Abstract
The utility model discloses an anti-seismic bridge bearing, and belongs to the technical field of bridge bearings. According to the technical scheme, the anti-seismic bridge bearing comprises a pier body, a beam body, main bearing bodies, supporting pillars, bearing bodies, main anchor bearings, anchor bearings, inhaul cables and adjusting cushion blocks. The anti-seismic bridge bearing is characterized in that the main bearing bodies, the supporting pillars and the bearing bodies are arranged between the pier body and the beam body, one inhaul cable device is arranged on one side of one of the main bearing bodies, another inhaul cable device is arranged on the side, opposite to the side of the main bearing body, of the other main bearing body, each inhaul cable device comprises one of the main anchor bearings, one of the anchor bearings and one of the inhaul cables, the main anchor bearings are fixedly arranged on the top of the pier body, the anchor bearings are arranged on the bearing bodies, the two ends of each inhaul cable are connected with the corresponding main anchor bearing and the corresponding anchor bearing in an anchoring mode respectively, and each adjusting cushion block is fixedly arranged on the portion, opposite to the outer side wall of the corresponding supporting pillar, of the corresponding main anchor bearing. Compared with the prior art, the anti-seismic bridge bearing is simple in structure and convenient to construct, and has the reliable longitudinal beam falling prevention function and the firm transverse beam falling prevention function, effective matching between the longitudinal beam falling prevention function and the transverse beam falling prevention function is achieved, displacement can be eliminated in multiple directions, and the anti-seismic bridge bearing is especially applicable to linear or curved bridge structures in high-intensity regions.
Description
Technical field
The utility model relates to bridge pad technical field, relates in particular to a kind of bridge girder anti-seismic bearing.
Background technology
Bridge pad is the vitals that connects bridge superstructure and substructure, and it can pass to bridge substructure reliably by the counter-force of bridge superstructure and distortion, thereby makes the actual loading situation of structure and graphic being consistent of theory of calculating.For reaching above requirement, at present, in bridge construction, generally adopt pot rubber bearing, its structure generally comprises upper steel plate, middle steel plate, block rubber, polyfluortetraethylene plate, sealing ring, end basin etc.It utilizes Incoercibility and the high damping properties of block rubber, alleviate bridge superstructure and dynamic load and impacted the top counter-force producing, resistance to compression and the antidetonation shock-absorbing capacity of whole bridge are improved to a certain extent, but still there is following problem: the one, install cumbersome, between upper steel plate and all parts and bearing body, generally all fix with screw, site operation is wasted time and energy, and whole bearing seems more complicated; The 2nd, resist displacement shock resistance is poor, because upper steel plate, middle steel plate are all plane contact, lacking again can spacing property and engaging support mechanism, so in the time that it is subject to multi-direction vibrations, upper steel plate just can not produce the movement of inclining accordingly thereupon, so just easily make bridge impaired, the anti-multi-direction vibrations poor-performing of bridge, application life is relatively short.
Utility model content
The purpose of this utility model is the deficiency existing for prior art, and a kind of simple in structure, easy construction, anti-seismic performance and the stronger bridge girder anti-seismic bearing of resist displacement ability are provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of bridge girder anti-seismic bearing, comprise pier body, beam body, main bearing, pillar, bearing, Bower Anchor seat, anchoring part, drag-line and adjustment cushion block, between described pier body and beam body, be provided with main bearing, pillar and bearing, main bearing both sides are provided with cable arrangement, described cable arrangement comprises Bower Anchor seat, anchoring part and drag-line, described Bower Anchor seat is fixedly installed on pier body top, on described bearing, be provided with anchoring part, described drag-line two ends respectively with Bower Anchor seat, anchoring part anchor connection, described Bower Anchor seat is fixedly installed adjustment cushion block on the position relative with pillar lateral wall, described bearing comprises upper steel plate, rubber tile, middle steel plate and support arm, described upper steel plate end is bent downwardly and extends into bottle cap shape, the end of described bending forms dop, in the upper steel plate of described bottle cap shape, be wrapped in successively rubber tile and middle steel plate, the upper end of described support arm and middle steel plate form one, the lower end of support arm is spherical termination, in the middle of described pillar, be provided with a ball recess, the spherical termination of described support arm is arranged in ball recess, on the outer wall of described pillar, be provided with a flute profile recess, the dop of described upper steel plate is arranged in flute profile recess.
The beneficial effects of the utility model are: 1, simple in structure, and easy construction, because upper steel plate is bottle-cover-shape, rubber tile and middle steel plate are positioned at wherein, have simplified the trouble of site operation; 2, the spherical termination on support arm coordinates with the ball recess on pillar, expanded with heat and contract with cold or be subject to seismic while rocking produced displacement at bridge, utilize the multiple-directional rotating principle of spherical arc, can eliminate easily displacement, simultaneously, dop both can rotate owing to being stuck in flute profile recess in certain interval, had prevented that again upper steel plate from, because the displacement producing compared with big bang departs from bearing, having improved its pull resistance; 3, the utility model had both had reliably longitudinally girder falling function, had again firmly laterally girder falling function, effectively collocation in length and breadth, and elimination displacement that can be multi-faceted, is specially adapted to straight line and the Curved Bridges in high earthquake intensity area.
