CONSTRUCTION METHOD OF TEMPORARY FALL PREVENTION FENCE AND TEMPORARY FALL PREVENTION FENCE
PROBLEM TO BE SOLVED: To provide a temporary fall prevention fence erectable-fixable in a proper position of an installed U-shaped water passage.SOLUTION: A column 3 is positioned on the tip part side of a horizontal member 2, and fixing means 4 is positioned on the base end part side, and the fixing means 4 is composed of a freely rotatable vertical lever and a freely expandable movable lever for providing a pressure contact plate on the tip of journaling on the left and right of a lower part of the vertical lever, and the pressure contact plate is press-contacted/fixed to left-right inner wall surfaces of a U-shaped water passage by expansively opening the movable lever by rotation of the vertical lever, and the horizontal member 2 and the column 3 are fixed by fixing an upper part of the vertical lever to the base end part side of the horizontal member, and a first skeleton is constructed by the horizontal member 2, the column 3 and the fixing means 4, and a second skeleton is constructed at a predetermined interval in the longitudinal direction of the U-shaped water passage by the horizontal member 2, the column 3 and the fixing means 1 similar to the first skeleton, and fall prevention means 5 is provided between the columns of the first and second skeletons.SELECTED DRAWING: Figure 1
【課題】設置済のＵ字形水路の適宜位置に立設固定することができる仮設用落下防止柵を提供する。【解決手段】水平部材２の先端部側に支柱３、基端部側に固定手段４が位置するようにし、固定手段４は回動自在とした垂直杆と該垂直杆の下方部の左右に軸着してなる先端に圧接板を設けた伸縮自在の可動杆よりなり、該垂直杆の回動により該可動杆を拡開することで圧接板を該Ｕ字形水路の左右の内壁面に圧接固定し、該垂直杆の上方部を該水平部材の基端部側に固定することで水平部材２及び支柱３を固定し、水平部材２、支柱３及び固定手段４により第１骨組を構築し、該第１骨組と同様の水平部材２、支柱３及び固定手段１により第２骨組を該Ｕ字形水路の長手方向に所定間隔を有して構築し、上記第１、第２骨組の支柱間に落下防止手段５を設けてなることを特徴とする。【選択図】図１
