Ethene spherical slide plate, stainless steel flat plate is provided between the upper bracket plate and tetrafluoroethene circle flat runner, it is characterised in that：
Some ducts are provided with the upper surface of the upper bracket plate and the lower surface of lower support plate, a drag-line alternately passes through successively
Corresponding duct forms winding arrangement on support plate, lower support plate, and the both ends of drag-line are exposed at upper bracket plate with adjacent respectively
It is fixed together with the drag-line part outside lower support plate by cable clamp.
Further, cover plate is provided with the upper surface of the upper bracket plate and lower support plate lower surface, by drag-line and duct
Covered.
Further, the drag-line is steel wire rope, steel strand wires, carbon fiber bundle or chain.
Further, one end of the drag-line is fixed with the adjacent drag-line part being exposed at outside upper bracket plate and lower support plate
The quantity of cable clamp is 1 ~ 3, ensures fixed reliability.
Further, the exposed part surface outside upper bracket plate and lower support plate of the drag-line set rubber sleeve or
Vulcanised rubber layer, exposed drag-line part is protected, improve service life.
Further, lubricating grease is filled with the duct, local pull is carried out when being easy to wind drag-line and is adjusted, simultaneously
Drag-line can be protected.
The beneficial effects of the utility model are：
1. a structure is the unidirectional aseismatic bearing of bracing cable for bridge girder falling, add on unidirectional quake-proof ball-shaped support architecture basics
Fill drag-line（Such as steel wire rope, steel strand wires, carbon fiber bundle or chain high-intensity performance material cords）So that upper bracket plate is with
It is flexible overall that support plate connects into one within the specific limits so that bearing proper motion in drag-line winding space, beyond drag-line
Winding space support movement is obstructed, and the motion of holder top beam body is limited when reaching susceptor design earthquake maximum displacement, is reached
Preventing and treating beam body come off pier situation occur.This structure can effectively solve bridge superstructure in earthquake or other fortuitous events
Lower preventing and treating beam body departs from pier, the accident for causing beam body to come off.
2. the beam in the utility model can be used for preventing bridge top during earthquake with the unidirectional aseismatic bearing of drag-line girder falling
Beam body departs from the bridge of bridge pier, it can also be used to needs to limit the special construction bridge of bridge top beam body space.
3. the beam unidirectional aseismatic bearing collection anti-fall girder apparatus function of drag-line girder falling and antidetonation branch in the utility model
Seat function is in one, and installation is simple, design optimization, and cost is cheap.
