TEMPORARY STAIRCASE SCAFFOLD
PROBLEM TO BE SOLVED: To form a horizontal work floor by a temporary staircase scaffold, which has a high workability and enables installation work, demolition work and removal work of the temporary stair scaffold to be simplified or omitted 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) or a horizontal beam and joist (4'), which is supported by a support part (70) of the brace; a horizontal member (3), which is disposed between the braces on both sides of the staircase and 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 scaffold board is supported by the stepped oblique joist or the horizontal beam and joist. A staircase work floor or an entirely horizontal work floor, which extends below a ceiling structure or the ceiling face (C), is formed in an upper space of the staircase.SELECTED DRAWING: Figure 7
【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・撤去作業を簡素化し又は省略可能にするとともに、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、支柱の支承部（70）に支承され、桁方向に延びる段付き斜行梁(4)又は水平桁梁(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。足場板は、段付き斜行梁又は水平桁梁に支承され、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又は全体的に水平な作業床を階段の上部空間に形成する。【選択図】図７
