Vibration isolation module and temporary bridge using of the same

摘要

The present invention can be easily installed in the surface joint portion of the sliding structure to obtain attenuation of the horizontal seismic force, and when the earthquake is extinguished when applied to the temporary bridge, the seismic isolating module and the temporary bridge applying the seismic module are applied. to provide. A seismic isolation module according to a preferred embodiment of the present invention includes a pair of upper and lower sliding brackets that are interviewed so as to be slidably movable with each other; A rolling return device coupled to the upper and lower sliding brackets to return to elastic force when displacement movement occurs and horizontal force is extinguished while resisting elastically when horizontal earthquake force is applied to either side; The rolling return device includes a lock bolt installed vertically through the sliding friction surface of the upper and lower sliding brackets; An upper shiatsu ball inserted into the lock bolt and disposed above the sliding friction surface; A lower acupressure port inserted into the lock bolt and disposed at a lower portion based on a sliding friction surface to face the upper acupressure port; A compression spring inserted into the lock bolt and having one end forcedly compressed in contact with the upper acupressure port or the lower acupressure port; It is characterized in that it comprises a; screw adjustment screw for compression of the compression spring is screwed to the lock bolt.
