The utility model relates to a stepping formwork and a stair formwork structure formed by the stepping formwork. The step template comprises two step template units which are spliced with each other,a splicing plate is formed at one end of each step template unit; the two step template units are detachably and fixedly connected through the splicing plate; each stepping formwork unit comprises a transversely-arranged pedal and a kickplate vertically connected to the pedal. A bottom connecting plate detachably fixed with the top of another adjacent step template is formed on the edge of the pedal; a top connecting plate detachably fixed with the bottom of the adjacent step template is formed at the top of the kickplate; the step formwork units can be prevented from colliding with a wall body, disassembly is convenient, and the problems that in the prior art, due to the fact that the wall bodies are formed on the two opposite end sides of the step formwork, the formwork disassembly operation space is narrow, the whole step formwork is prone to colliding with and damaging the wall bodies when being directly lifted upwards for formwork disassembly, disassembly is inconvenient, and efficiency is low are solved.
