PURPOSE: To enhance the safety of working by fitting support columns and legs for supporting a working floor into combined pipe pillars each composed of a pair of two pipe members, and by joining the pipe pillars by truss beams. ;CONSTITUTION: Four combined pipe pillars 1a, 1b each composed of a pair of rectangular pipes are planted as four corner pillars, and are joined together by means of truss beams 11 including diagonal members. Further, a leg 3 is fitted in one of the rectangular pipes of each of the combined pipe pillars 1a, 1b, and a support column 10 for supporting a working floor 4 is fitted in the other one of the rectangular pipes thereof. Further, a stopper device for fixing pay-out lengths of the leg 3 and the support column 10 is provided to the rectangular pipes of each of the combined pipe pillars 1a, 1b. Accordingly, the introduction and withdrawal of the scaffold can be facilitated, thereby it is possible to build a temporary scaffold for a high place work in a short time.;COPYRIGHT: (C)1994,JPO&Japio
