摘要

The scaffolding has four vertical posts (2) defining a quadrilateral form, and horizontal braces (3) fixed to the posts. A rectangular floor (5) has length less than a predetermined size, so that the floor is not stably received by the braces. A safety railing (4) is secured to the posts for preventing the fall of personnel working on the scaffolding. The safety railing includes a cylindrical protrusion (6) and a cross-piece (7) for receiving a portion of the floor, where the length of the floor is less than distance between two sets of side vertical posts.
