Product Description

Pot Bearing with Large Load Capacity and Large Horizontal Displacement
    Pot bearing is a kind of new type bearing which is composed of pot, elastomeric pad, stainless steel plate, sealing ring and other components. It is designed for bearing the combinations of vertical loads, horizontal loads, longitudinal and transverse displacements and rotations. Pot bearing is ideal bearing for large bridge with the features of large horizontal displacement, light weight, simple structure and easy operation.

Construction

The installation of bearings mainly includes the following steps:

1.Foundation Inspection and Cleaning: Check whether the foundation at the bearing installation location is flat and solid, in accordance with the design requirements. Remove debris, dust, and oil stains from the foundation surface to ensure that the foundation is clean and dry.

2.Bearing Positioning and Installation: According to the design drawings, accurately determine the installation position of the bearing and use measuring tools for positioning. Place the bearing at the predetermined position and adjust the levelness and elevation of the bearing to meet the design requirements.

3.Fixing and Connection: Use bolts, welding, or other methods to firmly connect the bearing to the foundation. For bearings with anchor bolts, pass the anchor bolts through the reserved holes in the bearing and tighten the nuts to ensure a tight connection between the bearing and the foundation.

4.Inspection and Acceptance: After the installation is completed, conduct a comprehensive quality check of the bearing installation, including the levelness, elevation, and positional deviations of the bearing. Ensure that all indicators meet the design and specification requirements. Only after passing the inspection can the subsequent construction processes proceed.
