向上が図れることになる。As described above, according to the present invention, the flange member fixed to the outer periphery of the steel pipe is provided with a hole for coupling, and the holder member fixed to the end of the steel pipe is provided with a thickness corresponding to the thickness of the flange member. By providing a notch for external fitting and inserting the coupling member inserted into the coupling hole of the flange member in the holder member, by inserting the coupling member into the coupling hole,
Since the front end wall of the holder member is sandwiched between the outer peripheral surface of the steel pipe and the outer peripheral surface of the steel pipe, the connecting member can be held in the holder member. The overall shape can be made compact by storing the connecting member in the holder member, and when a work scaffold or support is constructed, the scaffold plate can be arranged so as to cover the holder member, and the work scaffold In addition, the generation of a gap between the side surface of the shoring and the side edge of the scaffolding plate is reduced, and safety can be improved.

ることができる。Further, the connection can be released only by knocking up the connecting member, so that the scaffolding and the shoring can be dismantled with one hand, and the safety at the time of work can be ensured. Since the connecting hole provided in the member is formed in a fan shape, the other steel pipe can be connected to one steel pipe at an angle, and a support and a scaffold that can correspond to a curved shape can be constructed.
