<p>In a scaffold for construction work, four supports (1a,1b) are provided at the respective corners of a rectangle. The front and rear supports on each side are connected to each other by a connecting frame (11) which can be folded without changing its height. After the connecting frames are folded, a scaffolding floor member (6b) provided on the top surface enclosed by the four supports can be lowered by rotating it about one of its ends. <IMAGE></p> |
