摘要

The floor or roof girders (10) are interconnected at their lower side by a flexible sheet (15). The assembled unit is pushed together by moving the girders together and folding the sheet, to facilitate transport from factory to building site. The unit is then placed in the required position and the girders moved apart. - The flexible sheet and fastenings are strong enough to carry workers and can also include a heat-insulating layer. This layer and the flexible sheet can be air permeable, to form part of an air circulation system. (Dwg.4/8)
