Novel overhanging type scaffold vertical rod limiting device

A novel overhanging type scaffold vertical rod limiting device comprises a vertical limiting steel bar, three bolts and a limiting iron ring. The cross section of the limiting iron ring is square or rectangular; the midpoint positions of the four sides of the limiting iron ring are each provided with a threaded hole. Threads are arranged at one ends of the vertical limiting steel bars; the threaded end of the vertical limiting steel bar is screwed into the threaded hole of the limiting iron ring; and a bolt is screwed into each of the other threaded holes of the limiting iron ring. The I-shaped steel has the beneficial effects that the four sides of the I-shaped steel are fastened through the limiting iron rings, the bolts and the vertical limiting steel bars, the mounting efficiency can be improved while the stability of the structure is effectively guaranteed, and the bolts can be fastened in place at a time; by applying the limiting device, the characteristics of movable adjustment, repeated utilization, e
