The invention concerns a tier of joists as apartment dividers which consist of light, dry and principally non inflammable material. The frame for the tier of joists consists of load carrying trapezium profiles (8) and transverse thin plate profiles. Apart from this requirement, the tier of joists can be designed with a sprung over-floor, or under-roof, depending on the relevant sound and fire safety requirements, or other requirements which pertain for the construction of the building.<IMAGE> |
