Scaffold for formwork supporting

The invention relates to the technical field of high and large supporting formwork engineering, and particularly discloses a scaffold for formwork supporting. The scaffold comprises a plurality of rod pieces and a plurality of connecting rod devices. The connecting rod device comprises a first fixing piece, a second fixing piece, an abutting piece and a ring sleeve assembly. And the inner shaft of the second fixing piece is inserted into the shaft barrel of the first fixing piece. The abutment is mounted in the through hole of the shaft barrel wall. The ring sleeve assembly comprises a shell sleeve, a first elastic piece and a pressure applying module. And the shell sleeve is arranged outside the shaft barrel. A first elastic piece, a pressure applying cavity and a loosening cavity are installed between the shell sleeve and the shaft barrel. When the loosening cavity faces the abutting piece, the distance between the first fixing piece and the second fixing piece can be adjusted, and at the moment, the first
