Description
Technical field
The utility model belongs to technical field of bridge more particularly to a kind of big displacement active type vibration absorption and isolation support.
Background technology
It is up to 80% or more, while Long span continuous bridge, suspension cable in the length ratio of the circuit Bridge of geological state complexity
The design of the bridges such as bridge, curved bridge causes bridge temperature variable displacement increasing.In order to meet the requirement of bridge beam body big displacement,
Big displacement bearing used at present is to use to modify to the upper base plate of common bearing, and corresponding size is done to it and is carried out
Increase.But it is higher that the bearing that i.e. this structure does not change not only designs then relatively large sized, cost, and its subtract every
The performance of shake function also is difficult to meet.
Utility model content
The utility model aim be just to provide it is a kind of it is simple in structure, disclosure satisfy that Long span continuous bridge, suspension bridge, curved bridge
Equal bridges are because of the increasing big displacement active type vibration absorption and isolation support of bridge temperature variable displacement.
To achieve the above object, technical solution used by the utility model is：
A kind of big displacement active type vibration absorption and isolation support, structure include constituting the upper bracket plate and undersetting of support body
Plate, it is characterised in that：It is provided with and can be fixed with bridge beam body or bridge pier at the top of the upper bracket plate or lower support plate
Big displacement sliding panel, and be provided with sliding friction between the big displacement sliding panel and the upper bracket plate or lower support plate
It is secondary；Limited position mechanism is set on constituting the big displacement sliding panel medial surface.
The additional technical feature for constituting a kind of above-mentioned big displacement active type vibration absorption and isolation support further includes：
--- it is wear-resisting four be fixed in the upper bracket plate or lower support plate plate face to constitute the sliding friction pair
Fluorine plate and the stainless steel plate being fixed on the big displacement sliding panel medial surface are constituted；
--- it is to be set to the symmetrical both ends of the big displacement sliding panel medial surface or border to constitute the position-limit mechanism
Block constitute；
--- being provided between the upper bracket plate and lower support plate for constituting the support body makes the two is relatively-stationary to cut
Power pin or shear studs component.
A kind of big displacement active type vibration absorption and isolation support provided by the utility model has following excellent compared with prior art
Point：First, being made of big displacement sliding panel and vibration absorption and isolation support body assembly since the bearing obtains structure, it is provided with cunning between the two
Dynamic friction pair, therefore the big displacement sliding panel can be used to implement the big displacement supporting of bearing, meet bridge beam body and bridge pier
Between normal warm deformation at big displacement performance requirement；Second, due to the periphery or symmetrical two on the inside of big displacement sliding panel
End side is provided with limit blend stop, and when slide displacement reaches the limit of at position, it is continued to move to limit blend stop limit value, vibration absorption and isolation support
Can be inside limit blend stop, realization is free to slide within the scope of design displacement, realizes the warm variable displacement requirement of bearing；Third, by
Make the components such as the relatively-stationary shear pin of both or shear studs in being provided between the upper lower support plate for constituting support body,
After when coming earthquake, the components such as shear pin or shear studs are cut, vibration absorption and isolation support, which can be realized, subtracts shock insulation displacement, simultaneously
It can also realize angle turning function when bearing earthquake, improve the bearing subtracts isolation property.

Further instruction.
As shown in Figure 1, 2, it is a kind of composition structure of big displacement active type vibration absorption and isolation support provided by the utility model
Schematic diagram.The structure for constituting the bearing includes constituting the upper bracket plate 21 and lower support plate 22 of support body 2, in upper bracket plate
Upper top be provided with can with the fixed big displacement sliding panel 1 of bridge beam body, and in the big displacement sliding panel and above-mentioned upper bracket
It is provided with the wear-resisting tetrafluoro plate 23 being fixed in upper bracket plate plate face between plate and is fixed on above-mentioned big displacement sliding panel medial surface
Stainless steel plate 12 formed sliding friction pair；And it is symmetrical on composition big displacement sliding panel medial surface as shown in Figure 4
Four sides（Or both sides）End set has the position-limit mechanism that grade item 13 is constituted.
Its working principle is that：The big displacement sliding panel of big displacement active type vibration absorption and isolation support is set to the upper of support body
Portion, the sliding friction pair being arranged between the two can be realized by the wearing pieces such as stainless steel plate and tetrafluoro plate to sliding, for realizing big
Displacement is slided；Big displacement sliding panel for realizing bearing positive room temperature variable displacement；At extreme displacement（On the inside of big displacement sliding panel
Symmetrical four side on face（Or both sides）End）It is provided with limit blend stop（Namely it is provided with grade item 13）, when slide displacement reaches
Extreme position, it is continued to move to limit blend stop limit value, and vibration absorption and isolation support can design inside limit blend stop within the scope of displacement
It realizes free to slide, realizes the warm variable displacement requirement of bearing.
In constituting a kind of above-mentioned big displacement active type vibration absorption and isolation support,
