Ladder or steel tube frame for building sites is fixed against building structure and has high shelf with bearing faces in same plane as work surface for easy transfer of materials

摘要

The frame is fixed against the building structure (4) and on the side remote from the building there is a high shelf having substantially the same surface area dimensions which is connected to the structural elements of the frame to form a common static assembly. The bearing faces (6) of the high shelf are set in substantially the same plane as the horizontal planks of the work surface (5) so that material can be readily transferred. The frame can be covered by tarpaulin
