The frame forming the platform (1), and the auxiliary frame (2) can be fixed at predetermined positions so as to expand or contract the frame assembly to a desired width. Hanging means (8) are provided at the corners of the frame assembly for connecting a series of assemblies together in a stack by flexible connection means (8) to form a temporary stairway. A ladder (4) is pivotally attached to each frame assembly. &lt;IMAGE&gt;</p>
