Qpz bridge pot bearing is a new type of innovative bearing with unique advantages. Its movable bearing adopts a middle oriented structure, which can ensure that the beam end rotates in the plane through the rotation of the middle steel lining plate,
It solves the torsion of the pier and abutment caused by the lateral bending deformation of the beam caused by sunlight, so the bearing will not restrict the beam and abutment, and the structural size of the bearing is reduced,
This series of bearings are widely used in all kinds of highway and railway bridges, especially for curved bridges and wide bridges with large side bend.

Structure
Construction and installation points
Before sending bearings to sites, check whether the bearings are in good condition, whether the parts are complete and whether the report is available (documents include shipping list, certificate of conformity and copies of qualified test report of raw materials of bearings when required by customers)
Remove the connecting bolts of the upper base plate and the lower base plate, uncover the upper base plate, clean the relative sliding surface with alcohol or acetone, wipe it dry, and coat the groove of F4 plate with 295 silicone grease.
It is recommended to use positioning bolts to connect the support, beam body, pier and abutment, and welding connection is not allowed
Support pad stone concrete shall not be lower than grade C40
The installation elevation of the support shall meet the design requirements, the support plane must be horizontal, and the height difference of the four corners shall not be greater than 2mm
The center line of the support shall be parallel to the center line of the main beam. The center lines of the upper and lower support plates of the movable support along the bridge shall coincide, and the deviation intersection angle shall not be greater than 5 °
