Bridge support system applicable to multi-span continuous BEAM bridges
Slide elastic pedestal (E-type elastic pedestal) combined with elastic pedestal and fluororesin plate (P.T.F.E - Polytetrafluorethylene) presented in Korean Industrial Standards (KS F 4420)
Problems with conventional integrated elastic struts (movement amount)
Can not be used on medium/kandai bridges or when the displacement during an earthquake is excessive because the allowable displacement of the elastic base is exceeded.
In the case of high piers, the rigidity of the columns is small and most of the displacement occurs in the columns. If everything must be accommodated by elastic struts, it becomes unstable. Occurs when
sliding elastic bearing
In the drawing direction, the elastic base does not undergo shear deformation and accepts displacement on the sliding surface.
In the direction perpendicular to the transverse axis, the elastic pedestal is designed to undergo shear deformation.
All-in-one elastic bearing (RB_C type)
Integrated elastic pedestal with horizontal force control device using fixing anchor bolts/anchor sockets
One-piece elastic base (C-type elastic base) that combines upper and lower plates and elastic pads, which is presented in Korean Industrial Standards (KS F 4420)
Horizontal force controllable
Problems with conventional integrated elastic struts (anchors)
Anchor bolt/socket size determination for allowable horizontal force during earthquake
Break concrete blocks to remove existing anchors during maintenance
Occurrence of bolt loosening due to vibration of medium, large, and large vehicles from bridges
Integrated elastic receiver with horizontal force control device
Excellent workability and maintainability by minimizing the bolt standard by increasing the ability to control the horizontal force of the anchor bolt/socket.
During maintenance, the lower plate is made of two plates and concrete No cracks and low maintenance costs
Compression springs are applied to the lower plate fixing bolts to prevent loosening of the bolts due to vibration.
