Zusammenfassung:	The utility model relates to the technical field of stainless steel stairs, in particular to a steel structure stair prestress zipper mechanism which comprises a stand column, a pull rod, a sleeve rod and a corrugated waterproof pipe, the stainless steel stairs are installed on one side of the stand column, a threaded rod is rotationally connected into the stand column, and an installation block is connected to the threaded rod through a threaded sleeve. The mounting block is slidably connected to the side wall of one end of the stand column. By rotating a screwing cap, the positions of a threaded sleeve and a mounting block are adjusted, then the fixing positions of a pull rod and a sleeve rod are changed, the fixing positions of the pull rod and the sleeve rod can be adjusted, the pull rod and the sleeve rod can fix and connect the two stand columns more stably, and therefore the fixing stability of the stainless steel stair is improved; and the side wall of the inner end of the sleeve rod is tightly sleeve
