To reduce the time and labor required to install a ladder.SOLUTION: In a ladder 1 for use in a vertical shaft, multiple ladder members 7, including two supports 5 arranged in the vertical direction and a plurality of steps 6 installed at an appropriate interval in the vertical direction between the supports 5, are arranged continuously in the vertical direction in a vertical shaft 3 in which a liner plate 2 is installed on a shaft wall. Each of the ladder members 7 has a bent portion at the upper end of a portion extending upward from the supports 5, and is provided with a hook portion 11 which allows the ladder members 7 to be connected in the vertical direction by hooking the bent portion to the lowermost step 6 of the ladder member 7 on the upper stage side, and is also provided with a mounting fitting 12 which extends from the supports 5 to the liner plate 2 side and has at the tip thereof a fixing portion 13 which can be fixed to a connecting bolt 2a of the liner plate 2.SELECTED DRAWING: Figure 1
【課題】はしごの設置作業にかかる時間と労力を軽減する。【解決手段】立坑内はしご１は、坑壁にライナープレート２が設置された立坑３内に、上下方向に沿って配置された２本の支柱５と、前記支柱５間に上下方向に適宜の間隔で架設された複数のステップ６とを備えたはしご部材７が、上下方向に複数連続して配置されている。前記はしご部材７は、前記支柱５より上方に延びる部分の上端部に屈曲部を有し、この屈曲部を上段側のはしご部材７の最下段のステップ６に掛止することにより、前記はしご部材７が上下方向に連結可能とされるフック部１１を備えるとともに、前記支柱５から前記ライナープレート２側に延び、先端に前記ライナープレート２の連結ボルト２ａに固定可能な固定部１３が形成された取付金具１２を備えている。【選択図】図１
