CONCRETE MEMBER FALL PREVENTION DEVICE AND FALL PREVENTION METHOD
To provide concrete member fall prevention device and fall prevention method, for preventing a PCa segment T girder from falling to enable safe conveyance, building, or the like of the PCa segment T girder.SOLUTION: A concrete member fall prevention device is constituted by: a fall prevention support 2 that is to be erected at a side of a main girder part A1 of a PCa segment T girder A to support a flange part A2 of the PCa segment T girder A upward; and a fixation bracket 3 that is to be fitted on a side surface part of the main girder part A1 to fix the fall prevention support 2 at the side of the main girder part A1. The fall prevention support 2 comprises a height adjustment jack 4. The fixation bracket 3 comprises an arm part 7 for connecting the fixation bracket 3 with the fall prevention support 2. The arm part 7 is installed so as to be capable of being stored on the side surface part of the main girder part A1 by horizontally revolving on the main girder part A1 side.SELECTED DRAWING: Figure 1
【課題】PCaセグメントＴ桁の転倒を防止して、PCaセグメントＴ桁の運搬や架設等を安全に実施できるようにしたコンクリート部材の転倒防止装置及び転倒防止方法を提供する。【解決手段】PCaセグメントＴ桁Aの主桁部A1の側部に立設され、PCaセグメントＴ桁Aのフランジ部A2を上方に支持する転倒防止サポート2と、主桁部A1の側面部に取り付けられ、転倒防止サポート2を主桁部A1の側部に固定する固定ブラケット3とから構成する。転倒防止サポート2は高さ調整ジャッキ4を備え、固定ブラケット3は、固定ブラケット3と転倒防止サポート2とを連結するアーム部7を備え、アーム部7は主桁部A1側を軸に水平に旋回して主桁部A1の側面部に格納可能に設置する。【選択図】図１
