Socket disc buckle type scaffold supporting device suitable for high and large formwork

The utility model discloses a socket disc buckle type scaffold supporting device suitable for a high and large formwork, and solves the problems that when the socket disc buckle type scaffold supporting device is used, the installation position of a transverse rod cannot be stabilized, so that time and labor are wasted in connection between a vertical rod and the transverse rod, and the position for installing a scaffold is inclined. Comprising a vertical rod, a cross rod and a base, the vertical rod and the cross rod are connected through a disc, a mounting pipe is fixedly mounted at the upper end of the base, and when the scaffold supporting device is used and the internal vertical rod and the cross rod are mounted, the mounting positions of the vertical rod can be kept in the same line through connection between an internal sliding block and a sliding groove; according to the scaffold convenient to install, the position of the disc is kept straight, when the transverse rods are installed, the transverse ro
