In general, a bridge support applied to a bridge is a device that is installed between an upper structure (upper plate) and a pier (or alternation) in a bridge and transfers the movement amount and load of the upper plate to the lower structure. .

Such bridge supports absorb various relative displacements due to impacts such as temperature changes, wind, and earthquakes, or horizontal forces of the bridge tops, to smooth the seismic function of the bridge, and to extend the durability of the bridge.

The upper plate is supported on the upper surface of the bridge, the lower plate is supported on the upper surface of the bridge, the support is positioned between the upper and lower plates, and the screw is coupled to the anchor socket on the top surface of the bridge through the lower plate And anchor bolts for controlling the fixing and horizontal force.

The upper plate is positioned in such a manner that an anchor socket is inserted into an insertion hole formed in an upper portion of a bridge pier. At this time, there is a problem that the upper plate is difficult to be leveled due to irregularly cast iron bars.

In order to overcome such a problem, conventionally, the vertical plate is leveled by deforming or breaking with a force of a cast iron which interferes with the horizontal. Such a method does not only cause a serious problem that hinders the most important safety in the bridge, There is a problem that the period is increased and the cost is increased.

On the other hand, the negative reaction force refers to the force that the bridge top plate can hear due to the load of the vehicle moving in the bridge, which is directly related to the safety of the bridge. Conventionally, a method of additionally installing a negative reaction force prevention device has been used. Therefore, there is a disadvantage that costs are incurred to further increase the overall construction cost of the bridge.
