SCAFFOLD DEVICE FOR HANDRAIL
PROBLEM TO BE SOLVED: To simplify work for installing a scaffold and removing the scaffold, by comparatively easily forming the scaffold in an outside area of a handrail, without imposing an excessive structural load on a structure for supporting the scaffold and the handrail such as an overpass.SOLUTION: A scaffold device (1) for a handrail comprises a ladder fixing frame (3) installed in an upper end part of the handrail (B) and a lader (2) suspended by the ladder fixing frame and suspended along an outside surface of the handrail. The ladder comprises a protective frame (21) for enclosing a lifting space (J) and a work floor forming member (22) for forming a work floor in a lower part of the lifting space. The protective frame and the work floor forming member are pivotally connected to a column of the ladder so as to be displaced in a storage position of extending along a lifting surface of the ladder by crushing the lifting space.
【課題】足場を支持する構造体や、高架橋等の高欄に過大な構造的負荷を課すことなく、高欄の外側領域に比較的容易に足場を形成するとともに、足場設置及び足場撤去の作業を簡素化する。【解決手段】高欄用足場装置(1)は、高欄(B)の上端部に取付けられる梯子固定枠(3)と、梯子固定枠に懸吊され、高欄の外側面に沿って垂下する梯子(2)とを有する。梯子は、昇降空間(J)を囲む保護枠(21)と、昇降空間の下部に作業床を形成する作業床形成部材(22)とを備える。保護枠及び作業床形成部材は、昇降空間を潰して梯子の昇降面に沿って延びる格納位置に変位するように、梯子の支柱に枢動可能に連結される。【選択図】図４
