床板工事に於ける鋼棒。[Scope of Claim for Utility Model Registration] Regarding the steel rod used for scaffolding work and concrete thickness measurement in floor board construction, this steel rod 1 is used to support the upper rod 2 that supports the scaffolding board 4 and the girder 6. The upper rod 2 is connected to the lower rod 3 via a threaded joint 8, and can be removed from the lower rod 3 by rotating the upper rod 2. It is made so that it can be removed, and the lower bar 3
is fixed to the girder 6, and the steel rod 1 with the upper and lower rods integrated is erected on the girder, then the scaffold board 4 is placed on the upper rod 2, and in this state, concrete is poured to the extent that the screw joint 8 is buried. After curing, the upper rod 2 is rotated to detach from the threaded joint 8, and the void 18 created by the upper rod detachment is filled with concrete.
A steel rod for use in floorboard work, characterized in that it is subjected to necessary treatment afterwards. The threaded joint 8 includes a male threaded portion 10 formed at the upper end of the lower rod 3 and a connecting nut 11 screwed into the male threaded portion 9 formed at the lower end of the upper rod 2.
A steel rod for use in floorboard work according to claim 1 of the utility model registration claim, characterized in that: The threaded joint 8 includes a male threaded portion 10 formed at the upper end of the lower rod, a connecting nut 11 screwed into the male threaded portion 9 formed at the lower end of the upper rod 2, and a connecting nut 11 screwed into the male threaded portion 9 formed at the lower end of the upper rod 2. A steel rod for use in floorboard construction as claimed in claim 1, which is characterized in that it is constituted by a position fixing nut 21 screwed onto the lower side.
