WORK FLOOR FOR SHAFT CONSTRUCTION

To propose a work floor for shaft construction that can shorten the opening and closing time of an equipment loading door and simultaneously achieve fall prevention measures with a simple configuration.SOLUTION: The present invention comprises a stage 2 that can be accommodated in a shaft S, a rectangular opening O in a plan view provided on the stage 2, a set of side plates 3 and 3 having a substantially inverted V shape in a side view erected along one of the opposite edges of the opening O, and a set of lid plates 5 and 5 rotatably installed around the other opposite edge of the opening O. The lid plates 5 and 5 are configured to cover the edges of the side plates 3 and 3 when the opening O is closed.SELECTED DRAWING: Figure 2 【課題】簡易な構成で、機材搬入用扉の開閉時間を短縮し、かつ墜落防止措置を同時に達成できる立坑工事用の作業床を提案すること。【解決手段】立坑Ｓに収容可能なステージ２と、ステージ２に設けられた平面視で矩形形状の開口部Ｏと、開口部Ｏの一方の対向する辺縁に沿って立設された側面視で略逆Ｖ字形状の一組の側板３，３と、開口部Ｏの他方の対向する辺縁を軸に回転自在に設置された一組の蓋板５，５と、を具備し、蓋板５，５は開口部Ｏの閉塞時に側板３，３の辺縁を覆うように構成されたこと。【選択図】図２
