In general, the bridge device is a device that transmits the impact load and the like acting on the upper portion of the bridge to the lower structure and absorbs the impact, it is a structurally important element in the durability and safety of the entire bridge structure.

Such a bridge device is implemented by various devices and methods, and recently, the seismic function of the bridge is statically absorbed by static displacement of the relative displacement due to temperature change, wind, support, etc. In order to further extend the service life, a spherical bridge device is installed between the bridge deck and the bridge.

Looking at the repair work or construction order of the chair apparatus, first set the jack (JACK) installation place and then raise the bridge through the jack and then dismantle the existing chair apparatus. Then, perform the work of breaking the shrinkage mortar, and then replace the new bridge and perform the reinforcement and the shrinkage mortar casting and curing process, and then cut down the bridge and remove the jacks installed continuously. do.

Since such work is mainly constructed in a narrow space and is in common, there are many constraints such as work to be performed in a short time. Therefore, it is pointed out that a reliable and safe maintenance method should be presented.

In addition, the above-described spherical type bridge device has been filed and registered as Utility Model Registration No. 20-0398506, "Spherical bridge bridge device".

It has been suggested that a spherical bearing having a rubber pad including a fluorine resin plate installed on the upper surface of the bearing plate is installed by a bolt that is a fixing member between the lower answer to be embedded in the piers and the upper answer to which the upper plate is placed.

That is, a spherical recess 12 in which a spherical surface of a bearing plate is rolling is formed on a protrusion protruding upward from FIG. 1 or 2, and a lower stopper having side blocks 14 installed on both sides thereof.
