Part 18 is not involved in moving in normal state, under geological process, after longitudinal safety device 14 is cut, participates in movement, damping consumption
Energy.
11 top of piston component is provided with upper rail component 9 protruding upward, between the upper rail slot of upper sliding plate component 1
Gap coordinates, and realizes the direction across bridge stress and guide function of unilateral damping elastoplasticity bridle iron.3 lower part of bottom basin component is provided with downwards
The lower guideway component 7 of protrusion, the lower guideway slot clearance fit with downslide movable plate component 5 realize unilateral damping elastoplasticity bridle iron
Vertical bridge to stress and guide function.
Under normal circumstances, unilateral damping elastoplasticity bridle iron passes through longitudinal safety device, horizontal safety device limitation longitudinal direction
Steel damping element, horizontal steel damping element movement, are slided, bottom basin component 3 by the way that downslide movable plate component 5 and lower wearing plate 6 are opposite
Opposite with planar lasting board 12 to slide, middle seat board 4 is relatively rotated with spherical surface wearing plate 2, upper sliding plate component 1 and upper wearing plate 10
It is opposite slide and guide rail structure function can realize vertical carrying, horizontal force and the guiding of conventional ball type bearing, sliding, turn
It is dynamic to wait repertoires.After the earthquake, it is broken by longitudinal safety device, horizontal safety device, the longitudinal steel damping element of release,
Horizontal steel damping element makes it participate in movement, is plastically deformed dissipation seismic energy repeatedly by damping element to reduce seismic energy
Amount input reaches the destruction for reducing earthquake to bridge, protects the purpose of pier and structure.
To avoid unilateral longitudinal steel damping element 18 during the motion since unilateral stress causes lower guideway component 7 under
The lower guideway slot of sliding panel component 5 is stuck, sets balance block assembly 8, carries out stress balance, prevents because lower guideway component 7 is under
Sliding panel component 5 is stuck, influences properties of product.By between the lower guideway slot of lower guideway component 7 and downslide movable plate component 5,
Between upper rail component 9 and the upper rail slot of upper sliding plate component 1, balance block assembly 8 and the setting of 5 vacant side of downslide movable plate component
Friction pair and lubricant medium, to reduce sliding-frictional resistance.
Below by way of compared with the prior art, the difference of the present invention and the prior art are described further.
In the prior art, seat structure damping element arrangement is mostly using traditional bilateral unfolding wing type arrangement, bearing installation
The more general bearing of demand space will be big it is more, seat structure reduces requirements of installation space in the present invention, Installation Flexibility height, more
It can be suitably used for Medium and small span bridge.Compared with prior art, the main following points of difference of the invention：1st, this hair
Bright use longitudinally, laterally is respectively arranged longitudinal safety device, horizontal safety device, ensures that product plays common branch under normal circumstances
Seat effect in the case of seismic events, it is defeated to reduce seismic energy to be plastically deformed dissipation seismic energy repeatedly by damping element energy consumption
Enter, reduce destruction of the earthquake to bridge；2, for the present invention using unilateral double damping force structure arrangement, vacant one side reduces vertical bridge
To requirements of installation space, product Installation Flexibility is improved；3rd, the present invention balances block assembly by setting, and carries out stress balance, prevents
Only because lower guideway component and downslide movable plate component are stuck, properties of product are influenced；4th, the present invention passes through the downslide movable plate in vacant side
Balance weight sliding slot on component is set, forms friction pair with balance block assembly, when ensureing reconciliation of inventory block assembly to stress balance, no
Influence product slip and rotating property.In short, compared with prior art, with the above arrangement, making the unilateral resistance of meaning of the invention
Buddhist nun's elastoplasticity bridle iron is in addition to the various functions for possessing traditional elastoplasticity steel damping supporting seat, moreover it is possible to be completely adapted to the peace in small space
Reload request realizes the function of seismic resistance of Medium and small span bridge.
In the present invention, to critical component damping element（Horizontal steel damping element, longitudinal steel damping element）, fractionation can be used
Or change shape；Block assembly is balanced to critical component, the method that parts fractionation can be used is split again；It can be to key structure
Block assembly is balanced to change with connection mode used in downslide movable plate component friction pair.
The foregoing is only a preferred embodiment of the present invention, is not intended to limit the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.Within the spirit and principles of the invention, that is made any repaiies
Change, equivalent substitution, improvement etc., be all contained within protection scope of the present invention.
