Introduction to GPZ(2019) Pot Bearings
GPZ(2019) Pot Bearings are a type of bridge bearing designed in accordance with the Chinese standard **"Highway Bridge Pot Bearings" (JT/T 391-2019)**, suitable for highway, railway, and municipal bridge engineering. They are primarily used to bear the vertical loads, horizontal displacements, and angular deformations of the superstructure of bridges, Contact me for a quote on GPZ(2019)5.0ZX and 5HX pot bridge bearingsensuring the safety and durability of the bridge structure.
1. Model Meaning
- GPZ : Stands for "Highway Pot Bearing" (Gong Lu Pen Zhi).
- (2019) : Indicates compliance with the latest 2019 standard (JT/T 391-2019).
- Other Parameters (e.g., GPZ(2019) 5DX):
- 5 : Vertical design bearing capacity (5000kN).
- D : Fixed bearing (D represents fixed, H represents unidirectional movement, DX represents bidirectional movement).
- X (optional): Indicates seismic type (with damping function).
2. Main Structural Components
- Upper Bearing Plate : Connects to the beam to transfer loads.
- Stainless Steel Sliding Plate (movable bearing): Provides a sliding surface to accommodate displacement.
- Polytetrafluoroethylene (PTFE) Sliding Plate : Reduces friction coefficient, Contact me for a quote on GPZ(2019)5.0ZX and 5HX pot bridge bearings facilitating sliding.
- Intermediate Steel Liner Plate : Bears pressure and transfers loads.
- Rubber Sealing Ring : Prevents dust and moisture ingress, extending service life.
- Lower Bearing Plate : Connects to the bridge pier or abutment.
3. Main Types
Type | Code | Function |
|---|---|---|
Fixed Bearing | GPZ(2019)D | Allows rotation only, no horizontal displacement |
Unidirectional Movement Bearing | GPZ(2019)H | Allows displacement along the longitudinal direction of the bridge |
Bidirectional Movement Bearing | GPZ(2019)DX | Allows longitudinal and transverse displacement |
Seismic Bearing | GPZ(2019)X | Equipped with damping function, suitable for seismic zones |
4. Main Technical Parameters
- Vertical Bearing Capacity : 1000kN to 60000kN (customizable according to requirements).
- Horizontal Bearing Capacity : Generally 10% to 20% of the vertical bearing capacity.
- Displacement Capacity : ±50mm to ±200mm (movable bearings).
- Rotation Capacity : Typically ≥0.02rad (larger rotations can be customized).
- Friction Coefficient (movable bearings): ≤0.03 (PTFE sliding plate).
- Applicable Temperature Range : -40℃ to +60℃ (customizable for special environments).
