Description
Technical field
The invention belongs to bridge structure bearing technical field, especially relate to a kind of track traffic ultrahigh water
Flat power high-durability spherical bearing.
Background technology
Bridge pad is to connect bridge superstructure and the important feature parts of substructure, and it is by bridge
The counter-force of portion's structure and deformation (displacement, corner) are reliably delivered to bridge substructure, ensure bridge
The power transmission of structure, stress are clear and definite.Spherical bearing is as a kind of version of bridge pad, at the very start
Being favored by engineering circles, it has lot of advantages, rotates flexibly, and amount of spin is big, respectively to rotating property
Unanimously, vertical bearing capacity is strong, allows that support displacement is big, and owing to bearing is without rubber pressure-bearing, no
There is the impact of ageing of rubber, durability is higher, is current railroad bridge and first-selected the propping up of Longspan Bridge
One of seat form.
World wide earthquake disaster for many years shows, along with the development of urbanization, transportation network is in whole city
In city's Seismic Resistance And Disaster Reduction lifeline engineering more and more important.Domestic bridge earthquake resistant design code of being correlated with all proposes
Many levels, multistage requirement of setting up defences, as " urban track traffic seismic design of structures specification " specifies,
Structure should be followed the anti-seismic performance of three levels and set up defences target.Performance requirement I: do not break after requiring structural earthquake
Go bad or slight damage, its normal usage function should be able to be kept；Structure is in the elastic working stage；Not Ying Yin
The deformation of structure causes the excessive deformation of track to affect traffic safety；Performance requirement II: after structural earthquake
May destroy, through repairing, its normal usage function should be able to be recovered in a short time；Structure partial enters elastoplasticity
Working stage；Performance requirement III: may produce relatively havoc after structural earthquake, but should not occur local or
Entirety is ruined, and structure is in elastoplasticity working stage.And specify, when bridge structure uses preferable ductility
When being designed, for performance requirement II and performance requirement III, be required to bearing can keep normal function,
Without changing.
Therefore, when bridge carries out preferable Ductility Design, the requirement to bearing performance is greatly improved, especially
Its when bridge be in that fortification intensity is higher or seismic acceleration peak value is bigger regional time, the water that bearing bears
Flat power will be quite big, exceedes the bearing horizontal force size of current specification defined.If it addition, bearing
Once it is destroyed, bearing is replaced and constructs cumbersome, and the operation on circuit produces impact,
And increase bridge inspection and maintenance expense.It is therefore necessary to design a kind of superelevation horizontal force and the bearing of high-durability,
Ensure the normal function of big shake rear support and without changing.
Summary of the invention

Further, the early stage of described anchor rod, upper base plate, lower seat board and spherical crown liner plate processes and at application
Reason process is as follows:
First remove quench-hardened case and oxide skin, chamfering that oxygen machining produces；Carry out after surface defat is clean again
Sandblasting or Shot Blasting；After rear injection process, spraying zinc aluminized coating in a period of time, uses epoxy immediately after
Paint seals；Finally, by technological requirement spraying epoxy micaceous iron intermediate coat and fluorine carbon finishing paint.
Further, the surface of described anchor rod is provided with the diagonal rib of projection.
Further, the outer edge of anchor rod and the outside of upper base plate at described upper base plate two ends is in one and erects
On straight straight line.
Further, described upper base plate and the upper base plate edge of a wing are formed in one structure or weld together.
Further, described planar lasting board and spherical wearing plate are super-high wear-resistant plate UHMWPE.
Relative to prior art, present invention have the advantage that
(1) variable cross-section by arranging the inverted trapezoidal upper base plate edge of a wing, anchor rod uses lower end to amplify reaches
The effect of bearing superelevation horizontal bearing capacity, so that it is guaranteed that bearing under big shake effect still in the shape that normally works
State, exempts the various disadvantageous problem that bridge is brought by replacing time；
(2) by using super-high wear-resistant plate UHMWPE and spherical bearing new formula protective system to realize
The high-durability ability of bearing；
(3), by the way of the groove arranged by lower seat board and the protuberance on the upper base plate edge of a wing are combined, come
Realize the function of the vertical anti-pulling of bearing；
(4) bearing and bridge same life-span, free of replacement under normal condition, maintenance cost saving, reduce right
The impact of circuit operation, and eliminate various disadvantageous to the bridge problem that replacing time brings；And knot
Structure is simple, materials save, lightweight, simple installation.
