A safety device for preventing an I-girder from being turned over is provided to construct conveniently by adjusting length and height according to the size of the I-girder, to increase bearing force by fixing a lower bar with an anchor bolt, and to absorb movement by mounting a movement restricting member. A safety device(900) for preventing overturn includes plural anchor bolts(200) installed in an upper part of pier coping, one set of two lower bars(300) combined with the anchor bolt by a nut(N), a movement restricting member(400) contacted between the lower bar and an I-girder to absorb vibration, an upper bar(500) inserted to an upper part of the lower bar and combined by bolting, and a horizontal bar(600) installed to the upper bar to adjust length. The safety devices are fixed at both sides of the I-girder, and the movement restricting member is contacted and supported between the lower bar and the I-girder. A first pipe(310) of the lower bar is combined with the anchor bolt by the nut, and the first pipes, first and second reinforcing pipes(320,330) for reinforcing the first pipe and first, second and third connecting pipes(340,350,360) horizontally welding the first pipes are integrally fixed to the lower bar by welding. |
