The invention relates to a butterfly buckle combined type scaffold device. The device comprises a vertical rod, a cross rod, a butterfly buckle socket and a plug and is characterized in that the butterfly buckle socket is formed by four symmetric elliptic arc butterfly buckles, the width H of each butterfly buckle is 50 mm, a groove type plug and jacket structure is arranged in each butterfly buckle, and the diameter of an inner hole in the center of the butterfly buckle socket is 52 mm; the lower surface of the plug is conical, and slots are formed in two side surfaces of the bottom of the plug. The butterfly buckle combined type scaffold device is reasonable in structure design, safe, convenient and rapid to use, easy to transport and store and simple to maintain, no special locking parts are used on a steel pipe scaffold in structure, the locking reliability is improved, the problem of high probability of losing and damage of movable parts of a conventional scaffold is solved, and the scaffold device is more safely erected and dismounted and can be widely applied to civil engineering and construction.
