Q:Can you describe about the definition of rubber bearings?
---&©|160;Rubber bearing is&©|160;the supporting parts to support containers and equipment weight, and fixed on the position, but also bear the operation of vibration and seismic loads. Rubber bearings are made of rubber and thin steel sheets and used for supporting the weight of the bridge.&©|160;

Q:Please describe the characteristic about the PTEF plate rubber bearing for me.
--- This product is in ordinary laminated rubber bearings on the bonding of a thick layer of 1.5-3mm Teflon plate. In addition to &©|160;vertical stiffness and elastic deformation&©|160;of ordinary laminated rubber bearing, it afford to vertical load and adapt to the rotation of the beam end, Because of tetrafluoroethylene and low coefficient of friction between the beam bottom of stainless steel plate (mu 0.08 or less) ,it can make the horizontal displacement of the bridge superstructure is not restricted.&©|160;

Q: What are the installation ***ails of the&©|160;rubber bearing ?
1.When using this series of bearings, the bridge girder and bridge pier, the pier bearing part of the concrete grade shall not be less than 300&©|160;grade. Special circumstances shall be subject to the consent of the design unit.
2.Bearing and girder and piers, the pre buried bolt connection, when necessary it can also be with pre embedded steel plate welded connections, but when the bearing and girder and pier pre buried steel plate are welded to prevent overheating of bearing steel body, to avoid burning the silicone and PTFE plate.
3.Bearing installation elevation should meet the design requirements, to ensure that the bearing surface is aclinic and smooth, the bearing surface four angles of elevation shall not be greater than 2mm.
4.After bearing approach, check the packing list, including parts list, bearing products certificate, bearing installation and maintenance rules.
5.Bearing installation should pay attention |
