Cast Steel Bearings as a main support for bridges, to simulate the hinge and roller, provide a strong vertical loading support and horizontal loading / displacement bearing. The main steel material meets the requirement of SCW480 specification.
An expansion joint or movement joint is an assembly designed to safely absorb the heat-induced expansion and contraction of various construction materials, to absorb vibration, to hold certain parts together, or to allow movement due to ground settlement or earthquakes.
Lead rubber bearing as a laminated bearing manufactured from layers of rubber, bond with layers of steel, and in middle of bearing there will be a solid lead core or cores inserted, which form a bearing with strong vertical stiffness and low horizontal stiffness.
Pot bearing can be identified into three types: fixed bearing, guided bearing and free sliding bearing. It can be equipped for anti-uplifted function, also can be designed to meet sky bridge applied in building or box girder bridge, steel bridge, precasted girder bridge.
With advanced CNC machine center ,CNC lathe and CAD/CAM software, we can carry in great precision mechanic procesing.
Rubber pads are designed for PCI girder especially, It is formed by laminated bearing manufactured from layers of rubber and bond with layers of steel. The rubber pad can take heavy vertical load and accommodate the bearing expansion or shorten due to temperature and live loading.
The Shear Bracket with components of bracket and rubber bearing which provide the horizontal resistance when the bridge is under earthquake. And the rubber bearing provide the damper effect which reduce the impact effect.
The Steel Box Stopper prevents the falling of bridge under seismic. The stopper formed by a steel box install on the pier cap, and the steel box head protrusion into the bottom of box girder.
