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

1. Upper Bearing Plate : Connects to the beam to transfer loads.
2. Stainless Steel Sliding Plate (movable bearing): Provides a sliding surface to accommodate displacement.
3. Polytetrafluoroethylene (PTFE) Sliding Plate : Reduces friction coefficient, Contact me for a quote on GPZ(2019)5.0ZX and 5HX pot bridge bearings facilitating sliding.
4. Intermediate Steel Liner Plate : Bears pressure and transfers loads.
5. Rubber Sealing Ring : Prevents dust and moisture ingress, extending service life.
6. Lower Bearing Plate : Connects to the bridge pier or abutment.

3. Main Types

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).
