings bar 2 is connected with baffle plate 3, and the baffle plate 3 of both sides is stuck in building structure.
Described T shaped slidings bar 2 smears molybdenum disulfide friction material with the upper and lower contact portion of friction plate 1.
Described T shaped slidings bar 2 and the junction of support round bar 5 are provided with piezoelectric ceramics 7, support round bar 5 and rub up and down
The contact portion of wiping board 1 is provided with piezoelectric ceramics 7, is consumed energy by the deformation for changing current control piezoelectric ceramics 7.
The length of the described groove of friction plate up and down 1 determines according to the ultimate elongation tension of SMA silks 6.
The beneficial effects of the utility model are：
Reach the effect of spacing reset by SMA silks 6；Piezoelectric ceramics 7 is controlled to carry out by artificial active control electric current
Further spacing power consumption, the utility model multiple defence line carry out spacing reset, increase the service life, reach multiple defence line and subtract
Shake.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Make narration in detail to the utility model with reference to the accompanying drawings and examples.
Reference picture 1, a kind of spacing reset friction damper, including upper and lower friction plate 1, upper and lower friction plate 1 and left and right sides
T shaped slidings bar 2 coordinate, inverted L shape is made in the upper and lower end of friction plate 1, and groove is left to place the T of T shaped slidings bar 2 in inside
Font ledge so that the two forms cavity space and can mutually slided；The inner side connection of the T shaped slidings bar 2 of left and right sides
There is support round bar 5, for two support round bars 5 to play a part of bearing top vertical load load-bearing, two support round bars 5 and two
The SMA silks 6 of mutual skewed crossing drawknot consolidate in summit end to be bonded, and two support round bars 5 will be divided into a left side between upper and lower friction plate 1
Right two cavitys, several balls 4 are placed above and below the inside cavity of left and right two between friction plate 1 and T shaped slidings bar 2, with
So that T shaped slidings bar 2 is consumed energy when being slided in the upper and lower groove of friction plate 1 by ball 4, the outside of T shaped slidings bar 2 and baffle plate
3 connections, the baffle plate 3 of both sides are stuck in building structure.
Described T shaped slidings bar 2 smears molybdenum disulfide friction material with the upper and lower contact portion of friction plate 1.
Described T shaped slidings bar 2 and the junction of support round bar 5 are provided with piezoelectric ceramics 7, support round bar 5 and rub up and down
The contact portion of wiping board 1 is provided with piezoelectric ceramics 7, is consumed energy by the deformation for changing current control piezoelectric ceramics 7.
The length of the described groove of friction plate up and down 1 determines according to the ultimate elongation tension of SMA silks 6, with more preferable
Spacing power consumption simultaneously protects damper.
Operation principle of the present utility model is：
During earthquake, it is spacing to carry out that T shaped slidings bar 2 carries out frictional movement in the groove of upper and lower friction plate 1, and passes through
Ball 4 moves friction and consumed energy；T shaped slidings bar 2 drives support round bar 5 flexible and tensioning, drives two SMA silks indirectly
6 elongations are shunk, and by the high intensity of SMA silks and can recover reset property come being capable of further reduction level under geological process
The displacement in direction is simultaneously resetted；The input size of current of piezoelectric ceramics 7 is changed by external artificial action to control piezoelectric ceramics 7
Deformation so that the piezoelectric ceramics 7 of support round bar 5 acts on a upper and lower fastening force, increases friction plate 1 up and down and T words
Frictional force between type sliding bar 2 is to increase energy-dissipating and shock-absorbing；Left and right is arranged on the piezoelectric ceramics 7 of the end of T shaped slidings bar 2 simultaneously
Also deformation produces power to prevent the stretching or compression in a direction in the presence of electric current, further plays the effect of spacing damping
Fruit.
