1、 Product specification:
1. The vertical bearing capacity is divided into 33 grades: 0.4MN, 0.5MN, 0.6MN, 0.8MN, 1.0MN, 1.5MN, 2.0MN, 2.5MN, 3.0MN, 3.5MN, 4.0MN, 5.0MN, 6.0MN, 7.0MN, 8.0MN, 9.0MN, 10.0MN, 12.5MN, 15.0MN, 17.5MN, 20.0MN, 22.5MN, 25.0MN, 27.5MN, 30.0MN, 32.5MN, 35.0MN, 37.5MN, 40.0MN, 45.0MN, 50.0MN, 55.0MN MN, 60.0MN.
2. Horizontal bearing capacity
The design horizontal bearing capacity of fixed bearings in the non active direction of unidirectional and unidirectional movable bearings is divided into three levels:
JPZ (I) type (ordinary type) - the design horizontal bearing capacity is 10% of the vertical bearing capacity of the bearing;
JPZ (II) (seismic type) - the design horizontal bearing capacity is 15% of the vertical bearing capacity of the bearing;
JPZ (III) type (seismic type) - the design horizontal bearing capacity is 22.5% of the vertical bearing capacity of the bearing.
3. Design angle θ (rad)
The design rotation angle of this series of bearings is not less than ± 0.02rad.
4. Design displacement
The displacement in the transverse direction of the bridge when the one-way movable bearing is horizontally placed in the moving direction and the displacement in the transverse direction of the two-way movable bearing is ± 50mm;
The movement direction of one-way movable bearing and the displacement along the bridge direction of two-way movable bearing are divided into ± 50mm, ± 100mm, ± 150mm, ± 200mm and ± 250mm;
5. Product type: fixed type (GD), one-way movable type (DX), and two-way movable type (SX).
2、 Product advantages:
The structure is novel: the fixed bearing adopts a tenon structure, and the horizontal force can be evenly transmitted to any direction, improving the bearing's mechanical performance;
The one-way movable bearing adopts the middle guide rail structure, with reliable machining accuracy, which improves the sliding guide performance of the bearing;
Excellent material: Q345 hot rolled steel is used as the main steel of the bearing steel plate , improving the overall stress performance of the bearing;
Wear resistant material adopts modified very high molecular weight polymer ethylene , improving the wear resistance, sliding performance and service life of the bearing;
The adoption of high-quality materials effectively reduces the structural size, weight and cost of bearings;
Convenient installation: sleeve and anchor are recommended for support Bolt Connected with piers and beams, it is easy to install and replace.
3、 Application field:
Major highway bridges
