The invention relates to a steel pipe scaffold fastener. The technical scheme which is adopted by the invention for solving the technical problem lies in that the steel pipe scaffold fastener is a cross-shaped base integrally cast by malleable iron, a T-shaped tightening latch is loaded in a cast groove formed in the upper part of the cross-shaped base, a sleeve nut is screwed in the right end of the tightening latch, the right end of the sleeve nut and an eccentric wheel pressing rod are movably riveted together by using a rivet, a rolling edge is cast at the lower part of the cross-shaped base, the rolling edge and an opening slot formed in the lower part of a cover tile are movably riveted together by using a rivet, another opening slot is formed in the upper part of the cover tile, a circular arc matched with the eccentric wheel pressing rod is cast at the right end of the opening slot in the upper part of the cover tile, and an eccentric wheel and a pressing rod are cast into one body. When the steel pipe scaffold fastener is used, scaffold steel pipes are placed in the semi-circular arc part of the cross-shaped base, and then the cover tile is closed, the T-shaped tightening latch is screwed in the sleeve nut, the right end of the sleeve nut and the eccentric wheel pressing rod are movably riveted and clamped in the upper opening slot of the cover tile, the eccentric wheel is in the circular arc of the right end of the cover tile, and the eccentric wheel pressing rod is pressed to complete a fastening task. The eccentric wheel pressing rod is pried up when a steel pipe scaffold is disassembled, the cover tile and the cross-shaped base are separated from steel pipes, and the assembly and disassembly are quick and convenient.
