TEMPORARY STAIRCASE SCAFFOLD
PROBLEM TO BE SOLVED: To form a horizontal work floor by a temporary staircase scaffold, which has a high workability and does not require installation work, demolition work and removal work of the temporary stair scaffold on every operation day for repair work and others of staircase ceiling.SOLUTION: A temporary staircase scaffold (1) for constructing a ceiling part (C) of a staircase (S) comprises: multiple braces (2), which are erected on treads of the staircase in a side zone (α) of the staircase; a stepped oblique joist (4), which is installed between the braces and extends in a staircase gradient direction; a horizontal member (3), which extends in a width direction of the staircase; and a scaffold board (5), which is oriented in the width direction of the staircase and forms the work floor. The stepped oblique joist has a scaffold board support body that is made by arranging multiple horizontal parts (43) bearing the scaffold board. The scaffold board is supported by the scaffold board support body. A staircase work floor extending below a ceiling structure or the ceiling face (C) is formed in an upper space of the staircase.SELECTED DRAWING: Figure 3
【課題】階段天井の改修作業等の作業日毎に階段仮設足場の設置作業及び解体・撤去作業を行なう必要性を解消するとともに、作業性が良好な水平作業床を階段仮設足場によって形成する。【解決手段】階段(S)の天井部分(C)の施工のための階段仮設足場(1)は、階段の側部帯域（α）において階段の踏面に立設される複数の支柱(2)と、支柱の間に架設され、階段勾配方向に延びる段付き斜行梁(4)と、階段の両側の支柱の間に架設され、階段の幅方向に延びる横架材(3)と、階段の幅方向に配向され、作業床を形成する足場板(5)とを有する。段付き斜行梁は、足場板を支承する複数の水平部分(43)を階段状に配列してなる足場板支持体を有する。足場板は、足場板支持体に支承され、天井構造体又は天井面(C)の下側に延在する階段状の作業床を階段の上部空間に形成する。【選択図】図３
