このような枠組足場には、作業者の落下防止を図るため、安全設備としての手摺が設けられる。この手摺は、枠組足場の組み立て時には足場の最上段に当たる部分に先行して設置され、枠組足場の解体時には最上段の足場板を取り外すまでは残されるため、先行手摺と呼ばれている。   Such a frame scaffold is provided with a handrail as a safety facility in order to prevent the operator from falling. This handrail is called a leading handrail because it is installed in advance of the portion corresponding to the uppermost stage of the scaffold when assembling the frame scaffold, and remains until the uppermost scaffold plate is removed when the framework scaffold is disassembled.

従来のこの種の先行手摺としては、例えば、特許文献１に開示されているように、縦柱に固定される取付け装置を介して枠組足場に取り付けられる門型又は鳥居型の持ち上がり式先行手すり枠や、非特許文献１に開示されているように、専用金具を使用して支柱を枠組足場の建枠に取り付けた後、その支柱にさらに専用の手すり部材を取り付ける手すり先行足場などが知られている。   As this type of conventional handrail, for example, as disclosed in Patent Document 1, a gate-type or torii-type lift-type handrail that is attached to a frame scaffold via an attachment device fixed to a vertical column. Also, as disclosed in Non-Patent Document 1, there is known a handrail preceding scaffold for attaching a dedicated handrail member to the support after attaching the support to the building frame of the frame scaffold using a dedicated bracket. Yes.
