ABSTRACT OF THE DISCLOSURE The system includes vertical posts with apertured disks secured thereto at intervals, coupling heads, wedge-like keys, scaffold pipes, coupling head extensions, and tang-link heads. Each coupling head has a horizontal slot receiving an apertured disk when the head is pushed into mounted position thereon, and has top and bottom key-receiving openings above and below such slot. A wedge-like key extends down through the top key-receiving opening, through a disk aperture, then through the bottom key- receiving opening, fastening the coupling head to the disk. Coupling heads for horizontal scaffold pipes have extensions insertable into the pipes. Diagonal scaffold pipes have tang- link heads, whose tang has an aperture for a pivot provided on an associated coupling head. Conventionally, the disks, coupling heads and pipes are all made of steel, the disks of 9 mm thickness and 122 mm diameter. The disclosed lighter-weight version employs disks and scaffold pipes made not of steel, but of light metal such as aluminum. The coupling heads although still of steel are differently designed, employing a smaller volume of material and thus lighter in weight. The disks are of 10 mm thickness and 124 mm diameter, producing a 33% loadability increase. Numerous other dimensional and configurational modifications of the standard elements compensate for any structural strength inferiority compared to the standard elements, but the herein disclosed lighter-weight versions thereof remain compatible with, and can be freely intermixed with, the heavier-weight standard elements.
