えて、仮設用と最終仕上げのための本設用を明確に区分
し、現場の進捗状況により手摺を取り替えることで対応
している。Conventionally, in consideration of scratches and stains due to collisions of objects during construction work, it is generally clear that the handrails for stairs are for temporary use and for permanent use for final finishing. This is done by dividing and replacing handrails according to the progress of the site.
【0007】この時、本設用手摺の登り桁への取付け
は、その位置関係から、階段の上からの覗き込み作業と
なるが、覗き込み作業では姿勢の悪さから作業能率が上
がらず、また手摺のピッチが細かい場合は作業そのもの
が不可能となる。At this time, the installation of the handrail for main installation to the climbing girder requires a peeping work from the top of the stairs due to its positional relationship, but the peeping work does not improve work efficiency due to poor posture, and If the handrail pitch is small, the work itself becomes impossible.
【0008】また、足場を使用する場合は見上げ作業と

スペースの確保が困難となる場合もある。Further, when the scaffold is used, it is a work of looking up, which is problematic in terms of efficiency, and it costs a lot to assemble and remove the scaffold. Furthermore, when the space between the stairs is small, it may be difficult to secure a working space.

えってコスト高となる可能性がある。On the other hand, in the one disclosed in Japanese Patent Laid-Open No. 2-285144, the handrail used at the time of temporary installation is used as it is for the permanent installation except for the mounting portion, and there is an advantage that the number of temporary materials can be reduced. However, on the other hand, there is a possibility that the handrail, which was originally for permanent installation, must be replaced due to scratches or stains caused by collision of an object during construction work, which may increase the cost.
