[Seismic steel ball bearing]. After the final setting grouting materials, removal of the template and the four corners of the wedge, to check whether tainted slurry at the point of leakage pulp slurry were up when necessary, and the gap wedge with mortar caulking withdrawn after tightening The lower base plate anchors until perfusion concrete beam, each bearing timely removal, under seat bolts, mounting bracket panels, complete seat installation. [Seismic steel ball bearing] characteristics in addition to a general ball bearing angle large, flexible rotation, rotation torque and angle-independent, consistent with the direction of rotation of each performance advantages, but also one with the following six features a large carrying capacity - - Maximum support reaction force may exceed 100000KN; 2, corner large (maximum angle 0.06) 3, greatly enhanced corrosion resistance, can be used in marine atmosphere and splash zone and other harsh environments; 4, the plane sliding and rotating friction is small; 5. Waterproof and durable, steel sliding bearing friction coefficient of friction pair can guarantee non-corrosive, non-polluting; 6, long design life of 100 years by design. [Seismic steel ball bearing]. The main technical performance 1, bearing vertical reaction force from 1000 ~ 100000KN, points 37, it may also require special design projects. 2, the bearing design corner points 0.02 and 0.05 rad two kinds, can also be designed according to the requirements. 3, bearing design displacement: along the bridge to ± 50, ± 100, ± 150, ± 200, ± 250mm, sliding bearings, transverse direction: two-way movable bearing is ± 40mm. 4, friction bearing design series: room temperature (-25 ℃ ~ 60 ℃) ≤0.03. Low temperature (-40 ℃ ~ 25 ℃) ≤0.05. Our country is a country of many earthquakes occur in the aftermath of the earthquake jingchan bearing lateral baffle and anchor shear phenomenon. After the 2008 Wenchuan earthquake, a lot of bridge bearing bolt cut occurred, to recover after the earthquake caused the bridge on the Baoji-Chengdu railway difficulties. How to ensure that in the event of an earthquake bridge support work performance, so the bridge bearings without damaging or minimize damage, and after the earthquake as soon as possible to restore the function of the holder, which is currently a subject to be studied. Seismic steel ball bearings to withstand earthquake forces, there are usually two alternative ways, one way is to increase the seat anchors seismic grid sliding bearing AAA level, sufficient to withstand the shear forces caused by earthquakes, this When the earthquake force transferred from the holder of all to the pier, it may cause damage to the pier, so that a small amount of displacement of the bearing can occur, but does not occur off the beam, and seat anchors cut does not occur, QZ ball slide bearing R & D production, which can reduce the effect of seismic force appropriate to the pier. To this end it is necessary to Research on a seismic steel ball bearings. Qiantang River Bridge is 45m + 65m + 14 × 80m + 65m + 18 holes prestressed concrete box beam bridge 45m ties, length 1340m, located only two fixed piers in the middle of a full-bridge, full-bridge longitudinal horizontal seismic force of will be undertaken in the manufacture of friction by providing both fixed bearing fixed piers and all the activity on the pier on the resistance, for in addition to setting the necessary bridge design seismic stoppers, the use of seismic steel ball bearings.
