<p>A hold cleaning scaffold support device (10) that can be easily attached to the flange surface of an H-steel constituting a vertical frame structure for a hold wall, wherein the scaffold support device (10) comprises a first clamp pawl (12) that is attached to a main body (11) such that the attached position is adjustable and that is formed on the inner surface thereof with a turning tool cutting-edge (12a) capable of cutting into one side end edge (2a) of the flange surface (2) of the H-steel (1), and a turning arm (20) serving as a support member for a second clamp pawl (23) turnably attached to the right-hand end of the main body (11) through a pivot (29) and formed on the inner surface thereof with a turning tool cutting-edge (23a) capable of cutting into the other side end edge (2b) of the flange surface (2), and wherein a scaffold block (30) is attached to a bracket (28) for the scaffold block (30) welded to the turning arm to turn the turning arm (20) by the weight thereof so as to cause the two clamp pawls to clamp the opposite edges of the flange surface, thereby making it possible to simplify the scaffold construction and reduce the cost.</p> |
