MOVEMENT RESTRICTION DEVICE
PROBLEM TO BE SOLVED: To provide a movement restriction device capable of reducing a cost without need of using a columnar steel material having an excessive dimension.SOLUTION: A movement restriction device 100 restricts movement of a bridge girder 50 installed on a lower structure to prevent the bridge girder from dropping out to the right or left. The movement restriction device 100 includes a long steel material 170 whose longer direction is in parallel with the bridge girder 50's movement direction. Extension of the long steel material 170 in the longer direction following the bridge girder 50's movement absorbs energy of the bridge girder 50 starting to move, and restricts the bridge girder 50's movement. One end of the long steel material 170 is attached to a fixed block 110 fixed on the lower structure; the other end of the long steel material 170 is attached to the bridge girder 50.SELECTED DRAWING: Figure 1
【課題】過大な寸法の柱状鋼材を利用する必要がなく、コストを低減することが可能な移動制限装置を提供する。【解決手段】本発明に係る移動制限装置１００は、下部構造物上に設置される橋桁５０の移動を制限し、前記橋桁が前記下部構造物の左右に脱落しないようにする移動制限装置１００において、前記橋桁５０の移動方向と、長手方向が平行である長尺鋼材１７０を設け、前記橋桁５０の移動に伴い、前記長尺鋼材１７０が前記長手方向に伸びることで、前記橋桁５０が移動しようとするエネルギーを吸収し、前記橋桁５０の移動を制限し、前記長尺鋼材１７０の一端が、前記下部構造物上に固定されている固定ブロック１１０に取り付けられ、前記長尺鋼材１７０の他端が、前記橋桁５０に取り付けられることを特徴とする。【選択図】 図１
