Secondary Milling Machining, the processing technology of the groove is complicated, machining accuracy is relatively low, and processing cost is relatively high；
(2) isotropism, the plane projection that conventional friction puts the upper bracket plate and lower support plate of support is circle, upper branch
Seat board, lower support plate are identical in parameters such as radius of curvature, the coefficient of frictions of all directions, its all directions is caused to subtract shock insulation rigidity, resistance
Damping characteristics are identical, and be unable to satisfy bridge structure different directions subtracts isolation property demand；
(3) slide plate durability is insufficient, and traditional friction pendulum support slide plate is frequently with polyfluortetraethylene plate or modified superelevation point
Sub- weight polyethylene board.In actual use, the abrasion resistance of polyfluortetraethylene plate and dimensional stability are not ideal enough, need
Improve the abrasion resistance of polyfluortetraethylene plate by adding suitable filler or adding silicone grease lubrication.In the feelings for being coated with grease of silicone fluid
Under condition, the coefficient of friction of support for friction pendulum support generally 0.01 hereinafter, cannot play good damping.Separately

Meet the high requirement of high intensity Zone wearing plate resistance to rapid wear resistance.
Therefore, the assembling degree of traditional friction pendulum support is lower, cannot achieve bridge structure based on performance requirement
Anisotropy seismic isolation design, and the durability of sliding material is poor, can not effective guarantee bridge structure safety.For reality
The high-precision assembling production of existing bridge pad, realizes that the anisotropic of bridge structure subtracts shock insulation demand, improves the resistance to of support
Long property needs to research and develop novel friction pendulum support.

The company of shear-pin 11 can be set in the upper surface block 3 of upper bracket plate component 21, the lower end surface block 4 of lower support plate component 22
Outbound hole 15, upper liner plate 5, bottom deck 6 two sides shearing-resistance blocks 12 can be set.By to upper bracket plate component 21 and upper liner plate
5, whether the shearing resistance component of shear-pin 11 and the composition of shearing-resistance blocks 12 is installed between lower support plate component 22 and bottom deck 6, can be incited somebody to action
Support separately designs as longitudinal sliding motion type support, slides laterally type support, bi-directional sliding-type support and fixed support.
Specifically, when assembled friction pendulum support constitutes longitudinal sliding motion type support, upper bracket plate component 21 and upper liner plate 5 it
Between installation shear-pin 11 and shearing-resistance blocks 12 form shearing resistance component, shearing resistance is not installed between lower support plate component 22 and bottom deck 6
The shearing resistance component that pin 11 and shearing-resistance blocks 12 form, bottom deck 6 can be longitudinal in the second concave spherical surface 14 of lower support plate component 22
Or the one direction in a certain drift angle direction is free to slide；
It is uneasy between upper bracket plate component 21 and upper liner plate 5 when assembled friction pendulum support composition slides laterally type support
Fill the shearing resistance component that shear-pin 11 and shearing-resistance blocks 12 form, installed between lower support plate component 22 and bottom deck 6 shear-pin 11 with
The shearing resistance component that shearing-resistance blocks 12 form, upper liner plate 5 can be lateral or a certain in the first concave spherical surface 13 of upper bracket plate component 21
The one direction in drift angle direction is free to slide；
It is uneasy between upper bracket plate component 21 and upper liner plate 5 when assembled friction pendulum support constitutes bi-directional sliding-type support
The shearing resistance component for filling shear-pin 11 and the composition of shearing-resistance blocks 12, does not install shear-pin 11 between lower support plate component 22 and bottom deck 6
With shearing-resistance blocks 12 form shearing resistance component, upper liner plate 5 can in the first concave spherical surface 13 of upper bracket plate component 21 laterally or certain
The one direction of one drift angle direction is free to slide, and bottom deck 6 can be indulged in the second concave spherical surface 14 of lower support plate component 22
To or a certain drift angle direction one direction it is free to slide；
When assembled friction pendulum support constitutes twin fixed guide-vane type support, upper bracket plate component 21 and upper liner plate 5, lower support plate
The shearing resistance component of shear-pin 11 and the composition of shearing-resistance blocks 12, support sliding in the horizontal direction are respectively mounted between component 22 and bottom deck 6
It suffers restraints.
Under the operating conditions such as automobile mobile load, temperature action, big wind load and small earthquakes, shear-pin 11 with 12 groups of shearing-resistance blocks
At shearing resistance component can limit bridge main beam and bridge pier and occur relative motion, support can along the direction of not set shearing resistance component into
Row one direction freely slides, and meets the displacement demand of bridge；Under violent earthquake operating condition, seismic support horizontal force is greater than anti-
The shear-carrying capacity of component is cut, shear-pin 11 is cut, and sliding of the shearing resistance component no longer to support in the direction constrains, branch
Seat plays damping energy consumption function.
Further, the upper bracket plate 1, lower support plate 2, upper surface block 3, lower end surface block 4, upper liner plate 5, under hold

1500MPa is measured, and the slide plate dry grinds time-consuming line abrasion less than 20 μm/km in 45MPa face pressure, 15km over long distances, guarantees assembled
Friction pendulum support (speed is greater than 0.4m/s) under quick Frictional Slipping normally plays it and subtracts shock insulation function.
Storage need to be arranged in the modified ultra-high molecular weight polyethylene or other Polymer Friction Materials, surface that middle slide plate 8 uses
Oil groove need to fill up dedicated 5201 silicone grease of bridge pad in support assembling in oil storage tank, to realize that liner plate 5 is under on support
Freely horizontal, vertical rotating between board 6.
The assembled friction pendulum support of the present embodiment, in assembling production, first to the recessed ball of upper bracket plate, lower support plate
Face carries out Machining of Curved Surface, then connect to form upper bracket plate component, lower support plate component with facing stop by connecting bolt respectively,
It is finally quickly assembled with upper liner plate, bottom deck and forms support entirety, realize the high-precision of support, the dress of high efficiency, low cost
It is produced with metaplasia；In seismic isolation design, respectively to upper bracket plate, lower support plate groove radius of curvature, slip length, coefficient of friction
It is separately designed, realizes anisotropy seismic isolation design of the bridge based on performance；Meanwhile in slide plate durability selection, root
According to the use function of different slide plates, upper slide, lower skateboard select very-high performance fluorine material (UHPF), and middle slide plate selects band oil storage
The ultra high molecular polyethylene slide plate of groove.Under the premise of function is identical, high relative to conventional friction pendulum support assembling degree,
Durability is good, at low cost, subtracts shock insulation clear mechanism, and applicability is wide.
