Description

High damping elasticity support for bridge

The present invention relates to an easy-to-maintain detachable elastic bearing, and in particular, after the separate plate is installed on the upper structure and the lower structure of the bridge, the elastic bearing body is installed to be detachably attached to the plate, thereby making it possible to inspect and replace the equipment. It is easily made, and the binding work with the upper and lower structures and the installation work of the elastic bearing main body are separated, so that when the binding work is carried out on the upper and lower structures, the resin pad is deformed or the separation type can be minimized. It relates to an elastic bearing.

As the number of vehicles increased and the roads expanded, bridges, artificial structures that allowed vehicles to drive over valleys and rivers, were installed all over the road. These bridges are horizontally displaced by vibrations due to earthquakes or movements of vehicles, and contractions, rotations, and expansions occur due to changes in temperature and climate. An elastic support is installed to accommodate the horizontal displacement of the bridge while supporting the vertical load of the bridge.

Such elastic feet are installed between bridges and substructures (including bridges and shifts), and various studies are being conducted to efficiently absorb and alleviate horizontal displacement, contraction, rotation, and expansion of bridges.
