PERMANENT SCAFFOLDING INSTALLATION METHOD AND BRIDGE ACCESSORY INSTALLATION METHOD
To provide a permanent scaffolding installation method and a bridge accessory installation method that enable the shortening of a construction period for installing a permanent scaffold or a bridge accessory in a place having a construction limit.SOLUTION: An installation method for installing a permanent scaffolding under a bridge includes the steps of: installing a skeleton 20 of a permanent scaffolding 11 at a first height outside a construction limit 10 with a suspension member 21 connecting arm members 7, 6a, 6b and 4b of bridge girders 2a to 2c and the skeleton 20; and lowering the skeleton 20 from the first height outside the construction limit 10 to a second height with a chain block and installing the skeleton 20 at the second height with the suspension member 21. The skeleton 20 is lowered from the first height to the second height while aligned with respect to the girders 2a to 2c by the suspension member 21.SELECTED DRAWING: Figure 1
【課題】建築限界が存在する場所において、恒久足場や橋梁付属物を設置するための工期短縮を可能とした恒久足場設置方法および橋梁付属物設置方法を提供する。【解決手段】橋梁下に恒久足場を設置する設置方法であって、建築限界１０外において、恒久足場１１の骨組み２０を、橋梁の桁２ａ〜２ｃが有する腕材７，６ａ，６ｂ，４ｂと骨組み２０とを接続する吊材２１で第１高さに設置する工程と、建築限界１０外において、骨組み２０を第１高さから第２高さまでチェンブロックで降下し、吊材２１で骨組み２０を第２高さに設置する工程とを備え、骨組み２０が吊材２１によって桁２ａ〜２ｃに対して位置合わせがされた状態で第１高さから第２高さへ降下される。【選択図】図１
