The repertoire such as dynamic.After the earthquake, ruptured by longitudinal safety, horizontal safety, the longitudinal steel damping element of release,
Laterally steel damping element is so as to participate in motion, plastic deformation dissipation seismic energy reduces seismic energy repeatedly by damping element
Amount input, reaches the minimizing destruction to bridge for the earthquake, the purpose of protection pier and structure.
For avoid unilateral longitudinal direction steel damping element 18 in motor process due to unilateral stress cause lower guideway assembly 7 with
The lower guideway groove of slip board component 5 is stuck, setting balance block assembly 8, carries out stress balance, prevent because lower guideway assembly 7 with
Slip board component 5 is stuck, affects properties of product.By between the lower guideway groove of lower guideway assembly 7 and lower slider board component 5,
Between the upper rail groove of upper rail assembly 9 and upper sliding plate assembly 1, balance block assembly 8 and the setting of lower slider board component 5 vacant side
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 prior art is described further.
In prior art, seat structure damping element arrangement adopts traditional bilateral unfolding wing type arrangement, and bearing is installed
Many big compared with general bearing of demand space, in the present invention, seat structure reduces to requirements of installation space, and Installation Flexibility is high, more
Can be suitably used for Medium and small span bridge.Compared with prior art, the main following points of the difference of the present invention: 1, this
Bright using being longitudinally, laterally respectively arranged longitudinal safety, horizontal safety it is ensured that product plays common in general
Seat effect, in the case of seismic events, being consumed energy by damping element, to reduce seismic energy defeated for plastic deformation dissipation seismic energy repeatedly
Enter, reduce the destruction to bridge for the earthquake；2, the present invention adopts unilateral double damping force structure arrangement, vacant side, reduces vertical bridge
To requirements of installation space, improve product Installation Flexibility；3rd, the present invention passes through setting balance block assembly, carries out stress balance, prevents
Only because lower guideway assembly is stuck with lower slider board component, affect properties of product；4th, the present invention passes through the lower slider plate in vacant side
Balance weight chute is arranged on assembly, forms friction pair it is ensured that when reconciliation of inventory block assembly is to stress balance with balance block assembly, no
Impact product slides and rotating property.In a word, compared with prior art, by arrangement above, make the unilateral resistance of indication of the present invention
Buddhist nun's elastoplasticity bridle iron is in addition to possessing the various functions of traditional elastoplasticity steel damping supporting seat moreover it is possible to be completely adapted to the peace in little 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), can be using fractionation
Or change shape；Block assembly is balanced to critical component, again can be split using the method that parts split；Can be to key structure
Balance block assembly and connected mode change used by lower slider board component friction pair.
