Application

The GQZ range of bridge spherical bearings demonstrates particularly evident advantages in bridges with complex stress conditions, such as curved bridges, skew bridges, wide bridges, long-span continuous beam bridges, and rigid frame bridges .

Features

Adopting a spherical contact design, it ensures smooth force flow, effectively avoiding stress concentration and achieving uniform distribution of reaction forces in the substructure. With a fine grading of vertical bearing capacities and a wide coverage range (typically from 1000kN to 60000kN), it can meet the needs of structures ranging from small and medium-sized bridges to long-span structures

Parameters

1. Load Capacity

1000kN to 60000kN (vertical force)

2. Horizontal Capacity

Typically designed for 10% of the vertical bearing capacity (for fixed and guided /unidirectional movable types):

3. Rotation Angle: 

Standard design rotation is generally≥0.02rad to 0.05rad（approx. 1.15°to 2.86°）allowing universal multi-directional rotation.

4. Applicable range of support temperature:

Normal temperature type: -25℃ ~ +60℃; Cold resistant type is -40℃ ~ -25℃.

5. Friction coefficient

Normal temperatures(-25℃ ~ +60℃): ≤0.03; Low temperatures(-40℃ ~-25℃): ≤0.05.
