The utility model has the following advantages：
1）Under normal operating condition and design geological process, flexible carbon fiber limit drag-line does not influence the normal position of bearing
It moves and rotates.When rarely occurred earthquake acts on, the horizontal Self-resetting performance of bearing can be improved in carbon fiber limit drag-line, can effectively avoid
The risk for falling beam is generated because beam body displacement is excessive.
2）On the basis of giving full play to conventional friction pendulum vibration absorption and isolation support advantage, the spacing-type friction pendulum subtracts shock insulation branch
Seat also have bearing capacity strong, Self-resetting and girder falling performance is good, superior durability, limit reliably, simple structure, it is cheap,
The advantages that being conveniently replaceable.
3）Carbon fiber limit drag-line may be disposed on any two direction of all types of bearings, and limit drag-line is because of earthquake displacement
It is excessive and when being tensioned can earthquake energy, and be set to sleeve hollow bolt and anchor the buffer spring washer between tapered end
It can play the role of effective buffering energy-consumption.
4）The active length that carbon fiber limits drag-line can be easily adjusted by anchoring tapered end position.
5）The utility model is applicable on all kinds of bridge structures such as railway, highway, municipal administration, damping, shock insulation, limit
And girder falling is with obvious effects.

Specific implementation mode
The utility model is described in detail With reference to embodiment.
The utility model is related to a kind of spacing-type friction pendulum vibration absorption and isolation support, including upper bracket plate 22 and lower support plate 12,
22 bottom surface of upper bracket plate and 12 top surface of lower support plate are concave spherical surface, dock in space and are provided with spherical crown liner plate 14.Upper bracket plate
22 and lower support plate 12 concave spherical surface on be both provided with slide plate.22 top surface of upper bracket plate is provided with the upper anchoring rod iron for anchoring
21,12 bottom surface of lower support plate is provided with the lower anchoring rod iron 11 for anchoring, and entire seat structure passes through lower 11 He of anchoring rod iron
Upper anchoring rod iron 21 is anchored between pier and beam body.There is 22 bottom surface of upper bracket plate boss, boss periphery to be provided with correspondence and open
The baffle 32 in hole, baffle 32 are fixed to lower support plate 12 by shearing bolt 31.Baffle 32 is used to constrain the pendulum of spherical crown liner plate 14
Dynamic amplitude.
Carbon fiber is set between the upper bracket plate 22 and lower support plate 12 of bearing and limits drag-line 41, carbon fiber limits drag-line
41 be flexible structure, is made of high-strength flexible carbon fibre material.41 end of carbon fiber limit drag-line is outer successively to be cased with sleeve sky
Heart bolt 42 and buffering spring washer 43,43 outer end of buffer spring washer setting anchoring tapered end 44, carbon fiber limit 41 end of drag-line
Portion is inserted into and is welded among the embedded sleeve barrel 45 in upper bracket plate 22 and lower support plate 12, is bolted to by sleeve hollow bolt 42
In embedded sleeve barrel 45.The active length of carbon fiber limit drag-line 41 can be easily adjusted by adjusting the position of anchoring tapered end 44.
Active length, radical and the sectional area that carbon fiber limits drag-line 41 can be calculated really by horizontal earthquake displacement and seismic force
Fixed, carbon fiber limit drag-line 41 may be disposed at all types of bearings such as hold-down support, one-way movable support and bi-directional movable bearing
On any two direction, carbon fiber limit drag-line 41 because earthquake displacement is excessive be tensioned when can earthquake energy, and be set to
Buffer spring washer 43 between sleeve hollow bolt 42 and anchoring tapered end 44 can also play the role of effectively buffering, energy consumption.
Under normal operating condition and under design geological process, by being anchored in lower support plate 12 with shearing bolt 31
