I claim:

1. A scafl'old construction comprising two spaced pairs of rigid hangers, each of said hangers comprising a vertically disposed angle-iron support, a hook member fixedly secured to the upper end of said angle-iron support and having its hookedend extending downwardly and outwardly on an angle to the longitudinal axis'of said support, said angle-iron support having its flanges provided with a series of vertically spaced holes, a lug removably secured to said support by bolts mounted in selected ones of said holes, said lug extending parallel with said support and having its upper end spaced from said support, a horizontal bar bridging the space between and connecting the hangers of each of said pairs of hangers, said bar being mounted in the spaces between said lugs and said supports, said bars being provided with a plurality of spaced apertures adjacent each end, pins mounted in selected ones of said apertures in said bars at each side of said lugs to prevent longitudinal movement of said bars relative to said lugs, and planking bridging the space between said pairs of hangers and supported on said horizontal bars. 7 1
