Expansion Joints:

Expansion joints undertake the task of providing transition in bridge openings and pedestrian openings. It is necessary to make all kinds of movements without creating any restrictive force. Additionally, expansion joints should provide traffic safety and waterproofing on the bridge surface.

Modern bridge construction techniques require to meet traffic density, vehicle load and driving comfort increased due to large expansion and shrinking movements.

Bridge Bearings:

Bridge bearings undertake the task of transferring dead loads, moving loads, brake loads and wind loads to bridge piers. They should be designed to meet movements and rotations arising from traffic, heat exchange, earthquake, creep and shrinkage effects. Therefore, the bearings are among the most important elements in the bridge body and require high quality standards.

• Pot Bearings:
  The rubber disc surrounded by the steel bowl allows for sliding movements in all horizontal axes through the deformation capacity.
• Spherical Bearings:
  The spherical bearings transfer the vertical loads to the bridge structure and absorb the rotational movements through the spherical surface and the concave bottom steel element.
