New Bridges upper and lower welding installations



 

Sliding Elastomeric Bridge Bearing is a basic buffing material that absorbs and blocks the noise, vibration and shock to the structure. The coefficient of friction for the displacement of upper plate due to the temperature contraction, dry contraction and warping and for the rotary movement generated from the entering vehicles' weight is minimized. And it is designed and developed to accommodate displacement and deformation generated horizontally.
As a method of shutting off the heat delivered from the outside and upper/lower part of shoe plate, it is aiming to lengthen the life and elasticity of the elastomeric bearing. 4 exposing faces of the elastomeric bearing is coated with special liquid fluorine rubber. And the hardening and aging phenomena of the elastomeric bearing due to the air temperature, air contact, acid rain, etc. are minimized.

Product Description:
































The Sliding Elastomeric Bridge Bearing, a material for bridge structure, was developed to minimize the deformation of bridge structure with methods such as air cooled GT, sheet to block the high temperature, heat isolation punching, EM sheet, etc. to upper/lower steel plates of bridge bearing and to maintain and lengthen the elasticity through preventing deformation and displacement such as hardening, aging, isolation of steel plate from rubber, etc. caused by continued solar heat, welding heat, air temperature, air contact, etc. on the upper steel plate basically.
This is completely different buffer device from metal disc bearing. The sliding method is applied to minimize the frictional coefficient due to temperature contraction, dry contraction and rotating displacement due to the entering vehicles' weight.


When applying vertical load that can accommodate deformation and displacement such as horizontal/vertical load of the upper/lower bridge structureearthquake, vibration, moment, etc. to elastomeric bearing with compression function, then there occurs expansion phenomenon toward both sides along with compression deformation. Reinforced bearing restrains deformation of rubber and increase the resistance force also supports vertical load and reduce the expansion capacity.





l Special Features of Sliding Elastomeric Bridge Bearing l




 

Bridge bearing is good for bridge structure as a buffer device.
But it might not work as a structure bearing because of the many sided displacement and deformation arising from upper structure through the deformation due to the nature of rubber such as hardening, aging, isolation of steel plate from rubber, etc. caused by the heat delivered from the outside such as installation method, environmental condition, continued solar heat, welding heat, air temperature, air contact, etc. And the separation of the elastomeric bearing may occurs due to the loss of elasticity caused by hardening through the external heat.




The Sliding Elastomeric Bridge Bearing adopts the method of shutting off the heat basically delivered from the outside and is aiming at lengthening and maintaining of elasticity in order to smoothly accommodate the displacement such as vertical/horizontal load, active load, impact, rotation, seismic resistance, seismic isolation of bridge structure.

 

 

Thermal Shut-off System Applied to Elastomeric Bearing

Because of the physical nature of Synthetic Rubber (Neoprene) which is chloroprene polymer, various incidents such as hardening, aging, isolation of steel plate from rubber, etc. occur through the contact of external heat.
