The present invention is applied to the bridge pier of different section size, and the processing and fabricating of attachment means can be according to the spirit of bridge pier cross dimensions
Processing living is selected.Had concurrently after attachment means installation and prevent hitting landscape function, its exposed surface can be as requested from difference
Color carries out anticorrosive coating.
（1）The design of the pre-buried fining twisted steel tendons skeleton of cushion cap
The pre-buried fining twisted steel of cushion cap is embedded into cushion cap and carried out by upper and lower fixing steel plate and metal sleeve connection composition skeleton
Positioning；Finish rolling deformed bar is fixed in bottom by flat anchorage（As fixing end）, adopted by and according to bridge pier form
With different intensity grades, the finish rolling deformed bar of specification.
（2）The welding design of steel plate, steel plate and U ribs
Steel plate and U ribs are designed using weathering steel, during practice of construction, need to select matching welding rod；Weld shape
Formula is according to actual conditions using Type of Welding such as penetration weld, groove welding, fillet welds.
（3）Position Design
This part includes pre-embedded steel slab above and below inside cushion cap, finish rolling deformed bar, U ribs, pier bottom steel plate and passes through hole and upper pressure-bearing steel
The Position Design of plate position of opening.Each component for being participated in is pre-buried or installation before, need to be in factory to its package unit system
Preassembling is carried out, to ensure to agree between a full set of system and the degree of deviation is in the permissible range of design；The reinforcing bar of the pre-buried part of cushion cap
Skeleton should determine its flat orientation when pre-buried according to pier location, and strictly control its levelness and finish rolling deformed bar
Vertical degree.
（4）Post jacking designs
By respectively opening aperture at one in U ribs top/bottom part, then pressure injects grouting material, to ensure U ribs inside and fining twisted steel
Muscle is not by the corrosion of steam etc., so as to ensure the safety durable of structure.
（5）Anticorrosive coating designs
The external environmental conditions such as air, the hydrology according to residing for bridge, matching anticorrosive coating system is selected, and use band
There is the application color of alarming effect, while steel plate antiseptic effect is reached, take into account the anticollision effect of bridge pier.
The present invention use steel plate outsourcing+U ribs+fining twisted steel type of attachment precast assembly bridge pier, by outside steel plate+
U ribs+finish rolling deformed bar undertakes superstructure and load is transmitted in earthquake：It is i.e. internal by welding perforated panel in encased steel plate
+ the mode for running through reinforcing bar forms PBL shear connectors, reaches internal cage bar and transmits load to the purpose of encased steel plate；Outside is by outer
Common stress between steel plated, U ribs and finish rolling deformed bar, pier shaft load is transmitted to cushion cap, the stress of guarantee precast assembly bridge pier
Performance meets design requirement；Finish rolling deformed bar is embedded in inside cushion cap, while precast pier pier bottom（Containing encased steel plate and U ribs）
It is embedded to inside cushion cap, pier shaft is formed overall guarantee reliability with cushion cap.U ribs are using weather-proof steel and internal grouting, to ensure
The durability of finish rolling deformed bar and steel plate；U ribs and exposed steel plate use the anticorrosive coating with warning mark, while U ribs are certainly
Body may also function as the effect for absorbing Impact energy, to play a part of anticollision device, collision-prevention device.
