Position pin；Realize bearing fixed effect.
Advantageous effect：
1 by increase spherical bearing spherical crown liner plate curvature, radius of curvature increase by 25%.By conventional seat corner
0.02rad increases to 0.04rad.Realizing, razor-edge liner need not be arranged in the case where the longitudinal and transverse slope of bridge is not more than 4%, convenient
Construction, adapts to beam bottom slope errors automatically.
2 are placed on horizontal sliding surface on the bearing pad stone of lower section, that is, spherical surface (is in ball shaped steel bearing bottom in the present invention
Bearing), construction quality is easily guaranteed that, has also further ensured the performance of bearing.
3 are additionally arranged horizontal level meter in undersetting steel plate both direction, to ensure horizontal sliding surface level, are also convenient for
Construction and later stage Inspection and maintenance.
4 is adapt to construction time great slope (i.e. corner), and one-way support is changed to intermediate one by conventional both sides plate washer, Gu
Determine bearing and is changed to central spacer pin.
Novel monodisplacement bearing is slotted, slot, which is embedded in, leads by Fig. 2 in the position of center line of lower seat board and spherical bearing
To flat key.Both bearing length travel had been met, and had had and meet bearing cross spacing.
Novel hold-down support processes circular hole, setting is fixed in hole by Fig. 2 in the position of center line of lower seat board and spherical bearing
Position pin.Realize bearing fixed effect.
Compared with existing spherical bearing, particularly advantage of the invention is：Beam bottom longitudinal slope error can be adapted to automatically, save beam
Wedge shape levelling steel plate rolled steel dosage in bottom can easily realize that horizontal sliding surface is horizontal, facilitate bridge maintaining and maintenance, to real
It is existing bridge structure safe, durable.
