Abstract

PURPOSE:To provide an elevator installation scaffolding device which can be temporarily erected with no working required for a ceiling of a station. CONSTITUTION:A fixture 6 is mounted in a floor 3 of a station 2 by downward direction work in the station 2, and a supporting fixture 10 is mounted in an edge part of a gate 4 of the landing 2 by sideward direction work in the station 2. A scaffolding arm 8 is horizontally arranged through the fixture 6 and the supporting fixture 10, and a protrusively provided end of the scaffolding arm 8 is connected to the supporting fixture 10 by a connecting bar 14. Through the scaffolding arm 8 thus mounted, weight lifting work for installation and centering for installation work are performed. In this way, the scaffolding arm can be mounted without fastening the supporting fixture to a ceiling of the station by an anchor bolt or the like, and necessity for upward direction work is eliminated, to faciltate work for mounting the scaffolding arm.
