Description
Technical field
The present invention relates to bridge technology field, is specifically a kind of change type friction pendulum damper bearing.
Background technology
Friction pendulum vibration absorption and isolation support, at home also known as hyperboloid spheroidal bearer of shock absorption and insulation, be it is a kind of from external introduction,
Advanced shock insulation thought applies to embodying for bridge earthquake resistance technical field.1. pendulum principle is utilized, changes structure quake week
Phase, and with earthquake period in expected field away from substantially reducing impact of the earthquake kinetic energy to bridge；2. friction pair significantly consumes energy and reaches
To damping purpose；3. bearing has good auto-reset function, and bearing can automatically revert to original design position, nothing after earthquake
Extraneous force is needed, reduces the maintenance of earthquake rear support difficult.
Existing industry has two standards, respectively JT/T 927-2014 with regard to friction pendulum vibration absorption and isolation support structure《Bridge
Beam hyperboloid spheroidal bearer of shock absorption and insulation》With JT/T 852-2013《Highway bridge friction pendulum vibration absorption and isolation support》, but the two marks
The active type seat structure of quasi- defined cuts both ways.
Standard JT/T 927-2014《Bridge hyperboloid spheroidal bearer of shock absorption and insulation》The active type seat structure of regulation, advantage
It is simple structure, antidetonation clear route, result of the test are consistent with design.Shortcoming is：1. transverse horizontal relative movement space
Greatly, bearing sphere wearing plate is subject to side-friction, service life to substantially reduce for a long time, it is impossible to which the design for reaching bearing uses the longevity
Life；2. bearing is made the reciprocal lifting of bridge structure by conventional external force (the temperature expansion or vehicle braking) effect of the generations such as temperature,
Bridge Impact Coefficient is larger, and long term can produce fatigue damage to bridge structure.
Standard JT/T 852-2013《Highway bridge friction pendulum vibration absorption and isolation support》The active type seat structure of regulation, it is excellent
Shortcoming is just with former conversely, it solves the problems, such as that sphere wearing plate, for a long time by transverse horizontal active force, is also solved
The problem of reciprocal lifting beam body, but the antidetonation route of friction pendulum is inconsistent, and there is one section of idle stroke centre, causes result of the test and sets
Meter demand very different.
The content of the invention
The invention provides a kind of change type friction pendulum damper bearing, to overcome bridge present in prior art
The reciprocal lifting of structure, bearing anti-seismic performance it is bad and bearing sphere wearing plate is rubbed for a long time and service life drops significantly
Low problem.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is summarized as follows：
A kind of change type friction pendulum damper bearing, including hyperboloid, the hyperboloid up and down two it is bent
Be connected with sphere wear-resistant slide plate I and sphere wear-resistant slide plate II on face respectively, the both up and down of hyperboloid be respectively equipped with pendulum and under
Pendulum, is connected with plane wear-resistant slide plate, plane steel plate, the plane steel plate is provided with above the upper pendulum on the upper surface of the upper pendulum
End be provided with down-set steel shoe, it is described under lay out and be provided with upper pendulum stuck steel blocker ring, the steel blocker ring Jing shearing resistances
Pin is fixed on down to be laid out, and is additionally provided with elastomer between the upper pendulum and steel shoe；Under nominal situation or E1 earthquake operating modes, upper pendulum
(wear-resistant slide plate containing plane), hyperboloid (wear-resistant slide plate containing sphere I, sphere wear-resistant slide plate II), the bottom are by steel blocker ring by anti-
Fixed constraint is cut off into a relative entirety, bearing horizontal movement is participated in together with elastomer, the lifting of bridge will not be produced,
The reciprocal lifting of bridge structure is solved the problems, such as, and without relative motion, the resistance to wear smooth of sphere wear-resistant slide plate I, sphere between each component
Plate II is not subject to frictional force, so as to solve the problems, such as that sphere wearing plate is rubbed for a long time and service life is substantially reduced；E2
Under earthquake operating mode, shear-pin is cut off, and upper pendulum, hyperboloid (wear-resistant slide plate containing sphere I, sphere wear-resistant slide plate II), the bottom (contain
Plane wear-resistant slide plate) separate piece is formed, relative plane motion can be produced between each part, because upper pendulum, hyperboloid, the bottom are
Curved face contact, defines friction pendular motion.
More excellent, the compression stiffness of the elastomer is identical with the sliding rigidity value of friction pendulum so that antidetonation route is without turning
Point, anti seismic efficiency is more preferably.
It is more excellent, the sphere wear-resistant slide plate I and sphere wear-resistant slide plate II be set in respectively hyperboloid up and down two it is bent
On face.
More excellent, the plane wear-resistant slide plate is set on the upper surface of pendulum.
Compared with prior art, the beneficial effect produced by the present invention：
(1) after elastomer is set, the idle stroke of friction pendulum has been filled up so that the antidetonation clear route of friction pendulum, continuous, no
Occurs standard JT/T 852-2013 again《Highway bridge friction pendulum vibration absorption and isolation support》The active type bearing of regulation goes out because of idle stroke
Existing flex point；
(2) rigidity of elastomer and the rigidity of friction pendulum are consistent so that anti seismic efficiency is more preferably；
(3) displacement under nominal situation is plane motion, will not produce the lifting of bridge, also solves sphere wearing plate long
Phase is rubbed and problem that service life is substantially reduced.
