Almost every highway and bridge in Chinais using ourPlateTypeRubber bridge bearing.

GJZ SeriesPlateTypeRubber bridge bearing:
GJZ SeriesPlateTypeRubber bridge bearing is made up of several layers of rubber strips and thin steel plates which are pressurized and sulfurized. ThePlateTypeRubber bridge bearing has sufficient vertical rigidity to deal with the vertical loads. Meanwhile, it also shows excellent elasticity to accommodate for rotation of the beam end. ThePlateTypeRubber bridge bearing allows for comparatively large shearing deformation to adapt to horizontal displacement of the upper structure; the excellent shock-absorbing performance of thePlateTypeRubber bridge bearing may reduce the impact of live loads on the upper structure and the pier. Other features of thePlateTypeRubber bridge bearing include simplified construction, easy installation, inexpensiveness, easy maintenance and replacement

GJZF4SeriesPlateTypeRubber bridge bearing:
GJZF4 Series Plate Type Rubber bridge bearing is covered with a layer of 2~4mmthick PTFE (F4) board on the basis of GJZ seriesPlateTypeRubber bridge bearing according to the bearing plane dimension. Other than functions of GJZ bearings, the horizontal displacement of its upper structure is not restrained by the shearing deformation of the Plate Type Rubber bridge bearing itself due to the low friction coefficient between the F4 board and the stainless steel plate at beam bottom, thus, reducing the shearing force. Meanwhile,Plate TypeRubber bridge bearing can also be used to move heavy object by sliding.
