A movable bearing for a temporary bridge and a construction method for the temporary bridge are provided to reduce stress and prevent distortion at a temporary bent part. A movable bearing for a temporary bridge is disposed between an upper beam(11) and a support beam(35) of the temporary bridge that comprises a temporary bent, the support beam, and the upper beam. The temporary bent supports weight of the temporary bridge. The support beam is fixed to an upper part of the temporary bent. The upper beam supports weight of a top plate of the temporary bridge. A construction method for the temporary bridge comprises a lower-bent construction step for temporarily constructing a lower bent, a movable bearing manufacturing and mounting step for manufacturing the movable bearing by using a movable ball(31), an upper beam and fixing end construction step for mounting the upper beam and the support bema, an upper beam separation preventer mounting step for fixing the upper beam, and a deck plate construction step for mounting a concrete deck plate and other deck plates. |
