<p>PURPOSE:To save the materials by connecting an upper frame and a lower frame laid out on the upper end and the lower end of an assembled scaffolding with a connection material and installing a drive trolley and a follower trolley to the upper frame in such a way that they can run. CONSTITUTION:A T-shaped bracket 20 is mounted to the top of a steel column 2 at the foremost outside of a steel structure 1 (building). Then, an I beam-made rail member 19 is installed to the bracket 20 while a drive trolley 17 and a follower trolley 19 are installed to the rail member 19 in such a fashion that they can run freely. The trolleys 17 and 18 are connected to an upper frame 12 while the upper frame 12 and a lower frame 13 are connected with a round bar 14. Then, a prefabricated scaffolding 11 and a gangway are assembled between the frames 12 and 13, thereby forming an assembled scaffolding.</p> |
