It is spherical bearing), construction quality is easily guaranteed that, has also further ensured the service performance of support.
3 are additionally arranged horizontal level meter in undersetting steel plate both direction, to guarantee horizontal sliding surface level, also facilitate
Construction and later period 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 two sides plate washer, Gu
Determine support and is changed to central spacer pin.
Novel monodisplacement support 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 support length travel had been met, and had had and meet support cross spacing.
Novel hold-down support processes circular hole in the position of center line of lower seat board and spherical bearing, setting is fixed in hole by Fig. 2
Position pin.Realize support fixed effect.
Compared with existing spherical bearing, the specific advantage of the utility model is: can adapt to beam bottom longitudinal slope error, section automatically
The levelling steel plate rolled steel dosage of beam bottom wedge shape is saved, can easily realize that horizontal sliding surface is horizontal, facilitate bridge maintaining and maintenance, from
And realize bridge structure safe, durable.
