Horizontal pole braces(20,21) are installed on an upper portion of the vertical pole brace(10) across a road in an up and down relationship. A signal light(30) is installed and fixed on the horizontal pole brace(20) so as to direct to the road. A safety net(50) is horizontally fixed on the horizontal pole brace(21) and has a safety rod(51) for safety. A management goes up the safety net(50) and moves along the horizontal pole brace(20). A ladder(4) is installed on the vertical pole brace(10) in order to provide a climbing way to the safety net(50). A signal light(30) is installed on the horizontal pole brace(20) so as to face both directions.
