Description
Technical field
The present invention relates to bridge pad and device, in particular to a kind of level for being connected between bridge beam body with bridge pier to adjustable seats.
Background technology
The critical component that bearing is formed a connecting link as bridge, the counter-force of bridge superstructure and deformation (displacement and corner) can be passed to bridge substructure by reliably.The bearing that current China railways adopts mostly is pot rubber bearing and ball shaped steel bearing, and corner is generally ± 0.02rad, and the supertronic of wide-angle need to by adding the realizations such as wedge.
The compression rotating through rubber blanket of pot rubber bearing realizes, corner is usually more than ± 0.02rad, the demand of large rotation angle can not be met, the supertronic of wide-angle need to by adding the realizations such as wedge in bearing upper end, but practice of construction difficulty is big, operating process is difficult to control, and owing to work progress exists error, it is difficult to ensure that wedge lower surface is that face contacts with upper surface of support, and often become linear contact lay, make beam body part come to nothing, cause upper surface of support discontinuity, reduce the service life of bearing.
Spherical steel support is a kind of novel bridge bearing grown up on the basis of pot rubber bearing, it may be achieved the demand of large rotation angle, is characterized in that level angle is big, high-bearing capacity, abrasion performance, but there is unstability when bearing large rotation angle supertronic and be likely to.
Additionally, the railcar train of the high-speed transits such as magnetic suspension train, linear to circuit has very high required precision, under the effect of track dead load and load, it is inevitable that later stage produces foundation uneven settlement, especially dislocation that differential settlement causes between two adjacent bridge piers upper track beam is linear and sudden change, for being definitely unallowed as this kind of high-speed track transportation system of magnetic suspension train.Therefore, after exceeding the displacement that train rail allows, it is necessary to track girder is adjusted.Current track beam support regulates by adding wedge and moving back the modes such as wedge and realize in horizontal direction, and practice of construction difficulty is big, and operating process is difficult to control.
Such as, the adjustment of Shanghai Maglev bearing lateral displacement is by taking out in both lateral sides, inserting gag, and promotes the mode that stud base slides on base plate to realize lateral adjustments, and structure is more complicated, because there being clapboard, gag etc., horizontal force is also more complicated；And realize single direction (transverse direction) only to regulate, it is impossible to enough each levels that realizes truly regulate.
Thus how in conjunction with the requirement of magnetic suspension bearing, design meet level regulate to displacement require, safe and reliable bearing is urgently research and one of key technology of solving.
