〓 PRODUCT OVERVIEW
It is composed of a steel basin, a rubber seal and a PTFE slide plate, and is suitable for load transfer and multi-directional displacement adjustment of large-span bridges.
〓 STRUCTURAL FEATURES
Multi-layer composite structure: rubber layers (NR/CR) and Q235/Q345 steel plates are alternately stacked and vulcanized.
Elasticity and shear deformation: shear deformation can reach ±50mm, and rotation angle ≤0.01rad.
〓 FUNCTION AND PERFORMANCE
Function | Parameter |
Vertical bearing capacity | 500kN~5,000kN (according to GB/T 20688.2 standard) |
Horizontal displacement capability | ±5~50mm (positively correlated with the thickness of the rubber layer) |
Rotation Angle | 0.01rad |
〓 APPLICATION SCENARIOS
Bridge types: simply supported beam bridge, continuous beam bridge (span ≤ 40m).
Engineering scenarios: small and medium span structures such as urban elevated roads and highway bridges.
〓 INSTALLATION POINTS
Surface treatment: The flatness of the top surface of the pier is ≤ 2mm/m², and a 1:3 cement mortar leveling layer is laid.
Limit control: The gap of the lateral limit device is ≤ 3mm to prevent the bearing from slipping.
Direction control: The long side is parallel to the direction of the bridge expansion joint, and the longitudinal slope is allowed to be ≤ 2%.
