A kind of compound bridge friction pendulum support device, including upper groove concave surface, lower channel concave surface, upper sliding plate, under
Sliding panel, on be hinged sliding block, under be hinged sliding block and steel ball;The lower surface of the upper groove concave surface and the upper table of upper sliding plate
Face is hinged, and forms the first friction pair;The lower surface of the upper sliding plate is hinged with being above hinged the upper surface of sliding block, is formed second and is rubbed
Wipe secondary;The lower surface and steel ball that sliding block is hinged on described are hinged, and form the 3rd friction pair;The steel ball is hinged sliding block with
Upper surface be hinged, formed the 4th friction pair;The upper surface that the lower surface and lower slider plate of sliding block are hinged under described is hinged, and is formed
5th friction pair;The lower slider plate is fixedly connected with lower channel concave surface.The present invention consumes energy to reduce ground by sliding friction
Shake acts on the influence to bridge superstructure displacement, effectively reduces harm of the earthquake to bridge superstructure crossbeam.
First concave surface of upper groove concave surface lower surface interacts with upper sliding plate upper surface, make upper sliding plate to
On be hinged sliding block one vertical constraint be provided;Second concave surface of lower channel concave surface upper surface is fixed with lower slider plate, is made
Lower slider plate, which is given down, is hinged the vertical constraint of sliding block offer one.
The upper sliding plate both sides are provided with upper baffle ring, and the lower slider plate both sides are provided with lower baffle ring, described for limiting
It is hinged sliding block and sliding laterally for sliding block is hinged with, controls stand apparatus maximum displacement.
Be hinged on described first sphere of sliding block lower surface and under be hinged the second sphere and steel ball phase of sliding block upper surface
Coordinate.
Compared with prior art, the characteristics of present invention has following prominent and significant technological progress:
The present invention is by slide up and down plate and is hinged the slip of sliding block and the rolling of steel ball up and down so that bridge is in earthquake
The relative displacement of the lower all directions of effect meets the requirements;It is cheap;Isolating affection is good;Have wide range of applications.
