「産業上の利用分野」
本考案は、鉄骨造階段室の段裏及び壁上部の仕
上げ用足場として使用する階段用吊足場に係るも
のである。[Detailed description of the invention] "Industrial Application Field" The present invention relates to a hanging scaffold for stairs that is used as a finishing scaffold for the back of steps and the upper part of walls of a steel-framed staircase.
「従来の技術と考案が解決しようとする問題点」
鉄骨造の建物における階段室は、狭く、かつ、
形状が特殊なため、通常の踏面を反力とした足場

用の吊足場が提案されている(実開昭60−190341
号公報)。``Problems that conventional technology and ideas are trying to solve'' Staircases in steel-framed buildings are narrow and
Due to the special shape of the scaffold, erecting a scaffold that uses normal treads as a reaction force would cause an obstruction to traffic, so a special suspended scaffold has been proposed (Utility Model 1983-190341)
Publication No.).
