SCAFFOLD PLATE WITH HATCH
To close a hatch opening with a hatch lid even when a ladder is leaned on an auxiliary opening.SOLUTION: A scaffold frame 5 is formed by connecting both ends of a pair of parallel main frames 3 with an auxiliary frame 4, a floor plate 6 is arranged in the scaffold frame 5, a hatch opening P penetrating vertically is formed, and a hatch lid 7 for opening and closing the hatch opening P is pivotally supported on the main frame 3. An auxiliary opening S into which a ladder H can be inserted is formed in the extension part of the hatch opening P, a hatch auxiliary lid 8 for opening and closing the auxiliary opening S is arranged in the extension part of the hatch lid 7, and the hatch auxiliary lid 8 is pivotally supported on the hatch lid 7.SELECTED DRAWING: Figure 1
【課題】 補助開口に梯子を立て掛けていても、ハッチ蓋でハッチ開口を閉鎖できるようにする。【解決手段】 平行な一対の主フレーム３の両端間を補助フレーム４で連結して足場枠５を形成し、この足場枠５内に床板６を配置するとともに上下に貫通するハッチ開口Ｐを形成し、このハッチ開口Ｐを開閉するハッチ蓋７を主フレーム３に枢支している。前記ハッチ開口Ｐの延長部分に梯子Ｈを挿入可能な補助開口Ｓを形成しており、前記ハッチ蓋７の延長部分に前記補助開口Ｓを開閉するハッチ補助蓋８を配置し、このハッチ補助蓋８をハッチ蓋７に枢支している。【選択図】図１
